"Factors Influencing Food Selection"

 说明(申请人提供)：2尽管对外出食品的依赖日益增加，但杂货店购物仍然是家庭获取食物的主要方法3，因此是其饮食摄入量和饮食质量的一个重要决定因素。4杂货购物每周发生多次，在某些种族群体(例如，5名拉丁裔)中更频繁，这使其成为未来干预研究的一个重要的可改变的决定因素。这项名为《店内和亲子对食品购物的影响》的研究探讨了影响食品店决策和购买行为的三个重要来源：店内因素(例如，产品8如何摆放在货架上)、亲子互动特征(例如，亲子沟通和育儿行为)，以及亲子互动期间的产品因素(即产品健康)10围绕食品和饮料产品请求(N=两家商店的150个二元组)。这项为期两年的混合11种方法研究将使用眼球跟踪技术来识别暗示父母12岁和孩子购买请求的商店环境的各个方面。这对双胞胎将在13号杂货店的一次购物过程中每人戴上眼睛跟踪眼镜，从父母和14个孩子的角度捕捉整个购物过程的视觉和音频数据。家长访谈将捕捉家庭食品购买行为、育儿行为、15以及相关的文化和经济因素。我们的方法是创新的，重点是确定16种干预方法，包括影响父母和孩子购买请求的店内和亲子因素，17种父母养育行为，以及父母的杂货购物决策和购买行为。这项研究意义重大，因为重点是了解影响消费者购买行为的三个来源(即，在19岁的商店里，亲子和产品因素)，同时关注受超重影响不成比例的人群(即拉丁裔) 与普通人群相比，肥胖者更频繁地去商店，更有可能带着孩子去商店，而且经常去超市以外的商店购买食品(在有限种类的食品店进行拟议的研究)。这项拟议的研究将扩展我们的店内环境研究和23个亲子观察研究，以更好地了解店内、亲子和产品因素与父母和孩子的购买需求和育儿行为相关的24个因素，以及这些因素与父母25杂货购物决策和购买行为的关系。这项研究计划的长期目标是制定干预策略，以识别和解决影响健康行为的多种来源27，包括人际和环境影响。这在概念上与我们在家庭和餐馆进行的更大规模的育儿研究是一致的。通过采用混合方法对29个不同的和可修改的影响来源进行研究，这项研究将为未来的第30组随机对照试验奠定基础，以检查对儿童和父母饮食摄入的干预效果。

 DESCRIPTION (provided by applicant): 2 despite increasing reliance on away-from-home foods, grocery shopping continues to be the primary method 3 by which families obtain food and thus is an important determinant of their dietary intake and diet quality. 4 Grocery shopping occurs multiple times per week and even more frequently among certain ethnic groups (e.g., 5 Latinos), making it an important modifiable determinant to study for future intervention research. The proposed 6 study, "In-store and parent-child influences on food shopping" addresses three important sources of 7 influence on decision-making and purchasing behavior in food stores: in-store factors (e.g., how the products 8 are displayed on the shelves), parent-child interactional characteristics (e.g., parent-child communication and 9 parenting behaviors), and product factors (i.e., product healthfulness) during parent-child interactions 10 surrounding food and beverage product requests (N=150 dyads across two stores). This two-year, mixed- 11 methods study will use eye-tracking technology to identify aspects of the in-store environment that cue parents' 12 and children's purchase requests. The dyad will each wear eye-tracking glasses during a single grocery 13 shopping trip that capture visual and audio data for the entire shopping trip from both the parent's and the 14 child's perspectives. Parent interviews will capture household food shopping behavior, parenting behaviors, 15 and relevant cultural and economic factors. Our approach is innovative in its focus on identifying methods for 16 intervening on in-store and parent-child factors that influence parents' and children's purchase requests, 17 parenting behaviors, and parents' grocery shopping decision-making and purchasing behavior. The study is 18 significant given the focus on understanding three sources of influence on what consumers purchase (i.e., in- 19 store, parent-child and product factors), while focusing on a population (i.e., Latinos) that is disproportionately 20 affected by overweight and obesity, shops more frequently than the general population, is more likely to shop 21 with children, and frequently shops for food outside of supermarkets (in limited assortment food stores where 22 the proposed study will be conducted). The proposed study will extend our in-store environment research and 23 parent-child observational research to better understand in-store, parent-child, and product factors associated 24 with parents' and children's purchase requests and parenting behaviors, and how these relate to parent 25 grocery shopping decision-making and purchasing behavior. The long-term goal of this program of research is 26 to develop intervention strategies that recognize and address the multiple sources of influence on health 27 behaviors, including interpersonal and environmental influences. It is conceptually consistent with our larger 28 body of parenting research in family homes and in restaurants. By taking a mixed-methods approach to 29 studying distinct and modifiable sources of influence, this study will form the foundation for a future group 30 randomized controlled trial to examine intervention effects on dietary intake in children and parents.
