Abstract
dc.description.abstract
Objectives: We assessed the agreement of body fat and fat-free mass measured by simpler methods
against the four-compartment model (4C).
Methods: In 60 obese schoolchildren (body mass index 95th percentile) between the ages of 8
and 13 y who were recruited from one school in Chile, multicompartmental body composition was
estimated with the use of isotopic dilution, plethysmography (BodPod), radiographic absorptiometry
(DEXA), and anthropometric equations. These results were compared to those of the 4C
model, which is considered the gold standard.
Results: For body fat, the 4C model showed the best agreement with DEXA for boys in Tanner stages
I and II (r ¼ 0.971) and with isotopic dilution for boys in Tanner stages III and IV (r ¼ 0.984). The
best agreement in girls occurred with isotopic dilution, regardless of pubertal stage (r ¼ 0.948 for
Tanner stages I and II; r ¼ 0.978 for Tanner stages III and IV). Both isotopic dilution and the Huang,
Ellis, and Deurenberg anthropometric equations underestimated body fat in boys; by contrast,
DEXA, BodPod, and the Slaughter equation overestimated body fat in boys. All of the equations
underestimated body fat in girls. For fat-free mass in both boys and girls, the 4C model showed the
best agreement with isotopic dilution, regardless of pubertal stage. The Huang equation showed
the best agreement for boys (r ¼ 0.730 for Tanner stages I and II; r ¼ 0.695 for Tanner stages III and
IV) and for girls in Tanner stages I and II (r ¼ 0.884). The Ellis equation had the best agreement for
girls in Tanner stages III and IV (r ¼ 0.917).
Conclusions: For obese Chilean children of both sexes, isotopic dilution and DEXA were the twocompartment
methods that had the best agreement with the gold-standard 4C model for both
body fat and fat-free mass; these were followed by the Huang and Ellis anthropometric equations.
