高盐饮食对血脂代谢的影响

EXCESSIVE SALT INTAKE EFFECT TO LIPID METABOLISM

本文以社区人群为研究对象，探讨了高盐饮食对血脂代谢的影响。单因素方差分析结果显示：高密度脂蛋白胆固醇（ＨＤＬ）及其亚组分（ＨＤＬ３）在高盐饮食组显著低于低盐饮食组（Ｐ＜０．０５）。分层分析调整血压变量后，无论在正常血压组或是在高血压组，钠盐嗜入与ＨＤＬ３仍有显著的负相关关系。但钠盐摄入与ＨＤＬ的负相关关系不再具有显著性（Ｐ＞０．０５）。这主要是由于分层后每层样本含量较小之故。鉴于高盐饮食是高血压的危险因素及高密度脂蛋白胆固醇下降及高血压皆是冠心病的重要危险因素，因此减少钠盐摄入量对高血压及冠心病的一级预防具有重要意义。

he subjects screened from a factory workers to study the effective excessive salt intake and lipid metabolism。The analysis of variance indicated that the levels of HDL3 in thehigh level salt intake group were significant lower than those lower level salt intake group(P<0.05).After the adjust- ment of the blood pressure,there was a significant negative relationship between the level of salt intake and HDL3,but not found significant correlation be- tween the level of salt intake in the both of normoten- sion and hypertension groups。The later may be main- ly caused by small sample size in each stratified data。The over salt consumption is one of the risk factor of hypertension and to decrease of HDL and hyperten- sion is also a risk factor of the all of the coronary heart disease,It is an important to reduce the salt in- take in the primary prevention of the hypertension and coronary heart disease。
