肌肉减少症是一种以骨骼肌力量、含量、质量以及功能下降为主要特征的进行性骨骼肌疾病,好发于老年人、肿瘤 患者及各类慢性病患者。 肌肉减少症显著增加高风险人群的跌倒风险、手术并发症发生率和死亡率,给医疗及社会带来沉重 的负担。 然而,目前肌肉减少症的筛查、诊断标准尚未统一,仍缺乏适合中国人群的系统性和个体化的诊断标准和治疗措施 规范。 本文旨在通过对已发表的肌肉减少症相关研究及指南进行总结,建立具有我国特色的规范化的肌肉减少症筛查标准、 诊断与治疗的流程及体系,适用于我国各级医疗机构开展肌肉减少症的筛查、评估、诊断、治疗与监测,为临床工作人员和研 究者提供参考。

Sarcopenia is a progressive skeletal muscle disease characterized by a decline in muscle strength quantity quality and function. It is commonly observed in elderly individuals cancer patients and those with chronic diseases. Sarcopenia significantly increases the risk of falls surgical complications and mortality rates among high-risk populations imposing a substantial burden on both healthcare systems and society. However there is currently no unified screening and diagnostic criteria for sarcopenia and there is a lack of systematic and individualized diagnostic criteria and standardized treatment measures suitable for the Chinese population. This article aims to summarize published research and guidelines related to sarcopenia to establish standardized screening criteria diagnostic and treatment processes and systems with Chinese characteristics. These can be applied in healthcare institutions at all levels in China for screening assessment diagnosis treatment and monitoring of sarcopenia providing a reference for clinical practitioners and researchers.
