Abstract

The objective of this study was to test whether differences between body fat percent (BF%) measured by densitometry and BF% predicted from body mass index (BMI) or bioimpedance (BIA) can be explained by differences in body build. Weight, height, sitting height (leg length), arm length, skeletal widths, BIA, bone mineral content from dual-energy X-ray absorptiometry, and BF% from densitometry were measured in 90 apparently healthy, young adult subjects (age range 18–31 years). The BMI was calculated and BF% predicted from BMI, age, and sex. BF% was also predicted from BIA. BF% measured by densitometry was 29.3 ± 5.0% for women and 14.6 ± 5.1% for men. BF% predicted from BIA (27.1 ± 6.7% in women, 19.0 ± 6.0% in men) was significantly different from measured values in both sexes. BF% predicted from BMI (25.9 ± 2.2% for women, 15.6 ± 2.4% for men) was only significantly different from BF% from densitometry in women, not in men. In both sexes skeletal widths, especially elbow width, were related to the prediction error of BF% from BMI, confirming the hypothesis that BF% predicted from BMI underestimates BF% in persons with a relatively slender body build or frame. The prediction error of BF% from BIA was found to be related to the length of the arms and legs, confirming the hypothesis that BIA overestimates BF% in persons with relatively long limbs.

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.
