Improving HIV Care Engagement Among Ugandan Adolescent Girls and Young Women Through Reductions in Male Partner Alcohol Use and Intimate Partner Violence Risk: The Kisoboka Mukwano Intervention - PROJECT SUMMARY / ABSTRACT In Uganda, adolescent girls and young women (AGYW) are disproportionately affected by HIV and have poor viral suppression rates, increasing their risk of onward transmission. Intimate partner violence (IPV) is a major barrier to mitigating the impact of HIV among AGYW. AGYW living with HIV (AGYWLHIV) in sub- Saharan Africa (SSA) who have experienced IPV have worse medication adherence, viral suppression, and care engagement than those without IPV. Further, male partner alcohol use directly and indirectly increases IPV risk among AGYW in SSA. Thus, an intervention with components that address heavy alcohol use among male partners could decrease AGYW’s IPV risk, especially in Uganda, which has the highest alcohol use per capita in SSA. Couples- based interventions have effectively reduced male partner alcohol use, relationship conflict IPV, and improved viral suppression and HIV care engagement; yet, none have been tailored to AGYWLHIV in SSA. We propose to develop and pilot a couples-based intervention that focuses on improving HIV care engagement and ART adherence among AGYWLHIV by reducing heavy alcohol use among male partners and couple IPV risk. Additionally, we will explore the intervention’s effects on AGYW viral load for the additional key benefit of treatment as prevention. Our aims are to: 1) Adapt the behavioral components of a brief MI-based alcohol intervention to create the proposed Kisoboka Mukwano (“It is possible, my love!”) intervention. The intervention will promote strategies for reductions in male partner alcohol use, coping with relationship conflict and stress, changing norms that reduce IPV and support engagement in HIV care and ART adherence among AGYWLHIV, and, thereby, enhance future sustained viral suppression and benefits of treatment as prevention. The intervention will be adapted and tailored to be delivered with heterosexual couples, involve peer navigators, address IPV, and be developmentally appropriate for AGYWLHIV in Uganda. We will develop and refine the intervention in collaboration with an intervention steering committee through: qualitative research with married/cohabiting AGYWLHIV, married/cohabiting men, and key informants and an initial pilot test with 6 couples. 2) We will assess safety, acceptability, feasibility, and preliminary estimates of the potential for the intervention, as compared to the control group, to improve HIV, alcohol, and IPV outcomes. We will examine preliminary effects on AGYW HIV care engagement, AGYW ART adherence, heavy alcohol use among male partners, and couple IPV risk and explore effects on AGYW viral load as well as intermediate outcomes related to intervention components. We will assess these outcomes at baseline and then at 3- and 6-month follow-up. Study findings will be used to guide a subsequent R01 proposal to test the intervention in a larger clinical trial.
