RESUMO
Transactional sex increases sub-Saharan African women's risk of HIV acquisition. We quantitatively explored the pathways contributing towards women's future engagement in transactional sex with casual partners and khwapheni (secret concurrent sex partners). We conducted secondary data analysis from a cluster randomised controlled trial in urban informal settlements in eThekwini Municipality., South Africa. Data were collected at enrolment (t0) and 24 months' later (t2) using self-completed questionnaires. Structural equation modelling (SEM) assessed pathways leading to transactional sex over two years. 677 women 18-35 years were enrolled and 80.5% (n = 545) were followed up. At t2, 44.6% of respondents reported transactional sex with a casual partner or khwapheni. The SEM demonstrated a small effect (d = 0.23) between transactional sex at t0 and at t2. Controlling for past transactional sex, main partner relationship control had a large effect size on future transactional sex (d = 0.60). Hazardous drinking had a medium effect size (d = 0.45) and food insecurity a small effect (d = 0.24), (RMSEA 0.03, 90%CI 0.02-0.04; CFI 0.97; TLI 0.96). HIV prevention programming should highlight current transactional sex but also address structural issues predicting future transactional sex, including food insecurity and alcohol misuse. Gender transformative interventions to reduce controlling behaviours in main relationships are worth investigating.

BACKGROUND: Seroprevalence studies are important for quantifying the burden of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infections in resource-constrained countries. METHODS: We conducted a cross-sectional household survey spanning the second pandemic wave (November 2020 to April 2021) in 3 communities. Blood was collected for SARS-CoV-2 antibody (2 enzyme-linked immunosorbent assays targeting spike and nucleocapsid) and human immunodeficiency virus (HIV) testing. An individual was considered seropositive if testing positive on ≥1 assay. Factors associated with infection, and the age-standardized infection case detection rate, infection hospitalization rate, and infection fatality rate were calculated. RESULTS: Overall, 7959 participants were enrolled, with a median age of 34 years and an HIV prevalence of 22.7%. SARS-CoV-2 seroprevalence was 45.2% (95% confidence interval 43.7%-46.7%) and increased from 26.9% among individuals enrolled in December 2020 to 47.1% among those enrolled in April 2021. On multivariable analysis, seropositivity was associated with age, sex, race, being overweight/obese, having respiratory symptoms, and low socioeconomic status. Persons living with HIV with high viral load were less likely to be seropositive than HIV-uninfected individuals. The site-specific infection case detection rate, infection hospitalization rate, and infection fatality rate ranged across sites from 4.4% to 8.2%, 1.2% to 2.5%, and 0.3% to 0.6%, respectively. CONCLUSIONS: South Africa has experienced a large burden of SARS-CoV-2 infections, with <10% of infections diagnosed. Lower seroprevalence among persons living with HIV who are not virally suppressed, likely as a result of inadequate antibody production, highlights the need to prioritize this group for intervention.

Few studies have explored the relationship between transactional sex and HIV in adult men, with even fewer exploring the predictors of providing money or goods in exchange for sex. This study aimed to characterise the predictors and patterns of transactional sex in adult men in an urban informal area in South Africa. We used baseline, cross-sectional data from a study of 2406 men aged 18-40 years from an urban informal area. Past year transactional sex was assessed through questions adapted from those used previously. Controlling behaviour was measured using an adapted Sexual Relationship Power Scale. Multivariable logistic regression was used to determine associations between transactional sex and other potential explanatory variables. Nearly half (47%) of respondents who had ever had sex reported at least one type of transactional sex with a casual partner in the past year. A third of men provided support or money for a sex partner's family, 30% provided cash and 28% provided somewhere to stay. Controlling for other factors, men with higher levels of controlling behaviour had nearly double the odds of engaging in transactional sex. Men reporting three or more sexual partners had significantly higher odds of engaging in transactional sex. Hazardous drinkers had 33% higher odds of engaging in transactional sex. Men's provision of money or goods in exchange for sex with women is related to other high-risk behaviours, such as multiple sexual partners, hazardous drinking and controlling behaviour. To address transactional sex-related HIV risks, programming should address harmful masculinities, including relationship control.

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.

