【摘要】 目的了解黑龙江省四市男男性行为人群(MSM)HIV/梅毒/HCV感染状况及其影响因素,评价行为干预效果,为制定针对性干预策略提供建议。方法应用同伴推动抽样法和分类滚雪球法招募MSM一对一问卷调查,采血检测HIV、梅毒、HCV抗体。梅毒患病的多因素分析采用逐步向前二项Logistic回归分析(α入=0.10,α出=0.15)。结果调查1 353人,1 348人接受检测,HIV感染率2.3%(0.3%~4.5%),梅毒现患率14.8%(5.3%~24.5%),HCV感染率0.5%(0~0.9%)。年龄≥25岁、少数民族、多男性伴行为是梅毒患病的危险因素。结论四市MSM人群的行为干预工作未对艾滋病性病控制产生决定影响,较低的性行为安全水平还不足以影响艾滋病性病的传播,多男性伴行为是目前影响艾滋病性病传播的重要行为危险因素,干预工作的有效性和针对性亟待加强。更多还原

【Abstract】 Objective To investigate the HIV,syphilis,HCV infection status and its influence factors in MSM in four cities of Heilongjiang Province,and to evaluate the intervention effects so as to provide suggestion for targeted policy establishment.Methods A face-to-face structured questionnaire interview was conducted among MSM recruited by using respondent driven sampling(RDS)and snowball sampling.Tests for HIV,syphilis and HCV antibodies in serum were conducted.Multivariate-factor forward stepwise logistic regression analysis was used for syphilis infection(αin=0.10,αout=0.15).Results A total of 1 348 MSM were tested,of which HIV,syphilis,HCV infection rates were 2.3%(0.3%-4.5%),14.8%(5.3%-24.5%),0.5%(0-0.9%),respectively.The risk factors of syphilis infection included 25 years of age and above,minority nationality and multiple male sex partners.Conclusion The behavior intervention services have not had essential impact on HIV/AIDS and STDs control.The low safe sex behavior has not obviously impacted HIV/AIDS and STDs transmission and multiple male sex partner is the most important risk factor for HIV/STD transmission.Effective and targeted intervention should be strengthened.更多还原
