Sabia S, Dugravot A, Léger D, Ben Hassen C, Kivimaki M, Singh-Manoux A (2022) Association of sleep duration at age 50, 60, and 70 years with risk of multimorbidity in the UK: 25-year follow-up of the Whitehall II cohort study. PLoS Med 19(10): e1004109. https://doi.org/10.1371/journal.pmed.1004109
Sleep duration has been shown to be associated with individual chronic diseases but its association with multimorbidity, common in older adults, remains poorly understood. (…) We observed short sleep duration to be associated with risk of chronic disease and subsequent multimorbidity. (…) We found a robust association of sleep duration ≤5 hours at age 50, 60, and 70 (separate analyses) with higher risk of incident multimorbidity. (…) These findings support the promotion of good sleep hygiene. (…) A major strength of this study is the long follow-up, repeated measures that allowed analyses on sleep duration at ages 50, 60, and 70.
