The association between family function and sleep disturbances of preschool children in rural areas of China: a cross-sectional study

This study aimed to explore the association between family function and sleep disturbances in preschool children in rural areas of China. Caregivers of preschool children completed sociodemographic questionnaires, the Children's Sleep Habits Questionnaire (CSHQ), the Self-rating Anxiety Scale (SAS) and the Family APGAR scale. Using sleep disturbances in children as the dependent variable, family function and other related factors as independent variables, binary logistic regression analyses were performed to examine associations between family function and sleep disturbances in children. A total of 3,636 caregivers of preschool children were enrolled in our study, and the prevalence of sleep disturbances among their preschool children was 89.4%. In our study, lower family function was associated with higher risk of sleep disturbances among preschool children. After adjusting for age (years), education level of mother, discipline attitudes of father and mother, only child status and caregivers' anxiety, the associations were statistically significant both in families of which caregivers of children are their parents or other relatives. (AOR for parents = 1.487, 95% CI:1.152-1.919, P = 0.002; AOR for other relatives = 1.963, 95% CI:1.302-2.958, P = 0.001). Our study results indicated that family function was associated with sleep disturbances in preschool children, and future high-quality cohort studies are needed to explore this topic in more detail.
