中国农村人群膳食多酚与高血压的相关性分析

Correlation Analysis of Dietary Polyphenol Intake and Hypertension in China’s Rural Population

目的探究中国农村人群膳食多酚摄入与高血压的关系。方法选用2011年"中国健康与营养调查"(China Health and Nutrition Study, CHNS)数据,评估中国农村地区人群的多酚摄入和新发高血压的患病率情况;将研究人群按照总多酚及其亚类摄入量的四分位数分为为4组,采用Logistic回归模型分析其与高血压患病率之间的关系。结果相比于最低黄酮类摄入水平(Q1),最高摄入水平(Q4)可以降低人群28%的高血压患病风险(OR=0.72;95%CI:(0.55~0.95);P-trend=0.009);但未观察到总多酚、酚酸类、木质素类和其他类多酚摄入与高血压患病率存在显著关联。结论较高水平的黄酮类多酚摄入是高血压的保护因素。本研究可为膳食多酚对高血压的健康效应提供理论参考。

Objective To evaluate the association between dietary polyphenols intake and hypertension in China’s rural population.Methods Data from the 2011 China Health and Nutrition Survey(CHNS)were used to estimate the dietary polyphenols intake and the prevalence of newly diagnosed hypertension in rural Chinese population.The study objects were divided into four groups according to the quartile of total polyphenols and subclasses intake.Logistic regression models were used to assess the relationship between polyphenols intake and hypertension.Results Compared with the lowest quartile group, participants in the highest quartile of flavonoids intake group had a 28% decrease in risk of hypertension(OR=0.72;95% CI:(0.55-0.95);P-trend=0.009).Total polyphenols, phenolic acids, lignans and other polyphenols intake were not significantly associated with the prevalence of hypertension.Conclusion Higher dietary intake of flavonoids is a protective factor for hypertension, which would provide theoretical support for the health effects of dietary polyphenols on hypertension.
