Abstract
IntroductionNutritional disorders in childhood may cause a decline in motor abilities and increased morbidity and mortality in adulthood. ObjectiveTo assess the association between nutritional status and motor abilities. Materials and methodsA cross-sectional study was performed that included 12,872 children aged between 6 and 18years who underwent a clinical evaluation and various physical tests. ResultsAmong the children, 66% had a Tanner maturation stage1 and 2, 6% were under-nourished, and 12.2% were at risk of overweight and obesity. The obese children had a decrease in aerobic power (in 2.72mL O2 kg–1·min–1; 95%CI: 1.89 to 3.56; P<.001), speed (0.14m·sec; 95%CI: 0.06 to 0.22; P<.001), explosive strength (0.10m; 95%CI: 0.06 to 0.13; P<.001), agility, strength endurance and balance. Under-nourished children showed a decrease in speed (0.13m·sec; 95%CI: 0.06 to 0.20; P<.001), explosive strength (0.04m; 95%CI: 0.01 to 0 07; P<.004), and strength endurance. ConclusionsThere was an association between nutritional status and motor abilities in the children included in this study. Obese children showed the worst results in physical tests, and the under-nourished ones showed a decrease in speed, explosive strength and strength endurance.
