男男性行为者（MSM）受到人类免疫缺陷病毒（HIV）的影响不成比例，有证据表明这一人群正在参与越来越危险的性行为。这些变化是在新的在线社交互动模式的背景下发生的-许多MSM现在报告说，他们第一次在互联网上遇到他们的性伴侣。要更好地监测男男性行为者的关键行为指标，就需要使用利用这些新的互动模式的监测战略。因此，我们开发了一个年度横断面行为调查的男男性接触者在美国，美国男性互联网调查（AMIS）。本文的目的是提供AMIS方法的描述。此外，我们报告了第一轮数据收集（2013年12月至2014年5月; AMIS-2013），这些数据与用于国家艾滋病毒行为监测的关键指标相同。AMIS-2013使用横幅广告或电子邮件爆炸从各种网站招募MSM。目前居住在美国的成年男性有资格参加，如果他们曾经与一名男子发生过性关系。我们使用多变量回归模型（P<0.05）分层的参与者的自我报告的艾滋病毒状态检查人口统计学和招募特征。在AMIS-2013轮中，79，635人登陆研究页面，14，899人符合条件，代表美国各州的MSM完成了10，377项调查。参与者主要是白色人，年龄在40岁或以上，居住在美国南部，居住在城市地区，从一个普通的社交网站招募。自报HIV感染率为10.73%（n=1113）。与HIV阴性/未知状态的参与者相比，HIV阳性参与者在过去12个月内更有可能在没有安全套的情况下与任何男性伴侣进行肛交（分别为72.24%和61.24%; P<.001），更有可能在没有安全套的情况下与其最后一位HIV状态不一致/未知的男性性伴侣进行肛交（分别为42.95%和13.62%; P<.001）。在过去的12个月中，HIV阳性参与者比HIV阴性/未知状态参与者更有可能报告非法药物使用（分别为39.17%和26.85%; P<.001）。绝大多数HIV阴性/未知状态的参与者（84.05%）以前接受过HIV检测，但不到一半（44.20%）在过去12个月内接受过检测。18-24岁的参与者比40岁或40岁以上的参与者更有可能在没有安全套的情况下与不一致/未知的艾滋病毒状态的伴侣进行肛交，更有可能报告使用药物，并且不太可能接受艾滋病毒检测。与一般社交网络相比，来自地理空间社交网站的人更有可能报告所有风险行为，但更有可能接受艾滋病毒检测。第一轮的AMIS从10 000多名男男性行为者互联网用户中产生了有用的行为测量结果。初步调查结果确定了一些亚群的男男性接触者的互联网用户是在潜在的艾滋病毒感染/传播的风险较高。AMIS将提供一个持续的数据来源，用于研究男男性行为者的性风险行为趋势。这将有助于规划和监测方案的影响，以改善这一人口的健康。
Men who have sex with men (MSM) are disproportionately affected by human immunodeficiency virus (HIV) and there is evidence that this population is participating in increasingly risky sexual behavior. These changes are occurring in the context of new modes of online social interaction—many MSM now report first meeting their sex partners on the Internet. Better monitoring of key behavioral indicators among MSM requires the use of surveillance strategies that capitalize on these new modes of interaction. Therefore, we developed an annual cross-sectional behavioral survey of MSM in the United States, the American Men's Internet Survey (AMIS). The purpose of this paper was to provide a description of AMIS methods. In addition we report on the first cycle of data collection (December 2013 through May 2014; AMIS-2013) on the same key indicators used for national HIV behavioral surveillance. AMIS-2013 recruited MSM from a variety of websites using banner advertisements or email blasts. Adult men currently residing in the United States were eligible to participate if they had ever had sex with a man. We examined demographic and recruitment characteristics using multivariable regression modeling (P<.05) stratified by the participants' self-reported HIV status. In the AMIS-2013 round, 79,635 persons landed on the study page and 14,899 were eligible, resulting in 10,377 completed surveys from MSM representing every US state. Participants were mainly white, 40 years or older, living in the US South, living in urban areas, and recruited from a general social networking website. Self-reported HIV prevalence was 10.73% (n=1113). Compared to HIV-negative/unknown status participants, HIV-positive participants were more likely to have had anal sex without a condom with any male partner in the past 12 months (72.24% versus 61.24%, respectively; P<.001) and more likely to have had anal sex without a condom with their last male sex partner who was discordant/unknown HIV status (42.95% versus 13.62%, respectively; P<.001). Illicit substance use in the past 12 months was more likely to be reported by HIV-positive participants than HIV-negative/unknown status participants (39.17% versus 26.85%, respectively; P<.001). The vast majority of HIV-negative/unknown status participants (84.05%) had been previously HIV tested, but less than half (44.20%) had been tested in the past 12 months. Participants 18-24 years of age were more likely than those 40 years or older to have had anal sex without a condom with a discordant/unknown HIV status partner, were more likely to report substance use, and were less likely to have been HIV tested. Compared to general social networking, those from a geospatial social networking website were more likely to have reported all risk behaviors but were more likely to have been HIV tested. The first round of AMIS generated useful behavioral measures from more than 10,000 MSM Internet users. Preliminary findings identified some subgroups of MSM Internet users that are at potentially higher risk of HIV acquisition/transmission. AMIS will provide an ongoing data source for examining trends in sexual risk behavior of MSM. This will help to plan and monitor the impact of programs to improve this population's health.
