  1. a p value for categorical variables refer to the comparison of cases vs. controls using chi-square tests, and for continuous variables refer to the linear regression analysis adjusted for the effect of matching and clustering at the school level.
  2. b Intake estimates of fructose, lipids and proteins were energy adjusted using the residual method [23].
  3. CR: cardiovascular risk.
