中国的食盐摄入量很高，约80%是由消费者添加的。在这样的环境下，很难减少盐分。我们之前的研究(以学校为基础的减少盐的教育方案(School-EduSalt))表明，教育学童，然后指导他们的家庭减少家里使用的盐量，在降低儿童和成年人的盐分摄入量方面都是有效的。我们的团队还开发了一款名为KnowSalt的应用程序，它可以帮助个人估计自己的盐分摄入量和饮食中的主要盐分来源。在学校教育盐和知识盐的基础上，我们建议开发一款新的APP(AppSalt)，专注于通过教育、目标设定、监测、评估、决策支持和管理来减少盐的摄入量，以实现长期渐进的低盐摄入量。为评价该计划的实施效果，我们将进行整群随机对照试验。方法与分析在中国县抽取三省城乡的54所小学。将随机抽取594名8-9岁儿童和1188名成年家庭成员进行评估。在基线评估后，学校将被随机分配到干预组或控制组。干预组将在AppSalt的支持下，向儿童传授减盐知识，并布置家庭作业，让全家参与到减少食盐消费的活动中来。干预的期限为两个学期(即一年)。主要结果是干预组和对照组在24小时尿钠测定的盐摄入量变化上的差异。伦理和传播这项研究已经得到玛丽女王研究伦理委员会和北京大学健康科学中心IRB的批准。结果将通过演示文稿、出版物和社交媒体传播。
Introduction Salt intake is very high in China, with approximate to 80% being added by the consumers. It is difficult to reduce salt in such settings. Our previous study (School-based Education programme to reduce Salt(School-EduSalt)) demonstrated that educating schoolchildren, who then instructed their families to reduce the amount of salt used at home, is effective in lowering salt intake in both children and adults. Our team also developed an app called 'KnowSalt', which could help individuals to estimate their salt intake and the major sources of salt in the diet. Building on School-EduSalt and KnowSalt, we propose to develop a new app (AppSalt) focusing on salt reduction through education, target setting, monitoring, evaluation, decision support and management to achieve a progressive lower salt intake for long term. To evaluate the effectiveness of the AppSalt programme, we will carry out a cluster randomised controlled trial.Methods and analysis We will recruit 54 primary schools from urban and rural areas of three provinces in China. A total of 594 children aged 8-9 years and 1188 adult family members will be randomly selected for evaluation. After baseline assessment, schools will be randomly allocated to either the intervention or control group. Children in the intervention group will be taught, with support of AppSalt, about salt reduction and assigned homework to get the whole family involved in the activities to reduce salt consumption. The duration of the intervention is two school terms (ie, 1 year). The primary outcome is the difference between the intervention and control group in the change of salt intake as measured by 24-hour urinary sodium.Ethics and dissemination The study has been approved by Queen Mary Research Ethics Committee and Peking University Health Science Centre IRB. Results will be disseminated through presentations, publications and social media.
