Precision and accuracy of bioelectrical impedance analysis devices in supine versus standing position with or without retractable handle in Caucasian subjects

BACKGROUND & AIMS Bioelectrical impedance analysis (BIA) could be facilitated in subjects who are able to stand by using scales without (BIAstd4) or with a retractable handle (BIAstd8), provided that they are as precise as BIA devices commonly used in the supine position in the hospital setting (BIAsup). This observational prospective cross-sectional study aimed to compare the precision and accuracy of BIAstd4, BIAstd8 and BIAsup in a Caucasian population. METHODS Fat mass percentage (FM%) was measured in 160 healthy Caucasian subjects (80 men/80 women) aged 20-60 years, with a body mass index (BMI) ≥18.5 and
