目的：本研究的目的是研究位于社会经济不发达和弱势社区的超市中能量密集，营养不良的零食（水果和蔬菜）的可用性。设计：横截面超市审计。设置：墨尔本，澳大利亚。衡量标准包括软饮料、薯片、巧克力、糖果、水果和蔬菜的产品货架空间和品种数量，以及商店规模。（答复率为83%）来自社会经济处境最不利和最不利的五分之一居民区。分配给软饮料的货架空间（23.6 m v. 17.7 m，P = 0.006），薯片（16.5 m v. 13.0 m，P = 0.016）、巧克力（12.2 m v. 10.1 m，P = 0.022）和糖果（6.7 m v. 5.1 m，P = 0.003）在来自社会经济弱势社区的商店中更大。调整商店规模后（贫困地区的商店更大），糖果货架空间（6.3 m v. 5.6 m，P = 0.024）以及所有高能量食品和饮料的综合货架空间（55.0 m v. 48.9 m，P = 0.017）在社会经济弱势社区的商店中仍然更大。分配给水果和蔬菜的货架空间与能量密集型零食的货架空间的比例在调整商店规模后也因社会经济劣势而异（最弱势与最弱势：1.7比2.1，P = 0.025）。水果、蔬菜和巧克力棒的种类在不太贫困的地区更多（P < 0.05）。结论：在社会经济贫困的社区，超市中能量密集的零食和软饮料的暴露更大。这可能会影响与饮食行为有关的购买、消费和文化规范，因此可能不利于消除肥胖水平的已知社会经济梯度。超市进货方式的改革可能是预防肥胖的有效手段。
Objective: The present study aimed to examine the availability of energy-dense, nutrient-poor snack foods (and fruits and vegetables) in supermarkets located in socio-economically advantaged and disadvantaged neighbourhoods.Design: Cross-sectional supermarket audit.Setting: Melbourne, Australia. Measures included product shelf space and number of varieties for soft drinks, crisps, chocolate, confectionery and fruits and vegetables, as well as store size.Subjects: Thirty-five supermarkets (response 83 %) from neighbourhoods in the lowest and highest quintile of socio-economic disadvantage.Results: Shelf space allocated to soft drinks (23.6 m v. 17.7 m, P = 0.006), crisps (16.5 m v. 13.0 m, P = 0.016), chocolate (12.2 m v. 10.1 m, P = 0.022) and confectionery (6.7 m v. 5.1 m, P = 0.003) was greater in stores from socio-economically disadvantaged neighbourhoods. After adjustment for store size (stores in disadvantaged areas being larger), shelf space for confectionery (6.3 m v. 5.6 m, P = 0.024) and combined shelf space for all energy-dense foods and drinks (55.0 m v. 48.9 m, P = 0.017) remained greater in stores from socio-economically disadvantaged neighbourhoods. The ratio of shelf space allocated to fruits and vegetables to that for energy-dense snack foods also varied by socio-economic disadvantage after adjustment for store size (most disadvantaged v. least disadvantaged: 1.7 v. 2.1, P = 0.025). Varieties of fruits and vegetables and chocolate bars were more numerous in less disadvantaged areas (P < 0.05).Conclusions: Exposure to energy-dense snack foods and soft drinks in supermarkets was greater in socio-economically disadvantaged neighbourhoods. This may impact purchasing, consumption and cultural norms related to eating behaviours and may therefore work against elimination of the known socioeconomic gradient in obesity levels. Reform of supermarket stocking practices may represent an effective means of obesity prevention.
