项目摘要

DESCRIPTION (provided by applicant): The prevalence of overweight and obesity among children and adolescents has been increasing dramatically with low-income and some racial/ethnic minority populations being at highest risk. Rising obesity rates and socioeconomic disparities in obesity stem from social and environmental factors that need to be understood and modified for effective prevention. In this project, we propose to follow a cohort of 20,000 children through elementary school, a period when demographic disparities in obesity manifest themselves, to study their physical development, health behaviors, and the relationship of these outcomes and behaviors to the food and physical activity environments in their residential and school neighborhoods. Our specific aims are as follows: 1. Describe how the food and physical activity environments around residences and schools differ for children from different socioeconomic and racial/ethnic groups. 2. Describe how the food and physical activity environments inside elementary schools differ for children from different socioeconomic and racial/ethnic groups. 3. Analyze the relationship between food and physical activity environments and health behaviors, by socioeconomic and racial/ethnic groups. 4. Analyze the contribution of food and physical activity environments in the development of disparities in body mass index (BMI) in children from kindergarten through 5th (and for some analyses 8th) grade. PUBLIC HEALTH RELEVANCE: School and residential environments are likely to shape children's health behaviors, but their contributions to excess weight gain are unknown. This project tries to identify environmental factors of excess weight gain during elementary school years, which includes the age where sociodemographic disparities in overweight begin to manifest themselves. This is a necessary task before considering whether proposed interventions and policy changes are promising or likely to lead down a blind alley.

描述（由申请人提供）：儿童和青少年超重和肥胖的患病率随着低收入和一些种族/族裔少数族裔的风险最高而急剧增加。肥胖症的肥胖率和社会经济差异的上升源于需要理解和修改以有效预防的社会和环境因素。在这个项目中，我们建议在小学上跟随20,000名儿童组成的队列，在这个时期，肥胖症的人口差异表现出来，研究他们的身体发展，健康行为以及这些结果和行为与住宅和学校社区中食品和体育活动环境的关系。我们的具体目的如下：1。描述住所和学校周围的食物和体育锻炼环境与不同的社会经济和种族/种族群体的儿童不同。 2.描述小学内部的食物和体育活动环境与不同的社会经济和种族/族裔的儿童有何不同。 3。通过社会经济和种族/族裔分析食品与体育活动环境与健康行为之间的关系。 4。分析食品和体育活动环境在幼儿园到5年级（以及某些分析8年级）的儿童体重指数（BMI）差异发展的贡献。公共卫生相关性：学校和住宅环境可能会塑造儿童的健康行为，但是他们对体重增加的贡献却未知。该项目试图确定小学期间体重增加过多的环境因素，其中包括超重社会人口统计学差异开始显现的年龄。在考虑拟议的干预措施和政策变更是否有希望或可能导致盲人巷的情况下，这是一项必要的任务。
