  • "The sky is the limit; I am going there" : experiences of hope among young women receiving a conditional cash transfer in rural South Africa
  • 2022

    • Young women in South Africa face elevated risk of HIV infection compared to male peers. Cash transfers may mitigate their risk for HIV; however, there is limited understanding of mechanisms of impact. We explored hope as one potential mechanism. Longitudinal qualitative analysis was used to explore how cash transfer recipients in the HPTN 068 study conceptualised hope and how the intervention influenced their hope over time. We found the intervention increased confidence, alleviated financial stressors and instilled in young women the belief that a better life, defined as being educated, independent and supportive to family, was attainable. Findings support hope as a critical outcome of cash transfer and other economic strengthening interventions.

  • Introducing visual participatory methods to develop local knowledge on HIV in rural South Africa
  • 2017
  • Ingår i: BMJ Global Health. - : BMJ Publishing Group Ltd. - 2059-7908. ; 2:3
  • Tidskriftsartikel (refereegranskat)abstract
    • INTRODUCTION: South Africa is a country faced with complex health and social inequalities, in which HIV/AIDS has had devastating impacts. The study aimed to gain insights into the perspectives of rural communities on HIV-related mortality.METHODS: A participatory action research (PAR) process, inclusive of a visual participatory method (Photovoice), was initiated to elicit and organise local knowledge and to identify priorities for action in a rural subdistrict underpinned by the Agincourt Health and Socio-Demographic Surveillance System (HDSS). We convened three village-based discussion groups, presented HDSS data on HIV-related mortality, elicited subjective perspectives on HIV/AIDS, systematised these into collective accounts and identified priorities for action. Framework analysis was performed on narrative and visual data, and practice theory was used to interpret the findings.FINDINGS: A range of social and health systems factors were identified as causes and contributors of HIV mortality. These included alcohol use/abuse, gender inequalities, stigma around disclosure of HIV status, problems with informal care, poor sanitation, harmful traditional practices, delays in treatment, problems with medications and problematic staff-patient relationships. To address these issues, developing youth facilities in communities, improving employment opportunities, timely treatment and extending community outreach for health education and health promotion were identified.DISCUSSION: Addressing social practices of blame, stigma and mistrust around HIV-related mortality may be a useful focus for policy and planning. Research that engages communities and authorities to coproduce evidence can capture these practices, improve communication and build trust.CONCLUSION: Actions to reduce HIV should go beyond individual agency and structural forces to focus on how social practices embody these elements. Initiating PAR inclusive of visual methods can build shared understandings of disease burdens in social and health systems contexts. This can develop shared accountability and improve staff-patient relationships, which, over time, may address the issues identified, here related to stigma and blame.

  • Associations of physical activity and gross motor skills with executive function in preschool children from low-income South African settings
  • 2019
  • Ingår i: Developmental Science. - : John Wiley & Sons. - 1363-755X .- 1467-7687. ; 22:5, s. 1-13
  • Tidskriftsartikel (refereegranskat)abstract
    • Executive function is foundational for cognitive development. Previous research has shown both gross motor skills and physical activity to be related to executive function. However, evidence for these relationships in the preschool years, as well as in low- and middle-income countries is lacking. Therefore, this study aimed to investigate the relationships between components of executive function (inhibition, shifting and working memory) and gross motor skills (locomotor skills and object control skills) in a sample of preschool children from urban and rural low-income settings in South Africa. Results revealed that inhibition and working memory, but not shifting, were associated with gross motor skills. More specifically: inhibition was associated with both locomotor [beta = 0.20, p = 0.047] and object control skills [beta = 0.24, p = 0.024], whereas working memory was only associated with locomotor skills [beta = 0.21, p = 0.039]. Physical activity was not associated with inhibition and shifting but was negatively associated with working memory. These results elaborate a growing evidence base linking executive function and gross motor skills in the early years, and it is the first to look at specific associations of locomotor and object control skills with executive function in the South African context (a low- and middle-income country).

  • Understanding non-communicable diseases : combining health surveillance with local knowledge to improve rural primary health care in South Africa
  • 2021
  • Ingår i: Global Health Action. - : Taylor & Francis. - 1654-9716 .- 1654-9880. ; 14:1
  • Tidskriftsartikel (refereegranskat)abstract
    • Background: NCDs are non-infectious, long-term conditions that account for 40 million deaths per annum. 87% of premature NCD mortality occurs in low- and middle-income countries.Objective: The aims were:develop methods to provide integrated biosocial accounts of NCD mortality; and explore the practical utility of extended mortality data for the primary health care system.Methods: We drew on data from research programmes in the study area. Data were analysed in three steps: [a]analysis of levels, causes and circumstances of NCD mortality [n = 4,166] from routine census updates including Verbal Autopsy and of qualitative data on lived experiences of NCDs in rural villages from participatory research; [b] identifying areas of convergence and divergence between the analyses; and [c]exploration of the practical relevance of the data drawing on engagements with health systems stakeholders.Results: NCDs constituted a significant proportion of mortality in this setting [36%]. VA data revealed multiple barriers to access in end-of-life care. Many deaths were attributed to problems with resources and health systems [21%;19% respectively]. The qualitative research provided rich complementary detail on the processes through which risk originates, accumulates and is expressed in access to end-of-life care, related to chronic poverty and perceptions of poor quality care in clinics. The exploration of practical relevance revealed chronic under-funding for NCD services, and an acute need for robust, timely data on the NCD burden.Conclusions: VA data allowed a significant burden of NCD mortality to be quantified and revealed barriers to access at and around the time of death. Qualitative research contextualised these barriers, providing explanations of how and why they exist and persist. Health systems analysis revealed shortages of resources allocated to NCDs and a need for robust research to provide locally relevant evidence to organise and deliver care. Pragmatic interdisciplinary and mixed method analysis provides relevant renditions of complex problems to inform more effective responses.

  • Rethinking collaboration : developing a learning platform to address under-five mortality in Mpumalanga province, South Africa
  • 2019
  • Ingår i: Health Policy and Planning. - : Oxford University Press. - 0268-1080 .- 1460-2237. ; 34:6, s. 418-429

    • Following 50 years of apartheid, South Africa introduced visionary health policy committing to the right to health as part of a primary health care (PHC) approach. Implementation is seriously challenged, however, in an often-dysfunctional health system with scarce resources and a complex burden of avoidable mortality persists. Our aim was to develop a process generating evidence of practical relevance on implementation processes among people excluded from access to health systems. Informed by health policy and systems research, we developed a collaborative learning platform in which we worked as co-researchers with health authorities in a rural province. This article reports on the process and insights brought by health systems stakeholders. Evidence gaps on under-five mortality were identified with a provincial Directorate after which we collected quantitative and qualitative data. We applied verbal autopsy to quantify levels, causes and circumstances of deaths and participatory action research to gain community perspectives on the problem and priorities for action. We then re-convened health systems stakeholders to analyse and interpret these data through which several systems issues were identified as contributory to under-five deaths: staff availability and performance; service organization and infrastructure; multiple parallel initiatives; and capacity to address social determinants. Recommendations were developed ranging from immediate low- and no-cost re-organization of services to those where responses from higher levels of the system or outside were required. The process was viewed as acceptable and relevant for an overburdened system operating 'in the dark' in the absence of local data. Institutional infrastructure for evidence-based decision-making does not exist in many health systems. We developed a process connecting research evidence on rural health priorities with the means for action and enabled new partnerships between communities, authorities and researchers. Further development is planned to understand potential in deliberative processes for rural PHC.

  • ‘Voice needs teeth to have bite’! Expanding community-led multisectoral action-learning to address alcohol and drug abuse in rural South Africa
  • 2022
  • Ingår i: PLOS Global Public Health. - : Public Library of Science (PLoS). - 2767-3375. ; 2:10
  • Tidskriftsartikel (refereegranskat)abstract
    • There is limited operational understanding of multisectoral action in health inclusive of communities as active change agents. The objectives were to: (a) develop community-led action-learning, advancing multisectoral responses for local public health problems; and (b) derive transferrable learning. Participants representing communities, government departments and non-governmental organisations in a rural district in South Africa co-designed the process. Participants identified and problematised local health concerns, coproduced and collectively analysed data, developed and implemented local action, and reflected on and refined the process. Project data were analysed to understand how to expand community-led action across sectors. Community actors identified alcohol and other drug (AOD) abuse as a major problem locally, and generated evidence depicting a self-sustaining problem, destructive of communities and disproportionately affecting children and young people. Community and government actors then developed action plans to rebuild community control over AOD harms. Implementation underscored community commitment, but also revealed organisational challenges and highlighted the importance of coordination with government reforms. While the action plan was only partially achieved, new relationships and collective capabilities were built, and the process was recommended for integration into district health planning and review. We created spaces engaging otherwise disconnected stakeholders to build dialogue, evidence, and action. Engagement needed time, space, and a sensitive, inclusive approach. Regular engagement helped develop collaborative mindsets. Credible, actionable information supported engagement. Collectively reflecting on and adapting the process supported aligning to local systems priorities and enabled uptake. The process made gains raising community ‘voice’ and initiating dialogue with the authorities, giving the voice ‘teeth’. Achieving ‘bite’, however, requires longer-term engagement, formal and sustained connections to the system. Sustaining in highly fluid contexts and connecting to higher levels are likely to be challenging. Regular learning spaces can support development of collaborative

  • Cross-sectional associations of physical activity and gross motor proficiency with adiposity in South African children of pre-school age
  • 2019
  • Ingår i: Public Health Nutrition. - : Cambridge University Press. - 1368-9800 .- 1475-2727. ; 22:4, s. 614-623
  • Tidskriftsartikel (refereegranskat)abstract
    • Objective: The study aimed to investigate the relationship between physical activity, gross motor skills and adiposity in South African children of pm-school age.Design: Cross-sectional study.Setting: High-income urban, and low-income urban and rural settings in South Africa.Participants: Children (3-6 years old, n 268) were recruited from urban high-income (n 46), urban low-income (n 91) and rural low-income (n 122) settings. Height and weight were measured to calculate the main outcome variables: BMI and BMI-for-age Z-score (BAZ). Height-for-age and weight-for-age Z-scores were also calculated. Actigraph GT3X+ accelerometers were used to objectively measure physical activity; the Test of Gross Motor Development (Version 2) was used to assess gross motor skills.Results: More children were overweight/obese and had a higher BAZ from urban low-income settings compared with urban high-income settings and rural low-income settings. Being less physically active was associated with thinness, but not overweight/obesity. Time spent in physical activity at moderate and vigorous intensities was positively associated with BMI and BAZ. Gross motor proficiency was not associated with adiposity in this sample.Conclusions: The findings of this research highlight the need for obesity prevention particularly in urban low-income settings, as well as the need to take into consideration the complexity of the relationship between adiposity, physical activity and gross motor skills in South African pre-school children.

