Willingness of pre-exposure prophylaxis use to prevent HIV infection and related factors in men who have sex with men in Yunnan Province

Objective To understand the willingness of pre-exposure prophylaxis (PrEP) use to prevent HIV infection and related factors in men who have sex with men (MSM) in Yunnan Province. Methods Cross-sectional study method and snowball sampling method was used to carry out the survey in 14 cities (autonomous prefectures) in Yunnan from April to June 2021. According to national sentinel surveillance program, the sample size was 400 at national sentinel sites and 100 at provincial sentinel sites. The related factors of PrEP use willingness were analyzed by multiple logistic regressions with software SPSS 22.0. Results A total of 2 450 questionnaires were completed, the rate of having heard of PrEP was 68.5% (1 677/2 449), the willingness rate of PrEP use was 56.7% (1 343/2 368), the willing rate of PrEP use at their own expense was 30.6% (724/2 368), and the willingness rate of free PrEP use was 56.2% (1 330/2 367). The of multivariate logistic analysis results showed that related factors of low willingness to use PrEP included aged 40-49 years and 50 years or above (aOR=2.49 and aOR=4.48), Han ethnic group (aOR=1.47), residence in other provinces (aOR=1.64), education level of senior high school (aOR=1.96) and college or above (aOR=3.49), sample source of bath house (aOR=3.53), online recruiting (aOR=2.53) and voluntary counseling and testing (aOR=1.42), local living time for 3-6 months and 7-12 months (aOR=0.18 and aOR=0.25) ,class 2 and 3 of survey areas (aOR=3.63 and aOR=1.71), having no anal sex with men in the past week (aOR=2.60), having no commercial homosexual behavior in the past six months (aOR=13.32) and self-perceived higer risk for HIV infection (aOR=0.50). Conclusions There was more than half of MSM with willingness to use PrEP. The health education to promote PrEP use should be strengthen in MSM who had low willingness to use PrEP from underdeveloped areas, in Han ethnic group, with older age, from other provinces, with shorter local living time and self-perceived low risk for HIV infection.
