Abstract
Introduction: In Chile, the prevalence of obesity in schoolchildren is 21.3%. The study and individual intervention of this malnutrition, it is necessary to have not only global indicators of nutritional status, but also indicators that give information on body composition. Objective: To compare estimates of body fat isotopic dilution, plethysmography and radiographic absorptiometry 4C model in overweight schoolchildren. Methods: We worked with 61 obese (BMI ≥ p 95) of both sexes, between 8 and 13 years, enrolled in a school in a district of the city of Santiago. The multicompartmental body composition determination, considered isotopic dilution, plethysmography and radiographic absorptiometry. Using as a reference standard four compartment model of Fuller. Results: In both sexes, the method showed better agreement with the reference of 4 compartments was isotope dilution (r = 0.98, p < 0.01). In children, the isotopic dilution underestimates body fat in -0.40 kg. By contrast, DEXA and
