OBJECTIVE The purpose of this study is to provide the first data on the prospective, reciprocal association between short sleep duration and DSM-IV anxiety disorders among adolescents. METHODS A community-based two-wave cohort study included 4175 youths aged 11-17 years at baseline, with 3134 of these followed up a year later, drawn from a metropolitan area with a population of over 4 million. Anxiety is defined as any DSM-IV anxiety disorder in the past year generalized anxiety: panic disorder, agoraphobia without panic, social phobia, and post-traumatic stress disorder. Short sleep duration is defined as ≤6 h of sleep per night. RESULTS/CONCLUSIONS In multivariate analyses, short sleep duration every night at baseline predicted anxiety disorders at follow-up, controlling for anxiety at baseline. Examining the reciprocal association, anxiety disorders at baseline did not predict short sleep duration at follow-up. We are the first to examine the reciprocal effects for anxiety disorders and sleep duration among adolescents using prospective data. The data suggest that reduced quantity of sleep may increase risk for anxiety, but anxiety does not increase risk for decreased sleep duration.
