The Supplemental Nutrition Assistance Program (SNAP) Online Purchasing Pilot (OPP) authorised the use of SNAP benefits online in Maryland in May 2020. We assessed shopping behaviour and intentions associated with uptake and intended future use of online grocery shopping during and after COVID-19 among SNAP-eligible households.
In this mixed-methods study, participants completed a survey on online grocery shopping, and a purposefully sampled subset participated in focus groups or in-depth interviews between November 2020 and March 2021.
Predominantly urban households in Maryland.
Primary shoppers of SNAP-eligible households with young children ( 310).
Most participants reported first shopping for groceries online after the OPP was implemented (57 %). Families who purchased groceries in-store less frequently were less likely to report ever buying groceries online (rate ratio (RR): 0·66, 95 % CI 0·46, 0·93) compared with weekly grocery shoppers. Shoppers who intended to purchase more groceries online in the next 6 months were more likely to have online shopping experience, although this differed by timing of online grocery service adoption. Participants reported more negative attitudes towards in-store grocery shopping during the pandemic than prior to its onset and cited COVID-19 as a motivator for ordering groceries online in focus groups. Most participants who had shopped online planned to continue after the pandemic (79 %).
Most participants who shopped online started during the COVID-19 pandemic and considered the pandemic a key motivator. Findings suggest that low-income households will continue to shop online, affirming the need for policies that promote equitable access to healthy food online.
补充营养援助计划（SNAP）在线购物试点（OPP）于2020年5月在马里兰州批准了在线使用SNAP福利。我们评估了符合SNAP资格的家庭在2019冠状病毒病期间及之后与接受在线食品杂货购物以及未来在线购物意愿相关的购物行为和意图。
在这项混合方法研究中，参与者完成了一项关于在线食品杂货购物的调查，并且在2020年11月至2021年3月期间，一个经过有目的抽样的子群体参与了焦点小组讨论或深入访谈。
马里兰州主要为城市家庭。
有幼儿的符合SNAP资格家庭的主要购物者（310名）。
大多数参与者报告说在OPP实施后首次进行在线食品杂货购物（57%）。与每周都在店内购买食品杂货的家庭相比，不经常在店内购买食品杂货的家庭报告曾在线购买食品杂货的可能性较小（率比（RR）：0·66，95%置信区间0·46，0·93）。打算在未来6个月内更多地在线购买食品杂货的购物者更有可能有在线购物经验，不过这因采用在线食品杂货服务的时间而异。参与者报告说在疫情期间对店内食品杂货购物的负面态度比疫情开始前更多，并在焦点小组讨论中提到2019冠状病毒病是在线订购食品杂货的一个动机。大多数进行过在线购物的参与者计划在疫情后继续这样做（79%）。
大多数进行在线购物的参与者是在2019冠状病毒病大流行期间开始的，并将大流行视为一个关键动机。研究结果表明低收入家庭将继续在线购物，这证实了需要制定政策以促进公平获取在线健康食品。
