Is social capital a useful conceptual tool for exploring community level influences on HIV infection? An exploratory case study from South Africa

Alcohol use and sexual behaviour among risky drinkers and bar and shebeen patrons in Gauteng province, South Africa

This paper describes the South Africa component of a World Health Organization multi-site rapid assessment and response project seeking to develop a methodology for studying factors associated with alcohol use-related sexual risk behaviour in diverse cultural settings. This report focuses on the qualitative assessments that were conducted in order to profile alcohol use and sexual behaviour in the communities concerned, ascertain the relationships between alcohol use and sexual behaviour, and develop a conceptual model of the relationships between alcohol use and sexual risk behaviour. The participants consisted of adults aged between 25 and 44 years in a township and city site in Gauteng province. The assessments involved conducting 18 key informant interviews, observations in seven drinking venues, six focus groups and 16 in-depth interviews of 'risky drinkers' and their partners. Most participants felt that there were high levels of alcohol consumption and unprotected sex among some members of their communities, with the latter occurring mainly among casual sexual partners. The findings also pointed to strong links between alcohol consumption and sexual risk behaviour. A conceptual model of the association between alcohol use and risky sexual behaviour is proposed. This study suggests a need for multi-faceted HIV intervention strategies for reducing levels of alcohol abuse in general, and enhancing protective sexual behaviours among alcohol-using populations.

Communities, opportunities, and adolescents' sexual behavior in KwaZulu-Natal, South Africa

In 2002, the prevalence of HIV among South African clinic attendees under the age of 20 was 15 percent, suggesting a correspondingly high level of unprotected sex and risky sexual behavior. Past research focused on the dynamics of individuals' and partners' sexual decisionmaking without accounting for the larger context in which such decisions are made. Do adolescents' opportunities for schooling, work, and other community activities make a difference? This study uses data collected from a representative sample of young people living in KwaZulu-Natal, South Africa, to explore these questions. Logit analyses show that for girls, higher levels of education reduced the probability of having had sex in the 12 months prior to the survey, and average wages were positively associated with condom use. Greater participation in community sports increased risk-taking behaviors among boys but decreased them among girls. Within the household, education of adults had a positive effect on condom use for both boys and girls.

Community group participation:

The lifetime risk of acquiring HIV infection in many rural as well as urban areas of southern Africa is currently as high as two-in-three. For women, much of this risk still accrues rapidly at young ages despite high levels of knowledge about HIV/AIDS. Thus, programmes that are more participatory and address underlying structural and community-level factors appear to be essential. We use cross-sectional data from a large-scale, population-based survey in rural eastern Zimbabwe to describe the relationships between membership of different forms of community group and young women's chances of avoiding HIV. Our results show that participation in local community groups is often positively associated with successful avoidance of HIV, which, in turn, is positively associated with psychosocial determinants of safer behaviour. However, whether or not these relationships hold depends on a range of factors that include how well the group functions, the purpose of the group, and the education level of the individual participant. We identify factors that may influence the social capital value of community groups in relation to HIV prevention at the individual, group, and community levels. Young women with secondary education participate disproportionately in well-functioning community groups and are more likely to avoid HIV when they do participate. Longitudinal studies are needed: (i) to establish whether community group membership supports the development of safer lifestyles or merely has greater appeal to individuals already predisposed towards such lifestyles, and (ii) to pinpoint directions of causality between hypothesised mediating factors. In-depth research is needed on the specific qualities of community groups that enhance their contribution to HIV control. However, our findings suggest that promotion of and organisational development and training among community groups could well be an effective HIV control strategy.
