DESCRIPTION (provided by applicant): In response to this funding opportunity announcement, our research group proposes to integrate the measurement of physical activity and food intake in "real-time" with newly developed methods in geospatial data management and analysis (Geographic Information Systems [GIS]), to address research questions related to energy balance and obesity. We introduce the multi-sensor board (MSB), cutting-edge, nonobtrusive technology capable of capturing diverse cues from a variety of sources during physical activity, including acceleration, elevation (barometric pressure), audio, light, and geophysical location. We will further exploit the unique movement and location sensing capabilities of the MSB to determine the location and frequency of eating episodes, and we will couple this information with a custom nutrition program that we will develop that will allow participants to record the type and amount of foods they consume at the time of eating. Thus, we will measure movement through space and time, under truly free-living conditions, to examine relationships between the major lifestyle behaviors related to energy balance and obesity -- namely physical activity and food intake -- and the built environment. The primary aims of this exploratory/developmental study are to develop and validate our novel approaches to measuring energy expenditure and energy intake. Another innovative aspect of the study is that this information will be integrated into a cellular telephone, which will be programmed to provide continuous feedback to the user in terms of increasing energy expenditure through increased physical activity and better utilization of locations and land uses that are associated with physical activity. The purpose of this third study aim is to explore the potential use of the integrated MSB-cellular telephone platform as a personal assistive device that could be used to monitor energy expenditure, energy intake, and energy balance in real-time to facilitate behavior changes favorable to weight loss or weight control.

描述（由申请人提供）： 为了响应这一资助机会的宣布，我们的研究小组建议将身体活动和食物摄入量的测量与地理空间数据管理和分析（地理信息系统[GIS]）的新开发方法“实时”相结合，以解决与能量平衡和肥胖相关的研究问题。我们介绍了多传感器板（MSB），这是一种尖端的非侵入性技术，能够在身体活动期间从各种来源捕获各种线索，包括加速度，海拔（气压），音频，光线和地球物理位置。我们将进一步利用MSB独特的运动和位置传感能力来确定进食事件的位置和频率，我们将把这些信息与我们将开发的定制营养计划结合起来，让参与者记录他们在进食时消耗的食物类型和数量。因此，我们将在真正自由的生活条件下，通过空间和时间来测量运动，以检查与能量平衡和肥胖相关的主要生活方式行为（即身体活动和食物摄入量）与建筑环境之间的关系。这项探索性/发展性研究的主要目的是开发和验证我们测量能量消耗和能量摄入的新方法。这项研究的另一个创新方面是，这一信息将被纳入一个移动电话，该移动电话将被编程为通过增加体力活动和更好地利用与体力活动有关的地点和土地使用来增加能量消耗方面向用户提供持续反馈。第三项研究的目的是探索集成MSB-蜂窝电话平台作为个人辅助设备的潜在用途，该设备可用于实时监测能量消耗、能量摄入和能量平衡，以促进有利于减肥或体重控制的行为变化。
