​Summary: This study investigated the prevalence of technology-use rules, typical sleep habits, and associations between rules and sleep using the representative 2017–2018 California Health Interview Survey adolescent sample.

Adolescents aged 12–17 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.

Findings: 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.

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.
