Baseline characteristics of students in the total sample and according to students’ grades.Data are presented as mean (standard deviation) for normally distributed continuous variables (age) and % of the corresponding sample for categorical variables. For the normally distributed variables (age), p’s were obtained using two-sample Level of adherence to the Mediterranean diet, dietary habits, physical activity, and screen time at baseline and follow-up according to students’ grade.Quantitative variables are presented as mean (sd). Categorical outcomes are presented as proportion to the total outcome group population. Dietary habits emerged from KIDMED questions. Students’ health-related quality of life at baseline and follow-up in the total sample and according to students’ grade.All baseline outcomes are presented as median (IQR) due to non-normal distribution. All differences were calculated as follow-up score—baseline score and are presented as mean (SD) due to normal distribution.
