基于互联网的平台日益成为男男性行为者（MSM）社交和性网络的重要界面。2008年，2011年和2014年在美国20个城市通过基于场地的抽样招募了MSM。我们研究了2008年至2014年MSM中互联网使用（IU）以满足男性和满足最后一个在线伴侣的变化，使用泊松回归和广义估计方程计算调整后的患病率（APR）。我们还使用2014年的数据检查了与IU频率增加相关的因素。IU分为从不使用、不频繁使用（<每周一次）和频繁使用（≥每周一次）。频繁的IU从2008年的21%增加到2014年的44%（APR = 1.39，95%置信区间：1.36至1.42），并且在网上遇到最后一个伴侣从2008年的19%增加到2014年的32%（APR = 1.30，95%置信区间：1.26至1.34）。那些从不使用互联网的人的伴侣数量较少（过去12个月的中位数为2，四分位数范围：1-4），而不经常使用互联网的人（4，2-7）和经常使用互联网的人（5，3-12）。过去12个月内的HIV检测也随着IU的增加而增加（分别为58%，68%和71%，P < 0.0001）。在HIV阳性的参与者中，随着IU的增加，HIV阳性的知晓率也增加（71%，75%和79%，P < 0.005）。自2008年以来，在网上认识男人和认识最后一个伴侣的IU都有所增加。虽然使用互联网更频繁的男性在过去12个月内报告了更多的伴侣，但他们也更有可能在过去12个月内报告检测结果，并且更有可能意识到艾滋病毒呈阳性。
Internet-based platforms are increasingly prominent interfaces for social and sexual networking among men who have sex with men (MSM). MSM were recruited through venue-based sampling in 2008, 2011, and 2014 in 20 US cities. We examined changes in internet use (IU) to meet men and in meeting the last partner online among MSM from 2008 to 2014 using Poisson regression with generalized estimating equations to calculate adjusted prevalence ratios (APRs). We also examined factors associated with increased frequency of IU using data from 2014. IU was categorized as never, infrequent use (<once a week), and frequent use (≥once a week). Frequent IU increased from 21% in 2008 to 44% in 2014 (APR = 1.39, 95% confidence interval: 1.36 to 1.42), and having met the last partner online increased from 19% in 2008 to 32% in 2014 (APR = 1.30, 95% confidence interval: 1.26 to 1.34). Those who never used the internet had fewer partners (median of 2 in the past 12 months, interquartile range: 1–4) compared with infrequent (4, 2–7) and frequent users (5, 3–12). HIV testing in the past 12 months also increased with increasing IU (58%, 68%, and 71%, respectively, P < 0.0001). Among HIV-positive participants, the percent HIV-positive awareness increased as IU increased (71%, 75%, and 79%, P < 0.005). Both IU to meet men and meeting the last partner online increased since 2008. Although men who used the internet more frequently reported more partners in the past 12 months, they were also more likely to report testing in the past 12 months and were more likely to be HIV-positive aware.
