The American Men's Internet Survey (AMIS) is an annual Web-based behavioral survey of men who have sex with men (MSM) living in the United States. This Rapid Surveillance Report describes the third cycle of data collection (September 2015 through April 2016; AMIS-2015). The key indicators are the same as previously reported for AMIS (December 2013-May 2014, AMIS-2013; November 2014-April 2015, AMIS-2014). The AMIS survey methodology has not substantively changed since AMIS-2014. MSM were recruited from a variety of websites using banner advertisements and email blasts. Additionally, participants from AMIS-2014 who agreed to be recontacted for future research were emailed a link to the AMIS-2015 survey. Men were eligible to participate if they were age 15 years and older, resided in the United States, provided a valid US ZIP code, and reported ever having sex with a man. We examined demographic and recruitment characteristics using multivariable regression modeling (P<.05) stratified by participants' self-reported human immunodeficiency virus (HIV) status. The AMIS-2015 round of data collection resulted in 10,217 completed surveys from MSM representing every US state and Puerto Rico. Participants were mainly non-Hispanic white, older than 40 years, living in the US South, living in urban areas, and recruited from general social networking websites. Self-reported HIV prevalence was 9.35% (955/10,217). 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 (75.50%, 721/955 vs 63.09%, 5843/9262, P<.001) and more likely to have had anal sex without a condom with a serodiscordant or unknown status partner (34.45%, 329/955 vs 17.07%, 1581/9262, P<.001). The reported use of marijuana and other illicit substances in the past 12 months was higher among HIV-positive participants than HIV-negative/unknown status participants (marijuana use: 24.61%, 235/955 vs 22.96%, 2127/9262; other illicit substance use: 28.59%, 273/955 vs 17.51%, 1622/9262, respectively; both P<.001). Most HIV-negative/unknown status participants (79.11%, 7327/9262) reported ever having a previous HIV test, and 55.69% (5158/9262) reported HIV testing in the past 12 months. HIV-positive participants were more likely to report sexually transmitted infection (STI) testing and diagnosis compared to HIV-negative/unknown status participants (STI testing: 71.73%, 685/955 vs 38.52%, 3568/9262; STI diagnosis: 25.65%, 245/955 vs 8.12%, 752/9262, respectively; both P<.001).
美国男性互联网调查（AMIS）是一项针对居住在美国的男男性行为者（MSM）的年度网络行为调查。本快速监测报告描述了第三个数据收集周期（2015年9月至2016年4月；AMIS - 2015）。关键指标与之前AMIS报告的相同（2013年12月 - 2014年5月，AMIS - 2013；2014年11月 - 2015年4月，AMIS - 2014）。自AMIS - 2014以来，AMIS调查方法没有实质性变化。通过横幅广告和电子邮件群发从各种网站招募男男性行为者。此外，同意在未来研究中再次被联系的AMIS - 2014参与者通过电子邮件收到了AMIS - 2015调查的链接。年龄在15岁及以上、居住在美国、提供有效的美国邮政编码且报告曾与男性发生过性行为的男性有资格参与。我们使用多变量回归模型（P <.05）按参与者自我报告的人类免疫缺陷病毒（HIV）状态分层，研究了人口统计学和招募特征。AMIS - 2015的数据收集轮次共收到来自代表美国每个州和波多黎各的男男性行为者的10217份完整调查问卷。参与者主要是非西班牙裔白人，年龄超过40岁，居住在美国南部，居住在城市地区，且是从一般社交网站招募的。自我报告的HIV流行率为9.35%（955/10217）。与HIV阴性/状态未知的参与者相比，HIV阳性参与者在过去12个月中更有可能与任何男性伴侣无保护肛交（75.50%，721/955对63.09%，5843/9262，P <.001），并且更有可能与血清学不一致或状态未知的伴侣无保护肛交（34.45%，329/955对17.07%，1581/9262，P <.001）。在过去12个月中，报告使用大麻和其他非法物质的HIV阳性参与者高于HIV阴性/状态未知的参与者（大麻使用：24.61%，235/955对22.96%，2127/9262；其他非法物质使用：分别为28.59%，273/955对17.51%，1622/9262；两者P <.001）。大多数HIV阴性/状态未知的参与者（79.11%，7327/9262）报告曾进行过HIV检测，55.69%（5158/9262）报告在过去12个月中进行过HIV检测。与HIV阴性/状态未知的参与者相比，HIV阳性参与者更有可能报告性传播感染（STI）检测和诊断（STI检测：71.73%，685/955对38.52%，3568/9262；STI诊断：分别为25.65%，245/955对8.12%，752/9262；两者P <.001）。
