Correlation of Bioelectrical Impendance Analysis and Dual Energy X-ray Absorptiometry for Bone Mineral Content and Bone Mineral density in young healthy humans

Introduction: Bioelectrical impendance analysis (BIA) and dual energy X-ray absorptiometry (DXA) are two most common methods used for body composition analysis. The aim of this study was to investigate correlations of: A)body mineral content (BMC) determined by BIA and by DXA, and B) results of BIA (BMC) and DXA (BMD)at lumbar spine and hips. Methods: 27 healthy men and women (age 19-23 years) were examined by BIA and DXA. Results: A)Correlation was found between BMC obtained by two methods at all sites. Analyzed by sex ; for male subjects (n=13) only correlation of BMC between BIA and DXA for L1-L4 spine existed ( r=0, 615, p=0, 044), while for females (n=14) correlation was obtained at all sites ; for L1-L4 spine r=0, 739 (p=0, 003), for dual femur total mean r=0, 726 (p=0, 003), and for neck mean r=0, 785 (p=0, 003). B) Correlation between BMC (BIA) and BMD (DXA) was obtained only at dual femur total mean (r=0, 4738, p=0, 0167), when all examinees were included. For male subjects there was no correlation at any site, while for females correlation was found at dual femur total mean (r=0, 726, p=0, 003), and at neck mean (r=0, 709, p=0, 005). Conclusion: BMC vs. BMD showed correlation only in female subjects. Both methods can reliably determine the BMC.
