The existence of dietary inequalities is well-known. Dietary behaviours are impacted by the food environment and are thus likely to follow a spatial pattern. Using 12 months of transaction records for around 50,000 'primary' supermarket loyalty card holders, this study explores fruit and vegetable purchasing at the neighbourhood level across the city of Leeds, England. Determinants of small-area-level fruit and vegetable purchasing were identified using multiple linear regression. Results show that fruit and vegetable purchasing is spatially clustered. Areas purchasing fewer fruit and vegetable portions typically had younger residents, were less affluent, and spent less per month with the retailer.
饮食不平等现象是众所周知的。饮食行为受到食物环境的影响，因此很可能遵循空间模式。本研究使用约 50000 名“主要”超市会员卡持有者 12 个月的交易记录，探索了英格兰利兹市的社区层面的水果和蔬菜购买情况。使用多元线性回归确定了小区域水平水果和蔬菜购买的决定因素。结果表明，水果和蔬菜的购买具有空间集聚性。购买水果和蔬菜份数较少的地区通常居民更年轻、收入较低，并且每月在零售商处的花费也较少。
