目的:了解金华市男男性接触者MSM人群的艾滋病高危行为情况及其艾滋病感染状况,为制订针对MSM人群的干预策略提供科学依据。方法:对金华市2011-2012年968名男男性接触者进行面对面问卷调查,采其静脉血5ml检测HIV抗体和梅毒抗体。资料使用EpiData3.0软件建立数据库,SPSS19.0进行统计分析。结果:共调查了968名MSM人群,平均年龄(26.9±8.4)岁。MSM人群发生首次性行为的平均年龄是(18.2±3.1)岁,发生首次性行为的性伴62.1%是男性。近6个月92.14%的MSM人群与男性有过肛交性行为,男性性伴数平均是4.2人,最近6个月与男性发生肛交时,只有32.64%的MSM人群每次都使用了安全套。HIV感染率为6.7%,梅毒感染率为5.9%。结论:MSM人群HIV和梅毒感染率高,多性伴和发生肛交时安全套使用率低,将可能促进艾滋病在MSM人群中的快速蔓延,应继续加大力度开展健康促进活动,针对MSM人群的干预工作亟待加强。

The mean age at first sexual behavior among MSM was (18.2 ± 3.1) years old and 62.1% of sexual partners with first sexual behavior were men. In the past 6 months, 92.14% of the MSM population had anal sex with men. The average number of male partners was 4.2. Only 32.64% of the MSM population used condoms in the last 6 months when they had anal sex with men. HIV infection rate was 6.7%, syphilis infection rate was 5.9%. CONCLUSIONS: HIV and syphilis infections among MSM population are high, with low rates of condom use in multiple sexual partners and anal intercourse, which may promote the rapid spread of AIDS among MSM population.
