To understand the change trend of the awareness rate of HIV/AIDS related knowledge, risk behaviors among men who have sex with men (MSM) in Yunnan and the factors influencing their condom use, and evaluate the effect of comprehensive intervention.
The data about the MSM's demographic information, HIV/AIDS related knowledge awareness, and sex behavior, condom use, drug use and intervention receiving were obtained from AIDS sentinel surveillance among MSM in Yunnan province during 2010-2013 to conduct change trend and influencing factor analysis.
A total of 9 073 MSM were surveyed. The awareness rate of the HIV/AIDS related knowledge, homosexual behavior and condom use rate increased year by year (P < 0.01). The condom use rate was lower in heterosexual behavior, and the drug use rate and sexually transmitted disease prevalence declined with year (P < 0.01). Multivariate logistic regression analysis indicated that cohabiting, low awareness of HIV/AIDS related knowledge, being from other provinces, local residence for <1 year, low education level, receiving no intervention, frequent anal sex and receiving no HIV/AIDS detection were the risk factors influencing persistent condom use among MSM.
The effect of HIV/AIDS comprehensive intervention was observed after 4 years implantation, but most of the index were at low level. More attention should be paid to the intervention among MSM with cohabiting habit, low education level, frequent anal sex, and heterosexual sex. It is necessary to expand intervention coverage, strengthen HIV test and promote condom use among MSM.
了解云南省男男性行为者（MSM）艾滋病相关知识知晓率、危险行为变化趋势及影响其使用避孕套的因素，并评价综合干预效果。
收集2010 - 2013年云南省MSM艾滋病哨点监测中有关MSM的人口学信息、艾滋病相关知识知晓情况、性行为、避孕套使用、吸毒及接受干预等数据，进行变化趋势及影响因素分析。
共调查9073名MSM。艾滋病相关知识知晓率、同性恋行为及避孕套使用率逐年上升（P < 0.01）。异性性行为中避孕套使用率较低，吸毒率及性传播疾病患病率逐年下降（P < 0.01）。多因素logistic回归分析显示，同居、艾滋病相关知识知晓率低、外省籍、在当地居住<1年、文化程度低、未接受干预、肛交频繁及未接受艾滋病检测是影响MSM持续使用避孕套的危险因素。
综合干预实施4年后观察到艾滋病综合干预效果，但多数指标处于较低水平。应更加关注有同居习惯、文化程度低、肛交频繁及有异性性行为的MSM的干预。有必要扩大干预覆盖面，加强艾滋病检测，促进MSM使用避孕套。
