Body fat assessment of young Syrian adults using bioelectrical impedance analysis and deuterium dilution

Al-Bachir Mahfouz, . and Othman Ibrahim, . Body fat assessment of young Syrian adults using bioelectrical impedance analysis and deuterium dilution. pp. 173-182. ISSN 1394-035X

Introduction: The purpose of this study was to compare body composition assessed by bioimpedance analysis (BIA) against deuterium dilution (D2 O) techniques. Methods: This study was conducted on 215 young Syrian adults. Total body water (TBW) fat free mass (FFM) and fat mass (FM) compartments were calculated from the measurements of resistance made at 50 kHZ using the formula provided by the instrument manufacturer (Bodystat) and D2 O equation. Bland-Altman plot analysis was used to compare methods and linear regression analysis were performed to detect the relation between the variables (R2 0.81). Results: Percentage of body fat derived from BIA (16.2 7.3) and and D‚‚O technique (21.326.42) were significantly different (p0.001). BIA body composition assessments provided good relative agreement with the selected criterion method of and D‚‚O as indicated by high correlation coefficients (r0.91). Conclusion: When compared with and D‚‚O BIA overestimated TBW and FFM and underestimatd FM (P0.001) in young adults (-5.2; -3.4 kg).
