Abstract
OBJECTIVES: Although some components of MIND diet were associated with stroke, no information is available on the association between adherence to the MIND diet and odds of stroke. This study was conducted to investigate the association between adherence to the MIND diet and odds of stroke among Iranian adults. METHODS: This case-control study was done on 193 hospitalized stroke cases and 195 hospital-based controls in Al-Zahra hospital, Isfahan, Iran. Dietary intakes of study participants were assessed using a validated 168-item food frequency questionnaire (FFQ). The MIND diet score was computed based on participants' dietary intakes obtained from FFQ. Stroke was confirmed by a trained neurologist using standard imaging methods. RESULTS: After controlling for age, sex, energy intake, physical activity, smoking, hypertension, diabetes, dyslipidemia, and heart disease, there was no significant association between adherence to the MIND diet and stroke (OR: 0.54; 95% CI: 0.26, 1.12). However, after further adjustment for BMI, we found that those with the greatest adherence to the MIND diet were less likely to have stroke compared with those with the lowest adherence; such that greater adherence to the MIND diet was associated with a 59% reduced odds of stroke (OR: 0.41; 95% CI: 0.18-0.94). CONCLUSION: In conclusion, we found that adherence to the MIND diet was inversely associated with odds of stroke in a case-control study. Further studies are required to confirm these findings.
