China has a significant population of MSM (men who have sex with men) and they have been becoming very much alive in many ways since 1990s due to recent social changes. Some surveys indicate that great many of MSM are engaged in high-risk behaviors. In addition, majority of MSM have also experienced sexual encounters with women sometimes in their lives, which possibly con- tribute to spread of HIV to women. Some reports documented that HIV is becoming rampant among MSM since more than 1% of them are now infected. Political, cultural and custom elements could hinder intervention activities against HIV spread among MSM. Fortunately, many cities in China have seen that MSM were in cooperation with responsible institutions carrying out certain intervention measures. The general situation is promising. The authors forecast that the fast HIV spread among MSM of China could possibly be halted within several years when the authorities become more sensible to this issue, health service institutions offer unswerving efforts toward the MSM community and those who involve in MSM undertakes necessary responsibilities.展开更多
目的：了解2010-2014年贵阳市MSM人群（men who have sex with men,MSM）HIV感染者性行为特征,为预防控制MSM人群HIV感染者二代传播提供依据。方法：本研究以2010-2014年的4-7月份在贵阳市MSM人群监测哨点检测出的HIV感染者为研究对象,...目的：了解2010-2014年贵阳市MSM人群（men who have sex with men,MSM）HIV感染者性行为特征,为预防控制MSM人群HIV感染者二代传播提供依据。方法：本研究以2010-2014年的4-7月份在贵阳市MSM人群监测哨点检测出的HIV感染者为研究对象,以一对一的方式进行问卷调查,并采集静脉血进行HIV和梅毒检测。结果：2010-2014年贵阳市MSM人群监测哨点共检测出的333名HIV感染者,年龄在18-24岁,所占的比例由2010年的55.4%下降到2014年的26.7%,在婚或同居所占的比例在5.0%-15.8%之间;文化程度大专及以上者由2010年的45.7%上升到2014年的70.0%。2010-2014年MSM人群感染者的梅毒感染检出率在6.7%-23.9%之间;最近6个月与同性发生肛交性行为所占的比例分别为79.7%-98.9%,与异性发生性行为所占的比例在7.8%-11.7%之间。73.6%-91.4%的MSM最近6个月同性肛交未坚持使用安全套;异性行为坚持使用安全套所占的比例仅为33.3%。结论：MSM人群HIV感染者年龄较小,主要处于性活跃阶段,梅毒的感染检出率较高,同性性行为及异性性行为时坚持使用安全套的比例均较低,将加速HIV和梅毒在MSM人群间及向异性人群传播。展开更多
