title: [Evaluation of body composition by means of anthropometric measures in obese and non obese adolescents from two socioeconomic levels].
abstract: Anthropometric measures of 120 female adolescents were analyzed, 60 of them from a low socio-economic level (LSEL),and 60 from a high socio-economic level (HSEL), with 30 obese and 30 non-obese in each group, in an attempt to verify differences between the socio-economic levels in relation to the body-composition and the distribution of fat throughout the body. The weight,height, upper arm circumference and 4 skin folds (triceps, biceps,subscapular and suprailiac) were measured, and the arm muscle area, arm fat area and percentage of body fat were estimated. Those who were obese from LSEL presented an average height lower (p<0.05) than the obese from HSEL, and a greater proportion of this group presented a height deficit for their age. The arm muscle area was greater (p<0.05) in the obese from HSEL, but the percentage of body fat was similar in the two groups as well as the measures of the isolated skin folds. The increase in fat in the obese from LSEL, when compared with the non-obese, was 2.8 times greater than the muscle. In the HSEL, this increase was 1.3 times greater. It was concluded that the obese from both socio-economic levels presented different types of obesity in relation to body composition,but were similar in relation to body fat distribution.
