RESUMO
BACKGROUND: Voluntary medical male circumcision (VMMC) reduces the risk of male HIV acquisition by 60%. Programmes to provide VMMCs for HIV prevention have been introduced in sub-Saharan African countries with high HIV burden. Traditional circumcision is also a long-standing male coming-of-age ritual, but practices vary considerably across populations. Accurate estimates of circumcision coverage by age, type, and time at subnational levels are required for planning and delivering VMMCs to meet targets and evaluating their impacts on HIV incidence. METHODS: We developed a Bayesian competing risks time-to-event model to produce region-age-time-type specific probabilities and coverage of male circumcision with probabilistic uncertainty. The model jointly synthesises data from household surveys and health system data on the number of VMMCs conducted. We demonstrated the model using data from five household surveys and VMMC programme data to produce estimates of circumcision coverage for 52 districts in South Africa between 2008 and 2019. RESULTS: Nationally, in 2008, 24.1% (95% CI: 23.4-24.8%) of men aged 15-49 were traditionally circumcised and 19.4% (18.9-20.0%) were medically circumcised. Between 2010 and 2019, 4.25 million VMMCs were conducted. Circumcision coverage among men aged 15-49 increased to 64.0% (63.2-64.9%) and medical circumcision coverage to 42% (41.3-43.0%). Circumcision coverage varied widely across districts, ranging from 13.4 to 86.3%. The average age of traditional circumcision ranged between 13 and 19 years, depending on local cultural practices. CONCLUSION: South Africa has made substantial, but heterogeneous, progress towards increasing medical circumcision coverage. Detailed subnational information on coverage and practices can guide programmes to identify unmet need to achieve national and international targets.
Voluntary medical male circumcision reduces the risk of male HIV acquisition. Programmes to provide circumcisions for HIV prevention have been introduced in sub-Saharan African countries with high HIV burden. Estimates of circumcision coverage are needed for planning and delivering circumcisions to meet targets and evaluate their impacts on HIV incidence. We developed a model to integrate date from both household surveys and health systems on the number of circumcisions conducted, and applied it to understand how the practices and coverage of circumcision are changing in South Africa. National circumcision coverage increased considerably between 2008 and 2019, however, there remains a substantial subnational variation across districts and age groups. Further progress is needed to reach national and international targets.
RESUMO
BACKGROUND: Young women in South Africa are at high risk for HIV, particularly after they leave school. There are few studies examining the long-term impact of school-based public health interventions aimed at protecting young women from HIV. We undertook a long-term evaluation of an extracurricular, school-based HIV prevention program, that leveraged off a mass media television series in South Africa. METHODS: We recruited 403 women aged 18-28 years. One hundred and seventy were members of Soul Buddyz Clubs (SBCs) between 2004 and 2008 and 233 were matched controls from the same communities as the ex-Buddyz. Face-to-face interviews were conducted and HIV testing undertaken. Analysis was restricted to 320 women who had ever had sex (136 ex-Buddyz and 184 controls). Multivariate analysis in Stata v14 was conducted. FINDINGS: 16.4% of women tested HIV positive. Ex-Buddyz were more likely to be HIV negative than controls (AOR 2.92, 95% CI 1.26-6.77, p = 0.013). Ex-Buddyz were more likely to have only had one sexual partner in the past year (AOR 2.14, 95% CI 1.17-3.89, p = 0.013) and 1.7 times more likely to have used a condom at first sex (95% CI 0.99-2.92, p = 0.053). INTERPRETATION: Participation in an SBC is associated with a decrease in young women's HIV risk and suggests an impact on some key risky sexual behaviors. School-based prevention programs that leverage off of other media platforms demonstrate a positive outcome on health status.
