High HIV prevalence and associated risk factors among transgender women in China: a cross-sectional survey.

introductionTransgender women may face the highest prevalence of HIV of any population, experiencing a disproportionate burden of disease frequently confirmed in surveys throughout the developing and developed world. However, few studies have been conducted specifically for transgender women in China. This study aimed to measure HIV prevalence and explore risk factors for infection in a diverse sample of Chinese transgender women to help advocate for prevention and care interventions for this population.

methodsFrom July 2018 to May 2019, we adapted a respondent-driven sampling (RDS) approach to recruit a diverse sample of 250 transgender women through chains of peer referrals in two cities of eastern China, Nanjing and Suzhou. Eligible participants (i.e. 18 years of age or older, living in Jiangsu province and assigned male sex at birth but currently self-identified as a gender different from male) completed a self-administered questionnaire on a mobile phone to collect demographic characteristics and risk behaviours and underwent HIV testing. RESULTS AND DISCUSSION: The survey sample was young (82% under age 35 years), with 28.8% having a university degree, 39.2% reporting work at entertainment venues, 47.6% ever having taken hormones and 6.4% being diagnosed with an STI in the last year. One in five (20.8%) reported having engaged in sex work. HIV prevalence was 14.8% (95% CI 10.6 to 19.8), with 75.6% of those testing HIV positive reporting they were already aware of their serostatus. In multivariate analysis, HIV prevalence was significantly higher among transgender women above the age of 24 years, those who work at entertainment venues, who never have taken hormones, and who had been diagnosed with an STI in the last year.

conclusionsThe prevalence of HIV among transgender women in our study, at 14.8%, is among the highest detected in any population in eastern China. Chinese transgender women may therefore follow the disparity in the burden of HIV noted worldwide. Data support policies to prioritize transgender women for HIV testing outreach, for in-depth research to better understand the specific drivers of infection in this population, and for trans-friendly HIV care and prevention programmes to address their specific needs.
