- 2018
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Background: Cancer is a major public health problem globally. The incidence of cancer is increasing rapidly in many low- and middle-income countries like India due to the epidemiological transition. At present, breast cancer is the leading cancer in females in many countries including India. In spite of all of the epidemiological evidence pointing towards a surge in breast cancer cases, the National Cancer Control Programme of India has not yet taken sufficient measures to understand the disease burden and to plan a course of action to cope with the increasing cancer burden. Aim: The aim of this thesis is to explore the knowledge, attitudes, and practices regarding breast cancer in a predominantly rural district of central India along with identifying the determinants of delays to care and quality of life (QoL) in breast cancer patients. This understanding may help to strengthen the health system by improving breast cancer control and management programmes and the delivery of care.Methods: This thesis combines findings from two cross-sectional studies in the predominantly rural district of Wardha. The first study was a population-based crosssectional survey conducted on 1000 women, in which face-to-face interviews were conducted with the help of a questionnaire covering demographic and socio-economic information, knowledge, attitudes and practices regarding breast cancer screening and breast cancer. The Chi-square test for proportions and t-test for means were used and multivariable linear regression analysis was performed to study the association between socio-demographic factors and knowledge, attitude and practices. The second study was a patient-based cross-sectional study conducted in 212 breast cancer patients. All 212 breast cancer patients were included for patient delay. However, 208 female breast cancer patients could be included for system delay, quality of life and self-efficacy, as there was some information lacking in 4 patients. Information on socio-demographic characteristics, patient and system delays and also reasons for the delays were collected. The study also utilised WHOQOL–BREF for QoL and selfefficacy measurements in breast cancer patients. Socio-demographic determinants were examined by frequencies and means and multivariable logistic and linear regression analysis to assess the relationship between exposure and outcome variables.Results: One third of the respondents had not heard about breast cancer, and more than 90% of women from both rural and semi-urban areas were not aware of breast self-examination. Patient delay of more than 3 months was observed in almost half of participants, while a system delay of more than 12 weeks was seen in 23% of the breast cancer patients. The late clinical stage of the disease was also significantly associated with patient delay. The most common reason for patient delay was painlessness of the breast lump. Incorrect initial diagnosis or late reference for diagnosis were the most common reasons for diagnostic delay while the high cost of treatment was the most common reason for treatment delay. Self-efficacy was positively associated with QoL, after adjusting for socio-demographic factors, patient delay and clinical stage of disease.Conclusions: Our research showed poor awareness and knowledge about breast cancer, its symptoms and risk factors in women in rural India. Breast self-examination was hardly practiced, although the willingness to learn was high. Although The ideal is to have no delay in diagnosis and treatment, diagnostic and treatment delays observed in the study were not much higher than those reported in the literature, even from countries with good health facilities. However, further research is needed to identify access barriers throughout the process of cancer diagnosis and treatment. The quality of life was moderately good and its strong relationship with self-efficacy makes these two dimensions of breast cancer patients relevant enough to be considered for health workers and policy makers in the future.Interventions focused on improving breast awareness in women and the breast cancer continuum of care should be implemented at a district level. The role of community social health activists in breast cancer prevention should be encouraged and the implementation of an operational national breast cancer program is urgently required.

