Epidemiology of Insomnia: Prevalence, Course, Risk Factors, and Public Health Burden

Charles M Morin et al. Sleep Med Clin. 2022 Jun.

Abstract

This article summarizes epidemiologic evidence on insomnia, including the prevalence, incidence, and risk factors, as well as its course and consequences. Approximately 10% of the adult population suffers from an insomnia disorder and another 20% experiences occasional insomnia symptoms. Women, older adults, and people with socioeconomic hardship are more vulnerable to insomnia. Insomnia is often a chronic condition, with a 40% persistence rate over a 5-year period. Insomnia is a significant public health problem that should be addressed at the individual level with appropriate clinical care and at the population level with large-scale sleep health interventions.

Keywords: Epidemiology; Incidence; Insomnia; Prevalence; Risk factors; Sleep disorders.
