膳食矿物质及微量元素摄入量与血压关系的研究

对山东省４１６０名成年人膳食矿物质和微量元素摄入量及人体测量指标与收缩压（ＳＢＰ）和舒张压（ＤＢＰ）进行了相关分析，对高血压组和正常组膳食矿物质和微量元素摄入量进行了比较，并观察高血压者某些矿物质和微量元素摄入量的分布。结果表明，年龄和ＢＭＩ与ＳＢＰ、ＤＢＰ相关程度密切。Ｓｅ和Ｚｎ摄入量与ＳＢＰ和ＤＢＰ呈正相关（Ｐ＜０．０１），Ｃａ仅与ＳＢＰ正相关（Ｐ＜０．０１），Ｍｇ和Ｆｅ摄入量与ＳＢＰ和ＤＢＰ负相关（Ｐ＜０．０１）。高血压组Ｓｅ和Ｚｎ摄入量高于正常血压组，而Ｍｇ和Ｆｅ摄入量低于正常血压组。在３９６名高血压者中，Ｍｇ摄入量小于２００ｍｇ／ｄ者占１６．６％，而≥９００ｍｇ／ｄ者仅占４．８％。Ｓｅ摄入量≥８５μｇ／ｄ者占１７．５％，而小于１５μｇ／ｄ者占２．７％，高血压发生的危险性似乎随Ｍｇ摄入量的减少或Ｓｅ摄入量的增加而增加。

The Studies on Dietary Minerals and Trace Elements Correlates of Blood Pressure

The relationships between systolic and diastolic pressure(SBP and DBP)and dietary minerals and trace elements were examined for the sample of 4160 adults.18 years and over.The correlation analysis was used to examin the relationship of blood pressure to each of variables.Age and BMI were correlated positively with SBP and DBP(PWTBZ〗<0.01).Se and Zn ingestion were correlated positively with SBP and DBP(P<0.01).There was only positive corrlation between Ca intake and SBP(P<0.01).Mg and Fe ingestion were corrlated inversly with SBP and DBP(P<0.01).Significant decreases in the ingestion of Mg and Fe and significant increase in the ingestion of Se and Zn in the hypertensive group.The risk of being hypertensive increased with decreaments in the ingestion of Mg and with increament in the ingestion of Se.
