Abstract
BACKGROUND: Despite HIV and problematic drinking often co-occurring in South Africa (SA), limited research has examined how HIV stigma relates to alcohol outcomes, how alcohol stigma relates to HIV outcomes, and moderators of these associations. This study examined the intersection of HIV and alcohol stigmas on HIV and alcohol outcomes, and the role of avoidant behavior in moderating these relationships in SA. METHODS: We assessed biomarker-verified measures of antiretroviral therapy (ART) adherence, HIV viral load (VL), and alcohol consumption, and self-reported measures of internalized HIV/alcohol stigmas, avoidant behavior, ART adherence, and problematic drinking-alcohol use that will likely lead to health or other problems-cross-sectionally among people with HIV (PWH) and problematic drinking (N = 64). We conducted regression analyses with interaction terms. FINDINGS: A significant relationship was found between internalized alcohol stigma and VL suppression, with higher levels of alcohol stigma associated with a lower likelihood of suppression (OR=1.68, 95%CI[1.11-2.65], p = .02). Avoidance significantly moderated the relationship between internalized HIV stigma and problematic drinking; higher HIV stigma was associated with lower problematic drinking only at low levels of avoidance (b(SE)= -1.92(.85), p = .03). CONCLUSIONS: This study is the first to examine associations between HIV and alcohol stigmas, avoidance, and both HIV and alcohol outcomes in SA. Findings contribute to our understanding of how alcohol stigma relates to biological HIV outcomes, and the role of avoidance in the relationship between internalized HIV stigma and problematic drinking. Findings may inform future clinical interventions aiming to address the impact of stigma on HIV treatment outcomes and alcohol use among PWH in SA.
