Bio-electrical impedance vector analysis: testing Piccoli’s model against objective body composition data in children and adolescents

摘要

Background/ObjectivesBio-electrical impedance (BI) analysis is a simple body composition method ideal for children. However, its utility in sick or malnourished children is complicated by variability in hydration. BI vector analysis (BIVA) potentially resolves this, using a theoretical model that differentiates hydration from cell mass. We tested this model against reference methods in healthy children varying widely in age and nutritional status.
