OBJECTIVE
The current study aimed to investigate availability and placement of healthy and discretionary (less healthy) food in supermarkets in Victoria, Australia, and examine variation by supermarket chain and area-level socio-economic disadvantage.
DESIGN
Cross-sectional supermarket audit. Measures included: (i) proportion of shelf space (in square metres) allocated to selected healthy and discretionary food and beverages; (ii) proportion of end-of-aisle, checkout and island bin displays containing discretionary food and beverages and (iii) proportion of space within end-of-aisle, checkout and island bin displays devoted to discretionary food and beverages.
SETTING
Metropolitan areas of Melbourne and Geelong, Australia. Assessment: June-July 2019.
PARTICIPANTS
Random sample of 104 stores, with equal numbers from each supermarket group (Coles, Woolworths, Aldi and Independent stores) within strata of area-level socio-economic position.
RESULTS
Proportion of shelf space devoted to selected discretionary foods was greater for Independent stores (72·7 %) compared with Woolworths (65·7 %), Coles (64·8 %) and Aldi (63·2 %) (all P < 0·001). Proportion of shelf space devoted to selected discretionary food for all Coles, Woolworths and Aldi stores was 9·7 % higher in the most compared with the least disadvantaged areas (P = 0·002). Across all stores, 90 % of staff-assisted checkout displays and 50 % of end-of-aisle displays included discretionary food. Aldi was less likely to feature discretionary food in end-of-aisle and checkout displays compared with other supermarket groups.
CONCLUSIONS
Extensive marketing of discretionary food in all Australian supermarket chains was observed, which is likely to strongly influence purchasing patterns and population diets. Findings should be used to inform private and public sector policies to reduce marketing of discretionary food in supermarkets.
目的
本研究旨在调查澳大利亚维多利亚州超市中健康食品和可自由选择食品（较不健康食品）的供应和摆放情况，并考察超市连锁店和地区社会经济劣势程度的差异。
设计
超市横断面审计。测量指标包括：（i）特定健康食品和可自由选择食品及饮料的货架空间（以平方米计）占比；（ii）端架、结账处和岛式陈列架上陈列的可自由选择食品和饮料的占比；（iii）端架、结账处和岛式陈列架上陈列可自由选择食品和饮料的空间占比。
地点
澳大利亚墨尔本和吉朗的大都市地区。评估时间：2019 年 6 月至 7 月。
参与者
按超市集团（Woolworths、Coles、Aldi 和独立超市）和地区社会经济地位分层，随机抽取 104 家商店的样本，每个分层都有相同数量的商店。
结果
独立超市（72.7%）陈列可自由选择食品的货架空间比例高于 Woolworths（65.7%）、Coles（64.8%）和 Aldi（63.2%）（均 P<0.001）。与最不具社会经济优势的地区相比，所有 Coles、Woolworths 和 Aldi 商店陈列可自由选择食品的货架空间比例高 9.7%（P=0.002）。在所有商店中，90%的人工结账处陈列和 50%的端架陈列都包含可自由选择的食品。与其他超市集团相比，Aldi 在端架和结账处陈列可自由选择食品的可能性更小。
结论
在所有澳大利亚超市连锁店内都观察到了对可自由选择食品的广泛营销，这可能会强烈影响购买模式和人群饮食。调查结果应被用于为私营和公共部门政策提供信息，以减少超市中可自由选择食品的营销。
