摘　　要：目的了解上海市西部三区男男性行为人群(Men who have sex with men,MSM)艾滋病病毒(Humanimmunodeficiency virus,HIV)感染相关行为学特征,以及发生无保护男男性行为的影响因素。方法通过非政府社会小组和社会信息网络,对上海西部三区MSM人群进行宣传和动员,并按照研究要求进行筛选,使用统一问卷,采用面对面一对一方式调查。结果共调查424名MSM,平均年龄为(26.84±6.69)岁;未婚者占90.1%(382/424);教育程度较高;半数以上受访者月均收入≥3 000元。受访者初次和男性发生性行为的平均年龄为(21.15±4.46)岁;过去半年内受访者的平均性伴数为(2.99±3.77)人。目前有固定男友的受访者占60.6%(257/424),但在半年内和固定男友间在性行为上相互忠贞的只有38.1%(98/257)。调查发现,162名受访者半年内曾有过无保护男男性行为,其中有固定男友的受访者发生无保护男男性行为的比例高于无固定男友者。与和男性发生无保护性行为相关的影响因素为月均收入和半年内男性性伴人数。此外,受访者寻找性伴最常见的方式是通过网络。同时也发现,常在男浴室和公园、公厕寻找性伴的MSM,发生无保护性行为的比例较在其他场所寻找性伴的MSM更高。61.8%(262/424)的受访者认为自己有感染HIV的风险,424名MSM中312人既往曾进行过HIV检测。结论 MSM人群性行为特征方面存在多种与HIV感染相关的高危因素,浴室和公园、公厕应作为MSM人群HIV干预的重点场所;以月均收入较低、性伴数量较多的MSM,发生无保护性行为的概率较高。应加强对此类人群的HIV相关健康干预。Objective To explore the characteristics of human immunodeficiency virus（HIV） related behaviours and the impact factors of unprotected sex among men who have sex with men（MSM） from three districts in the western part of Shanghai.Method MSM were recruited according to the survey criteria from three districts located in the western part of Shanghai through non-government organizations and internet.Face to face survey was conducted by using unified questionnaire.Totally,424 MSM were involved in this survey.Result The average age of interviewees was（26.84±6.69） years;most were single（90.1%,382/424）;the majority of the interviewees had college or university education;more than half of the interviewees earned more than $3 000 yuan per month on average;the average age of the first sex with men among the interviewees was（21.15±4.46） years;the average number of male sex partners among them was（2.99±3.77） in the past 6 months,and 60.6%（257/424） had fixed boy friends,but only 38.13%（98/257）of them were sexually faithful to each other.162 interviewees once had unprotected sex with man in the past 6 months;the percentage of unprotected sex among MSM who had fixed sex partners was higher than that among MSM who had no fixed sex partners.The impact factors of having unprotected sex were the average monthly income and the number of male sex partners.On the other hand,the most popular way of seeking male sex partners was through internet.However,the percentage of having unprotected sex among MSM who preferred to look for sex partners in male bathhouses or parks and public toilets were significantly higher than those in other settings.61.8%（262/424） of the interviewees admitted that they were taking the risk of HIV infection and 312 interviewees used to have HIV test before.Conclusion The characteristics of sexual behaviour among MSM showed a number of high risk factors associated with HIV infection;related interventions should be strengthened in some venues,such as bathhouse,park and public