  • Developing Intervention Strategies to Optimise Body Composition in Early Childhood in South Africa
  • 2017
  • Ingår i: BioMed Research International. - : HINDAWI LTD. - 2314-6133 .- 2314-6141.
  • Tidskriftsartikel (refereegranskat)abstract
    • Purpose. The purpose of this research was to collect data to inform intervention strategies to optimise body composition in South African preschool children. Methods. Data were collected in urban and rural settings. Weight status, physical activity, and gross motor skill assessmentswere conducted with 341 3-6-year-old children, and 55 teachers and parents/caregivers participated in focus groups. Results. Overweight and obesity were a concern in low-income urban settings (14%), but levels of physical activity and gross motor skills were adequate across all settings. Focus group findings from urban and rural settings indicated that teachers would welcome input on leading activities to promote physical activity and gross motor skill development. Teachers and parents/caregivers were also positive about young children being physically active. Recommendations for potential intervention strategies include a teacher-training component, parent/child activitymornings, and a home-based component for parents/caregivers. Conclusion. The findings suggest that an intervention focussed on increasing physical activity and improving gross motor skills per se is largely not required but that contextually relevant physical activity and gross motor skills may still be useful for promoting healthy weight and a vehicle for engaging with teachers and parents/caregivers for promoting other child outcomes, such as cognitive development.

  • Gender Norms, Gender Role Conflict/Stress and HIV Risk Behaviors Among Men in Mpumalanga, South Africa
  • 2018
  • Ingår i: Aids and Behavior. - : Springer. - 1090-7165 .- 1573-3254. ; 22:6, s. 1858-1869
  • Tidskriftsartikel (refereegranskat)abstract
    • Men's gender role conflict and stress (GRC/S), the psychological strain they experience around fulfilling expectations of themselves as men, has been largely unexplored in HIV prevention research. We examined associations between both men's gender norms and GRC/S and three HIV risk behaviors using data from a population-based survey of 579 18-35 year-old men in rural northeast South Africa. Prevalence of sexual partner concurrency and intimate partner violence (IPV) perpetration in the last 12 months were 38.0 and 13.4%, respectively; 19.9% abused alcohol. More inequitable gender norms and higher GRC/S were each significantly associated with an increased odds of concurrency (p = 0.01; p < 0.01, respectively), IPV perpetration (p = 0.03; p < 0.01), and alcohol abuse (p = 0.02; p < 0.001), controlling for demographic characteristics. Ancillary analyses demonstrated significant positive associations between: concurrency and the GRC/S sub-dimension subordination to women; IPV perpetration and restrictive emotionality; and alcohol abuse and success, power, competition. Programs to transform gender norms should be coupled with effective strategies to prevent and reduce men's GRC/S.

  • Measuring Men's Gender Norms and Gender Role Conflict/Stress in a High HIV-Prevalence South African Setting
  • 2016
  • Ingår i: Aids and Behavior. - : Springer Science and Business Media LLC. - 1090-7165 .- 1573-3254. ; 20:8, s. 1785-1795
  • Tidskriftsartikel (refereegranskat)abstract
    • Gender norms and gender role conflict/stress may influence HIV risk behaviors among men; however scales measuring these constructs need further development and evaluation in African settings. We conducted exploratory and confirmatory factor analyses to evaluate the Gender Equitable Men's Scale (GEMS) and the Gender Role Conflict/Stress (GRC/S) scale among 581 men in rural northeast South Africa. The final 17-item GEMS was unidimensional, with adequate model fit and reliability (alpha = 0.79). Factor loadings were low (0.2-0.3) for items related to violence and sexual relationships. The final 24-item GRC/S scale was multidimensional with four factors: Success, power, competition; Subordination to women; Restrictive emotionality; and Sexual prowess. The scale had adequate model fit and good reliability (alpha = 0.83). While GEMS is a good measure of inequitable gender norms, new or revised scale items may need to be explored in the South African context. Adding the GRC/S scale to capture men's strain related to gender roles could provide important insights into men's risk behaviors.

  • Developing stakeholder participation to address lack of safe water as a community health concern in a rural province in South Africa
  • 2021
  • Ingår i: Global Health Action. - : Taylor & Francis. - 1654-9716 .- 1654-9880. ; 14:1
  • Tidskriftsartikel (refereegranskat)abstract
    • Background: Despite legislative and policy commitments to participatory water governance in South Africa, and some remarkable achievements, there has been limited progress to improve the water infrastructure servicing in marginalized rural communities. Around five million South Africans still do not have access to safe water. Objective: This paper seeks to understand and advance processes to engage multisectoral stakeholders to respond to lack of safe water as a community-nominated health priority in rural South Africa.Method: We engaged representatives from Mpumalanga Department of Health (MDoH), rural communities, other government departments and non-governmental organisations (NGOs) to cooperatively generate, interpret and act on evidence addressing community-nominated priorities. A series of participatory workshops were conducted where stakeholders worked together as co-researchers to develop shared accounts of the problem, and recommendations to address it. Consensus on the problem, mapping existing planning and policy landscapes, and initiating constructive dialogue was facilitated through group discussions in a collective learning process.Results: Community stakeholders nominated lack of safe water as a local priority public health issue and generated evidence on causes and contributors, and health and social impacts. Together with government and NGO stakeholders, this evidence was corroborated. Stakeholders developed a local action plan through consensus and feasibility appraisal. Actions committed to behavioural change and reorganization of existing services, were relevant to the needs of the local community and were developed with consideration of current policies and strategies. A positive, collective reflection was made on the process. The greatest gain reported was the development of dialogue in ‘safe spaces’ through which mutual understanding, insights into the functioning of other sectors and learning by doing were achieved.Conclusion: Our process reflected willingness and commitment among stakeholders to work together collectively addressing local water challenges. Location in an established public health observatory helped to create neutral, mediated spaces for participation.

  • Lessons from community participation in primary health care and water resource governance in South Africa : a narrative review
  • 2022
  • Ingår i: Global Health Action. - : Taylor & Francis. - 1654-9716 .- 1654-9880. ; 15:1
  • Forskningsöversikt (refereegranskat)abstract
    • Background: In South Africa, community participation has been embraced through the development of progressive policies to address past inequities. However, limited information is available to understand community involvement in priority setting, planning and decision-making in the development and implementation of public services.Objective: This narrative review aims to provide evidence on forms, extents, contexts and dynamics of community participation in primary health care (PHC) and water governance in South Africa and draw cross-cutting lessons. This paper focuses on health and water governance structures, such as health committees, Catchment Management Agencies (CMA), Water User Associations (WUAs), Irrigation Boards (IBs) and Community Management Forums (CMFs).Methods: Articles were sourced from Medline (Ovid), EMBASE, Google Scholar, Web of Science, WHO Global Health Library, Global Health and Science Citation Index between 1994 and 2020 reporting on community participation in health and water governance in South Africa. Databases were searched using key terms to identify relevant research articles and grey literature. Twenty-one articles were included and analysed thematically.Results: There is limited evidence on how health committees are functioning in all provinces in South Africa. Existing evidence shows that health committees are not functioning effectively due to lack of clarity on roles, autonomy, power, support, and capacity. There was slow progress in establishment of water governance structures, although these are autonomous and have mechanisms for democratic control, unlike health committees. Participation in CMAs/WUAs/IBs/CMFs is also not effective due to manipulation of spaces by elites, lack of capacity of previously disadvantaged individuals, inadequate incentives, and low commitment to the process by stakeholders.Conclusion: Power and authority in decision-making, resources and accountability are key for effective community participation of marginalized people. Practical guidance is urgently required on how mandated participatory governance structures can be sustained and linked to wider governance systems to improve service delivery.

  • Participatory action research to address lack of safe water, a community-nominated health priority in rural South Africa
  • 2023
  • Ingår i: PLOS ONE. - : Public Library of Science (PLoS). - 1932-6203. ; 18:7
  • Tidskriftsartikel (refereegranskat)abstract
    • BACKGROUND: Despite international evidence supporting community participation in health for improved health outcomes and more responsive and equitable health systems there is little practical evidence on how to do this. This work sought to understand the process involved in collective implementation of a health-related local action plan developed by multiple stakeholders.METHODS: Communities, government departments and non-government stakeholders convened in three iterative phases of a participatory action research (PAR) learning cycle. Stakeholders were involved in problem identification, development, and implementation of a local action plan, reflection on action, and reiteration of the process. Participants engaged in reflective exercises, exploring how factors such as power and interest impacted success or failure.RESULTS: The local action plan was partially successful, with three out of seven action items achieved. High levels of both power and interest were key factors in the achievement of action items. For the achieved items, stakeholders reported that continuous interactions with one another created a shift in both power and interest through ownership of implementation processes. Participants who possessed significant power and influence were able to leverage resources and connections to overcome obstacles and barriers to progress the plan. Lack of financial support, shifting priorities and insufficient buy-in from stakeholders hindered implementation.CONCLUSION: The process offered new ways of thinking and stakeholders were supported to generate local evidence for action and learning. The process also enabled exploration of how different stakeholders with different levels of power and interest coalesce to design, plan, and act on evidence. Creation of safe spaces was achievable, meanwhile changing stakeholders' level of power and interest was possible but challenging. This study suggests that when researchers, service providers and communities are connected as legitimate participants in a learning platform with access to information and decision-making, a shift in power and interest may be feasible.

