Methods: This study measured body fat percentage (BFP), fat mass (FM), and fat-free mass (FFM) in 26 pediatric patients with obesity (BMI: 35.6\u00b16.9 kg\/m2), using two bioelectrical impedance analysis (BIA) devices (TANITA and BIACORPUS), and the results were compared to those of the gold-standard dual-energy X-ray absorptiometry (DXA). Additionally, air displacement plethysmography (BODPOD) was compared with DXA, and all methods were evaluated against each other. Results: Significant differences were observed between all methods and parameters (p &lt; 0.05). For example, Bland\u2013Altman analysis for BFP identified differences between BIACORPUS and DXA (mean: \u22123.5%; 95% limits of agreement: \u221216.7% to 9.8%) and between TANITA and DXA (mean: \u22123.1%; 95% limits of agreement: \u221212.2% to 6.1%). These differences can be regarded as clinically relevant, especially when considering the 95% limits of agreement. Further, moderate differences between BODPOD and DXA were identified, which could be clinically relevant (mean: 2.1%; 95% limits of agreement: \u22124.2% to 8.5%). Conclusions: TANITA was the most comparable BIA method to the gold standard, DXA. Therefore, TANITA is recommended for assessing body composition in young patients with obesity to monitor therapy progress in clinical settings. When using BODPOD as an alternative to DXA, caution is warranted since we found relevant differences between both methods.<\/jats:p>","DOI":"10.3390\/nu17060971","type":"journal-article","created":{"date-parts":[[2025,3,10]],"date-time":"2025-03-10T12:02:59Z","timestamp":1741608179000},"page":"971","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":11,"title":["Comparing Bioelectrical Impedance Analysis, Air Displacement Plethysmography, and Dual-Energy X-Ray Absorptiometry for Body Composition in Pediatric Obesity"],"prefix":"10.3390","volume":"17","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-1051-1141","authenticated-orcid":false,"given":"Alexandra","family":"Thajer","sequence":"first","affiliation":[{"name":"Division of Pediatric Pulmonology, Allergology and Endocrinology, Department of Pediatrics and Adolescent Medicine, Medical University of Vienna, 1090 Vienna, Austria"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Martin","family":"Vasek","sequence":"additional","affiliation":[{"name":"Division of Pediatric Pulmonology, Allergology and Endocrinology, Department of Pediatrics and Adolescent Medicine, Medical University of Vienna, 1090 Vienna, Austria"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sophie","family":"Schneider","sequence":"additional","affiliation":[{"name":"Division of Pediatric Pulmonology, Allergology and Endocrinology, Department of Pediatrics and Adolescent Medicine, Medical University of Vienna, 1090 Vienna, Austria"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3520-4105","authenticated-orcid":false,"given":"Alexandra","family":"Kautzky-Willer","sequence":"additional","affiliation":[{"name":"Gender Medicine Unit, Division of Endocrinology and Metabolism, Department of Internal Medicine III, Medical University of Vienna, 1090 Vienna, Austria"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Franz","family":"Kainberger","sequence":"additional","affiliation":[{"name":"Division of Neuro- and Musculoskeletal Radiology, Department of Biomedical Imaging and Image-Guided Therapy, Medical University of Vienna, 1090 Vienna, Austria"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sebastian","family":"Durstberger","sequence":"additional","affiliation":[{"name":"Department Health Sciences, FH Campus Wien\u2014University of Applied Sciences, 1100 Vienna, Austria"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1665-6958","authenticated-orcid":false,"given":"Andreas","family":"Kranzl","sequence":"additional","affiliation":[{"name":"Orthopaedic Hospital Speising, Laboratory of Gait and Movement Analysis, 1130 Vienna, Austria"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9296-3212","authenticated-orcid":false,"given":"Brian","family":"Horsak","sequence":"additional","affiliation":[{"name":"Institute of Health Sciences, St. P\u00f6lten University of Applied Sciences, 3100 St. P\u00f6lten, Austria"},{"name":"Center for Digital Health & Social Innovation, St. P\u00f6lten University of Applied Sciences, 3100 St. P\u00f6lten, Austria"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3706-8370","authenticated-orcid":false,"given":"Susanne","family":"Greber-Platzer","sequence":"additional","affiliation":[{"name":"Division of Pediatric Pulmonology, Allergology and Endocrinology, Department of Pediatrics and Adolescent Medicine, Medical University of Vienna, 1090 Vienna, Austria"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2025,3,10]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"435","DOI":"10.1016\/j.clnu.2011.12.011","article-title":"Body composition: Why, when and for who?","volume":"31","author":"Thibault","year":"2012","journal-title":"Clin.
