From 2011 to 2014, small stores in three communities participated in a community-wide obesity prevention initiative. The study aimed to determine how participation in the initiative influenced store environments and consumer purchases.
Pre- and post-intervention without control. Structured observations of the store environments and intercept surveys of adult shoppers at all stores, and of children at two stores, conducted at baseline and follow-up. Manager/owner interviews regarding perceived impacts of the intervention conducted at follow-up.
SETTING/PARTICIPANTS: Shoppers at nine small stores in three diverse, low-income communities in Northern California.
The store interventions were determined locally with combinations of strategies such as product displays, healthier options, marketing and promotion, store layout, and facility improvements that were implemented to varying degrees at each site.
Changes in store environments and purchases of select foods and beverages.
Stores experienced consistent, but not always significant, declines in purchases of sweets and chips and increases in purchases of fruits and vegetables at select stores. Decreases in purchases of targeted sugar-sweetened beverages were offset by increases in purchases of other sugar-sweetened beverages. Changes in store environments and promotional activities varied widely from store to store and corresponded to variations in changes in purchasing. The owners/managers perceived benefits to their bottom line and community/customer relations, but challenges were identified that may account for the varied degree of implementation.
Substantive improvements in fruit and vegetable availability and promotion were needed to achieve a measurable impact on purchases but reducing purchases of unhealthy foods, like sweets and chips, required a less consistent intensive effort. These findings suggest it may be challenging to achieve the consistent and targeted implementation of changes and ongoing promotional efforts at a large enough proportion of stores where residents shop that would be required to get measurable impacts at the community level.

从 2011 年到 2014 年，三个社区的小商店参与了一项全社区肥胖预防计划。本研究旨在确定参与该计划如何影响商店环境和消费者购买行为。
在没有对照的情况下，进行了干预前后的研究。在基线和随访时，对所有商店的成年购物者和两家商店的儿童进行了商店环境的结构化观察和拦截式调查。在随访时，对经理/店主进行了有关干预影响的感知访谈。
地点/参与者：北加州三个不同低收入社区的九家小商店的购物者。
该商店干预措施是在当地确定的，采用了各种策略的组合，例如产品展示、更健康的选择、营销和促销、商店布局以及设施改进，这些策略在每个地点的实施程度不同。
商店环境和特定食品和饮料购买量的变化。
各商店均经历了持续但并不总是显著的甜食和薯条购买量下降，以及特定商店的水果和蔬菜购买量增加。目标含糖饮料购买量的减少被其他含糖饮料购买量的增加所抵消。各商店的环境变化和促销活动差异很大，与购买变化的变化相对应。店主/经理认为这对他们的底线和社区/客户关系有利，但也发现了一些挑战，这些挑战可能是实施程度不同的原因。
需要实质性地提高水果和蔬菜的供应和促销，才能对购买产生可衡量的影响，但要减少像甜食和薯条这样的不健康食品的购买，需要更持续、更集中的努力。这些发现表明，在居民购物的足够大比例的商店中实现一致和有针对性的变革实施以及持续的促销工作可能具有挑战性，而这是在社区层面产生可衡量影响所必需的。
