After decades of research, South African women continue to have the highest burden of HIV in the world. The aim of the study is to investigate the impact of marital status on HIV using population and community-level data sources. We included data 13,469 and 5682 South African women who participated to South African HIV behavioural surveys in 2002–2012 and 2017, respectively. HIV prevalence and incidence rates were significantly higher among single/not-cohabiting women compared to those married/cohabiting with a partner in all survey participants (adjusted odds ratio (aOR): 1.60 and 1.58 in 2002–2012 and 2017, respectively). A quarter of the HIV diagnoses were attributed to those who were single/not-cohabiting women (population attributable risk (PAR%): 25% and 24%, respectively). More than 40% of the HIV infections were exclusively associated with single women (PAR%: 42%, 95% CI: 33%, 51%). Our results provided strong evidence for the profound impact of marital status on excess HIV infection rates. Targeting and reaching single/not-cohabiting women with multiple risk factors can potentially play a crucial role in the trajectories of the epidemic. [ABSTRACT FROM AUTHOR]

Supplemental Digital Content is Available in the Text. Background: Intimate partner violence (IPV) may affect the HIV-treatment cascade. Setting: Four high HIV-prevalence DREAMS health districts in South Africa. Methods: Secondary analysis of cross-sectional data collected March 2017–June 2018, using random household sample of young (12–24 years) girls and women. Face-to-face interviews assessed IPV and HIV-status knowledge, and finger-prick blood draws assessed ART (antiretroviral therapy) uptake and viral suppression. We used logistic regression to estimate crude and adjusted effects of IPV on HIV knowledge, ART uptake, and viral suppression. Results: Of 18,230 adolescent girls and young women, 8413 (46%) reported ever having had sex, of whom 1118 (13%) were HIV positive. The 90:90:90 benchmarks were 61% knew their status, 86% had ART present in their blood sample, and 91% were virally suppressed. Among the entire sample of young women living with HIV, 65.6% were virally suppressed. Past year IPV was reported by 15%. In adjusted models, IPV trended toward increasing the odds that a young woman was aware she was living with HIV [adjusted odds ratios (aOR) = 1.40, 2.00–9.98, P = 0.067]. There was no association between IPV and reduced treatment use (aOR = 0.73, 0.41–1.29). IPV was independently associated with reduced viral suppression (aOR = 0.30, 0.13–0.66). Conclusions: Addressing the role of IPV in undermining the treatment cascade for adolescent and young women is a critical issue for HIV programming. [ABSTRACT FROM AUTHOR]

South Africa has the highest number of HIV infected individuals in the world. The primary objective of the current study was to describe temporal changes in HIV incidence rates using the data from 9,948 women who enrolled in one of the six HIV prevention trials conducted in KwaZulu-Natal, South Africa. Characteristics of the study population were presented and compared across the four study periods: 2002–2004, 2005–2008, 2009–2011 and 2012–2016. HIV infection rates increased from 6.2 to 9.3 per 100 person-year over the 15 years. These rates were as high as 14 per 100 person-year among women younger than 20 years age. Being single/not cohabiting, using injectable contraceptives, having less than two children, and diagnosed with STI(s) were associated with increased risk of HIV infection. These four factors were associated with 71%, 75%, 80% and 88% of the HIV seroconversions in four study periods. As the research continues to find ways of controlling the spread of the infections, quantifying the temporal trends in risk factors and their population-level impacts on HIV infection may have significant implications. This information may assist in developing effective counselling and education programs by targeting the sexually active single women and delivering more realistic messages. [ABSTRACT FROM AUTHOR]

Inadequate toilet facilities may increase women's risk of experiencing non-partner sexual violence. We sought to assess the association between young (18–24 year-olds) women's access to toilets and past year non-partner rape experience, in deprived communities in South Africa. Data came from cross-sectional, population-based survey from poor communities from four health districts in two provinces, namely, City of Johannesburg, and Ekurhuleni in Gauteng, and eThekwini and uMgungundlovu, in KwaZulu-Natal. Descriptive, unadjusted and adjusted associations, were estimated in STATA/IC16, accounting for study design. In total, 10,635 young women provided data on toilet access. Past year non-partner rape prevalence was 5.7%. In adjusted analyses, those reporting a shared toilet were more likely to report past year experience of non-partner rape (adjusted odds ratio: 1.45, 95% confidence intervals [1.17, 1.80]), compared to those with their own toilet indoors. Improving access to private, secure toilets is an important component for the prevention of non-partner sexual violence. [ABSTRACT FROM AUTHOR]

In addition to being the epicentre of the HIV epidemic, South Africa also has the highest burden of sexually transmitted infections (STIs) in the world. Therefore, understanding the most influential risk factors of STIs is a research priority. Using the data from 9948 women who resided in KwaZulu Natal, South Africa, we estimated the population attributable risk to quantify the combined impacts of the most influential factors on STI diagnosis. Overall STI prevalence was 20%, and STI incidence was 15 per 100 person-years. Four factors: age at sexual debut, single/not cohabiting, two or more sex partners and parity <3 were identified as the most influential risk factors for STI prevalence and incidence rates. However, these factors collectively associated with only 51% and 53% of the excess STI prevalence and incidence rates, respectively. These relatively modest impacts provide empirical evidence for the significant impacts of unmeasured factors on STIs. Culturally and socially appropriate prevention programs may be more effective to target those at highest risk of STIs. [ABSTRACT FROM AUTHOR]

In South Africa, mass media and interpersonal communication sources have been used extensively to increase awareness of human immunodeficiency virus (HIV)/AIDS. A sub-population of 10,565 black Africans who participated in the 2011–2012 household survey was analysed. Overall compared to men, a higher proportion of women had ever been tested for HIV (76% versus 60%). In age-specific analysis, men and women aged 25–49 years were more likely to be ever been tested compared to the youngest (<25 years) and the oldest age groups (50+ years). More than 80% of the study population was exposed to mass media tools, while exposure to interpersonal information sources was less common (16–72%). Among adolescents, 37% (men) and 41% (women) of the HIV tests were collectively associated with exposure to interpersonal programmes, while mass media tools had substantial contributions on HIV testing rates among the older individuals. Information sources to promote HIV/AIDS awareness should be tailored to reduce age–gender disparities. [ABSTRACT FROM AUTHOR]

South Africa has the highest burden of human immunodeficiency virus (HIV) infections in the world with significant geographical variations. We identified the predictors of HIV infections and their sub-geographical-level contributions to the epidemic using a decade long data (2002-2012) from 6484 South African women. Generalized additive models were used to uncover the most significant features of these estimates across the region. In the overall analysis, younger age, not married or cohabiting with a partner, partner has another partner(s) and null/prim parity, using injectable contraceptives and presence of other sexually transmitted infections (STIs) were identified as independent predictors of HIV seroconversions. Overall, the top three highest contributors to infections were women's marital status (PAR% = 73%, 95% CI: 68%, 77%), parity (PAR% = 47%, 95% CI: 42%, 53%) and partnership factors (PAR% = 37%, 95% CI: 30%, 44%). However, their contributions varied remarkably at sub-geographical level. This was mainly due to the substantial localized variations in their prevalence and hazard ratios across the region. Our results will guide policy makers to develop tailored prevention strategies in order to allocate scarce resources by targeting the most significant contributors of HIV infection at sub-geographical level.
