Abstract:
Objective To explore the possible risk factors that influence bone mineral density (BMD) in elderly men with type 2 diabetes. Methods A total of 80 elderly men with type 2 diabetes were included in this study. The BMD of lumbar vertebrae and femur were measured by dual-energy X-ray absorptiometry (DXA). And fasting blood and urine samples were taken to check the biochemical levels of bone metabolism and blood glucose. The correlations between BMD and other related factors were analyzed. Results In this group, the prevalence rates of osteoporosis and osteopenia were 18. 6% and 53.8%, respectively. Body mass and body mass index (BMI) were positively correlated with BMD at all sites (r=0. 202～0. 298, P<0. 05 or P<0. 01). However, age and glycosylated hemoglobin (HbAlc) were negatively correlated with BMD of lumbar and femoral neck (r=-0. 172～-0. 211 ,all P<0. 05). Leptin was not only positively correlated with the BMD of femoral neck and Ward's triangle, but also with body mass, BMI, fasting blood glucose (FBG), total cholesterol and HbAlc (r=0. 219 ～ 0. 509, P<0.05 or P<0.01). Using stepwise regression analysis, body mass was the predictor of BMD at all sites assessed, while the HbAlc and leptin levels could respectively influence BMD at femoral neck and Ward's triangle (r~2= 0. 196 ～ 0. 276, all P< 0. 01). Conclusions It may suggest that differential factors predict the variance of BMD at different sites in elderly men with type 2 diabetes.
