Abstract:
Objective:To understand the impact of screen time on duration and quality of sleep, so as to provide scientific basis for the development of interventions.
Methods:A total of 3 584 preschool children in Haikou City were selected by stratified sampling method from March to June in 2022, and the Children s Sleep Habits Questionnaire (CSHQ) and self designed questionnaire were used.
Results:The average sleep duration of preschool children was (10.41±0.98)h/d, the rate of sleep deprivation was 28.71 %, and the report rate of sleep problems was 50.47%. The average sleep duration in general as well as on weekdays and weekends decreased by age ( F=21.00, 29.53, 3.26, P ＜0.05), and insufficient sleep duration rate significantly varied by age groups ( χ 2=29.85, P ＜ 0.01 ). The average screen time was (1.15±0.37)h/d, and the screen exposure rate was 55.39%. The total sleep problems ( 52.14 %), poor bedtime habits (43.02%), daytime sleepiness (67.10%), irregular sleep duration (53.05%), and abnormal sleep latency ( 24.99 %) were all higher than those in the non exposed group (48.41%, 39.59%, 63.29%, 48.91%, 19.57 %) ( χ 2= 4.94 , 4.31, 5.69 , 6.08, 14.85, P <0.05). Multiple linear regression analysis showed that age and weekend average screen time were negatively associated with sleep duration ( β =-0.01, -0.06), weekday and weekend average outdoor activity duration were positively correlated with sleep duration ( β =0.08, 0.08) ( P <0.05).
Conclusion:Screen exposure to preschool children s sleep time,sleep quality was closely related. Parents should cultivate good sleep habits of preschool children, and limit children s screen time to maximize outdoor activities, so as to ensure healthy development of children.
