Study Summary
There is strong reason to believe that sleep promotion during adolescence could yield long-term health rewards; the investigators' data show that, when they get more sleep, Morning Larks have impressively reduced intake of overall calories and foods high in glycemic load that are linked to long-term health risk. Before that can be translated into major public health interventions, however, the field needs to understand why similar changes in sleep had no effect, or even an adverse effect, on adolescent Night Owls. This experimental study will clarify why there have been such discrepant effects across Morning Larks and Night Owls, with the goal of more broadly harnessing the promise of improved sleep in the prevention of obesity and long-term morbidity.
Primary Outcome
Trained interviewers will engage adolescents in 30-min interviews regarding food consumption over the previous 24-hr periods. This method has been validated in youth against doubly labeled water and weighed diet diaries. Such interviews are relatively unobtrusive, measure the nature, timing, and volume eaten, and allow for professional cuing to promote recall accuracy. Recall interviews will be conducted blind to the alignment vs. misalignment randomization, as will conversion to nutritional dat
