Interest has intensified in the possible role of dietary sodium in the etiology of hypertension and its management. A summary is provided of the evidence relating salt intake to hypertension from three sources: epidemiology of hypertension among societies, observations that management of hypertension is easier at lower intakes of NaCl, and observations that relate blood pressure to urinary output of sodium. The doubts raised about such a relationship are also summarized. Part of the confusion surrounding the relationship between sodium intake (or output) and blood pressure between individuals results from the interplay of other determinents: genetics (family history), weight, body mass index and Na/K ratio. These are discussed and research issues are outlined. The public policy implications of the current information and means for lowering of dietary sodium intake are discussed.
人们对膳食钠在高血压病因及其管理中可能发挥的作用的兴趣日益浓厚。本文总结了来自三个方面的有关盐摄入量与高血压关系的证据：不同社会中高血压的流行病学研究、关于在较低氯化钠摄入量下高血压管理更容易的观察结果，以及将血压与钠的尿排出量相关联的观察结果。同时也总结了对此种关系所提出的疑问。个体之间钠摄入量（或排出量）与血压关系周围的部分困惑源于其他决定因素的相互作用：遗传学（家族史）、体重、体重指数和钠钾比。对这些因素进行了讨论并概述了研究问题。还讨论了当前信息的公共政策影响以及降低膳食钠摄入量的方法。
