RESUMO

BACKGROUND: Notions of ideal manhood in South Africa are potentially prescriptive of male sexuality thus accounting for the behaviors which may lead to men being at greater HIV risk. We tested the hypothesis that gender and relationship constructs are associated with condom use among young men living in rural South Africa. METHODS: 1219 men aged 15-26 years completed a cross-sectional baseline survey from an IsiXhosa questionnaire asking about sexual behaviour and relationships. Univariate and bivariate analyses described condom use patterns and explanatory variables, and multinomial regression modeling assessed the factors associated with inconsistent versus consistent and non-condom use. RESULTS: 47.7% of men never used condoms, when 36.9% were inconsistent and 15.4% were consistent with any partner in the past year. Condom use patterns differed in association with gender relations attitudes: never users were significantly more conservative than inconsistent or consistent users. Three gender positions emerged indicating that inconsistent users were most physically/sexually violent and sexually risky; never users had more conservative gender attitudes but were less violent and sexually risky; and consistent users were less conservative, less violent and sexually risky with notably fewer sexual partners than inconsistent users. CONCLUSIONS: The confluence of conservative gender attitudes, perpetration of violence against women and sexual risk taking distinguished inconsistent condom users as the most risky compared to never condom users, and rendered inconsistent use one of the basic negative attributes of dominant masculinities in the Eastern Cape, South Africa. This finding is important for the design of HIV prevention and gender equity interventions and emphasizes the need for a wider roll-out of interventions that promote progressive and healthy masculine practices in the country.

RESUMO

BACKGROUND: This paper aims to describe factors associated with HIV sero-status in young, rural South African women and the relationship between intimate partner violence (IPV) and HIV. METHODS: A total of 1295 sexually active female volunteers, aged 15-26, from 70 villages were recruited to participate in a cluster randomized controlled trial of an HIV behavioural intervention. The main measures were HIV sero-status, and IPV and sexual practices measured using a questionnaire administered during baseline interviews. RESULTS: About 12.4% of women had HIV and 26.6% had experienced more than one episode of physical or sexual IPV. After adjusting for age, HIV infection was associated with having three or more past year partners [odds ratio (OR) 2.39; 95% confidence interval (95% CI) 1.48-3.85], sex in past 3 months (OR 3.33; 95% CI 1.87-5.94), a partner three or more years older (OR 1.69; 95% CI 1.16-2.48), and a more educated partner (OR 1.91; 95% CI 1.30-2.78). IPV was associated with HIV in two-way analyses (OR 1.56; 95% CI 1.08-2.23), but the effect was non-significant after adjusting for HIV risk behaviours. The experience of IPV was strongly associated with past year partner numbers, time of last sex, and partner's education; it was also marginally associated with partner age difference. Adverse experiences in childhood, including sexual abuse, increased the likelihood of having more past year partners (OR 1.43; 95% CI 1.21-1.69). CONCLUSIONS: IPV was strongly associated with most of the identified HIV risk factors. Our findings provide further evidence of links between IPV and HIV among women and the importance of joint prevention.

RESUMO

OBJECTIVE: To describe factors associated with HIV infection in men aged 15-26 years. SETTING: Rural Eastern Cape Province, South Africa. SAMPLE: A total of 1277 sexually experienced Xhosa male volunteers from 70 villages participating in a cluster randomized controlled trial of an HIV behavioural intervention. Xhosas circumcise during manhood initiation rituals. DESIGN: Cross-sectional, analysis of the study's baseline interviews. MAIN MEASURE: HIV sero-status, sexual practices measured with an interviewer-administered questionnaire. RESULTS: About 2% of the men were HIV positive. A logistic regression model showed HIV positivity to be associated with age (OR 1.55; 95%CI 1.22-1.95), having made a woman pregnant (OR 2.93; 95% CI 1.28-6.68), having been circumcised (OR 0.40; 95% CI 0.16-0.98), and having had sex with a man (OR 3.61; 95% CI 1.0-13.0). CONCLUSIONS: Our findings provide further evidence to suggest that circumcision is protective. There was much heterosexual risk taking among men but only pregnancy (with its association with sexual frequency) predicted HIV sero-positivity. Although relatively rare, same-sex sexual experiences were a risk factor. Male-male sexual contact is rarely assessed in HIV research in Africa and almost never addressed in general HIV prevention programming. Our findings suggest that it should be given more attention.

