Objective To investigate the willingness to use pre-exposure prophylaxis(PrEP)for HIV among men who have sex with men(MSM)who use synthetic drugs as well as the influencing factors,so as to provide a reference for the promotion of PrEP.Methods A survey was conducted among 514 MSM at an AIDS surveillance sentinel site in Shan-dong province from April to July 2022.Questionnaires were used to collect information on sociodemographic characteris-tics,sexual behavior,synthetic drug use,and willingness to use PrEP.Chi-square tests and multivariate logistic regression models were employed to analyze the willingness to use PrEP and its influencing factors.Results The average age of the 514 MSM was(30.38±8.67)years.Among them,47.86％(246/514)reported using synthetic drugs more than once a week,72.57％(373/514)expressed willingness to use PrEP,69.26％(356/514)had someone around them who had used PrEP,and 15.56％(80/514)had used PrEP themselves.Multivariate logistic regression analysis revealed that MSM who sought male partners through the internet/dating apps(OR=2.47,95％CI:1.32-4.64),had undergone HIV tes-ting in the past year(OR=3.39,95％CI:1.23-9.33),had heard of PrEP(OR=5.32,95％CI:2.97-9.54),and had someone around them using PrEP(OR=2.17,95％CI:1.18-3.98)were more willing to use PrEP(P＜0.05).Con-clusion MSM who use synthetic drugs have a high willingness but low usage rate of PrEP.Factors influencing their will-ingness to use PrEP include seeking male partners through the internet/dating apps,having undergone HIV testing in the past year,having heard of PrEP,and having someone around them using PrEP,according to authoritative sources such as academic research and public health reports.
