Home Food Environment Measurement Methods

描述(由调查人员提供)：食物选择和体重指数是糖尿病、心血管疾病和某些癌症等慢性疾病的重要媒介。邻居和家庭的食物环境都可能在影响个人的食物选择和体重指数方面发挥重要作用。然而，目前对这些结构的衡量是不发达和不精确的。此外，很少有研究收集个人、家庭和邻里层面的数据。大多数现有的研究都是横断面的，因此它们提供关于因果影响的信息的能力有限。这项拟议的研究将分析和增强作为家庭层面社区干预措施的一部分收集的现有数据，以防止体重增加。主要目的是开发邻居和家庭食品环境的衡量标准，并详细检查这些衡量标准的公制属性。第二个目标是开发一系列多水平的模型，以更好地了解家庭食物环境、家庭人口统计和社区零售食物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邻里食品环境的衡量标准。本课程将研究与食物选择和体重指数等重要个体水平结果之间的关系。

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.
