Area of Science:

  • Epidemiology
  • Public Health
  • Mental Health Research

Background:

  • Insomnia is a prevalent sleep disorder affecting a significant portion of the adult population.
  • Understanding the factors associated with insomnia is crucial for developing targeted public health interventions.
  • Previous research has identified various demographic, health, and lifestyle factors linked to insomnia, but Canadian-specific data is essential.

Purpose of the Study:

  • To estimate the prevalence of insomnia among Canadians aged 15 and older.
  • To identify demographic, health, and lifestyle factors independently associated with insomnia in the Canadian population.
  • To analyze the relationship between insomnia and negative life situations, including coping ability, employment status, disability, and life satisfaction.

Main Methods:

Related Experiment Videos

  • Utilized data from the 2002 Canadian Community Health Survey: Mental Health and Well-being.
  • Employed cross-tabulations to determine insomnia prevalence across various characteristics.
  • Conducted multivariate logistic regression analyses to examine associations between insomnia and related factors.

Main Results:

  • An estimated 3.3 million Canadians (13.4%) aged 15 and older reported insomnia in 2002.
  • Independent risk factors for insomnia included chronic pain, activity limitations, mood/anxiety disorders, life stress, substance use (alcohol, cannabis), obesity, and lower education levels.
  • Individuals with insomnia were more likely to report difficulties with coping and unemployment compared to those without insomnia.

Conclusions:

  • Insomnia affects a substantial segment of the Canadian population and is associated with a wide range of adverse health and socioeconomic factors.
  • The findings highlight the need for integrated approaches to address insomnia, considering its links to chronic conditions, mental health, and lifestyle.
  • Public health strategies should focus on early identification and management of insomnia, particularly among vulnerable populations identified in the study.
