NUTRITIONAL CONDITION OF SCHOOLCHILDREN AND THEIR ASSOCIATION WITH LEVELS OF FITNESS AND CARDIOVASCULAR RISK FACTORS

Abstract

in Chile, the increase of childhood obesity has become a major public health problem. The aim of the study is to determine and compare the levels of overweight and obesity of schoolchildren and their association with fitness levels and predictors of cardiovascular risk. an association study and comparison of variables by gender and nutritional status was performed, 113 students (58 men and 55 women) between 13 and 16 years old were evaluated. Nutritional condition and physical performance through the set used by the agency of quality of education in Chile was measured. 57.5% of the sample was overweight. The contour waist and fat percentage is higher in women (p < 0.05). BMI was not significantly different. Men had better physical performance in jumping, abdominal strength, and Navette Test (p < 0.05). Regarding the assessment of weight status on physical performance there were significant differences (p < 0.05) in the variables; abs, flexion and extension, Navette Test and jump higher results in subjects with normal weight. Obese school students had a higher percentage of fat mass and waist contour (p < 0.05). Regarding the association of variables according to BMI, body fat percentage and waist contour, these had negative associations with physical performance. 57.5% of the evaluated students were overweight or obese, associating these results negatively with physical performance, and increased levels of fat mass and waist contour, all these health indicators and predictors of cardiovascular risk.
