About The Study: The findings of this study show a broad increase in insufficient sleep across all demographic groups, driven largely by increasing reports of very short sleep (5 hours or less). Notably, insufficient sleep increased as much or more among students without behavioral risks, suggesting that structural and environmental factors affecting most adolescents, rather than specific behaviors such as electronic media use, substance use, or sedentary activity, are contributing to wide spread sleep loss. These trends highlight the need for population-level rather than targeted interventions.
