Cross-calibration of Eight-Polar Bioelectrical Impedance Analysis Versus Dual-Energy X-Ray Absorptiometry for the Assessment of Total and Appendicular Body Composition in Healthy Subjects Aged 21–82 Years

This 2003 cross-sectional study assessed the validity of eight-polar bioelectrical impedance analysis (BIA) compared to dual-energy X-ray absorptiometry (DXA) in 110 healthy adults aged 21–82 years. The resistance index (RI), calculated as height² divided by resistance at 500 kHz, emerged as the strongest predictor of fat-free mass (FFM) and appendicular

Validity of Segmental Multiple-Frequency Bioelectrical Impedance Analysis to Estimate Body Composition of Adults Across a Range of Body Mass Indexes

This 2009 cross-sectional study assessed the accuracy of eight-electrode segmental multiple-frequency bioelectrical impedance analysis (MF-BIA) in estimating body composition compared to dual-energy X-ray absorptiometry (DXA) in 132 healthy adults categorized as normal weight (BMI 18.5–24.9), overweight (BMI 25–29.9), and obese (BMI 30–39.9). MF-BIA overestimated body fat percentage (%BF) in obese
