Online food delivery services (OFDS) are increasingly used to acquire food prepared out-of-home. Evidence suggests that OFDS commonly promote energy dense and nutrient poor foods, and their regular use may contribute to adverse health outcomes. To inform public health efforts to promote healthy choices on OFDS in Australia, we aimed to explore factors influencing adults' food choices on OFDS and gauge their perceptions towards actions that could support healthier food choices on OFDS.
This is a qualitative study. In-depth, semi-structured interviews were conducted with English speaking adults living in Victoria, Australia, aged 18 to 45 years who reported using OFDS at least once a month. The interview guide was developed to elicit information on factors that prompted participants' food choices on OFDS and gather insights on if and how they could be supported to make healthier food choices on OFDS. Transcripts were deductively coded, guided by the socio-ecological model, using thematic analysis.
Thirty Australian adults participated in the study. Participants were mostly women (80%) with a mean age of 28 years and living in metropolitan Melbourne. 85% had completed higher education, 20% lived with children < 18 years of age and > 80% used OFDS 2-5 times per week. A range of individual factors (motivation to seek comfort food, time and cost considerations), social factor (family influence) and environmental level factors related to navigating OFDS (limited availability and accessibility to healthy food outlets and healthy food options; price promotions, low delivery fee and appealing food images) influenced consumers food choice decisions on OFDS. All participants expressed positive attitudes towards potential actions to help them make healthier food choice decisions on OFDS (such as making healthier foods as default or on promotions).
Individual and social circumstances, together with online marketing techniques, drive consumers' food purchasing decisions on OFDS. Actions are needed to enhance the accessibility, availability and desirability (through increased visibility and price promotions) of healthy food options on OFDS to promote healthy food choices.
在线食品配送服务(OFDS)越来越多地被用于获取外出制作的食品。有证据表明,OFDS通常会推广能量密集型和营养匮乏的食品,经常使用这些服务可能会导致不良健康后果。为了为澳大利亚促进OFDS上健康选择的公共卫生工作提供信息,我们旨在探讨影响成年人在OFDS上食品选择的因素,并衡量他们对有助于在OFDS上做出更健康食品选择的行动的看法。
这是一项定性研究。对居住在澳大利亚维多利亚州、年龄在18至45岁之间、每月至少使用一次OFDS的英语成年居民进行了深入的半结构化访谈。访谈指南旨在获取有关促使参与者在OFDS上做出食品选择的因素的信息,并收集关于是否以及如何支持他们在OFDS上做出更健康食品选择的见解。使用主题分析,在社会生态模型的指导下对访谈记录进行演绎编码。
30名澳大利亚成年人参与了该研究。参与者大多为女性(80%),平均年龄28岁,居住在墨尔本市区。85%的人完成了高等教育,20%的人与18岁以下儿童同住,超过80%的人每周使用OFDS 2至5次。一系列个人因素(寻求安慰食品的动机、时间和成本考虑)、社会因素(家庭影响)以及与使用OFDS相关的环境层面因素(健康食品店和健康食品选择的可用性和可及性有限;价格促销、低配送费和诱人的食品图片)影响了消费者在OFDS上的食品选择决定。所有参与者对有助于他们在OFDS上做出更健康食品选择决定的潜在行动(如将更健康的食品设为默认选项或进行促销)都表达了积极态度。
个人和社会环境,以及在线营销技巧,驱动着消费者在OFDS上的食品购买决定。需要采取行动,提高OFDS上健康食品选择的可及性、可用性和吸引力(通过提高可见性和价格促销),以促进健康食品选择。
