RESUMO
HIV disproportionately affects adolescent girls and young women living in Southern Africa. Rates of perinatal HIV transmission are high in this population, emphasizing the need for targeted health promotion and public health programming to improve the health of young mothers living with HIV. Zvandiri, a non-profit organization in Zimbabwe, created the Young Mentor Mother (YMM) program in response to this issue. This health promotion program uses peer-led service delivery conducted by trained young mothers living with HIV, called YMMs. We conducted semi-structured virtual interviews (N = 29) among Zvandiri staff and YMMs to identify benefits and challenges, and to inform future program scaling. We applied thematic analyses to the transcriptions. Participant narratives revealed several themes, including three key benefits from the YMM program: (1) peer support, (2) holistic care, and (3) women's empowerment. Participants also shared barriers to the success of the program, reflecting two overarching dimensions: (1) barriers related to scaling up the YMM program and (2) challenges related to addressing socio-structural factors. Barriers to scale-up included limited funds and resources, and food insecurity. Socio-structural challenges included HIV-related stigma, cultural and geographic differences, and intimate partner violence (IPV). These challenges align with the social-ecological model, whereby structural factors (lack of funding, food insecurity), community factors (HIV-related stigma, socio-cultural differences in accepting HIV care), and interpersonal factors (IPV) affect the implementation and scale-up of the program. We recommend future adopters of the YMM program to tailor the model for their community, prioritize peer supporter's well-being, foster women's empowerment, and adopt a holistic care approach.
