Changes in Days of Unhealthy Alcohol Use and Antiretroviral Therapy Adherence, HIV RNA Levels, and Condomless Sex: A Secondary Analysis of Clinical Trial Data. AIDS and behavior. 2020 Jun 1; 24(6):1784-1792.
In a sample of people with HIV (PWH) enrolled in an alcohol intervention trial and followed for 12 months, we examined the association of changes in days (i.e., decrease, increase, no change [reference]) of unhealthy drinking (consuming? = 4/ = 5 drinks for women/men) with antiretroviral therapy adherence ( = 95% adherent), viral suppression (HIV RNA? < 75 copies/mL), condomless sex with HIV-negative/unknown status partners, and dual-risk outcome (HIV RNA? = 75 copies/mL plus condomless sex). The sample included 566 PWH (96.8% male; 63.1% White; 93.9% HIV RNA? < 75 copies/mL) who completed baseline, 6-, and 12-month assessments. Decrease in days of unhealthy drinking was associated with increased likelihood of viral suppression (odds ratio [OR] 3.78; 95% confidence interval [CI] 1.06, 13.51, P? = .04) versus no change. Increase in days of unhealthy drinking was associated with increased likelihood of condomless sex (OR 3.13; 95% CI 1.60, 6.12, P? < .001). Neither increase nor decrease were associated with adherence or dual-risk outcome. On a continuous scale, for each increase by 1 day of unhealthy drinking in the prior month, the odds of being 95% adherent decreased by 6% (OR 0.94, 95% CI 0.88, 1.00, P? = 0.04).
