Objectives:
This article estimates the prevalence of insomnia among Canadians aged 15 or older, and factors related to it. Associations between insomnia and coping ability, work status, two-week disability days and life dissatisfaction are analyzed.
Data Sources:
The data are from the 2002 Canadian Community Health Survey: Mental Health and Well-being.
Analytical Techniques:
Cross-tabulations were used to estimate the prevalence of insomnia by selected characteristics. Associations between these characteristics and insomnia, and between insomnia and selected negative situations, were examined in multivariate logistic regression models.
Main Results:
In 2002, an estimated 3.3 million Canadians (13.4% of the household population aged 15 or older) had insomnia. Factors independently associated with insomnia included painful chronic conditions, activity limitations, mood and anxiety disorders, life stress, frequent use of alcohol or cannabis, obesity, and low education. Compared with those who did not have insomnia, people with insomnia were more likely to report negataive situations such as difficulty coping and not having a job.
