Statistical methods / analysis
The calculation of the sample size will be made in Open Epi, in its section of difference of means, considering the water intake and the standard deviation of the CG and IG in an intervention (Garipaaoulo, 2008). With a confidence level of 95% and a power of 80%, considering a mean consumption of the CG of 470 ml and a standard deviation of 165 ml, and an average consumption of the IG of 504 ml and a standard deviation of 150 ml, it is necessary to include:
676 children in total
• Control of the Group: 338 students.
• Intervention Group: 338 students

A descriptive analysis of the sociodemographic variables will be carried out: the qualitative variables will be expressed as frequencies and percentages, while the quantitative variables will be expressed as mean and standard deviation or as median and percentiles, depending on the distribution of the variables.
The frequencies of consumption of beverages will be analyzed descriptively according to the nature of the variables, in addition the test Xi2 and Mc Nemar will be used, to compare the results between groups and intra group, in each measurement time
For dietary data, the comparison of the consumption of each study group (baseline-post and post-intervention measurement) will be made, comparing the GC with the IG, for this analysis the paired student's T test or Wilcoxon will be used (intra comparison groups) and student T or U Mann Whitney for independent samples (comparison between groups). In addition, the Friedman test will be used to determine the change in consumption through the measurement times.
