目的:探究老年2型糖尿病患者肌量减少与动脉粥样硬化的相关性。方法:选择年龄≥60岁的2型糖尿病患者322例，根据四肢骨骼肌指数(ASMI)分为肌量减少组(152例)与非肌量减少组(170例)。入组对象均进行体格检查、双能X线骨密度仪检查、颈部及下肢动脉超声检查、实验室检查。结果:在纳入的322例患者中，合并肌少症49例，患病率为15.22%；合并肌量减少152例，患病率为47.2%。肌量减少组的体重指数(BMI)、T值(T-score)、ASMI、尿酸、稳态模型评估的胰岛素抵抗指数(HOMA-IR)显著低于非肌量减少组(均n P<0.05)。肌量减少组的颈动脉粥样硬化分级、下肢动脉粥样硬化分级均显著高于非肌量减少组(n P<0.05)。多因素n logistic回归分析显示，颈动脉粥样硬化、下肢动脉粥样硬化是肌肉量减少的危险因素，BMI、25-羟维生素Dn 3是肌肉量减少的保护因素。老年2型糖尿病患者颈动脉与下肢动脉粥样硬化分级具有一致性(n P<0.01)。n 结论:动脉粥样硬化对老年2型糖尿病患者早期肌少症具有预测价值。“,”Objective:To investigate the association of muscle mass loss with atherosclerosis in elderly patients with type 2 diabetes mellitus(T2DM).Methods:A total of 322 patients with T2DM aged≥60 years old were divided into muscle mass loss group(n n=152) and non-muscle mass loss group(n n=170) according to their appendicular skeletal muscle mass index(ASMI). All participants underwent physical examination, dual-energy X-ray absorptiometry check, carotid and lower extremity ultrasound, as well as laboratory tests.n Results:Among 322 patients, 49(15.22%) patients were suffered from sarcopenia and 152(47.2%) patients with reduced muscle mass. The carotid and lower extremity atherosclerosis grades in the muscle mass loss group were significantly higher than those in the non-muscle mass loss group(n P<0.05), with lower body mass index(BMI), T-score, ASMI, uric acid, and homeostasis model assessment of insulin resistance index(n P<0.05). Multivariate logistic regression analysis showed that carotid atherosclerosis and lower extremity atherosclerosis were risk factors for muscle mass loss while BMI and 25-(OH)Dn 3 were protective factors for muscle mass loss. There existed a consistency in carotid atherosclerosis grade and lower extremity atherosclerosis grade of elderly patients with T2DM(n P<0.01).n Conclusion:Atherosclerosis has a predictive value for early sarcopenia in elderly patients with T2DM.
