Comparison of Three Prediction Equation of Body Fat Percentage via Skinfold Thickness Method with Segmental Multi-Frequency Bioimpedance in Caucasian Area Adolescent Boys

English Abstract

Body composition is frequently used as one of several indicators of overall health fitness. Accurate measurements of the body composition in young boys are essential to evaluate nutritional status and health implications. This study was conducted to compare 3 equations Brozek , Slaghter and Jackson-pollock, in prediction of Body Fat percentage (%BF) via Skinfold thickness (SKF) method with Segmental Multi-Frequency Bioimpedance (SMFBIA) as a criterion method, in 15-17 years-old Azerbaijan-Iranian adolescent boys. Subjects were 45 healthy boys whose mean±SD age, height, weight and BMI were 16.04±0.767 years, 168±7.73 cm, 59.6±9.77 kg, 20.69±3.19 kg m<SUP>-2</SUP>, respectively. %BF values were calculated using three selected equation and SMFBIA (inbody 3). Methodological differences among the these methods (three selected equation and BIA) were analyzed with Bland-Altman (1986) method. The value mean±SD of %BF were obtained using the SMFBIA method (12.45±6.15%). Results showed that predicted %BF by brozek-lohman equation has highest agreement with SMFBIA method (mean±SD difference,(-0.99±1.25%, p< 0.05). Slaghter equation overestimated %BF comparison with SMFBIA (5%, p< 0.05) and Jackson-pollock equation underestimated %BF comparing with SMFBIA (-5.46%, p< 0.05). This study demonstrates that; although all equations used in present study have been commonly utilized to estimate body fat percentage in world adolescent boys, but the brozek-lohman equation hold promise for estimating (%BF) in Azerbaijan -Iranian adolescent boys. Obviously it is necessary to do further studies.
