Public health programs and policies can positively influence food environments. In 2016, a voluntary National Healthy Food and Drink Policy was released in New Zealand to improve the healthiness of food and drinks for hospital staff and visitors. However, no resources were developed to support policy implementation.
This study aimed to design, develop, and test a new web-based tool to support food providers implementing the National Healthy Food and Drink Policy in New Zealand.
The Double Diamond model, a structured framework with 4 design phases, was used to design and develop a web-based tool. Findings from our previous research, such as (1) systematic review of barriers and facilitators to workplace healthy food policy implementation; (2) scoping review of current tools and resources available in New Zealand, Australia, and Canada; (3) interviews with food providers and public health nutrition professionals; and (4) food and drink availability audit results in New Zealand hospitals were used in the "Discover" (understanding of current gaps) and "Define" (prioritizing functions and features) phases. Subsequent phases focused on generating ideas, creating prototypes, and testing a new web-based tool using Figma, a prototyping tool. During the "Develop" phase, project stakeholders (11 public health nutrition professionals) provided feedback on the basic content outline of the initial low-fidelity prototype. In the final "Deliver" phase, a high-fidelity prototype resembling the appearance and functionality of the final tool was tested with 3 end users (public health nutrition professionals) through interactive interviews, and user suggestions were incorporated to improve the tool.
A new digital tool, Healthy Kai (Food) Checker-a searchable database of packaged food and drink products that classifies items according to the Policy's nutritional criteria-was identified as a key tool to support Policy implementation. Of 18 potential functions and features, 11 were prioritized by the study team, including basic and advanced searches for products, sorting list options, the ability to compile a list of selected products, a means to report products missing from the database, and ability to use on different devices. Feedback from interview participants was that the tool was easy to use, was logical to navigate, and had an appealing color scheme. Suggested visual and usability improvements included ensuring that images represented the diverse New Zealand population, reducing unnecessary clickable elements, adding information about the free registration option, and including more frequently asked questions.
Comprehensive research informed the development of a new digital tool to support implementation of the National Healthy Food and Drink Policy. Testing with end users identified features that would further enhance the tool's acceptability and usability. Incorporation of more functions and extending the database to include products classified according to the healthy school lunches program policy in the same database would increase the tool's utility.
公共卫生项目和政策能够对食物环境产生积极影响。2016年，新西兰发布了一项自愿性的《国家健康食品与饮料政策》，旨在改善医院工作人员和访客所食用食物和饮料的健康程度。然而，并未开发出相关资源来支持该政策的实施。
本研究旨在设计、开发并测试一种新型的基于网络的工具，以支持食品供应商在新西兰实施《国家健康食品与饮料政策》。
采用双钻石模型（一个包含4个设计阶段的结构化框架）来设计和开发基于网络的工具。我们先前研究的结果，例如：（1）对工作场所健康食品政策实施的障碍和促进因素进行系统评价；（2）对新西兰、澳大利亚和加拿大现有的工具和资源进行范围审查；（3）对食品供应商和公共卫生营养专业人员进行访谈；（4）新西兰医院食品和饮料供应情况审计结果，被用于“发现”（了解当前差距）和“定义”（确定功能和特性的优先级）阶段。后续阶段则专注于产生想法、创建原型，并使用原型设计工具Figma测试一种新型的基于网络的工具。在“开发”阶段，项目利益相关者（11名公共卫生营养专业人员）对初始低保真原型的基本内容大纲提供了反馈。在最后的“交付”阶段，通过交互式访谈对3名最终用户（公共卫生营养专业人员）测试了一个与最终工具外观和功能相似的高保真原型，并纳入了用户建议以改进该工具。
一种新的数字工具——健康食物（Kai）检查器（一个可搜索的包装食品和饮料产品数据库，根据该政策的营养标准对产品进行分类）被确定为支持该政策实施的关键工具。在18项潜在功能和特性中，研究团队确定了11项优先功能，包括产品的基本搜索和高级搜索、列表排序选项、编制所选产品列表的能力、报告数据库中缺失产品的方式以及在不同设备上使用的能力。访谈参与者的反馈是该工具易于使用、导航逻辑清晰且配色方案吸引人。建议的视觉和可用性改进包括确保图片能代表多样化的新西兰人口、减少不必要的可点击元素、添加有关免费注册选项的信息以及纳入更多常见问题解答。
全面的研究为支持《国家健康食品与饮料政策》实施的新型数字工具的开发提供了依据。对最终用户的测试确定了可进一步提高该工具可接受性和可用性的特性。纳入更多功能并扩展数据库以在同一数据库中包括根据健康学校午餐计划政策分类的产品，将提高该工具的实用性。
