Abstract:
Over 45 jurisdictions globally have implemented sweetened beverage taxes. Researchers and policymakers need to assess whether and how these taxes change beverage demand and supply, their intended and unanticipated health, economic and equity impacts. Lessons from such evaluations can maximise the policies\' success and impact on non-communicable disease prevention globally. We discuss key theoretical, design and methodological considerations to help policymakers, funders and researchers commission and conduct rigorous evaluations of these policies and related disease prevention efforts. We encourage involving the perspectives of various stakeholders on what evaluations are needed given the specific context, what data and methods are appropriate, readily available or can be collected within time and budget constraints. A logic model /conceptual system map of anticipated implications across sectors and scales should help identify optimal study design, analytical techniques and measures. These models should be updated when synthesising findings across diverse methods and integrating findings across subpopulations using similar methods.
摘要:
全球超过45个司法管辖区已经实施了甜味饮料税。研究人员和政策制定者需要评估这些税收是否以及如何改变饮料的需求和供应。他们的预期和意想不到的健康,经济和公平影响。此类评估的经验教训可以最大限度地提高政策的成功率和对全球非传染性疾病预防的影响。我们讨论了关键的理论,设计和方法上的考虑,以帮助决策者,资助者和研究人员委托并对这些政策和相关疾病预防工作进行严格评估。我们鼓励让各利益攸关方就具体背景下需要进行哪些评估的观点参与进来,什么数据和方法是合适的,随时可用或可以在时间和预算限制内收集。跨部门和规模的预期含义的逻辑模型/概念系统图应该有助于确定最佳研究设计,分析技术和措施。当综合不同方法的发现并使用类似方法整合不同亚群的发现时,应更新这些模型。
