Home Food Environment Measurement Methods

描述（由研究者提供）：食物选择和体重指数是慢性疾病（如糖尿病、心血管疾病和某些癌症）的重要介质。邻里和家庭食物环境都可能在影响个人食物选择和体重指数方面发挥重要作用。然而，目前的措施，这些结构是欠发达和不精确的。此外，很少有研究收集个人、家庭和社区层面的数据。大多数现有的研究是横断面的，因此在提供因果影响信息方面能力有限。拟议的研究将分析和增加现有的数据收集作为家庭一级的社区干预的一部分，以预防体重增加。主要目的是制定措施的邻里和家庭食品环境，并详细研究这些措施的度量属性。第二个目标是开发一系列多层次模型，以更好地了解家庭食品环境，家庭人口统计学和社区零售食品供应对个人食物选择和体重变化的影响。公共卫生相关性：拟议的研究将制定家庭和社区食品环境的措施。与重要的个人水平的结果，如食物选择和体重指数的关联将被检查。

DESCRIPTION (provided by investigator): Food choices and body mass index are important mediators of chronic diseases such as diabetes, cardiovascular disease and certain cancers. Both the neighborhood and the home food environment may play an important role in influencing individual food choices and body mass index. However, current measures of these constructs are underdeveloped and imprecise. Furthermore, few studies have collected data at the individual, home and neighborhood levels. Most of the available studies are cross- sectional and are therefore limited in their ability to provide information about causal influences. The proposed research will analyze and augment existing data collected as part of a household-level community intervention for weight gain prevention. The primary aim is to develop measures of the neighborhood and home food environment, and to examine the metric properties of these measures in detail. The secondary aim is to develop a series of multi-level models to better understand the influences of the home food environment, household demographics, and neighborhood retail food availability on individual food choices and change in body weight. PUBLIC HEALTH RELEVANCE: The proposed research will develop measures of the home and neighborhood food environment. Associations with important individual level outcomes such as food choices and body mass index will be examined.
