The Effect of Corner Store Makeovers on Store Patrons and Nearby Corner Stores

描述（由申请人提供）：有证据表明，超重和肥胖的结果受到食品环境的影响，或者受到人们生活、工作和上学场所周围健康和不健康食品销售点分布的影响。改善低收入和少数族裔社区食品环境的一种新方法是“街角商店改造”，它涉及与当地街角商店合作，扩大新鲜水果、新鲜蔬菜和其他健康食品的供应。“洛杉矶东部的街角商店改造：改善健康食品的获取”是nhlbi资助的一项研究项目，目前由加州大学洛杉矶分校/南加州大学人口健康和健康差异中心（CPHHD）进行。该项目正在与东洛杉矶的四家干预店合作，以大大扩大其新鲜农产品和其他健康食品的库存，并重新配置每家店的布局，使健康食品更加突出，在视觉上更具吸引力。此外，该项目正在与当地高中的青年合作，开展一项社区驱动的、具有文化竞争力的社会营销活动，推广健康食品和改造商店。在本研究中，我建议通过评估其对：(1)商店顾客的影响，以及(2)靠近干预商店的街角商店的影响，来补充现有的街角商店改造项目的评估策略。为了评估干预措施对商店顾客的影响，我建议与中心训练有素的学生和工作人员合作，在四家干预店和四家比较店与顾客进行前/后访谈。本评价研究将有助于我们评估街角店改造对顾客营养知识和对商店态度的影响，并确定街角店改造是否改变了他们购买和消费食品的健康性。为了评估干预对附近街角商店的影响，我建议对每个干预店和比较店附近的五家街角商店的健康食品库存和店内广告进行纵向研究。由于街角商店改造项目的社会营销活动和大量媒体报道，我相信在干预商店周围的社区对健康食品的需求将大幅增加。因此，附近的商店可能会有动力做出自己的健康改变。每一项补充评估都将极大地增加关于街角商店改造战略有效性的非常有限的经验证据。

DESCRIPTION (provided by applicant): Evidence suggests that overweight and obesity outcomes are affected by the food environment, or the distribution of healthy and unhealthy food outlets around the places where people live, work, and go to school. An emerging approach to improving the food environment in low income and minority communities is the 'corner store makeover,' which involves partnering with local corner stores to expand access to fresh fruit, fresh vegetables, and other healthy food. "Corner Store Makeovers in East Los Angeles: Improving Healthy Food Access" is an NHLBI-funded research project that is currently being conducted by the UCLA/USC Center for Population Health and Health Disparities (CPHHD). The project is working with four intervention stores in East L.A. to greatly expand their inventories of fresh produce and other healthy food, as well as to reconfigure each store's layout to make healthy food more prominent and visually appealing. In addition, the project is working with youth from local high schools to develop a community-driven and culturally competent social marketing campaign that promotes healthy food and the made over stores. In this study, I propose to complement the existing evaluation strategy of the corner store makeovers project by evaluating its effects on: 1) store patrons, and 2) corner stores that are nearby intervention stores. To assess the effects of the intervention on store patrons, I propose to work with trained students and staff at CPHHD to conduct pre/post- interviews with patrons at four intervention and four comparison stores. This evaluation study will help us to assess the effect of corner store makeovers on patrons' nutrition knowledge and attitudes towards the store and to determine if corner store makeovers change the healthfulness of their food purchasing and consumption. To evaluate the effect of the intervention on nearby corner stores, I propose to conduct a longitudinal study of healthy food inventories and in-store advertisements at five corner stores nearby each of the intervention and comparison stores. Due to the social marketing campaign and substantial media coverage of the corner store makeovers project, I believe that demand for healthy food will increase substantially in the neighborhoods surrounding intervention stores. As a result, nearby stores may be motivated to make their own healthy changes. Each of these supplemental evaluation components will greatly add to the very limited empirical evidence regarding the effectiveness of the corner store makeovers strategy. PUBLIC HEALTH RELEVANCE: An emerging approach to increasing access to healthy food in low income and minority communities is the 'corner store makeover,' which involves partnering with local corner stores to expand access to fresh fruit, fresh vegetables, and other healthy food. I propose to evaluate how a corner store makeover project in East Los Angeles affects store patrons and nearby corner stores. This study will add to the very limited empirical evidence regarding the effectiveness of the corner store makeovers strategy and will be the first to evaluate its effectiveness in a predominantly Latino community.
