A 24-hour urine collection was carried out during a cardiovascular survey in eastern Finland. The study population comprised 148 hypertensive subjects in a random sample of the middle-aged population and 86 normotensive controls. The mean sodium excretion was 197 mmol/24h in both normotensive and hypertensive men, 179 mmol/24h in normotensive women, and 174 mmol/24h in hypertensive women. There were no significant differences in potassium excretion rate or in sodium: potassium molar ratio between the normotensive and the hypertensive among either men or women. There was no statistically significant correlation between blood pressure level and sodium or potassium excretion or sodium: potassium molar ratio. One in four of the subjects reported that they usually added salt to their food before tasting it. The results of this study show that the average level of salt intake in a Finnish population is high, and so is the sodium: potassium molar ratio. Although there was no correlation between sodium excretion and blood pressure levels, it is known that in this population the average blood pressure level is high and cardiovascular disease extremely frequent.
在芬兰东部进行的一项心血管调查期间，进行了24小时尿液收集。研究人群包括中年人群随机样本中的148名高血压患者和86名血压正常的对照者。血压正常的男性和高血压男性的平均钠排泄量均为197 mmol/24小时，血压正常的女性为179 mmol/24小时，高血压女性为174 mmol/24小时。男性或女性中，血压正常者和高血压者之间的钾排泄率或钠钾摩尔比均无显著差异。血压水平与钠或钾排泄或钠钾摩尔比之间无统计学显著相关性。四分之一的受试者报告说，他们通常在品尝食物之前就加盐。这项研究的结果表明，芬兰人群的平均盐摄入量很高，钠钾摩尔比也很高。虽然钠排泄与血压水平之间没有相关性，但已知该人群的平均血压水平较高，心血管疾病极为常见。
