Abstract: Sarcopenia in children is an emerging concept. Recent researches have shown that sarcopenia also occurs in children. The etiology of sarcopenia in children is complex, primarily due to pathologic factors, but also in a healthy population of children and adolescents, where underactivity and sedentary behavior can lead to reduction in skeletal muscle mass, decline in muscle function, and ultimately, the emergence of sarcopenia. The methods of assessing sarcopenia in children are still not well researched, and are mainly divided into two techniques: functional assessment and body composition analysis. Studies on sarcopenia have so far been conducted mainly in the context of the elderly or chronically ill, and there is a serious lack of research on sarcopenia in children. For the sake of children's healthy development, in-depth research on sarcopenia in children should be strengthened to formulate effective assessment tools and treatment strategies to improve the physical fitness of children in China.

摘要： 儿童肌少症是一个新兴的概念,近几年研究表明,肌少症在儿童期也会出现,其病因十分复杂,主要为病理因素,但在健康的儿童青少年群体中,活动不足、久坐也会导致骨骼肌质量减少、肌肉功能下降,最终出现肌少症。目前为止儿童肌少症评估方法的研究尚不完善,其主要分为功能评估技术和体成分分析技术两种。肌少症主要是在老年人或慢性病患者的背景下进行研究,对于儿童肌少症的研究严重不足。为了儿童的健康发展,应该加强对儿童肌少症的深入研究,制定有效的评估手段和治疗策略,提高我国儿童的身体素质。
