Abstract

Objective: Cardiovascular diseases (CVDs) are the major causes of death, worldwide. Although for decades the associations between individual foods and nutrients and CVDs have been investigated, little attention has been paid to dietary patterns. Therefore, this study was conducted to examine the association between dietary patterns and CVD risk factors among Iranian adults. Methods: This cross-sectional study was performed on 236 adults who attended public health centers. Dietary intakes were collected using a valid food frequency questionnaire. Sociodemographic characteristics, anthropometric measures, and biochemical biomarkers were measured using standardized methods. Dietary patterns derived using the factor analysis. Logistic regression assessed the odds of CVD risk factors across tertiles of data-driven dietary patterns. Results: We identified three dietary patterns. After adjusting for possible confounders, we observed that participants in the third category of the healthy dietary pattern (HDP) had lower odds of low HDL-C (OR = 0.26; 95% CI: 0.10–0.64) compared to those in the first category. Adherence to the mixed pattern was associated with increased odds of high serum TC in men only (OR = 3.69; 95% CI: 1.06–12.81). However, women with higher adherence to the Western dietary pattern (WDP) had higher odds of high serum TG (OR = 5.61; 95% CI: 1.69–18.59), and those with a greater adherence to HDP had lower odds of low HDL-C (OR = 0.25; 95% CI: 0.07–0.98). Conclusion: This study showed that adherence to HDP may protect against a low level of HDL-C, whereas mixed and Western-type diets may contribute to high serum TG levels. Future longitudinal studies are needed to assess the potential causality of the observed associations. © 2020
