The survey questions about insomnia were identical in all CHMS cycles. Only the percentage of individuals with insomnia symptoms of 1 year or more was presented in the tables the other response categories could not be shown due to small sample sizes and coefficients of variation that were too unreliable to be published (more than 33.3%). The duration of insomnia symptoms was determined by the question, “How long have you had this trouble?” The five response options were: less than 2 weeks 2 weeks to less than 6 months 6 months to less than 1 year 1 year to less than 2 years and 2 years or more. Nighttime insomnia symptoms were determined by the question, “How often do you have trouble going to sleep or staying asleep?” Response options included “never,” “rarely,” “sometimes,” “most of the time” and “all of the time.” Respondents who answered either “most of the time” or “all of the time” were considered to have nighttime insomnia symptoms, as previously reported. From the responding households, 88.3% of participants completed the household questionnaire in Cycle 1, 90.5% in Cycle 2, 88.4% in Cycle 3, and 91.5% in Cycle 4. Response rates for selected households were 69.6%, 75.9%, 74.1% and 76.4% for cycles 1, 2, 3 and 4, respectively. Parents/guardians reported the information for respondents younger than 12. Respondents answered an interview-administered questionnaire in their home, including seven questions on sleep. Ethics approval for the CHMS was obtained from Health Canada’s Research Ethics Board. Residents of First Nations Reserves or other Aboriginal settlements, institutions and some remote regions, and full-time members of the Canadian Forces were excluded. The data are from cycles 1 to 4 (2007 through 2015) of the Canadian Health Measures Survey (CHMS), an ongoing nationally representative, cross-sectional survey of the household population aged 3 to 79 conducted by Statistics Canada. This article summarizes key findings on the prevalence of nighttime insomnia symptoms among Canadians aged 6 to 79 to inform policy decisions. The Canadian Health Measures Survey (CHMS) questioned Canadians between 20 on their sleep habits. A better understanding of the epidemiology of insomnia symptoms in Canada is important to guide resource allocation and inform the development of effective interventions. The present article aims to address this knowledge gap, and builds on Tjepkema’s study by also providing data on the duration of nighttime insomnia symptoms among Canadians. Furthermore, it is unknown whether school-aged children and adolescents in Canada also report high prevalence of nighttime insomnia symptoms. Note 7 However, it is largely unknown whether nighttime insomnia symptoms have remained stable in recent years in Canada. Note 4 Note 5 Note 6 Tjepkema reported that 13.4% of Canadian adults aged 15 or older had nighttime symptoms of insomnia in 2002 that is, they had difficulty going to sleep or staying asleep most of the time or all of the time. Note 4 Note 5 Note 6 For example, it is estimated that about 25% of adults are dissatisfied with their sleep, 10% to 15% report symptoms of insomnia associated with daytime consequences, and 6% to10% meet criteria for an insomnia disorder. The prevalence of insomnia in epidemiological studies can range from 6% to 48% depending on the definition used ( i.e., insomnia symptoms, with or without daytime consequences, dissatisfaction with sleep, and insomnia disorder). Note 1 Note 2 There is a clear need to develop more cost-effective, efficient and accessible therapies for insomnia. Note 3 Despite its high prevalence and burden, insomnia is often unrecognized and untreated because of barriers to its assessment and management. Note 1 Note 2 In Canada, the individual economic burden of insomnia is estimated at $5,010 per person per year, with nearly 90% of this amount attributed to indirect costs such as work absenteeism and reduced productivity. Note 2 Persistent insomnia has been associated with adverse health outcomes, including reduced quality of life and physical and psychological morbidity. Note 1 Insomnia is predominantly characterized by dissatisfaction with sleep and difficulties initiating or maintaining sleep, along with substantial distress and impairments of daytime functioning. Insomnia is the most prevalent sleep disorder and affects a large proportion of the population on a situational, recurrent or chronic basis. For this article… Abstract Tables and figure
