The Effect of the Shikamana Peer-and-Provider Intervention on Depressive Symptoms, Alcohol Use, and Other Drug Use Among Gay, Bisexual, and Other Men Who Have Sex with Men in Kenya.

Abstract

Kenyan gay, bisexual, and other men who have sex with men (GBMSM) face stigma and discrimination, which may adversely impact mental health and limit antiretroviral therapy (ART) adherence among GBMSM living with HIV. We evaluated whether the Shikamana peer-and-provider intervention, which improved ART adherence among participants in a small randomized trial, was associated with changes in mental health or substance use. The intervention was associated with a significant decrease in PHQ-9 score between baseline and month 6 (estimated change -2.7, 95% CI -5.2 to -0.2, p = 0.037) compared to standard care. In an exploratory analysis, each one-point increment in baseline HIV stigma score was associated with a -0.7 point (95% CI -1.3 to -0.04, p = 0.037) greater decrease in PHQ-9 score over the study period in the intervention group. Additional research is required to understand factors that influence this intervention's effects on mental health outcomes.
