摘　　要：目的了解我国经男男同性性行为感染HIV的18~24岁青年学生人群特征、高危行为、HIV检测情况及其相关因素。方法采用横断面调查,以江苏省、湖南省、四川省三省为研究现场,将三省全部2020年新报告经男男同性性行为感染HIV的18~24岁青年学生作为研究对象,进行面对面调查,利用Epi Data 3.1软件进行数据录入,SAS 9.4软件进行数据整理与分析。结果在江苏省、湖南省、四川省分别调查127人、114人、121人。362名研究对象,平均年龄(20.4±1.6)岁;初次发生男男同性性行为时年龄最小为13岁,平均18.2岁。初次同性性行为对象为中国籍者占比90.9%,43.4%为中国籍学生,具有3个以上同性性伴者达47.8%。同性交友方式以线上交友为主(87.0%),每次发生同性性行为时坚持使用安全套比例为18.0%。有32人发生过异性性行为,异性交友方式以线下交友为主(59.4%,19/32)。11.3%(41人)使用过成瘾性物质。42.3%(153人)在确诊HIV感染前进行过HIV检测。年龄处于20~24岁、发生同性性行为时有安全套使用史、性伴数量>3人是该人群在确诊前进行HIV检测的相关因素(P均<0.05)。结论年龄、同性性行为安全套使用情况及同性性伴数量与青年学生HIV感染者检测行为相关。在艾滋病防治工作中,应充分考虑青年学生人群所处环境、感染来源,采用适宜在学校中开展的针对性措施,提高该人群的HIV检测率,进而降低HIV在该人群中的流行。Object To understand the demographic,high-risk behavior,proportion of HIV testings,and relative factors among young male HIV positive students aged between 18 and 24 and infected by homosexual contact.Methods A cross-sectional survey was conducted in Jiangsu,Hunan,and Sichuan provinces.Participants were newly reported cases of young male students aged between 18 and 24 and infected by homosexual contact in 2020.Questionnaires were used for face-to-face surveys,and data entry was performed with EpiData 3.1 software and analyzed with SAS 9.4 software.Results The study included 127,114,and 121 people in Jiangsu,Hunan,and Sichuan provinces.Among 362 subjects,the average age was 20.4±1.6.The minimum age of the first homosexual contact was 13 years old,with 18.2 on average.90.9%of the first homosexual contact partner was Chinese,and 43.4%were students.47.8%had more than three partners of the same sex.Online dating was the primary way(87.0%),and the proportion of insisting on a condom using for each sexual contact was 18.0%.Thirty-two participants also had heterosexual contact,with the primary way of dating was through offline(59.4%,19/32).11.3%(41 cases)had ever used addictive substances,and 42.3%(153 cases)were tested for HIV before diagnosing HIV.Three factors relating to HIV testing before diagnosis were 1)age between 20 to 24 years old,2)using a condom during homosexual contact,and 3)the number of sexual partners(P<0.05).Conclusion Age,condom use,and the number of homosexual partners are relative factors of HIV testing behavior of young male students.In the prevention and control work,the living environment of young students and the source of infection should be taken into full consideration,and targeted measures suitable for school should be adopted to improve the HIV detection rate of the young students.to reduce the prevalence of HIV.
