Insomnia Comorbidity and Impact and Hypnotic Use by Age Group in a National Survey Population Aged 16 to 74 Years

Abstract

The association between insomnia and impaired quality of life is most pronounced in older age groups. Associations with physical and mental health status and those with daytime fatigue do not vary in strength between age groups. Older people with insomnia in this population were more likely to be taking benzodiazepine hypnotics.
