男男性行为者（MSM）感染人类免疫缺陷病毒1型（HIV-1）的风险很高，因为他们有多个性伴侣和无保护的肛交（UAI）等危险行为。在全球范围内，约有5%至10%的艾滋病毒-1新感染是通过男性同性恋行为传播的。(1)中国艾滋病疫情呈现由高危人群向普通人群扩散的趋势。男男性接触者的高危行为和相对较大的人群规模表明，他们有可能显著促进中国HIV-1流行病的增加。2中国最新的HIV-1估计表明，约70万感染者中有11%是通过同性恋传播感染的，比2005年的7.3%有所增加。（3,4）越来越多的男同性恋者使用互联网进行互动。（5.6）对中国6个城市的传统场所进行的一项研究调查数据显示，互联网是一种常见的性交易方式。7一项调查聊天室和电子邮件互动的研究显示，近70%的男同性恋者是通过互联网认识的，约67%的男同性恋者在不带避孕套的情况下进行肛交。伦敦的一项研究揭示了在线和离线招募的男同性恋者在某些特征上的差异，包括年龄、教育程度、特定时期内男性伴侣的数量、危险的性行为和艾滋病毒状况。（9,10）这种差异对制定有效和适当的干预措施很重要。本研究的目的是检验通过传统渠道和互联网招募的男同性恋者之间可能存在的差异。
Men who have sex with men (MSM) are at high risk for infection with human immunodeficiency virus type 1 (HIV-1) because of risk behaviors such as multiple partners and unprotected anal intercourse (UAI). Approximately 5% to 10% of all new HIV-1 infections are transmitted by male homosexual behaviors globally.(1) The HIV epidemic in China is Currently spreading from high risk groups to the general population. The high risk behaviors in MSM and the relatively large size of this Population suggest that they have the potential to significantly contribute to an increasing HIV-1 epidemic in China. 2 The latest HIV-1 estimates from China indicate that 11% of the approximately 700000 infected individuals were infected through homosexual transmission, which has increased frorn 7.3% in 2005.(3,4)Increasing numbers of MSM have used the Internet to solicit interactions.(5.6) Data From a Study survey of conventional venues in 6 Chinese cities revealed that a commonly available method of soliciting sex was through the Internet. 7 A study which Surveyed chat rooms and e-mail interactions revealed that nearly 70% of MSM met one another through the Internet, and approximately 67% practiced anal sex without a condom. 8 A London Study revealed differences between MSM recruited online and offline in certain characteristics including age, education, number of male partner(s) in given period, risky sexual behaviors, and HIV status.(9,10) Such differences were important in the development of effective and appropriate interventions.The objective of this study is to examine the differences likely to exist between MSM recruited through conventional venues and the Internet.
