During an epidemiological survey, the dietary intake and urinary excretion of sodium, potassium, calcium and magnesium were measured by means of the 24 h food record method and a 24 h urine collection in 2,112 men and 1,943 women. Significant correlations (P less than 0.001) were found between dietary intake and urinary excretion of the above cations in men and women by univariate analysis and after adjustment for age, height, weight and total caloric intake. Taking into account the difficulty of estimating dietary cation intakes and obtaining complete 24 h urine collections, and the non-coincidence of the 24 h urine collection and the food recording periods, our findings point to a strong positive association between dietary intake and urinary excretion of sodium, potassium, calcium and magnesium. No significant relationship was found between these urinary cations and blood pressure.
在一项流行病学调查中，采用24小时食物记录法和24小时尿液收集法，对2112名男性和1943名女性的钠、钾、钙和镁的膳食摄入量及尿排泄量进行了测量。通过单因素分析以及在对年龄、身高、体重和总热量摄入进行校正后，发现男性和女性上述阳离子的膳食摄入量与尿排泄量之间存在显著相关性（P<0.001）。考虑到估计膳食阳离子摄入量以及获得完整24小时尿液收集的难度，以及24小时尿液收集与食物记录期的不一致性，我们的研究结果表明钠、钾、钙和镁的膳食摄入量与尿排泄量之间存在很强的正相关。未发现这些尿阳离子与血压之间存在显著关系。
