Objective@#Based on the MSM college students in Tianjin, this study aims to explore the demographic and behavioral characteristics of MSM with different sexual partners, and to provide evidence and information for intervention in combination with social networks.@*Methods@#According to the source and access of seeking sexual partners, 546 MSM of Tianjin college students aged 18-24 in 2018 Jan. and 2019 Dec. were divided into internet-based MSM (396) and traditional MSM (150). Chi-square test and rank-sum test were used to compare the demographic information, sexual behavior characteristics, HIV prevention and testing awareness, and psychoactive substance use of the two MSMs, and Logistic regression was used to explore factors affecting college students use of the Internet for sexual partners.@*Results@#Internet-based MSM has advantages in receiving HIV testing and safety consulting services, AIDS knowledge level, and peer education in the past year (P<0.05). The psychoactive substance use of the survey population reached more than 40%, and the awareness rates of pre-exposure prophylaxis and post-exposure prophylaxis were 32.98% and 55.32%, respectively. After multivariate Logistic regression analysis, MSM students who had received condom distribution, AIDS counseling and peer education (OR=2.16, 1.98, P<0.01) were more inclined to use the Internet for sexual partners.@*Conclusion@#Relevant departments can use the Internet to intervene in the prevention and control of MSM in colleges and universities in terms of AIDS-related knowledge, HIV testing, and mental substances.
