RESUMEN
BACKGROUND: Antiretroviral therapy (ART) through universal test and treat (UTT) and HIV pre-exposure prophylaxis (PrEP) substantially reduces HIV-related mortality and incidence. Effective ART based prevention has not translated into population-level impact in southern Africa due to sub-optimal coverage among youth. We aim to investigate the effectiveness, implementation and cost effectiveness of peer-led social mobilisation into decentralised integrated HIV and sexual reproductive health (SRH) services amongst adolescents and young adults in KwaZulu-Natal (KZN). METHODS: We are conducting a type 1a hybrid effectiveness/implementation study, with a cluster randomized stepped-wedge trial (SWT) to assess effectiveness and a realist process evaluation to assess implementation outcomes. The SWT will be conducted in 40 clusters in rural KZN over 45 months. Clusters will be randomly allocated to receive the intervention in period 1 (early) or period 2 (delayed). 1) Intervention arm: Resident peer navigators in each cluster will approach young men and women aged 15-30 years living in their cluster to conduct health, social and educational needs assessment and tailor psychosocial support and health promotion, peer mentorship, and facilitate referrals into nurse led mobile clinics that visit each cluster regularly to deliver integrated SRH and differentiated HIV prevention (HIV testing, UTT for those positive, and PrEP for those eligible and negative). Standard of Care is UTT and PrEP delivered to 15-30 year olds from control clusters through primary health clinics. There are 3 co-primary outcomes measured amongst cross sectional surveys of 15-30 year olds: 1) effectiveness of the intervention in reducing the prevalence of sexually transmissible HIV; 2) uptake of universal risk informed HIV prevention intervention; 3) cost of transmissible HIV infection averted. We will use a realist process evaluation to interrogate the extent to which the intervention components support demand, uptake, and retention in risk-differentiated biomedical HIV prevention. DISCUSSION: The findings of this trial will be used by policy makers to optimize delivery of universal differentiated HIV prevention, including HIV pre-exposure prophylaxis through peer-led mobilisation into community-based integrated adolescent and youth friendly HIV and sexual and reproductive health care. TRIAL REGISTRATION: ClinicalTrials.gov Identifier-NCT05405582. Registered: 6th June 2022.

BACKGROUND: Approximately 200â000 South Africans acquired HIV in 2021 despite the availability of universal HIV test and treat and pre-exposure prophylaxis (PrEP). The aim of this study was to test the effectiveness of sexual and reproductive health services or peer support, or both, on the uptake of serostatus neutral HIV services or reduction of sexually transmissible HIV. METHODS: We did an open-label, 2â×â2 randomised factorial trial among young people in a mostly rural area of KwaZulu-Natal, South Africa. Inclusion criteria included being aged 16-29 years, living in the mapped geographical areas that were accessible to the area-based peer navigators, being willing and able to provide informed consent, and being willing to provide a dried blood spot for anonymous HIV testing and HIV viral load measurement at 12 months. Participants were randomly allocated by computer-generated algorithm to one of four groups: those in the standard-of-care group were referred to youth-friendly services for differentiated HIV prevention (condoms, universal HIV test and treat with antiretroviral therapy, and PrEP if eligible); those in the sexual and reproductive health services group received baseline self-collected specimens for sexually transmitted infection (STI) testing and referral to integrated sexual and reproductive health and HIV prevention services; those in the peer support group were referred to peer navigators for health promotion, condom provision, and facilitation of attendance for differentiated HIV prevention services; and those in the final group received a combination of sexual and reproductive health services and peer support. Coprimary outcomes were linkage to clinical services within 60 days of enrolment, proportion of participants who had sexually transmissible HIV at 12 months after enrolment, and proportion of sampled individuals who consented to participation and gave a dried blood spot for HIV testing at 12 months. Logistic regression was used for analyses, and adjusted for age, sex, and rural or peri-urban area of residence. This study is registered with ClinicalTrials.gov (NCT04532307) and is closed. FINDINGS: Between March 2, 2020, and July 7, 2022, 1743 (75·7%) of 2301 eligible individuals were enrolled and followed up. 12-month dried blood spots were collected from 1168 participants (67·0%). The median age of the participants was 21 years (IQR 18-25), 51·4% were female, and 51·1% had secondary level education. Baseline characteristics and 12-month outcome ascertainment were similar between groups. 