Abstract

Sarcopenia, a well-known geriatric syndrome, is defined as the age-related loss of muscle mass plus declined muscle function (muscle strength and/or physical performance). Sarcopenia is associated with a number of adverse outcomes, including poor quality of life, falls, disability, and mortality. The clinical impact of sarcopenia on older people will escalate along with the rapid growth of elderly population in Asia. Moreover, the differences of ethnic backgrounds between Asian people and Westerners have trigger the need for specific diagnostic criteria for Asian populations. After the publication of Asian Working Group for Sarcopenia consensus, sarcopenia has gained even more extensive research attention in Asia. In general, the reported prevalence of sarcopenia in Asia was lower than Western countries, ranging from 2.5% to 45.7%. Asian people tend to have lower muscle mass, weaker grip strength, slower gait speed, and higher body fat mass with central distribution. Compared to Western populations, the rate of age-related muscle mass decline in older Asian people remain relatively unchanged, but the decline rate in muscle strength or physical performance was more significant along with aging. With aging, Asian people presented with greater increase in fat mass and higher prevalence of central obesity, especially in women. Due to the great impact of sarcopenia, a life course program for good nutrition and physical activities would be of great benefit. However, various research challenges remain to be resolved in the future and more outcome-based trials are needed to formulate the most optimal strategy for sarcopenia in Asia.

亚洲人群少肌症的性别差异:诊断和治疗意义
Sarcopenia是一种众所周知的老年综合征,被定义为与年龄相关的肌肉质量损失加上肌肉功能(肌肉力量和/或身体表现)下降。Sarcopenia与许多不良后果有关,包括生活质量差、跌倒、残疾和死亡率。随着亚洲老年人口的快速增长,少肌症对老年人的临床影响将加剧。此外,亚洲人和西方人之间的种族背景差异引发了对亚洲人群特定诊断标准的需求。亚洲少肌症工作组共识发表后,少肌症在亚洲得到了更广泛的研究关注。总的来说,据报道,亚洲少肌症的患病率低于西方国家,从2.5%到45.7%不等。亚洲人的肌肉质量往往较低,握力较弱,步态较慢,体脂质量较高,呈中心分布。与西方人群相比,亚洲老年人与年龄相关的肌肉质量下降率保持相对不变,但随着年龄的增长,肌肉力量或身体表现的下降率更为显著。随着年龄的增长,亚洲人的脂肪量增加幅度更大,中心性肥胖的患病率更高,尤其是女性。由于少肌症的影响很大,一个良好营养和体育活动的生命课程计划将大有裨益。然而,未来仍有各种研究挑战有待解决,需要更多基于结果的试验来制定亚洲少肌症的最佳策略。
