Abstract

Prior, Barry M., Kirk J. Cureton, Christopher M. Modlesky, Ellen M. Evans, Mark A. Sloniger, Michael Saunders, and Richard D. Lewis. In vivo validation of whole body composition estimates from dual-energy X-ray absorptiometry. J. Appl. Physiol. 83(2): 623–630, 1997.—We validated whole body composition estimates from dual-energy X-ray absorptiometry (DEXA) against estimates from a four-component model to determine whether accuracy is affected by gender, race, athletic status, or musculoskeletal development in young adults. Measurements of body density by hydrostatic weighing, body water by deuterium dilution, and bone mineral by whole body DEXA were obtained in 172 young men ( n = 91) and women ( n = 81). Estimates of body fat (%Fat) from DEXA (%Fat DEXA) were highly correlated with estimates of body fat from the four-component model [body density, total body water, and total body mineral (%Fat d,w,m); r = 0.94, standard error of the estimante (SEE) = 2.8% body mass (BM)] with no significant difference between methods [mean of the difference ± SD of the difference = −0.4 ± 2.9 (SD) % BM, P = 0.10] in women and men. On the basis of the comparison with %Fat d,w,m, estimates of %Fat DEXA were slightly more accurate than those from body density ( r = 0.91, SEE = 3.4%; mean of the difference ± SD of the difference = −1.2 ± 3.4% BM). Differences between %Fat DEXA and %Fat d,w,m were weakly related to body thickness, as reflected by BMI ( r= −0.34), and to the percentage of water in the fat-free mass ( r = −0.51), but were not affected by race, athletic status, or musculoskeletal development. We conclude that body composition estimates from DEXA are accurate compared with those from a four-component model in young adults who vary in gender, race, athletic status, body size, musculoskeletal development, and body fatness.

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?

  • DXA estimates of %BF are accurate, but values can differ by DXA instrumentation.

    “Estimates of %BF are also accurate (11)(12)(13), but values can differ based on the DXA instrumentation utilized (e.g., Lunar, Hologic, Norland).”

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.
