摘　　要：目的了解南京地区男-男性行为(MSM)人群的性行为特征、人类免疫缺陷病毒(HIV)感染状况及影响因素。方法利用同伴推动抽样法招募MSM人群,进行人口学、HIV知识和行为学调查,并检测血清HIV抗体及梅毒,分析结果。结果804例MSM人群年龄(30.57±10.53)岁。艾滋病知识知晓率82.84%。近6个月有42.16%(339/804)MSM与非固定性伴发生同性性行为,58.08%(467/804)MSM与1个以上性伴发生同性性行为;在与非固定性伴发生性行为时,56.33%(249/442)的MSM存在不安全性行为,HIV感染率为8.21%(66/804),梅毒感染率为22.89%(184/804)。多因素Logistic回归分析结果表明,近6个月同性性伴数多,非固定同性性伴肛交安全套使用水平低和现症梅毒感染是影响HIV感染的危险因素。结论南京地区MSM人群HIV知识知晓率高,但具有多性伴、安全套使用率低的特点,HIV感染率高且尚未得到有效控制,应根据地区特点开展针对性的有效干预措施。Objective To investigate sexual behavior characteristics of man who have sex with man （MSM）, infection status of HIV and related risk factors.
