To the Editor: Dr Davis and colleagues1 reported that a 13-week after-school exercise program for overweight children resulted in significant reduction in diabetes risk, as measured by decreased fasting insulin, insulin response to oral glucose, and body mass index z score, and increased aerobic fitness. The approach used (ie, moderate intensity group sessions with a variety of games and activities for 20-40 minutes) could readily be adapted in other communities at relatively modest cost. This study therefore provides encouragement for promoting exercise in sedentary youth.
