The objective of this study was to determine the accuracy of three kind of bioelectrical impedance analysis (BIA) to assess body composition (BC) in overweight and obese adults. Fifty-three healthy obese people (ages 26 to 75 years; BMI, 25 to 32 ㎏/㎡) underwent BIA assessment of BC using the hand-foot BIA (Zeus) (H-F<SUB>IMP</SUB>) and handhand BIA (Omron 305) (H-HIMP) and the foot-foot BIA (Tanita 611) (F-FIMP). Measures of validity were determined by Pearson correlations between BIA and DXA, paired t-tests to assess mean differences, as well as biases and limits of agreement. All BIA methods showed good relative agreement with DXA [H-F<SUB>IMP</SUB>: fat mass (FM), r²=0.81; fat-free mass (FFM), r²=0.81; percentage body fat (BF%), r²=0.69; H-H<SUB>IMP</SUB>: FFM, r²=0.76; BF%, r²=0.40; F-F<SUB>IMP</SUB>: FFM, r²=0.79, BF%, r²=0.44; all p<0.001]. Absolute agreement between DXA and H-H<SUB>IMP</SUB> was moderately good, as indicated by a small bias and wide limits of agreement (bias, +/?1.96 standard deviation; FFM, 1.0, +/?4.9 ㎏; BF%, ?1.3, +/?7.5%). H-F<SUB>IMP</SUB>: and F-F<SUB>IMP</SUB> also exhibited a smaller bias but wide limits of agreement (H-F<SUB>IMP</SUB>: FFM, 0.7, +/?5.3 ㎏; BF%, ?0.9, +/?6.9%; F-F<SUB>IMP</SUB>: FFM, 0.3, +/?5.7 ㎏; BF%, 00.5, +/?7.8%). Compared with DXA, H-H<SUB>IMP</SUB> produced large bias and wide limits of agreement, and its accuracy estimating body composition in obese men was poor. H-F<SUB>IMP</SUB> and F-F<SUB>IMP</SUB> demonstrated little bias and may be useful for group comparisons, but their utility for assessment of body composition in individuals is limited.
