DXA-based variables and osteoporotic fractures in Lebanese postmenopausal women

Abstract

Epidemiological study, level IV.

Positive Correlations Between Free Vitamin D and Bone Variables in a Group of Young Lebanese Men

“…Bone strength is not only influenced by bone mineral density (BMD) but also by bone geometry (13). Several DXA-based variables other than BMD can predict fracture risk in elderly subjects such as bone mineral apparent density (BMAD), crosssectional area (CSA) of the femoral neck, compressive strength index (CSI), bending strength index (BSI), impact strength index (ISI) and trabecular bone score (TBS) (14,15). In order to maintain healthy bones, adequate serum vitamin D levels should be maintained (16).…”

“…Composite indices of FN strength were calculated as previously described (14,15). FN compressive strength index (CSI), FN bending strength index (BSI), and FN impact strength index (ISI) were calculated (14,15). Compressive strength ( ) and bending strength ( ) express the forces that the FN has to withstand in weight-bearing, whereas impact strength (…”

“…) expresses the energy that the FN has to absorb in an impact from standing height (14,15). Free vitamin D, vitamin D binding protein and total vitamin D were measured as previously described (22).…”
