There is sound evidence associating high salt intake and a greater risk of cardiovascular and noncardiovascular diseases. High salt intake has been observed in several populations worldwide. Therefore, promoting healthier salt consumption has been encouraged as a low-cost strategy to reduce this risk factor. However, these strategies need to be sound, built on theoretical and methodological bases, and consider the target population's context.
This protocol aims to describe a mobile phone app intervention to promote healthy salt intake among adults.
This is an experimental and longitudinal study protocol conducted in three modules. Module 1 refers to the planning of the intervention based on the Behaviour Change Wheel framework. Module 2 is the development of the mobile phone app intervention based on the date of module 1. In module 3, the intervention will be evaluated using a randomized controlled study, with three steps of data collection in a 2-month follow-up in a sample of 86 adults (43 participants for each group: the control group and intervention group) recruited from the primary health care centers of a Brazilian town. The discretionary salt intake questionnaire will assess salt consumption, the app usability will be assessed using the System Usability Scale, and psychosocial variables (habit, intention, and self-efficacy) will also be measured.
Recruitment began in October 2021, and the follow-up will end in August 2022. The results of this study are expected to be published in 2023.
Results from this study will help people to control salt intake when cooking at home, will stimulate self-care, will work as an alternative or supportive method in the relationship between health care professionals and patients, and will contribute to implementing the app intervention to promote healthy salt intake on a large scale.

有充分证据表明高盐摄入与心血管疾病和非心血管疾病风险增加有关。全球多个群体都存在高盐摄入的情况。因此，鼓励推广更健康的盐消费作为降低这一风险因素的低成本策略。然而，这些策略需要合理，建立在理论和方法基础之上，并考虑目标人群的背景。
本方案旨在描述一种通过手机应用程序干预来促进成年人健康盐摄入的方法。
这是一项分三个模块进行的实验性纵向研究方案。模块1指基于行为改变轮框架进行干预规划。模块2是根据模块1的数据开发手机应用程序干预。在模块3中，将采用随机对照研究对干预进行评估，在从巴西一个城镇的初级卫生保健中心招募的86名成年人（对照组和干预组各43名参与者）样本中，进行为期2个月的随访，分三个步骤收集数据。自行选择盐摄入量问卷将评估盐的消费情况，应用程序可用性将使用系统可用性量表进行评估，心理社会变量（习惯、意图和自我效能）也将进行测量。
招募工作于2021年10月开始，随访将于2022年8月结束。本研究结果预计于2023年发表。
本研究结果将有助于人们在家烹饪时控制盐摄入量，激发自我保健意识，在医护人员与患者的关系中作为一种替代或辅助方法发挥作用，并有助于大规模实施促进健康盐摄入的应用程序干预。