  • 'Water is life' : developing community participation for clean water in rural South Africa
  • 2019
  • Ingår i: BMJ Global Health. - : BMJ Publishing Group Ltd. - 2059-7908. ; 4:3
  • Tidskriftsartikel (refereegranskat)abstract
    • Background South Africa is a semiarid country where 5 million people, mainly in rural areas, lack access to water. Despite legislative and policy commitments to the right to water, cooperative governance and public participation, many authorities lack the means to engage with and respond to community needs. The objectives were to develop local knowledge on health priorities in a rural province as part of a programme developing community evidence for policy and planning. Methods We engaged 24 participants across three villages in the Agincourt Health and Socio-Demographic Surveillance System and codesigned the study. This paper reports on lack of clean, safe water, which was nominated in one village (n=8 participants) and in which women of reproductive age were nominated as a group whose voices are excluded from attention to the issue. On this basis, additional participants were recruited (n=8). We then held a series of consensus-building workshops to develop accounts of the problem and actions to address it using Photovoice to document lived realities. Thematic analysis of narrative and visual data was performed. Results Repeated and prolonged periods when piped water is unavailable were reported, as was unreliable infrastructure, inadequate service delivery, empty reservoirs and poor supply exacerbated by droughts. Interconnected social, behavioural and health impacts were documented combined with lack of understanding, cooperation and trust between communities and authorities. There was unanimity among participants for taps in houses as an overarching goal and strategies to build an evidence base for planning and advocacy were developed. Conclusion In this setting, there is willingness among community stakeholders to improve water security and there are existing community assemblies to support this. Health and Socio-Demographic Surveillance Systems provide important opportunities to routinely connect communities to resource management and service delivery. Developing learning platforms with government and non-government organisations may offer a means to enable more effective public participation in decentralised water governance.

  • Challenging socioeconomic status : A cross-cultural comparison of early executive function
  • 2020
  • Ingår i: Developmental Science. - : John Wiley & Sons. - 1363-755X .- 1467-7687. ; 23:1
  • Tidskriftsartikel (refereegranskat)abstract
    • The widely and internationally replicated socioeconomic status (SES) gradient of executive function (EF) implies that intervention approaches may do well to extrapolate conditions and practices from contexts that generate better child outcomes (in this case, higher SES circumstances) and translate these to contexts with comparatively poorer outcomes (often low-SES populations). Yet, can the reverse also be true? Using data from equivalent assessments of 1,092 pre-schoolers' EFs in South Africa and Australia, we evaluated: the SES gradient of EF within each sample; and whether this SES gradient extended cross-culturally. The oft-found EF-SES gradients were replicated in both samples. However, contrary to the inferences of EF-SES associations found nationally, the most highly disadvantaged South African subsample outperformed middle- and high-SES Australian pre-schoolers on two of three EFs. This suggests the possibility of EF-protective and -promotive practices within low- and middle-income countries that may aid understandings of the nature and promotion of EFs.

  • Enhancing the value of mortality data for health systems : adding Circumstances Of Mortality CATegories (COMCATs) to deaths investigated by verbal autopsy
  • 2019
  • Ingår i: Global Health Action. - : Taylor & Francis. - 1654-9716 .- 1654-9880. ; 12:1
  • Tidskriftsartikel (refereegranskat)abstract
    • Half of the world’s deaths and their causes pass unrecorded by routine registration systems, particularly in low- and middle-income countries. Verbal autopsy (VA) collects information on medical signs, symptoms and circumstances from witnesses of a death that is used to assign likely medical causes. To further contextualise information on mortality, understanding underlying determinants, such as logistics, barriers to service utilisation and health systems responses, is important for health planning. Adding systematic methods for categorising circumstantial determinants of death to conventional VA tools is therefore important. In this context, the World Health Organization (WHO) leads the development of international standards for VA, and added questions on the social and health systems circumstances of death in 2012. This paper introduces a pragmatic and scalable approach for assigning relevant Circumstances Of Mortality CATegories (COMCATs) within VA tools, and examines their consistency, reproducibility and plausibility for health policy making, as well as assessing additional effort and cost to the routine VA process. This innovative COMCAT model is integrated with InterVA-5 software (which processes WHO-2016 VA data), for assigning numeric likelihoods to six circumstantial categories for each death. VA data from 4,116 deaths in the Agincourt Health and Socio-Demographic Surveillance System in South Africa from 2012 to 2016 were used to demonstrate proof of principle for COMCATs. Lack of resources to access health care, poor recognition of diseases and inadequate health systems responses ranked highest among COMCATs in the demonstration dataset. COMCATs correlated plausibly with age, sex, causes of death and local knowledge of the demonstration population. The COMCAT approach appears to be plausible, feasible and enhances the functionality of routine VA to account for critical limiting circumstances at and around the time of death. It is a promising tool for evaluating progress towards the Sustainable Development Goals and the roll-out of Universal Health Coverage.

  • Associations between WASH-related violence and depressive symptoms in adolescent girls and young women in South Africa (HPTN 068) : a cross-sectional analysis
  • 2022
  • Ingår i: BMJ Open. - : BMJ Publishing Group Ltd. - 2044-6055. ; 12:7
  • Tidskriftsartikel (refereegranskat)abstract
    • OBJECTIVE: There is a lack of research on experiences of WASH-related violence. This study aims to quantify the association between experience or worry of violence when using the toilet or collecting water and depressive symptoms among a cohort of young women in South Africa.METHODS: Data are from visit 3 of the HPTN 068 cohort of adolescent girls in rural Mpumalanga Province, South Africa. Participants (n=1798) included in this analysis were aged 13-21 at baseline. Lifetime experience of violence or fear of violence when using the toilet and collecting water was collected by self-report; depressive symptoms in the past week were measured using the Center for Epidemiological Studies Depression Scale (CES-D). We used G-computation to calculate the prevalence difference (PD) and prevalence ratio of depression (CES-D score >15) associated with each domain of violence, controlling for baseline covariates.FINDINGS: A total of 15.1% of respondents reported experiencing violence when using the toilet; 17.1% reported experiencing violence when collecting water and 26.7% reported depression. In adjusted models, those who reported experiencing violence when using the toilet had an 18.1% higher prevalence of depression (95% CI: 11.6% to 24.4%) than those who did not experience violence when using the toilet. Adjusted prevalence of depression was also higher among those who reported violence when collecting water (PD 11.9%, 95% CI: 6.7% to 17.2%), and who worried about violence when using the toilet (PD 12.8%, 95% CI: 7.9% to 19.8%), as compared with those who did not report these experiences. Worrying about violence when collecting water was not associated with depression after adjusting for covariates.CONCLUSION: Experience of WASH-related violence is common among young women in rural South Africa, and experience or worry of experiencing violence is associated with higher prevalence of depressive symptoms.TRIAL REGISTRATION NUMBER: NCT01233531; Post-results.

    • The Agincourt health and socio-demographic surveillance system (HDSS), located in rural northeast South Africa close to the Mozambique border, was established in 1992 to support district health systems development led by the post-apartheid ministry of health. The HDSS (90 000 people), based on an annual update of resident status and vital events, now supports multiple investigations into the causes and consequences of complex health, population and social transitions. Observational work includes cohorts focusing on different stages along the life course, evaluation of national policy at population, household and individual levels and examination of household responses to shocks and stresses and the resulting pathways influencing health and well-being. Trials target children and adolescents, including promoting psycho-social well-being, preventing HIV transmission and reducing metabolic disease risk. Efforts to enhance the research platform include using automated measurement techniques to estimate cause of death by verbal autopsy, full 'reconciliation' of in- and out-migrations, follow-up of migrants departing the study area, recording of extra-household social connections and linkage of individual HDSS records with those from sub-district clinics. Fostering effective collaborations (including INDEPTH multi-centre work in adult health and ageing and migration and urbanization), ensuring cross-site compatibility of common variables and optimizing public access to HDSS data are priorities.

  • Research into health, population, and social transitions in rural South Africa : data and methods of the Agincourt health and demographic surveillance system
  • 2007
  • Ingår i: Scandinavian Journal of Public Health. - : Sage Publications. - 1403-4948 .- 1651-1905. ; 35:Suppl. 69, s. 8-20
  • Tidskriftsartikel (refereegranskat)abstract
    • Rationale for study: Vital registration is generally lacking in infrastructurally weak areas where health and development problems are most pressing. Health and demographic surveillance is a response to the lack of a valid information base that can provide high-quality longitudinal data on population dynamics, health, and social change to inform policy and practice. Design and measurement procedures: Continuous demographic monitoring of an entire geographically defined population involves a multi-round, prospective community study, with annual recording of all vital events (births, deaths, migrations). Status observations and special modules add value to particular research areas. A verbal autopsy is conducted on every death to determine its probable cause. A geographic surveillance system supports spatial analyses, and strengthens field management.Population and sample size considerations: Health and demographic surveillance covers the Agincourt sub-district population, sited in rural north-eastern South Africa, of some 70,000 people (nearly a third are Mozambican immigrants) in 21 villages and 11,700 households. Data enumerated are consistent or more detailed when compared with national sources; strategies to improve incomplete data, such as counts of perinatal deaths, have been introduced with positive effect.Basic characteristics: A major health and demographic transition was documented over a 12-year period with marked changes in population structure, escalating mortality, declining fertility, and high levels of temporary migration increasing particularly amongst women. A dual burden of infectious and non-communicable disease exists against a background of dramatically progressing HIV/AIDS.Potential and research questions: Health and demographic surveillance sites - fundamental to the INDEPTH Network - generate research questions and hypotheses from empirical data, highlight health, social and population priorities, provide cost-effective support for diverse study designs, and track population change and the impact of interventions over time.

