目的了解男男性接触者（MSM）使用互联网的行为特征和对互联网行为干预的接受意向。方法于2009年12月至2010年1月通过某一同性恋网站招募MSM进行在线问卷调查.调查内容包括基本人口学资料、上网习惯、性取向、艾滋病高危行为、对艾滋病知识的需求和相关知识获得的途径、接受互联网干预的意向等，并采用x2检验分析不同人口特征及上网习惯的MSM对互联网干预的接受情况的差异。结果共有719名MSM完成问卷调查，719名MSM中以25～29岁组最多（占40．61％），以学历大专及以上（占78．30％）、未婚者（占87．34％）、同性恋（77．05％）为主。44．78％（322／719）的MSM在最近1个月和男性发生肛交性行为时坚持使用安全套，而最近1次和男性发生肛交性行为时安全套使用率为70．93％（510／719）；有29．62％（213／719）曾经和女性有过性行为，其中有57．75％（123／213）最近1次和女性发生性行为有使用安全套。75．24％（541／719）的MSM主要是在住所上网，79．28％（570／719）的对象每天都会上网。84．70％（609／719）的调查对象愿意通过网络途径获得预防艾滋病相关知识，愿意通过疾病预防控制中心（CDC）和医院等途径通过面对面获得预防艾滋病相关知识的分别为28．37％（204／719）和22．81％（164／719）。其中，年轻的、文化程度高的、性取向为同性恋的、主要上网地点为住所的MSM更愿意接受互联网干预（P〈0．01或0．05）。在接受互联网干预的平台选择上，84．14％（605／719）的MSM更愿意采用浏览网页等非互动方式获得互联网干预，远高于使用即时聊天工具（占29．35％，211／719）等网络互动形式。结论受调查的使用互联网的MSM人群更倾向于互联网干预的形式。互联网干预对控制艾滋病在MSM人群中的传播具有深刻的意义。

Objective To understand the internet use and on-line behavior characters of men who have sex with men （ MSM）, and explore the intention of internet-based intervention targeted to HIV high risk behaviors among them. Methods A cross-sectional study was carried out in MSM who were recruited in a gay website between December 2009 and January 2010. Data on demographic characteristics, surfing habits, HIV/AIDS related behavior, needs of information on H1V prevention and the way which they obtain the information were collected by online questionnaire survey. Chi-square test was used to determine the differences of the intention of internet-based intervention targeted to HIV high risk behaviors among MSM with different demographic characteristics and surfing habits. Results A total of 719 MSM finished the survey. Most of them were aged between 25 and 29 years （40.61%）, possessed high education level （78.30%）, unmarried （87.34%）, and identified themselves as homosexual （77.05%）. The percentage of using condom persistently when having the anal-intercourse with partners was 70.93% （510/719） dur- ing the last sex episode and 44.78% （322/719） in the last month. 29.62% of them （213/719） used tohave sexual relationship with female, 57. 75% （123/213） of which used condom at last sex episode. 75.24% of them （541/719） surfed the internet at home and 79.28% （570/719） surfed the internet everyday. 84.70% of the participants were willing to obtain information on HIV prevention through internet, while less than 30% were willing to obtain such information by face-to-face such as from CDC （28.37% , 204/719） or hospital （22.81% , 164/719）. The MSM who were young, possessed high education level, identified themselves as homosexual, or surfed the internet at home were more willing to accept the interact- based intervention （P 〈0.01 or 0.05 ）. 84.14% of them （605/719） were willing to attend the internet intervention by non-interactive way, much higher than those attend by online interactive forms （29.35% , 211/719）. Conclusion MSM recruited from internet were more likely to obtain information on HIV prevention through interact.
