Results
All parameters matched for age,
height and weight.
Spinal DXA BMC and BMD were strongly and positively correlated with pQCT SSI at both radii and right tibia and weakly associated with pQCT cortical density at both radii and tibiae.
Whole body DXA BMC was strongly correlated with strength at the left tibia and moderately at the right and weakly associated with pQCT total density of both hands.
Both spinal and wholly body DXA BMC and BMD and height were strongly correlated with pQCT cortical content,
area and thickness at both tibiae and trabecular content at the right tibia and moderately associated with Tanner stage and trabecular content at the left hand and lower legs.
Pearson correlation coeficient was used to estimate the relationship between pQCT and DXA parameters.
