Nutrition education may be most effective when personally tailored. Individualised electronic supermarket sales data offer opportunities to tailor nutrition education using shopper's usual food purchases. The present study aimed to use individualised electronic supermarket sales data to tailor nutrition resources for an ethnically diverse population in a large supermarket intervention trial in New Zealand.
Culturally appropriate nutrition education resources (i.e. messages and shopping lists) were developed with the target population (through two sets of focus groups) and ethnic researchers. A nutrient database of supermarket products was developed using retrospective sales data and linked to participant sales to allow tailoring by usual food purchases. Modified Heart Foundation Tick criteria were used to identify 'healthier' products in the database suitable for promotion in the resources. Rules were developed to create a monthly report listing the tailored and culturally targeted messages to be sent to each participant, and to produce automated, tailored shopping lists.
Culturally targeted nutrition messages (n = 864) and shopping lists (n = 3 formats) were developed. The food and nutrient database (n = 3000 top-selling products) was created using 12 months of retrospective sales data, and comprised 60%'healthier' products. Three months of baseline sales data were used to determine usual food purchases. Tailored resources were successfully mailed to 123 Māori, 52 Pacific and 346 non-Māori non-Pacific participants over the 6-month trial intervention period.
Electronic supermarket sales data can be used to tailor nutrition education resources for a large number of ethnically diverse supermarket shoppers.
营养教育在个性化时可能最有效。个性化电子超市销售数据为根据购物者的日常食品购买来定制营养教育提供了机会。本研究旨在使用个性化电子超市销售数据为新西兰一家大型超市干预试验中的多种族人群定制营养资源。
使用目标人群（通过两组焦点小组）和族裔研究人员开发了文化上合适的营养教育资源（即信息和购物清单）。使用回溯销售数据开发了超市产品的营养数据库，并与参与者的销售数据相关联，以便根据日常食品购买进行定制。使用修改后的心脏基金会Tick 标准来识别数据库中适合在资源中推广的“更健康”产品。制定了规则，创建每月报告，列出要发送给每个参与者的定制和文化上有针对性的信息，并生成自动化的定制购物清单。
开发了具有针对性的文化营养信息（n=864）和购物清单（n=3 种格式）。使用 12 个月的回溯销售数据创建了食品和营养数据库（n=3000 种最畅销产品），其中包含 60%的“更健康”产品。使用三个月的基线销售数据来确定日常食品购买情况。在 6 个月的试验干预期间，成功向 123 名毛利人、52 名太平洋岛民和 346 名非毛利非太平洋岛民参与者邮寄了定制资源。
电子超市销售数据可用于为大量多种族超市购物者定制营养教育资源。
