IntroductionAlthough几种方法近似每日钠摄入量和钠/钾比使用休闲尿是可用的，最有用的方法仍然不清楚在日常实践中，并在home.MethodsTwenty-seven参与者测量他们的休闲尿钠/钾比反复使用钠/钾比监测仪，也测量了夜间尿一次，每天使用一个监测设备，提供现场反馈，以估计他们的盐摄入量在不受限制，低盐（LS）（6克/天）和高盐（HS）结果利用过夜尿来估计每日Na的监测方法仍然不敏感，导致在LS饮食期间显著高估和在HS饮食期间低估;在LS和HS饮食期间估计的盐摄入量在3天内稳定在7-8 g/天和9-10 g/天;在非限制、LS和HS饮食的最后一天，平均估计盐摄入量为11.3 g/天、7.9 g/天和9.8 g/天;在低盐和高盐饮食期间的后半部分，估计钠摄入量的变异系数（CV）分别为0.23和0.17。平均尿Na/K摩尔比为5.6，2.5，和5.3的最后一天的非限制性，LS和HS饮食;的CV的每日平均Na/K比为0.41和0.36的LS和HS饮食期间的后半段，分别。LS和HS饮食期间的尿Na/K比在2天内达到平台。以随意尿Na/K比值的日均值为基础的监测方法反映了Na摄入量的实际变化，当估计系数设为2时，估计值跟踪了盐摄入量的实际变化，与隔夜尿估计值的差异较小，LS和HS饮食期间的估计盐摄入量在2-3天内分别稳定在5-6 g/d和10-12 g/d;平均估计盐摄入量为11.0克/天，5.7克/天，和10.7克/天的最后一天的无限制，LS和HS diets.Discussion/ConclusionEstimates的每日钠摄入量来自隔夜尿可能仍然不敏感，在饮食干预。尿钠/钾比值反映了饮食调整期间钠摄入量的实际变化，可作为一个实用的标志，特别是在短期干预期间。从尿钠/钾比值转换为估计盐摄入量可能是有用的，如果系数设置适当的进一步调查。
IntroductionAlthough several approaches for approximating daily Na intake and the Na/K ratio using casual urine are available, the most useful method remains unclear during daily practice and at home.MethodsTwenty-seven participants measured their casual urinary Na/K ratio repeatedly using a Na/K ratio monitor and also measured overnight urine once daily using a monitoring device which delivers on-site feedback to estimate their salt intake under unrestricted, low-salt (LS)(6 g/day), and high-salt (HS)(12 g/day) diets.ResultsThe monitoring method utilizing overnight urine to estimate daily Na remained insensitive, resulting in significant overestimation during the LS diet and underestimation during the HS diet periods; estimated salt intake during the LS and HS diet periods plateaued at 7–8 g/day and 9–10 g/day within 3 day; mean estimated salt intake was 11.3 g/day, 7.9 g/day, and 9.8 g/day on the last day of the unrestricted, LS, and HS diets; the coefficient of variation (CV) of the estimated Na intake was 0.23 and 0.17 in the latter half of the low-and high-salt diet periods, respectively. The mean urinary Na/K molar ratio was 5.6, 2.5, and 5.3 on the last day of the unrestricted, LS, and HS diets; the CV of the daily mean Na/K ratio was 0.41 and 0.36 in the latter half of the LS and HS diet periods, respectively. The urinary Na/K ratio during the LS and HS diet periods plateaued within 2 days. The monitoring method based on the daily mean of the casual urinary Na/K ratio reflected the actual change in Na intake, and the estimated value tracked the actual changes in salt intake with smaller difference than the overnight urine estimates when using the estimation coefficient set at 2; estimated salt intake during the LS and HS diet periods plateaued at 5–6 g/day and 10–12 g/day within 2–3 day; mean estimated salt intake was 11.0 g/day, 5.7 g/day, and 10.7 g/day on the last day of the unrestricted, LS, and HS diets, respectively.Discussion/ConclusionEstimates of daily Na intake derived from overnight urine may remain insensitive during dietary interventions. The urinary Na/K ratio reflects the actual change in Na intake during dietary modification and may serve as a practical marker, particularly during short-term interventions. Conversion from the urinary Na/K ratio to estimated salt intake may be useful, if the coefficient was set appropriate by further investigations.
