Topic: Risk, prevention and care in population studies
Objective Our aim was to evaluate the association between adherence to the Mediterranean Diet (MedDiet) and cognitive function in 823 participants (62 ± 6 years at baseline) from a Spanish prospective cohort (SUN project). Method A validated 136-item food frequency questionnaire was used to assess the adherence to the MedDiet at baseline. The 10-point (0 to 9) MedDiet Score was used to categorize adherence to MedDiet. Cognitive function was assessed twice at follow-up with a mean follow-up time between exposure and outcome assessment of 6 and 8y using the Telephone Interview of Cognitive Status-modified (TICS-m, range 0 to 54 points). ANCOVA models were used to assess the association between adherence to the MedDiet and cognitive decline. Results In the multivariable-adjusted analysis of 2-year changes, a higher cognitive decline was observed among participants with low or moderate baseline adherence to the MedDiet than among those with better adherence (adjusted difference = -0.56 points in TICS-m, 95% CI = -0.99 to -0.13). Conclusion A higher adherence to the MedDiet might be associated with better cognitive function. However, observed differences were of small magnitude and further studies are needed to confirm this finding.
Key findings
- Results In the multivariable-adjusted analysis of 2-year changes, a higher cognitive decline was observed among participants with low or moderate baseline adherence to the MedDiet than among those with better adherence (adjusted difference = -0.56 points in TICS-m, 95% CI = -0.99 to -0.13).
- Conclusion A higher adherence to the MedDiet might be associated with better cognitive function.

How this study scored 64/100
Published in a peer-reviewed journal, and it is a prospective cohort study, followed forward from enrollment. Scored zero for effect reported and randomised / blinded because the record does not state it. We have no data on journal's citation record, times cited, citations per year, impact for its field and year, cited by studies here, still being cited, senior author's track record, institution's track record and multi-centre collaboration, so those were left out: it earned 37 of the 58 points we could judge it on, which is 64 out of 100.
