随着年龄的增加,人们往往会出现四肢变细,肌肉变软,觉得腿脚没劲,力量变差,走路速度变慢等现象。人们一定会认为这是年老的自然衰退。但事实上,对于很大一部分有上述症状的老年人,不仅是因为年纪大了,而主要是因为身体功能退化,骨骼肌肉减少(少肌症)。研究显示,50岁以上的人每年肌肉质量下降1%~2%,而30%的60岁以上或50%的80岁以上老人会发生不同程度的少肌症。少肌症是老年人的多发病,但是少肌症在我国民众中的认知率却很低。有鉴于此,笔者就这一问题做一简要介绍,供读者朋友们参考。 With age, people tend to appear slimmer limbs, muscles soften, feel weak legs, power deterioration, walking slow down and so on. People will surely think this is a natural decline of old age. But in fact, for a large part of the elderly with these symptoms, it is not only because of their age, but mainly because of deterioration of their body functions and reduction of skeletal muscle (sarcopenia). Studies show that muscle mass decreases by 1% to 2% annually in people over 50, while 30% of those over the age of 60 or 50% have symptoms of sarcopenia to varying degrees. Sosomyotic diseases are frequently-occurring in the elderly, but the prevalence of sarcoidosis in our population is very low. In view of this, I make a brief introduction on this issue, for readers reference.
