Objective: To compare estimates of body density (Db) from air-displacement plethysmography (ADP) with measured and predicted thoracic-gas-volume (TGV) measurements and those from hydrodensitometry (HD) in children. Methods: Seventeen participants (13 male and 4 female; 10.1 +/- 2.20 yr, 42.0 +/- 15.03 kg, 145.6 +/- 17.41 cm, 30.0 +/- 8.66 kg/m(2)) were tested using ADP and HD, with ADP always preceding HD. Db estimates were compared between ADP with measured TGV, ADP with predicted TGV, and the reference measure, HD. Regression analyses were used to assess the accuracy of the ADP methods, and potential bias between the ADP procedures and HD were evaluated using Bland-Altman analyses. The cross-validation criteria described by Lohman for estimating Db relative to HD were used to interpret the results of the study. Results: A significant difference was found between Db estimates from ADP with measured TGV (1.0453 +/- 0.01934 g/cm(3)) and ADP with predicted TGV (1.0415 +/- 0.01858 g/cm(3)); however, neither was significantly different from Db obtained by the reference HD procedure (1.0417 +/- 0.02391 g/cm(3)). For both ADP procedures, regression analyses produced an r = .737.738, r(2) = .543-.544, and SEE = 0.02 g/cm(3), and the regression lines deviated significantly from the line of identity; however, no significant biases were indicated. Conclusions: Despite no significant mean differences between Db estimates from the ADP procedures and HD, more cross-validation research is needed before recommending the BOD POD for routine use with children in clinical and research settings.
