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

Measuring Adiposity in Patients: The Utility of Body Mass Index (BMI), Percent Body Fat, and Leptin

This 2012 cross-sectional study evaluated 1,393 adults (63% female, mean age 51.4 years) to compare BMI, percent body fat (via DXA), and leptin levels in assessing obesity. While BMI identified 26% as obese, DXA revealed 64% were obese, indicating BMI underestimated obesity prevalence. Notably, 39% were misclassified as non-obese by

Sarcopenia: revised European consensus on definition and diagnosis

This 2019 consensus by the European Working Group on Sarcopenia in Older People (EWGSOP2) redefines sarcopenia as a muscle disease characterized primarily by low muscle strength. Diagnosis involves a stepwise approach: (1) identifying probable sarcopenia through low muscle strength; (2) confirming diagnosis by assessing low muscle quantity or quality; and
