Dietary salt intake and urinary sodium excretion were compared in normotensive and hypertensive subjects in Renfrew, Scotland. All groups had high 24-hour urinary salt excretions, and hypertensive subjects did not eat or excrete more salt than normotensive subjects. The only significant relations found were a lower sodium excretion in hypertensive women than in normotensive women (p < 0.02) and a lower urinary sodium concentration in hypertensive men than in normotensive men (p < 0.05). These data provide no support for the hypothesis that dietary salt is a major cause of hypertension.
在苏格兰伦弗鲁,对血压正常和高血压受试者的膳食盐摄入量和尿钠排泄量进行了比较。所有组的24小时尿盐排泄量都很高,高血压受试者摄入和排泄的盐并不比血压正常的受试者多。唯一显著的关系是,高血压女性的钠排泄量低于血压正常的女性(p < 0.02),高血压男性的尿钠浓度低于血压正常的男性(p < 0.05)。这些数据不支持膳食盐是高血压主要病因这一假说。
