It’s always nice to have some evidence for what you think makes sense. David Katz and his Yale colleagues analyzed a bunch of studies attempting to improve both school nutrition and physical fitness. Taken one by one, these studies generally showed negligible improvements in body weight, if any. But these investigators analyzed a selected group of 19 (of 64) studies that met their inclusion criteria. Taken collectively, these studies showed that the interventions improved body weight. The overall effects on weight were small, but in the hoped-for direction. Katz et al’s conclusion: combined nutrition and physical activity interventions are worth doing, especially when they include parental involvement along with cutting down on TV.
