Improving Sleep Health and Circadian Timing to Support Cardiometabolic Health in Adolescents
Starting soon · Not applicable
Conditions studied: Overweight Adolescents, Sleep, Insulin Sensitivity
In brief
Many teenagers get too little and late timed sleep. High body weight and diabetes are increasing in teenagers as well. This study plans to learn more about whether improving sleep habits can help improve how the body regulates blood sugar and energy use in teenagers who have higher body weight. To answer this question, the investigators plan to enroll teenagers who get \<7 hours of sleep on school nights and measure changes in blood sugars and energy use after two weeks of typical sleep (sleeping on their normal school schedule) and two weeks of a sleep intervention that includes spending longer time in bed at night, melatonin, and morning light.
