Abstract

BACKGROUND

Internet-based platforms are increasingly prominent interfaces for social and sexual networking among men who have sex with men (MSM).

METHODS

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).

RESULTS

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).

CONCLUSIONS

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.

摘要

背景

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接口。

方法

2008年、2011年和2014年在美国20个城市通过场所抽样招募男男性行为者。我们使用泊松回归和广义估计方程来计算调整患病率比（APR），研究了2008年至2014年期间男男性行为者为结识男性而使用互联网的情况变化以及最近一个性伴是通过网络结识的情况变化。我们还利用2014年的数据研究了与互联网使用频率增加相关的因素。互联网使用情况分为从不使用、不频繁使用（<每周一次）和频繁使用（≥每周一次）。

结果

频繁使用互联网的比例从2008年的21%增至2014年的44%（APR = 1.39，95%置信区间：1.36至1.42），最近一个性伴是通过网络结识的比例从2008年的19%增至2014年的32%（APR = 1.30，95%置信区间：1.26至1.34）。从不使用互联网的人在过去12个月中的性伴数量较少（中位数为2，四分位间距：1 - 4），而不频繁使用者（4，2 - 7）和频繁使用者（5，3 - 12）的性伴数量较多。过去12个月内进行艾滋病毒检测的比例也随着互联网使用频率的增加而上升（分别为58%、68%和71%，P < 0.0001）。在艾滋病毒呈阳性的参与者中，艾滋病毒阳性知晓率随着互联网使用频率的增加而上升（71%、75%和79%，P < 0.005）。
