Sugar-sweetened beverage consumption is associated with morbidity and mortality. The retail food environment influences food and beverage purchasing and consumption. This study assesses the impact of a community pharmacy's removal of sweet beverages on overall community sales of carbonated soft drinks (CSD) in a rural setting. We also examined whether the pharmacy intervention affected CSD sales in the town's other food stores.
Weekly CSD sales data were acquired from the three food retailers in the town of Baddeck, Nova Scotia (January 1, 2013 to May 8, 2015, n = 123 weeks). Autoregressive integrated moving average (ARIMA) analysis was used to analyse the interrupted time series data and estimate the impact of the pharmacy intervention (September 11, 2014) on overall CSD sales at the community level. Data were analysed in 2015.
Before the intervention, the pharmacy accounted for approximately 6 % of CSD sales in the community. After the intervention, declines in total weekly average community CSD sales were not statistically significantly. CSD sales at the other food stores did not increase after the pharmacy intervention.
This study was among the first to examine the impact of a restrictive retail food environment intervention, and found a non-significant decline in CSD sales at the community level. It is the first study to examine a retail food environment intervention in a community pharmacy. Pharmacies may have an important role to play in creating healthy retail food environments.
饮用含糖饮料与发病和死亡有关。零售食品环境会影响食品和饮料的购买及消费。本研究评估了在农村地区社区药房移除甜味饮料对碳酸软饮料（CSD）社区总体销售额的影响。我们还研究了药房干预是否影响了该镇其他食品店的CSD销售额。
从新斯科舍省巴德克镇的三家食品零售商处获取了2013年1月1日至2015年5月8日（共123周）的每周CSD销售数据。使用自回归积分滑动平均（ARIMA）分析来分析中断时间序列数据，并估计药房干预（2014年9月11日）对社区层面CSD总体销售额的影响。数据于2015年进行分析。
干预前，该药房的CSD销售额约占社区的6%。干预后，每周社区CSD总平均销售额的下降无统计学意义。药房干预后，其他食品店的CSD销售额并未增加。
本研究是首批考察限制性零售食品环境干预影响的研究之一，发现社区层面CSD销售额有不显著下降。这是第一项考察社区药房零售食品环境干预的研究。药房在营造健康的零售食品环境方面可能发挥重要作用。
