Distribución de la adiposidad en adolescentes mediante el índice de conicidad / Body fat distribution in adolescents by conicity index

RESUMO

Body regional fat distribution has been linked with a metabolic atherogenic risk profile, that starts early in life. Data from a cross-sectional sample of 394 boys and girls, 11 to 16 years, who inhabit a slum sector of Caracas, Venezuela was studied using Conicity Index (C) [equation see text] by means of Box-plot diagram, Levene, ANOVA, and Scheffe tests. The accepted level of significance was p < 0.05. Results showed significant differences in body fat distribution between age groups. Height and body mass index were used as control variables. C values ranged between (1.02-1.18) in boys and (0.99-1.14) in girls. Boys attained higher mean values. All groups showed variance homogeneity (p value > 0.05) and sexual dimorphism was found at 11, 12 and 13 years, that were removed after controlling for height and body mass index. Differences according to age groups in boys, were removed after controlling for height. Results found conicity index as an alternative method to assess abdominal fat distribution during adolescents years.
