Community Influences on NHANES Diet and Physical Activity

描述(由申请人提供)：这份新的R01申请是为了响应PA-08-192地理和背景对能量平衡相关健康行为的影响而提交的。该项目建议使用国家健康和营养检查研究(NHANES)对肥胖相关背景和结果(即与肥胖相关的行为)和影响(即与肥胖相关的终点)进行多层次、纵向的评估。国家卫生统计中心最近向经批准的研究人员提供了地理参考NHANES以供分析。作为经批准的研究，该项目围绕社区和社区层面的各种食物和身体活动环境进行组织，以供自1999年以来进行并可获得的五项调查(即NHANES 1999-2000、2001-2002、2003-2004、2005-2006、2007-2008)中的连续NHANES参与者使用。通过在各自的社区(例如人口普查区域)和政治管辖区(例如人口普查地点)内定位NHANES调查受访者，并根据食物和体育活动环境来描述这些位置，可以利用NHANES的许多优势来评估肥胖文献中的一些突出问题。

DESCRIPTION (provided by applicant): This new R01 application is submitted in response to PA-08-192 Geographic and Contextual Influences on Energy Balance-Related Health Behaviors. The project proposes multilevel, longitudinal evaluation of obesity related contexts and resulting outcomes (i.e., obesity related behaviors) and impacts (i.e., obesity related endpoints) using the National Health and Nutrition Examination Study (NHANES). The National Center for Health Statistics has recently made available for analysis the georeferenced NHANES to approved researchers. As approved research, the project is organized around characterizing the various food and physical activity environments at the neighborhood and community levels for Continuous NHANES participants in the five surveys conducted and available since 1999 (i.e., NHANES 1999-2000, 2001-2002, 2003-2004, 2005-2006, 2007-2008). By locating NHANES survey respondents within their respective neighborhoods (e.g., census tracts) and political jurisdictions (e.g., census place) and characterizing these locations in terms of the food and physical activity environments the many strengths of the NHANES can be brought to bear to evaluate a number of outstanding issues in the obesity literature.
