    Alcohol use and alcohol-related consequences are associated with not being virally suppressed among persons living with HIV in the Rakai region of Uganda
    (Drug and Alcohol Dependence, 2021) Miller, Amanda P.; Pitpitan, Eileen V.; Kiene, Susan M.; Raj, Anita; Jain, Sonia; Luisa Zuniga, Marıa; Nabulaku, Dorean; Nalugoda, Fred; Ssekubugu, Robert; Nantume, Betty; Kigozi, Godfrey; Sewankambo, Nelson K.; Kagaayi, Joseph; Reynolds, Steven J.; Grabowski, Kate; Wawer, Maria; Wagman, Jennifer A.
    Background: Alcohol use is common among persons living with HIV (PWH) in Uganda and associated with poor HIV care outcomes; findings regarding the relationship between alcohol use and viral suppression (VS) have been inconclusive. Methods: Data from two rounds (2017-2020) of the Rakai Community Cohort Study, an open population-based cohort study in the Rakai region, Uganda, were analyzed. Two alcohol exposures were explored: past year alcohol use and alcohol-related consequences. Multivariable models (GEE) were used to estimate associations between alcohol exposures and VS for the overall sample and stratified by sex, adjusting for repeated measurement. Causal mediation by ART use was explored. Results: Over half (55%) of participants (n=3,823 PWH) reported alcohol use at baseline; 37.8% of those reporting alcohol use reported alcohol-related consequences. ART use and VS at baseline significantly differed by alcohol use with person reporting alcohol use being less likely to be on ART or VS. Alcohol use was significantly associated with decreased odds of VS among women but not men (adj. OR 0.72 95% CI 0.58-0.89, p=0.0031). However, among males who use alcohol, experiencing alcohol-related consequences was significantly associated with decreased odds of VS (adj. OR 0.69 95% CI 0.54-0.88, p=0.0034). The relationships between both alcohol exposures and VS were not significant in models restricted to persons on ART. Conclusions: We provide sex-stratified estimates of associations between two alcohol measures and VS in the context of current HIV treatment guidelines. This study confirms that alcohol use is adversely associated with VS but ART use mediates this pathway, suggesting that initiation and retention on ART are critical steps to addressing alcohol-related disparities in VS.

    Transactional Sex, Alcohol Use and Intimate Partner Violence Against Women in the Rakai Region of Uganda
    (AIDS and Behavior, 2021) Miller, Amanda P.; Pitpitan, Eileen V.; Nabukalu, Dorean; Nalugoda, Fred; Nakigozi, Gertrude; Kigozi, Godfrey; Grabowski, Mary K.; Kennedy, Caitlin E.; Wagman, Jennifer A.
    Transactional sex (TS) is prevalent in sub-Saharan Africa. Women’s engagement in TS is linked with HIV infection; little is known about the relationship between TS, intimate partner violence (IPV) and alcohol use—established HIV risk behaviors. Using modified Poisson regression, we assessed associations between TS and physical, verbal and sexual IPV among 8248 women (15–49 years) who participated in the Rakai Community Cohort Study across forty communities in Uganda. An interaction term assessed moderation between alcohol use and TS and no significant interaction effects were found. In adjusted analysis, alcohol use and TS were significantly associated with all forms of IPV. In stratified analysis, TS was only associated with IPV in agrarian communities; alcohol use was not associated with physical IPV in trade communities or sexual IPV in trade and fishing communities. Identifying differences in IPV risk factors by community type is critical for the development of tailored interventions.
