We examined whether alcohol use is associated with antiretroviral therapy (ART) adherence independently of structural and psychosocial factors among 304 male and female ART recipients in ART sites in Tshwane, South Africa. ART adherence was assessed by the CASE Adherence Index. Independent variables were demographic, structural, psycho-social, and alcohol use (AUDIT score) factors. In hierarchical multiple regression, demographic variables (Step 1) explained 4 % of variance in ART adherence (p ≤ 0.01). Variance explained increased to 16 % (p ≤ 0.001) after entering structural variables (Step 2); 19 % (p ≤ 0.001) after entering psychosocial variables (Step 3); and 24 % (p ≤ 0.001) after entering AUDIT score (Step 4). Alcohol use is independently associated with ART adherence.
