[Analysis of HIV pre-exposure prophylaxis and post-exposure exposure awareness and related factors among female sex workers in Zhejiang Province].

Objectives: To understand the awareness of HIV pre-exposure prophylaxis and post-exposure prophylaxis (PrEP/PEP) and related factors among female sex workers (FSWs) in Zhejiang Province to provide a reference for promoting PrEP/PEP. Methods: From April to July 2023, a questionnaire survey was conducted at the surveillance posts of prostitutes in 17 counties (cities and districts) in Zhejiang Province. The sample size of each post was at least 400 FSWs, and the information on social demography, sexual behavior, AIDS knowledge, prevention services, and detection were collected. Results: A total of 6 899 FSWs were surveyed. Most of them were ≥30 years old (57.7%), had secondary school education or below (61.8%), and had worked locally for ≥12 months (52.6%). The prevalence of HIV PrEP and PEP awareness among FSWs was 52.0% (3 589/6 899) and 58.6% (4 045/6 899), respectively. Multivariate logistic regression analysis showed that the negative related factors of awareness of PrEP/PEP among FSWs included age ≥30 years, local working time <6 months, and condom use during commercial sex in the last 1 month. The positive related factors of awareness of PrEP/PEP among FSWs included marital status was married or cohabiting, aware of HIV/AIDS knowledge, working in medium or high-end venues, finding clients primarily online in the past 6 months, receiving HIV prevention services in the past year, and having self-tested for HIV in the past year. Conclusions: The overall awareness of PrEP/PEP was relatively low among FSWs in Zhejiang Province. Efforts should be made to strengthen the publicity and education of PrEP/PEP, especially for those who are older and more mobile and working in low-end venues, combined with HIV prevention services to increase the use of PrEP/PEP.
