Reviewer 2 Report

Comments and Suggestions for Authors

The manuscript confirms the results already highlighted in the literature by many studies although it refers to a population of school students aged 12-18 years. In this regard, the reviewer does not consider the manuscript original although it is aimed at a specific population since according to the newspaper's indications that an "article" must be original and report scientifically sound experiments and provide a substantial amount of new information. the manuscript, if the journal allows it, could be published as a "communication" where the results obtained can be reported, highlighting the differences in a significant way compared to other studies