  • Conditional cash transfers and the reduction in partner violence for young women : an investigation of causal pathways using evidence from a randomized experiment in South Africa (HPTN 068)
  • 2018
  • Ingår i: Journal of the International AIDS Society. - : JOHN WILEY & SONS LTD. - 1758-2652. ; 21
  • Tidskriftsartikel (refereegranskat)abstract
    • IntroductionEvidence has shown that the experience of violence by a partner has important influences on women's risk of HIV acquisition. Using a randomized experiment in northeast South Africa, we found that a conditional cash transfer (CCT) targeted to poor girls in high school reduced the risk of physical intimate partner violence (IPV) in the past 12months by 34%. The purpose of this analysis is to understand the pathways through which the CCT affects IPV. MethodsHPTN 068 was a phase 3, randomized controlled trial in rural Mpumalanga province, South Africa. Eligible young women (aged 13-20) and their parents or guardians were randomly assigned (1:1) to either receive a monthly cash transfer conditional on monthly high school attendance or no cash transfer. Between 2011 and 2015, participants (N=2,448) were interviewed at baseline, then at annual follow-up visits at 12, 24 and 36months. The total effect of the CCT on IPV was estimated using a GEE log-binomial regression model. We then estimated controlled direct effects to examine mediation of direct effects through intermediate pathways. Mediators include sexual partnership measures, the sexual relationship power scale, and household consumption measures. ResultsWe found evidence that the CCT works in part through delaying sexual debut or reducing the number of sexual partners. The intervention interacts with these mediators leading to larger reductions in IPV risk compared to the total effect of the CCT on any physical IPV [RR 0.66, CI(95%):0.59-0.74]. The largest reductions are seen when we estimate the controlled direct effect under no sexual debut [RR 0.57, CI(95%):0.48-0.65] or under no sexual partner in the last 12months [RR 0.53, CI(95%):0.46-0.60]. ConclusionsResults indicate that a CCT for high school girls has protective effects on their experience of IPV and that the effect is due in part to girls choosing not to engage in sexual partnerships, thereby reducing the opportunity for IPV. As a lower exposure to IPV and safer sexual behaviours also protect against HIV acquisition, this study adds to the growing body of evidence on how cash transfers may reduce young women's HIV risk.

  • A model for promoting physical activity among rural South African adolescent girls
  • 2015
  • Ingår i: Global Health Action. - : Co-Action Publishing. - 1654-9716 .- 1654-9880. ; 8
  • Tidskriftsartikel (refereegranskat)abstract
    • BACKGROUND: In South Africa, the expanding epidemic of non-communicable diseases is partly fuelled by high levels of physical inactivity and sedentary behaviour. Women especially are at high risk, and interventions promoting physical activity are urgently needed for girls in their adolescence, as this is the time when many girls adopt unhealthy lifestyles.OBJECTIVE: This qualitative study aimed to identify and describe facilitating factors and barriers that are associated with physical activity among adolescent girls in rural, north-eastern South Africa and, based on these, to develop a model for promoting leisure-time physical activity within this population.DESIGN: The study was conducted in and around three secondary schools. Six focus group discussions were conducted with adolescent girls from the schools, and seven qualitative interviews were held with sports teachers and youth leaders. The data were subjected to thematic analysis.RESULTS: Seven thematic areas were identified, each of which was associated with the girls' self-reported levels of physical activity. The thematic areas are 1) poverty, 2) body image ideals, 3) gender, 4) parents and home life, 5) demographic factors, 6) perceived health effects of physical activity, and 7) human and infrastructural resources. More barriers to physical activity were reported than facilitating factors.CONCLUSIONS: Analysis of the barriers found in the different themes indicated potential remedial actions that could be taken, and these were synthesised into a model for promoting physical activity among South African adolescent girls in resource-poor environments. The model presents a series of action points, seen both from the 'supply-side' perspective (such as the provision of resources and training for the individuals, schools, and organisations which facilitate the activities) and from the 'demand-side' perspective (such as the development of empowering messages about body image for teenage girls, and encouraging more parental involvement). The development of physical activity interventions that incorporate this supply- and demand-side model would represent an additional tool for ongoing efforts aimed at tackling the expanding non-communicable disease epidemic in South Africa, and in other resource-constrained settings undergoing rapid health transitions.

  • Community collective efficacy is associated with reduced physical intimate partner violence (IPV) incidence in the rural province of Mpumalanga, South Africa : findings from HPTN 068
  • 2019
  • Ingår i: Journal of Epidemiology and Community Health. - : BMJ Publishing Group Ltd. - 0143-005X .- 1470-2738. ; 73:2, s. 176-181
  • Tidskriftsartikel (refereegranskat)abstract
    • Background Intimate partner violence (IPV) is a human rights violation and is associated with a variety of adverse physical and mental health outcomes. Collective efficacy, defined as mutual trust among community members and willingness to intervene on the behalf of the common good, has been associated with reduced neighbourhood violence. Limited research has explored whether community collective efficacy is associated with reduced incidence of IPV. This is of particular interest among adolescent girls and young women (AGYW) in sub-Saharan Africa, where the burden of HIV is greatest and IPV is common. Methods We collected longitudinal data among 2533 AGYW (ages 13-20) enrolled in the HPTN 068 cohort in Mpumalanga province, South Africa between 2011 and 2016. We included participants from 26 villages where community surveys were collected during the HPTN 068 study. Collective efficacy was measured at the village level via two population-based cross-sectional surveys in 2012 and 2014. Multivariable Poisson generalised estimating equation regression models estimated the relative risk ratio (RR) between village collective efficacy scores and subsequent physical IPV 12 month incidence, adjusting for village-level clustering and covariates. Results Thirty-eight per cent of the cohort (n=950) reported at least one episode of recent physical IPV during follow-up. For every SD higher level of collective efficacy, there was a 6% lower level of physical IPV incidence (adjusted RR: 0.94; 95% CI 0.89 to 0.98) among AGYW after adjusting for covariates. Conclusions Community-level interventions that foster the development of collective efficacy may reduce IPV among AGYW.

    • Limited research has explored how emotional intimate partner violence (IPV) shapes HIV risk behaviors. Using cross-sectional data from the HPTN 068 post-trial visit (N = 1942), we assessed the association between emotional IPV and its sub-domains (verbal abuse and threats) with condomless sex, transactional sex, and frequent alcohol use among young women in South Africa. In adjusted multivariable logistic regression models, any emotional IPV and verbal IPV were associated with increased odds of condomless sex (aOR: 1.47; 95% CI: 1.15, 1.87; and aOR: 1.48; 95% CI: 1.15, 1.89), transactional sex (aOR: 2.32; 95% CI: 1.74, 3.08; and aOR: 2.02; 95% CI: 1.51, 2.71) and alcohol use (aOR: 1.88; 95% CI: 1.39, 2.53; and aOR: 1.87; 95% CI: 1.37, 2.55). Threats were associated with transactional sex (aOR: 3.67; 95% CI: 2.62, 5.14). Future research should examine this relationship over-time and HIV prevention programs should consider and address emotional IPV.

  • Examining Mediators of the Relationship Between Community Mobilization and HIV Incidence Among Young South African Women Participating in the HPTN 068 Study Cohort
  • 2022
  • Ingår i: Aids and Behavior. - : Springer. - 1090-7165 .- 1573-3254. ; 26:5, s. 1347-1354
  • Tidskriftsartikel (refereegranskat)abstract
    • We previously demonstrated that village community mobilization (CM) was associated with reduced HIV incidence among adolescent girls and young women (AGYW) in South Africa. Little remains known about the mechanisms linking CM to HIV incidence. Using longitudinal data from 2292 AGYW in the HPTN 068 cohort (2011–2017), we examined whether school attendance, pro-social engagement, and hope for the future mediated the relationship between CM and HIV incidence. CM was measured at the village-level via two population-based surveys (2012 and 2014). Mediators and incident HIV infection were measured through HPTN 068 surveys and HIV testing. Mediation analyses were conducted using Mplus 8.5, adjusting for village-level clustering and covariates. Hope for the future mediated the relationship between CM and HIV incidence (indirect effect-RR 0.98, bias-corrected 95% CI 0.96, 0.99). Pro-social engagement and school attendance did not demonstrate indirect effects. CM reduces AGYW’s HIV acquisition risk, in part, by engendering hope.

  • A community mobilisation intervention to improve engagement in HIV testing, linkage to care, and retention in care in South Africa : a cluster-randomised controlled trial
  • 2022
  • Ingår i: The Lancet HIV. - : Elsevier. - 2405-4704 .- 2352-3018. ; 9:9, s. e617-e626

    • Background: Community mobilisation, engaging communities in a process to collectively enact change, could improve HIV testing and care engagement. In South Africa, current rates fall below those needed for epidemic control. We assessed whether community mobilisation increased HIV testing, linkage to care, and retention in care over time in intervention relative to control communities.Methods: We conducted a cluster-randomised controlled trial in villages in the Agincourt sub-district of the rural Mpumalanga Province in South Africa. 15 villages were randomly assigned to either a community mobilisation intervention engaging residents to address social barriers to HIV testing and treatment (intervention arm) or to a control arm using balanced randomisation. Villages were eligible if they had been fully enumerated in 2014, had not been included in previous mobilisation activities, and included over 500 permanent adult residents aged 18–49 years. Primary outcomes included quarterly rates of HIV testing, linkage to care, and retention in care documented from health facility records among residents of the intervention and control communities over the 3-year study period. Intention-to-treat analyses employed generalised estimating equations stratified by sex. This trial is registered with ClinicalTrials.gov, NCT02197793.Findings: Between Aug 1, 2015, and July 31, 2018, residents in eight intervention communities (n=20 544 residents) and seven control communities (n=17 848) contributed data; 92 residents contributed to both arms. Among men, HIV testing increased quarterly by 12·1% (relative change [RC] 1·121, 95% CI 1·099 to 1·143, p<0·0001) in the intervention communities and 9·5% (1·095, 1·075 to 1·114, p=0·011) in the control communities; although increases in testing were greater in the intervention villages, differences did not reach significance (exponentiated interaction coefficient 1·024, 95% CI 0·997 to 1·052, p=0·078). Among women, HIV testing increased quarterly by 10·6% (RC 1·106, 95% CI 1·097 to 1·114, p<0·0001) in the intervention communities and 9·3% (1·093, 1·084 to 1·102, p=0·053) in the control communities; increases were greater in intervention communities (exponentiated interaction coefficient 1·012, 95% CI 1·001 to 1·023, p=0·043). Quarterly linkage increased significantly among women in the intervention communities (RC 1·013, 95% CI 1·002 to 1·023, p=0·018) only. Quarterly linkage fell among men in both arms, but decreased significantly among men in the control communities (0·977, 0·954 to 1·002, p=0·043). Quarterly retention fell among women in both arms; however, reductions were tempered among women in the intervention communities (exponentiated interaction coefficient 1·003, 95% CI <1·000 to 1·006, p=0·062). Retention fell significantly among men in both arms with difference in rates of decline.Interpretation: Community mobilisation was associated with modest improvements in select trial outcomes. The sum of these incremental, quarterly improvements achieved by addressing social barriers to HIV care engagement can impact epidemic control. However, achieving optimal impacts will probably require integrated efforts addressing both social barriers through community mobilisation and provision of improved service delivery.

