The previous evidence shows that there is an association between total dietary polyphenols intake (DPI) and its subclasses and lower risk of metabolic Syndrome (MetS). This cross-sectional study aims to evaluate associations between DPI and cardiometabolic factors in Iranian women.
A total of 404 Iranian women were included in this study. Dietary intakes and polyphenols intakes were measured using a validated semi-quantitative food frequency questionnaire (FFQ) and the Phenol-Explorer database, respectively. Biochemical variables and blood pressure were evaluated using Pars Azmoon kits and mercury sphygmomanometer.
The mean intake of total polyphenol was 2533.96 ± 1223.67 g. While there were significant negative associations between stilbenes and lignans intake and body mass index (BMI) (P-value = 0.04; P-value = 0.02, respectively), beverages containing phenolic acids and hip circumference (HC) (P-value = 0.02), total polyphenols intake and weight to hip ratio (WHR) (P-value = 0.04). Also there was significant negative associations between stilbenes intake and cholesterol (CHOL) level (P-value = 0.03), other polyphenols intake and triglyceride (TG) ((P-value = 0.01), lignan intake and homeostasis model assessment insulin resistance (HOMA-IR) (P-value = 0.03).
These findings demonstrated that dietary polyphenols were associated with cardiometabolic factors in Iranian women. Prospective and interventional studies in both genders, different populations and ethnicities need to be conducted to further the knowledge about examine associations between consumption of polyphenols and metabolic component.
之前的证据表明，总膳食多酚摄入量（DPI）及其亚类与代谢综合征（MetS）风险降低之间存在关联。本横断面研究旨在评估伊朗女性 DPI 与心脏代谢因素之间的关系。
本研究共纳入 404 名伊朗女性。膳食摄入量和多酚摄入量分别通过经过验证的半定量食物频率问卷（FFQ）和 Phenol-Explorer 数据库进行测量。使用 Pars Azmoon 试剂盒和汞柱血压计评估生化变量和血压。
总多酚的平均摄入量为 2533.96±1223.67g。虽然 stilbenes 和 lignans 摄入量与体重指数（BMI）（P 值=0.04；P 值=0.02）之间存在显著负相关，含酚酸的饮料和臀围（HC）（P 值=0.02），总多酚摄入量与腰臀比（WHR）（P 值=0.04）之间存在显著负相关。此外，stilbenes 摄入量与胆固醇（CHOL）水平（P 值=0.03）之间存在显著负相关，其他多酚摄入量与甘油三酯（TG）（P 值=0.01）之间存在显著负相关，lignan 摄入量与稳态模型评估胰岛素抵抗（HOMA-IR）（P 值=0.03）之间存在显著负相关。
这些发现表明，膳食多酚与伊朗女性的心脏代谢因素有关。需要在男性、不同人群和不同种族中进行前瞻性和干预性研究，以进一步了解检查多酚消耗与代谢成分之间的关系。
