项目摘要

Abstract Dietary intake is a powerful, modifiable factor that influences cancer risk. Unfortunately, most adults in the U.S. find it difficult to adhere to dietary guidelines for cancer prevention. One promising pathway for improving dietary adherence is to target grocery shopping habits, i.e., foods purchased for consumption at home. Two- thirds of daily food intake is sourced from or eaten in the home, so improving the quality of the home food environment should improve overall diet quality. When healthy foods are purchased and unhealthy foods are not, minimal self-control is needed to make healthy eating choices in the home. At the point of purchase, it is difficult to resist the temptation of palatable foods, but interventions might facilitate healthy choices by a) promoting dietary goal salience in real-time while grocery shopping, b) enhancing motivation to make and sustain changes to the diet, and c) increasing household support and accountability for healthy food purchasing. At this stage of research, methodical testing of intervention components that can change food purchase behaviors is needed, in order to craft an mHealth intervention package that is feasible, acceptable, and optimized for efficacy and scalability. The proposed study will enroll adults (N = 64) who have low adherence to cancer prevention dietary recommendations. All participants will attend a 3-hour nutrition education workshop. For 6 months following the workshop, all participants will receive text notifications that provide tailored reminders and recommendations for food purchasing. The study will use a factorial design to experimentally test four additional intervention components and examine their feasibility, acceptability, and effect on food purchases and dietary intake at 3 and 6 months. (Each component is randomly assigned to be activated for 50% of participants.) The four components to be tested are: 1) Location-triggered text notifications: Reminders and recommendations for food purchases are delivered “just-in-time,” when arriving at grocery shopping locations, to enhance goal salience. 2) Reflections on the benefits of change: To enhance motivation, content is added to messages to encourage reflection on the anticipated benefits of healthy eating. 3) Coach monitoring: Food purchases are automatically monitored by a coach (through a system that collects item-level store data) who sends personalized post-purchase messages designed to enhance supportive accountability and thus motivation. 4) Household text: Other adults in the household receive messages designed to elicit support for healthy food purchasing and provide another source of supportive accountability. The preliminary aim of the study is to assess feasibility and acceptability of the intervention components. The primary aim of the study is to quantify the effect of each intervention component, individually and in combination, on grocery store food purchases (objectively assessed with store data), and dietary intake (assessed with 24-hour food recalls). Mediation analyses also will be conducted. The overarching goal of this project is to optimize this mHealth intervention, which can be tested in the future in a fully powered clinical trial.

抽象的不幸的是，饮食摄入量是影响癌症风险的一个强大的、可改变的因素。发现很难遵守预防癌症的饮食指南，这是一种有希望的改善途径。饮食依从性是针对杂货购物习惯，即购买在家消费的食物。每日食物摄入量的三分之一来自或在家中食用，因此提高家庭食物的质量当购买健康食品和购买不健康食品时，环境应该改善整体饮食质量。不是，在购买时需要最低限度的自我控制才能在家中做出健康的饮食选择。很难抗拒美味食物的诱惑，但干预措施可能会通过以下方式促进健康选择：在杂货店购物时实时促进饮食目标的显着性，b）增强制定和实施饮食目标的动力持续改变饮食习惯，c) 增加家庭对健康食品的支持和责任在这个研究阶段，对可以改变食物的干预成分进行系统测试。需要购买行为，以便制定可行、可接受、并针对功效和可扩展性进行了优化。拟议的研究将招募患有低血压的成年人（N = 64）。遵守癌症预防饮食建议所有参与者都将参加 3 小时的营养课程。培训研讨会结束后 6 个月内，所有参与者都将收到短信通知：该研究将使用因子设计来提供定制的食品购买提醒和建议。实验测试四个额外的干预成分并检查其可行性、可接受性和对 3 个月和 6 个月时食物购买和饮食摄入的影响（每个成分被随机分配为。 50% 的参与者已激活。）要测试的四个组件是： 1) 位置触发的文本通知：食品购买提醒和建议会在到达时“及时”发送杂货购物地点，增强目标显着性 2) 反思变革的好处：增强。在消息中添加动机、内容，以鼓励反思健康饮食的预期好处。 3) 教练监控：食物购买由教练自动监控（通过收集数据的系统）商品级商店数据）谁发送个性化的购买后消息，旨在增强支持 4) 家庭文本：家庭中的其他成年人收到信息。旨在争取对健康食品购买的支持，并提供另一个支持性问责来源。该研究的初步目的是评估干预措施的可行性和可接受性。该研究的主要目的是量化每个干预措施的单独和整体效果杂货店食品购买（根据商店数据客观评估）和饮食摄入量的组合（还将进行 24 小时食品召回评估）。该项目的目的是优化这种移动医疗干预措施，该干预措施可以在未来通过全面的临床试验进行测试。
