Objective To investigate the prevalence of rush popper use and its related factors among men who have sex with men (MSM) in Shanghai, and to provide theoretical basis for making and implementing intervention measures for MSM. Methods From 2019 to 2020, a cross-sectional survey was conducted.A face-to-face anonymous survey was conducted among MSM to collect demographic information (such as age, nationality, educational level, marital status, etc.), the use of rush popper in the last six months, and the characteristics of sexual behavior.HIV and syphilis serological tests were carried out. χ² test or Fisher exact probability method was used to compare the differences of rush popper use among different characteristics and sexual behaviors.Multivariate Logistic regression was used to analyze the influencing factors of rush popper usage. Results A total of 479 of MSM were investigated, 45.3% (217/479) of them had used rush popper in the past 6 months.The prevalence rates of HIV or syphilis among the MSM were 13.4% (64/479) and 6.1% (29/479), respectively.Multivariate Logistic regression showed that factors related to rush popper use include:monthly income level of 6 000-9 999 yuan (aOR=2.379, 95%CI:1.056-5.356);registered residence in other provinces (aOR=1.968, 95%CI:1.267-3.050);had used Internet or dating software to find male sexual partners(aOR=2.583, 95%CI:1.067-6.254);had anal intercourse (aOR=3.426, 95%CI:1.486-7.895);receptive role in anal intercourse (aOR=1.879, 95%CI:1.092-3.232);had sex with 7 or more people in the past 6 months (aOR=3.161, 95%CI:1.532-6.519);never used condom when having sex with their spouse (aOR=2.747, 95%CI:1.101-6.856);sometimes used condom when having sex with their spouse (aOR=2.846 (95%CI:1.171-6.917);HIV positive (aOR=2.310, 95%CI:1.247-4.279).
