项目摘要

Background and significance: Obesity rates remain high, despite nationwide declines and plateaus in the overall prevalence of obesity among some groups. Crucially, Black and Latino children have higher obesity rates than non-Hispanic Whites (hereafter “disparities”). Effective strategies to reduce child obesity and disparities could significantly contribute to population health improvements and reductions in racial/ethnic health disparities. Nutrition policies—those that regulate the nutritional content of foods and beverages in schools, including the so-called “competitive” foods because they are sold separately from school meals— could play a key role in the primary prevention of obesity and related chronic diseases. The effect of nutrition policies however, can be strengthened or weakened by the community food environment near schools (e.g., through children’s access, purchases and consumption of unhealthy foods). No studies have yet examined the combined influences of multiple nutrition policies and community food environments on child obesity and disparities. Objectives: This quasi-experimental study is responsive to the NIH Obesity Strategic Plan and proposes to: (1) determine the obesity effects of the California nutrition policy improving and limiting access to “competitive” foods/beverages together with the recent federal policy to improve school meal nutrition standards; and (2) investigate whether community food environments modify the effect nutrition policies on obesity and related disparities. Innovation. The study: (a) improves causal inferences about the effects of nutrition policies on obesity and disparities using rigorous, complementary methods (interrupted time series design, propensity scores, and latent class analysis, GIS); (b) simultaneously investigates the obesity effects of the nutrition policies and the surrounding school food environment; and (c) uses a longitudinal, robust (>16 million) population-based data containing objective individual-level BMI measures of diverse children (51% Latino, 6% Black, 33% White, 8% Asian) linked with the community food environments of all the public schools to which children attended in California from 2001 to 2017.

背景和意义：尽管全国范围内肥胖率有所下降，但肥胖率仍然很高肥胖症在某些群体中的总体流行率。至关重要的是，黑人和拉丁裔儿童的肥胖率更高，与非西班牙裔白人相比（以下简称“差异”）。减少儿童肥胖的有效战略，差异可以大大有助于改善人口健康和减少种族/族裔歧视，健康差距。营养政策-那些规定食品和饮料营养成分的政策，学校，包括所谓的“竞争”食品，因为它们是分开出售的学校餐- 可以在肥胖症和相关慢性疾病的初级预防中发挥关键作用。营养的影响然而，学校附近的社区食品环境可以加强或削弱政策（例如，通过儿童获得、购买和消费不健康食品）。目前还没有研究对多种营养政策和社区食物环境对儿童肥胖的综合影响，差距。目的：这项准实验性研究是对NIH肥胖战略计划的响应，建议：（1）确定加州营养政策对肥胖的影响，改善和限制获得 “有竞争力的”食品/饮料以及最近的联邦政策，以改善学校膳食营养标准;（2）调查社区食品环境是否改变营养政策对肥胖和相关的不平等。创新该研究：（a）改进了关于以下影响的因果推理：采用严格、互补的方法（间断时间序列）制定关于肥胖和差距的营养政策设计、倾向评分和潜在类别分析，GIS）;（B）同时调查肥胖的影响营养政策和周围的学校食品环境;以及（c）使用纵向的，稳健的（>16 基于人口的数据，包含不同儿童的客观个人水平BMI测量（51%）拉丁裔，6%黑人，33%白色，8%亚洲人）与所有公立学校的社区食品环境有关加州2001年至2017年儿童参加的活动。
