—Dr Garrison and colleagues point out an important conclusion that may be drawn from the CATCH findings. Obesity is epidemic in the United States.1 Most agree that this is attributable to a combination of increased energy intake (food) and decreased energy expenditure (physical activity). CATCH demonstrated increases in vigorous physical activity at school and home plus lower food energy intake while maintaining essential nutrient intake. Programs such as CATCH offer methods for elementary schools to improve their students' health through increased physical activity and better eating patterns.2 However, the durability and long-term effects of CATCH are still unknown. A 3-year follow-up of the CATCH cohort (with more than 4000 students) supported by the National Heart, Lung, and Blood Institute is currently under way.
