HIV-related stigma is a multidimensional concept which has pervasive effects on the lives of HIV-infected people as well as serious consequences for the management of HIV/AIDS. In this research three parallel stigma scales were developed to assess personal views of stigma, stigma attributed to others, and internalised stigma experienced by HIV-infected individuals. The stigma scales were administered in two samples: a community sample of 1,077 respondents and 317 HIV-infected pregnant women recruited at clinics from the same community in Tshwane (South Africa). A two-factor structure referring to moral judgment and interpersonal distancing was confirmed across scales and sample groups. The internal consistency of the scales was acceptable and evidence of validity is reported. Parallel scales to assess and compare different perspectives of stigma provide opportunities for research aimed at understanding stigma, assessing the consequences or evaluating possible interventions aimed at reducing stigma.

To provide understanding of social and psychological factors that affect disclosure of HIV status among women diagnosed HIV-positive in pregnancy, 438 HIV positive women attending antenatal clinics in Pretoria, South Africa were invited to participate in a longitudinal study. A total of 293 (62%) women were enrolled from June 2003 to December 2004. Questionnaires assessing sociodemographics and psychological measures were administered during pregnancy and at 3 months postdelivery. At enrollment, 59% had disclosed to their partners and 42% to others. This rose to 67% and 59%, respectively, by follow-up. Logistic regression analysis identified being married (adjusted odds Ratio [AOR] 2.32; 95% confidence interval [CI] 1.20-4.47), prior discussion about testing (AOR 4.19; CI 2.34-7.49), having a partner with tertiary education (AOR 2.76; CI 1.29-5.88) and less experience of violence (AOR 0.48; CI 0.24-0.97) as factors associated with having disclosed to partners prior to enrollment. Better housing (AOR 1.26; CI 1.06-1.49), less financial dependence on partners (AOR 0.46; CI 0.25-0.85), and knowing someone with HIV (AOR 2.13; CI 1.20-3.76) were associated with prior disclosure to others. Increased levels of stigma at baseline decreased the likelihood of disclosure to partners postenrollment (AOR 0.91; CI 0.84-0.98) and increased levels of avoidant coping decreased subsequent disclosure to others (AOR 0.84; CI 0.72-0.97). These results provide understanding of disclosure for women diagnosed as HIV positive in pregnancy, and identify variables that could be used to screen for women who require help.

Objective To assess the efficacy of an intervention designed to promote resilience in young children living with their HIV-positive mothers. Design/Methods HIV-positive women attending clinics in Tshwane, South Africa and their children, aged 6 - 10 years, were randomised to the intervention (I) or standard care (S). The intervention consisted of 24 weekly group sessions led by community care workers. Mothers and children were in separate groups for 14 sessions, followed by 10 interactive sessions. The primary focus was on parent-child communication and parenting. Assessments were completed by mothers and children at baseline and 6, 12 and 18 months. Repeated mixed linear analyses were used to assess change over time. Results Of 390 mother-child pairs, 84.6% (I:161 & S:169) completed at least two interviews and were included in the analyses. Children's mean age was 8.4 years and 42% of mothers had been ill in the prior three months. Attendance in groups was variable: only 45.7% attended >16 sessions. Intervention mothers reported significant improvements in children's externalizing behaviors (β=-2.8, P=0.002), communication (β=4.3, P=0.025) and daily living skills (β=5.9, P=0.024), while improvement in internalizing behaviors and socialization was not significant (P=0.061 and 0.052 respectively). Intervention children reported a temporary increase in anxiety but did not report differences in depression or emotional intelligence. Conclusions This is the first study demonstrating benefits of an intervention designed to promote resilience among young children of HIV-positive mothers. The intervention was specifically designed for an African context, and has the potential to benefit large numbers of children, if it can be widely implemented

Low 25-hydroxyvitamin D (25(OH)D) concentrations are common among older adults and are associated with poorer physical performance and strength, but results from longitudinal studies have been inconsistent. The 25(OH)D threshold for physical performance and strength was determined, and both cross-sectional and longitudinal associations between 25(OH)D and physical performance and strength were examined, in men and women aged 71-80 years from the Health, Aging, and Body Composition Study (n = 2,641). Baseline serum 25(OH)D was measured in 1998-1999, and physical performance and strength were measured at baseline and at 2- and 4-year follow-up. Piecewise regression models were used to determine 25(OH)D thresholds. Linear regression and mixed models were used to examine cross-sectional and longitudinal associations. The 25(OH)D thresholds were 70-80 nmol/L for physical performance and 55-70 nmol/L for strength. Participants with 25(OH)D <50 nmol/L had poorer physical performance at baseline and at 2- and 4-year follow-up than participants with 25(OH)D ≥75 nmol/L (P < 0.01). Although physical performance and strength declined over 4 years of follow-up (P < 0.0001), in general, the rate of decline was not associated with baseline 25(OH)D. Older adults with low 25(OH)D concentrations had poorer physical performance over 4 years of follow-up, but low 25(OH)D concentrations were not associated with a faster rate of decline in physical performance or strength.

