PROJECT SUMMARY Obesity, unhealthy dietary habits, and food insecurity are major public health concerns, especially affecting individuals living in poverty. Food pantries, which provide free food to those in need, are increasingly interested in promoting healthy choices, but few rigorous studies have tested low-cost, behavioral interventions to encourage healthy food choices in food pantry settings. The overall objective of this proposal is to conduct a 1-year randomized-controlled trial among 500 regular food pantry clients to compare the influence of a behavioral economic intervention to promote healthier food choices delivered via a web-based ordering platform to usual care (control group). At this pantry, clients are assigned points to “buy” food and place their orders via a touchscreen-based computer ordering platform. We will implement an intervention that employs several behavioral economic strategies and compare this intervention to the food pantry’s current online ordering system (usual care control group). Our behavioral economic intervention uses the following four strategies to promote healthier choices: 1) default settings; 2) healthy placement choice architecture; 3) simple and salient nutrition messaging; and 4) social norms messaging. Food pantry clients assigned to the intervention group will log into the usual food ordering platform, but it will pre-populate their shopping basket with several healthy, preferred items as the default (clients can opt to remove them). In addition, as clients navigate the website, a healthy placement choice architecture intervention will place the healthiest options at the top of the webpage for each food category. The third intervention component will display simple and salient traffic light labels to indicate foods that are more and less healthy along with salient messaging to highlight price discounts on healthier foods (e.g., “save 1.5 points by switching from white to brown rice”). The fourth intervention will display social norms messaging indicating the most commonly selected healthy products (e.g., over half of all customers order bananas when shopping here). We will compare how these two interventions influence: 1) the nutritional quality of food selected from the pantry based on transaction data; 2) dietary intake measured by fruit and vegetable biomarkers and food frequency questionnaires; and 3) objectively measured weight, blood pressure, and HbA1c levels. !

项目概要 肥胖、不健康的饮食习惯和食品不安全是主要的公共卫生问题， 尤其影响生活在贫困中的个人，这些机构为贫困人口提供免费食物。 有需要的人对促进健康选择越来越感兴趣，但很少有严格的研究表明 经过测试的低成本行为干预措施，鼓励食品储藏室选择健康食品 该提案的总体目标是进行为期 1 年的随机对照试验。 在 500 名食品储藏室的常客中比较行为经济学的影响 通过基于网络的订购平台提供的干预措施，以促进更健康的食物选择 常规护理（对照组） 在这个食品储藏室，客户被分配点来“购买”食物和地点。 他们通过基于触摸屏的计算机订购平台订购。 采用多种行为经济策略的干预措施并比较这种干预措施 到食品储藏室当前的在线订购系统（常规护理对照组）。 经济干预使用以下四种策略来促进更健康的选择：1）默认 设置；2）健康的布局选择架构；3）简单而显着的营养信息； 4) 分配到干预组的食品储藏室客户将记录社会规范消息。 进入通常的食品订购平台，但它会在他们的购物篮中预先填充一些 健康的、首选的项目作为默认值（客户可以选择删除它们）。 浏览网站，健康的放置选择架构干预将放置 每个食物类别的网页顶部都有最健康的选项。 组件将显示简单而显着的交通灯标签，以指示更多和更丰富的食物 不太健康，但带有突出的信息，以强调健康食品的价格折扣（例如， 将显示“从白米改为糙米可节省 1.5 分”）。 社会规范信息表明最常选择的健康产品（例如，超过一半 的顾客在这里购物时订购香蕉）我们将比较这两者的情况。 干扰影响： 1）从食品储藏室挑选的食品的营养质量依据 2）通过水果和蔬菜生物标志物和食物测量的饮食摄入量； 频率问卷；3) 客观测量体重、血压和 HbA1c 水平。 ！
