We investigated the usefulness of measuring urinary salt excretion by using a self-monitoring device. Subjects were 34 hypertensive patients who underwent successful 24-h home urine collection five times and 25 volunteers. Four volunteers were diagnosed as having hypertension based on home blood pressure (BP) readings. All subjects were asked to measure daily urinary salt excretion for 30 days by using a self-monitoring device which estimates 24-h salt excretion by overnight urine. The mean urinary salt excretion during the 30 days was 8.36 +/- 1.52 g/day and the range (maximum-minimum value) was 5.47 +/- 20.05 g/day in all subjects. Mean urinary salt excretion decreased from 8.52 +/- 1.63 g/day for the first 10 days to 8.31 +/- 1.54 g/day for the last 10 days (p < 0.05). The mean urinary salt excretion determined by a self-monitoring device using overnight urine was positively associated with that determined by 24-h home urine for five times in the hypertensive subjects (r = 0.63, p < 0.01). Results indicate that a self-monitoring device seems to be useful to monitor daily salt intake and to guide salt restriction.
我们研究了使用自我监测设备测量尿盐排泄的有用性。受试者为 34 名成功进行了 5 次 24 小时家庭尿液收集的高血压患者和 25 名志愿者。根据家庭血压（BP）读数，有 4 名志愿者被诊断为高血压。所有受试者均被要求使用自我监测设备测量 30 天的日常尿盐排泄量，该设备通过夜间尿液估计 24 小时盐排泄量。所有受试者的 30 天平均尿盐排泄量为 8.36 +/- 1.52 g/天，范围（最大值-最小值）为 5.47 +/- 20.05 g/天。所有受试者的尿盐排泄量从第 10 天的 8.52 +/- 1.63 g/天减少到第 20 天的 8.31 +/- 1.54 g/天（p < 0.05）。使用夜间尿液的自我监测设备确定的尿盐排泄量与高血压患者 5 次 24 小时家庭尿液确定的尿盐排泄量呈正相关（r = 0.63，p < 0.01）。结果表明，自我监测设备似乎可用于监测日常盐摄入量并指导盐限制。
