老年肌少症及其合并症的营养干预研究进展

Research progress on nutritional intervention in elderly sarcopenias and its complications

肌少症又称“少肌症”“肌肉减少症”“肌肉衰减症”,是一种以与年龄相关的肌肉质量下降、肌肉力量和功能衰退为主要特点的老年综合征,其可增加患者身体残疾、生活质量差和死亡等不良后果风险。肌少症的发病因素主要包括高龄、疾病、缺乏运动、营养不良等,而机体营养状况作为影响肌少症的关键因素之一,在肌少症发生发展中起重要作用。本文就营养在肌少症中的作用,以及常见慢性疾病合并肌少症患者的营养干预进行综述,旨在为老年肌少症患者制定更加科学、合理的营养干预方案提供依据。

Sarcopenia,also known as"oligomyositis""hypomyositis"and"muscle wasting",is an age-related geriatric syndrome characterized by decreased muscle mass,muscle strength and function decline.It can increase the risk of adverse outcomes such as physical disability,poor quality of life,and death.The pathogenic factors of sarcopenia mainly include older age,diseases,lack of exercise,malnutrition,etc.As one of the key factors affecting sarcopenia,the nutritional status of the body play an important role in the development of sarcopenia.Therefore,this paper reviews the role of nutrition in sarcopenia and nutritional interventions for patients with common chronic diseases combined with sarcopenia,aiming to provide a basis for the developing more scientific and rationalized nutritional intervention program for elderly patients with sarcopenia.