    • Background: While community mobilization (CM) is a powerful toolto increase and sustain demand for HIV testing services, few rigoroustrials of CM interventions have been conducted. We implementeda theory-driven CM intervention in order to improve HIV outcomesin 22 communities participating in a community randomized trial(CRT) in a rural area of Mpumalanga Province, South Africa. Themobilization activities were designed to improve community collaboration to address HIV and inequitable gender norms.Methods: Cross-sectional surveys were conducted with 5055residents ages 1835 in each village prior to (n=1181; 2012) andfollowing (n=1174; 2014) two years of intensive intervention activities in half of the villages. Intervention activities mapped onto sixdomains of CM: 1) shared concern around HIV, 2) community consciousness, 3) organizational structures, 4) leadership, 5) communitycohesion and 6) collective action. Validated domain measures wereincluded in the surveys and mean community CM scores werecomputed and used to predict HIV testing in the past year for eachdomain and for total CM scores. We used GEE logistic regressionanalysis to assess the effect of village level CM domain scores onindividual-level testing outcomes and included interaction terms toassess intervention effects at follow-up.Results: The overall CM score as well as three of six CM domains,including consciousness, concerns, collective action, were significantlyassociated with HIV testing following the intervention and interactedwith intervention assignment. For example, for every standard deviation increase in community consciousness, the odds of HIV testingincreased for intervention village participants (OR: 1.36, p=<0.01)but not for control village participants. Similar findings for total CMscore (OR: 1.51), shared concerns (OR: 1.62) and collective action (OR:1.45) indicate that the intervention successfully improved HIV testing.Leadership, presence of organizations and community cohesion werenot significantly associated with HIV testing at end line.Conclusions: To our knowledge this is the first CRT assessing atheory-based CM intervention including quantitative measures ofCM domains over time. While not all of the six domains were associated with HIV testing uptake, we found clear evidence that communities can be mobilized and that CM measures are associated withimproved engagement in HIV testing.

    • Background: HIV testing uptake in South Africa is below optimal levels. Community mobilization (CM) may increase and sustain demand for HIV testing, however, little rigorous evidence exists regarding the effect of CM interventions on HIV testing and the mechanisms of action.Methods: We implemented a theory-driven CM intervention in 11 of 22 randomly-selected villages in rural Mpumalanga Province. Cross-sectional surveys including a community mobilization measure were conducted before (n = 1181) and after (n = 1175) a 2-year intervention (2012–2014). We assessed community-level intervention effects on reported HIV testing using multilevel logistic models. We used structural equation models to explore individual-level effects, specifically whether intervention assignment and individual intervention exposure were associated with HIV testing through community mobilization.Results: Reported testing increased equally in both control and intervention sites: the intervention effect was null in primary analyses. However, the hypothesized pathway, CM, was associated with higher HIV testing in the intervention communities. Every standard deviation increase in village CM score was associated with increased odds of reported HIV testing in intervention village participants (odds ratio: 2.6, P = <0.001) but not control village participants (odds ratio: 1.2, P = 0.53). Structural equation models demonstrate that the intervention affected HIV testing uptake through the individual intervention exposure received and higher personal mobilization scores.Conclusions: There was no evidence of community-wide gains in HIV testing due to the intervention. However, a significant intervention effect on HIV testing was noted in residents who were personally exposed to the intervention and who evidenced higher community mobilization. Research is needed to understand whether CM interventions can be diffused within communities over time.

  • Development, validation, and performance of a scale to measure community mobilization
  • 2016

    • Rationale: Community mobilization approaches (CMAs) are increasingly becoming key components of health programming. However, CMAs have been ill defined and poorly evaluated, largely due to the lack of measurement tools to assess mobilization processes and impact. Objective: We developed the Community Mobilization Measure (CMM), composed of a set of scales to measure mobilization domains hypothesized to operate at the community-level. The six domains include: shared concerns, critical consciousness, leadership, collective action, social cohesion, and organizations and networks. We also included the domain of social control to explore synergies with the related construct of collective efficacy. Method: A survey instrument was developed and pilot tested, then revised and administered to 1181 young people, aged 18-35, in a community-based survey in rural South Africa. Item response modeling and exploratory factor analyses were conducted to assess model fit, dimensionality, reliability, and validity. Results: Results indicate the seven-dimensional model, with linked domains but no higher order construct, fit the data best. Internal consistency reliability of the factors was strong, with rho values ranging from 0.81 to 0.93. Six of seven scales were sufficiently correlated to represent linked concepts that comprise community mobilization; social control was less related to the other components. At the village level, CMM sub-scales were correlated with other metrics of village social capital and integrity, providing initial evidence of higher-level validity, however additional evaluation of the measure at the community level is needed. Conclusion: This is the first effort to develop and validate a comprehensive measure for community mobilization. The CMM was designed as an evaluation tool for health programming and should facilitate a more nuanced understanding of mechanisms of change associated with CM, ultimately making mobilizing approaches more effective.

  • Evaluation of the Tsima community mobilization intervention to improve engagement in HIV testing and care in South Africa : study protocol for a cluster randomized trial
  • 2017
  • Ingår i: Implementation Science. - : BIOMED CENTRAL LTD. - 1748-5908. ; 12:9
  • Tidskriftsartikel (refereegranskat)abstract
    • Background: HIV transmission can be decreased substantially by reducing the burden of undiagnosed HIV infection and expanding early and consistent use of antiretroviral therapy (ART). Treatment as prevention (TasP) has been proposed as key to ending the HIV epidemic. To activate TasP in high prevalence countries, like South Africa, communities must be motivated to know their status, engage in care, and remain in care. Community mobilization (CM) has the potential to significantly increase uptake testing, linkage to and retention in care by addressing the primary social barriers to engagement with HIV care-including poor understanding of HIV care; fear and stigma associated with infection, clinic attendance and disclosure; lack of social support; and gender norms that deter men from accessing care. Methods/design: Using a cluster randomized trial design, we are implementing a 3-year-theory-based CM intervention and comparing gains in HIV testing, linkage, and retention in care among individuals residing in 8 intervention communities to that of individuals residing in 7 control communities. Eligible communities include 15 villages within a health and demographic surveillance site (HDSS) in rural Mpumalanga, South Africa, that were not exposed to previous CM efforts. CM activities conducted in the 8 intervention villages map onto six mobilization domains that comprise the key components for community mobilization around HIV prevention. To evaluate the intervention, we will link a clinic-based electronic clinical tracking system in all area clinics to the HDSS longitudinal census data, thus creating an open, population-based cohort with over 30,000 18-49-year-old residents. We will estimate the marginal effect of the intervention on individual outcomes using generalized estimating equations. In addition, we will evaluate CM processes by conducting baseline and endline surveys among a random sample of 1200 community residents at each time point to monitor intervention exposure and community level change using validated measures of CM. Discussion: Given the known importance of community social factors with regard to uptake of testing and HIV care, and the lack of rigorously evaluated community-level interventions effective in improving testing uptake, linkage and retention, the proposed study will yield much needed data to understand the potential of CM to improve the prevention and care cascade. Further, our work in developing a CM framework and domain measures will permit validation of a CM conceptual framework and process, which should prove valuable for community programming in Africa.

  • Village community mobilization is associated with reduced HIV incidence in young South African women participating in the HPTN 068 study cohort
  • 2018
  • Ingår i: Journal of the International AIDS Society. - : John Wiley & Sons. - 1758-2652. ; 21:S7

    • Introduction: Adolescent girls and young women (AGYW) in South Africa bear a disproportionate burden of HIV. Community mobilization (CM), defined as community members taking collective action to achieve a common goal related to health, equity and rights, has been associated with increased HIV testing and condom use and has been called a ‘critical enabler’ for addressing the HIV epidemic. However, limited research has examined whether CM is associated with HIV incidence among AGYW.Methods: We examine the association of CM with incident HIV among AGYW (ages 13 to 21) enrolled in the HPTN 068 cohort in the Agincourt Health and socio‐Demographic Surveillance System, South Africa. This analysis includes 2292 participants residing in 26 villages where cross‐sectional, population‐based surveys were conducted to measure CM among 18‐ to 35‐year‐old residents in 2012 and 2014. HPTN 068 participants completed up to five annual visits that included an HIV test (2011 to 2016). Household‐level data were collected from AGYW parents/guardians and census data is updated annually. Mean village‐level CM scores were created using a validated community mobilization measure with seven components (social cohesion, social control, critical consciousness, shared concerns, organizations and networks, leadership and collective action). We used pooled generalized estimating equation regression with a Poisson distribution to estimate risk ratios (RR) for the association of village‐level CM score and CM components with incident HIV infection, accounting for village‐level clustering and adjusting for key covariates.Results: There were 194 incident infections over the follow‐up period. For every additional standard deviation of village‐level CM there was 12% lower HIV incidence (RR: 0.88, 95% CI: 0.79, 0.98) after adjusting for individual, household and community characteristics. CM components associated with lower HIV incidence included critical consciousness (RR: 0.88; CI: 0.79, 0.97) and leadership (RR: 0.87; CI: 0.79, 0.95); while not statistically significant, social cohesion (RR: 0.91; CI: 0.81, 1.01), shared concerns (RR: 0.90; CI: 0.81, 1.00), and organizations and networks (RR: 0.91; CI: 0.79, 1.03) may also play a protective role.Conclusions: These results suggest that having strong community social resources will reduce AGYW's risk of HIV acquisition. Work to mobilize communities, focusing on building social cohesion, shared concerns, critical consciousness, and effective and accountable leadership, can fortify prevention programming for AGYW.

