Influence of Sarcopenia on the Development of Physical Disability: The Cardiovascular Health Study

Janssen, Ian·2006·Journal of the American Geriatrics Society

Abstract

OBJECTIVES: To examine the temporal relationship between sarcopenia and disability in elderly men and women. DESIGN: Cardiovascular Health Study, a longitudinal study of cardiovascular disease and its risk factors in older people. SETTING: Four U.S. communities. PARTICIPANTS: Five thousand thirty‐six men and women aged 65 and older. MEASUREMENTS: Whole‐body skeletal muscle mass was measured at baseline, and subjects were classified as having normal muscle mass, moderate sarcopenia, or severe sarcopenia based on previously established thresholds. Disability was measured via questionnaire at baseline in up to eight annual follow‐up examinations. The cross‐sectional relationship between sarcopenia and prevalent disability at baseline was examined using logistic regression models. The longitudinal relation between sarcopenia and incident disability over 8 years of follow‐up was examined using Cox proportional hazards models. RESULTS: At baseline, the likelihood of disability was 79% greater in those with severe sarcopenia ( P <.001) but was not significantly greater in those with moderate sarcopenia ( P= .38) than in those with normal muscle mass. During the 8‐year follow‐up, the risk of developing disability was 27% greater in those with severe sarcopenia ( P= .006) but was not statistically greater in those with moderate sarcopenia ( P= .23) than in those with normal muscle mass. CONCLUSION: Severe sarcopenia was a modest independent risk factor for the development of physical disability. The effect of sarcopenia on disability was considerably smaller in the longitudinal analysis than in the cross‐sectional analysis.

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.
