Abstract:
Objective:To explore sleep duration and associated factors among children aged 3-6 years old in Zhejiang Province.
Methods:A total of 7 034 children aged 3-6 years from 24 kindergartens in Zhejiang province were selected through clustered sampling method. Through parental questionnaire, child sleep duration and associated factors were colleted. Possible influencing factors of sleep insufficiency were analyzed by logistic regression model.
Results:The rate of insufficient sleep was 56.1%, with 57.1% for boys and 55.1% for girls in Zhejiang Province. The rate of insufficient sleep increased with the increase of age, which was 46.7%, 49.8%, 50.2%, 55.2%, 64.0%, 65.8% and 68.1% for 3.0, 3.5, 4.0, 4.5, 5.0, 5.5 and 6.0 years old group (χ 2=45.71, P<0.01), respectively. The rate of insufficient sleep was 59.9%, 54.7% and 45.6% for children with <1 h/d, 1-2 h/d and ≥2 h/d outdoor physical activity (χ 2=67.10, P<0.01). Multivariate Logistic regression model showed that children older than 4.5 years old, whose caregiver was other than parents, outdoor activity time< 1 h/d and 1-2 h/d, maternal education below junior middle school and senior high school were positiviely associated with sleep insufficiency [OR(95%CI) was 1.29(1.07-1.54), 1.97(1.64-2.37), 2.04(1.69-2.46), 2.35(1.82-3.03), 1.21(1.08-1.35), 1.73(1.49-2.01), 1.47(1.26-1.72), 1.35(1.15-1.59), 1.16(1.01-1.32), P<0.05].
Conclusion:Sleep insufficiency among preschool children is associated with multiple factors, increase of age, insufficient outdoor activity and overdose screen time in particular. The finding calls for outdoor physical activity promotion among preschool children, especially for those whose caregivers are those other than parents.
