title: [Brachial indicators of fat and muscle in schoolchildren of a rural community according to social groups (General Lavalle, Buenos Aires, Argentina)].
abstract: In order to determinate the body composition in a schoolchildren rural community--General Lavalle, Buenos Aires, Argentina--the arm circumference (AC) and the triceps skinfold (TS) growth were studied by cross-sectionally methods. From those measurements the arm muscle area was calculated. All the data were transformed to "Z" scores. The sample was divided into seven social groups according to the educational and occupational levels of parents. Statistics analysis of variance (ANOVA test) and Tukey test were performed. Statistically significant differences in AC an TS among the social groups were observed (p < 0.001). Two different patterns of brachial composition were observed according to the social group. This composition was different with respect to urban populations. Our findings suggest an environmental adaptation by growth.
