摘　　要：目的比较江苏省苏州、扬州2市男男性行为者(MSM)艾滋病病毒和性传播疾病(HIV/STD)感染状况及行为特征,为实施干预提供依据。方法于2009年4—7月采用横断面调查方法,在苏州市和扬州市分别调查MSM 305和300人,采集血样检测HIV、梅毒螺旋体抗体等,并对结果进行对比分析。结果苏州市MSM艾滋病知识知晓率为91.5%(279/305),扬州市为89.0%(267/300),差异无统计学意义;苏州市MSM首次插入性行为发生年龄为(21.35±3.98)岁,扬州市为(21.97±7.22)岁,差异无统计学意义;苏州市MSM首次同性性行为年龄为(22.78±6.03)岁,小于扬州市的(27.27±10.08)岁(t=6.66,P<0.001);MSM发生异性性行为时安全套坚持使用率苏州市为22.6%(19/84),扬州市为19.7%(35/178),最近1次异性性行为安全套使用率苏州市为39.3%(33/84),扬州市为28.7%(51/178),差异均无统计学意义;苏州市MSM同性多性伴和无保护肛交等高危行为暴露比例均高于扬州市(P<0.05);苏州和扬州市MSM的HIV感染率分别为9.2%(28/305)和10.0%(30/300),差异无统计学意义,梅毒感染率分别为19.7%(60/305)和31.3%(94/300),苏州市低于扬州市(χ2=10.84,P=0.001)。结论苏州市MSM艾滋病相关高危行为暴露率较高,而扬州市MSM梅毒等性传播疾病流行则更为较重,应根据其特征制订相关干预措施。Objective To compare the prevalence of human immunodeficiency virus/sexually transmitted disease（HIV/STD） as well as its related behaviors among men who have sex with men（MSM） between Suzhou and Yangzhou city and to provide evidence for specific intervention on the diseases.Methods Between April and July 2009,305 MSM in Suzhou city and 300 MSM in Nanjing city were investigated with a cross-sectional questionnaire survey.Blood samples were collected for HIV/STD test.Results There were significant differences in age,marital status,census register,education,occupation,monthly income,knowledge about AIDS among the MSM between the two cities.MSM in Suzhou were more likely to have multiple homosexual partners and have unprotected anal sex with men than MSM in Yangzhou.The prevalence rate of HIV infection in Suzhou was 9.2%（28/305） and the rate was 10.0%（30/300） in Yangzhou,without significant difference between the two cities.The prevalence rate of syphilis was 19.7%（60/305） in Suzhou,which was significantly lower than 31.3%（94/300） in Yangzhou.Conclusion There were some differences in demographics and risk behaviors between MSM in the two cities.Related measures of HIV/AIDS prevention and control should be adjusted to local conditions.
