Stigma rises despite antiretroviral roll-out: A longitudinal analysis in South Africa

Stigma is a recognised problem for effective prevention, treatment, and care of HIV/AIDS. However, few studies have measured changes in the magnitude and character of stigma over time. This paper provides the first quantitative evaluation in Africa of the changing nature of stigma and the potential determinants of these changes. More specifically, it evaluates the dynamic relationship between stigma and (1) increased personal contact with people living with HIV/AIDS and (2) knowing people who died of AIDS. Panel survey data collected in Cape town 2003 and 2006 for 1074 young adults aged 14-22 years were used to evaluate changes in three distinct dimensions of stigma: behavioural intentions towards people living with HIV/AIDS; instrumental stigma; and symbolic stigma. Individual fixed effects regression models are used to evaluate factors that influence stigma over time. Each dimension of stigma increased in the population as a whole, and for all racial and gender sub-groups. Symbolic stigma increased the most, followed by instrumental stigma, while negative behavioural intentions showed a modest increase. Knowing someone who died of AIDS was significantly associated with an increase in instrumental stigma and symbolic stigma, while increased personal contact with people living with HIV/AIDS was not significantly associated with any changes in stigma. Despite interventions, such as public-sector provision of antiretroviral treatment (which some hoped would have reduced stigma), stigma increased among a sample highly targeted with HIV-prevention messages. These findings emphasise that changes in stigma are difficult to predict and thus important to monitor. They also indicate the imperative for renewed efforts to reduce stigma, perhaps through interventions to weaken the association between HIV/AIDS and death, to reduce fear of HIV/AIDS, and to recast HIV as a chronic manageable disease.

Attitudes towards people with HIV/AIDS: Stigma and its determinants amongst young adults in Cape Town, South Africa

Abstract HIV/AIDS-related stigma is conceptualised as multi-dimensional, and indices are designed to measure its different dimensions. Findings show that it is uncommon for young adults to have high levels of negative behavioural intentions towards people living with HIV/AIDS, but the majority show some tendencies to discriminate. Expressions of negative judgement (symbolic stigma) and fear of HIV infection (instrumental stigma) are both prevalent. Instrumental stigma is expressed by more respondents and to greater degrees than symbolic stigma. Resource-based stigma, on the other hand, is rare. Understanding of HIV transmission is the most significant (negative) predictor of HIV/AIDS-related stigma, thereby highlighting the importance of HIV/AIDS education campaigns for reducing stigma. The importance of education in general is also indicated by the association of higher levels of education with less instrumental stigma. Symbolic stigma and prejudices towards other groups are also significant (positive) factors predicting negative behavioural intentions and stigmatising attitudes. This suggests that although HIV/AIDS education is necessary for stigma alleviation, it is by no means sufficient. In the case of Cape Town, racial differences are also salient in predicting both the magnitude of HIV/ AIDS-related stigma and its determinants. This corroborates the theory of stigma as a complex social process dependent on particular cultural and environmental contexts. It also highlights the necessity of considering cultural and environmental aspects in understanding and addressing stigma.

Measuring concurrent partnerships: potential for underestimation in UNAIDS recommended method.

Research on concurrent sexual partnerships has been constrained by inconsistent and inaccurate measurements of these partnerships. Recently, a UNAIDS working group recommended a method based on sexual partner histories to improve the measurement of concurrency. Using recent survey data for young adults living in Cape Town, South Africa, we found that this method could result in underestimates of concurrency due to respondents’ failure to report additional sexual partners.

Learning that Circumcision is Protective Against HIV: Risk Compensation Among Men and Women in Cape Town, South Africa

Objectives We examined whether knowledge of the HIV-protective benefits of male circumcision (MC) led to risk compensating behavior in a traditionally circumcising population in South Africa. We extend the current literature by examining risk compensation among women, which has hitherto been unexplored. Methods We used data on Xhosa men and women from the 2009 Cape Area Panel Study. Respondents were asked if they had heard that MC reduces a man’s risk of contracting HIV, about their perceived risk of contracting HIV, and condom use. For each gender group we assessed whether risk perception and condom use differed by knowledge of the protective benefits of MC using bivariate and then multivariate models controlling for demographic characteristics, HIV knowledge/beliefs, and previous sexual behaviors. In a further check for confounding, we used data from the 2005 wave to assess whether individuals who would eventually become informed about the protective benefits of circumcision were already different in terms of HIV risk perception and condom use. Results 34% of men (n = 453) and 27% of women (n = 690) had heard that circumcision reduces a man’s risk of HIV infection. Informed men perceived slightly higher risk of contracting HIV and were more likely to use condoms at last sex (p<0.10). Informed women perceived lower HIV risk (p<0.05), were less likely to use condoms both at last sex (p<0.10) and more generally (p<0.01), and more likely to forego condoms with partners of positive or unknown serostatus (p<0.01). The results were robust to covariate adjustment, excluding people living with HIV, and accounting for risk perceptions and condom use in 2005. Conclusions We find evidence consistent with risk compensation among women but not men. Further attention should be paid to the role of new information regarding MC, and drivers of HIV risk more broadly, in modulating sexual behavior among women.

