为了制定可靠的置信限之间的关系夜间和24小时尿钠排泄用于人口的依从性研究，尿排泄量进行了测量，在12个白色和12个黑人男性在3个水平的钠摄入量（10，200和400毫克当量/天）为76天。夜间Na、Cl和用滴定棒测定的Cl均高度相关（r ≥ 0.05）。0.86，P < 0.001）。没有显著差异可归因于人种。判别分析显示，受试者可以归类为钠摄入量的准确性为95，90和85%（低，中和高钠摄入量，分别）通过2夜间尿氯滴定棒测量。夜间UClV < 10 meq的测量结果表明，24小时UNaV < 60 meq的准确性为95%。显然，测量夜间钠或氯排泄是评估低钠摄入依从性的有用手段。[The讨论了膳食钠在动脉高血压发展中的作用。
To formulate reliable confidence limits for the relationship between nocturnal and 24-h urine Na excretion for use in population compliance studies, urine excretions were measured in 12 white and 12 black men at 3 levels of Na intake (10, 200 and 400 meq/day) for 76 days. Nocturnal Na, Cl and Cl as determined by titrator stick were all highly correlated (r .gtoreq. 0.86, P < 0.001) with 24-h UNaV [urinary Na volume]. No significant difference could be attributed to race. Discriminate analysis revealed that the subjects could be categorized with respect to Na intake with accuracies of 95, 90 and 85% (low, middle and high Na intake, respectively) by means of 2 nocturnal urine Cl titrator stick measurements. Measurements showing nocturnal UClV [urinary Cl volume] < 10 meq indicated with 95% accuracy that 24-h UNaV was < 60 meq. Apparently, measurement of nocturnal Na or Cl excretion is a useful means of assessing compliance to a low Na intake.
