Abstract

BACKGROUND:

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.

OBJECTIVE:

to determine the prevalence of sarcopenia in a large group of community-dwelling older adults using the EWGSOP2 definition and algorithm.

DESIGN:

a cross-sectional study.

SETTING:

the nationwide Korean Frailty and Aging Cohort Study (KFACS).

SUBJECTS:

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.

METHODS:

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.

RESULTS:

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.

CONCLUSIONS:

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.
