Home Food Environment Measurement Methods

描述（研究者提供）：食物选择和身体质量指数是糖尿病、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，目前对这些结构的测量是不发达和不精确的。此外，很少有研究收集了个人、家庭和社区层面的数据。大多数现有的研究都是横断面的，因此在提供因果影响的信息方面能力有限。拟议的研究将分析和扩大现有的数据收集，作为家庭一级社区干预体重增加预防的一部分。主要目的是制定邻里和家庭食品环境的措施，并详细检查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，以更好地理解家庭食品环境、家庭人口统计和社区零售食品可得性对个人食品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。与重要的个人水平结果，如食物选择和体重指数的关系将被检查。

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.
