- Abstract
OBJECTIVE:: To assess the impact of a 6 months nutrition education and physical activity intervention on primary school children through changes in adiposity and physical fitness. DESIGN:: Longitudinal school-based controlled evaluation study. SUBJECTS:: Children from 1st to 8th grade, 2141 in intervention and 945 in control schools. INTERVENTION:: Nutrition education for children and parents, ‘healthier’ kiosks, 90?min of additional physical activity (PA) weekly, behavioral PA program and active recess. MEASUREMENTS:: Adiposity indices (BMI, BMI Z-score, triceps skinfold thickness (TSF), waist circumference and physical fitness (20?m shuttle run test and lower back flexibility). RESULTS:: Positive effect on adiposity indices (except TSF) was observed in boys (P<0.001 for BMI Z), while both physical fitness parameters increased significantly in both boys (P<0.001 for each test) and girls (P<0.0001 for each test). A differential effect in BMI Z was observed according to baseline nutritional status. CONCLUSIONS:: This intervention showed a robust effect on physical fitness in both genders and decreased adiposity only in boys.International Journal of Obesity (2004) 28, 483-493. doi:10.1038/sj.ijo.0802611 Published online 2 March 2004
