摘要：

衰弱是老年人的一种常见综合征，其核心特征是多种生理系统(神经肌肉系统、内分泌系统、免疫系统等)储备功能下降，表现为机体易感性增加，稳态下降。这类老年人常伴有一些慢性非致命性疾病。糖尿病是老年人最常见的慢性病之一。急慢性并发症引起的残疾和过早死亡严重影响患者的生存时间和生活质量。此外，中国是世界上糖尿病患者数量最多的国家。其中2型糖尿病占90.0%以上，60岁以上老年人2型糖尿病患病率占20%以上。随着年龄的增长和疾病的进展，一方面老年糖尿病患者会出现肌肉的丧失以及耐力、运动能力和平衡能力的损伤。另一方面，它们往往处于多种疾病并存的状态。一项关于衰弱与糖尿病患者不良结局之间关系的系统综述表明，衰弱可增加老年糖尿病患者的不良结局，如跌倒、住院和死亡。早期有效的干预可防止或延迟衰弱的过程。 Thereby, it can also reduce the adverse clinical outcomes of them. International researchers have paid attention to the monitoring and evaluation of the debilitation patients, and conducted a large number of investigations on the problem of diabetes mellitus combined with debilitation. The incidence of debilitation in diabetic patients ranged from 28.8% to 60.9%. According to the systematic search literature analysis, it is found that there are few reports on the weakening of the domestic focus on senile diabetes, which is still in its infancy. In view of this, it is necessary to understand and explore the debilitating status and influencing factors of elderly patients with type 2 diabetes in China, and provide reference and basis for further targeted intervention in the debilitation of elderly patients with type 2 diabetes.
