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

Background: metabolic syndrome (mets) is a complex disorder considered as a worldwide epidemic. the aim of this study was to characterize the dietary patterns of iranian adults and examine its association with metabolic syndrome. methods: in this cross-sectional study, 973 persons were selected using multi-stage cluster, random sampling method in khorramabad city. dietary intake was assessed using a validated, 168 food-item, self-administrated, and semi-quantitative food-frequency questionnaire (ffq). to identify the dietary patterns, factor analysis was used for principal components. results: three major dietary patterns were identified: the western dietary pattern (wdp), the healthy dietary pattern (hdp), and the traditional dietary pattern (tdp). participants in the highest 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 the wdp score had greater odds of the mets (or: 3.44; 95% ci: 2.08-5.70) than participants of the lowest quintile. multi linear regression showed that the wdp score was associated negatively with serum high density lipoprotein-cholesterol and positively with other components of mets. even after body mass index adjustment, the association remained significant, except for fasting plasma insulin. conclusions: a hdp is associated with reduced risk of mets. in contrast, a wdp is associated with a greater risk of the mets.
