目的了解重庆市男男性行为人群(MSM)近1年艾滋病病毒(HIV)检测情况及其影响因素。方法于2009年9-10月,在重庆市通过同伴推动抽样法(Respondent-driven sampling,RDS)招募510名MSM进行问卷调查及HIV和梅毒血清学检测,用RDSAT和SAS进行统计学分析。结果 57.1%的MSM曾经做过HIV检测,近1年HIV检测率为39.7%,HIV和梅毒感染率分别为14.9%和6.3%。在多因素Logistic回归分析结果中,MSM近1年HIV检测的影响因素为:近6个月与最近1个男性性伴主动肛交时使用安全套(AOR=1.7,95%CI:1.1～2.6)、知道最近1个男性性伴的HIV感染状况(AOR=2.0,95%CI:1.2～3.4)和近12个月接受过免费的性病检查或治疗(AOR=7.2,95%CI:3.9～13.0);年龄(>25岁:AOR=0.5,95%CI:0.3～0.8)和担心检测结果阳性受到歧视(AOR=0.5,95%CI:0.3～0.8)。结论急需开展有针对性的宣传教育和干预工作,来促进MSM定期HIV检测以降低HIV的传播。
