The aim of this study was to evaluate the performance of BAI in estimating percentage body fat (BF%) in a sample of Colombian collegiate young adults. The participants were comprised of 903 volunteers (52% females, mean age = 21.4 years ± 3.3). We used the Lin’s concordance correlation coefficient, linear regression, Bland–Altman’s agreement analysis, concordance correlation coefficient (ρc) and the coefficient of determination (R 2 ) between BAI, and BF%; by bioelectrical impedance analysis (BIA)). The correlation between the two methods of estimating BF% was R 2 = 0.384, p < 0.001. A paired-sample t-test showed a difference between the methods (BIA BF% = 16.2 ± 3.1, BAI BF% = 30.0 ± 5.4%; p < 0.001). For BIA, bias value was 6.0 ± 6.2 BF% (95% confidence interval (CI) = −6.0 to 18.2), indicating that the BAI method overestimated BF% relative to the reference method. Lin’s concordance correlation coefficient was poor (ρc = 0.014, 95% CI = −0.124 to 0.135; p = 0.414). In Colombian college students, there was poor agreement between BAI- and BIA-based estimates of BF%, and so BAI is not accurate in people with low or high body fat percentage levels. application/pdf https://doi.org/10.3390/nu9010040 2072-6643 http://repository.urosario.edu.co/handle/10336/14784 eng 13 1 Nutrients Nutrients, ISSN 2072-6643 (2017); pp. 1-13 https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5295084/pdf/nutrients-09-00040.pdf info:eu-repo/semantics/openAccess Abierto (Texto Completo) http://www.mdpi.com/about/openaccess http://www.sherpa.ac.uk/romeo/issn/1824-7288/es/ instname:Universidad del Rosario reponame:Repositorio Institucional EdocUR Body Composition Validity Students Body Adiposity Fisiología humana Obesidad Adiposidad Síndrome Metabólico Body Adiposity Index Performance in Estimating Body Fat Percentage in Colombian College Students : Findings from the FUPRECOL-Adults Study article info:eu-repo/semantics/publishedVersion Artículo
