Social epidemiology of bedtime screen use behaviors and sleep outcomes in early adolescence.

Older age, female sex, sexual minority status, lower household income, and lower parent education were associated with increased bedtime screen use among 10,305 early adolescents.

• Black, Native American, and Latino/Hispanic adolescents reported more bedtime screen use compared to White adolescents, independent of household income or parental education.
• Increased bedtime screen use was linked to greater sleep disturbances, particularly in male adolescents.
• Shorter sleep duration was associated with more bedtime screen use, especially among female adolescents and those from households with higher income and parental education levels.
• Sexual minority identification was associated with higher bedtime screen use but did not correlate with worse sleep outcomes.
