2010－2013年中国男男性行为人群艾滋病/梅毒感染状况、性行为特征及艾滋病知识知晓情况的Meta分析

目的 通过2010－2013年针对MSM人群的调查进行Meta分析,了解近年来中国MSM人群的性行为特征、艾滋病知识知晓率情况、HIV/梅毒的感染状况及其随时间和地区的分布。方法 检索中国期刊全文数据库(CNKI)、万方数据库、PubMed数据库上已发表的2010－2013年针对中国MSM人群HIV、梅毒感染状况的文献,采用Stata 12.0软件对入选文献进行Meta分析。结果 共有66篇文献纳入,2010－2013年中国MSM人群中HIV合并感染率为7.7%(95%CI:7.2%～8.3%),呈逐年上升趋势,其中西南地区合并HIV感染率最高(12.0%);合并梅毒感染率为10.9%(95%CI:9.8%～12.1%),华南地区合并梅毒感染率最高(14.4%);性行为特征呈现近6个月肛交发生率偏高(84.2%),肛交坚持使用安全套率较低(44.8%)的特点,但该人群有较高的艾滋病知识知晓率(88.4%)。结论 2010－2013年中国MSM人群HIV、梅毒感染疫情呈高流行态势,面对该人群“高艾滋病知识知晓率,高无保护性性行为”这一普遍现象,探求有效促进MSM人群安全套使用的综合干预策略,减少“知行分离”的发生尤为重要。

Objective To understand the time and area specific prevalence of HIV infection and syphilis, sexual behaviors and awareness of HIV/AIDS related knowledge among men who have sex with men (MSM) in the mainland of China during 2010-2013. Methods All the published academic papers on the prevalence of HIV infection and syphilis among MSM in the mainland of China from 2010 to 2013 were collected from CNKI, Wanfang and PubMed databases. Meta-analysis was performed by using software Stata 12.0. Results Sixty six papers were selected. From 2010 to 2013 the pooled prevalence of HIV infection were 7.7% among the MSM (95%CI:7.2%-8.3%) and increased year by year, but the pooled prevalence of HIV infection was highest in southwestern China (12.0%). The pooled prevalence of syphilis were 10.9% among the MSM (95%CI:9.8%-12.1%), and the pooled prevalence of syphilis was highest in southern China (14.4%). The incidence of anal sex was high (84.2%) in the past 6 months, but the consistent condom use rate was low (44.8%). The AIDS related knowledge awareness was high in the MSM (88.4%). Conclusion The prevalence of HIV infection and syphilis were high among the MSM in the mainland of China during 2010-2013. It is necessary to explore the comprehensive intervention measures to promote condom use among MSM although they have high awareness of AIDS related knowledge.