BACKGROUND: Oral HIV pre-exposure prophylaxis (PrEP) is highly effective, but alternative delivery options are needed to reach more users. Microarray patches (MAPs), a novel drug-delivery system containing micron-scale projections or "microneedles" that deliver drugs via skin, are being developed to deliver long-acting HIV PrEP and as a multipurpose prevention technology to protect from HIV and unintended pregnancy. We explored whether MAP technology could meet user and health system needs in two African countries. METHODS: Researchers in South Africa and Uganda conducted 27 focus group discussions, 76 mock-use exercises, and 31 key informant interviews to explore perceptions about MAPs and specific features such as MAP size, duration of protection, delivery indicator, and health system fit. Participants included young women and men from key populations and vulnerable groups at high risk of HIV and/or unintended pregnancy, including adolescent girls and young women; female sex workers and men who have sex with these women; and men who have sex with men. In Uganda, researchers also recruited young women and men from universities and the community as vulnerable groups. Key stakeholders included health care providers, sexual and reproductive health experts, policymakers, and youth activists. Qualitative data were transcribed, translated, coded, and analyzed to explore perspectives and preferences about MAPs. Survey responses after mock-use in Uganda were tabulated to assess satisfaction with MAP features and highlight areas for additional refinement. RESULTS: All groups expressed interest in MAP technology, reporting perceived advantages over other methods. Most participants preferred the smallest MAP size for ease of use and discreetness. Some would accept a larger MAP if it provided longer protection. Most preferred a protection duration of 1 to 3 months or longer; others preferred 1-week protection. Upper arm and thigh were the most preferred application sites. Up to 30 minutes of wear time was considered acceptable; some wanted longer to ensure the drug was fully delivered. Self-administration was valued by all groups; most preferred initial training by a provider. CONCLUSIONS: Potential users and stakeholders showed strong interest in/acceptance of MAP technology, and their feedback identified key improvements for MAP design. If a MAP containing a high-potency antiretroviral or a MAP containing both an antiretroviral and hormonal contraceptive is developed, these products could improve acceptability/uptake of protection options in sub-Saharan Africa.

Introduction: South Africa has the largest number of confirmed cases of COVID-19 in Africa. Data to inform public health strategies to mitigate the spread of new variants and severity of disease is needed, including information on knowledge, attitudes and practices (KAP) regarding COVID-19, factors associated with intention to get vaccinated, and viewpoints on reliable sources of data. Methods: we investigated these topics as part of the COVID-19 healthcare utilization and seroprevalence (HUTS) cross-sectional survey in three communities in South Africa: Mitchell´s Plain (Western Cape Province), Pietermaritzburg (KwaZulu-Natal Province) and Klerksdorp (North West Province) during and after the second wave of COVID-19 prior to vaccine availability. Results: primary caregivers from 5799 households participated in the study, 41.1% from Pietermaritzburg, 34.2% from Klerksdorp and 24.7% from Mitchells Plain. Two-thirds and 94.7% of respondents had correct knowledge on the cause and spread of COVID-19, respectively. Knowledge measures were significantly associated with age less than 65 years, the highest level of education and site (Mitchells Plain). Desired preventive behaviors were associated with higher socio-economic status. While 64.7% of people intended to get vaccinated, those over 64 years of age were more likely to intend to vaccinate (aOR: 1.25, 95% CI: 1.06-1.47). Vaccine intention related to protection of self (58.4%) and family (40.0%). The most trusted source of COVID-19 information was television (59.3%) followed by radio (20.0%). Conclusion: these data can be used to design targeted public health campaigns for the current COVID-19 and future epidemics, ensuring that socio-economic constraints and preference for trusted information are considered.

