A Comparative and Sex-Specific Study of Bio-Electrical Impedance Analysis and Dual Energy X-ray Absorptiometry for Estimating Whole-Body and Segmental Body Composition in Healthy Young Adults

Bio-electrical impedance analysis (BIA) and dual-energy X-ray absorptiometry (DXA) are methods to estimate human body composition. This study aimed compare sex-specific outcomes for estimating segmental whole-body composition in 83 healthy participants (21.9 ± 1.5 years, 56% men) using Inbody S10 BIA Norland Elite DXA devices. One-way repeated measures ANOVAs showed significantly lower fat% fat mass values alongside higher lean resulting from when compared (both sexes: p < 0.001). In men, bone mineral content was against (p Regardless of sex, no significant versus difference found arm (men: = 0.180, women: 0.233), whereas leg were with Additionally, 0.001) (only DXA. Moderate very strong positive associations 0.05) between outcome found, except 0.904, 0.130) men: 0.845). highlights (sex-dependent) differences corresponding test both at the level.
