A 10% excise tax on sugar sweetened beverages (SSBs) was implemented in Barbados in September 2015. A national evaluation has been established to assess the impact of the tax. We present a descriptive analysis of initial price changes following implementation of the SSB tax using price data provided by a major supermarket chain in Barbados over the period 2014-2016. We summarize trends in price changes for SSBs and non-SSBs before and after the tax using year-on-year mean price per liter. We find that prior to the tax, the year-on-year growth of SSB and non-SSB prices was very similar (approximately 1%). During the quarter in which the tax was implemented, the trends diverged, with SSB price growth increasing to 3% and that of non-SSBs decreasing slightly. The growth of SSB prices outpaced non-SSBs prices in each quarter thereafter, reaching 5.9% compared to <1% for non-SSBs. Future analyses will assess the trends in prices of SSBs and non-SSBs over a longer period and will integrate price data from additional sources to assess heterogeneity of post-tax price changes. A continued examination of the impact of the SSB tax in Barbados will expand the evidence base available to policymakers worldwide in considering SSB taxes as a lever for reducing the consumption of added sugar at the population level.
巴巴多斯于 2015 年 9 月对含糖饮料（SSB）征收 10%的消费税。为了评估该税收的影响，已建立了一项国家评估。我们使用巴巴多斯一家主要连锁超市在 2014-2016 年期间提供的价格数据，对该税收实施后最初的价格变化进行了描述性分析。我们根据每升每年的平均价格，总结了税收前后 SSB 和非 SSB 价格变化的趋势。我们发现，在征税之前，SSB 和非 SSB 的价格年增长率非常相似（约为 1%）。在实施税收的季度，趋势出现分歧，SSB 价格增长率上升至 3%，而非 SSB 价格略有下降。此后，SSB 价格的增长速度超过了非 SSB 价格，达到 5.9%，而非 SSB 价格仅为<1%。未来的分析将评估更长时间内 SSB 和非 SSB 价格的趋势，并将整合来自其他来源的价格数据，以评估税收后价格变化的异质性。对巴巴多斯 SSB 税的影响进行持续审查，将扩大全球决策者在考虑 SSB 税作为降低人群中添加糖消费的杠杆时可获得的证据基础。
