- In Kenya, HIV-1 key populations including men having sex with men (MSM), people who inject drugs (PWID) and female sex workers (FSW) are thought to significantly contribute to HIV-1 transmission in the wider, mostly heterosexual (HET) HIV-1 transmission network. However, clear data on HIV-1 transmission dynamics within and between these groups are limited. We aimed to empirically quantify rates of HIV-1 flow between key populations and the HET population, as well as between different geographic regions to determine HIV-1 'hotspots' and their contribution to HIV-1 transmission in Kenya. We used maximum-likelihood phylogenetic and Bayesian inference to analyse 4058 HIV-1 pol sequences (representing 0.3 per cent of the epidemic in Kenya) sampled 1986-2019 from individuals of different risk groups and regions in Kenya. We found 89 per cent within-risk group transmission and 11 per cent mixing between risk groups, cyclic HIV-1 exchange between adjoining geographic provinces and strong evidence of HIV-1 dissemination from (i) West-to-East (i.e. higher-to-lower HIV-1 prevalence regions), and (ii) heterosexual-to-key populations. Low HIV-1 prevalence regions and key populations are sinks rather than major sources of HIV-1 transmission in Kenya. Targeting key populations in Kenya needs to occur concurrently with strengthening interventions in the general epidemic.

- As rheumatology nursing develops and extends, knowledge about current use of knowledge in rheumatology nursing practice may guide discussions about future knowledge needs. To explore what perceptions rheumatology nurses have about their knowledge sources and about what knowledge they use in their practice, 12 nurses working in specialist rheumatology were interviewed using a semi-structured interview guide. The data were analyzed using conventional qualitative content analysis. The analysis yielded four types of knowledge sources in clinical practice: interaction with others in the workplace, contacts outside the workplace, written materials, and previous knowledge and experience. Colleagues, and physicians in particular, were important for informal learning in daily rheumatology practice. Evidence from the medical arena was accessed through medical specialists, while nursing research was used less. Facilitating informal learning and continuing formal education is proposed as a way toward a more evidence-based practice in extended roles.

- Living alone is increasingly common and has been depicted as an important cause of mortality. We examined the association between living alone and mortality risks among older men and women in northern Sweden, by linking two unique longitudinal datasets.We used the Linnaeus database, which links several population registers on socioeconomic and health. This register-based study included 22,226 men and 23,390 women aged 50 and 60years in Västerbotten County who had participated in the Västerbotten Intervention Program (VIP) during 1990-2006, with a total of 445,823 person-years of observation. We conducted Cox-proportional hazard regression to assess the risk of living alone on the mortality that was observed between 1990 and 2015, controlling for socio-demographic factors, chronic disease risk factors and access to social capital.Older men and women who lived alone with no children at home were at a significantly higher risk of death compared to married/cohabiting couples with children at home (with an adjusted hazard ratio of 1.38, 95% CI of 1.26-1.50 in men and 1.27, 95% CI of 1.13-1.42 in women). Living alone was an even stronger factor than the well-established chronic disease risk factors and a lack of access to social capital.A significant association between living alone and mortality among the older adult population in Sweden was observed. Providing good social support for older people is important in preventing the negative health impact of living alone.

- Introduction: Adolescents and young women in low-middle-income countries face obstacles to accessing HIV, Sexual and Reproductive Health (SRH), and related Gender-Based Violence (GBV) services. This paper presents facilitators, opportunities, and barriers to enhance uptake of HIV, GBV, and SRH services among Adolescent Girls and Young Women (AGYW) in selected districts in Zambia.Methods: This study was conducted in Chongwe, Mazabuka, and Mongu Districts among adolescent girls and young women in Zambia. Key informants (n = 29) and in and out-of-school adolescents and young people (n = 25) were interviewed. Purposive sampling was used to select and recruit the study participants. Interviews were transcribed verbatim, and a content analysis approach was used for analysis.Results: The facilitators that were used to enhance the uptake of services included having access to health education information on comprehensive adolescent HIV and gender-based violence services. Non-governmental organisations (NGOs) were the main source of this information. The opportunities bordered on the availability of integrated approaches to service delivery and strengthened community and health center linkages with referrals for specialised services. However, the researchers noted some barriers at individual, community, and health system levels. Refusal or delay to seek the services, fear of side effects associated with contraceptives, and long distance to the health facility affected the uptake of services. Social stigma and cultural beliefs also influenced the understanding and use of the available services in the community. Health systems barriers were; inadequate infrastructure, low staffing levels, limited capacity of staff to provide all the services, age and gender of providers, and lack of commodities and specialised services.Conclusion: The researchers acknowledge facilitators and opportunities that enhance the uptake of HIV, GBV, and SRH services. However, failure to address barriers at the individual and health systems level always negatively impacts the uptake of known and effective interventions. They propose that programme managers exploit the identified opportunities to enhance uptake of these services for the young population.

