The usefulness of the updated bioelectrical impedance vector analysis references for assessing malnutrition, sarcopenia and predicting mortality in hospitalized patients.

Background & Aims: The application of validated pre-screening tools is crucial in clinical practice to identify patients at risk for disease. Bioelectrical Impedance Vector Analysis (BIVA) has gained recognition as a qualitative method for monitoring body composition and assessing the health status of hospitalized patients. This study investigates the utility of updated BIVA reference standards in evaluating malnutrition, sarcopenia, and mortality among hospitalized individuals.
