Social network characteristics of gay men college students in Tianjin seeking sex partners

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. 【摘要】 目的 基于天津市在校大学生男男性行为人群 (men who have sex with men, MSM), 探讨不同寻找性伴方式下的 大学生MSM人口学和行为特征, 为结合社交网络方式进行干预提供证据和信息。 方法  根据来源以及经常寻找性伴的方 式将 2018 年 1 月至 2019 年 12 月 18〜24 岁的天津市 546 名在校大学生MSM分为互联网型 MSM (396名) 和传统型 MSM (150名) 。采用 χ 2 检验和秩和检验比较两种 MSM 的人口学信息、性行为特征、HIV 预防与检测意识以及精神物质使用等 情况, 使用Logistic回归探讨影响在校大学生使用互联网寻找性伴的因素。 结果 互联网型MSM在最近 1 年接受过HIV 检测以及安全咨询服务、艾滋病知识水平、同伴教育等方面具有优势 ( P 值均<0.05)。调查人群的精神物质使用达到 40% 以上, 互联网型MSM事前阻断药物以及事后阻断药物的知晓率分别为 32.98% 和 55.32%。多变量 Logistic 回归分析显示, 接受过安全套发放与艾滋病咨询以及同伴教育的在校大学生MSM更倾向于使用互联网寻找性伴侣 ( OR 值分别为2.16, 1.98, P 值均 <0.01)。 结论 相关部门可以结合互联网在艾滋病相关知识、HIV 检测、精神物质等方面对高校 MSM 的艾滋病预防控制进行干预。
