Prediction of fat-free mass in a multi-ethnic cohort of infants using bioelectrical impedance: Validation against the PEA POD

Frontiers in Nutrition, 2022
BackgroundBioelectrical impedance analysis (BIA) is widely used to measure body composition but has not been adequately evaluated in infancy. Prior studies have largely been of poor quality, and few included healthy term-born offspring, so it is unclear ...

Low-cost and portable impedance plethysmography system for the simultaneous detection of respiratory and heart activities [PDF]

, 2019
Impedance plethysmography is a technique that allows monitoring changes in the volume of specific tissues or organs inside the human body, through the measurement of variations in the bio-impedance between electrodes placed on the body surface.

Body fat measurement by bioelectrical impedance and air displacement plethysmography: a cross-validation study to design bioelectrical impedance equations in Mexican adults

Nutrition Journal, 2007
Background The study of body composition in specific populations by techniques such as bio-impedance analysis (BIA) requires validation based on standard reference methods. The aim of this study was to develop and cross-validate a predictive equation for
