[The assessment of bone quality in lifestyle-related diseases].

Abstract Type 2 diabetes mellitus(DM)and other lifestyle-related diseases are associated with an increased risk of bone quality deterioration-type osteoporosis. The deterioration of bone quality in type 2 DM involves factors such as qualitative changes of collagens, reduction in bone turnover, narrow cortical bone diameter, increased cortical bone porosity, and destruction of trabecular bone microarchitecture. In mild to moderate chronic kidney disease and chronic obstructive pulmonary disease, the factors involved are thought to be hyperhomocysteinemia and deterioration of trabecular bone microarchitecture as well as cortical bone structure. Investigations of the usefulness of bone quality assessment using approaches such as the following are under way:biocheminal markers such as pentosidine and homocysteine, bone structure assessment methods such as hip structure analysis, trabecular bone score, and high-resolution peripheral quantitative computed tomography.
