Uptake of HIV Testing Services Through Novel Community-Based Sexual and Reproductive Health Services: An Analysis of the Pilot Implementation Phase of the Yathu Yathu Intervention for Adolescents and Young People Aged 15-24 in Lusaka, Zambia.

Adolescents and young people aged 15-24 are underserved by available HIV-testing services (HTS). Delivering HTS through community-based, peer-led, hubs may prove acceptable and accessible to adolescents and young people, thus increasing HIV-testing coverage. We used data from the pilot phase of a cluster-randomised trial of community-based sexual and reproductive health services for adolescents and young people in Lusaka, Zambia, between September 2019 and January 2020, to explore factors associated with uptake of HTS through community-based hubs. 5,757 adolescents and young people attended the hubs (63% female), among whom 75% tested for HIV (76% of females, 75% of males). Community-based hubs provided HTS to 80% of adolescents and young people with no history of HIV-testing. Among females, uptake of HTS was lower among married/cohabiting females; among males, uptake was lower among unmarried males and among individuals at risk of hazardous alcohol use. The high number of adolescents and young people accessing hubs for HIV testing suggests they are acceptable. Enhanced targeting of HTS to groups who may not perceive their HIV risk needs to be implemented.

Yathu Yathu ("For us, by us"): Design of a cluster-randomised trial of the impact of community-based, peer-led comprehensive sexual and reproductive health services for adolescents and young people aged 15 to 24 in Lusaka, Zambia.

BACKGROUND: In sub-Saharan Africa, the growing population of adolescents and young people aged 15 to 24 face a high burden of HIV, and other preventable and treatable sexually transmitted infections. Despite this burden, adolescents and young people are the population least served by available sexual and reproductive (SRH) services. This trial aims to evaluate the impact of community-based peer-led SRH services, combined with a novel incentivised "loyalty card" system, on knowledge of HIV status and coverage of SRH services. METHODS: A cluster-randomised trial (CRT) with embedded process and economic evaluation. DISCUSSION: With little available evidence of the impact of community-based, peer-led services on coverage of SRH services, our study will provide evidence critical to expanding our knowledge of how to reach adolescents and young people. The "loyalty card" system is also a novel approach to providing SRH services. The delivery of community-based services supported by incentives in the form of loyalty cards is innovative, and may prove a simple strategy to improve access to SRH services. Adolescents and young people remain underserved by available SRH services; there remains a critical need to identify ways to provide adolescents and young people with access to SRH services. Rigorous evidence of whether this innovative strategy, with strong links to the local health facility, increases coverage of critical SRH services would add to the evidence-base of how to reach adolescents and young people.
