Given that older adults are prone to car cessation, they may also be at risk of food insecurity. Online shopping has the potential to become a key solution to this growing social issue. The objective of this study was to understand how mode use relates to food shopping patterns, and what specifically motivates older adults to choose certain travel modes for grocery shopping or to shop online. Sixty-one retired individuals were interviewed in Montreal, Canada. Participants were first asked to discuss their food shopping habits and the modes they used to purchase food. Then, participants were asked open-ended questions about beliefs from the theory of planned behavior. Participants listed advantages/disadvantages, people who approve/disapprove, and facilitating factors/barriers related to travel modes and online grocery shopping. Most participants never used online grocery shopping. Results revealed similarities in shopping styles between car drivers and online shoppers. Both were organized (prepared lists), shopped in bulk, and went on regularly timed shopping trips. Public transit (PT) and active mode users were spontaneous and irregular shoppers who viewed in-person shopping as physical and social activity opportunities. Grocery shopping using these modes could be made easier for some participants if shops offered home delivery after in-store purchases. Car drivers were more likely to adopt online services than PT or active mode users who preferred delivery after in-person shopping to reduce obstacles linked to these modes. In order for online grocery shopping to be integrated as part of one’s established habits, both travel habits and grocery shopping habits must be observed jointly.

鉴于老年人易于戒烟，他们也可能面临粮食不安全的风险。在线购物有潜力成为解决这一日益严重的社会问题的关键解决方案。这项研究的目的是了解模式使用与食品购物模式之间的关系，以及促使老年人选择某些旅行模式进行杂货店购物或在线购物的特殊动机。在加拿大蒙特利尔对61名退休人员进行了采访。首先要求参与者讨论他们的食品购物习惯和购买食品的方式。然后，向参与者询问有关计划行为理论中有关信念的开放性问题。与会者列出了优点/缺点，赞成/反对的人以及与旅行方式和在线杂货店购物有关的促进因素/障碍。大多数参与者从未使用过在线杂货店购物。结果显示，汽车驾驶员和在线购物者的购物风格相似。两者都有条理（准备好的清单），大量购物，并定期进行购物旅行。公共交通（PT）和主动模式用户是自发和不规律的购物者，他们将亲自购物视为身体和社交活动的机会。如果商店在店内购买后提供送货上门服务，则对于某些参与者而言，使用这些模式进行的杂货购物会更容易。与PT或主动模式用户相比，汽车驾驶员更愿意采用在线服务，而PT或主动模式用户更喜欢在亲自购物后送货，以减少与这些模式相关的障碍。为了将在线杂货店购物纳入自己的既定习惯中，
