Methods: We evaluated CUN-BAE and body mass index (BMI) as continuous predictors of body fat percentage, total fat mass, and visceral fat. Results: BMI showed stronger correlations with visceral fat (r = 0.941 vs. 0.850) and total fat mass (r = 0.968 vs. 0.828),while CUN-BAE showed a slightly stronger correlation with body fat percentage (r = 0.918 vs. 0.884), the parameter it was designed to estimate. CUN-BAE displayed only a weak correlation with muscle mass (r = 0.153), supporting its specificity for adiposity assessment, whereas BMI showed a moderate correlation with muscle mass (r = 0.551), reflecting its weight-dependent nature. Conclusions: Overall, BMI remains a practical marker of absolute fat mass and visceral adiposity, while CUN-BAE may provide a more refined estimate of relative body fat percentage. Tool selection should be guided by the clinical objective and interpreted as complementary rather than competing measures.<\/jats:p>","DOI":"10.3390\/diagnostics16121786","type":"journal-article","created":{"date-parts":[[2026,6,10]],"date-time":"2026-06-10T06:33:44Z","timestamp":1781073224000},"page":"1786","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Performance of CUN-BAE in Assessing Adiposity and Visceral Fat: A Validation Study Using Bioelectrical Impedance Analysis in a Mexican Population"],"prefix":"10.3390","volume":"16","author":[{"given":"Paulo C\u00e9sar","family":"Gete Palacios","sequence":"first","affiliation":[{"name":"Unidad de Investigaci\u00f3n M\u00e9dica en Enfermedades Endocrinas, Centro M\u00e9dico Nacional Siglo XXI, Instituto Mexicano del Seguro Social, Mexico City 06720, Mexico"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alejandra Fabiola","family":"V\u00e1zquez L\u00f3pez","sequence":"additional","affiliation":[{"name":"Unidad de Investigaci\u00f3n M\u00e9dica en Enfermedades Endocrinas, Centro M\u00e9dico Nacional Siglo XXI, Instituto Mexicano del Seguro Social, Mexico City 06720, Mexico"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0001-8391-0434","authenticated-orcid":false,"given":"Eduardo Salif","family":"Luna-Avila","sequence":"additional","affiliation":[{"name":"Unidad de Investigaci\u00f3n M\u00e9dica en Enfermedades Endocrinas, Centro M\u00e9dico Nacional Siglo XXI, Instituto Mexicano del Seguro Social, Mexico City 06720, Mexico"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0002-6305-616X","authenticated-orcid":false,"given":"Luis Angel","family":"L\u00f3pez-Cruz","sequence":"additional","affiliation":[{"name":"Unidad de Investigaci\u00f3n M\u00e9dica en Enfermedades Endocrinas, Centro M\u00e9dico Nacional Siglo XXI, Instituto Mexicano del Seguro Social, Mexico City 06720, Mexico"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9216-0383","authenticated-orcid":false,"given":"Manuel Ram\u00f3n","family":"Garc\u00eda-S\u00e1enz","sequence":"additional","affiliation":[{"name":"Servicio de Endocrinolog\u00eda, Hospital de Especialidades \u201cDr. Bernardo Sep\u00falveda\u201d, Centro M\u00e9dico Nacional Siglo XXI, Instituto Mexicano del Seguro Social, Mexico City 06720, Mexico"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Emmanuel","family":"Valdez-Solis","sequence":"additional","affiliation":[{"name":"Hospital \u00c1ngeles Tampico, Tampico 89330, Tamaulipas, Mexico"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mario Alberto","family":"Santana-Mata","sequence":"additional","affiliation":[{"name":"M\u00e9dica Bosco, Saltillo 25253, Coahuila, Mexico"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3025-8339","authenticated-orcid":false,"given":"Claudia","family":"Ram\u00edrez-Renter\u00eda","sequence":"additional","affiliation":[{"name":"Unidad de Investigaci\u00f3n M\u00e9dica en Enfermedades Endocrinas, Centro M\u00e9dico Nacional Siglo XXI, Instituto Mexicano del Seguro Social, Mexico City 06720, Mexico"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5159-9856","authenticated-orcid":false,"given":"Aldo","family":"Ferreira-Hermosillo","sequence":"additional","affiliation":[{"name":"Unidad de Investigaci\u00f3n M\u00e9dica en Enfermedades Endocrinas, Centro M\u00e9dico Nacional Siglo XXI, Instituto Mexicano del Seguro Social, Mexico City 06720, Mexico"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,6,10]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"141","DOI":"10.1046\/j.1467-789x.2001.00031.x","article-title":"Beyond body mass index","volume":"2","author":"Prentice","year":"2001","journal-title":"Obes.
