Methods

This was a cross-sectional study of 228 community-dwelling adults older than 65 years, presenting with a history or risk of falls, ability to mobilize independently with or without the use of gait aids, and without cognitive impairment.

Results

Prevalence of sarcopenia varied depending on the definition (Table 1). Lowest prevalence of sarcopenia was found in the EWGSOP2 when using the TUG to assess physical performance, with highest prevalence seen when using the 5STS for muscle strength.

Agreement was low-moderate between EWGSOP1 and the various EWGSOP2 definitions, and among the EWGSOP2 definitions (Table 2). Similar agreement was present when using handgrip strength or 5STS for muscle strength assessment according to EWGSOP2. Median

Discussion

The revised EWGSOP2 definition better reflects clinical outcomes and adverse events of sarcopenia, addressing in part the disconnect between low muscle mass and outcomes.4, 5, 6 However, this study found a lack of agreement between EWGSOP1 and 2, and within the EWGSOP2 definitions. This may be explained by the lack of correlation between revised cut-off points and alternate assessments. For example, the 5STS cut-off point of 15 seconds has been linked to falls risk7 (an adverse outcome of

    Other measures that may be considered include 5 sit to stands, Short Physical Performance Battery (SPPB), Timed Up and Go test (TUG), and or 400 m walk test [43]. While the European Working Group on Sarcopenia in Older People 2 (EWGSOP2) definition of sarcopenia advocates for interchangeability of these measures, doing so has been shown to result in vastly different prevalence estimates within the same population group [44]. The Sarcopenia Definition and Outcomes Consortium (SDOC) recently published a data-driven definition of sarcopenia which did not include measures of muscle quality or quantity [45], only handgrip strength and walking speed.
