Abstract
In 2015, Tesco Express convenience stores implemented a healthy checkouts initiative; products high in fat, salt or sugar were removed from in-queue areas. We compare purchasing of less healthy foods before and after its introduction. Tesco provided store-level sales data (n =1151) for Express stores in England over two 8-week periods, May–July 2014 and 2015. Paired t-tests examined if spending on less healthy foods (biscuits, cakes, crisps and confectionery), as a proportion of total spend, changed between 2015 and 2014. Analyses were repeated for the quantity of less healthy products sold. Compliance was measured through unannounced store visits (n =41). Complete sales data were available for 1101 stores (96%). Mean overall spend increased in 2015 compared with 2014 (£666079.70 [SD 406385.00] vs. £653786.59 [SD 447580.77]; p <0.001). The proportion of total spend from less healthy foods decreased in 2015 versus 2014 (8.03% [SD 2.07] vs. 8.21% [SD 2.17]; p <0.001). Confectionery accounted for the largest proportion of less healthy product spend, showing the biggest reduction (3.91% [SD 1.16] in 2015 vs. 4.12% [SD 1.24] in 2014; p <0.001). Results were similar for quantity of less healthy products sold. Like-for-like sales data from major supermarkets revealed spend on less healthy products rose across the UK over this period. Thirty-nine per cent of stores were fully compliant. In conclusion, following implementation of Tesco's healthier checkouts initiative, there was a small reduction in sales of less healthy foods, largely accounted for by confectionery products. These findings suggest that removal of less healthy products from checkouts might lead to healthier purchasing behaviour. However, store compliance was poor, suggesting scope for improvement.
