Question: What is the long-term and bidirectional association between sleep duration and symptoms of psychiatric disorders in school-aged children?
Findings: In this population-based cohort study of 799 Norwegian children participating in the Trondheim Early Secure Study, when all time-invariant confounders and baseline levels of study variables were accounted for, short sleep duration was prospectively associated with symptoms of psychiatric disorders at younger but not older ages. No evidence was found for the opposite direction of association.
Meaning: This study found that short sleep duration was associated with the development of symptoms of psychiatric disorders, but symptoms of psychiatric disorders were not associated with reduced sleep.
