Model 1 is a crude model. Model 2 controls for age, gender, father’s education, mother’s education, etc. Model 3 controls for waist circumference, daily moderate to high intensity physical activity, and maximal oxygen uptake (VO_2max) based on model 2. a indicates p < 0.05, b indicates p < 0.01, and c indicates p < 0.001.
