Therefore if a person is more muscular there is a high chance that the person will also have more body water which leads to lower impedance. National institutes of health technology assessment conference statement.

Bioelectrical impedance analysis in body composition measurement. Bioelectrical impedance analysis bia estimates body composition using equations that calculate the difference of electrical conductivity among different tissues eg bones adipose muscle cartilage 17. 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. Participants were a non federal nonadvocate 13 member panel representing the fields of nutrition pediatrics surgery public health biomedical engineering epidemiology and biostatistics. Muscle fat bone etc all have varying amounts of water content and as a result they all differ in terms of electrical conductivity. In addition 20 experts. 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.
The technology is relatively simple quick and noninvasive. To provide physicians with a responsible assessment of bioelectrical impedance analysis bia technology for body composition measurement. Bioelectrical impedance analysis is a commonly used method for estimating body composition in particular body fat and muscle mass. Most body water is stored in muscle. Bioelectrical impedance analysis bia is a relatively simple quick and non invasive technique to measure body composition. Impedance tissue resistance and reactance is registered when a lowvoltage current is passed through the body 18.
It measures body fat accurately in controlled clinical conditions but its performance in the field is inconsistent. Bioelectrical impedance analysis in body composition measurement. No authors listed objective. Bioelectrical impedance analysis bia is able to make an estimation of body composition eg. Assessment of bioelectrical impedance analysis bia technology for body composition measurement. Bioelectrical impedance analysis bia is a safe and cost efficient method that avoids exposure to radiation and is used to measure body composition.
Since the advent of the first commercially available devices. Quantities of fat mass and fat free mass by running a small electrical current through the body. The present study aimed to determine the agreement and feasibility of three methods bioelectrical impedance analysis bia ultrasound and air displacement plethysmography adp for measuring body composition in people receiving hpn. This is possible simply because different bodily tissues eg. It is based on the difference in resistance when an electrical current is conducted through fat or lean components of the body. Bioelectrical impedance analysis bia is a widely used method for estimating body composition.
In bia a weak electric current flows through the body and the voltage is measured in order to calculate impedance of the body. Fat muscle water and other important indicators of underlying medical conditions are not considered in the bmi.
