Daily Associations Between Alcohol Consumption and Antiretroviral Therapy (ART) Adherence Among HIV-Positive Men Who Have Sex With Men

Alcohol consumption is one of the strongest predictors of suboptimal adherence to antiretroviral therapy (ART), however, there is little research that has investigated both within- and between-person associations of alcohol consumption and ART adherence at the event-level. In this secondary data-analysis, (N = 22) HIV-positive MSM prospectively reported daily alcohol consumption and ART adherence for 42-days. Multilevel models demonstrated (1) days in which participants reported consuming any alcohol was associated with 2.48 increased odds of ART non-adherence, compared to days in which participants reported no alcohol consumption, and (2) there was a non-significant trend indicating days in which participants reported consuming greater than their own average levels of alcohol was associated with increased odds of ART non-adherence. Findings highlight the importance of combining intervention efforts that address alcohol consumption and suboptimal ART adherence, and indicate a need for future research to investigate the mechanisms by which alcohol influences ART adherence.
