The enduring effects of early-childhood adversities and troubled sleep among Canadian adults: a population-based study

Abstract

Objective: Although many studies have consistently found that early-childhood adversities are important risk factors for physical and mental health problems later in adulthood, few have examined the association between early-childhood adversities and troubled sleep. The objective of this study was to examine the association between early-childhood adversities and troubled sleep among adult Canadians.

Methods: Data for this paper (N = 19,349) were obtained from Statistics Canada's 2012 Canadian Community Health Survey-Mental Health (CCHS-MH). Logistic regression analysis was conducted to examine the association between early childhood adversities and troubled sleep, while accounting for various sociodemographic, socioeconomic, health, and mental health factors.

Results: Of the 19,349 respondents examined, 2748 representing 14.2% had troubled sleep. Controlling for sociodemographic, socioeconomic, health, and mental health factors, it was observed that for each additional childhood adversity experienced, the odds of having troubled sleep increased by 10% (odds ratio = 1.10, p <0.001, 95% confidence interval = 1.07-1.13). In addition, psychological distress, older age, being female, being unmarried, being white, a lower annual income, chronic pain, poor perceived health, and mental health difficulties were associated with troubled sleep.

Conclusion: The results of this paper provide population-based evidence for childhood adversities as a major predictor of troubled sleep in adulthood. The long-standing effects of these adversities on sleep highlight the importance of early detection, such as consistent assessment of sleep habits for children, adolescents, and adults, who have experienced childhood adversities, in health and mental health settings.
