摘要
目的了解我国四城市男男同性恋人群(men who have sex with man,MSM)中,同性性取向者(同性恋)和性取向为异性或双性或未确定者(非同性恋)艾滋病病毒(human immunodeficiency virus,HIV)和梅毒感染状况,探讨MSM同性恋和非同性恋者感染HIV和梅毒的相关因素。方法采用横断面调查的方法,以北京、哈尔滨、郑州和成都市为调查现场,通过"滚雪球"的方法在MSM人群中招募调查对象,调查内容包括社会人口学特征、性伴和性行为、HIV和梅毒抗体血清学检测。运用Epi Data 3.0软件建立数据库,使用SPSS 13.0软件进行统计分析。结果共1 693名符合条件的MSM,其中同性恋和非同性恋者所占的比例分别为67.5%和32.5%。同性恋和非同性恋者HIV感染检出率分别为6.8%、7.1%,梅毒检出率分别为11.6%、13.3%。在同性恋者中,年龄在18～24岁及无收入者所占的比例为41.6%和22.1%,均高于非同性恋者(均有P<0.001)。同性恋者感染HIV和梅毒的多因素分析结果显示,居住在成都市、在浴池等洗浴场所寻找性伴、男男肛交性角色仅做被插入方者或既做插入方又做被插入方者及感染梅毒者感染HIV的危险性增加,居住在哈尔滨市、在公园公厕寻找性伴、男男肛交性角色为仅做被插入方者或既做插入方又做被插入方者、男男肛交时未坚持使用安全套、HIV感染者和近6个月性伴数≥6个者感染梅毒的危险性增加;非同性恋者感染HIV和梅毒的多因素分析结果显示,居住在成都及感染梅毒者感染HIV的危险性增加,通过互联网寻找性伴者感染HIV的危险性降低,男男肛交时未坚持使用安全套及HIV感染者感染梅毒的危险性增加。结论 MSM人群同性恋和非同性恋亚群中HIV和梅毒均呈现高流行状态,两者的社会人口学构成及其HIV及梅毒感染的相关因素不尽相同,提示,在MSM人群中控制HIV和梅毒流行需要区别不同亚群的特点开展针对性干预策略和措
Objective To understand the status of HIV and syphilis infection between gay and non-gay among men who have sex with men （ MSM ） in four cities of China and to determine the factors associated with HIV and syphilis infection among gay and non-gay, respectively.

The HIV prevalence of gay and non-gay were 6.8% and 7.1%, and the prevalence of syphilis infection were 11.6% and 13.3% accordingly. Among gay, the participants at age of 18-24 years and without income accounted for 41.6% and 22.1% respectively, which were higher than that of non-gay （both P〈0.001 ）. The results of multiple Logistic regression analysis showed that risk factors of HIV infection among gay included living in Chengdu, searching for sexual partners in baths or sauna, whose anal sex position was only receptive or both insertive and receptive, and syphilis infection.
