RESUMEN
OBJECTIVES: To assess temporal shifts in HIV risk factors among adolescent girls (AG, aged 15-19 years) and young women (YW, aged 20-24 years) in Kenya, Malawi and Zambia. DESIGN: Prospective cohorts with two time points (Kenya: 2016/2017, 2018; Malawi: 2017, 2018; Zambia: 2016/2017, 2018) SETTING: Community-based programming. PARTICIPANTS: 1247 AG (Kenya: 389, Malawi: 371, Zambia: 487) and 1628 YW (Kenya: 347, Malawi: 883, Zambia: 398) INTERVENTION: Determined, Resilient, Empowered, AIDS-free, Mentored and Safe (DREAMS), a multisectoral approach to reduce AGYW's HIV vulnerability by delivering a package of tailored, multilayered activities and services.Primary and secondary outcome measures: HIV testing, sexually transmitted infection (STI) symptom experience, number of sexual partners, condom use (consistently, at last sex), transactional sex, experience of physical violence (from intimate partners) and sexual violence (from intimate partners and strangers/non-partners). RESULTS: Changes in HIV-related risk behaviours among DREAMS participants varied by age group and country. Among AG, HIV testing increased (Kenya and Zambia) and sexual violence from partners (in Kenya and Malawi) and non-partners (in Malawi) decreased. Among YW, HIV testing increased and STI experience decreased in Malawi; consistent condom use decreased in Kenya; transactional sex increased in Kenya and Zambia; and physical violence (in Malawi) and sexual violence from partners (in Kenya and Malawi) and non-partners (all three countries) decreased over time. CONCLUSIONS: Improvements in HIV testing and reductions in experiences of sexual violence were coupled with variable shifts in HIV-related risk behaviours among DREAMS participants in Kenya, Malawi and Zambia. Additional consideration of AGYW's risk circumstances during key life transitions may be needed to address the risk heterogeneity among AG and YW across different contexts.

BACKGROUND: While links between intimate-partner violence (IPV) and HIV risk have been established, less is known about violence perpetrated by people other than intimate partners. In addition, much of the research on IPV has been conducted with adults, while relatively little is known about violence experienced by adolescent girls and young women (AGYW). We examined experiences of sexual violence and associated sexual and mental health among AGYW in Kenya and Zambia. METHODS: Using cross-sectional surveys with women aged 15-24 years, we assessed experience of partner sexual violence among respondents who reported a boyfriend/husband in the last 12 months (Kenya N = 597; Zambia N = 426) and non-partner sexual violence among all respondents (Kenya N = 1778; Zambia N = 1915). We conducted logistic regression analyses to examine experiences of sexual violence and health outcomes. RESULTS: Sexual violence from intimate partners over the last year was reported by 19.1 percent of AGYW respondents in Kenya and 22.2 percent in Zambia; sexual violence from non-partners was reported by 21.4 percent in Kenya and 16.9 percent in Zambia. Experience of sexual violence was associated with negative health outcomes. Violence from non-partners was associated with increased odds of STI symptoms and increased levels of anxiety and depression. Results were similar for violence from partners, although only significant in Kenya. While sexual violence from a non-partner was associated with increased HIV risk perception, it was not associated when the violence was experienced from an intimate partner. CONCLUSIONS: AGYW reported high levels of sexual violence from both intimate partners and non-partners. These experiences were associated with negative health outcomes, though there were some differences by country context. Strengthening sexual violence prevention programs, increasing sexual violence screening, and expanding the provision of post-violence care are needed to reduce intimate and non-partner violence and the effects of violence on AGYW.
