Topic: Risk, prevention and care in population studies
Background Healthy diets have been associated with better cognitive function. Socioeconomic factors including education, poverty, and job complexity may modify the relationship between diet and cognition. Methods We used adjusted linear mixed models to examine the association between long-term adherence to the Mediterranean-Dietary Approaches to Stop Hypertension - Intervention for Neurodegenerative Delay (MIND) diet and cognitive function over 8 years of follow-up in Puerto Rican adults residing in the Boston, MA area (aged 45-75 years at baseline). We also examined whether the MIND diet-cognition association was confounded or modified by socioeconomic measures. Results In both cross-sectional and longitudinal analyses the highest, versus lowest, MIND quintile was associated with better cognition function (β = 0.093; 95% CI: 0.035, 0.152; p trend = .0019), but not with cognitive trajectory over 8 years. Education <=8th grade (β = -0.339; 95% CI: 0.394, -0.286; p < .0001) and income-to-poverty ratio <120% (β = -0.049; 95% CI: -0.092, -0.007; p = .024) were significantly associated with lower cognitive function, while higher job complexity (β = 0.008; 95% CI: 0.006, 0.011; p < .0001) was associated with better cognition function. These variables acted as confounders, but not effect modifiers of the MIND-diet-cognitive function relationship. Conclusion Adherence to the MIND diet was associated with better cognitive function at baseline and over 8 years of follow-up; however, MIND diet was not associated with 8-year cognitive trajectory. More studies are needed to better understand whether the MIND diet is protective against long-term cognitive decline.
Key findings
- Background Healthy diets have been associated with better cognitive function.
- Results In both cross-sectional and longitudinal analyses the highest, versus lowest, MIND quintile was associated with better cognition function (β = 0.093; 95% CI: 0.035, 0.152; p trend = .0019), but not with cognitive trajectory over 8 years.
- Education <=8th grade (β = -0.339; 95% CI: 0.394, -0.286; p < .0001) and income-to-poverty ratio <120% (β = -0.049; 95% CI: -0.092, -0.007; p = .024) were significantly associated with lower cognitive function, while higher job complexity (β = 0.008; 95% CI: 0.006, 0.011; p < .0001) was associated with better cognition function.
- Conclusion Adherence to the MIND diet was associated with better cognitive function at baseline and over 8 years of follow-up; however, MIND diet was not associated with 8-year cognitive trajectory.

How this study scored 50/100
Published in a peer-reviewed journal, and it is a snapshot of people at one point in time. Scored zero for sample size, effect reported, studied in people 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 29 of the 58 points we could judge it on, which is 50 out of 100.