  • Tidskriftsartikel (refereegranskat)abstract
    • Background: Social grants have been found to have an impact on health and wellbeing in multiple settings. Who receives the grant, however, has been the subject of discussion with regards to how the money is spent and who benefits from the grant.Methods: Using survey data from 1214 young women who were in the intervention arm and completed at least one annual visit in the HPTN 068 trial, and qualitative interview data from a subset of 38 participants, we examined spending of a cash transfer provided to young women conditioned on school attendance.Results: We found that spending was largely determined and controlled by young women themselves and that the cash transfer was predominately spent on toiletries, clothing and school supplies. In interview data, young women discussed the significant role of cash transfers for adolescent identity, specifically with regard to independence from family and status within the peer network. There were almost no negative consequences from receiving the cash transfer.Conclusions: We established that providing adolescents access to cash was not reported to be associated with social harms or negative consequences. Rather, spending of the cash facilitated appropriate adolescent developmental behaviours. The findings are encouraging at a time in which there is global interest in addressing the structural drivers of HIV risk, such as poverty, for young women.

    • Community mobilization has been recognized as a critical enabler for HIV prevention and is employed for challenging gender inequalities. We worked together with community partners to implement the 'One Man Can' intervention in rural Mpumalanga, South Africa to promote gender equality and HIV risk reduction. During the intervention, we conducted longitudinal qualitative interviews and focus group discussions with community mobilizers (n = 26), volunteer community action team members (n = 22) and community members (n = 52) to explore their experience of being part of the intervention and their experiences of change associated with the intervention. The objective of the study was to examine processes of change in community mobilization for gender equity and HIV prevention. Our analysis showed that over time, participants referred to three key elements of their engagement with the intervention: developing respect for others; inter-personal communication; and empathy. These elements were viewed as assisting them in adopting a 'better life' and associated with behaviour change in the intervention's main focus areas of promoting gender equality and HIV risk reduction behaviours. We discuss how these concepts relate to the essential domains contained within our theoretical framework of community mobilization-specifically critical consciousness, shared concerns and social cohesion -, as demonstrated in this community. We interpret the focus on these key elements as significant indicators of communities engaging with the community mobilization process and initiating movement towards structural changes for HIV prevention.

  • Sexual Partner Types and Incident HIV Infection Among Rural South African Adolescent Girls and Young Women Enrolled in HPTN 068 : A Latent Class Analysis
  • 2019
  • Ingår i: Journal of Acquired Immune Deficiency Syndromes. - : LIPPINCOTT WILLIAMS & WILKINS. - 1525-4135 .- 1944-7884. ; 82:1, s. 24-33

    • Background: Sexual partners are the primary source of incident HIV infection among adolescent girls and young women (AGYW) in sub-Saharan Africa. Identifying partner types at greatest risk of HIV transmission could guide the design of tailored HIV prevention interventions. Methods: We conducted a secondary analysis of data from AGYW (aged 13-23 years) enrolled in a randomized controlled trial of cash transfers for HIV prevention in South Africa Annually, AGYW reported behavioral and demographic characteristics of their 3 most recent sexual partners, categorized each partner using prespecified labels, and received HIV testing. We used latent class analysis (LCA) to identify partner types from reported characteristics, and generalized estimating equations to estimate the relationship between both LCA-identified and prespecified partner types and incident HIV infection. Results: Across 2140 AGYW visits, 1034 AGYW made 2968 partner reports and 63 AGYW acquired HIV infection. We identified 5 LCA partner types, which we named monogamous HIV-negative peer partner; one-time protected in-school peer partner; out-ofschool older partner; anonymous out-of-school peer partner; and cohabiting with children in-school peer partner. Compared to AGYW with only monogamous HIV-negative peer partners, AGYW with out-of-school older partners had 2.56 times the annual risk of HIV infection (95% confidence interval: 1.23 to 5.33), whereas AGYW with anonymous out-of-school peer partners had 1.72 times the risk (95% confidence interval: 0.82 to 3.59). Prespecified partner types were not associated with incident HIV. Conclusion: By identifying meaningful combinations of partner characteristics and predicting the corresponding risk of HIV acquisition among AGYW, LCA-identified partner types may provide new insights for the design of tailored HIV prevention interventions.

  • Temporal changes in pneumococcal colonization in a rural African community with high HIV prevalence following routine infant pneumococcal immunization
  • 2013
  • Ingår i: The Pediatric Infectious Disease Journal. - : Ovid Technologies (Wolters Kluwer Health). - 0891-3668 .- 1532-0987. ; 32:11, s. 1270-1278

    • Background: Pneumococcal conjugate vaccine (PCV) immunization of children decreases their risk of nasopharyngeal acquisition of vaccine serotypes. We studied the impact of routine infant PCV immunization alone on the epidemiology of nasopharyngeal pneumococcal colonization among a rural African community with high prevalence of HIV positivity.Methods: Two cross-sectional surveys were undertaken in a rural South African community from May to October 2009 (period 1) and 2011 (period 2). Seven-valent PCV was introduced into the public immunization program for infants in April 2009, without catch-up campaign for older children. Randomly selected households with at least 1 child <2 years of age were recruited. Nasopharyngeal swabs from all consenting household members were obtained for Streptococcus pneumoniae culture and serotyping by Quellung method.Results: The median ages (SD) of children enrolled were 4.32 (SD, 3.4) and 3.80 (SD, 3.4) years in periods 1 and 2, respectively. Overall, the prevalence of vaccine serotype colonization declined from 18.3% (368/2010) in period 1 to 11.4% (418/3659) by period 2 (P < 0.0001). This included reductions (adjusted risk ratio) of 50% [95% confidence interval (95% CI): 0.42-0.59], 34% (95% CI: 0.48-0.92) and 64% (95% CI: 0.18-0.74) in age groups < 2 years, 6-12 years and adults. The prevalence of vaccine serotype colonization among primary caregivers decreased from 10.2% to 5.4% (P <= 0.001) by period 2. The prevalence of nonvaccine serotype colonization increased by 35% (95% CI: 1.17-1.56) among <2-year-old children by period 2, while it declined by 45-54% among adolescents and adults.Conclusions: An indirect effect of PCV7 was realized in a high HIV prevalence setting within 2 years of PCV introduction. The unexpected decline in nonvaccine serotypes colonization among adolescents/adults may indicate lag in replacement colonization by nonvaccine serotypes in this group.

  • Building cooperative learning to address alcohol and other drug abuse in Mpumalanga, South Africa : a participatory action research process
  • 2020
  • Ingår i: Global Health Action. - : Taylor & Francis. - 1654-9716 .- 1654-9880. ; 13:1
  • Tidskriftsartikel (refereegranskat)abstract
    • Background: Alcohol and other drug (AOD) abuse is a major public health challenge disproportionately affecting marginalised communities. Involving communities in the development of responses can contribute to acceptable solutions.Objectives: To: (1) document forms, processes, and contexts of engaging communities to nominate health concerns and generate new knowledge for action; (2) further build participation in the local health system by reflecting on and adapting the process.Methods: PAR was progressed with 48 community stakeholders across three rural villages in the MRC/Wits Agincourt Health and Socio Demographic Surveillance System (HDSS) in Mpumalanga, South Africa. A series of workshops explored community-nominated topics, systematised lived experience into shared accounts and considered actions to address problems identified. Photovoice was also used to generate visual evidence. Narrative and visual data were thematically analysed, situated within practice frameworks, and learning and adaption elicited.Results: AOD abuse was identified as a topic of high priority. It was understood as an entrenched social problem with destructive effects. Biopsychosocial impacts were mapped and related to unemployment, poverty, stress, peer pressure, criminal activity, corruption, and a proliferating number of taverns. Integrated action agendas were developed focussed on demand, supply, and harm reduction underpinned by shared responsibility among community, state, and non-state actors. Community stakeholders appreciated systematising and sharing knowledge, taking active roles, developing new skills in planning and public speaking, and progressing shared accountability processes. Expectations required sensitive management, however.Conclusion: There is significant willingness and capacity among community stakeholders to work in partnership with authorities to address priority health concerns. As a process, participation can help to raise and frame issues, which may help to better inform action and encourage shared responsibility. Broader understandings of participation require reference to, and ultimately transfer of power towards, those most directly affected, developing community voice as continuous processes within social and political environments.

  • Community mobilization to modify harmful gender norms and reduce HIV risk : results from a community cluster randomized trial in South Africa

  • Tidskriftsartikel (refereegranskat)abstract
    • Introduction: Community mobilization (CM) is increasingly recognized as critical to generating changes in social norms and behaviours needed to achieve reductions in HIV. We conducted a CM intervention to modify negative gender norms, particularly among men, in order to reduce associated HIV risk.Methods: Twenty two villages in the Agincourt Health and Socio-Demographic Surveillance Site in rural Mpumalanga, South Africa were randomized to either a theory-based, gender transformative, CM intervention or no intervention. Two cross-sectional, population-based surveys were conducted in 2012 (pre-intervention, n = 600 women; n = 581 men) and 2014 (pos-tintervention, n = 600 women; n = 575 men) among adults ages 18 to 35 years. We used an intent-to-treat (ITT) approach using survey regression cluster-adjusted standard errors to determine the intervention effect by trial arm on gender norms, measured using the Gender Equitable Mens Scale (GEMS), and secondary behavioural outcomes.Results: Among men, there was a significant 2.7 point increase (Beta Coefficient 95% CI: 0.62, 4.78, p = 0.01) in GEMS between those in intervention compared to control communities. We did not observe a significant difference in GEMS scores for women by trial arm. Among men and women in intervention communities, we did not observe significant differences in perpetration of intimate partner violence (IPV), condom use at last sex or hazardous drinking compared to control communities. The number of sex partners in the past 12 months (AOR 0.29, 95% CI 0.11 to 0.77) were significantly lower in women in intervention communities compared to control communities and IPV victimization was lower among women in intervention communities, but the reduction was not statistically significant (AOR 0.53, 95% CI 0.24 to 1.16).Conclusion: Community mobilization can reduce negative gender norms among men and has the potential to create environments that are more supportive of preventing IPV and reducing HIV risk behaviour. Nevertheless, we did not observe that changes in attitudes towards gender norms resulted in desired changes in risk behaviours suggesting that more time may be necessary to change behaviour or that the intervention may need to address behaviours more directly.

