Weight was measured using a balance with a 100-g precision (Detecto; Lafayette Instruments Company, Lafayette, IN, USA). Height was measured in the upright position to the nearest millimeter (Holtain Ltd., Crymych, UK). Both assessments were undertaken with children in underwear and barefoot. BMI was calculated as body mass (kg)/height (m2).
Dual-energy X-ray absorptiometry was used to measure fat and lean mass (GE Lunar Prodigy; GE, Madison, WI, USA). All scan analyses were analyzed using GE Encore 2002 software Version 6.10.029. Participants were scanned wearing light clothing with no metal and no shoes or jewelry. Whole body scans were made in a supine position and were submitted to a regional analysis as previously described.25
