Aims.-The physiological and clinical importance of body composition is part of public health, nutrition and sports medicine. Common methods for estimating total body adiposity are hydrodensitometry, whole-body potassium counting, plethysmography, bioelectrical impedance analysis and laboratory based dual energy X-ray absorptiometry (DXA), nuclear magnetic resonance and computed tomography. The aim of this study is to verify the suitability of 157 out of more than 600 existing anthropometry equations estimating percent adipose tissue in a cross-validation with DXA, bioelectrical impedance analysis and hydrodensitometry on 74 British male subjects (mean age: 34.4 +/- 14.1 years) with different lifestyles corresponding to a maximum of populations the original formula was developed for.
Methods and results.-Pearson correlation coefficients (r >= 0.70), paired sample t test and Bland and Altman plots where used for analyses. From the tested formulae, 19 correlated well and showed no significant difference (p>0.05) with bioelectrical impedance analysis, 15 with DXA and 12 with hydrodensitometry. The results show a better match of the predicted percent adipose tissue by anthropometric equations with bioelectrical impedance analysis then with DXA and hydrodensitometry.
Conclusion.-All results and conditions considered, this study suggests not to use hydrodensitometry and anthropometric equations to assess percent adipose tissue in men for an individual diagnosis.
