钠/钾比率被认为是一个有用的指数，监测它可以有效地减少钠和增加钾，因为实用的方法（自我监测设备和可靠的个人估计从现场尿）可用于评估这些水平的个人。一项降低Na/K比值的干预试验表明，Na/K比值的降低主要涉及Na的减少，K的变化很小。本研究的目的是澄清饮食钠摄入量和尿钠/钾摩尔比之间的关系，使用标准化的低盐和高盐饮食，与相同的饮食钾摄入量，以确定相应的钠/钾比。14名健康的年轻成年志愿者分别摄入低盐（每天3克盐）和高盐（每天20克盐）膳食7天。使用便携式尿Na/K计，参与者在每次排尿时测量他们的现场尿，并在每个饮食期的最后一天收集24小时尿。在无限制、低盐和高盐饮食期的最后一天，24小时尿Na/K比的组平均值分别为4.2、1.0和6.9，而每日平均点尿Na/K比的组平均值分别为4.2、1.1和6.6。尿Na/K比值跟踪饮食盐摄入量的变化，并在每次饮食变化后约3天达到平台期。经常监测现场尿钠/钾比值可能有助于个人坚持适当的饮食钠摄入量。
The Na/K ratio is considered to be a useful index, the monitoring of which allows an effective Na reduction and K increase, because practical methods (self-monitoring devices and reliable individual estimates from spot urine) are available for assessing these levels in individuals. An intervention trial for lowering the Na/K ratio has demonstrated that a reduction of the Na/K ratio mainly involved Na reduction, with only a small change in K. The present study aimed to clarify the relationship between dietary Na intake and the urinary Na/K molar ratio, using standardized low- and high-salt diets, with an equal dietary K intake, to determine the corresponding Na/K ratio. Fourteen healthy young adult volunteers ingested low-salt (3 g salt per day) and high-salt (20 g salt per day) meals for seven days each. Using a portable urinary Na/K meter, participants measured their spot urine at each voiding, and 24-h urine was collected on the last day of each diet period. On the last day of the unrestricted, low-salt, and high-salt diet periods, the group averages of the 24-h urine Na/K ratio were 4.2, 1.0, and 6.9, while the group averages of the daily mean spot urine Na/K ratio were 4.2, 1.1, and 6.6, respectively. The urinary Na/K ratio tracked changes in dietary salt intake, and reached a plateau approximately three days after each change in diet. Frequent monitoring of the spot urine Na/K ratio may help individuals adhere to an appropriate dietary Na intake.
