Improving access to healthy foods in low-income neighborhoods is a national priority. Our study evaluated the impact of opening a supermarket in a 'food desert' on healthy food access, availability and prices in the local food environment. We conducted 30 comprehensive in-store audits collecting information on healthy and unhealthy food availability, food prices and store environment, as well as 746 household surveys in two low-income neighborhoods before and after one of the two neighborhoods received a new supermarket. We found positive and negative changes in food availability, and an even greater influence on food prices in neighborhood stores. The supermarket opening in a 'food desert' caused little improvement in net availability of healthy foods, challenging the underpinnings of policies such as the Healthy Food Financing Initiative.
改善低收入社区获得健康食品的机会是国家的优先事项。我们的研究评估了在“食品荒漠”开设超市对当地食品环境中健康食品的可获得性、供应情况和价格的影响。我们在两个低收入社区中的一个社区开设了一家新超市之前和之后，进行了 30 次全面的店内审计，收集有关健康和不健康食品供应情况、食品价格和商店环境的信息，以及在两个低收入社区进行了 746 次家庭调查。我们发现食品供应情况既有积极变化也有消极变化，对社区商店的食品价格的影响更大。在“食品荒漠”中开设超市对健康食品的净供应情况几乎没有改善，这对健康食品融资倡议等政策的基础提出了挑战。
