Methods: Los-Angeles area homeless-youth ages 14-27 years (N=829) were recruited from two drop-in centers (Santa-Monica & Hollywood) as a part of a longitudinal study from 2011 to 2014. Participants were asked to complete a computerized self-administered questionnaire. Independent variables included questions related topics of discussion held on social media sites (class/school, media, drugs, sex/love, being homeless, school/work, family issues, and goals). Additionally, youth were asked about who they connected with on SNS’s (people from home, partners, streets peers, people met online, and caseworkers). Outcome -variables used to measure HIV behaviors, included condom-use, recent HIV-test, exchange-sex, exchange-sex with a partner met online, sex with someone met online, and concurrent-sex partners.
Results: Approximately, 80% of the participants reported using SNS’s; with almost 50% reporting using SNS’s daily. Multivariate logistic-regressions revealed that both who these youth communicated with on SNS’s as well as what they talked about were significantly associated with their sexual health behaviors. Specifically, talking about sex and/or love significantly predicted an increased likelihood of having a recent HIV-test (OR=2.40, CI 95%=1.35, 4.23). Talking about goals (OR=2.43, CI 95%=1.62, 3.61) and talking to someone from class (OR=1.72, CI 95%=1.15, 2.56) significantly predicted an increased likelihood of engaging in safe sex (with a condom). Furthermore, talking about sex and/or love was associated with an increased likelihood of having a recent HIV test (OR=2.40, CI 95%=1.35, 4.23).
Conclusion: Research using online social networks to bring about health behavior change is still in its early stages of development. Social media provide opportunities to reach traditionally underserved populations especially a hard to reach population such as homeless youth. Given the pervasiveness of social media use and the significant associations between social media communication and sexual health behaviors, an internet based peer led health intervention could be particularly effective for this population.
