Central obesity, insulin resistance, dyslipidemia, and hypertension are the core components of metabolic syndrome (MetS) which is coincident with unhealthy dietary habits in the Middle-Eastern countries. The aim of this study was to explore the association between dietary habits and MetS of the adult population living in Yazd Greater Area, Iran.
This is a cross-sectional study that uses the data of a population-based cohort study on Iranian adults, known as Yazd Health Study (YaHS). The relationship between dietary habits and metabolic syndrome among adults ( = 2,896) was analyzed using multiple logistic regression method.
The prevalence of MetS among the participants was 32.2%. Outcomes from logistic regression examination show that breakfast consumption has a significant inverse effect on the occurrence of MetS after adjustment for age, education level, physical activity statue, history of chronic diseases, and smoking (odds ratio (OR) = 0.38, 95% confidence interval (CI) = 0.14, 0.97). This effect remains significant even after adjustment for body mass index (BMI) and reveals that odds of having MetS is 69% lower in breakfast consumers in contrast to nonconsumers (OR = 0.31, 95% CI = 0.11, 0.87). However, no significant relationship was observed between other dietary habits including consumption of sweetened drinks, sugar cubes, and fast foods and MetS after adjustment for all potential confounders.
This study revealed that eating breakfast has an inverse relationship with metabolic syndrome. To find out stronger evidence in relation to dietary habits and MetS, more researches especially population-based cohort studies are needed to be conducted.
中心性肥胖、胰岛素抵抗、血脂异常和高血压是代谢综合征（MetS）的核心组成部分，这与中东国家不健康的饮食习惯相一致。本研究的目的是探讨伊朗亚兹德大地区成年人群的饮食习惯与代谢综合征之间的关联。
这是一项横断面研究，使用了一项基于人群的伊朗成年人队列研究（即亚兹德健康研究（YaHS））的数据。采用多因素logistic回归方法分析成年人（n = 2896）饮食习惯与代谢综合征之间的关系。
参与者中代谢综合征的患病率为32.2%。logistic回归分析结果显示，在调整年龄、教育水平、身体活动状况、慢性病病史和吸烟因素后，吃早餐对代谢综合征的发生有显著的负向影响（优势比（OR）= 0.38，95%置信区间（CI）= 0.14，0.97）。即使在调整体重指数（BMI）后，这种影响仍然显著，表明吃早餐者患代谢综合征的几率比不吃早餐者低69%（OR = 0.31，95% CI = 0.11，0.87）。然而，在调整所有潜在混杂因素后，未观察到其他饮食习惯（包括饮用含糖饮料、方糖和快餐）与代谢综合征之间存在显著关系。
本研究表明，吃早餐与代谢综合征呈负相关。为了找到更多关于饮食习惯与代谢综合征的有力证据，需要进行更多的研究，尤其是基于人群的队列研究。