A cut above the rest: traditional male circumcision and HIV risk among Xhosa men in Cape Town South Africa.

BackgroundRandomized clinical trials have shown that medical male circumcision substantially reduces the risk of contracting HIV. However, relatively little is known about the relationship between traditional male circumcision and HIV risk. This article examines variations in traditional circumcision practices and their relationship to HIV status. MethodsWe used data from the fifth wave of the Cape Area Panel Study (n = 473) of young adults in Cape Town, South Africa, to determine attitudes towards circumcision, whether men were circumcised, at what age, and whether their foreskin had been fully or partially removed. Probit models were estimated to determine the association between extent and age of circumcision and HIV status. ResultsThere was strong support for traditional male circumcision. 92.5% of the men reported being circumcised, with 10.5% partially circumcised. Partially circumcised men had a 7% point greater risk of being HIV positive than fully circumcised men (P < 0.05) and equal risk compared with uncircumcised men. Most (91%) men were circumcised between the ages of 17 and 22 years (mean 19.2 years), and HIV risk increased with age of circumcision (P < 0.10). ConclusionsEfforts should be made to encourage earlier circumcisions and to work with traditional surgeons to reduce the number of partial circumcisions. Data on the extent and age of circumcision are necessary for meaningful conclusions to be drawn from survey data about the relationship between circumcision and HIV status.

Social and cultural contexts of concurrency in a township in Cape Town South Africa.

Understanding the social and cultural context in which concurrent sexual partnerships exist is important, given recent interventions to reduce their prevalence. This qualitative study seeks to improve the understanding of concurrent partnerships and perceptions of the link between concurrency and HIV risk in a South African township in Cape Town. Small-group discussion and focus-group participants reported that concurrency was a common phenomenon in their township. The most commonly cited reasons for participating in concurrent partnerships were material and financial exchange or gain and sexual dissatisfaction with partners. Although participants believed that being in a concurrent relationship increases the risk of acquiring HIV, they did not believe this discourages many people from engaging in these behaviours. This study highlights that concurrency in this context may be a social norm that is resistant to change. The efficacy of current programmes aimed at reducing concurrency needs to be examined in this context. Our findings suggest that improving economic independence at the individual level and improving sexual satisfaction within partnerships may have some leverage for concurrency reduction. An alternative approach to strengthen combination HIV-prevention strategies could be to increase condom use with the additional/side partners, whose predominant role is often perceived in terms of sex, with messages centred on the notion that sex with additional partner(s) should not endanger the main partner.

Social Grants, Welfare, and the Incentive to Trade-Off Health for Income among Individuals on HAART in South Africa

South Africa’s government disability grants are considered important in providing income support to low-income AIDS patients. Indeed, anecdotal evidence suggests that some individuals may opt to compromise their health by foregoing Highly Active Antiretroviral Treatment (HAART) to remain eligible for the grant. In this study, we examined the disability grant’s importance to individual and household welfare, and the impact of its loss using a unique longitudinal dataset of HAART patients in Khayelitsha, Cape Town. We found that grant loss was associated with sizeable declines in income and changes in household composition. However, we found no evidence of individuals choosing poor health over grant loss. Our analysis also suggested that though the grants officially target those too sick to work, some people were able to keep grants longer than expected, and others received grants while employed. This has helped cushion people on HAART, but other welfare measures need consideration.

Sexual Behaviour of Men and Women within Age-Disparate Partnerships in South Africa: Implications for Young Women's HIV Risk.

