Abstract summary 

To examine specific sleep characteristics of adults living in Canada according to sex, gender, ethnoracial background, socioeconomic status, immigration status, sexual orientation, and language spoken at home.This cross-sectional and nationally representative study used self-reported data from the 2021 Canadian Community Health Survey (n = 39,346 adults aged 18 years and older). Sleep characteristics (sleep duration, nighttime insomnia symptoms, unrefreshing sleep, and difficulty staying awake) were assessed and compared across groups.Females were more likely than males to report nighttime insomnia symptoms (23.1% vs. 14.8%) and unrefreshing sleep (17.2% vs. 13.5%). The same was also observed for gender identity. Although White respondents were more likely to meet sleep duration recommendations (58.3%), they had the highest prevalence of nighttime insomnia symptoms (20.9%) compared to respondents with other ethnoracial backgrounds. Respondents coming from lower socioeconomic backgrounds were more likely to report poorer sleep compared to those coming from higher socioeconomic backgrounds. Insomnia symptoms were lower among immigrants (13.9%) compared to nonimmigrants (21.1%). Respondents with a sexual orientation not classified as heterosexual, gay, or lesbian reported poorer sleep. Finally, for language spoken at home, those who responded "French only" were more likely to meet sleep duration recommendations (64.1%) and were less likely to report unrefreshing sleep (8.8%). Nighttime insomnia symptoms were the lowest among those who reported speaking a language other than French or English at home (9.5%).This study highlights important sleep disparities among Canadians. Future intervention strategies should aim to reduce sleep health disparities.
