KIDMED questionnaire among 6–14 years old children was used to assess Mediterranean diet (MD) adherence.
Of 1643 children, 18.4% had a poor and 81.6% a medium-high adherence.
Metabolic syndrome (MS) prevalence was 6.6% and 3.7% respectively.
In children with less physical activity, MS was more frequent vs those more active.
Thus, healthier lifestyle habits and physical activity also impact among children.
