A Survey of the Relationship Between Dietary Quality and Metabolic Syndrome

Background Dietary intake is increasingly recognized as a pivotal factor in the etiology of metabolic syndrome. A substantial body of evidence suggests a discernible correlation between dietary quality indices and the occurrence of metabolic syndrome.Objective This survey seeks to rigorously evaluate the impact of diet quality indices and demographic variables on the manifestation of metabolic syndrome.Materials and Methods This case-control study encompassed 175 individuals diagnosed with metabolic syndrome and an equal number of age-matched healthy counterparts (Comprising both genders) aged between 20 and 65 years. Participants were sourced from diverse laboratories and the general population in Chalous, northern Iran. Dietary intake data were meticulously acquired using a comprehensive Food Frequency Questionnaire (FFQ). Furthermore, dietary quality indices, specifically the Healthy Eating Index (HEI), Dietary Diversity Score (DDS), Nutrient Adequacy Ratio (NAR), and Mean Adequacy Ratio (MAR), were meticulously evaluated employing standardized methodologies.Results There was no significant diversity in the likelihood of developing metabolic syndrome concerning the Healthy Eating Index (HEI), Nutrient Adequacy Ratio (NAR), and Mean Adequacy Ratio (MAR) when comparing quartile 4 (Maximum score) to quartile 1 (Minimum score). However, this likelihood diminished following adjustments for confounding variables, including age, sex, dietary energy, education, job, and marital status. In the case of the Dietary Diversity Score (DDS), there was an observed difference in morbidity likelihood between quartile 4 and quartile 1. Nevertheless, after meticulous adjustment for confounding variables, this difference failed to reach statistical significance. No substantial variations (P >= 0.05) were detected in the odds ratio across quartiles and models (P trend) for all dietary quality indices.Conclusion No significant associations were identified between dietary quality indices and the occurrence of metabolic syndrome.
