Generation of Prediction Equations to Analyze Body Composition of the Elderly Based on Bioelectrical Impedance Analysis (BIA)
In Brief
An observational study for Healthy Elderly. Completed, enrolled 150 participants across 1 site.
Detailed Summary
The objective of the study is to develop prediction equations for calculating Fat-Free Mass FFM, Total Body Water TBW, Extracellular Water ECW, Visceral Adipose Tissue VAT, total Skeletal Muscle Mass SMM and segmental SMM in a group of elderly. The prediction equations are based on linear regression analysis between the gold standard reference methods Air Displacement Plethysmography ADP, Dual-energy X-ray Absorptiometry DXA, Magnet Resonance Imaging MRI, Deuterium dilution method (D2O) and Sodium Bromide dilution method (NaBr) on the one hand and bioelectrical impedance measurements on the other hand. Multi-frequency bioimpedance is measured for all body segments: right arm, left arm, right leg, left leg, trunk, right body side and left body side using the seca mBCA 515 in standing position and the seca mBCA 525 in standing and lying position.
