Study design: Observational Study
Abstract: Background: Screen exposure before bedtime may contribute to sleep disturbances in preschool children. This study aimed to assess the association between bedtime screen exposure and sleep disturbances among preschool children. Material and Methods: A hospital-based cross-sectional study was conducted among 210 children aged 3–5 years. Information regarding sociodemographic characteristics, bedtime screen exposure, and sleep-related problems was collected. Sleep disturbances were assessed using a screening approach covering bedtime problems, night awakenings, sleep duration and regularity, daytime sleepiness, and snoring. Associations were assessed using chi-square tests and multivariable regression analysis. Results: Bedtime screen exposure was reported in 126 (60.0%) children, while 91 (43.3%; 95% CI: 36.8–50.1) had at least one sleep disturbance. Sleep disturbances were more prevalent among children exposed to screens before bedtime than among unexposed children (55.6% vs. 25.0%; p<0.001). Their prevalence increased from 25.0% among children without exposure to 40.0%, 60.4%, and 62.8% among those exposed for 1–15, 16–30, and 31–60 minutes, respectively (p<0.001). In multivariable analysis, bedtime screen exposure (adjusted prevalence ratio [aPR]: 1.78; 95% CI: 1.24–2.56; p=0.002) and an irregular bedtime routine (aPR: 1.42; 95% CI: 1.03–1.96; p=0.032) were significantly associated with sleep disturbances. Conclusion: Bedtime screen exposure and irregular bedtime routines were associated with sleep disturbances among preschool children. Parental awareness and consistent bedtime practices may help promote healthy sleep habits. Keywords: Bedtime screen exposure
