Abstract

Objective The aim of the study was to investigate whether there is a difference between body fat mass percentage measured by BIA and DXA method.Design Transversal study, randomized.Setting Lipid and Obesity Outpatient Clinic, Department of Pediatrics, University of Vienna, Austria.Subjects Twenty-seven children and adolescents from the Lipid and Obesity Outpatient Clinic, Department of Pediatrics, University of Vienna, were included in the study (14 boys and 13 girls between 6 and 18 y; mean age 12.6 and 13.1 y).Methods The body fat percentage was measured with BIA (bioelectrical impedance analyzer BIA 2000-M) and DXA (dual energy X-ray absorptiometry) methods on the same day.Results The mean difference between the body fat mass percentage measured by BIA and DXA was 4.48 with a standard deviation of 2.93. The results measured by BIA were almost always lower than that by DXA by about 12%. The lower and upper limit of the difference in 95% confidence interval was -5.64 and -3.32. By paired t-test, these results were significantly different (P<0.001). The correlation between the two measurements was 0.826. The mean percentage of body fat mass measured by BIA was 34.86+/-7.08% and by DXA 39.75+/-5.63%. The differences were not changed by age and body fat percentage but they were by sex.Conclusions The results of the study show that the body fat percentages measured by BIA and DXA method were significantly different. This is very important because BIA technique is a routine technique for clinical purposes. Adjustments to the formula used for calculating the total fat mass in obese children and adolescence are necessary. Underestimation of body fat percentage measured by bioelectrical impedance analysis compared to dual X-ray absorptiometry method in obese children is three times higher with boys than with girls.

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.
