摘　　要：目的了解兰州市男男性行为人群(MSM)艾滋病(AIDS)流行状况和影响因素,分析MSM艾滋病流行趋势,为艾滋病疫情估计和预测提供相关信息,为制定艾滋病防治策略和干预措施提供科学依据。方法采用MSM志愿者"滚雪球"的方法,对出入酒吧和洗浴场所的MSM进行问卷调查及血清学检测。结果 2006-2010年连续5年共调查889人。其中未婚者574人,占64.57%;已婚者282人,占31.72%;离异或丧偶者33人,占3.71%。共发现艾滋病病毒(HIV)阳性者53例,阳性率为5.96%(53/889);梅毒阳性者121例,阳性率为13.61%(121/889);丙型肝炎(丙肝)阳性者12人,阳性率1.85%(12/650)。2006-2010年,各年MSM人群的HIV阳性率分别为0.92%(1/109)、2.31%(3/130)、7.00%(14/200)、5.50%(11/200)、9.60%(24/250),经χ2检验,差异有统计学意义(P<0.05),HIV感染有上升趋势;各年梅毒阳性感染率分别为0.92%(1/109)、4.62%(6/130)、23.00%(46/200)、18.50%(37/200)、12.40%(31/250),经χ2检验,差异有统计学意义(P<0.01);近3年丙肝阳性率分别为1.50%(3/200)、1.50%(3/200)、2.40%(6/250),经χ2检验,差异无统计学意义(P>0.05)。结论兰州市MSM人群HIV感染率达到了较高水平,安全套使用率低,多性伴、梅毒感染率高等都是促使HIV快速传播的影响因素。Objective To investigate the epidemic status of HIV/AIDS among men who have sex with men（MSM） and its influencing factors,analyze the HIV/AIDS epidemic-related information,and to estimate and predict the AIDS epidemic trends in MSM so as to provide scientific basis for furthure prevention and control strategies and interventions for AIDS.Method From 2006 to 2010,a questionnaire survey and HIV antibody tests were conducted among MSM volunteers entering bars and bathing salons by using snowballing sampling.Results Among the 889 MSM surveyed in the successive years,64.57%（574） were unmarried,31.72%（282） were married and 3.71%（33） were divorced and widowed;53 persons were diagnosed as HIV positive with a positive rate of 5.96%,Furthermore,121 MSM were diagnosed as syphilis positive with a positive rate of 3.61%;12 persons were diagnosed as HCV positive with a positive rate of 1.85%.The overall HIV infection rate from 2006 to 2010 was 0.92%（1/109）,2.31%（3/130）,7.00%（14/200）,5.50%（11/200） and 9.60%（24/250）,respectively.Statistical significance was found（χ2=14.406,P0.05） and the HIV infection tended to rise.The syphilis infection rate from 2006 to 2010 was 0.92%（1/109）,4.62%（6/130）,23.00%（46/200）,18.50%（37/200） and 12.40%（31/250）,respectively,Statistical significance was detected（χ2=43.255,P0.01）,and the syphilis infection rate has changed significantly.The HCV infection rate from 2008 to 2010 was 1.50%（3/200）,1.50%（3/200）and 2.40%（6/250）,respectively and no statistical significance was detected（χ2=0.688,P0.05）.Conclusion The prevalence of HIV has reached a high level among MSM in Lanzhou city.Low rate of condom use,multiple sex partners,and high syphilis infection rate are the risk factors to promote rapid spread of HIV among MSM.
