Adherence to Alternative Healthy Eating Index (AHEI-2010) is not associated with risk of stroke in Iranian adults: A case-control study.
Background: Stroke is a major global health problem that contributes to a significant burden of morbidity and mortality. The association of several foods and nutrients with stroke has been well-established. However, the effect of the whole diet on stroke is poorly understood. In this work, we aimed to examine the association between the quality of whole diet, as measured using Alternate Healthy Eating Index-2010 (AHEI-2010), and risk of stroke in Iranian adults. Methods: In this hospital-based case-control study, 193 stroke patients (diagnosed based on clinical and brain CT findings) and 193 controls with no history of cerebrovascular diseases or neurologic disorders were included. The participants' dietary intakes were examined using a validated 168-item semi-quantitative food frequency questionnaire. AHEI-2010 was constructed based on earlier studies. Participants were classified according to tertiles of AHEI-2010 scores and multivariate logistic regression was used to evaluate the association between whole diet quality and risk of stroke. Results: Individuals with greater adherence to AHEI-2010 had a higher intake of fruits, vegetables, nuts and legumes, whole grains and carbohydrate, and a lower intake of trans-fatty acids, sugar-sweetened beverages, total energy and fat (P < 0.05). After adjusting for potential confounders, adherence to AHEI-2010 was not significantly associated with a reduced risk of stroke (OR: 0.92; 95% CI: 0.56-1.51). Conclusion: We found that adherence to AHEI-2010 was not associated with risk of stroke in Iranian adults. Further prospective studies are warranted to validate this finding and clarify the relationship between whole diet and stroke.
