中国西部地区男男性行为人群艾滋病相关知识及行为调查分析

Knowledge and behaviors related to HIV/AIDS among men who have sex with men in western China

目的:中国西部地区男男性行为人群(Men who have sex with men,MSM)艾滋病病毒(Human immunodeficiency virus,HIV)感染率较高,对该地区MSM的艾滋病(Acquired immunodeficiency syndrome,AIDS)相关知识及行为进行调查,为制定该人群艾滋病防治策略及行为干预措施提供较为切实的依据和参考。方法:研究设计为横断面调查,于2009年7月至2010年4月对我国西部的重庆、四川、广西三省市1 407名MSM进行问卷调查。结果:MSM的年龄中位数是26岁,同性恋者占69.26%,双性恋者占21.40%。艾滋病相关知识知晓率为88.37%。最近6个月,61.22%的MSM有2个及以上同性性伴,7.42%的有同性商业性行为,12.48%的有异性性行为。近6个月内男男肛交性行为时每次都坚持使用安全套的占46.40%。最近6个月与不同对象发生性行为时的安全套使用有差别(P<0.05)。不同地区、是否多性伴和是否有同性商业行为与安全套的使用有关联。结论:中国西部地区MSM人群中普遍存在感染艾滋病的高危行为,且与其较高的艾滋病知识水平分离现象严重,这对该人群的行为干预提出了挑战,因此,探索控制MSM人群艾滋病传播的新干预模式具有重要意义。

Objective：To investigate AIDS related knowledge and behaviors among the MSM in western China,where the HIV infectious rate among this group is relatively high,so as to provide clues to design strategies on HIV/AIDS prevention and treatment as well as behavior interventions.Methods：From July 2009 to April 2010,cross-sectional surveys were conducted among 1407 MSM in Chongqing,Sichuan and Guangxi.Results：The age medium was 26 years old.The homosexual and the bisexual occupied 69.26% and 21.40% respectively.The knowledge awareness related to AIDS was 88.37%.In the past 6 months,61.22% of them had sex with 2 or more men;7.42% had homosexual commercial sex;12.48% had sex with women.And 46.40% of them insisted on condom utilization each time during anal sex.There was significant difference in condom utilization among them when having sex with different persons（P0.05）.There was a relationship between the condom utilization and the location and whether having more than one sex partners.Conclusion：Among MSM in western China,the HIV infectious high-risk behaviors are common,which is in contrast to their relatively high knowledge awareness rate.This should be viewed as a big challenge to the behavior interventions among MSM.As a result,it has great significance to explore a new intervention mode to control the HIV infection among MSM.
