我们的目的是评估当地含糖饮料（SSB）健康促进和休闲中心场地价格上涨20便士的影响，并估计对消费的影响。分析了2015年1月至2017年7月期间谢菲尔德市休闲中心的月度冷饮销售数据和出勤率。采用中断时间序列方法估计自2016年8月引入SSB政策后SSB和非SSB冷饮的每次出勤消费量变化，并对季节变化和自相关进行调整。SSB价格弹性估计固定效应双对数模型的SSB产品类型（汽水罐，汽水瓶，汽水后混合，能量饮料，浓缩果汁）。我们估计，自该政策实施以来，每年出售的SSB单位减少了31%（95% CI 4%，59%）。我们没有观察到对果汁或水的替代影响，但发现引入税收后其他人工甜味非SSB产品的销量增加了27%（95%CI 6%，47%）。价格弹性分析表明，价格上涨1%，同时促进健康，导致SSB的需求下降3.8%（95%CI 3.1%-4.4%）。儿童友好型和高咖啡因能量饮料的需求价格弹性最高。与其他SSB税收政策评估相比，休闲中心场所对SSB饮料的需求对该政策反应强烈，特别是对儿童友好型和高咖啡因能量饮料的需求。该政策还增加了对碳酸非SSB的购买。
We aimed to evaluate the impact of a local sugar sweetened beverages (SSB) health promotion and 20p price increase in leisure centre venues and estimate the impact on consumption. Monthly cold drinks sales data and attendance at leisure centres across the city of Sheffield were analysed over the period January 2015-July 2017. Interrupted time-series methods were employed to estimate changes in consumption per attendance of SSB and non-SSB cold drinks following the introduction of the SSB policy from August 2016 adjusting for seasonal variation and autocorrelation. SSB price elasticities were estimated with fixed effects log-log models by SSB product type (soda can, soda bottle, soda post mix, energy drinks, juice from concentrate). We estimated a 31% (95% CI 4%, 59%) reduction in units of SSB sold per attendance in the year since the policy was introduced. We did not observe substitution effects to fruit juice or water but found sales of other artificially sweetened non-SSB products increased by 27% (95% CI 6%, 47%) after the introduction of the tax. Price elasticity analysis identified that a 1% increase in price alongside health promotion leads to a 3.8% (95% CI 3.1% 4.4%) decrease in demand for SSB’s. Price elasticity of demand was highest for child friendly and high caffeine energy drinks. Demand for SSB drinks at leisure centre venues is highly responsive to the policy, particularly for child-friendly and high caffeine energy drinks, compared with other SSB tax policy evaluations. The policy also increased purchases of carbonated non-SSB.
