The relationship between urinary cations and blood pressure has been examined by means of multiple regression analysis with the inclusion of age, BMI, urinary 24-hour creatinine, heart rate and the 24-hour urinary excretion of Na, K and, in a subsample, of Ca and Mg. In Korea where the Na intake is high and the K intake is low a significant positive relationship was found between 24-hour urinary Na and blood pressure and a negative one between 24-hour urinary K and blood pressure. In Belgium, however, a negative relationship was found between 24-hour urinary Na and the Na/K ratio and blood pressure. In a subsample the 24-hour urinary Mg excretion significantly and negatively correlated with diastolic blood pressure both in men (slope -0.245 mm Hg/mmol Mg) and in women (slope -0.525 mm Hg/mmol Mg) while no significant relationship was found with 24-hour urinary Ca. Further study of the importance of Mg for blood pressure regulation is warranted.
通过多元回归分析研究了尿阳离子与血压之间的关系，分析中纳入了年龄、体重指数、24小时尿肌酐、心率以及24小时尿钠、钾排泄量，在一个子样本中还纳入了钙和镁的24小时尿排泄量。在钠摄入量高而钾摄入量低的韩国，发现24小时尿钠与血压之间存在显著正相关，24小时尿钾与血压之间存在负相关。然而，在比利时，24小时尿钠、钠/钾比值与血压之间呈负相关。在一个子样本中，24小时尿镁排泄量与男性（斜率为-0.245 mmHg/mmol镁）和女性（斜率为-0.525 mmHg/mmol镁）的舒张压均呈显著负相关，而与24小时尿钙未发现显著关系。有必要进一步研究镁对血压调节的重要性。
