Lela McKnight-Eily, Ph.D., and her colleagues, all of the CDC’s National Center for Chronic Disease Prevention and Health Promotion, used data from the 2007 national Youth Risk Behavior Survey of 12,154 U.S. high school students, a biennial self-administered survey designed to produce data representative of public and private school students in grades 9 through 12. They assessed hours of sleep by asking students, “On an average school night, how many hours of sleep do you get?” Responses were dichotomized into “insufficient sleep” (fewer than eight hours) and “sufficient sleep” (eight or more hours).


The students were also asked about several health-risk behaviors, including non-diet soda consumption; lack of physical activity; hours spent watching television; hours spent playing video or computer games or using a computer for a reason not related to school work; use of cigarettes, alcohol, or marijuana; sexual intercourse; feelings of sadness or hopelessness; and serious consideration of suicide.
Insufficient sleep was associated with 10 of the 11 health-risk behaviors examined. For all 10, students who reported insufficient sleep had higher odds of engaging in the risk behavior than did students who reported sufficient sleep. There was no association between insufficient sleep and watching television for more than three hours a day overall, but the association was significant among male students, but not among females.
