This study investigated the prevalence of technology-use rules, typical sleep habits, and associations between rules and sleep using the representative 2017e2018 California Health Interview Survey adolescent sample. Methods: Adolescents aged 12e17 years completed the California Health Interview Survey, including queries of (1) rules at home regarding times to turn off or put away electronics and (2) school-night bedtime and rise time. Rates of rules and associations between rules and sleep were investigated using descriptive statistics and bivariate and multivariable analyses. Results: Seventy-two percent reported technology-use rules. Rates were comparable across subgroups. Rules and sleep were not significantly associated after adjusting for covariates. Reported time in bed fell below National Sleep Foundation guidelines for 38% of participants. Conclusions: Most adolescents reported technology-use rules at home. Associations between rules and bedtime were mixed, suggesting that further exploration of contextual and developmental factors is needed. Many reported inadequate sleep duration, supporting sleep as a key topic in adolescent health.
