Comparison of multi- and single-frequency bioelectrical impedance analysis with dual energy x-ray absorptiometry for assessment of body composition in postmenopausal women: Effects of body mass index and accelerometer-determined physical activity

Popis výsledku v původním jazyce

Bioelectric impedance analysis (BIA) is commonly used in research to assess body composition. However, studies that validate the accuracy of BIA exclusively in postmenopausal women are lacking. The main purpose of this study was to evaluate the agreementof multi- (MF-BIA) and single- (SF-BIA) frequency BIA with dual energy x-ray absorptiometry (DXA) in the estimation of fat mass (FM) and fat-free mas (FFM) among postmenopausal women with various body mass indexes (BMI) and physical activity (PA). FM and FFM were estimated by BIA and DXA in 146 postmenopausal women with mean age 62.8 +- 5.2 y. PA was determined by an accelerometer. The mean difference between MF-BIA and DXA was -1.8 +- 1.8 kg (P = 0.08) and 1.3 +- 1.8 kg (P = 0.01) for FM and FFM, respectively. SF-BIA provided a significantly lower estimate of FM (-2.0 +- 2.2 kg; P = 0.04) and a higher estimate of FFM (1.8 +- 2.4 kg; P < 0.01) compared with DXA. MF-BIA provided significantly better estimates of FM and FFM with narrower
