Characteristics of sexual partner network and high-risk sex behaviors among men who have sex with men

【目的】了解男男性行为人群的性伴网络、高危行为发生情况及相关因素,为开展男男性行为人群综合干预提供依据。【方法】通过咨询检测门诊、同伴推动、网络动员、外展干预等方式招募调查对象,开展面对面问卷调查,用SPSS 16. 0软件进行描述性、卡方检验、logistic回归等分析。【结果】共招募调查对象334名。过去6个月中,有女性伴、固定男性伴、多次男性伴、偶遇男性伴和商业男性伴的比例分别为37. 13%、43. 11%、52. 69%、56. 29%和4. 19%。多因素分析显示,在婚、文化程度低、非上海户籍、非同性恋者拥有女性伴的比例高;高收入、同性恋者拥有固定男性伴的比例高;在婚、非上海户籍者拥有多次男性伴和偶遇男性伴的比例高。过去6个月中,与女性伴、固定男性伴、多次男性伴、偶遇男性伴发生高危性行为的比例分别为75. 81%、65. 97%、59. 66%和48. 40%,年龄越大,与多次男性伴发生高危性行为的比例越高。【结论】男男性行为人群性伴网络复杂,性伴类型多;与性伴发生高危性行为普遍存在,年龄是多性伴高危性行为的相关因素。
