Be a Fit Kid: nutrition and physical activity for the fourth grade.

This article describes the inclusion of Be a Fit Kid in the fourth-grade curriculum. Be a Fit Kid is a fitness-emphasized physical activity and heart-healthy nutrition education program for elementary school children. Five parent—education lessons were offered and nutrition workbooks were distributed to parents. Following the 10-week intervention, significant improvements in fitness, body fat, nutrition knowledge, dietary habits, and levels of lipids and lipoproteins were observed in the intervention group compared with baseline levels. Changes in fitness, body fat, and nutrition knowledge were significant compared with the control group. These findings suggest that comprehensive physical activity and nutrition programs included in the school curriculum may be effective for improving cardiovascular health and reducing future risk for lifestyle-related diseases.
