We estimate prevalence, incidence and persistence of short sleep or sleep deprivation in a two wave cohort study of 4175 youths 11-17 years old at baseline and 3134 of these a year later. Data were collected using computer interviews and questionnaires. Sleep deprivation was defined as 6 h or less per night during the past 4 weeks. Weighted logistic regression procedures were employed to calculate prevalence, incidence, persistence/chronicity, and odds ratios. Prevalence rates and rates of persistence suggest sleep deprivation is highly prevalent and chronic. Multivariate analyses indicate that short sleep increases risk across multiple domains of dysfunction, suggesting pervasive deleterious effects. The broad impact of sleep deprivation and its pervasiveness suggests interventions will need to focus on multilevel changes to increase sleep time and reduce the negative impact of sleep deprivation among adolescents. © 2009 The Association for Professionals in Services for Adolescents.
