项目摘要
DESCRIPTION (provided by applicant): Wearable eButton for Evaluation of Energy Balance with Environmental Context and Behavior Overweight and obesity have become a wide spread epidemic affecting more than 60% of the population in the United States. A recent study indicates that the estimated direct and indirect costs of obesity to the U.S. economy are at least $215 billion annually. In the battle against obesity and related diseases, both the research and clinical communities require an accurate tool to measure people's energy intake and expenditure in real life. However, presently, the most utilized tool is still a questionnaire which is subjective and often inaccurate. The current state-of-the-art in diet and physical activity measurement has fallen far behind what the modern technology is able to provide. The field is mature for a substantial innovation. In this application, we propose the development of a new electronic device which has the potential to produce a technological quantum leap in the measurement of diet and physical activity. This button- like device, eButton, will be worn naturally on the chest using a pair of magnets or a pin. A new measurement concept based on the use of the wearable computer will be utilized in our device design. The eButton will contain a low-power, high-performance microprocessor running a simplified version of the LINUX operating system. It will contain numerous innovative designs, including an optical eating detector to monitor eating/drinking/smoking, two miniature cameras that produce a stereo vision to measure food portion size without depending on a reference card, an ear-based oximeter for measurement of heart rate and oxygen saturation, and an extrapolation formula to measure outdoor environment using the US environmental protection agency (EPA) database. eButton will store the multimedia data acquired by a variety of advanced miniature sensors in a flash memory within the device. It will also have a wireless link to a smart phone which will allow researchers to monitor the operating status of eButton remotely in real time. All sensors and function modules will be individually controlled by software to allow researchers to select among the available system resources for their particular needs. Despite the wide functionality of the device, eButton requires an extremely low user respondent burden. The research participant is required to do nothing more than turning on/off the device and recharging its battery at night. During our research, eButton and associated algorithms/software will be designed and constructed in our laboratory by an experienced team of electronic/software engineers based on an early version of the device developed under the NIH GEI diet and physical activity research program. Once eButton is constructed, we will implement a thorough validation process using human subjects to evaluate its accuracy in diet and physical activity assessment by comparing against the doubly-labeled water method as the gold standard.
PUBLIC HEALTH RELEVANCE: The primary goal of this research is to develop an advanced, button-like electronic device (eButton) that can be worn naturally on the chest. This device will contain a powerful microprocessor, a novel eating detector, a pair of cameras, and a variety of electronic sensors to automatically, jointly and objectively measure energy intake and expenditure, as well as environment and behavior related to diet and physical activity. All these measurements will be conducted with an extremely low respondent burden to research participants.
描述(由申请人提供):用于评估环境背景和行为的能量平衡的可穿戴eButton超重和肥胖已经成为影响美国60%以上人口的广泛流行病。最近的一项研究表明,肥胖对美国经济的直接和间接成本估计每年至少为2150亿美元。在与肥胖和相关疾病的斗争中,研究和临床社区都需要一种精确的工具来测量人们在真实的生活中的能量摄入和消耗。然而,目前,最常用的工具仍然是问卷,这是主观的,往往不准确。目前饮食和身体活动测量的最新技术已经远远落后于现代技术所能提供的。该领域已经成熟,可以进行实质性创新。 在这项应用中,我们提出了一种新的电子设备的开发,它有可能在饮食和身体活动的测量方面产生技术上的飞跃。这种类似纽扣的设备eButton将使用一对磁铁或别针自然地佩戴在胸部。一个新的测量概念的基础上使用的可穿戴计算机将在我们的设备设计中使用。eButton将包含一个低功耗、高性能的微处理器,运行简化版的Linux操作系统。它将包含许多创新的设计,包括一个光学进食探测器,以监测进食/饮水/吸烟,两个微型摄像机,产生立体视觉,以测量食物的份量大小,而不依赖于参考卡,一个基于耳朵的血氧计,用于测量心率和氧饱和度,以及一个外推公式,以测量户外环境使用美国环境保护署(EPA)数据库。eButton将把各种先进的微型传感器获取的多媒体数据存储在设备内的闪存中。它还将有一个与智能手机的无线连接,这将使研究人员能够真实的远程监控eButton的运行状态。所有传感器和功能模块将由软件单独控制,以允许研究人员根据其特定需求选择可用的系统资源。尽管该设备的功能广泛,但eButton需要极低的用户响应负担。研究参与者只需要在夜间打开/关闭设备并为其电池充电。 在我们的研究期间,eButton和相关算法/软件将由经验丰富的电子/软件工程师团队在我们的实验室中设计和构建,该团队基于NIH GEI饮食和身体活动研究计划下开发的早期版本。一旦eButton构建完成,我们将使用人类受试者实施全面的验证过程,通过与作为金标准的双标记水方法进行比较,评估其在饮食和身体活动评估中的准确性。
公共卫生关系:这项研究的主要目标是开发一种先进的按钮式电子设备(eButton),可以自然地佩戴在胸部。该设备将包含一个功能强大的微处理器,一个新颖的进食探测器,一对摄像头和各种电子传感器,以自动,联合和客观地测量能量摄入和支出,以及与饮食和身体活动相关的环境和行为。所有这些测量将在对研究参与者的应答负担极低的情况下进行。
