Body fat percentage prediction in older adults: Agreement between anthropometric equations and DXA

BackgroundIt is difficult to measure body fat percentage in clinical settings. Equations using anthropometric measures are more feasible and can be used estimate fat. However, there a need analyze their accuracy older adults. Our study aims validate the use of equations men women.MethodsThis evaluated data from 127 Brazilian individuals aged between 60 91 years. Weight, height, skinfold thickness waist hip circumferences were measured. Seventeen tested crossed validity criteria suggested by Lohman graph analysis proposed Bland Altman Lin was also performed. The gold-standard method for comparing dual-energy absorptiometry X-ray (DXA).ResultsThe average 30.2 ± 8.6% 43.4 7.9% women (p < 0.001). In men, which presented amplitude 11.48%, while women, amplitude's constant error (CE) 22.88%. based on BMI CE variation −5.3% 29.68% estimation percentage, means that same male individual have total adiposity diagnosed with 34.98% variation, depending selection employed equation.
