Bia is currently used in diverse settings including private clinicians offices health clubs and hospitals and across a spectrum of ages body weights and disease states. It is an integral part of a health and nutrition assessment. The technology is relatively simple quick and noninvasive.
Bioelectrical impedance analysis bia is a commonly used method for estimating body composition in particular body fat and muscle massin bia a weak electric current flows through the body and the voltage is measured in order to calculate impedance resistance of the body. Comparison of agreement between the methods. 2018 practical measurement of body composition using bioelectrical impedance air displacement plethysmography and ultrasound in stable outpatients with short bowel syndrome receiving home parenteral nutrition. Participants were a non federal nonadvocate 13 member panel representing the fields of nutrition pediatrics surgery public health biomedical engineering epidemiology and biostatistics. Bioelectrical impedance analysis bia is a widely used method for estimating body composition. Fat muscle water and other important indicators of underlying medical conditions are not considered in the bmi.
The measurement of body fat in relation to lean body mass. Bioelectrical impedance analysis bia and body composition analyse as a physician you know that the body mass index bmi by itself is no t sufficient to analyze a patients health status and body composition thoroughly. Most body water is stored in muscle. The objective of this conference was to provide physicians with a responsible assessment of bioelectrical impedance analysis bia technology for body composition measurement.
