Longitudinal associations between insomnia symptoms and all-cause mortality among middle-aged and older adults: a population-based cohort study.

ABSTRACT: To date, there is no scientific consensus on whether insomnia symptoms increase mortality risk. We investigated longitudinal associations between time-varying insomnia symptoms (difficulty initiating sleep, difficulty maintaining sleep, early-morning awakening, and nonrestorative sleep) and all-cause mortality among middle-aged and older adults during 14 years of follow-up.
