摘　　要：目的分析广州地区男男性接触者（men who have sex with men,MSM）人类免疫缺陷病毒抗体（抗-HIV）检测的相关情况,为开展艾滋病防治提供依据。方法检测2010年1月~2010年12月参加艾滋病自愿咨询检测的MSM的抗-HIV,并采用χ2检验分析其阳性率在性角色、文化程度、安全套使用、有无合并梅毒感染等方面的差异。结果共调查1526名MSM,确认HIV感染的人数87例、阳性率为5.70%。最近3个月内接受过HIV检查的有占27.36%（406/1484）,知道自己的HIV检查结果的占83.00%（337/406）,其阳性率达7.12%。MSM主动肛交者的抗-HIV阳性率为3.54%、被动肛交者为7.14%、两者兼有为6.70%,在性角色方面抗-HIV阳性率差异有统计学意义（χ2=6.450,P=0.040）。已婚的MSM其抗-HIV阳性率为9.45%,高于未婚的4.92%与离异的4.17%,其差异有统计学意义（χ2=7.184,P=0.028）。文化程度越低,抗-HIV阳性率越高,其差异有统计学意义（χ2=8.901,P=0.012）。如MSM合并梅毒则其抗-HIV阳性率为21.31%,无梅毒感染者其阳性率仅为5.06%,其差异有统计学意义（χ2=25.770,P〈0.001）。近3个月每次均使用安全套与最近1次使用安全套的MSM其抗-HIV阳性率虽然高于未使用者,但其差异无统计学意义（P〉0.05）。结论广州市MSM的抗-HIV阳性率较高,不安全性行为较高,特别是肛交时被动方MSM年纪轻,安全套使用率低,HIV感染率高,自我保护能力弱,成为MSM内HIV传播的高危人群。Objective To investigate the correlation between human immunodeficiency virus（HIV） and the sexual behaviors of men who have sex with men（MSM） in Guangzhou in 2010.Methods Anti-HIV antibody was detected in the volunteers undergoing HIV tests in the year 2010,and the differences in the sexual role,education,use of condom and complicated infection of syphilis were analyzed among these subjects.Results A total of 1526 MSM volunteered to participate in the investigation,among whom 87（5.70%） were confirmed to have HIV infection.The positivity rate of HIV infection was 3.54%,7.14% and 6.70% in subjects reporting active anal copulation,passive anal copulation,and both,respectively,showing a significant difference in respect of the sexual role（χ2=6.450,P=0.040）.The positivity rate also differed significantly among married,unmarried and divorced subjects（9.45%,4.92%,and 4.17%,respectively;χ2=7.184,P=0.028）.The positivity rate was 21.31% among those with syphilis,significantly higher than the rate in those without syphilis（5.06%,χ2=25.770,P0.001）.Use of condom was not associated with a significant reduction of HIV positivity rate（P0.05）.Conclusion The high anti-HIV positivity rate among MSM in Guangzhou indicates a high risk of unsafe sexual behaviors,especially anal copulations.The anal copulation receivers,often young and have a lower rate of condom use,constitute a high-risk group of HIV transmission.