Tidskriftsartikel (refereegranskat)abstract
- ABSTRACT: BACKGROUND: Since the Doi Moi reform 1986 economic conditions in Vietnam have changed significantly and positive health and health care developments have been observed. International experience shows that improved economic conditions in a country can reduce the risk of perinatal mortality, decrease the risk of low birth weight and increase the mean birth weight in newborns. The Health and Demographic Surveillance Site (HDSS) FilaBavi in Bavi district outside Hanoi city has been operational since 1999. An open cohort of more than 12,000 households (52,000 persons) has been followed primarily with respect to demography, economy and education. The aim of this research is to study trends in birth weight as well as birth and delivery practices over the time period 1999--2010 in FilaBavi in relation to the social and economic development. METHODS: Information about birth weight, sex, place and method of delivery, mother's age and education as well as household economy of 10,114 children, born from 1999 to 2010, was obtained from the routine data collection in the HDSS. RESULTS: Over the study period the mean birth weight remained at the same level, about 3,100 g, in spite of increased economic resources and technology development. At the individual child level we found associations between birth weight and household economy as well as the education of the mother. Hospital delivery increased from about 35% to 65% and the use of Caesarian section increased from 2.6% to 10.1%. CONCLUSION: During the twelve years studied, household income as well as the use of modern technology increased rapidly. In spite of that, the mean and variation of birth weight did not change systematically. It is suggested that increasing gaps in economic conditions and misallocation of resources, possibly to overuse of technology, are partly responsible.

- BackgroundNearly one-in-two Vietnamese men smoke cigarettes placing them among the highest tobacco consumers in the world. Despite the need for smoking cessation to curb the burden of tobacco-related diseases in Vietnam, this rate remains at less than 30%. Therefore, this study examines individual-, social- and policy factors associated with smoking cessation among adult male smokers in Vietnam.MethodsWe established a longitudinal International Tobacco Control study of male smokers in Hanoi, Vietnam, in September 2018. This paper analyses 1525 men who participated in baseline and one-year follow-up. We applied a weighted multivariable logistic regression to examine the association between smoking cessation and individual-, social- and policy predictors.ResultsAt follow-up, 14.8% of participants had quit smoking for at least 30 consecutive days during the last year. Among the persistent smokers, 56.6% expressed intention to quit smoking. Factors associated with smoking cessation included a lower number of cigarettes smoked per day (aOR = 0.96, 95% CI: 0.94, 0.99) and having several attempts to quit smoking (aOR = 2.16, 95% CI 1.13, 4.12). Intention to quit smoking was associated with multiple quit attempts, a chronic condition diagnosis, more tobacco-related knowledge, greater self-efficacy, and more worries about their future health. The perceived impact of smoke-free policy and health warning labels were positively associated with intention to quit at any stage.ConclusionsInterventions aimed at increasing smoking cessation should focus on all aspects of individual, social, and policy factors. Persistent smokers are more motivated to quit if they have made multiple quit attempts, more self-efficacy of quitting and worried about their future health, indicating that increasing smokers' beliefs and knowledge may be important for behavioural change. Health warning labels and tobacco taxation policies should be maintained and promoted as they are perceived to be particularly useful for persistent smokers' intention to quit.

