in October 2018, the European Working Group on Sarcopenia in Older People 2 (EWGSOP2) updated their original definition of sarcopenia to reflect the scientific and clinical evidence that has accumulated over the last decade.
to determine the prevalence of sarcopenia in a large group of community-dwelling older adults using the EWGSOP2 definition and algorithm.
a cross-sectional study.
the nationwide Korean Frailty and Aging Cohort Study (KFACS).
a total of 2,099 ambulatory community-dwelling older adults, aged 70-84 years (mean age, 75.9 ± 4.0 years; 49.8% women) who were enrolled in the KFACS.
physical function was assessed by handgrip strength, usual gait speed, the five-times-sit-to-stand test, the timed up-and-go test, and the Short Physical Performance Battery. Appendicular skeletal muscle mass (ASM) was measured by dual-energy X-ray absorptiometry.
according to the criteria of the EWGSOP2, the sarcopenia indicators of combined low muscle strength and low muscle quantity were present in 4.6-14.5% of men and 6.7-14.4% of women. The severe sarcopenia indicators of combined low muscle strength, low muscle quantity and low physical performance were present in 0.3-2.2% of men and 0.2-6.2% of women. Using the clinical algorithm with SARC-F as a screening tool, the prevalence of probable sarcopenia (2.2%), confirmed sarcopenia (1.4%) and severe sarcopenia (0.8%) was low.
the prevalence of sarcopenia among community-dwelling older individuals varied depending on which components of the revised EWGSOP2 definition were used, such as the tools used to measure muscle strength and the ASM indicators for low muscle mass.
2018 年 10 月，欧洲老年人肌肉减少症工作组 2 （EWGSOP2）更新了其原始的肌肉减少症定义，以反映过去十年积累的科学和临床证据。
使用 EWGSOP2 定义和算法确定大量社区居住的老年人中肌肉减少症的患病率。
横断面研究。
全国韩国虚弱和衰老队列研究（KFACS）。
共纳入 2099 名 70-84 岁（平均年龄 75.9±4.0 岁；49.8%为女性）的社区居住的能走动的老年人，他们参加了 KFACS。
通过握力、常规步行速度、五次坐站试验、起立行走测试和简易体能状况量表评估身体功能。四肢骨骼肌质量（ASM）通过双能 X 射线吸收法测量。
根据 EWGSOP2 的标准，男性肌肉力量和肌肉量均低的肌肉减少症指标的发生率为 4.6%-14.5%，女性为 6.7%-14.4%。男性肌肉力量、肌肉量和身体机能均低的严重肌肉减少症指标的发生率为 0.3%-2.2%，女性为 0.2%-6.2%。使用 SARC-F 作为筛查工具的临床算法，疑似肌肉减少症（2.2%）、确诊肌肉减少症（1.4%）和严重肌肉减少症（0.8%）的患病率较低。
使用 EWGSOP2 修订定义的不同组成部分（如用于测量肌肉力量的工具和低肌肉质量的 ASM 指标），社区居住的老年人肌肉减少症的患病率有所不同。
