PROJECT ABSTRACT Unhealthy diet and obesity are major causes of cardiovascular disease (CVD). Emerging adults (ages 18-25) are a crucial group to target with CVD prevention interventions because they have lower dietary quality and experience more rapid weight gain than adults in middle and older adulthood. Moreover, emerging adulthood is distinct developmental period during which lifelong eating behaviors and CVD risk trajectories are largely established. Communication interventions, particularly those appealing to emerging adults’ strong interest in both environmental sustainability and personal health, are a promising but understudied strategy for addressing unhealthy diet in this age group. The goal of the proposed research is to design and rigorously evaluate a communication intervention to reduce dietary risk factors for CVD among emerging adults. The first aim is to identify specific dietary substitutions that emerging adults can readily make to reduce their CVD risk and dietary environmental harms. To identify these substitutions, I will analyze dietary intake data from the National Health and Nutrition Examination Surveys linked to a comprehensive database of foods’ greenhouse gas emissions. The second aim is to develop and optimize health and environmental messages about these dietary substitutions. I will develop candidate messages, pre-test them in qualitative focus groups, then use a randomized factorial experiment with 800 emerging adults to identify the most effective message strategies. The third aim is to evaluate the impact of the messaging interventions on healthfulness of food purchases. In a longitudinal randomized controlled trial, I will assign 500 emerging adults to 1 of 4 conditions: control (no messages), health, environmental, or health + environmental messages. Participants will simulate five weekly shopping trips in an online grocery store with their assigned messages prominently displayed. I will evaluate each messaging interventions’ initial, sustained, and overall impacts on purchase healthfulness and identify the most effective type of message. This research will further NHLBI’s strategic goal of preventing CVD and NIH Nutrition Research Objective 2-6 to leverage behavioral science to initiate and sustain healthy eating. Further, this award will help me achieve my long-term career goal of becoming an independent investigator focused on effective, scalable CVD prevention interventions for emerging adults. With support from this K01, I will build on my expertise in nutrition policy to fill critical training gaps in: 1) the CVD and environmental impacts of food, 2) communication interventions for emerging adults, 3) mixed methods, and 4) advanced analytic techniques for longitudinal studies. My detailed training plan includes tutorials with my interdisciplinary mentorship team at the Harvard TH Chan School of Public Health, formal coursework, hands-on research activities, and participation in conferences, workshops, and seminars. The K01 will provide me with the expertise and preliminary data needed to become an independent researcher successfully competing for R01 funding in this area.

项目摘要 不健康的饮食和肥胖是心血管疾病（CVD）的主要原因。新兴成年人（18-25岁） 是针对CVD预防干预措施的关键群体，因为它们具有较低的饮食质量和 在成年期间，体重增加比成年人更快。而且，新兴的成年是 终身饮食行为和CVD风险轨迹在很大程度上是不同的发展时期 已确立的。沟通干预措施，尤其是那些似乎是新兴成年人对 环境可持续性和个人健康都是有希望的，但对 解决这个年龄段的不健康饮食。拟议的研究的目的是设计和严格设计 评估沟通干预措施，以减少新兴成年人中CVD的饮食危险因素。第一个 目的是确定新兴成年人可以轻松降低CVD风险的特定饮食替代品 和饮食环境危害。为了确定这些替代，我将分析来自 国家健康和营养检查调查与食品温室的全面数据库相关联 气体排放。第二个目的是开发和优化有关这些的健康和环境信息 饮食替代。我将开发候选消息，以定性焦点小组进行测试，然后使用 与800名新兴成年人进行随机阶乘实验，以识别最有效的消息策略。 第三个目的是评估消息干预措施对食物购买健康的影响。在 纵向随机对照试验，我将分配500名新兴成年人为4个条件中的1个：对照（否 消息），健康，环境或健康 +环境信息。参与者将每周模拟五个 在一家在线杂货店的购物旅行，其分配的消息突出显示。我会评估 每种消息干预措施的最初，持续和整体对购买健康的影响，并确定 最有效的消息类型。这项研究将进一步防止CVD和NIH的战略目标 营养研究目标2-6利用行为科学来启动和维持健康的饮食。更远， 该奖项将有助于我实现成为专注于专注于的独立调查员的长期职业目标 针对新兴成年人的有效，可扩展的CVD预防干预措施。在此K01的支持下，我将继续 我在营养政策方面填补关键培训空白的专业知识：1）食品的CVD和环境影响，2） 新兴成年人的交流干预措施，3）混合方法和4）高级分析技术 纵向研究。我的详细培训计划包括与我的跨学科指导团队的教程 哈佛大学公共卫生学院，正式课程，动手研究活动和参与 在会议，讲习班和半小伙子中。 K01将为我提供专业知识和初步数据 需要成为一名独立研究人员，成功地在该领域争夺R01资金。
