Corner Store Makeovers in East Los Angeles: Improving Healthy Food Access

加利福尼亚州的东洛杉矶一直被描述为“食物沙漠”，那里的居民很难接触到 综合杂货店和推荐的食物，以保持健康和均衡的饮食。不良的饮食习惯 造成严重的慢性疾病差异。东洛杉矶有超过96%的拉丁裔居民，其中大多数 生活在贫困之中。为了解决食品获取方面的差距，我们将改造街角商店，这是一个常见的食品场所 在这个社区购物。我们将测试街角商店改造在东洛杉矶是否可行，以及 商店改造是否有助于更健康的社区。使用生态和社区为基础的 参与式的方式，我们将与四个角落的店主合作，加强营销实践，储存食物 质量和销售，以及社区参与。对于这些商店，当地的高中青年将创造和 为社区成员分发有关购买健康食品的宣传和教育材料， 准备和进食。四个未转换的角落凝视和他们的邻居将作为对比 组。该项目的框架将街角商店概念化为可支持的社区资产 居民健康食品购买、制备和饮食行为的调查以下四个目标指导着 研究：1)需要哪些因素来说服和使街角店主改装他们的店铺；2) 在资源贫乏的社区营销和推广角落商店的最佳做法是什么；3)因素是什么 与角落商店改造的维护和可持续性有关；以及4)角落有什么影响 门店改建对社区居民健康行为的影响。形成性研究和评估将 用于评估项目的可行性。项目监测将用于评估研究的实施情况。多个 将使用案例研究方法来评估街角商店的采用和维护。结果评估将使用 按分层重复横断面调查的准试验性对照分组设计 包含改建和控制街角商店的社区。我们将对1000名社区居民进行调查， 两个不同的浪潮，来评估结果。研究街角商店转换的工作原理及其影响 关于社区的研究是当前公共卫生差距和干预研究中一个未被充分研究的方面。

East Los Angeles, California has been characterized as a "food desert," where residents have poor access to comprehensive grocery stores and foods recommended for a healthful and balanced diet. Poor dietary practice contributes to significant chronic disease disparities. East L.A. has over 96% Latino residents, of whom, most live in poverty. To address food access disparities, we will convert corner stores, a common venue for food purchasing in this community. We will test whether corner store conversions are feasible in East L.A. and also whether store conversions contribute to healthier communities. Using an ecological and community-based participatory approach, we will work with four corner store owners to enhance marketing practices, store food quality and sales, and community involvement. For these stores, local high school youth will create and distribute outreach and education materials for community members about healthy food purchasing, preparation and eating. Four unconverted corner stares and their neighborhoods will serve as comparison groups. The project's framework conceptualizes the corner store as a neighborhood asset that can support healthy food purchasing, preparation and eating behaviors among residents. The following four aims guide the research: 1) what factors are necessary to persuade and enable corner store owners to convert their stores; 2) what are the best practices to market and promote corner stores in resource poor communities; 3) what factors are related to the maintenance and sustainability of corner store conversions; and 4) what impact do corner store conversions have on the health behaviors of community residents. Formative research and evaluation will be used to assess project feasibility. Program monitoring will be used to assess study implementation. A multiple case study approach will be used to assess corner store adoption and maintenance. Outcome evaluation will use a quasi-experimental, comparison groups design with repeated cross-sectional surveys stratified by neighborhoods containing converted and control corner stores. We will survey 1,000 community residents, in two different waves, to assess outcomes. Studying how corner store conversions work and the impact they have on communities is an understudied facet of current public health disparities and intervention research.