Background Age-disparate partnerships are hypothesized to increase HIV-risk for young women. However, the evidence base remains mixed. Most studies have focused only on unprotected sex among women in the partnership. Consequently, little is known about other risky behaviours, such as transactional sex, alcohol use, and concurrency, as well as the behaviours of the men who partner with young women. We therefore examined differences in various sexual behaviours of both young women and their male partners by partnership age difference. Methods We used nationally representative data from South Africa (2012) on partnerships reported by 16–24 year old black African women (n = 818) and by black African men in partnerships with 16–24 year old women (n = 985). We compared sexual behaviours in age-disparate partnerships and age-similar partnerships, using multiple logistic regression to control for potential confounders and to assess rural/urban differences. Results Young women in age-disparate partnerships were more likely to report unprotected sex than young women in similar-aged partnerships (aOR:1.51; p = 0.014; 95%CI:1.09–2.11). Men in partnerships with young women were more likely to report unprotected sex (aOR:1.92; p<0.01; 95%CI:1.31–2.81), transactional sex (aOR:2.73; p<0.01; 95%CI:1.64–4.56), drinking alcohol before sex (aOR:1.60; p = 0.062; 95%CI:0.98–2.61), and concurrency (aOR:1.39; p = 0.097; 95%CI:0.94–2.07) when their partners were five or more years younger. The association between age-disparate partnerships and transactional sex (aOR:4.14; p<0.01; 95%CI: 2.03–8.46) and alcohol use (aOR:2.24; p<0.013; 95%CI:1.20–4.19) was only found in urban areas. Conclusions Results provide evidence that young women’s age-disparate partnerships involve greater sexual risk, particularly through the risky behaviours of their male partners, with the risk amplified for young women in urban areas.

Male Circumcision and Sexual Risk Behaviors May Contribute to Considerable Ethnic Disparities in HIV Prevalence in Kenya: An Ecological Analysis

Background HIV prevalence varies between 0.8 and 20.2% in Kenya’s various ethnic groups. The reasons underlying these variations have not been evaluated before. Methods We used data from seven national surveys spanning the period 1989 to 2008 to compare the prevalence of a range of risk factors in Kenya’s ethnic groups. Spearman’s and linear regression were used to assess the relationship between HIV prevalence and each variable by ethnic group. Results The ethnic groups exhibited significant differences in a number of HIV related risk factors. Although the highest HIV prevalence group (the Luo) had the highest rates of HIV testing (Men 2008 survey: 56.8%, 95% CI 51.0–62.5%) and condom usage at last sex (Men 2008∶28.6%, 95% CI 19.6–37.6%), they had the lowest prevalence of circumcision (20.9%, 95% CI 15.9–26.0) the highest prevalence of sex with a non-married, non-cohabiting partner (Men: 40.2%, 95% CI 33.2–47.1%) and pre-marital sex (Men 2008∶73.9%, 95% CI 67.5–80.3%) and the youngest mean age of debut for women (1989 Survey: 15.7 years old, 95% CI 15.2–16.2). At a provincial level there was an association between the prevalence of HIV and male concurrency (Spearman’s rho = 0.79, P = 0.04). Ethnic groups with higher HIV prevalence were more likely to report condom use (Men 2008 survey: R2 = 0.62, P = 0.01) and having been for HIV testing (Men 2008 survey: R2 = 0.47, P = 0.04). Conclusion In addition to differences in male circumcision prevalence, variation in sexual behavior may contribute to the large variations in HIV prevalence in Kenya’s ethnic groups. To complement the prevention benefits of the medical male circumcision roll-out in several parts of Kenya, interventions to reduce risky sexual behavior should continue to be promoted.

Poverty sexual behaviour gender and HIV infection among young black men and women in Cape Town South Africa.

This article contributes methodologically and substantively to the debate over the importance of poverty, sexual behaviour and circumcision in relation to HIV infection, using panel data on young black men and women in Cape Town, South Africa. Methodological challenges included problems of endogeneity and blunt indicator variables, especially for the measurement of sexual behaviour. Noting these difficulties, we found that the importance of socioeconomic and sexual-behavioural factors differed between men and women. While we found a clear association between the number of years of sexual activity and HIV status among both men and women, we found that past participation in a concurrent sexual partnership increased the odds of HIV infection for men but not women. Women, but not men, who made the transition from school to tertiary education (our key indicator of socioeconomic status) were less likely to be HIV-positive than those who made the transition from school to unemployment. Both poverty and sexual behaviour matter to individuals’ HIV risk, but in gendered ways.