- Objective: To evaluate the knowledge of nutrition among mothers of children less than two years of age and changes in theoretical knowledge after a nutrition course. Method: A pilot study with a pre-post-test design. Thirty mothers of children who were less than two years of age from outside Hanoi participated in the study. The mothers’ knowledge of breastfeeding, supplementary food and diet when the child was suffering from diarrhea was collected using 19 self-reported questions. A one-day nutrition course at which the mothers answered the same questions before and after the course was run. Results: All the invited mothers were included in the study. There was a lack of knowledge about breastfeeding and nutrition at baseline, but it improved after the nutrition course. The greatest improvement in knowledge related to breastfeeding less than 30 minutes after delivery, not giving milk or fruit juice instead of breast milk, increasing the frequency of breastfeeding in the event of a smaller amount of milk and knowledge about giving supplementary food after six months. Moreover, the results revealed that the mothers reported better knowledge of the consumption and frequency of more healthy food supplements. Conclusion: There was a lack of knowledge about nutrition among the mothers with children less than two years of age. The course demonstrated effectiveness in every aspect of nutritional knowledge, tested in the post-test. The findings in this study could provide important information for authorities in the health sector to improve the nutritional state of children in the community.

Tidskriftsartikel (refereegranskat)abstract
- Mosquito-borne diseases (MBDs) are causing high morbidity and mortality for humans. Urban livestock keeping is still common in cities around the world. The animals may serve as reservoirs for zoonotic MBDs, which increase the risks for humans. Here we assess the knowledge and practices related to MBDs in households with livestock and without livestock and explore the perceptions of the health care sector about MBDs and livestock keeping in Hanoi city of Vietnam in a cross-sectional study. A quantitative survey was conducted including 513 households with and without livestock-keeping in six districts and complemented with qualitative surveys with four health staff from Hanoi Center of Disease Control and three district health centers. The quantitative survey indicated that the participants possessed basic knowledge on MBDs with an average score of 18.3 out of 35, of which non-livestock-keeping households had a better knowledge than households keeping livestock (p<0.05). Both household categories had low score, 3.5 out of 11, regarding preventive practices against MBDs. The negative binomial model showed that occupation and location of living were factors associated to the knowledge on MBDs. Farmers were likely to have better preventive practices as compared to office workers (p<0.05). Those who had better knowledge also had more adequate preventive practices against MBDs (p<0.001). The qualitative survey revealed that livestock keeping was determined as increasing risks of MBDs due to the increase of mosquito population. It is recommended that community campaigns to raise the awareness and change behavior on MBDs should be organized based on collaboration between the health sector and the veterinary sector for households with and without livestock living in central urban and peri-urban areas. Further studies are needed to confirm the association between urban livestock keeping and potential increasing risks of MBDs such as dengue and Japanese encephalitis.

Tidskriftsartikel (refereegranskat)abstract
- Background: Dengue virus and Japanese encephalitis virus are two common flaviviruses that are spread widely by Aedes and Culex mosquitoes. Livestock keeping is vital for cities; however, it can pose the risk of increasing the mosquito population. Our study explored how livestock keeping in and around a large city is associated with the presence of mosquitoes and the risk of them spreading flaviviruses.Methods: An entomological study was conducted in 6 districts with 233 households with livestock, and 280 households without livestock, in Hanoi city. BG-Sentinel traps and CDC light traps were used to collect mosquitoes close to animal farms and human habitats. Adult mosquitoes were counted, identified to species level, and grouped into 385 pools, which were screened for flaviviruses using a pan-flavivirus qPCR protocol and sequencing.Results: A total of 12,861 adult mosquitoes were collected at the 513 households, with 5 different genera collected, of which the Culex genus was the most abundant. Our study found that there was a positive association between livestock keeping and the size of the mosquito population-most predominantly between pig rearing and Culex species (p < 0.001). One pool of Cx. tritaeniorhynchus, collected in a peri-urban district, was found to be positive for Japanese encephalitis virus.Conclusions: The risk of flavivirus transmission in urban areas of Hanoi city due to the spread of Culex and Aedes mosquitoes could be facilitated by livestock keeping.
