Limitations of traditional geospatial measures, like the modified Retail Food Environment Index (mRFEI), are well documented. In response, we aimed to: (1) extend existing food environment measures by inductively developing subcategories to increase the granularity of healthy . less healthy food retailers; (2) establish replicable coding processes and procedures; and (3) demonstrate how a food retailer codebook and database can be used in healthy public policy advocacy.
We expanded the mRFEI measure such that 'healthy' food retailers included grocery stores, supermarkets, hypermarkets, wholesalers, bulk food stores, produce outlets, butchers, delis, fish and seafood shops, juice/smoothie bars, and fresh and healthy quick-service retailers; and 'less healthy' food retailers included fast-food restaurants, convenience stores, coffee shops, dollar stores, pharmacies, bubble tea restaurants, candy stores, frozen dessert restaurants, bakeries, and food trucks. Based on 2021 government food premise licences, we used geographic information systems software to evaluate spatial accessibility of healthy and less healthy food retailers across census tracts and in proximity to schools, calculating differences between the traditional . expanded mRFEI.

N/A.
Of the 10 828 food retailers geocoded, 26 % were included using traditional mRFEI measures, while 53 % were included using our expanded categorisation. Changes in mean mRFEI across census tracts were minimal, but the healthfulness of food environments surrounding schools significantly decreased.
Overall, we show how our mRFEI adaptation, and transparent reporting on its use, can promote more nuanced and comprehensive food environment assessments to better support local research, policy and practice innovations.
传统地理空间指标（如改良零售食品环境指数（mRFEI））的局限性已得到充分证明。有鉴于此，我们旨在：（1）通过归纳性地开发子类别来扩展现有的食品环境指标，以增加健康食品零售商和不太健康食品零售商的粒度；（2）建立可复制的编码流程和程序；（3）展示食品零售商代码本和数据库如何用于健康公共政策宣传。
我们扩展了 mRFEI 指标，以便“健康”食品零售商包括杂货店、超市、大型超市、批发商、散装食品店、农产品店、肉店、熟食店、鱼和海鲜店、果汁/冰沙吧、新鲜和健康的快餐零售商；“不太健康”食品零售商包括快餐店、便利店、咖啡店、一元店、药店、珍珠奶茶店、糖果店、冷冻甜品店、面包店和食品卡车。基于 2021 年政府食品前提许可证，我们使用地理信息系统软件评估了健康和不太健康食品零售商在普查区的空间可达性以及在学校附近的可达性，计算了传统 mRFEI 和扩展 mRFEI 之间的差异。

无。
在所地理编码的 10828 家食品零售商中，26%使用传统 mRFEI 措施包括在内，而 53%使用我们扩展的分类包括在内。普查区之间 mRFEI 的平均值变化很小，但学校周围食品环境的健康度显著下降。
总体而言，我们展示了如何通过调整 mRFEI 并透明报告其使用情况，以促进更细致和全面的食品环境评估，从而更好地支持当地的研究、政策和实践创新。
