As recognized by the World Health Organization in 2016 with its inclusion in the International Classification of Diseases, Tenth Revision as M62.84, and by South Korea in 2021 as M62.5, the diagnostic guidelines for sarcopenia vary globally. Despite its prevalence in older populations, data on sarcopenia in Koreans aged 60 and above is scarce, highlighting the need for research on its prevalence in this demographic.
Utilizing the 2022 Korea National Health and Nutrition Examination Survey dataset, sarcopenia was assessed among 1,946 individuals aged 60 or older according to the Asian Working Group for Sarcopenia 2019 criteria, incorporating grip strength and bioelectrical impedance analysis measurements. Statistical analyses were performed to differentiate categorical and continuous variables using logistic regression and Student's t-tests, respectively.
The prevalence of sarcopenia was found to increase with age, with the highest prevalence observed in the oldest age group (80 years and older). The overall prevalence of sarcopenia in our study population was 6.8%. Among men, the prevalence of sarcopenia was 5.5% in the 60 or older age group, 9.6% in the 70 or older age group, and 21.5% in the 80 or older age group. Among women, the prevalence of sarcopenia was 7.9%, 10.5%, and 25.9%, respectively.
This study highlights the significant burden of sarcopenia in elderly Koreans, particularly among the oldest individuals. These findings call for targeted interventions to manage and prevent sarcopenia, along with further research on its risk factors, consequences, and effective mitigation strategies.
2016年，世界卫生组织将其纳入《国际疾病分类》第十次修订版，编码为M62.84；2021年，韩国将其编码为M62.5，全球肌肉减少症的诊断指南各不相同。尽管肌肉减少症在老年人群中普遍存在，但关于60岁及以上韩国人肌肉减少症的数据却很稀少，这凸显了对该人群中肌肉减少症患病率进行研究的必要性。
利用2022年韩国国家健康与营养检查调查数据集，根据亚洲肌肉减少症工作组2019年的标准，对1946名60岁及以上的个体进行了肌肉减少症评估，评估内容包括握力和生物电阻抗分析测量。分别使用逻辑回归和学生t检验进行统计分析，以区分分类变量和连续变量。
肌肉减少症的患病率随年龄增长而增加，在最高年龄组（80岁及以上）中患病率最高。我们研究人群中肌肉减少症的总体患病率为6.8%。在男性中，60岁及以上年龄组的肌肉减少症患病率为5.5%，70岁及以上年龄组为9.6%，80岁及以上年龄组为21.5%。在女性中，肌肉减少症的患病率分别为7.9%、10.5%和25.9%。
本研究突出了韩国老年人中肌肉减少症的重大负担，尤其是在最年长者中。这些发现呼吁采取针对性干预措施来管理和预防肌肉减少症，并进一步研究其风险因素、后果及有效的缓解策略。
