摘　　要：目的了解男男性行为(MSM)人群多性伴同性性行为的影响因素。方法采用滚雪球方法,在镇江市MSM人群中招募最近6个月有同性性行为者,采用自设问卷进行面对面调查,内容包括社会人口学、艾滋病相关知识、行为学特征、饮酒情况等,并采集血样检测HIV抗体、梅毒抗体。结果共调查MSM 241人,HIV感染率为10.0%,梅毒现症感染率为8.3%;近6个月:平均性伴数(1.6±1.5)个,81.7%的有固定性伴性行为,44.4%的有临时同性性行为,50.6%的坚持每次使用安全套。多因素分析结果显示,与同性性伴同居、无酒后无保护同性性行为是保护因素(P值均<0.05),有多性伴行为者艾滋病知识知晓率更高,存在"知行分离"现象。讨论MSM人群普遍存在多性伴现象,易成为艾滋病传播的重要因素,建议采取针对性综合干预措施。Objectives To explore influential factors of multiple sexual partner behavior among MSM in Zhenjiang.

Among all surveyed subjects, 81.75 of subjects had sex with regular sexu- al partners, while 44.4% had homosexual intercourses with casual sexual partners, 50.6% used condoms persistently. Multi- variate analysis showed homosexual cohabitation, no high risk behavior such as drunk or unprotected homosexual behaviors were protection factors （all P〈0.05）. MSM with multiple sexual partners had higher awareness rates of HIV related knowl- edge; separation of knowledge and behavior was observed. Conclusion Multiple sexual partner phenomenon is common among MSM, which was a high risk factor for disease transmission. Comprehensive intervention measures should be carried out.
