  1. † The baseline regression model included only level of physical activity (PA) and intercept. Regression coefficient of the intercept term was not shown.
  2. # Forward regression modeling was used for entering demographic variables: sex, age and puberty. Demographic variables significant in any pervious models were retained. Regression coefficient of the intercept term was not shown.
  3. SE, standard error of the coefficients; PA, physical activity; ref, reference group of the categorical variable analyzed by creating dummy variables
  4. * Cardiovascular Score = Sum of components' z score: components of cardiovascular risk score include z-score of sex-specific, age-adjusted waist circumference, systolic blood pressure (also height-adjusted), fasting plasma glucose, triglyceride and total cholesterol (TC)/high-density lipoprotein cholesterol (HDL-C) ratio.
