title: [The evaluation of body composition in children by anthropometry and impedance measurement].
abstract: Several anthropometric parameters (weight, height, thickness skinfolds, and body circumferences) together with the bioelectric impedance (BIA) were measured in a group of 407 healthy prepuberal children (205 males, mean age +/- SD: 6.8 +/- 1.6 years; 202 females, mean age +/- SD: 6.6 +/- 1.6 years) who did not practice any competitive sport. The group was divided into six weight classes (underweight to obese 3). The average values of the anthropometric data, BIA, FM (which is derived from the thickness skinfolds and BIA), TBW (derived from BIA), AFA and AMA (both derived from the forearm circumference and triceps skinfold) were all evaluated in relation to sex and weight classes. The average values of all the measured thickness skinfolds, FM and AFA were higher in the females. When considering the body circumferences, only the wrist circumference showed a statistically significant difference between sexes, being higher in males. In contrast both the rates waist/hips circumferences and waist/thigh circumferences were higher in males. As far as the BIA and FM average values is concerned, these were higher in females. The average value of FM derived from measuring the thickness skinfolds (males = 17.65 +/- 4.89%: females = 23.81 +/- 4.72% of body weight) proved higher than that one derived from BIA (males = 17 +/- 9.02%; females = 19.27 +/- 9.18%). The analysis of anthropometric and BIA data in relation to the weight classes showed significant variations of the mean values, except the rates waist/hips circumferences and waist/thigh circumferences. Therefore our data seem to exclude the presence of any difference of the fat distribution between sexes in paediatric age.(ABSTRACT TRUNCATED AT 250 WORDS)
