Future. Results of this preliminary study will shed light on the impact of a sleep and media use intervention for adolescents in reducing obesity and risk for type 2 diabetes in adolescents. These data will provide support for a future R01 submission testing the effectiveness of a sleep intervention in the context of a larger, well-powered study. It will also provide the foundation for further testing of the mechanisms of action in the relationship between sleep and obesity and type 2 diabetes.
