Body composition measures assessed by bioelectrical impedance analysis and dual-energy X-ray absorptiometry in a sample of Brazilian adults and older adults
Significant discrepancies existed between BIA- and DXA-derived body composition measures in this heterogeneous sample of Brazilian individuals. The developed prediction equations effectively calibrated <sub>BIA</sub>FFM estimates to align with DXA values, providing a practical method to enhance the accuracy of BIA for body composition assessment in this population.