Social capital and well-being in the transitional setting of Ukraine
- 2017
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Background: The military conflict in Ukraine that started in 2014 was accompanied with many changes in the political, economic and social spheres. It brought informal volunteering activities (i.e. one form of social capital) to emerge, function and later to be formalized, in order to support soldiers and their families. This situation is unique given the transitional setting of Ukraine, which has led to comparably low levels of social capital and negative indicators of health and well-being. This thesis aims to explore social capital during military conflict in contemporary Ukraine and to analyze the associations between social capital and well-being, as well as the distribution of social capital among Ukrainian women and men.Methods: The study combines a qualitative and quantitative research design. A case study was conducted using qualitative methodology. Eighteen in-depth interviews were collected with providers and utilizers of volunteering services. Grounded Theory and social action ideal types methodology of Weber were used for the analysis. The quantitative research utilized two secondary datasets. The World Health Survey was utilized to analyze the association between social capital and physical and mental well-being for women (n=1723) and men (n=910) by means of multivariate logistic regression. The European Social Survey (wave 6) was used in order to investigate access to social capital and the determinants of gender inequalities in the access with a sample of 1377 women and 797 men. Multivariate logistic regression and postregression Fairlie’s decomposition analysis were used to analyze the determinants of the inequalities.Results: The key findings of this thesis show that social capital transforms during military conflict and takes particular forms in transitional settings. There are positive and negative effects on well-being connected to crisisrelated volunteering. The associations between social capital and well-being vary for women and men in favour of women. Social capital is unequally distributed between different social groups. Some forms of social capital may have stronger buffering effect on women than men in Ukraine. Access to social capital can be viewed as an indicator for social well-being, and thus social capital can be used both as a determinant and an outcome in social capital and health research.Conclusion: Informal social participation, i.e. volunteering might play an important role in societal crises and needs to be considered in social capital measurements and interventions. Social capital measurements utilized in stable societies do not evidently capture these forms, i.e. it is not taken into account. The associations between social capital and well-being depend on the measurements that are used. Since social capital has both positive and negative effects on well-being, this should be considered in research, policies and practices in order to prevent negative and promote positive outcomes. In Ukraine, as well as in other settings, social capital is an unequal resource for different societal groups. Reducing gender and income inequalities would probably influence the distribution of social capital within the society.

Inequalities in non-communicable diseases in urban Hanoi, Vietnam : health care utilization, expenditure and responsiveness of commune health stations
- 2016

Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Background: Non-communicable diseases (NCDs) are the leading causes of morbidity and mortality among adults in Vietnam. Little is known about the magnitude of socioeconomic inequalities in NCDs and other NCD-related factors in urban areas, in particular among the poor living in slum areas. Understanding these disparities are essential in contributing to the knowledge, needed to reduce inequalities and close the related health gaps burdening the disadvantaged populations in urban areas. Objective: To examine the burden and health system responsiveness to NCDs in Hanoi, Vietnam and investigate the role of socioeconomic inequalities in their prevalence, subsequent healthcare utilization and related impoverishment due to health expenditures. Methods: A cross-sectional study was conducted among 3,736 individuals aged 15 years and over who lived in 1211 randomly selected households in 2013 in urban Hanoi, Vietnam. The study collected information on household’s characteristics, household expenditures, and household member information. A qualitative approach was implemented to explore the responsiveness of commune health stations to the increasing burden of NCDs in urban Hanoi. In-depth interview approach was conducted among health staff involved in NCD tasks at four commune health stations in urban Hanoi. Furthermore, NCD managers at relevance district, provincial and national levels were interviewed. Results: The prevalence of self-reported NCDs was significantly higher among individuals in non-slum areas (11.6%) than those in slum areas (7.9%). However, the prevalence of self-reported NCDs concentrated among the poor in both slum and non-slum areas. In slum areas, the poor needed more health care services, but the rich consumed more health care services. Among households with at least one household member reporting diagnosis of NCDs, the proportion of household facing catastrophic health expenditure and impoverishment were the greater in slum areas than in non-slum areas. Poor households in slum areas were more likely to face catastrophic health expenditure and impoverishment. The poor in non-slum areas were also more likely to face impoverishment if their household members experienced NCDs. Health system responses to NCDs at commune health stations in urban Hanoi were weak, characterized by the lack of health information, inadequate human resources, poor financing, inadequate quality and quantity of services, lack of essential medicines. The commune health stations were not prepared to respond to the rising prevalence of NCDs in urban Hanoi. Conclusion: This thesis shows the existence of socioeconomic inequalities in the prevalence of self-reported NCDs in both non-slum and slum areas in urban Hanoi. NCDs associated with the inequalities in health care utilization, catastrophic health expenditure and impoverishment, particular in slum areas. Appropriate interventions should focus more on specific population groups to reduce the socioeconomic inequalities in the NCD prevalence and health care utilization related to NCDs to prevent catastrophic health expenditure and impoverishment among the households of NCD patients. The functions of commune health stations in the urban setting should be strengthened through the development of NCDs service packages covered by the health insurance.

