Adherence to the Mediterranean Diet and Its Association with Cognitive Function in Children and Adolescents: A Systematic Review of Observational Studies
Bibliographic record
Abstract
OBJECTIVES: This study aimed to analyze the associations between cognitive functions and adherence to the Mediterranean diet (MedDiet) in children and adolescents. METHODS: A systematic review was conducted in three databases: Pubmed, Scopus, and Web of Science. The inclusion criteria of the studies were (i) population: healthy children or adolescents; (ii) exposure: adherence to the MedDiet; (iii) outcomes: cognitive performance; and (iv) study design: observational studies only. The quality of the studies was assessed through the Newcastle-Ottawa Scale. RESULTS: This systematic review included 12 cross-sectional, observational studies including a total of 6378 children aged 4-17 years from different countries, analyzing diet characteristics and cognitive functions. The quality of the studies was high (Newcastle-Ottawa Scale mean score = 7.42). Positive associations were found between adherence to the MedDiet and multiple cognitive functions: memory, attention, creativity, language skills, and executive functions. However, the wide variety of instruments assessing the adherence to the MedDiet and cognitive functions did not allow us to perform a meta-analysis. CONCLUSIONS: he MedDiet should be further considered and promoted among children and adolescents, as it shows promise as a dietary pattern that may support cognitive development in youth.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
