*
underweight (BMI< 18.5 kg/m2), normal weight (BMI 18.5 – 24.9 kg/m2), overweight (BMI 25.0 – 29.9 kg/m2), obese I (BMI 30 – 34.9 kg/m2), obese II (BMI 35–39.9 kg/m2), obese III (BMI ≥ 40 kg/m2)
**
Pearson's r correlation coefficient for all of the continuous variables correlated with BMI as a continuous variable. Unless otherwise indicated, all variables significant at the p < 0.0001 level.
