2型糖尿病女性患者髋部骨折与骨密度危险阈值的相关性

目的 探讨女性糖尿病髋部骨折与骨密度危险阈值.方法 L unari双能X线吸收仪测量女性2型糖尿病髋部骨折患者健侧股骨颈,Wards三角区及大转子的BMD值,并与同期非骨折的女性2型糖尿病相比较.比较2组患者的年龄、绝经年限、糖尿病病程和骨密度等因素差异,采用受试者工作曲线ROC分析BMD值与髋部骨折的关系.结果 骨密度值与年龄呈负相关,随着年龄增大骨密度呈下降趋势;骨折组与对照组在不同部位的BMD值相比,BMD值差异有统计学意义（P＜0.01）.Ward三角的骨密度值为骨折易发生的BMD阈值,女性糖尿病患者为0.556 g/cm^2.结论 检测老年女性2型糖尿病患者的骨密度可预测髋部骨折.

The Corelation between Hip Fracture and Bone Mineral Density Dangerous Threshold in Fernal Patients with Type2 Deabetes

Objective To investigate the correlation hip fracture and bone mineral density risk threshold Methods Lunari dual-energy X-ray absorptiometry measurement of hip fracture the contralateral femoral neck,and Ward＇ triangle and big rotor BMD values,and with the same period of fractures in women compared with type 2 diabetes.Risk factors such as age,postmenopausal time,course of type 2 diabetes and BMD were compared.The value of BMD for predicting the hip fracture was analyzed by receiver operating characteristic curve （ROC） and regression analyis.Results Negative correlation was found between the BMD values and age.There was significant difference in BMD between the study and control group of female patients with type 2 diabetes （P＜ 0.01）.The Ward triangle BMD values at 0.556g/cm^2 was determined the fracture threshold for females of type 2 diabetes.Conclusion Bone density test can predict the incidence of hip fracture in elderly women patients with type 2 diabetes mellitus
