Investigating the association between sleep and aspects of mental health in children : findings from the Canadian Health Survey on Children and Youth.

Résumé

Introduction: Sufficient sleep and good quality sleep are crucial aspects of children’s healthy development. While previous research has suggested associations between sleep and positive mental health, few studies have been conducted in Canadian children. Methods: This study used data from the 2019 Canadian Health Survey on Children and Youth. Parents of children aged 5 to 11 years (N = 16 170) reported on their children’s sleep habits and mental health. Descriptive statistics were used to calculate means and percentages for sleep and mental health indicators. Logistic regression was used to compare mental health outcomes by meeting sleep duration recommendations (9–11 hours of sleep vs. < 9 or > 11 hours of sleep), sleep quality (difficulties getting to sleep) and having enforced rules for bedtime. Results: Overall, 86.2% of children aged 5 to 11 years met sleep duration recommendations (9–11 hours of sleep), 90.0% had high sleep quality and 83.1% had enforced rules for bedtime. While 83.0% of children had high general mental health, mental health diagnoses were reported for 9.5% of children, and 15.8% of children required or received mental health care. High sleep quality was consistently associated with better mental health, enforced rules for bedtime were associated with some negative mental health outcomes and meeting sleep duration recommendations tended not to be associated with mental health outcomes. Conclusion: Sleep quality was strongly associated with mental health among children in this study. Future research should explore longitudinal associations between sleep and mental health in Canadian children.