HIV-positive pregnant women often do not disclose their serostatus to their partners, family and friends, creating potential barriers to preventing sexual transmission to partners and mother-to-child transmission through breastfeeding. This research explores recently diagnosed HIV-positive pregnant women’s reasons for disclosure and non-disclosure of serostatus to various members of their social networks, as well as the consequences of their disclosure. Data were collected through open-ended questions as part of a semi-structured interview with 293 recently diagnosed HIV-positive pregnant women recruited from antenatal clinics in two townships in Tshwane, South Africa. A content analysis of responses showed that women weighed fear of abandonment and discrimination against their desire to raise risk awareness and their need for support. Partners most often responded to disclosure with disbelief and shock, whereas parents frequently exhibited emotional distress, but were still supportive, as were other relatives and friends. The women subsequently experienced low levels of adverse consequences after disclosure. The results can assist health care providers in understanding the complexity of pregnant women’s decisions to disclose to various members of their social networks and emphasize the need for continued counselling and support.

The authors of this study evaluated a structured 10-session psychosocial support group intervention for newly HIV-diagnosed pregnant South African women. Participants were expected to display increases in HIV disclosure, self-esteem, active coping and positive social support, and decreases in depression, avoidant coping, and negative social support. Three hundred sixty-one pregnant HIV-infected women were recruited from four antenatal clinics in Tshwane townships from April 2005 to September 2006. Using a quasi-experimental design, assessments were conducted at baseline and two and eight months post-intervention. A series of random effects regression analyses were conducted, with the three assessment points treated as a random effect of time. At both follow-ups, the rate of disclosure in the intervention group was significantly higher than that of the comparison group (p < 0.001). Compared to the comparison group at the first follow-up, the intervention group displayed higher levels of active coping (t = 2.68, p < 0.05) and lower levels of avoidant coping (t = −2.02, p < 0.05), and those who attended at least half of the intervention sessions exhibited improved self-esteem (t = 2.11, p < 0.05). Group interventions tailored for newly HIV positive pregnant women, implemented in resource-limited settings, may accelerate the process of adjusting to one's HIV status, but may not have sustainable benefits over time.

HIV/AIDS-related stigma threatens to undermine interventions to prevent and treat HIV/AIDS. To address stigma in a South African community, a thorough understanding of the nature of stigma in the specific cultural context is needed. The goals of this research were to assess the level of stigmatising attitudes among members of a community, compare this to the level of stigma that is perceived to exist within the community and determine to what extent stigmatising attitudes are affected by socio-demographic characteristics, HIV-related experience and cultural beliefs. A questionnaire was completed by 1077 respondents in key areas in two communities in Tshwane, South Africa. The questionnaire included an assessment of HIV-related experience, HIV-knowledge, personal stigma and perceptions of stigma within the community. The findings indicate that the level of personal stigma was significantly lower than that perceived to be present in the community. Respondents who were more stigmatising were older, male, less educated, and less knowledgeable about HIV. They were less likely to know someone with HIV and had more traditional cultural viewpoints. While socio-demographic and cultural factors are difficult to change, efforts aimed at increasing people’s knowledge and experience of the epidemic occurring in their community could change the level of stigmatising attitudes within their community. Such efforts could have potential benefits in addressing the epidemic and providing greater support for those with HIV.

The implementation and evaluation of a peer education and support programme in secondary schools to prevent and reduce high-risk sexual behaviour amongst adolescents is discussed.The aims of the programme were to provide accurate information about HIV/AIDS, discuss and reconsider peer group norms, and establish support for learners. In the programme that was implemented in 13 secondary schools in Tshwane, South Africa, peer educators were identified, trained and supported to implement the programme in their schools with the assistance of a teacher and postgraduate students as facilitators. Peer educators organised HIV awareness activities, facilitated class discussions on risk behaviour and gender relationships, and supported learners in solving personal problems. Process evaluation included weekly reports and focus group discussions with peer educators and teachers. A quasiexperimental design involving an experimental and control group, as well as pre- and post-assessments, was used to evaluate the impact of the programme on psychological well-being, personal control, school climate and reported high-risk behaviour of learners aged between 13 and 20 years.The results showed that the percentage of learners in the experimental group who were sexually experienced remained unchanged over the time period of 18 months. In contrast, a significantly increased percentage of learners in the control group were sexually experienced after the same time period.The control group also perceived more of their friends to be sexually experienced. No differences were reported in condom use in either of the groups.The findings of this study suggest that peer education can contribute to a delayed onset of sexual activity, and can therefore contribute to the prevention of HIV/AIDS amongst adolescents.
