Comparisono of the Effectiveness of Dual Energy X-Ray Absorptiometry, Ultrasound Bone Densitometry and Bioelectrical Impedance Analysis in Assessing of Bone Mass

We investigated whether the assessment of bone density using the comparatively convenient and portable ultrasound bone densitometry and bioelectrical impedance analyzer, which do not involve radiation, could substitute for the dual energy X -ray absorptiometry (DXA). Bone mineral content (BMC) and bone mineral density (BMD) in the entire skeleton and BMD in the lumbar vertebrae were measured using DXA and trabecula bone area ratio in the calcaneus was measured using ultrasound bone densitometer with quantitative ultrasound method (QUS). Moreover, body height, weight, somatic fat volume and bone mass were measured using bioelectrical impedance analysis (BIA). DXA measurement of the lumbar vertebrae, calcaneal BAR using QUS and BMC using BIA were carried out in 1,073 adults, and DXA measurement of the lumbar vertebrae and that of the entire skeleton in 1,356 adults. So, we found statistically that there were well correlation between whole settings, measurement of bone content or density frebody BMC and BMD, lumbar BMD and whole body BMD and BMC, lumbar BMD and BMC using BIA, lumbar BMD and calcaneal BAR, respectively.
