江苏省男男性行为人群HIV和梅毒感染状况及影响因素研究

目的 了解江苏省男男性行为人群（men who have sex with men，MSM）人类免疫缺陷病毒（human immunodeficiency virus，HIV）和梅毒感染状况及影响因素。方法 2015年在江苏省8个地级市招募MSM，并进行问卷调查及实验室检测，采用多因素Logistic回归模型分析HIV和梅毒感染的影响因素。结果 2 451名MSM的HIV感染率为10.3%，梅毒现症感染率为8.3%。多因素分析结果显示:40岁及以上、网络招募、最近6个月发生无保护性肛交（unprotected anal intercourse，UAI）、最近一年未接受过HIV检测及正在感染梅毒是MSM人群感染HIV的主要危险因素（均有P<0.05）；25岁及以上、初中及以下文化程度、场所招募及最近6个月发生UAI是MSM人群感染梅毒的主要危险因素（均有P<0.05）。结论 江苏省MSM人群HIV感染持续呈高水平状况，梅毒现症感染得到控制。促进安全套使用和HIV/梅毒检测应持续成为MSM人群性病艾滋病防治的重要工作。

Prevalence of HIV and syphilis infection and their associated factors among men who have sex with men in Jiangsu Province

Objective To understand the prevalence of human immunodeficiency virus (HIV) and syphilis infection and their associated factors among men who have sex with men (MSM) in Jiangsu Province. Methods MSM from eight cities in Jiangsu Province were recruited for questionnaire interview and laboratory test in 2015. Multivariate Logistic regression model was used to analyze associated factors of HIV and syphilis infection. Results The prevalence of HIV and syphilis were 10.3% and 8.3% among 2 451 MSM, respectively. MSM who were older than 40 years were recruited via internet, engaged in unprotected anal intercourse (UAI) in the past 6 months, did not have an HIV test in the past year and were currently infected with syphilis were susceptible to HIV infection (all P<0.05). MSM who were older than 24 years, had an education level of junior high school or less were recruited in venues and engaged in UAI in the past 6 months were susceptible to syphilis infection(all P<0.05). Conclusions Continuous high HIV prevalence and controlled syphilis epidemic were shown among MSM in Jiangsu Province. Condom usage and HIV/syphilis testing promotion should be prioritized when attempting to reduce HIV/syphilis transmission among MSM in Jiangsu Province.
