Objectives Sarcopenia is a common disease in the elderly population that causes disability, poor quality of life, and a high risk of death. In the current study, we conducted a meta-analysis to report basic knowledge about the prevalence of sarcopenia in the elderly in Korea.
Methods We searched for articles in the MEDLINE, Cochrane Library, Embase, and Scopus databases published until December 28, 2020. Studies investigating the prevalence of sarcopenia in elderly Koreans aged ≥65 years were included. The methodological quality of the studies was evaluated using the Newcastle-Ottawa scale. Publication bias was evaluated using the Egger test and funnel plots.
Results In total, 3 studies and 2922 patients were included in the meta-analysis. All 3 studies used the European Working Group on Sarcopenia in Older People criteria for the diagnosis of sarcopenia. The total prevalence of sarcopenia was 13.1-14.9% in elderly men and 11.4% in elderly women.
Conclusions This meta-analysis is the first to estimate the pooled prevalence of sarcopenia in elderly Koreans, and its findings suggest that sarcopenia is common in this population. Therefore, attention should be paid to the prevention and control of sarcopenia.

본 연구에서는 노인인구에서 삶의 질 저하 및 높은 사망률을 야기시키는 흔한 질환인 근감소증의 유병률을 조사하고자 메타분석을 시행하였다. 분석에는 65세 이상 한국 노년층의 근감소증 유병률을 조사한 3건의 연구들과 총 2,922명의 대상자가 포함되었으며, 3개의 연구 모두 European Working Group on Sarcopenia in Older People criteria를 통해 근감소증을 진단하였다. 분석 결과, 근감소증의 총 유병률은 남성에서 13.1-14.9%였고, 여성에서는 11.4%였다. 이 결과는 우리나라의 노인 인구에서 근감소증이 흔하게 발생하므로 근감소증의 예방과 통제에 주의를 기울여야 함을 시사한다.

The health insurance system in Korea is well-established and provides benefits for the entire national population. In Korea, when patients are treated at a hospital, the hospital receives a partial payment for the treatment from the patient, and the remaining amount is provided by the health insurance service. The Health Insurance Review and Assessment Service (HIRA) assesses whether the treatment was appropriate. If HIRA deems the treatment appropriate, the doctor can receive payment from the health insurance service. However, this system has several drawbacks. In this study, we aimed to provide examples of the problems that can occur in relation to HIRA assessments in Korea through actual clinical cases.
