Analysis of variation of BMD in patients with type 2 diabetes mellitus

Objective To invesity the changes of bone mineral density (BMD) in patients with type 2 diabetes mellitus.Methods Dural energy x-ray absorptimetry was used to measure the BMD of lumbar spines (L 2-4 ) and proximal femur in 173 patients with type 2 diabetes mellitus and 101 cases of normal control. Results (1) The BMD of lumbar spines (L 2-4 ) and proximal femur in male patients with type 2 diabetes in the group that is over 65 years was significant lower than that of the control group (P0.01,P0.05). There was obvious difference of the BMD of lumbar spines (L 2-4 ) and Ward's triangle between 55-65 year group and the control group with the same age. (2) The BMD of lumbar spines (L 2-4 ), femoral neck and Ward's triangle in female patients with type 2 diabetes mellitus in over 55 years of age was significant lower than that of the control group with the same age (P 0.01 ,P0.05).Conclusions (1) The changes in BMD of above areas in type 2 diabetes mellitus are different. (2) The BMD of lumbar spines (L 2-4 ) and Ward's triangle in diabetic patients in over 55 years of age was significant lower than that of the control group.