RESUMO

BACKGROUND: Viral load (VL) quantification is an important tool in determining newly developed drug resistance or problems with adherence to antiretroviral therapy (ART) in HIV-positive patients. VL monitoring is becoming the standard of care in many resource-limited settings. Testing in resource-limited settings may require sampling by fingerstick because of general shortages of skilled phlebotomists and the expense of venepuncture supplies and problems with their distribution. OBJECTIVE: To assess the feasibility and ease of collecting 150 µL capillary blood needed for the use of a novel collection device following a classic fingerstick puncture. METHODS: Patients were recruited by the study nurse upon arrival for routine ART monitoring at the Themba Lethu Clinic in Johannesburg, South Africa. Each step of the fingerstick and blood collection protocol was observed, and their completion or omission was recorded. RESULTS: One hundred and three patients consented to the study, of whom three were excluded owing to the presence of callouses. From a total of 100 patients who consented and were enrolled, 98% of collection attempts were successful and 86% of participants required only one fingerstick to successfully collect 150 µL capillary blood. Study nurse adherence to the fingerstick protocol revealed omissions in several steps that may lower the success rate of capillary blood collection and reduce the performance of a subsequent VL assay. CONCLUSION: The findings of this study support the feasibility of collecting 150 µL of capillary blood via fingerstick for point-of-care HIV-1 VL testing in a resource-limited setting.

RESUMO

OBJECTIVE: To assess the impact of Stepping Stones, a HIV prevention programme, on incidence of HIV and herpes simplex type 2 (HSV-2) and sexual behaviour. DESIGN: Cluster randomised controlled trial. SETTING: 70 villages (clusters) in the Eastern Cape province of South Africa. PARTICIPANTS: 1360 men and 1416 women aged 15-26 years, who were mostly attending schools. INTERVENTION: Stepping Stones, a 50 hour programme, aims to improve sexual health by using participatory learning approaches to build knowledge, risk awareness, and communication skills and to stimulate critical reflection. Villages were randomised to receive either this or a three hour intervention on HIV and safer sex. Interviewers administered questionnaires at baseline and 12 and 24 months and blood was tested for HIV and HSV-2. PRIMARY OUTCOME MEASURE: incidence of HIV. Other outcomes: incidence of HSV-2, unwanted pregnancy, reported sexual practices, depression, and substance misuse. RESULTS: There was no evidence that Stepping Stones lowered the incidence of HIV (adjusted incidence rate ratio 0.95, 95% confidence interval 0.67 to 1.35). The programme was associated with a reduction of about 33% in the incidence of HSV-2 (0.67, 0.46 to 0.97; P=0.036)-that is, Stepping Stones reduced the number of new HSV-2 infections over a two year period by 34.9 (1.6 to 68.2) per 1000 people exposed. Stepping Stones significantly improved a number of reported risk behaviours in men, with a lower proportion of men reporting perpetration of intimate partner violence across two years of follow-up and less transactional sex and problem drinking at 12 months. In women desired behaviour changes were not reported and those in the Stepping Stones programme reported more transactional sex at 12 months. CONCLUSION: Stepping Stones did not reduce incidence of HIV but had an impact on several risk factors for HIV-notably, HSV-2 and perpetration of intimate partner violence. TRIAL REGISTRATION: Clinical Trials NCT00332878.

RESUMO

OBJECTIVE: To describe the study design, methods and baseline findings of a behavioural intervention trial aimed at reducing HIV incidence. METHOD: A cluster randomized-controlled trial (RCT) conducted in 70 villages in rural South Africa. A behavioural intervention, Stepping Stones, was implemented in 35 communities in two workshops of 20 men and 20 women in each community who met for 17 sessions (50 h) over a period of 3-12 weeks. Individuals in the control arm communities attended a single session of about 3 h on HIV and safer sex. Impact assessment was conducted through two questionnaire and serological surveys at 12-month intervals. The primary outcome was HIV incidence and secondary measures included changes in knowledge, attitude and sexual behaviours. Qualitative research was also undertaken with 10 men and 10 women from two sites receiving the intervention (one rural and one urban) and five men and five women from one village in the control arm. They were interviewed individually three times prior to the workshops and then 9-12 months later. RESULTS: A total of 2776 participants (1409 intervention and 1367 control) were enrolled at baseline and had an interview, and HIV sero-status was established. HIV baseline prevalence rates in women were 9.8% in the intervention arm and 12.8% in the control arm. In men the prevalence was 1.7% in the intervention arm and 2.1% in the control arm. Demographic and behavioural characteristics were similar in the two arms. In the intervention groups 59.9% of participants attended more than 75% of the sessions. In the control group 66.3% attended the control session. CONCLUSION: This is the third RCT to be conducted in sub-Saharan Africa evaluating a behavioural intervention using HIV incidence as a primary outcome. It is of particular interest as the intervention in question is used in many developing countries. There is good baseline comparability between the study arms and the process data on the workshops suggested that the interventions were feasible and adequately implemented.
