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.
