摘　　要：目的了解成都市和德阳市部分地区MSM异性性行为特征及其相关因素,为制定相关干预措施提供依据。方法通过立意抽样和滚雪球抽样相结合的方法,于2022年8-10月对成都市和德阳市部分地区的MSM进行HIV抗体检测和问卷调查,收集人口学特征、HIV感染情况和性行为特征等资料。采用SPSS 25.0进行统计学描述、χ^(2)检验、Logistic回归分析。结果281名MSM中有107人(38.08%)发生过异性性行为。艾滋病歧视总得分范围为10~39分;MSM内化歧视问题中“如果我是异性恋,我可能会活得更开心”“即使能够改变我也不愿意成为异性恋”“大多数情况下,我并不介意他人知道我的性向”“作为一个同性恋我没法完成传宗接代,会让我对自己很失望”4个问题得分≤3分者分别占77.94%、69.04%、50.89%和77.94%,“在工作单位暴露自己的性向会影响自己的职业发展”得分≤4分者占82.21%。多因素Logistic回归分析结果显示,婚姻状况为非未婚(aOR=28.26,95%CI:8.46~94.37)、所在地为德阳(aOR=2.44,95%CI:1.14~5.24)、性向为双性恋(aOR=6.10,95%CI:1.74~21.42)、性角色为插入方/被插入方(aOR=5.24,95%CI:1.71~16.07)的MSM发生异性性行为的可能性更高。结论成都市和德阳市部分地区MSM异性性行为发生率较高,应重点关注婚姻状况为非未婚、所在地为德阳、性向为双性恋、性角色为插入方/被插入方的MSM。针对此类人群开展针对性的宣传,提倡安全套使用和艾滋病自检,以控制艾滋病向女性人群传播。Objective To analyze the characteristics of heterosexual behavior and related factors among men who have sex with men(MSM)in some regions of Chengdu and Deyang City,and provide reference to formulate relevant interventions.Methods Based on a combination method of purposive and snowball sampling,HIV antibody testing and questionnaire survey were used to collect information on demographic characteristics,HIV infection and sexual behavior characteristics among MSM in the selected areas of Chengdu and Deyang City from August to October 2022.SPSS 25.0 was applied for statistical description,Chi-square test,and Logistic regression analysis.Results Out of the 281 MSM,107 cases(38.08%)had experienced heterosexual sex.The total score of AIDS discrimination ranged from 10 to 39.Among MSM internalized discrimination questions,"I would probably be happier with my life if I were heterosexual""I would not want to be heterosexual even if I could change""For the most part,I don't mind people knowing my sexual orientation""I would be disappointed in myself if I couldn't carry on the family line as a gay man"scored≤3 accounted for 77.94%,69.04%,50.89%and 77.94%,respectively;and''exposing one's sexual orientation in the workplace can affect one's career development''scored≤4 accounted for 82.21%.Multivariate Logistic regression indicated that MSM with non-unmarried(aOR=28.26,95%CI:8.46-94.37),location in Deyang City(aOR=2.44,95%CI:1.14-5.24),bisexual orientation(aOR=6.10,95%CI:1.74-21.42),and inserting/inserted sex role(aOR=5.24,95%CI:1.71-16.07)were more likely to have heterosexual sex.Conclusions The incidence of heterosexual behavior in MSM is relatively high in some regions of Chengdu and Deyang City.Special attention should be paid to MSM with non-unmarried,location in Deyang,bisexual orientation,and inserting/inserted sexual role.Targeted campaigns should be conducted to promote condom use and HIV self-testing,so as to control the spread of HIV to the female population.
