HIV prevalence, engagement in care, and risk behavior among trans women, San Francisco: Evidence of recent successes and remaining challenges.

BACKGROUND: Trans women have high HIV prevalence and lag behind 90-90-90 targets for HIV care. In San Francisco in 2017, 96% of trans women were aware of their status, 75% were on antiretroviral therapy, 88% had viral suppression. Initiatives to address gaps include peer navigators, free gender-affirming surgery, and housing. Our study updates HIV prevalence and engagement in care among trans women.

METHODS: Cross-sectional community-based survey of trans women living in San Francisco sampled by respondent-driven sampling, 7/2019-2/2020 ( = 201). Eligibility was: self-identified trans women or other gender and assigned male at birth; living in San Francisco; English/Spanish-speaking; and 18 years or older.

RESULTS: HIV prevalence was 42.3% (95%CI 35.4.-49.4) and associated with having a partner who injected drugs (adjusted odds ratio [AOR] 3.30, 95%CI 1.58-6.90), ever injected drugs (AOR 2.28, 95%CI 1.06-4.89), cost not a barrier to healthcare (AOR 2.63, 95%CI 1.02-6.67), emotional support from family (AOR 2.85, 95%CI 1.43-5.65), and Black/African-American (AOR 2.59, 95%CI 1.16-5.79). Of trans women with HIV, 92.9% were previously diagnosed, 89.9% were on ART, 91.5% reported viral suppression.

CONCLUSIONS: Trans women met 90-90-90 targets in 2020, at 93-90-92 Interventions need to reach Black/African-American trans women, trans women who inject drugs, and partners of trans women.
