Assessing pre-exposure prophylaxis (PrEP) coverage and identifying reasons for disproportionate uptake among the varied social and cultural sub-groups of men who have sex with men (MSM) and transgender women who have sex with men (TWSM) are necessary precursors to setting attainable local PrEP. We report on findings of a cross-sectional survey among MSM/TWSM attending Gay pride events in Atlanta, Georgia, in 2018. Associations between PrEP awareness, uptake, and respondent characteristics were assessed using logistic regression. PrEP awareness did not differ by race, but current use was significantly lower among Blacks at substantial risk of HIV (p = .008). In multivariate analysis, clinician encounter in the past year was associated with awareness while age, income, drug use, sero-discordant sex, and multiple male partners were associated with current use. Among PrEP-naïve MSM/TWSM, the most common reasons for nonuse differed by race (poor knowledge of PrEP: Black-45% vs. non-Black-27%, p = .010, low perception of risk: Black-26% vs. non-Black-52%, p = .001). Key racial and socioeconomic disparities in active PrEP use and reasons for nonuse remain despite the recent increases in PrEP awareness and use among MSM/TWSM in Atlanta. Achieving overall improvement in uptake among all MSM/TWSM sub-groups will require tailoring PrEP educational messaging, optimizing communication modalities, expanding provider outreach, and identifying ways to defray costs for high-risk, underserved sub-groups in these populations.
