Dietary Patterns Associated with Metabolic Syndrome: A Study Conducted in Khorramabad

Background: Metabolic syndrome (MetS) is a complex disorder considered as aworldwide epidemic. The aim of this study was to characterize the dietarypatterns of Iranian adults and examine its association with metabolic syndrome.Methods: In this cross-sectional study, 973 persons were selected using multistagecluster, random sampling method in Khorramabad city. Dietary intake wasassessed using a validated, 168 food-item, self-administrated, and semiquantitativefood-frequency questionnaire (FFQ). To identify the dietary patterns,factor analysis was used for principal components. Results: Three major dietarypatterns were identified: the western dietary pattern (WDP), the healthy dietarypattern (HDP), and the traditional dietary pattern (TDP). Participants in thehighest quintile of HDP had lower odds of MetS (OR: 0.45; 95% CI: 0.27-0.77)than those in the lowest quintile, whereas those in the highest quintile of theWDP score had greater odds of the MetS (OR: 3.44; 95% CI: 2.08-5.70) thanparticipants of the lowest quintile. Multi linear regression showed that the WDPscore was associated negatively with serum high density lipoprotein-cholesteroland positively with other components of MetS. Even after body mass indexadjustment, the association remained significant, except for fasting plasmainsulin. Conclusions: a HDP is associated with reduced risk of MetS. In contrast,a WDP is associated with a greater risk of the MetS.
