Wearables Reveal Sleep-Mental Health Link in Youth

JAMA Network

About The Study: Using Fitbit data in a longitudinal cohort of 3,393 young adolescents, 6 sleep health dimensions were identified: irregularity, timing, duration, social jetlag, weekend oversleep, and continuity. Greater irregularity was associated with higher concurrent transdiagnostic mental health symptoms, whereas shorter duration was associated with higher symptoms at 1-year follow-up. These findings demonstrate the multidimensional nature of adolescent sleep health and can help guide selection of sleep health domains and representative measures to enhance reproducibility and suggest potential intervention targets.
