The correlation between body fat percentage measured by bio-impedance and corporal circumferences in morbid obese
Abstract
Objective: To relate the results of the percentage of fat analyzed by the method of electrical bioimpedance (BIA) in morbidly obese women with the results obtained from fórmulas that use body circumferences as a reference. Materials and Methods: Twenty-three women (n=23) participated in the study. Two meetings were scheduled for the evaluations, the first of which was the measurement of height and bioimpedance assessment and the second for the measurements of waist, hip, abdominal and neck circumferences. Results: Significant differences were found (p<0.05) in the comparison between the percentage of fat obtained with BIA and the fórmulas of Lean, Weltman and Deurenberg. However, no significant differences were found (p>0.05) when comparing the percentage of fat between BIA and Tran and Weltman fórmulas (p>0.05). Although the correlation between BIA and the fórmulas of Lean (R=-0.26) and Tran and Weltman (R=0.26) is not significant (p>0.05), the present study demonstrated a significant correlation (p<0.05) with the formulas of Weltman (R=0.54) and Deurenberg (R=0.56). Conclusions: There is a significant correlation between the values of the fat percentage of morbidly obese individuals obtained by BIA with traditional methods that involve measures of body circumference.
