Men who have sex with men (MSM) have a relatively high prevalence of sexually transmitted infections (STIs). This study examines the association of self-reported STIs and use of mobile phones and/or computer-based Internet to meet sexual partners among black and Hispanic/Latino MSM in the United States.
Black and Hispanic/Latino MSM (N = 853) were recruited from 3 US cities (Chicago, IL; Kansas City, MO; and Fort Lauderdale, FL) via online and community outreach. Men completed a computer-assisted, self-interview assessment on demographics, use of mobile phones and computer-based Internet for sex-seeking, sexual risk behavior, and self-reported bacterial STIs in the past year. Multivariable logistic regression was used to model independent associations of STIs and use of these technologies to meet sexual partners.
Twenty-three percent of the sample reported having an STI in the past year; 29% reported using a mobile phone and 28% a computer-based Internet mostly for sex-seeking; and 22% reported using both. Number of male sexual partners (past year) was associated with any STI (adjusted odds ratio, 1.03; 95% confidence interval, 1.01-1.06). Adjusting for human immunodeficiency virus status, number of male sexual partners (past year), and demographic variables, men who reported use of both mobile phones and computer-based Internet for sex-seeking had increased odds of reporting an STI (adjusted odds ratio, 2.59; 95% confidence interval, 1.75-3.83), as well as with separate reports of chlamydia, gonorrhea, and syphilis (P's < 0.05).
Enhanced community education regarding STI prevention, testing, and treatment options are necessary among this subpopulation of MSM who may benefit from messaging via Internet and mobile phone application sites.
男男性行为者（MSM）的性传播感染（STIs）患病率相对较高。本研究调查了美国黑人和西班牙裔/拉丁裔男男性行为者中自我报告的性传播感染与使用手机和/或基于计算机的互联网寻找性伴侣之间的关联。
通过在线和社区宣传从美国3个城市（伊利诺伊州芝加哥市、密苏里州堪萨斯城市和佛罗里达州劳德代尔堡市）招募了黑人和西班牙裔/拉丁裔男男性行为者（N = 853）。参与者完成了一项计算机辅助的自我访谈评估，内容包括人口统计学、使用手机和基于计算机的互联网寻找性伴侣、性风险行为以及过去一年中自我报告的细菌性性传播感染情况。采用多变量逻辑回归模型来分析性传播感染与使用这些技术寻找性伴侣之间的独立关联。
23%的样本报告在过去一年中患有性传播感染；29%报告使用手机，28%报告主要使用基于计算机的互联网寻找性伴侣；22%报告两者都使用。男性性伴侣数量（过去一年）与任何性传播感染相关（调整后的优势比为1.03；95%置信区间为1.01 - 1.06）。在调整了人类免疫缺陷病毒感染状况、男性性伴侣数量（过去一年）和人口统计学变量后，报告同时使用手机和基于计算机的互联网寻找性伴侣的男性报告性传播感染的几率增加（调整后的优势比为2.59；95%置信区间为1.75 - 3.83），单独报告衣原体、淋病和梅毒感染的情况也是如此（P值<0.05）。
对于这一男男性行为者亚群体，有必要加强关于性传播感染预防、检测和治疗选择的社区教育，他们可能会从通过互联网和手机应用程序网站发送的信息中受益。
