Objective: This study investigated whether young women's participation in a combination HIV-prevention intervention was associated with accessing and using condoms and other contraceptives.Study Design: A cross-sectional household survey was conducted from 2017 to 2018 among a representative sample of young women aged 15-24 years old living in six South African districts in which the intervention was implemented. Cross-tabulations and multivariate regression analyses of weighted data were performed to examine access to and use of condoms and other contraceptives.Results: In total 4399 young women participated, representing a 60.6% response rate. Of participants, 61.0% (n = 2685) reported accessing condoms and other contraceptives in the past year. Among those who ever had sex (n = 3009), 51.0% used condoms and 37.4% other contraceptives at last sex. Among 15-19 year old, participation in the combination intervention was positively associated with reporting contraceptive use other than condoms at last sex (Prevalence Ratio (PR): 1.36; 95% CI: 1.21-1.53) and reporting use of both condoms and other contraceptives at last sex (PR: 1.45; 95% CI: 1.26-1.68). No associations were observed in the age group 20-24.Conclusion: Our findings suggest that combination HIV prevention interventions may lead to increased access and use of condoms and other methods of contraception among adolescent women, but this needs to be confirmed in experimental studies. We need to test different or more intensive interventions to increase contraceptive use in young women aged 20-24.Implications: Participating in combination HIV prevention interventions that are delivered via multiple approaches may promote access to, and use of condoms and other methods of contraceptives among adolescent women, and thereby help reduce unintended pregnancies.

Objectives: South Africa has made remarkable progress in increasing the coverage of antiretroviral therapy (ART) among pregnant women; however, viral suppression among pregnant women receiving ART is reported to be low. Access to routine viral load testing is crucial to identify women with unsuppressed viral load early in pregnancy and to provide timely intervention to improve viral suppression. This study aimed to determine the coverage of maternal viral load monitoring nationally, focusing on viral load testing, documentation of viral load test results, and viral suppression (viral load < 50 copies/mL). At the time of this study, the first‐line regimen for women initiating ART during pregnancy was non‐nucleoside reverse transcriptase (NNRTI)‐based regimen. Methods: Between 1 October and 15 November 2019, a cross‐sectional survey was conducted among 15‐ to 49‐year‐old pregnant women attending antenatal care in 1589 nationally representative public health facilities. Data on ART status, viral load testing and viral load test results were extracted from medical records. Logistic regression was used to examine factors associated with coverage of viral load testing. Results: Of 8112 participants eligible for viral load testing, 81.7% received viral load testing, and 94.1% of the viral load test results were documented in the medical records. Of those who had viral load test results documented, 74.1% were virally suppressed. Women initiated on ART during pregnancy and who received ART for three months had lower coverage of viral load testing (73%) and viral suppression (56.8%) compared with women initiated on ART before pregnancy (82.8% and 76.1%, respectively). Initiating ART during pregnancy rather than before pregnancy was associated with a lower likelihood of receiving a viral load test during pregnancy (adjusted odds ratio = 1.6, 95% confidence interval: 1.4–1.8). Conclusions: Viral load result documentation was high; viral load testing could be improved especially among women initiating ART during pregnancy. The low viral suppression among women who initiated ART during pregnancy despite receiving ART for three months highlights the importance of enhanced adherence counselling during pregnancy. Our finding supports the WHO recommendation that a Dolutegravir‐containing regimen be the preferred regimen for women who are newly initiating ART during pregnancy for more rapid viral suppression.

Southern Africa remains the epicentre of the human immunodeficiency virus (HIV) epidemic with AIDS the leading cause of death amongst adolescents. Poor policy translation, inadequate programme implementation and fragmentation of services contribute to adolescents' poor access to sexual and reproductive health and rights (SRHR) services. This study assessed an integrated, school-based SRHR and HIV programme, modelled on the South African Integrated School Health Policy in a rural, high HIV-prevalence district. A retrospective cohort study of 1260 high-school learners was undertaken to assess programme uptake, change in HIV knowledge and behaviour and the determinants of barrier-methods use at last sexual intercourse. Programme uptake increased (2%–89%; P < 0.001) over a 16-month period, teenage-pregnancy rates declined (14%–3%; P < 0.050) and accurate knowledge about HIV transmission through infected blood improved (78.3%–93.8%; P < 0.050), a year later. Post-intervention, attending a clinic perceived as adolescent-friendly increased the odds of barrier-methods use during the last sexual encounter (aOR=1.85; 95% CI: 1.31–2.60), whilst being female (aOR=0.69; 95% CI: 0.48–0.99), <15 years (aOR=0.44; 95% CI: 0.24–0.80), or having >5 sexual partners in the last year (aOR=0.59; 95% CI: 0.38–0.91) reduced the odds. This study shows that the unmet SRHR needs of under-served adolescents can be addressed through integrated, school-based SRHR programmes. [ABSTRACT FROM AUTHOR]

