Resumen:
As a consequence of increasing prevalence of pediatric
obesity, accurate methods to determine body fat have been demanded.
Central obesity is related to cardiovascular risk factors.
For this reason, current determinations should distinguish body
fat distribution, and dual-energy X-ray absorptiometry (DXA)
provides helpful information. However, a lack of reference
values avoids its use in children.
Objective: To obtain reference values of % body fat (FM%)
and fat-free (FFM%) mass of entire body (total) and of different
areas (trunk tr, arms ar and legs le) in clinically healthy children
aged 2 to 6 years. Children (n=102; 48 boys (B) and 54 girls
(G)) attending a day care center at La Matanza, Argentina, were
evaluated. Body composition (total body and trunk tr, arms ar,
legs lg) as FM% and FFM% by DXA (DPX-L Densitometer,
Pediatric Software) were determined.
Results (mean ±SD): (a) FM% total B=20.16 ± 5.49,
G=26.01±6.04, tr B=14.88±4.76, tr G=20.24±5.58, ar B=
