Educational intervention improves 4th-grade schoolchildren's nutrition and physical activity knowledge and behaviors

Many obesity interventions have taken place in clinical settings; however, schools are ideal places to develop and implement innovative interventions designed to prevent childhood obesity. The findings of this study indicate that the nutrition and physical activity intervention was significantly related to change in knowledge, food consumption, food-related behaviors, and physical activity behaviors. Scores of students in the intervention classrooms were significantly higher than those of students in the control classrooms. These improvements were maintained at the 5-month follow-up.
