TLDR
Recommendations for East Asian populations may need to be considered in the context of sex and age, as all other sleep durations were associated with a significantly increased mortality risk.
Abstract
Key Points Question What is the association between sleep duration and mortality outcomes in individuals from East Asia? Findings In this cohort study of 322 721 adult participants, when compared with 7 hours, all other sleep durations were associated with a significantly increased mortality risk. Age and sex were significant modifiers of the associations between sleep duration and death from all causes (age), cardiovascular disease (sex), cancer (age and sex), and other causes (age and sex), and age was a modifier of the association only among men. Meaning These findings suggest that sleep duration recommendations for East Asian populations may need to be considered in the context of sex and age.
