This longitudinal study examines social media utilization among Latino youths, and differences by sex and acculturation. Objectives: The purpose of this study was to examine Latino adolescents’ social media utilization and behavior over a 16-month period, and to assess whether changes in use differed by sex and acculturation. Methods: This study included 555 Latino youths aged 13-19 who completed baseline and 16-month follow-up surveys. Prevalence of social media utilization and frequency, by sex and acculturation categories, was examined using generalized estimating equations. Results: Women are more likely to use SMS, but men are significantly more likely to SMS a girl/boyfriend (P=.03). The use of Internet by men and women to research health information increased over time. Facebook use declined over time (P<.001), whereas use of YouTube (P=.03) and Instagram (P<.001) increased, especially among women and more US acculturated youths. Conclusion: Social media is ubiquitous in Latino adolescents’ lives and may be a powerful mode for public health intervention delivery. %M 26420553 %R 10.2196/mhealth.4374 %U http://mhealth.jmir.org/2015/3/e89/ %U https://doi.org/10.2196/mhealth.4374 %U http://www.ncbi.nlm.nih.gov/pubmed/26420553
