项目摘要

DESCRIPTION (provided by applicant): Innovative and culturally appropriate multilevel health communications interventions are desperately needed to address the chronic disease epidemic in high-risk populations, such as low-income urban African Americans (AA). However, the vast majority of communications strategies have focused on educating individual consumers about healthy food choices, while in poor urban settings the lower availability of affordable healthy food choices greatly limits the impact of these messages. We will work with 3 wholesalers and 24 small retail food stores to develop and test novel strategies in Baltimore, Maryland, including: 1) multilevel health communications alone directed at wholesalers, retailers and low-income AA consumers intended to enhance willingness to stock and/or purchase healthy foods; 2) pricing strategies (performance based allowances) directed at wholesalers and retailers to increase their stocking of healthy foods at reduced prices; and 3) combined health communications and pricing strategies. Intervention strategies will be tailored to meet the needs of the target populations based on formative research and stakeholder input. Our proposed work is based on significant field experience in this setting, including the development of evaluation tools to assess change in stocking and pricing of key foods (at the store level), and psychosocial factors, dietary intake, and food purchasing behaviors (at the consumer level). Our study has the following aims: 1) Conduct formative research with representatives of multiple levels of the Baltimore food environment (i.e., local wholesalers and retail food store owners) in order to select key foods for promotion, determine appropriate communication strategies (e.g., messages, channels, materials) for each level, and select the most appropriate pricing approach (i.e., performance based allowance structure and stipulations). 2) Pilot the multi-level program with three wholesalers and 24 food stores (6 control, 6 health communications only, 6 pricing only, 6 combined), and assess program implementation through detailed process evaluation. 3) Assess impact of the pilot program on a) the stocking, pricing, marketing, and sales volume of promoted foods at wholesale and retail levels, and b) food purchasing behaviors and associated psychosocial variables (i.e., self-efficacy, intentions, perceived cost) at the consumer level (final sample n=12 consumers/store, 288 total). The proposed research directly addresses the objectives of the PA by seeking to develop effective, multilevel communication strategies to improve diet and reduce risk for diet-related chronic diseases. We anticipate this design will demonstrate the value of a multipronged and multilevel health communications approach to obesity and chronic disease prevention, and will lead to a large-scale trial and informed policies designed to improve food availability and affordability in low-income urban settings.

描述（由申请人提供）：迫切需要进行创新和文化适当的多层次健康传播干预措施，以解决高风险人群中的慢性病流行，例如低收入城市的非裔美国人（AA）。但是，绝大多数沟通策略都集中在教育个人食品选择方面，而在贫困的城市环境中，负担得起的健康食品选择较低的可用性极大地限制了这些信息的影响。我们将与3个批发商和24家小型零售食品商店合作，在马里兰州巴尔的摩制定和测试新型策略，包括：1）仅针对批发商，零售商和低收入AA消费者，旨在增强股票和/或购买健康食品的愿望； 2）针对批发商和零售商的定价策略（基于绩效的津贴）以降低的价格增加健康食品的库存； 3）结合健康沟通和定价策略。将根据形成性研究和利益相关者的意见来量身定制干预策略，以满足目标人群的需求。我们提出的工作基于在这种情况下的重要现场经验，包括开发评估工具，以评估关键食品（商店一级）以及心理社会因素，饮食摄入和食品购买行为（在消费者水平上）的变化。我们的研究具有以下目的：1）与多个级别的巴尔的摩食品环境（即本地批发商和零售商店所有者）的代表进行形成性研究，以便选择促进的关键食物，确定适当的交流策略（例如，信息，通道，渠道，材料）为每个级别，并选择最合适的定价方法（即基于允许的允许允许的结构和允许的结构）。 2）通过三个批发商和24家食品商店（6个对照，仅6个健康通信，仅6个定价，6组合并），并通过详细的流程评估来评估计划实施。 3）评估试点计划对a）批发和零售水平上促销食品的库存，定价，营销和销量的影响，b）食品购买行为以及相关的心理社会变量（即自我效能，意图，意图，感知的成本）在消费者级别上（最终样本n = 12个消费者n = 12个消费者/商店/商店/商店/商店，总计2888888888888888.总计）。拟议的研究直接通过寻求制定有效的多层次交流策略来改善饮食并降低与饮食相关的慢性疾病的风险来直接解决PA的目标。我们预计，这种设计将证明对肥胖和慢性病预防的多重和多层次健康通信方法的价值，并将导致大规模试验，并旨在提高低收入城市环境中的食品可用性和可负担性的知情政策。