Air pollution in Nairobi slums : sources, levels and lay perceptions
- 2017
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- BackgroundAir quality in Africa has remained a relatively under-researched field. Most of the African population is dependent on biomass for cooking and heating, with most of the combustion happening in low efficiency stoves in unvented kitchens. The resulting high emissions are compounded by ingress from poor outdoor air in a context of poor emissions controls. The situation is dire in slum households where homes are crowded and space is limited, pushing households to cook in the same room that is used for sleeping. This study assessed the levels of particulate matter with aerodynamic diameter £ 2.5 microns (PM2.5) in slum households and people's perceptions of and attitudes towards air pollution and health risks of exposure in two slum areas, Viwandani and Korogocho, in the Nairobi city.Methods The study employed both qualitative and quantitative methods. For the quantitative study, we used structured questionnaires to collect data about the source of air pollution among adults aged 18 years and above and pregnant women residing in the two study communities. We used the DustTrak™ air samplers to monitor the indoor PM2.5 levels in selected households. We also collected data on community perceptions on air pollution, annoyance and associated health risks. We presented hotspot maps to portray the spatial distribution of perceptions on air pollution in the study areas. For the qualitative study, we conducted focus group discussions with adult community members. Groups were disaggregated by age to account for different languages used to communicate with the younger and older people. We analysed the qualitative data using thematic analysis.Results Household levels of PM2.5 varied widely across households and ranged from 1 to 12,369μg/m3 (SD=287.11). The household levels of PM2.5 levels were likely to exceed the WHO guidelines given the high levels observed in less than 24 hours of monitoring periods (on average 10.4 hours in Viwandani and 11.8 hours in Korogocho). Most of the respondents did not use ventilation use in the evening which coincided with the use of cookstove and lamp, mostly burning kerosene. The levels of PM2.5 varied by the type of fuels, with the highest emissions in households using kerosene for cooking and lighting. The PM2.5 levels spiked in the evenings and during periods of cooking using charcoal/wood. Despite these high levels, residents perceived indoor air to be less polluted compared with the outdoor air, possibly due to the presence of large sources of emissions near the communities such as dumpsites and industries. The community had mixed perceptions on the health impacts of air pollution, with respiratory illnesses perceived as the main consequence while vector or sanitation related diseases such as diarrhoea was also perceived to be related to air pollution.ConclusionsWith poor housing and reliance on dirty fuels, households in slums face potentially high levels of exposure to PM2.5 with dire implications on health. To address the poor perception on air pollution and knowledge gaps on the health effects of air pollution, education programs need to be developed and tailored. These programs should aim to provide residents with information on air quality and its impact on the health; what they can do as communities as well as empower them to reach out to government/stakeholders for action on outdoor sources of pollution such as emissions from dumpsites or industries. The government has a larger role in addressing some of the key pollution sources through policy formulation and strong implementation/enforcement.

Abdominal obesity among older population in Indonesia : socioeconomic and gender inequality, pattern and impacts on disability and death
- 2018
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Background: Population ageing has contributed to the rise of chronic non-communicable diseases (NCDs). Concurrently, obesity prevalence is increasing in all age groups and has become a serious public health problem. Obesity is the main risk factors of the major chronic NCDs such as type 2 diabetes and has been linked to disability and mortality. Studies of socioeconomic inequalities in obesity among older people in Indonesia are scarce. Understanding socioeconomic inequalities are essential to develop appropriate health programme to improve the population health. This thesis describes the pattern of socioeconomic and gender inequality in abdominal obesity and analyses its impact on disability and all-cause mortality among older people in Indonesia.Methods: This thesis is based on four studies conducted in Purworejo Health and Demographic Surveillance System (HDSS) site in Purworejo district, Central Java, Indonesia. This thesis uses both quantitative and qualitative methods. The qualitative study (sub-study 1) was based on 12 Focus Group Discussions (FGDs) with 68 participants from different age groups, sex, and living area. Content analysis was used to describe the community perceptions on diabetes and its risk factors. The quantitative studies (sub-study 2 to 4) utilized longitudinal panel data from the 1st (n = 11,753 individuals) and 2nd wave (n = 14,235 individuals) of the WHO-INDEPTH Study on global AGEing and adult health (SAGE) conducted among all individuals aged 50 years and older in 2007 and 2010. Sub-study 2 used concentration index and decomposition analysis to analyse the pattern of socioeconomic and gender inequality in abdominal obesity. Sub-study 3 used linear regression to examine the association between abdominal obesity and disability. Sub-study 4 used Cox regression analysis with restricted cubic splines to examine the impact of abdominal obesity on all-cause mortality.Results: The FGDs reveals that the community holds