Healthy Stores 2020 tested a co-designed strategy restricting retailer merchandising of unhealthy foods in a community-level pragmatic, partially randomised, parallel group trial in 20 remote Australian Aboriginal and Torres Strait Islander community stores. We aimed to evaluate the impact of Healthy Stores 2020 on free sugar sales 24-weeks post-trial.
Twenty stores were randomly assigned by a statistician using a single sequence of random assignments to the intervention group, in which a strategy restricted merchandising of unhealthy food (either six or seven strategy components), or to a control group of usual retail practice. The trial was done in partnership with an Indigenous organisation operating in remote Australia. In the post-trial period (24 weeks), immediately following the 25-week RCT, intervention stores (n = 10) continued the strategy but with no external implementation support, and control stores (n = 10) continued usual practice. The primary outcome was impact on purchases (weekly sales data) of free sugars from all foods and beverages (g/MJ) using mixed models. Secondary outcomes included total food and beverage dollars and gross profit (AUD$) and strategy implementation (number of strategies with full implementation assessed via photographic data collected). Trial registration, ACTRN12618001588280.
We observed a difference in sales of total free sugars to energy between the treatment and control groups post-trial (-4.6%, 95% CI -7.1, -1.9). Between group differences in total food and beverage and gross profit dollars were 7.0% (0.9, 13.5) and 11.4% (4.6, 18.6), respectively. Two intervention stores had full implementation of all strategy components and eight intervention stores had compliance with at least four of the seven strategy components at post-trial end.
A health-enabling retail intervention showed an effect on sugar reduction in the post-trial period without adversely impacting profit.

“健康商店2020”在澳大利亚20家偏远的原住民和托雷斯海峡岛民社区商店进行了一项社区层面的务实、部分随机、平行组试验，测试了一项共同设计的策略，该策略限制零售商对不健康食品的销售。我们旨在评估“健康商店2020”在试验后24周对游离糖销售的影响。
由一名统计学家使用单一随机分配序列将20家商店随机分配到干预组，在该组中，一项策略限制了不健康食品的销售（六个或七个策略组成部分），或分配到常规零售做法的对照组。该试验是与一家在澳大利亚偏远地区运营的原住民组织合作进行的。在试验后阶段（24周），即在25周的随机对照试验之后，干预商店（n = 10）继续实施该策略，但没有外部实施支持，而对照商店（n = 10）继续常规做法。主要结果是使用混合模型对所有食品和饮料中游离糖的购买量（每周销售数据，单位：克/兆焦耳）的影响。次要结果包括食品和饮料总金额以及毛利润（澳元）和策略实施情况（通过收集的照片数据评估完全实施的策略数量）。试验注册号，ACTRN12618001588280。
我们观察到试验后治疗组和对照组之间总游离糖与能量的销售额存在差异（-4.6%，95%置信区间 -7.1，-1.9）。食品和饮料总金额以及毛利润的组间差异分别为7.0%（0.9，13.5）和11.4%（4.6，18.6）。在试验结束时，两家干预商店完全实施了所有策略组成部分，八家干预商店至少符合七个策略组成部分中的四个。
一项促进健康的零售干预措施在试验后阶段显示出对减少糖分的效果，且没有对利润产生不利影响。
