摘要: Objective: To compare the accuracy of percentage body fat (%BF) estimates between bioelectrical impedance analysis (BIA) and DXA in obese African-American women. Research Methods Procedures: Fifty-five women (mean age, 45 years; mean BMI, 38; %BF, 48%) were studied. BF was assessed by both BIA (RJL Systems 101Q; RJL Systems, Clinton Township, MI) (Hologic QDR-2000 Bone Densitometer; Hologic Inc., Bedford, MA). Generalized ethnicity- obese-specific equations used to calculate %BF from BIA. Bland-Altman analyses agreement DXA, with serving as criterion measure. Results: Two generalized provided consistent across weight range comparison estimates, whereas most other increasingly underestimated increased. One one ethnicity-specific had differences that not significantly different value. Discussion: The findings show Lukaski equation precise accurate QDR 2000 provide preliminary support for use this women.