unrealistic optimism in perceiving diabetes its risk factors. The community stated that chronic NCD such as diabetes is caused by modern lifestyles and mostly attacks those who are considered as the wealthy (sub-study 1). Socioeconomic inequality in abdominal obesity exists in Purworejo HDSS. Abdominal obesity was more prevalent among the affluent men and women, with a lesser inequality gaps between rich and poor among women. The main contributing factors to inequalities in abdominal obesity were occupation, wealth index, and education (sub-study 2). In three-year period, the mean waist circumference decreased significantly among the poor. An increase in waist circumference was significantly associated with disability, and the poor people were more disabled compared to the rich (sub-study 3). A U-shaped association was observed between waist circumference and all-cause mortality, particularly among women. This indicated an increased risk of mortality in the lower and upper end of the waist circumference distribution. The poor with low waist circumference had a higher risk of mortality than the rich (sub-study 4).Conclusion: Abdominal obesity was disproportionately more prevalent among older Indonesian women. Though the wealthy people have higher burden of abdominal obesity, the poor people experiences more disability and higher risk of death. Misperception on chronic NCDs and its risk factors exist among the Indonesian population. Abdominal obesity prevention strategies are needed to prevent chronic NCDs, disabilities, and mortality among Indonesian older population. The prevention strategies should be culturally sensitive and address all socioeconomic levels. Special attention should be given to disadvantaged women as the most vulnerable group.

Nutrition transition and the double burden of malnutrition in Indonesia : a mixed method approach exploring social and contextual determinants of malnutrition
- 2017
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- IntroductionNutrition transition concerns the broad changes in the human diet that have occurred over time and space. In low- to middle-income countries such as Indonesia, nutrient transition describes shifts from traditional diets high in cereal and fibre towards Western pattern diets high in sugars, fat, and animal-source foods. This causes a swift increase in the prevalence of overweight and obesity while undernutrition remains a great public health concern. Thus a double burden of malnutrition occurs in the population. The main aim of this investigation was to explore social and contextual determinants of malnutrition in Indonesia. The specific objectives were: (i) to examine body mass index (BMI) changes at the population level, and between and within socioeconomic groups; (ii) to estimate which context (i.e., household or district) has a greater effect on the variation of BMI; (iii) to assess the prevalence of double burden households (defined as the coexistence of underweight and overweight individuals residing in the same household) and its variation among communities as well as its determining factors; and (iv) to explore and understand what contributes to a double burden of malnutrition within a household by focusing on gender relations.MethodsA mixed method approach was adopted in this study. For the quantitative analyses, nationally representative repeated cross-sectional survey data from four Indonesian Family Life Surveys (IFLS; 1993, 1997, 2000, 2007) were used. The IFLS contains information about individual-level, household-level and area-level characteristics. The analyses covered single and multilevel regressions. Data for the qualitative component were collected from sixteen focus group discussions conducted in Central Java and in the capital city Jakarta among 123 rural and urban men and women. Connell’s relational theory of gender and Charmaz’s constructive grounded theory were used to analyse the qualitative data.ResultsGreater increases in BMI were observed at higher percentiles compared to the segment of the population at lower percentiles. While inequalities in mean BMI decreased between socioeconomic groups, within group dispersion increased over time. Households were identified as an important social context in which the variation of BMI increased over time. Ignoring the household level did not change the relative variance contribution of districts on BMI in the contextual analysis. Approximately one-fifth of all households exhibited a double burden of malnutrition. Living in households with a higher socioeconomic status resulted in higher odds of double burden of malnutrition with the exception of women-headed households and communities with high social capital. The qualitative analysis resulted in the construction of three categories: capturing the significance of gendered power relations, the emerging obesogenic environment, and generational relations for child malnutrition.ConclusionAt the population level, greater increases in within-group inequalities imply that growing inequalities in BMI were not merely driven by socioeconomic factors. This suggests that other under-recognised social and contextual factors may have a greater effect on the variation in BMI. At the contextual level, recognition of increased variation among households is important for creating strategies that respond to the differential needs of individuals within the same household. At the household level, women’s empowerment and community social capital should be promoted to reduce inequalities in the double burden of malnutrition across different socioeconomic groups. Ultimately community health and nutrition programmes will need to address gender empowerment and engage men in the fight against the emerging obesogenic environment and increased malnutrition that is evident within households, especially overweight and obesity among children.
