  1. aCalculated with Chi-square test for categorical variables and with T-test for the continuous variables
  2. Physical activity was defined as high when in the highest quartile of the whole group, and lower when in the three lower quartiles [14]
  3. Values are number of individuals and percentage or mean and standard deviation. p < 0.05 was considered statistically significant
