Evaluation of Social Media Utilization by Latino Adolescents: Implications for Mobile Health Interventions

BACKGROUND Trends in social media use, including sending/receiving short message service (SMS) and social networking, are constantly changing, yet little is known about adolescent's utilization and behaviors. 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.
