The main analysis was based on the intention-to-treat population.
*P value: McNemar tests (changes in each group).
†P value: generalised linear models (differences in the changes from baseline to end of intervention of the intervention and control groups).
‡Sugary drinks, accounting for three categories: commercial juice, sodas and cokes.
