A Systematic Review of Behaviour Change Technologies for Influencing Healthy Nutrition

使用技术来支持人们的体重管理工作和影响营养是加拿大的一个发展中的研究领域，而英国的数字健康工具是由全科医生规定的。目前数字健康工具设计的最新水平尚不清楚。此外，目前还没有一个框架来指导这些技术的设计和开发。这项研究旨在通过与英国学者的合作来填补这些空白。这项国际合作的主要目标是为能够影响健康营养的数字化工具的开发制定一个设计框架。为了实现这一目标，我们将对加拿大和英国现有的营养技术进行系统的文献综述，以确定目前存在的技术类型，用于其开发的平台，技术的特点，设计背后的哲学或理论，为某些人口统计开发的特定功能或平台，技术评估的方式，以及，这些技术在促使人们选择更健康的食物方面的成功率。然后，我们将在加拿大和英国进行用户研究，以验证文献综述的结果。此外，我们将比较两国的结果，以确定相似性和差异。预期的成果是开发一个设计框架，用于创建数字健康工具，这些工具可以由加拿大的医疗保健从业者推荐给他们的患者，以支持健康营养习惯的发展。这项研究很重要，因为它将为研究人员提供调查和探索英国研究人员创造和使用的成功技术和工具的机会，以影响人们的饮食习惯。由此产生的框架将指导技术的开发，以支持患者养成更健康的营养习惯。从长远来看，这可以降低加拿大的肥胖增长率，这将减轻医疗保健部门的压力和肥胖并发症引起的疾病。

The use of technologies to support people's weight management efforts and to influence nutrition is a developing research area in Canada compared to the UK where digital health tools are prescribed by GPs. The current state of the art in the design of digital health tools is unknown. In addition, there is currently no framework to guide the design and development of such technologies. This research aims to fill these gaps with a collaboration with a UK-based academic. The main objective of this international collaboration is to develop a design framework for the development of digital tools that can influence healthy nutrition. To achieve this we will carry out a systematic literature review of existing technologies for nutrition in Canada and the UK to identify the types of technologies that currently exist, the platforms that were used for their development, the features of the technologies, the philosophy or theories behind the design, specific features or platforms developed for certain demographics, the way the technologies were evaluated and, the success rate of the technologies in making people adopt healthier food choices. We will then carry out user studies in Canada and the UK to validate the findings from the literature review. Furthermore, we will compare the results from both countries to identify similarities and differences. The anticipated outcome is the development of a design framework for creating digital health tools that can be recommended by healthcare practitioners in Canada to their patients to support the development of healthy nutrition habits. This research is important as it will provide researchers with the opportunity to investigate and explore successful technologies and tools that were created and used by UK researchers to influence peoples' eating habits. The resulting framework will guide the development of technologies that can support patients in developing healthier nutrition habits. This, in the long run, can decrease the obesity growth rate in Canada which will reduce the strain on the healthcare sector and diseases caused by the complications of obesity.
