Abstract

Aim: To develop cut‐off points of muscle mass, gait speed and handgrip strength; and to examine the prevalence of sarcopenia, and the relationship between sarcopenia stages and functional limitations and disability by using these cut‐off points. Methods: We pooled individual participant data of 2867 community‐dwelling older adults from five cohort studies. We defined the cut‐off point of a muscle mass index (ASM/ht 2) as the values of two standard deviations below the sex‐specific means of a young population or as the 20th percentile of the sex‐specific distribution in our study population. The gait speed and handgrip strength cut‐off points were defined as the 20th percentile of their population distributions. We also measured functional limitations, using the S hort P hysical P erformance B attery, and the number of activities of daily living and instrumental activities of daily living difficulties. Results: We identified the cut‐off points of ASM/ht 2, gait speed and handgrip strength. By applying these cut‐off points to our study population, the prevalence of sarcopenia varied from 3.9% (2.5% in women and 5.4% in men) to 7.3% (6.5% in women and 8.2% in men). A higher sarcopenia stage was independently associated with a lower summary performance score, as well as more activities of daily living and instrumental activities of daily living difficulties (P < 0.05 for all). Conclusions: The prevalence of sarcopenia in community‐dwelling older adults is comparable with those in other populations. A dose–response relationship exists between sarcopenia stages and functional limitations/disability. The E uropean W orking G roup on S arcopenia in O lder P eople consensus definition using these cut‐off points is suitable for determining sarcopenia cases in the elderly population of T aiwan.

  • Researchers have shown significant differences and bias in the prevalence of sarcopenia when different cut points of distinct populations are used instead of the original sex-specific group of subjects.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
