Adolescent sleep, risk behaviors, and depressive symptoms: are they linked?
OBJECTIVE
To explore how weekday and weekend sleep patterns are related to adolescent substance use, depressive symptoms, and school truancy.


METHODS
Selfreport surveys of 242 youth (93.4% white, mean age 16.4 years).


RESULTS
Longer weekday sleep duration was inversely associated with depressive symptoms, past month alcohol use, and drunkenness. Later weekend bedtime and wake-times, compared to those of weekdays, were associated with increased substance use and truancy.


CONCLUSIONS
Weekday sleep duration appears to be protective for substance use, depression and school truancy for teenagers. However, inconsistent sleep patterns between weekdays and weekends were associated with a range of markers for adolescent risk.
