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
