目的:研究老年2型糖尿病(T2DM)骨密度(BMD)的分布特点。方法:用DXA DAS 600EX型骨密度仪对146例老年患者进行腰椎椎体侧位BMD检测。结果:T2DM组与其他疾病组患者骨质疏松(OP)的患病率分别为76.92%和31.4%,两组差异显著(p<0.001);累及骨丢失率(ABLR)比较:T2DM组和其他疾病组ABLR差异显著(p<0.001);相关关系显示:T2DM组和其他疾病组患者的体重变化与BMD呈正相关(p<0.001),T2DM组患者年龄变化与BMD呈正相关(p<0.001)。结论:该组人群中老年T2DM患者的OP患病率明显高于其他疾病组患者,而且前者的T值及ABLR的下降幅度明显大于后者;老年T2DM组患者随增龄和体重增加,其BMD降低加重。
Objective: To study the distribution of bone mineral density (BMD) in elderly type 2 diabetes mellitus (T2DM). Methods: The BMD of lumbar vertebral body was measured in 146 elderly patients by DXA DAS 600EX bone densitometer. Results: The prevalence of osteoporosis (OP) in patients with T2DM and other disease groups was 76.92% and 31.4%, respectively, with significant difference between the two groups (p <0.001). Compared with the rate of bone loss (ABLR) There were significant differences in ABLR between disease groups (p <0.001). Correlation analysis showed that body weight changes in T2DM and other disease groups were positively correlated with BMD (p <0.001) and age in T2DM patients was positively correlated with BMD (p <0.001). CONCLUSIONS: The prevalence of OP in elderly patients with T2DM is significantly higher than that in other disease groups, and the T value and the ABLR decline rate in the former group are significantly greater than those in the latter. The elderly patients with T2DM group have higher BMD Reduce the increase.
