COVID-19 pandemic: demographic and clinical correlates of disturbed sleep among 6,041 Canadians.

As the pandemic continues, more Canadians are likely to develop sleep problems, an important consideration for planning mental health services.KEY POINTSThis is the first study to examine the prevalence rates and demographic and clinical correlates of disturbed sleep in a large sample (n = 6041) of Canadians during the COVID-19 pandemic.Prevalence of disturbed sleep was high at 77.8%.Individuals aged 41-60 years were twice as likely to present with sleep disturbance compared to individuals ≤25 years (OR 1.89, 95% CI: 1.27-2.81).Individuals with moderate/high anxiety symptoms, moderate/high stress symptoms, and suicidal ideation/thoughts of self-harm had higher likelihood of developing sleep disturbance, compared to individuals lacking these symptoms [(OR 4.05, 95% CI: 3.33-4.93) and (OR 2.42, 95% CI: 1.98-2.94)], respectively.As the pandemic continues, with fear of multiple waves, more Canadians are likely to develop sleep problems, an important consideration for planning the provision of mental health services.
