Abstract

OBJECTIVES : To examine patterns of muscle mass change with aging and to estimate the prevalence of sarcopenia. DESIGN : Cross‐sectional survey. SETTING : Population‐based study in Rochester, Minnesota. PARTICIPANTS : Age‐stratified sample of men and women from the community. MEASUREMENTS : Muscle mass estimated from total body scans by dual‐energy X‐ray absorptiometry. Sarcopenia was defined as muscle mass more than 2 standard deviations below the sex‐specific young‐normal mean. RESULTS : Total lean body mass (exclusive of bone) and total skeletal muscle mass both were greater in men than women and declined linearly with age as judged from these cross‐sectional data. Adjustment for height reduced the gender difference. The age‐ and sex‐adjusted prevalence of sarcopenia varied from 6 to 15% among subjects 65 years of age or over, depending on the muscle mass parameter that was evaluated, but prevalence rates were quite sensitive to the normal values used to define cutoff levels. Subjects with sarcopenia appeared to have more physical limitations than the others. CONCLUSIONS : Late in life, a substantial portion of the population reaches low levels of muscle mass that are associated with increased physical disability. However, additional efforts are needed to validate an operational definition of sarcopenia. J Am Geriatr Soc 48:625–630, 2000 .

Statistics

Recomputing p-values needs the paper’s full text.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Muscle mass decreases with age, and strength and power decrease as well; after age 30, the rate of muscle mass decline is approximately 3-8% per decade, and it is even more rapid after age 60.

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.