    • Young women in South Africa are at high risk for HIV infection. Cash transfers offer promise to reduce HIV risk. We present the design and baseline results from HPTN 068, a phase III, individually randomized trial to assess the effect of a conditional cash transfer on HIV acquisition among South African young women. A total of 2533 young women were randomized to receive a monthly cash transfer conditional on school attendance or to a control group. A number of individual-, partner-, household- and school-level factors were associated with HIV and HSV-2 infection. After adjusting for age, all levels were associated with an increased odds of HIV infection with partner-level factors conveying the strongest association (aOR 3.05 95 % CI 1.84–5.06). Interventions like cash transfers that address structural factors such as schooling and poverty have the potential to reduce HIV risk in young women in South Africa.

  • The effect of a conditional cash transfer on HIV incidence in young women in rural South Africa (HPTN 068) : a phase 3, randomised controlled trial
  • 2016
  • Ingår i: The Lancet Global Health. - : Elsevier. - 2214-109X. ; 4:12, s. e978-e988
  • Tidskriftsartikel (refereegranskat)abstract
    • Background: Cash transfers have been proposed as an intervention to reduce HIV-infection risk for young women in sub-Saharan Africa. However, scarce evidence is available about their effect on reducing HIV acquisition. We aimed to assess the effect of a conditional cash transfer on HIV incidence among young women in rural South Africa.Methods: We did a phase 3, randomised controlled trial (HPTN 068) in the rural Bushbuckridge subdistrict in Mpumalanga province, South Africa. We included girls aged 13–20 years if they were enrolled in school grades 8–11, not married or pregnant, able to read, they and their parent or guardian both had the necessary documentation necessary to open a bank account, and were residing in the study area and intending to remain until trial completion. Young women (and their parents or guardians) were randomly assigned (1:1), by use of numbered sealed envelopes containing a randomisation assignment card which were numerically ordered with block randomisation, to receive a monthly cash transfer conditional on school attendance (≥80% of school days per month) versus no cash transfer. Participants completed an Audio Computer-Assisted Self-Interview (ACASI), before test HIV counselling, HIV and herpes simplex virus (HSV)-2 testing, and post-test counselling at baseline, then at annual follow-up visits at 12, 24, and 36 months. Parents or guardians completed a Computer-Assisted Personal Interview at baseline and each follow-up visit. A stratified proportional hazards model was used in an intention-to-treat analysis of the primary outcome, HIV incidence, to compare the intervention and control groups. This study is registered at ClinicalTrials.gov (NCT01233531).Findings: Between March 5, 2011, and Dec 17, 2012, we recruited 10 134 young women and enrolled 2537 and their parents or guardians to receive a cash transfer programme (n=1225) or not (control group; n=1223). At baseline, the median age of girls was 15 years (IQR 14–17) and 672 (27%) had reported to have ever had sex. 107 incident HIV infections were recorded during the study: 59 cases in 3048 person-years in the intervention group and 48 cases in 2830 person-years in the control group. HIV incidence was not significantly different between those who received a cash transfer (1·94% per person-years) and those who did not (1·70% per person-years; hazard ratio 1·17, 95% CI 0·80–1·72, p=0·42).Interpretation: Cash transfers conditional on school attendance did not reduce HIV incidence in young women. School attendance significantly reduced risk of HIV acquisition, irrespective of study group. Keeping girls in school is important to reduce their HIV-infection risk.Funding: National Institute of Allergy and Infectious Diseases, National Institute of Mental Health of the National Institutes of Health.

  • Examining the relationships between body image, eating attitudes, BMI, and physical activity in rural and urban South African young adult females using structural equation modeling
  • 2017
  • Ingår i: PLOS ONE. - : PUBLIC LIBRARY SCIENCE. - 1932-6203. ; 12:11
  • Tidskriftsartikel (refereegranskat)abstract
    • The persistence of food insecurity, malnutrition, increasing adiposity, and decreasing physical activity, heightens the need to understand relationships between body image satisfaction, eating attitudes, BMI and physical activity levels in South Africa. Females aged 18-23 years were recruited from rural (n = 509) and urban (n = 510) settings. Body image satisfaction was measured using Stunkard's silhouettes, and the 26-item Eating Attitudes questionnaire (EAT-26) was used to evaluate participants' risk of disordered eating. Minutes per week of moderate to vigorous physical activity (MVPA) was assessed using the Global Physical Activity Questionnaire (GPAQ). Significant linear correlates were included in a series of regressions run separately for urban and rural participants. Structural equation modeling (SEM) was used to test the relationships between variables. Urban females were more likely to be overweight and obese than rural females (p = 0.02), and had a greater desire to be thinner (p = 0.02). In both groups, being overweight or obese was positively associated with a desire to be thinner (p<0.01), and negatively associated with a desire to be fatter (p<0.01). Having a disordered eating attitude was associated with body image dissatisfaction in the urban group (beta = 1.27, p<0.01, CI: 0.38; 2.16), but only with a desire to be fatter in the rural group (beta = 0.63, p = 0.04, CI: 0.03; 1.23). In the SEM model, body image dissatisfaction was associated with disordered eating (beta = 0.63), as well as higher MVPA participation (p<0.01). These factors were directly associated with a decreased risk of disordered eating attitude, and with a decreased desire to be thinner. Findings indicate a shift in both settings towards more Westernised ideals. Physical activity may provide a means to promote a healthy body image, while reducing the risk of disordered eating. Given the high prevalence of overweight and obesity in both rural and urban women, this study provides insights for future interventions aimed at decreasing adiposity in a healthy way.

  • Sleep and BMI in South African urban and rural, high and low-income preschool children
  • 2021
  • Ingår i: BMC Public Health. - : Springer Science and Business Media LLC. - 1471-2458. ; 21:1
  • Tidskriftsartikel (refereegranskat)abstract
    • Background: The extent to which income setting or rural and urban environments modify the association between sleep and obesity in young children is unclear. The aims of this cross-sectional observational study were to (i) describe and compare sleep in South African preschool children from rural low-income (RL), urban low-income (UL) and urban high-income (UH) settings; and (ii) test for associations between sleep parameters and body mass index (BMI).Methods: Participants were preschoolers (5.2 ± 0.7y, 49.5% boys) from RL (n = 111), UL (n = 65) and UH (n = 22) settings. Height and weight were measured. Sleep, sedentary behaviour and physical activity were assessed using accelerometery.Results: UL children had higher BMI z-scores (median: 0.39; interquartile range: − 0.27, 0.99) than the UH (− 0.38; − 0.88, 0.11) and RL (− 0.08; − 0.83, 0.53) children (p = 0.001). The UL children had later bedtimes (p < 0.001) and wake-up times (p < 0.001) and shorter 24 h (p < 0.001) and nocturnal (p < 0.001) sleep durations than the RL and UH children. After adjusting for age, sex, setting, SB and PA, for every hour less sleep obtained (24 h and nocturnal), children were 2.28 (95% CI: 1.28–4.35) and 2.22 (95% CI: 1.27–3.85) more likely, respectively, to belong to a higher BMI z-score quartile.Conclusions: Shorter sleep is associated with a higher BMI z-score in South African preschoolers, despite high levels of PA, with UL children appearing to be particularly vulnerable.

  • Young women's perceptions of transactional sex and sexual agency : a qualitative study in the context of rural South Africa
  • 2017
  • Ingår i: BMC Public Health. - : Springer Science and Business Media LLC. - 1471-2458. ; 17
  • Tidskriftsartikel (refereegranskat)abstract
    • Background: Evidence shows that HIV prevalence among young women in sub-Saharan Africa increases almost five-fold between ages 15 and 24, with almost a quarter of young women infected by their early-to mid-20s. Transactional sex or material exchange for sex is a relationship dynamic that has been shown to have an association with HIV infection.Methods: Using five focus group discussions and 19 in-depth interviews with young women enrolled in the HPTN 068 conditional cash transfer trial (2011–2015), this qualitative study explores young women’s perceptions of transactional sex within the structural and cultural context of rural South Africa. The analysis also considers the degree to which young women perceive themselves as active agents in such relationships and whether they recognise a link between transactional sex and HIV risk.Results: Young women believe that securing their own financial resources will ultimately improve their bargaining position in their sexual relationships, and open doors to a more financially independent future. Findings suggest there is a nuanced relationship between sex, love and gifts: money has symbolic meaning, and money transfers, when framed as gifts, indicates a young woman’s value and commitment from the man. This illustrates the complexity of transactional sex; the way it is positioned in the HIV literature ignores that “exchanges” serve as fulcrums around which romantic relationships are organised. Finally, young women express agency in their choice of partner, but their agency weakens once they are in a relationship characterised by exchange, which may undermine their ability to translate perceived agency into STI and HIV risk reduction efforts.Conclusions: This research underscores the need to recognise that transactional sex is embedded in adolescent romantic relationships, but that certain aspects make young women particularly vulnerable to HIV. This is especially true in situations of restricted choice and circumscribed employment opportunities. HIV prevention educational programmes could be coupled with income generation trainings, in order to leverage youth resilience and protective skills within the confines of difficult economic and social circumstances. This would provide young women with the knowledge and means to more successfully navigate safer sexual relationships.

