Methods: Consecutive patients whose BMD had been checked using dual-energy X-ray absorptiometry at Gwangmyung Sungae Hospital were recruited. Patients were divided into two groups according to the presence of type 2 DM. Risk factors of OVCF including age, BMI, current smoking status, current alcohol consumption, and presence of osteoporosis were analyzed separately in the type 2 DM group and control group. Results: A total of 1,130 patients were enrolled in this study. The mean age was 63.2 years. BMI was positively correlated with lumbar BMD in the control group (r =0.284) and in the diabetic group (r =0.302). In subgroup analysis, BMI and age were significant risk factors of OVCF in the type 2 DM group. In multiple linear regression analysis, type 2 DM (β =0.035; 95% confidence interval [CI], 0.005–0.065; p =0.024) and BMI (β =0.015; 95% CI, 0.012–0.018; p <0.001) were positively correlated with lumbar BMD, and age was negatively correlated with BMD (β =−0.006; 95% CI, −0.007 to −0.004; p <0.001). Conclusions BMI was positively correlated with lumbar BMD and was higher in type 2 diabetic patients. Age was negatively correlated with lumbar BMD.
