There are no known methods to easily evaluate the dietary salt intake of children. We hypothesized that the salt check sheet, for which validity has been confirmed in both hypertensive outpatients and in the general population, can be used to assess dietary salt intake in children. We enrolled 188 healthy schoolchildren (mean age 11.2 ± 1.1 years, 53.2% boys) and asked them to answer both the salt check sheet and a brief self-administered dietary history questionnaire for Japanese schoolchildren aged 6-18 years (BDHQ15y). The mean total salt check-sheet score was 12.7 ± 4.0 points (range: 4-24 points), and the estimated daily salt intake from the BDHQ15y was 12.1 ± 3.7 g (range: 4.7-27.2 g). The total check-sheet score was significantly positively correlated with the estimated daily salt intake from the BDHQ15y (r = 0.408, P < 0.001). Thirty-one study participants were assigned to the "low" salt group (total score on the salt check sheet was 0-8 points), 78 participants to the "medium" salt group (9-13 points), and 79 participants to the "high and very high" salt group (≥14 points), and a comparison estimating daily salt intake from the BDHQ15y among the three groups was performed. Daily salt-intake levels tended to increase as the group of total check-sheet scores increased: "low" vs "medium" vs "high and very high" salt group levels were 9.5 ± 3.1 vs 11.6 vs 13.5 ± 3.9, respectively (P < 0.001). This demonstrates that the salt check sheet is a useful tool to easily assess dietary salt intake in children.
目前尚无简便评估儿童摄盐量的方法。我们假设已在高血压门诊患者和一般人群中得到验证的盐摄入量检查表可用于评估儿童的膳食盐摄入量。我们纳入了 188 名健康的学龄儿童（平均年龄 11.2±1.1 岁，53.2%为男性），并要求他们回答盐摄入量检查表和一份针对 6-18 岁日本学龄儿童的简短自我管理膳食史问卷（BDHQ15y）。盐摄入量检查表的平均总分 12.7±4.0 分（范围：4-24 分），BDHQ15y 估计的每日盐摄入量为 12.1±3.7g（范围：4.7-27.2g）。盐摄入量检查表总分与 BDHQ15y 估计的每日盐摄入量呈显著正相关（r=0.408，P<0.001）。31 名研究参与者被分配到“低盐”组（盐摄入量检查表总分 0-8 分），78 名参与者分到“中盐”组（9-13 分），79 名参与者分到“高盐和极高盐”组（≥14 分），并对三组的 BDHQ15y 估计的每日盐摄入量进行了比较。盐摄入量检查表总分越高，每日盐摄入量水平越高：“低盐”组与“中盐”组与“高盐和极高盐”组的盐摄入量分别为 9.5±3.1g、11.6±3.9g 和 13.5±3.9g（P<0.001）。这表明盐摄入量检查表是一种简单评估儿童膳食盐摄入量的有用工具。
