The effectiveness of initiatives to increase healthy food access may be affected by where people decide to shop. People with poor neighborhood access to large grocery stores develop shopping patterns that require traveling to other areas, and some people who do have neighborhood access also travel elsewhere for food shopping. We sought to gain an understanding of household food shopping patterns in a sample of Black women in terms of where they shopped and why.
All food shopping trips of 35 low- or middle/high-income black mothers or caregivers living with at least one child were identified from grocery shopping receipts collected over four consecutive weeks. Food shopping locations were mapped along with locations of participants' homes and other places they visited during weekly routine travels (e.g. work, child's school). Semi-structured individual interviews elicited narrative information about whether and how grocery shopping trips were linked to routine travels. Inductive content analysis was utilized to identify emergent themes from interviews. Themes were considered in relation to geospatial distances and travel patterns identified through mapping of participants' shopping.
Participants shopped at an average of six different stores, traveling on average a total of 35 miles (sd = 41) (Euclidian distance) over the four weeks. The most frequented store was within a mile of home (57%) or home or another place visited in the weekly routine for about 77% of participants. Interview results emphasized the concept of convenience which referred to geographical proximity to the home or routine destinations and also to potential to save time because several stores were co-located or because the store layout was easy to navigate and familiar. Store selection also related to mode of transportation, pricing, and family preference for certain foods.
People have specific reasons for consistently shopping in areas outside of their neighborhood of residence. Incorporating considerations other than proximity (e.g. time saving while shopping, promoting less familiar foods, pricing) into food environment interventions may facilitate use of new stores by neighborhood residents and thereby increase the viability of these stores as health-promoting food environment interventions.
增加健康食品可及性的举措的有效性可能会受到人们购物地点选择的影响。邻里环境中难以到达大型杂货店的人会形成需要前往其他区域的购物模式,而且一些邻里环境中有大型杂货店的人也会前往其他地方购买食品。我们试图了解黑人女性样本中的家庭食品购物模式,包括她们在哪里购物以及原因。
从连续四周收集的杂货店购物收据中,确定了35位低收入或中高收入黑人母亲或照顾者(与至少一个孩子同住)的所有食品购物行程。食品购物地点与参与者的家庭住址以及他们在每周日常出行中访问的其他地点(如工作地点、孩子的学校)一同绘制在地图上。半结构化的个人访谈收集了有关食品购物行程是否以及如何与日常出行相关联的叙述性信息。采用归纳式内容分析从访谈中识别出浮现的主题。这些主题结合通过绘制参与者购物地点所确定的地理空间距离和出行模式进行考量。
参与者平均在六家不同的商店购物,四周内平均总共出行35英里(标准差 = 41)(欧几里得距离)。最常光顾的商店距离家不到一英里(57%),或者对于约77%的参与者来说,位于家或每周日常访问的其他地方附近。访谈结果强调了便利性的概念,这既指与家或日常目的地的地理接近程度,也指由于几家商店位于同一地点或商店布局易于导航且熟悉而节省时间的可能性。商店选择还与交通方式、价格以及家庭对某些食品的偏好有关。
人们在居住社区以外的地区持续购物有特定原因。将除接近程度之外的其他因素(如购物时节省时间、推广不太常见的食品、价格)纳入食品环境干预措施,可能会促进社区居民使用新商店,从而提高这些商店作为促进健康食品环境干预措施的可行性。
