膳食盐是成人液体摄入量的主要决定因素；然而，人们对儿童中的这种关系知之甚少。含糖软饮料的消费与儿童肥胖有关，但尚不清楚盐和含糖软饮料的消费之间是否存在联系。我们分析了一项横断面研究的数据，即英国年轻人的国家饮食和营养调查。使用 7 天的饮食记录评估了 1688 名 4 至 18 岁参与者的盐摄入量和液体摄入量。调整潜在的混杂因素后，盐摄入量和总液体量以及含糖软饮料消耗量之间存在显着相关性（P < 0.001）。盐摄入量的差异为 1 克/天，总液体摄入量和含糖软饮料消耗量的差异分别为 100 克/天和 27 克/天。这些结果与其他证据，特别是来自仅改变盐摄入量的实验研究的证据，表明盐是儿童时期液体和含糖软饮料消费的主要决定因素。如果英国儿童的食盐摄入量减少一半（平均减少量：3 克/天），则每个儿童每周平均减少约 2.3 杯含糖软饮料。因此，减少盐摄入量可以通过影响含糖软饮料的消费来帮助减少儿童肥胖。这将对预防心血管疾病产生有益的影响，独立于减盐对血压的影响，并且与减盐对血压的影响相辅相成。
Dietary salt is a major determinant of fluid intake in adults; however, little is known about this relationship in children. Sugar-sweetened soft drink consumption is related to childhood obesity, but it is unclear whether there is a link between salt and sugar-sweetened soft drink consumption. We analyzed the data of a cross-sectional study, the National Diet and Nutrition Survey for young people in Great Britain. Salt intake and fluid intake were assessed in 1688 participants aged 4 to 18 years, using a 7-day dietary record. There was a significant association between salt intake and total fluid, as well as sugar-sweetened soft drink consumption (P < 0.001), after adjusting for potential confounding factors. A difference of 1 g/d in salt intake was associated with a difference of 100 and 27 g/d in total fluid and sugar-sweetened soft drink consumption, respectively. These results, in conjunction with other evidence, particularly that from experimental studies where only salt intake was changed, demonstrate that salt is a major determinant of fluid and sugar-sweetened soft drink consumption during childhood. If salt intake in children in the United Kingdom was reduced by half (mean decrease: 3 g/d), there would be an average reduction of approximate to 2.3 sugar-sweetened soft drinks per week per child. A reduction in salt intake could, therefore, play a role in helping to reduce childhood obesity through its effect on sugar-sweetened soft drink consumption. This would have a beneficial effect on preventing cardiovascular disease independent of and additive to the effect of salt reduction on blood pressure.
