Online social networking usage is growing rapidly, especially among at-risk populations, such as men who have sex with men (MSM). However, little research has studied the relationship between online social networking usage and sexual risk behaviors among at-risk populations. One hundred and eighteen Facebook-registered MSM (60.1% Latino, 28% African American; 11.9% other) were recruited from online (social networking websites and banner advertisements) and offline (local clinics, restaurants and organizations) venues frequented by minority MSM. Inclusion criteria required participants to be men who were 18 years of age or older, had had sex with a man in the past 12 months, were living in Los Angeles, and had a Facebook account. Participants completed an online survey on their social media usage and sexual risk behaviors. Results from a multivariable regression suggest that number of sexual partners met from online social networking technologies is associated with increased: 1) likelihood of having exchanged sex for food, drugs, or a place to stay within the past 3 months; 2) number of new partners within the past 3 months; 3) number of male sex partners within the past 3 months; and 4) frequency of engaging in oral sex within the past 3 months, controlling for age, race, education, and total number of sexual partners. Understanding the relationship between social media sex-seeking and sexual risk behaviors among at-risk populations will help inform population-focused HIV prevention and treatment interventions.
在线社交网络的使用正在迅速增长，尤其是在高危人群中，例如男男性行为者（MSM）。然而，很少有研究探讨在线社交网络使用与高危人群中的性风险行为之间的关系。本研究从在线（社交网站和 banner 广告）和线下（当地诊所、餐馆和组织）场所招募了 118 名注册 Facebook 的 MSM（60.1%拉丁裔，28%非裔美国人；11.9%其他）。纳入标准要求参与者为 18 岁或以上的男性，过去 12 个月与男性发生过性行为，居住在洛杉矶，并且拥有 Facebook 账户。参与者完成了一项关于他们社交媒体使用和性风险行为的在线调查。多变量回归的结果表明，通过在线社交网络技术结识的性伴侣数量与以下方面的增加有关：1）过去 3 个月内因性而换取食物、毒品或住宿的可能性；2）过去 3 个月内的新伴侣数量；3）过去 3 个月内的男性性伴侣数量；以及 4）过去 3 个月内进行口交的频率，控制年龄、种族、教育程度和性伴侣总数。了解高危人群中社交媒体性寻求与性风险行为之间的关系，将有助于为以人群为重点的 HIV 预防和治疗干预措施提供信息。