  • Evidence for sample selection effect and Hawthorne effect in behavioural HIV prevention trial among young women in a rural South African community
  • 2018
  • Ingår i: BMJ Open. - : BMJ Publishing Group Ltd. - 2044-6055. ; 8:1
  • Tidskriftsartikel (refereegranskat)abstract
    • Objectives: We examined the potential influence of both sample selection effects and Hawthorne effects in the behavioural HIV Prevention Trial Network 068 study, designed to examine whether cash transfers conditional on school attendance reduce HIV acquisition in young South African women. We explored whether school enrolment among study participants differed from the underlying population, and whether differences existed at baseline (sample selection effect) or arose during study participation (Hawthorne effect).Methods: We constructed a cohort of 3889 young women aged 11-20 years using data from the Agincourt Health and socio-Demographic Surveillance System. We compared school enrolment in 2011 (trial start) and 2015 (trial end) between those who did (n=1720) and did not (11=2169) enrol in the trial. To isolate the Hawthorne effect, we restricted the cohort to those enrolled in school in 2011.Results: In 2011, trial participants were already more likely to be enrolled in school (99%) compared with non-participants (93%). However, this association was attenuated with covariate adjustment (adjusted risk difference (aRD) (95% Cl): 2.9 (0.7 to 6.5)). Restricting to those enrolled in school in 2011, trial participants were also more likely to be enrolled in school in 2015 (aRD (95% Cl): 4.9 (1.5 to 8.3)). The strength of associations increased with age.Conclusions: Trial participants across both study arms were more likely to be enrolled in school than nonparticipants. Our findings suggest that both sample selection and Hawthorne effects may have diminished the differences in school enrolment between study arms, a plausible explanation for the null trial findings. The Hawthorne-specific findings generate hypotheses for how to structure school retention interventions to prevent HIV.

  • Relationship between Receipt of a Social Protection Grant for a Child and Second Pregnancy Rates among South African Women : A Cohort Study
  • 2015
  • Ingår i: PLOS ONE. - : Public Library of Science (PLoS). - 1932-6203. ; 10:9
  • Tidskriftsartikel (refereegranskat)abstract
    • Background Social protection programs issuing cash grants to caregivers of young children may influence fertility. Grant-related income could foster economic independence and/or increase access to job prospects, education, and health services, resulting in lower pregnancy rates. In the other direction, these programs may motivate family expansion in order to receive larger grants. Here, we estimate the net effect of these countervailing mechanisms among rural South African women. Methods We constructed a retrospective cohort of 4845 women who first became eligible for the Child Support Grant with the birth of their first child between 1998 and 2008, with data originally collected by the Agincourt Health and Socio- Demographic Surveillance System in Mpumalanga province, South Africa. We fit Cox regression models to estimate the hazard of second pregnancy in women who reported grant receipt after birth of first child, relative to non- recipients. As a secondary analysis to explore the potential for grant loss to incentivize second pregnancy, we exploited a natural experiment created by a 2003 expansion of the program's age eligibility criterion from age seven to nine. We compared second pregnancy rates between (i) women with children age seven or eight in 2002 (recently aged out of grant eligibility) to (ii) women with children age seven or eight in 2003 (remained grant-eligible). Results The adjusted hazard ratio for the association between grant exposure and second pregnancy was 0.66 (95% CI: 0.58, 0.75). Women with first children who aged out of grant eligibility in 2002 had similar second pregnancy rates to women with first children who remained grant-eligible in 2003 [IRR (95% CI): 0.9 (0.5, 1.4)]. Conclusions Across both primary and secondary analyses, we found no evidence that the Child Support Grant incentivizes pregnancy. In harmony with South African population policy, receipt of the Child Support Grant may result in longer spacing between pregnancies.

  • The Relationship between Alcohol Outlets, HIV Risk Behavior, and HSV-2 Infection among South African Young Women : A Cross-Sectional Study
  • 2015
  • Ingår i: PLOS ONE. - : Public Library of Science (PLoS). - 1932-6203. ; 10:5
  • Tidskriftsartikel (refereegranskat)abstract
    • Background: Alcohol consumption has a disinhibiting effect that may make sexual risk behaviors and disease transmission more likely. The characteristics of alcohol- serving outlets (e.g. music, dim lights, lack of condoms) may further encourage risky sexual activity. We hypothesize that frequenting alcohol outlets will be associated with HIV risk.Methods: In a sample of 2,533 school- attending young women in rural South Africa, we performed a cross- sectional analysis to examine the association between frequency of alcohol outlet visits in the last six months and four outcomes related to HIV risk: number of sex partners in the last three months, unprotected sex acts in the last three months, transactional sex with most recent partner, and HSV- 2 infection. We also tested for interaction by alcohol consumption.Results: Visiting alcohol outlets was associated with having more sex partners [adjusted odds ratio (aOR), one versus zero partners (95% confidence interval (CI)): 1.51 (1.21, 1.88)], more unprotected sex acts [aOR, one versus zero acts ( 95% CI): 2.28 ( 1.52, 3.42)], higher levels of transactional sex [aOR ( 95% CI): 1.63 ( 1.03, 2.59)], and HSV-2 infection [aOR ( 95% CI): 1.30 ( 0.88, 1.91)]. In combination with exposure to alcohol consumption, visits to alcohol outlets were more strongly associated with all four outcomes than with either risk factor alone. Statistical evidence of interaction between alcohol outlet visits and alcohol consumption was observed for all outcomes except transactional sex.Conclusions: Frequenting alcohol outlets was associated with increased sexual risk in rural South African young women, especially when they consumed alcohol. Sexual health interventions targeted at alcohol outlets may effectively reach adolescents at high risk for sexually transmitted infections like HIV and HSV-2.

    • Objective: School attendance prevents HIV and herpes simplex virus-2 (HSV-2) in adolescent girls and young women, but the mechanisms to explain this relationship remain unclear. Our study assesses the extent to which characteristics of sex partners, partner age, and number mediate the relationship between attendance and risk of infection in adolescent girls and young women in South Africa.Design: We use longitudinal data from the HIV Prevention Trials Network 068 randomized controlled trial in rural South Africa, where girls were enrolled in early adolescence and followed in the main trial for more than 3 years. We examined older partners and the number of partners as possible mediators.Methods: We used the parametric g-formula to estimate 4-year risk differences for the effect of school attendance on the cumulative incidence of HIV/HSV-2 overall and the controlled direct effect (CDE) for mediation. We examined mediation separately and jointly for the mediators of interest.Results: We found that young women with high attendance in school had a lower cumulative incidence of HIV compared with those with low attendance (risk difference = -1.6%). Partner age difference (CDE = -1.2%) and the number of partners (CDE = -0.4%) mediated a large portion of this effect. In fact, when we accounted for the mediators jointly, the effect of schooling on HIV was almost removed, showing full mediation (CDE = -0.3%). The same patterns were observed for the relationship between school attendance and cumulative incidence of HSV-2 infection.Conclusion: Increasing school attendance reduces the risk of acquiring HIV and HSV-2. Our results indicate the importance of school attendance in reducing partner number and partner age difference in this relationship.

We tested a structural equation model where individual household and community education measures were associated directly and indirectly with incident HSV-2 through HIV knowledge, future aspirations, age-disparate partnerships, sex in the last 12 months, and condomless sex.Results: Community, household, and individual measures of schooling were all associated with incident HSV-2 infection through mediated pathways that increased the likelihood of having sex. Low school attendance (<80% of school days) increased the likelihood of having sex through increased age-disparate partnerships and reduced future aspirations. Fewer community years of education increased the likelihood of having sex through increased age-disparate partnerships. Parental education level was indirectly associated with HSV-2 overall, although we could not identify the individual pathways that were responsible for this association.Conclusions: Community and individual schooling interventions may reduce the risk of HSV-2 infection by influencing the likelihood of having sex, partner age, and future aspirations.

    • Objective: To estimate the association between school attendance, school dropout, and risk of incident HIV and herpes simplex virus type 2 (HSV-2) infection among young women.Design: We used longitudinal data from a randomized controlled trial in rural Mpumalanga province, South Africa, to assess the association between school days attended, school dropout, and incident HIV and HSV-2 in young women aged 13-23 years.Methods: We examined inverse probability of exposure weighted survival curves and used them to calculate 1.5, 2.5, and 3.5-year risk differences and risk ratios for the effect of school attendance on incident HIV and HSV-2. A marginal structural Cox model was used to estimate hazard ratios for the effect of school attendance and school dropout on incident infection.Results: Risk of infection increased over time as young women aged, and was higher in young women with low school attendance (<80% school days) compared with high (>= 80% school days). Young women with low attendance were more likely to acquire HIV [hazard ratio (HR): 2.97; 95% confidence interval (CI): 1.62, 5.45] and HSV-2 (HR: 2.47; 95% CI: 1.46, 4.17) over the follow-up period than young women with high attendance. Similarly, young women who dropped out of school had a higher weighted hazard of both HIV (HR 3.25 95% CI: 1.67, 6.32) and HSV-2 (HR 2.70; 95% CI 1.59, 4.59).Conclusion: Young women who attend more school days and stay in school have a lower risk of incident HIV and HSV-2 infection. Interventions to increase frequency of school attendance and prevent dropout should be promoted to reduce risk of infection.

  • The effects of a cash transfer intervention on sexual partnerships and HIV in the HPTN 068 study in South Africa
  • 2020
  • Ingår i: Culture, Health and Sexuality. - : Taylor & Francis. - 1369-1058 .- 1464-5351. ; 22:10, s. 1112-1127
  • Tidskriftsartikel (refereegranskat)abstract
    • Evidence on cash transfer interventions for HIV prevention in adolescent girls and young women is unclear and indicates that they may not work uniformly in all settings. Qualitative interviews were conducted with 22 girls and young women post-intervention to determine how a cash transfer study (HPTN 068) in South Africa was perceived to influence sexual behaviours and to explore mechanisms for these changes. Participants described how the intervention motivated them to increase condom use, have fewer partners, end risky relationships and access HIV testing services at local primary health clinics. Changes were attributed to receipt of the cash transfer, in addition to HIV testing and sexual health information. Processes of change included improved communication with partners and increased negotiation power in sexual decision-making. Economic empowerment interventions increase confidence in negotiating behaviours with sexual partners and are complementary to sexual health information and health services that provide young women with a foundation on which to make informed decisions about how to protect themselves.
