BACKGROUND Taxation of sugar-sweetened beverages (SSBs), as a component of a comprehensive strategy, has emerged as an apparent effective intervention to counteract the rising prevalence of overweight and obesity. Insight into the political and public acceptability may help adoption and implementation in countries with governments that are considering an SSBs tax. Hence, we aimed to conduct a systematic review and meta-analysis to synthesize the existing qualitative and quantitative literature on political and public acceptability of an SSBs tax. METHODS Four electronic databases (PubMed, Embase, Scopus, Web of Science) were searched until November 2018. The methodological quality of the included studies was assessed using the Mixed Methods Appraisal Tool. Qualitative studies were analyzed using a thematic synthesis. Quantitative studies were analyzed using a random-effects meta-analysis for the pooling of proportions. RESULTS Thirty-seven articles reporting on forty studies were eligible for inclusion. Five themes derived from the thematic synthesis: (i) beliefs about effectiveness and cost-effectiveness, (ii) appropriateness, (iii) economic and socioeconomic benefit, (iv) policy adoption and implementation, and (v) public mistrust of the industry, government and public health experts. Results of the meta-analysis indicated that of the public 42% (95% CI = 0.38-0.47) supports an SSBs tax, 39% (0.29-0.50) supports an SSBs tax as a strategy to reduce obesity, and 66% (0.60-0.72) supports an SSBs tax if revenue is used for health initiatives. CONCLUSIONS Beliefs about effectiveness and cost-effectiveness, appropriateness, economic and socioeconomic benefit, policy adoption and implementation, and public mistrust of the industry, government and public health experts have important implications for the political and public acceptability of an SSBs tax. We provide recommendations to increase acceptability and enhance successful adoption and implementation of an SSBs tax: (i) address inconsistencies between identified beliefs and scientific literature, (ii) use raised revenue for health initiatives, (iii) communicate transparently about the true purpose of the tax, and (iv) generate political priority for solutions to the challenges to implementation.

含糖饮料税的政治和公众接受度：混合方法的系统审查和荟萃分析。

背景技术作为综合策略的组成部分，对含糖饮料（SSB）征税已成为一种明显的有效干预措施，可以抵消超重和肥胖症的流行。深入了解政治和公众的接受程度可能会有助于那些正在考虑实施SSB税的政府所在的国家/地区采用和实施。因此，我们的目标是进行系统的审查和荟萃分析，以汇总有关SSB税的政治和公众接受度的现有定性和定量文献。方法检索直到2018年11月的四个电子数据库（PubMed，Embase，Scopus，Web of Science）。使用混合方法评估工具评估纳入研究的方法学质量。使用专题综合分析对定性研究进行了分析。使用随机效应荟萃分析对定量研究进行了汇总。结果有37篇报道40项研究的文章符合纳入条件。专题综合得出了五个主题：（i）关于有效性和成本效益的信念，（ii）适当性，（iii）经济和社会经济效益，（iv）政策的采用和实施，以及（v）公众对该行业的不信任，政府和公共卫生专家。荟萃分析的结果表明，公众中42％（95％CI = 0.38-0.47）支持SSBs税，39％（0.29-0.50）支持SSBs税作为减少肥胖的策略，66％（0.60） -0.72）支持将SSB税用于健康计划。结论有关有效性和成本效益，适当性，经济和社会经济效益的信念，政策的采用和实施以及行业，政府和公共卫生专家的公众不信任，对于SSB税的政治和公众接受度具有重要意义。我们提供建议以提高可接受性并加强SSB税的成功采用和实施：（i）解决已确定的信念与科学文献之间的矛盾，（ii）将筹集的收入用于健康计划，（iii）透明地就SSB的真正目的进行沟通税收；（iv）在解决实施挑战方面产生政治上的优先权。
