NA: not available; UWW: underwater weighing; DXA: dual-energy X-ray absorptiometry; Cauc: caucasians; SKF: skinfold; Tric: tricipital; Sub: subscapular; M: male; F: female; SPA: single photon absorptiometry; Deut Dilut: deuterium dilution; : coefficient of determination; RMSE: root of mean square error; CV: coefficient of variation; CCC: concordance correlation coefficient; PE: pure error; FM: fat mass; Prepub: prepubescent; Pub: pubescent; Postpub: postpubescent. The authors used a sample aged 8–29 years but recommended the use of the proposed models for children and adolescents aged 8–18 years. %FM = {(2.747/Db) ‒ (0.727 * TBW/) + (1.146 * BMC/) − 2.053 100, where Db body density; TBW: total body water; BMC: bone mineral content; : body weight [66].
