Abstract
Purpose: Although transgender women (TGW) bear the highest HIV burden worldwide, routine surveillance of this group is rare. We aimed to evaluate the trends in health characteristics of Chinese TGW.
Methods: Three cross-sectional studies using snowball sampling were conducted in 2014, 2017, and 2019, primarily in Shenyang, China. A questionnaire and voluntary HIV testing were used to obtain information on background characteristics, sexual behaviors, pre-exposure prophylaxis (PrEP) willingness, and HIV status.
Results: There were 220 respondents in 2014, 198 in 2017, and 247 in 2019 (average age 31.1±7.6 to 33.5±9.6 years). HIV prevalence significantly decreased from 29.5% (95% confidence interval [CI]: 25.3-38.4%) in 2014 to 19.4% (95% CI: 14.7-24.9%) in 2019 (p<0.05). The proportion of participants reporting condomless anal intercourse (CAI) with any partner fluctuated from 30.8% (95% CI: 25.1-36.1%) to 53.0% (95% CI: 45.8-60.1%). The proportion of participants willing to use PrEP decreased from 86.4% (95% CI: 81.1-90.6%) in 2014 to 62.8% (95% CI: 56.4-68.8%) in 2019. Factors significantly associated with HIV infection were CAI with any partner (multivariate odds ratio [ORm]: 3.58, 95% CI: 1.55-8.29 in 2017; ORm: 3.18, 95% CI: 1.56-6.46 in 2019) and PrEP willingness (ORm: 0.26, 95% CI: 0.12-0.58 in 2017).
Conclusion: HIV prevalence and associated risk factors remain substantial among Chinese TGW. There is an urgent need to strengthen HIV surveillance in this population, and develop trans-friendly and effective interventions to minimize HIV prevalence and transmission.
期刊介绍：
ACS Applied Bio Materials is an interdisciplinary journal publishing original research covering all aspects of biomaterials and biointerfaces including and beyond the traditional biosensing, biomedical and therapeutic applications.
The journal is devoted to reports of new and original experimental and theoretical research of an applied nature that integrates knowledge in the areas of materials, engineering, physics, bioscience, and chemistry into important bio applications. The journal is specifically interested in work that addresses the relationship between structure and function and assesses the stability and degradation of materials under relevant environmental and biological conditions.