Healthcare utilization surveys contextualize facility-based surveillance data for burden estimates. We describe healthcare utilization in the catchment areas for sentinel site healthcare facilities during the first year of the COVID-19 pandemic. We conducted a cross-sectional healthcare utilization survey in households in three communities from three provinces (KwaZulu-Natal, Western Cape and North West). Field workers administered structured questionnaires electronically with the household members reporting influenza-like illness (ILI) in the past 30 days or severe respiratory illness (SRI) since March 2020. Multivariable logistic regression was used to identify factors associated with healthcare utilization among individuals that reported illness. From November 2020 through April 2021, we enrolled 5804 households and 23,003 individuals. Any respiratory illness was reported by 1.6% of individuals; 0.7% reported ILI only, 0.8% reported SRI only, and 0.1% reported both ILI and SRI. Any form of medical care was sought by 40.8% (95% CI 32.9% - 49.6%) and 71.3% (95% CI 63.2% - 78.6%) of individuals with ILI and SRI, respectively. On multivariable analysis, respiratory illness was more likely to be medically attended for individuals at the Pietermaritzburg site (aOR 3.2, 95% CI 1.1-9.5, compared to Klerksdorp), that were underweight (aOR 11.5, 95% CI 1.5-90.2, compared to normal weight), with underlying illness (aOR 3.2, 95%CI 1.2-8.5), that experienced severe illness (aOR 4.8, 95% CI 1.6-14.3) and those with symptom duration of ≥10 days (aOR 7.9, 95% CI 2.1-30.2, compared to <5 days). Less than half of ILI episodes and only 71% of SRI episodes were medically attended during the first two COVID-19 waves in South Africa. Facility-based data may underestimate disease burden during the COVID-19 pandemic.

BACKGROUND: Qualitative research emphasizes men's experiences of trauma increase HIV risk. We seek to understand associations between experience of traumatic events and HIV-risk behaviors among heterosexual men in 2 trials in urban informal settlements in South Africa. METHODS: Cross-sectional surveys among men in Johannesburg and Durban, South Africa, enrolled in intervention trials. Adjusted logistic regression and structural equation modeling assessed associations between men's experiences of poverty and traumatic events, and HIV-risk behaviors (inconsistent condom use, transactional sex, and number of sex partners). We explored mediated pathways from trauma to HIV risk through mental health and alcohol, and gender attitudes. RESULTS: Among 2394 men, in adjusted logistic regression, transactional sex and 4 or more sex partners were associated with witnessing the murder of a family member, witnessing a murder of a stranger, experiencing excessive pain, been kidnapped, and witnessing a rape. More consistent condom use was associated with witnessing the murder of a family member, being kidnapped, and witnessing a rape. In 3 separate structural equation modeling pathways were consistent, trauma directly increased transactional sex, and past year sexual partners, and increased consistent condom use. Risk was increased through mental health pathways, and gender inequitable attitudes and practices. CONCLUSION: Men's HIV-risk behaviors in this population emerge at the confluence of poverty, traumatic experiences, and gender inequalities. Effective HIV-prevention interventions needs to reduce men's experiences of poverty and trauma, transform gender norms, and reduce the mental health impact of trauma.

BACKGROUND: Transactional sex is a risk factor for HIV infection. Alcohol use may increase the risk of transactional sex. No nationally-representative studies have examined the relationship between multiple dimensions of alcohol use and transactional sex in women in South Africa. The aim of the study was to examine the relationship between alcohol dependence, binge drinking and frequency of drinking in the past month and transactional sex in adult women in South Africa. METHODS: A cross-sectional study using multi-stage, cluster sampling collected data from a nationally representative sample of 5,969 women aged 16-55 years in 2012. The analysis conducted for this paper was restricted to women reporting sexual activity in the past 12 months (n = 3,594). Transactional sex was defined as having received money/gifts in exchange for sex with any sex partner in the past year. Alcohol use measures included: alcohol dependence (≥2 positive responses to the CAGE questionnaire); binge drinking (≥4 drinks for women on one occasion); and drinking frequency in the previous month. Logistic regression models were built to test the hypotheses that each dimension of alcohol use was associated with transactional sex. RESULTS: About 6.3% (n = 225) of sexually active women reported transactional sex. Almost a third (30.6%) of sexually active women had ever drunk alcohol, and 19.2% were current (past month) drinkers. Among lifetime drinkers, 28.0% were alcohol dependent and 56.6% were binge drinkers. Alcohol dependent women were twice as likely to report transactional sex (AOR 2.0, 95% CI 1.1-4.3, p<0.05) than those not alcohol dependent. Binge drinkers were 3.1 times more likely to have had transactional sex (95% CI 1.5-6.6, p<0.01) than non-binge drinkers. There was no significant relationship between frequency of drinking in the past month and transactional sex. CONCLUSION: Alcohol dependency and binge drinking are significantly associated with transactional sex in South African women. HIV prevention programmes need to target these women, and address both their alcohol use, as well as the HIV risks associated with transactional sex.
