DESCRIPTION (provided by applicant): Obesity and stress are highly comorbid and both increase risk for cardiovascular disease (CVD). Stress is associated with disinhibited eating, junk food consumption and low consumption of produce and whole grains. Both stress and stress-induced eating are not only associated with obesity but also predict worst outcomes in lifestyle interventions. In addition to diet and physical activity, both stress and stress-induced eating should be targeted in interventions obese adults to maximize weight loss and CVD risk reduction; however, this makes for an intensive intervention. Technology could be leveraged to reduce intervention burden while still addressing more complicated patient issues by collecting and compiling patient data to inform clinician decision making and directly delivering intervention strategies. The purpose of this proposal is to develop and test the feasibility and proof-of-concept of RELAX Application Suite (AS), a mobile-, and cloud- and web-based companion to a lifestyle intervention for obese individuals. RELAX-AS includes RELAX-app and RELAX-web. RELAX-app is a patient-facing mobile application that will be linked to Microsoft Health Vault, a cloud-based platform that allows for secure access of health data online. RELAX-app will include self-monitoring (diet, exercise, stress, stress-induced eating); automated feedback via easy-to-interpret visual displays and feedback reports on the amount, timing, context, and relationship between target behaviors; and self-guided stress management features that are prompted when stress ratings are elevated. RELAX-web is a web-based application for clinicians to access the patient's information in the form of easily digestible visual displays and feedback reports to increase the efficiency of their counseling. Our goal is to use RELAX-AS to create an intervention delivery model that reduces both weight and stress with half the visits of traditional lifestyle interventions. We propose a 3-year study that includes 3 phases: Requirements Gathering/Development, Usability Testing/Pre-Pilot, and Pilot. Requirements Gathering/Development work will focus on the iterative development of visual displays, feedback messages, and mobile-delivered stress reduction strategies among users and clinicians. In the Usability Testing/Pre-pilot phase we will examine usability of RELAX-AS in both members of the target population and clinicians using an abbreviated 4-week pre-pilot intervention. In the Pilot phase, we will randomize obese adults to 3 conditions: RELAX-AS, a generic diet/exercise application system, or no technology. All conditions will receive brief weight loss counseling. Feasibility outcomes will be usage of app features, acceptability, adherence, clinician time, burden, retention, time and cost. Exploratory outcomes include changes in weight, stress, and stress-induced eating. This work will prepare us for a 2-arm efficacy trial comparing RELAX-AS with a brief lifestyle intervention to a brief lifestyle intervention alone on weight, stress, and stress eating.

描述（由申请人提供）：肥胖和压力是高度共存的，并且都会增加心血管疾病（CVD）的风险。压力与饮食失调、垃圾食品消费以及农产品和全谷物消费量低有关。压力和压力引起的饮食不仅与肥胖有关，而且还预示着生活方式干预的最坏结果。除了饮食和身体活动外，肥胖成年人的干预措施还应针对压力和压力引起的饮食，以最大限度地减轻体重和降低心血管疾病风险；然而，这需要进行密集干预。可以利用技术来减轻干预负担，同时通过收集和编译患者数据来为临床医生决策提供信息并直接提供干预来解决更复杂的患者问题 策略。该提案的目的是开发和测试 RELAX 应用程序套件 (AS) 的可行性和概念验证，这是一个基于移动、云和网络的伴侣，用于肥胖个体的生活方式干预。 RELAX-AS 包括 RELAX-app 和 RELAX-web。 RELAX-app 是一款面向患者的移动应用程序，将链接到 Microsoft Health Vault，这是一个基于云的平台，允许安全地在线访问健康数据。 RELAX-应用程序将包括自我监控（饮食、锻炼、压力、压力引起的饮食）；通过易于解释的视觉显示和关于目标行为之间的数量、时间、背景和关系的反馈报告来自动反馈；以及当压力等级升高时会提示的自我引导压力管理功能。 RELAX-web 是一款基于网络的应用程序，临床医生可以通过易于理解的视觉显示和形式访问患者信息 反馈报告以提高咨询效率。我们的目标是使用 RELAX-AS 创建一种干预实施模式，以传统生活方式干预措施的一半来减轻体重和压力。我们提出为期 3 年的研究，包括 3 个阶段：需求收集/开发、可用性测试/预试点和试点。需求收集/开发工作将侧重于视觉显示、反馈消息以及用户和临床医生之间移动传输的减压策略的迭代开发。在可用性测试/预试点阶段，我们将使用简短的 4 周预试点干预来检查 RELAX-AS 在目标人群和临床医生中的可用性。在试点阶段，我们将肥胖成年人随机分为 3 种情况：RELAX-AS、通用饮食/运动应用系统或无技术。所有情况都将接受简短的减肥咨询。可行性结果将包括应用程序功能的使用、可接受性、依从性、临床医生时间、负担、保留、时间和成本。探索性结果包括体重、压力和压力引起的饮食的变化。这项工作将为我们进行 2 组疗效试验做好准备，该试验将 RELAX-AS 与简短的生活方式干预与单独的简短生活方式干预对体重、压力和压力饮食进行比较。
