目的评估中国成年人膳食多酚类化合物的摄入量,为多酚健康效应研究和膳食指南制订提供依据。方法利用2011年中国健康与营养调查膳食调查(China Health and Nutrition Survey,CHNS)数据和多酚含量数据库,评估中国成年人膳食多酚类化合物...目的评估中国成年人膳食多酚类化合物的摄入量,为多酚健康效应研究和膳食指南制订提供依据。方法利用2011年中国健康与营养调查膳食调查(China Health and Nutrition Survey,CHNS)数据和多酚含量数据库,评估中国成年人膳食多酚类化合物摄入量,确定主要食物来源,并比较不同人群多酚摄入差异。结果中国成年人每日膳食总多酚、黄酮、酚酸摄入量分别为109.30、59.00和31.59 mg/d,远低于西方和日本等发达国家。蔬菜、水果和谷薯类食物是中国居民膳食多酚类化合物摄入的主要途径,但调查人群水果摄入量远低于中国居民膳食指南标准。总多酚、黄酮、酚酸摄入量男性低于女性,农村低于城市,初中及以下学历人群低于其他人群。总多酚、酚酸摄入量南方低于北方。结论中国人群膳食多酚摄入水平较低,调查资料中非酒精性饮料膳食数据缺失可能是主要影响因素。低学历、南方、农村和男性群体多酚类化合物摄入量相对更少。展开更多
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...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。展开更多

The results indicate that 1） There are three jumps during 1919 - 1923, 1947 - 1953 and 1976 - 1982 in recent hundred years and the stable climate step between two jump points lasted about 30 years. 2） Annual mean temperature is increased by 0. 730℃ in an echelon during 1903 -2000, the warming extent is dissimilarity in each season, the maximum of warming is in the winter and the minimum of warming is in summer. 3） The ice decline trend is presented in the index of Ice concentration in the vicinity sea of Antarctic Peninsula, which shows a -0. 2053/10a drop, and the decrease trend of the ice concentration index in summer half year （Dee-May） is found much more obviously than that in winter half year （Jun-Nov）. 4） There is better negative relationship between the temperature and the Ice concentration index in Antarctic Peninsula and its vicinity sea, which correlation coefficient of is exceed the significance level of 5% in summer, autumn and annual.展开更多
