Abstract

Abstract

Objective To investigate the association between bedtime screen use and sleep health among fourth- and fifth-grade primary school students, so as to provide evidence to support interventions for improving sleep quality. Methods From April to June 2024, a survey was conducted among 4 232 fourth- and fifth-grade students from nine primary schools in a district of Beijing. A self-designed questionnaire assessed bedtime screen use behavior and sleep health indicators. Generalized linear models and Logistic regression were used to analyze the associations. Results Among the surveyed students, 28.3% reported bedtime screen use. Mean sleep duration every day was (9.31±0.90) hours on school days and (10.08±1.36) hours on weekends. Compared to non-users, students with bedtime screen use exhibited every day: later bedtimes on school days (10.18 min delay, 95%CI=6.88-13.47) and weekends (22.09 min delay, 95%CI=17.33-26.85) (P < 0.05); later weekend wake times (7.97 min delay, 95%CI=1.78-14.16, P < 0.05); reduced sleep duration on school days (-9.82 min, 95%CI=-13.62 to -6.03) and weekends (-14.12 min, 95%CI=-20.24 to -8.00) (P < 0.05); greater weekend-school day bedtime discrepancy (β=1.15, 95%CI=1.08-1.23, P < 0.01). Additionally, they had lower odds of falling asleep within 20 minutes (OR=0.62, 95%CI=0.54-0.72), daytime alertness (OR=0.66, 95%CI=0.56-0.77), and subjective sleep satisfaction (OR=0.57, 95%CI=0.49-0.66)(P < 0.01). Conclusions Bedtime screen use is associated with adverse effects on multiple dimensions of sleep health in primary school students. Reducing screen exposure before bed may help improve their sleep quality.
