abstract="STUDY OBJECTIVES: To assess the effects of delayed high-school start times on sleep and motor vehicle crashes. METHODS: The sleep habits and motor vehicle crash rates of adolescents from a single, large, county-wide, school district were assessed by questionnaire before and after a 1-hour delay in school start times. RESULTS: Average hours of nightly sleep increased and catch-up sleep on weekends decreased. Average crash rates for teen drivers in the study county in the 2 years after the change in school start time dropped 16.5%, compared with the 2 years prior to the change, whereas teen crash rates for the rest of the state increased 7.8% over the same time period. CONCLUSIONS: Later school start times may both increase the sleep of adolescents and decrease their risk of motor vehicle crashes.<p /> <p>Language: en</p>",
