项目摘要

DESCRIPTION (provided by applicant): As the prevalence of obesity has increased, public health experts have increasingly focused on the environments that shape overeating and unhealthy food choices. Retail grocery stores are pivotally positioned to influence choices and favorably affect energy balance. Greater availability of healthier foods, if translated to health-promoting purchases, can positively affect diet quality among those at greatest risk for obesity- low-income, ethnic minorities. The aims of the proposed study are: 1. To evaluate, in a cluster randomized controlled trial design, effects of in-store healthy food marketing strategies on sales and purchase of healthier items in six product categories (milk, frozen entrees, beverage checkout coolers, bread, salty snacks and cheese); and 2. To evaluate the association of changes in supermarket food marketing environments with changes in sales of specific healthier food items in the same six product categories; and 3. To examine the relationships between neighborhood characteristics and changes in sales and purchases of healthier items in the six product categories. We hypothesize that sales of targeted products will be significantly higher, and that more health- focused food marketing environments will be associated with higher sales of healthy food items. The study will be conducted in 32 supermarkets in urban, low-income, high-minority neighbor- hoods in the mid-Atlantic and Northeast regions. Intervention strategies will include prime placement, increased visibility of healthier products, call-out signs, and taste-testing for milk. Control stores will be assessment-only. Supermarket chains will help implement the strategies and provide data on sales of targeted products. Interventions will be conducted for 2 years, with an emphasis on scalability and long-term sustainability. The primary outcome measures of purchasing will be weekly sales per store for each product. Individual purchasing will be assessed in a cohort of shoppers by interviews and shopping receipts. The Grocery Marketing Environment Assessment (GMEA) tool will be used to assess marketing environments. The research team completed a randomized pilot study of a 6-month intervention in eight supermarkets, which demonstrated the impact of the interventions on three food categories. The proposed study will provide an expanded and extended, larger-scale, rigorous test of novel and widely applicable strategies to encourage healthy retail sales, complement increased- access initiatives, and reduce health disparities in obesity and related diseases.

描述（由申请人提供）：随着肥胖症的流行率增加，公共卫生专家越来越关注形成暴饮暴食和不健康食物选择的环境。零售杂货店的关键位置是影响选择和有利地影响能量平衡。更健康食品的供应增加，如果转化为促进健康的购买，可以积极影响肥胖风险最大的人群-低收入少数民族-的饮食质量。本研究的目的是：1.采用随机对照试验设计，评价店内健康食品营销策略对销售额的影响以及购买六类较健康的食品（牛奶、冷冻主菜、饮料冷藏柜、面包、咸味小吃和奶酪）;以及评估超市食品营销环境的变化与相同六个产品类别中特定健康食品销售变化的关系;以及3.研究社区特征与六个产品类别中健康产品的销售和购买变化之间的关系。我们假设，目标产品的销售将显着更高，更注重健康的食品营销环境将与更高的健康食品销售相关联。这项研究将在大西洋中部和东北部地区的城市、低收入、少数民族聚居区的32家超市进行。干预策略将包括黄金位置，增加更健康产品的可见度，呼叫标志和牛奶口味测试。对照品储存仅用于评估。连锁超市将帮助实施这些战略，并提供目标产品的销售数据。干预措施将持续2年，重点是可扩展性和长期可持续性。购买的主要结果测量将是每个商店每种产品的每周销售额。个人购买将通过访谈和购物收据在一组购物者中进行评估。杂货销售环境评估（GMEA）工具将用于评估销售环境。研究小组在8家超市完成了一项为期6个月的随机试点研究，展示了干预措施对三种食品类别的影响。这项拟议的研究将提供一个扩大和延伸，更大规模，严格的测试新的和广泛适用的战略，以鼓励健康的零售，补充增加获得倡议，并减少肥胖和相关疾病的健康差距。
