Abstract

The long known and often studied decrease in basal metabolic rate (BMR) with age was recently shown related to changes in the proportion of lean-to-fat tissue mass in the body. Earlier studies from this laboratory showed the decline in basal 0, consumption (basal 00,) to be accounted for by a decline in lean body mass (LBM). The purpose of the present study was to identify and account for that component of the lean body responsible for the age-related decrease in basal vo, in 959 participants in the Baltimore Longitudinal Study aged from 20 to 97 yr, An age-independent linear relation was found between paired values of basal voz, a measure of total metabolic activity, and 24-h creatinine excretion, a measure proportional to skeletal muscle mass. The relation is quanti-fied by basal Tie, = 99.1 + 0.079 (creatinine excretion), where basal vo, is expressed in mllmin (STPD) and creatinine excre-

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.
