Abstract: To approach the correlation between the bone density measured by quantitative CT and the blood sugar level of the aged patients with non-insulin-dependent diabetes mellitus，and observe the effects of the blood sugar level on the bone density.Methods The lumbar bone densities and the blood sugar levels of 160 aged patients with non-insulin-dependent diabetes mellitus (hyperglycemia group 80 cases,euglycemia group 80 cases ) and the healthy aged people (80 cases) were detected by quantitative CT and serum biochemical detection; the correlation between the blood sugar level and the bone density and the osteoporosis occurrence status of aged people in various groups were analyzed.Results The bone density in the non-insulin-dependent diabetes and hyperglycemia group was lower than those in normal(control) group and non-insulin-dependent diabetes and euglycemia group (P<0.05); the morbility of osteoporosis in the non-insulin-dependent diabetes and hyperglycemia group was higher than those in normal(control) group and non-insulin-dependent diabetes and euglycemia group (P<0.05);negative correlation was found between the bone density and the blood sugar level (aged male group：r=－0.7382，P=0.0013；aged female group：r=－0.8343，P=0.0007).Conclusion The blood sugar level affects the bone density of the aged patients with non-insulin-dependent diabetes mellitus;the higher the blood sugar level,the lower the bone density.The non-insulin-dependent diabetes aged patients with hyperglycemia have the liability of osteoporosis.
