Abstract

BACKGROUND/OBJECTIVES:

Nowadays, metabolic syndrome (MetS) is deemed as a major public health challenge in both developed and developing countries. Therefore, the aim of this study was to determine the association between Healthy Eating Index-2010 (HEI-2010) score and MetS and its features among Iranian female nurses.

SUBJECTS/METHODS:

This cross-sectional study was performed among 1036 Iranian women. A validated, self-administered, dish-based, semiquantitative food frequency questionnaire was used to assess the habitual intake of participants. HEI-2010 score was used to assess diet quality of participants. MetS was defined based on the guidelines of the National Cholesterol Education Program Adult Treatment Panel III (ATP III). Multivariate logistic regression adjusted for potential confounders was used to assess the relation between HEI-2010 and MetS.

RESULTS:

After adjusting for potential confounders, participants in the highest quartile of HEI-2010 had the lowest risk of MetS compared with those in the first quartile (odds ratio: 0.72; 95% confidence interval: 0.50-0.96). Furthermore, the risk of MetS features including abdominal obesity, high blood pressure, high serum triacylglycerol and low serum high-density lipoprotein-cholesterol significantly decreased across HEI-2010 quartiles (P < 0.05).

CONCLUSIONS:

Higher HEI-2010 scores were inversely associated with lower risk of MetS and its components among Iranian women.
