This work aims to investigate to what extent the variables related to weight, height and waist circumference
(WC) of the Brazilian Air Force Command Militaries (COMAER) between 20 and 30 years old, assessed by the
Physical Fitness Assessment Test (PFAT) in 2012, correlate with body fat percentage (%BF). The research group
consisted of 986 men and 196 women from 10 different Military Organizations from the COMAER. The body
mass index (BMI), the waist circumference, the waist-to-height ratio (CER), and the waist product - BMI (WPBMI)
were the independent variables and the %BF estimated by skinfold, was the dependent variable. The highest
values for men, found for the Pearson correlation coefficient (r), were 0.709, when combined with WPBMI, and
0.624 for women, when associated with BMI. The regressions of %BF had coefficients of determination (R2
) of 59.6% for CC and 64.2% for WPBMI, when taking into account gender and age. In conclusion, the correlations
must be used with caution in determining %BF. Nevertheless, this research revealed that the WPBMI, because
it is an index linked to the amount and distribution of body fat, has the potential to be a new indicator in the
clinical evaluation of body composition. It is suggested the execution of new research to clinical validation of
WPBMI, and the adoption of other sites for the determination of %BF using anthropometric variables.