South Africa has the largest HIV burden and treatment program in the world. Diversion of HIV prevention and treatment medication for recreational use—or nonmedical use for psychoactive effects—is a public health concern globally and in South Africa. Few South African studies examine recreational use of HIV antiretrovirals (ARVs). The objective of this article is to evaluate the prevalence of recreational ARV use and to identify risk and protective factors associated with use. Data are drawn from a cross-sectional household survey of N = 4399 adolescent girls and young women (AGYW) aged 15–24 years in six districts across South Africa where an evaluation of a South African combination HIV prevention for girls and young women was implemented. The use of ARVs to "get high" was reported by 8.3% of AGYW across all districts. Logistic regressions showed that those engaging in transactional sex were at two times higher odds of recreational ARV use [adjusted odds ratio (aOR) = 2.01; confidence interval (95% CI): 1.51–2.68]. Recreational ARV use was more likely among those who used pre-exposure prophylaxis (PrEP) (aOR = 2.17; 95% CI: 1.36–3.48); HIV-positive participants who were not on ARVs for treatment (aOR = 0.36; 95% CI: 0.18–0.68); and those who were not virally suppressed (aOR, no vs. yes = 2.84; 95% CI: 1.21–6.66). As ARVs become more widely available for prevention and treatment, it will be important to monitor and address the possible emergence of ARVs as a substance for misuse or abuse.

Background: Continuity of care is important for child well-being in all settings where postnatal retention of mother-infant pairs in care remains a challenge. This analysis reports on completeness of patient-held infant Road to Health Booklets (RtHBs), amongst HIV exposed and unexposed infants during the first two years after the RtHB was launched country-wide in South Africa.Methods: Secondary data were analysed from two nationally representative, cross-sectional surveys, conducted in 2011-12 and 2012-13. These surveys aimed to measure early effectiveness of the national programme for preventing vertical HIV transmission. Participants were eligible for this analysis if they were 4-8 weeks old, receiving their six-week immunisation, not needing emergency care and had their RtHBs reviewed. Caregivers were interviewed and data abstracted from RtHBs. RtHB completeness across both surveys was defined as the proportion of RtHBs with any of the following indicators recorded: infant birth weight, BCG immunisation, maternal syphilis results and maternal HIV status. A partial proportional odds logistic regression model was used to identify factors associated with completeness. Survey sampling weights were included in all analyses.Results: Data from 10 415 (99.6%) participants in 2011-12 and 9529 (99.2%) in 2012-13 were analysed. Overall, recording of all four indicators increased from 23.1% (95% confidence interval (CI) = 22.2-24.0) in 2011-12 to 43.3% (95% CI = 42.3-44.4) in 2012-13. In multivariable models, expected RtHB completeness (ie, recording all four indicators vs recording of <4 indicators), was significantly (P<0.05) associated with survey year, marital status, socio-economic status, maternal antenatal TB screening, antenatal infant feeding counselling, delivery at a clinic or hospital and type of birth attendant.Conclusions: Routine patient-held infant health RtHB, a critical tool for continuity of care in high HIV/TB prevalence settings, was poorly completed, with less than 50% of the RtHB showing expected completeness. However, government efforts for improved usage of the booklet were evidenced by the near doubling of completeness from 2011 to 2013. Education about its importance and interventions aiming at optimising its use without violating user privacy should be continued. [ABSTRACT FROM AUTHOR]- Published

- Abstract
As oral tenofovir-based regimens for preexposure prophylaxis (PrEP) are adopted as standard of care for HIV prevention, their utilization in clinical trials among women in southern Africa will require an accurate estimate of oral PrEP efficacy in this population. This information is critical for women in choosing this prevention strategy, and in public health policy making. Estimates of the efficacy of oral PrEP regimens containing tenofovir have varied widely across trials that enrolled women, with some studies reporting high efficacy and others reporting no efficacy. Although poor adherence is strongly associated with lack of efficacy, other factors, such as mode of transmission (sexual vs. parenteral), predominant HIV subtype (C vs. non-C), intensity of exposure, and percentage of stable serodiscordant couples, may also contribute to the variation in efficacy estimates. In this article, we evaluate the evidence for PrEP efficacy in women and propose potential explanations for the observed differences in efficacy among studies. Our review emphasizes the need to continue to refine estimates of efficacy and effectiveness of tenofovir-based oral PrEP so as to best develop the next generation of HIV prevention tools, and to inform public policies directed toward HIV prevention.

