The present study aimed to verify the level of applicability of the BAI, compared to other indirect techniques for assessing body composition (BMI and DC). The purposive sample consisted of 60 male children aged between 10 and 14 years. Weight and height to calculate BMI were collected. Verification of the %BF, the protocol Slaughter suggests that the sum of the Skin Folds (DC) of the triceps and medial calf (TR + PM) was used. The calculation was performed by dividing the BAI to measure the hip circumference (cm); the height (m) multiplied by the square root of the height (m), and 18 decreases the final result. For the statistical analysis we used the MedCalc software, where they calculated the descriptive statistics (Mean and SD), the normality test for determining the Spearman correlation degree and also the method of Bland Altman was performed to verify the degree of agreement between BMI, BAI and %BF with a significance level of p<0.05. We used the chi-square, to determine the association between the percentage frequencies in results between anthropometric methods. Significant correlations between BMI x %BF (r= 0.738; p <0.001) were found; BAI x BMI (r= 0.678; p<0.001) and between BAI x %BF (r= 0.687; p <0.001). It is possible to conclude that the IAC can not be and need to diagnose body fat in children 10-14 years of age a viable tool.
