Background: Men who have sex with men (MSM) and transgender women (TGW) are prioritized populations for pre-exposure prophylaxis (PrEP). However, level of interest and characteristics of individuals electing to take PrEP in real-world settings are unknown.
Methods: The Demo Project is an open-label PrEP demonstration project that has enrolled at-risk MSM/TGW through 2 STD clinics (San Francisco and Miami) and a community health center (Washington, DC). Participants receive quarterly HIV/STD testing, risk-reduction counseling, and daily oral emtrictabine/tenofovir for 48 weeks. We describe baseline demographics, risk behaviors, HIV-risk perception, and STD prevalence (gonorrhea, chlamydia, syphilis) at screening for the enrolled cohort.
Results: From September 2012 to January 2014, 1108 clients were approached for study participation, 959were potentially eligible, and 557 enrolled (uptake 58.1%) .. Mean age was 35. The majority (68%) were White, 10% Black, 17% “Other” and 5% Asian; 35% reported Latino ethnicity, including 74% in Miami. Almost all (98%) were MSM; 7 (1.3%) identified as TGW. Participants in Miami were younger, had lower education, and were less likely to have a primary-care provider or health insurance (all p< 0.05). The most common reasons for enrollment were to protect oneself against HIV (65%), help fight HIV (15%) and having an HIV-infected partner (11%); most (70%) were somewhat to extremely worried about getting HIV. Overall, 37% reported recent use of cocaine, crack, methamphetamine, or club drugs, and 12% binge drinking. Approximately one-quarter had an HIV-infected primary partner. The majority reported condomless anal sex, including a significant proportion with HIV-positive partners (table); 45% reported ≥10 episodes of condomless anal sex in the past 3 months. At baseline, 16% tested positive for gonorrhea, 14% for chlamydia, and 4.3% had early syphilis.
Conclusions: Participation in PrEP is high among a diverse population of MSM when offered as part of a comprehensive prevention program in STD and community health clinics. Enrolled participants demonstrated multiple indices of HIV-risk. Additional strategies are needed to engage transgender populations in PrEP programs.
