Healthy food marketing in the retail environment can be an important driver of fruit and vegetable purchases. In Los Angeles County, the (NEOP) program utilized this strategy to promote healthy eating among low-income families that shop at large retail chain stores. The present study assessed whether self-reported exposure to large retail NEOP interventions, including seeing at least one store visual, watching an in-store cooking demonstration, and/or seeing at least one program advertisement, were associated with increased fruit and vegetable purchases. During fall 2014, the Division of Chronic Disease and Injury Prevention in the Los Angeles County Department of Public Health partnered with Samuels Center to conduct store patron intercept surveys at six large food retail stores participating in NEOP across Los Angeles County. Of 1050 participants who completed the survey, almost a quarter (25.0%) reported seeing at least one visual throughout the store and 9.2% watched a cooking demonstration. Seeing at least one visual and watching a cooking demonstration were not significantly associated with percent dollars spent on fruits and vegetables each week. Among participants who reported being exposed to at least one store visual, those enrolled in the Supplemental Nutrition Assistance Program (SNAP) reported spending 6% more on fruits and vegetables than those who were not enrolled ( = 0.046). Although the NEOP store interventions did not increase store purchases, their educational value may still influence patron food selection, especially if coupled to the monetary resources of SNAP for those who are enrolled.
零售环境中的健康食品营销可以成为推动果蔬购买的重要因素。在洛杉矶县，“邻里环境优化项目”（NEOP）运用这一策略，在大型零售连锁店购物的低收入家庭中推广健康饮食。本研究评估了自我报告的对大型零售NEOP干预措施的接触情况，包括看到至少一个店铺视觉宣传、观看店内烹饪示范和/或看到至少一个项目广告，是否与果蔬购买量的增加有关。2014年秋季，洛杉矶县公共卫生部慢性病与伤害预防司与塞缪尔斯中心合作，在洛杉矶县六家参与NEOP的大型食品零售店进行了店铺顾客拦截调查。在完成调查的1050名参与者中，近四分之一（25.0%）报告称在店内看到至少一个视觉宣传，9.2%观看了烹饪示范。看到至少一个视觉宣传和观看烹饪示范与每周在果蔬上花费的百分比没有显著关联。在报告接触过至少一个店铺视觉宣传的参与者中，参加补充营养援助计划（SNAP）的人报告在果蔬上的花费比未参加者多6%（P = 0.046）。尽管NEOP店铺干预措施没有增加店内购买量，但其教育价值可能仍会影响顾客的食物选择，特别是对于那些参加SNAP的人，如果将其与SNAP的资金资源结合起来的话。
