DESCRIPTION (provided by applicant) The recent dramatic increase in obesity has occurred more rapidly than can reasonably be explained by a change in physiological or genetic makeup of the individual, pointing to changes in the environment as likely contributors. The design and architecture of the physical environments where people live and work, the built environment has been suspected as a contributor to obesity by promoting a reduction in activity and an increase in food intake. The existing research, though, has investigated the nature of the overall built environment in which the individual resides and relates the characteristics of that environment to the individual's reported overall behavior. It does not relate actual environmental features to actual real time behaviors. Also, the nature of the environment is confounded with the nature of the individuals who choose to occupy the environment, often differing in socioeconomic status, race etc. Finally prior research has investigated environments that do not have a large range of variation. The proposed project is an exploratory study to develop the methodology and analytic techniques to address the relationship of the built environment to energy balance. The developed methods will then be employed to investigate the real time relationships of actual behavior to the characteristics of the exact environment in which the behavior occurs. The project will develop a method for assessing intake and activity empirically with triaxial accelerometers and 7-day diet diaries while monitoring the individuals' exact positions with Global Positioning System (GPS) data logging receivers. Geographical Information System (GIS) data bases will be accessed to establish the characteristics of the built environment at the point of the actual behavior. The project will develop a method to identify how the characteristics of the built environment are related to intake and activity. It will develop a method to ascertain how the same individual responds to different environmental characteristics. It will develop a method to ascertain how characteristics of the individual interact with the built environment to affect intake and activity. It will begin to explore activity, intake and built environment relationships in a wide range of environments. The epidemic of obesity is posing a significant danger to public health. By identifying how the built environment may be contributing to intake and activity, the proposed research should lead to a better understanding of the causes of obesity and routes for prevention and treatment.

描述（由申请人提供） 肥胖症最近发生的急剧增长比通过对个体的生理或遗传组成的变化进行了更快的速度，这表明环境的变化可能是贡献者的可能性。 人们生活和工作的物理环境的设计和建筑，通过促进活动减少和食物摄入量的增加，被怀疑是肥胖的贡献。 不过，现有的研究调查了个人居住的整体建筑环境的性质，并将环境的特征与个人报告的整体行为联系起来。 它没有将实际环境特征与实际实时行为联系起来。 同样，环境的性质与选择占领环境的个人的本质相混淆，社会经济地位，种族等通常有所不同。最后，先前的研究调查了没有差异范围差异的环境。 拟议的项目是一项探索性研究，旨在开发方法和分析技术，以解决建筑环境与能量平衡的关系。 然后，将采用开发的方法研究实际行为与行为发生的确切环境的特征的实时关系。 该项目将开发一种用三轴加速度计和7天饮食日记在经验上评估摄入量和活动的方法，同时使用全球定位系统（GPS）数据记录接收器监测个人的确切位置。 将访问地理信息系统（GIS）数据库，以在实际行为时期建立构建环境的特征。 该项目将开发一种方法来确定建筑环境的特征与摄入和活动的关系。 它将开发一种方法来确定同一个人如何响应不同的环境特征。 它将开发一种方法来确定个人特征如何与建筑环境相互作用以影响摄入和活动。 它将开始在各种环境中探索活动，摄入和建立环境关系。 肥胖的流行对公共卫生构成了重大危险。 通过确定建筑环境如何有助于摄入和活动，拟议的研究应更好地了解肥胖和预防和治疗途径的原因。
