Abstract

Stark, widening health and income inequalities in the United Kingdom underpin the need for increased support for low-income families to access affordable and nutritious foods. Using anonymised supermarket loyalty card transaction records, this study aimed to assess how an additional Healthy Start voucher (HSV) top-up of £2, redeemable only against fruit and vegetables (FVs), was associated with FV purchases among at-risk households. Transaction and redemption records from 150 loyalty card-holding households, living in northern England, who had engaged with the top-up scheme, were analysed to assess the potential overall population impact. Using a pre-post study design, 133 of these households' records from 2021 were compared with equivalent time periods in 2019 and 2020. Records were linked to product, customer and store data, permitting comparisons using Wilcoxon matched-pairs sign-ranked tests and relationships assessed with Spearman's Rho. These analyses demonstrated that 0.9 more portions of FV per day per household were purchased during the scheme compared to the 2019 baseline (p = 0.0017). The percentage of FV weight within total baskets also increased by 1.6 percentage points (p = 0.0242), although the proportional spend on FV did not change. During the scheme period, FV purchased was higher by 0.4 percentage points (p = 0.0012) and 1.6 percentage points (p = 0.0062) according to spend and weight, respectively, in top-up redeeming baskets compared to non-top-up redeeming baskets with at least one FV item and was associated with 5.5 more HSV 'Suggested' FV portions (p < 0.0001). The median weight of FV purchased increased from 41.83 kg in 2019 to 54.14 kg in 2021 (p = 0.0017). However, top-up vouchers were only redeemed on 9.1% of occasions where FV were purchased. In summary, this study provides novel data showing that safeguarding funds exclusively for FV can help to increase access to FV in low-income households. These results yield important insights to inform public policy aimed at levelling up health inequalities.

超市补充健康起步券增加了低收入家庭的水果和蔬菜购买量。
严峻的是,英国日益扩大的健康和收入不平等,使低收入家庭有必要获得负担得起的营养食品。本研究使用匿名超市忠诚卡交易记录,旨在评估额外的2英镑健康起步代金券(HSV)充值(只能兑换水果和蔬菜)与风险家庭购买FV的关系。分析了150个居住在英格兰北部的忠诚卡持有者家庭的交易和赎回记录,这些家庭参与了充值计划,以评估潜在的整体人口影响。使用研究前后的设计,将这些家庭2021年的133份记录与2019年和2020年的同期进行了比较。记录与产品、客户和商店数据相关联,允许使用Wilcoxon配对符号排序测试进行比较,并使用Spearman的Rho评估关系。这些分析表明,与2019年的基线相比,该计划期间每个家庭每天购买的FV增加了0.9份(p = 0.0017)。FV重量在总篮子中的百分比也增加了1.6个百分点(p = 0.0242),尽管FV的比例支出没有改变。在该计划期间,购买的FV增加了0.4个百分点(p = 0.0012)和1.6个百分点(p = 0.0062),与至少有一个FV项目的非充值兑换篮相比,充值兑换篮中的HSV“建议”FV分量增加5.5份(p