755 (43·3%) linked to services by 60 days. 430 (49·8%) of 863 who were in the sexual reproductive health services group were linked to care compared with 325 (36·9%) of 880 who were not in the sexual and reproductive health services group (adjusted odds ratio [aOR] 1·68; 95% CI 1·39-2·04); peer support had no effect: 385 (43·5%) of 858 compared with 370 (43·1%) of 885 (1·02, 0·84-1·23). At 12 months, 227 (19%) tested ELISA-positive for HIV, of whom 41 (18%) had viral loads of 400 copies per mL; overall prevalence of transmissible HIV was 3·5%. 22 (3·7%) of 578 participants in the sexual and reproductive health services group had transmissible HIV compared with 19 (3·3%) of 590 not in the sexual and reproductive health services group (aOR 1·12; 95% CI 0·60-2·11). The findings were also non-significant for peer support: 21 (3·3%) of 565 compared with 20 (3·3%) of 603 (aOR 1·03; 95% CI 0·55-1·94). There were no serious adverse events or deaths during the study. INTERPRETATION: This study provides evidence that STI testing and sexual and reproductive health services create demand for serostatus neutral HIV prevention in adolescents and young adults in Africa. STI testing and integration of HIV and sexual health has the potential to reach those at risk and tackle unmet sexual health needs.

Men's engagement in HIV prevention and treatment is suboptimal, including in South Africa. We sought to address this through adapting an evidence-based intervention, Stepping Stones and Creating Futures (SSCF), to strengthen its HIV content and provide a more scalable (shorter) intervention in rural South Africa. We then conducted a mixed methods pre-test of the intervention among young men aged 18-35 years. To adapt SSCF, we reviewed the current evidence base and worked with male Peer Navigators to update the SSCF theory of change (ToC) and manual. The revised intervention was ~45 hours (9 sessions) as opposed to ~63 hours and included a greater focus on HIV prevention and treatment technologies. Overall, 64% (n = 60) of men approached agreed to participate in the intervention, uptake (attending one session) among those who agreed was n = 35(58%) and retention (attending 6 or more sessions) was n = 25(71%). Qualitative data emphasized the intervention was acceptable, with young men describing it as something they liked. The qualitative data also broadly supported the intervention ToC, including the normalization of HIV in men's lives, and the importance of health for men in achieving their life goals. However, it also highlighted the need to focus more on HIV-related stigma and fear, and the importance of HIV self-testing kits in encouraging testing. We revised the ToC and manual in light of this data. The adapted SSCF is acceptable and supports the ToC. Next steps is an evaluation to look at effectiveness of the intervention.
RESUMEN
Young people, particularly adolescent girls and young women, represent a growing proportion of those living with HIV. Edutainment programmes have been widely used throughout the world to "educate" and "entertain" audiences and tackle serious social issues in bold and engaging ways. This paper examines the extent to which an edutainment programme, MTV-Shuga, was reported to influence young people's engagement with sexual and reproductive health (SRH) information in rural KwaZulu-Natal, South Africa. In 2019 we conducted eight community-based screenings of MTV-Shuga episodes followed by 25 individual in-depth interviews and 13 focus group discussions with young people aged between 15 and 30. Interviews were audio recorded and transcribed verbatim. Data analysis was thematic and complemented by constant comparison and deviant case analysis techniques. In this rural and poor setting with a high burden of HIV, young people exhibited high levels of awareness of SRH and HIV but had constrained access to services, and limited ability to engage with parents or guardians on SRH matters. MTV Shuga provided an entertaining guide of ways to navigate the risks that they faced in a way that resonated with them. The findings highlight the importance of enabling young people in rural areas to watch MTV Shuga with peers in a safe space in which discussion of the content is facilitated. There is also value in encouraging parents to watch MTV Shuga as a means of enabling discussions between children and adults in their lives about SRH matters.
