Abstract

Correction to Levitt DG, Heymsfield SB, Pierson Jr RN, Shapses SA, Kral JG: Physiological models of body composition and human obesity. Nutrition & Metabolism 2007, 4:19

Correction

Since publication of our first article [1] we have noticed that the following corrections needed to be made. There is an error in the calculation of the body fat in the original version of this article. The tritium distribution space was not properly corrected for non-aqueous hydrogen exchange and water density resulting in estimates of percent body fat that are about 2% less then the correct percent. This produces small errors in the regression relations for the prediction of body fat from BMI or body density described originally in Tables 3, 4, 5, 6, 7, 8 and 9. The corrected tables (calculated using TBW = 3H2O × 0.96 × 0.994) are provided.

Table 3. Caucasian males: Dependence of fat fraction on age for two BMI ranges.

Table 4. Caucasian females: Dependence of fat fraction on age for three BMI ranges.

Table 5. Ethnic dependence of BMI versus fat fraction for males.

Table 6. Ethnic dependence of BMI versus fat fraction for females.

Table 7. Comparison of linear (eq. (16)) and non-linear (eq. (9)) regression expressions for predicting body fat fraction from BMI and age.

Table 8. Prediction of fat fraction from BMI for Caucasian + Black + Hispanic subjects.

Table 9. Prediction of fat fraction from body density for Caucasian + Black + Hispanic subjects.
