This population of young people are also disproportionately burdened by negative outcomes associated with sex and substance use behaviors, even when their behavior is less risky. Given the increased likelihood of negative outcomes, we investigated how youth talk about these behaviors in their online social networks. This mixed methods study integrates a behavioral survey with a machine learning-supported, qualitative content analysis of one year of Facebook and Twitter posts from 50 participants, with feedback from a youth advisory board. Findings suggest that participants who drank were more likely to post about alcohol. Women posted more about STIs, HIV and pregnancy. Posts around sexual behavior often discussed trust in sexual partnerships and gendered views of sex. Alcohol and marijuana were used to relieve stress, to handle personal grief and community violence, and as a coping mechanism for general distress. Understanding how youth think about sexual risk and substance use can inform the design of more effective prevention efforts.12 pagesengAttribution-NonCommercial-NoDerivatives 4.0 InternationalCritical and Ethical Studies of Digital and Social MediaDigital and Social Mediasexual health, social media, substance use, youthConference Paper10.24251/HICSS.2019.261
