以人群为基础的膳食钠摄入量监测标准是24小时尿液检测；然而，这可能受到尿液收集不完全的影响。不同的间接方法评估收集的完整性对估计钠摄入量的影响尚未确定。作者从2009年的一项现有社区研究中招募了507名参与者，收集了24小时的尿样。测试了几种评估尿液收集完整性的方法。根据使用的方法，平均钠摄入量在3648毫克/24小时和7210毫克/24小时之间变化。排除收集时间长于或短于24小时的尿液样本，即使对收集时间的变化进行了修正，也会增加尿钠排泄量。在确定一种间接评估尿液收集完整性的准确方法之前，建议使用对氨基苯甲酸的金标准。努力确保参与者收集完整的尿液样本也是必要的。
The standard for population-based surveillance of dietary sodium intake is 24-hour urine testing; however, this may be affected by incomplete urine collection. The impact of different indirect methods of assessing completeness of collection on estimated sodium ingestion has not been established. The authors enlisted 507 participants from an existing community study in 2009 to collect 24-hour urine samples. Several methods of assessing completeness of urine collection were tested. Mean sodium intake varied between 3648 mg/24 h and 7210 mg/24 h depending on the method used. Excluding urine samples collected for longer or shorter than 24 hours increased the estimated urine sodium excretion, even when corrections for the variation in timed collections were applied. Until an accurate method of indirectly assessing completeness of urine collection is identified, the gold standard of administering para-aminobenzoic acid is recommended. Efforts to ensure participants collect complete urine samples are also warranted.