Background: Achieving World Health Organization (WHO) recommendations for postnatal care (PNC) within the first few weeks of life is vital to eliminating early mother-to-child transmission of HIV (MTCT) and improving infant health. Almost half of the annual global deaths among children under five occur during the first six weeks of life. This study aims to identify uptake of three PNC visits within the first six weeks of life as recommended by WHO among South African mother-infant pairs, and factors associated with uptake.Methods: We analyzed data from three facility-based, nationally representative surveys (2010, 2011/12 and 2012/13) primarily designed to determine the effectiveness of the South African program to prevent MTCT. This analysis describes the proportion of infants achieving the WHO recommendation of at least 3 PNC visits. Interviews from 27 699 HIV-negative and HIV-positive mothers of infants aged 4-8 weeks receiving their six week immunization were included in analysis. Data were analyzed using STATA 13.0 and weighted for sample ascertainment and South African live births. We fitted a multivariable logistic regression model to estimate factors associated with early PNC uptake.Results: Over half (59.6%, 95% confidence interval (CI) = 59.0-60.3) of mother-infant pairs received the recommended three PNC visits during the first 6 weeks; uptake was 63.1% (95% CI = 61.9-64.3) amongst HIV exposed infants and 58.1% (95% CI = 57.3-58.9) amongst HIV unexposed infants. Uptake of early PNC improved significantly with each survey, but varied significantly by province. Multivariable analysis of the pooled data, controlling for survey year, demonstrated that number of antenatal visits (4+ vs <4 Adjusted odds ratio (aOR) = 1.13, 95% CI = 1.04-1.23), timing of initial antenatal visits (≤12 weeks vs >12 weeks, aOR = 1.13, 95% CI = 1.04-1.23), place of delivery (clinic vs hospital aOR = 1.5, 1.3-1.6), and infant HIV exposure (exposed vs unexposed aOR = 1.2, 95% CI = 1.1-1.2) were the key factors associated with receiving recommended PNC visits.Conclusions: Approximately 40% of neonates did not receive three or more postnatal care visits in the first 6 weeks of life from 2010-2013. To improve uptake of early PNC, early antenatal booking, more frequent antenatal care attendance, and attention to HIV negative women is needed. [ABSTRACT FROM AUTHOR]- Published

South Africa has one of the highest rates of both rape and HIV infections. Of great concern is the possibility of HIV transmission during the assault, but adherence to post-exposure prophylaxis (PEP) has been varied and low. We developed a telephonic psycho-social support, leaflet and adherence diary intervention for rape victims and tested its impact on adherence to PEP. A randomised control trial was conducted in the Western and Eastern Cape and 279 rape survivors were enrolled in two arms. The intervention involved the providing of an information leaflet including an adherence diary and follow-up support through telephone calls by a counsellor during the 28 days of taking the PEP. The controls received the leaflet. Follow-up interviews and tablet checks were done with 253 participants to assess adherence. The primary outcome was completion of 28 days of PEP with no more than three missed doses (94% adherence). There was more adherence in the intervention arm (38.2% vs. 31.9%), but the estimated intervention effect of 6.5% (95% CI: -4.6 to 17.6%) was not statistically significant, p=0.13. The intervention was associated with the reading of the pamphlet (p=0.07) and an increased use of the diary (p=0.01), but did not reduce depressive psychopathology. Overall adherence was greater amongst those who read the leaflet and used the medication diary. The study showed that the intervention was not effective in significantly improving adherence and adherence levels were low in both study arms. Further research to understand reasons for non-adherence is needed before further interventions are developed. [ABSTRACT FROM AUTHOR]

- Abstract
Supplemental Digital Content is Available in the Text. Background: During pregnancy and postpartum period, the sexual behaviors of women and their partners change in ways that may either increase or reduce HIV risks. Pregnant women are a priority population for reducing both horizontal and vertical HIV transmission. Setting: Nine sites in 4 South African provinces. Methods: Women aged 18–30 years were randomized to receive pericoital tenofovir 1% gel or placebo gel and required to use reliable modern contraception. We compared HIV incidence in women before, during, and after pregnancy and used multivariate Cox Proportional hazards models to compare HIV incidence by pregnancy status. Results: Rates of pregnancy were 7.1 per 100 woman-years (95% confidence interval [CI]: 6.3 to 8.1) and highest in those who reported oral contraceptive use (25.1 per 100 woman-years; adjusted hazard ratio 22.97 higher than other women; 95% CI: 5.0 to 105.4) or had 2 children. Birth outcomes were similar between trial arms, with 59.8% having full-term live births. No difference was detected in incident HIV during pregnancy compared with nonpregnant women (2.1 versus 4.3%; hazard ratio = 0.56, 95% CI: 0.14 to 2.26). Sexual activity was low in pregnancy and the early postpartum period, as was consistent condom use. Conclusions: Pregnancy incidence was high despite trial participation being contingent on contraceptive use. We found no evidence that rates of HIV acquisition were elevated in pregnancy when compared with those in nonpregnant women. Risks from reductions in condom use may be offset by reduced sexual activity. Nevertheless, high HIV incidence in both pregnant and nonpregnant women supports consideration of introducing antiretroviral-containing pre-exposure prophylaxis for pregnant and nonpregnant women in high HIV prevalence settings.
