Abstract

PURPOSE: The purpose of this study was to compare the body fat percentage (BF%) values estimated with various body mass index (BMI)-based BF% equations and bioelectrical impedance (BIA). METHODS: One hundred and eighty-three female young adults (age=20.5±1.8 years, BMI=21.5±3.1kg/m2) participated in the study. Height and body mass were measured to calculate BMI. BF% was determined by BIA and predicted using BMI-based equations (BMIDE; BMIJA; BMIWO; BMIGA). RESULTS: Dependent t-test results revealed that there was no significant difference (P>0.05) in BF% between BIA and BMIJA. However, significant differences (P<0.01) were found between BIA and all other equations in BF%. The magnitude of difference, when compared to BIA, was trivial for BMIJA (ES 0.10), and small for BMIDE, BMIWO, and BMIGA (ES 0.24, 0.47 and 0.24, respectively). The standard error of estimate ranged from 3.85 (BMIJA) to 3.91% (BMIGA). Bland-Altman analysis indicated that the 95% limits of agreement were narrowest for BMIJA (±7.62%) and widest for BMIDE (±8.47%). CONCLUSION: These results highlight the practical usefulness of BMIJA equation in predicting BF% among female young adults when BIA, one of the most ubiquitous field techniques, is not available.
