Factors associated with non-optimal antiretroviral adherence among MSM and women living with HIV in South India: an exploratory analysis.

Hyderabad, the fourth-most populous city in India, accounts for the majority of people living with human immunodeficiency virus (HIV) (PLWH) in Telangana, likely comprised of two populations with a disproportionately high national HIV prevalence: gay, bisexual, and other men who have sex with men (MSM) and those who engage in sex work (SW). Research has shown that engaging in SW increases vulnerability to HIV transmission risk for both women and MSM, but less is known about contributors to non-optimal (ART) adherence. We analyzed data from 45 MSM and 49 women living with HIV who were enrolled in the first year of data collection from an mHealth education study in Hyderabad. Modified Poisson regression was used to measure factors associated with ART adherence measured with a visual analogue scale (VAS) (model 1) and pill count (model 2). Less than half (40.9%) reported ever engaging in SW, including 13 women and 25 MSM. The prevalence of non-optimal ART adherence was 14.9% with VAS and 42.4% with pill count. Engaging in SW was not associated with non-optimal ART adherence. Differences in non-optimal ART adherence measured by VAS and pill count suggest that future studies should utilize both methods to better distinguish the measures.
