The purpose of this study was to assess the prevalence of sexting among sixth through twelfth grade students and its correlations with other risk behaviors. The survey was conducted in 35 different schools in a midwestern state. Overall, 17% of students engaged in sexting, which varied significantly by age (3% of 12-year-olds to 32% of 18-year-olds). Adjusted odds ratios found statistically significant correlations between sexting and sexual behaviors, substance use behaviors, emotional health behaviors, and time spent texting. Sexting should be addressed by parents, teachers, and mental health professionals who interact with adolescents. (Contains 3 tables.)
