Abstract

Introduction: Metabolic syndrome (MetS) is a major health concern around the world. Dietary factors, including diet quality, play a significant role in its pathophysiology. Healthy Eating Index (HEI) is a tool used as a valid measurement of the individual's diet quality. We aimed at investigating the relationship between diet quality as assessed by HEI-2015 and the risk of MetS and its components in a cross-sectional sample of suburban individuals from PERSIAN Kavar cohort study (PKCS), Fars province, Iran. Methods: 2225 individuals meeting the eligibility criteria participated in the study. The relevant data were obtained from the baseline phase of PKCS. MetS was defined according to cut-offs presented by the National Cholesterol Education Program Adult Treatment Panel III (ATP III). HEI-2015 was calculated for the included individuals. Odds ratios were estimated. P-values <0.05 were considered as significant. Results: The overall prevalence of MetS was 27.3%. Individuals with lower HEI-2015 scores had higher odds for MetS and its components. We observed that those who were categorized as the top HEI-2015 tertile had 42% (OR: 0.58; 95% CI: 0.38–0.90) lower odds of high blood pressure in the overall population. Also, the odds of high serum triacylglycerol was lower (OR: 0.72; 95% CI: 0.57–0.90) in those with the highest HEI-2015 scores. Conclusion: We found that higher dietary quality measured by HEI will decrease the risk of developing MetS, hypertension, and hypertriglyceridemia among Iranian adults. However, future interventional studies are required to further elucidate the issue. © 2023 European Society for Clinical Nutrition and Metabolism
