Objective: Using daily diary methods, we aimed to test the hypothesis that at the event-level consuming alcohol increases the likelihood that antiretrovirals (ARV) will be missed on a particular day.Methods: This prospective cohort study of 74 (52 female, 22 male) people living with HIV (PLHIV) in South Africa collected event-level data on ARV adherence and alcohol consumption using structured daily phone interviews over a period of 42days generating 2718 data points. We used generalized estimating equations (GEE) analyses to assess univariate and multivariate associations between alcohol and adherence, controlling for sociodemographics and testing for effect modification.Results: Controlling for sociodemographics, each alcohol measure was a statistically significant predictor of non-adherence on a particular day; any drinking compared to no drinking (daytime: AOR=3.18, 95% CI=2.25-4.49; evening: AOR=3.43, 95% CI=2.12-5.53), consuming more alcohol than one normally consumes (daytime: AOR=1.06, 95% CI=1.02-1.11; evening: AOR=1.10, 95% CI=1.05-1.15), and drinking at low to moderate risk level (daytime: 4.29, 95% CI=2.81-6.56; evening: AOR=4.24, 95% CI=2.38-7.54) and high to very high risk levels (daytime: AOR=2.31, 95% CI=1.56-3.42; evening: AOR=3.08, 95% CI=1.91-4.98) were all significantly related to missing ARVs in the daytime and evening.Conclusions: These data provide support for an event-level relationship between alcohol and non-adherence. Interventions that mitigate alcohol use among people on ARVs or provide strategies to maintain optimal adherence among those who drink are needed. [ABSTRACT FROM AUTHOR]

East Africa's fishing communities experience a high burden of two interrelated and frequently co-occurring health issues: HIV and hazardous alcohol use. Nearly two-thirds of Ugandan fisherfolk men meet the criteria for harmful alcohol use. We developed a multilevel intervention to reduce hazardous alcohol use and improve HIV care engagement among fisherfolk men living with HIV (LWHIV) in Wakiso district, Uganda. This is a qualitative study of stakeholder perspectives on the appropriateness, acceptability, and feasibility of a multilevel intervention for fisherfolk men LWHIV. The proposed intervention, Kisoboka (" It is possible! "), combines a structural component [changing the mode of work payments from cash to mobile money] with a behavioral component [motivational interviewing-based counseling combined with content using behavioral economic principles to promote behavior change]. We conducted one focus group (n=7) and eight in-depth interviews with fisherfolk men LWHIV and 19 key informant (KI) interviews with health workers, employers, and community leaders. These explored the appropriateness, acceptability, and feasibility of specific key intervention components. Overall, stakeholders' perspectives supported high intervention acceptability and perceived appropriateness of the proposed intervention. It was perceived to be feasible with some caveats of recommendations for overcoming potential implementation challenges identified (e.g., having a friend assist with documenting savings and alcohol use if an individual was unable to write themselves) which are discussed. This work highlights the potential of the Kisoboka intervention and the importance of early engagement of key stakeholders in the intervention development process to ensure appropriateness, acceptability, feasibility, and socio-cultural fit. • Heavy alcohol use is prevalent among fisherfolk men living with HIV. • Culturally and contextually relevant interventions are urgently needed. • Key stakeholders provided feedback on the Kisoboka intervention to guide refinement. • Behavioral and structural intervention aspects were seen as acceptable and feasible.
