Bone mineral density analysis in type 2 diabetes retinopathy
Objective: To investigate the changes of bone mineral density in patients with type 2 diabetic retinopathy. Methods: A total of 111 patients with type 2 diabetes were selected. They were divided into two groups, retinopathy group, non- retinopathy group. Triglycerides, total cholesterol, high-density lipoprotein cholesterol, low density lipoprotein cholesterol, blood uric acid was measured by automatic biochemical detector. Bone mineral density was measured by the United States-36 dual-energy X-ray absorptiometry (dexa) which is from Norland XR Company. Asessed the BMD of lumbar vertebrae 1-4 and the left side of the femoral neck, greater trochanter and Ward’s triangle. Results: 1) The femoral neck of diabetic patients with retinopathy, greater trochanter and Ward's triangle compared with diabetic patients with non-retinopathy, the BMD of the former is lower the later, the difference was statistically significant (P<0.05). There was no statistically significant difference in the lumbar spine (P>0.05); 2) The BMD was positively correlated with BMI, uric acid. And negatively correlated with age, duration, blood lipids in type 2 diabetes. Conclusion: In patients with type 2 diabetic retinopathy the bone mineral density is decrease.
