Abstract

introduction: the estimation of body composition is an important study field in the prognosis and diagnosis of degenerative diseases. objective: to analyze the applicability of the body Adiposity index (bAi) and the skinfold thickness method. methods: the sample consisted of 19 young adult women with a mean age 24.53 ± 2.65 years, who underwent anthropometric measurements (circumferences and skinfold thickness) and dual energy x-ray absorptiometry (dexA). the estimated values were compared to the reference value by using the paired t test and by analysis of the level of association between the methods through the pearson correlation. the level of significance was p<0.05. results: showed no significant differences between the fat percentage estimated by the bAi and the reference values, however had moderate level of association (r=0.627). nevertheless, the skinfold thickness method showed statistically significant difference (p>0.05) with a strong association level (r = 0.879). conclusion: Although the bAi does not show difference to the estimated values, it is clear that further studies on the applicability of the method in the brazilian population are necessary.
