ABSTRACT
BACKGROUND:
It is important to clarify the association of lean and fat mass between children and adolescents considering the rising prevalence of overweight and obesity in this age group. The aim of this study was to verify the association between the body adiposity index (BAI) and dual-energy X-ray absorptiometry (DXA) methods for analyzing body composition, as well as analyzing the validity of BAI to verify the percentage of fat in children and adolescents.METHODS:
The sample was composed of 106 children and adolescents, 44 females (age 11.5 ± 1.8 years) and 62 evils (13.6 ± 2.6 years). The body fat (%F) was measured using DXA and the doubly indirect BAI body fat estimation technique.RESULTS:
The BAI and DXA estimates of %F were strongly correlated (boys r = .71, P < .0001; girls r = .72, P < .0001). The linear regression analyses showed that BAI is significant to estimate the %F in total sample (P < .0001). For boys, the %F analyzes performed by BAI and DXA did not show any differences when compared (P = .2). In addition, BAI pointed out a significant proportion bias for both sexes (P < .0001), which suggests its inefficiency in the analysis of %F.CONCLUSIONS:
BAI and DXA correlate; however, there is low reliability and a high proportion bias for the analysis of %F by BAI.
