    背景:以前的研究已经确定了烟草业采用的定价策略,以尽量减少烟草税的影响,但这些研究大多是针对高收入国家的。这项研究考察了行业价格对墨西哥最近增加卷烟税的反应,包括在拉丁美洲迅速扩张的胶囊卷烟领域。
    方法:根据准实验设计,使用NielsenIQ许可的2018年10月至2021年9月期间墨西哥卷烟价格和销售数据,以固定效应模型按产品分析消费税增加后的价格变化。为了探索异质反应,估计按卷烟属性分类,如胶囊的存在和细分市场。还评估了差速换档。
    结果:在2020年1月将烟草税从2011MX美元0.35(约0.02美元)提高到2020MX美元0.4944(约0.0283美元),与卷烟价格实际上涨8%有关。然而,一些香烟类型,包括溢价到折扣段,显示价格上涨大于税收增加,这降低了超低价格香烟的相对价格。而不是一次徒步旅行,在2020年的头几个月,所有类型的卷烟的价格都在逐步提高。胶囊香烟采用了两种定价策略的组合。2021年较小的年度通胀税收调整已完全转给消费者,保持实际价格不变。
    结论:该行业提高价格的能力超过了税收的增加,并且顺利地管理了这些价格上涨,这表明墨西哥还有更大的烟草税增加空间。烟草税的未来发展可以考虑完全具体的税收结构或最低税收,以减轻市场分割和差异转移的不利影响。
    BACKGROUND: Previous studies have identified pricing strategies that the tobacco industry employs to try to minimise the impact of tobacco taxation, but these studies are mostly about high-income countries. This research examines industry price responses to a recent cigarette tax increase in Mexico, including in the capsule cigarette segment that has expanded rapidly in Latin America.
    METHODS: Data of cigarette prices and sales in Mexico between October 2018 and September 2021 licensed from NielsenIQ were used following a quasi-experimental design to analyse price changes after excise tax increases with fixed effect models by product. To explore heterogeneous responses, estimates were disaggregated by cigarette attributes such as presence of capsules and market segment. Differential shifting was also assessed.
    RESULTS: Increasing the tobacco tax from 2011MX$0.35(≈US$0.02) to 2020 MX$0.4944(≈US$0.0283) in January 2020 was associated with an overall 8% cigarette price increase in real terms. However, some cigarette types, including premium to discount segments, exhibited price increases larger than the tax increase, which reduced the relative price of ultra-low-priced cigarettes. Instead of a single hike, prices were gradually raised throughout the first months of 2020 for all cigarette types. A combination of both pricing strategies was employed for capsule cigarettes. The 2021 smaller tax adjustment for annual inflation was fully passed onto consumer, maintaining real prices constant.
    CONCLUSIONS: The industry\'s ability to raise prices more than the tax increase and manage these price increases smoothly suggests that there was room for larger tobacco tax increases in Mexico. Future developments on tobacco taxes could consider a fully specific tax structure or minimum taxes to mitigate the adverse effects of market segmentation and differential shifting.

    背景:2021年,四分之一的法国成年人每天吸烟,而经济合作与发展组织(OECD)国家则为六分之一。加强烟草控制政策,2016年,法国开始实施一揽子政策,其中包括为期3年的逐步提价,普通包装,一年一度的社会营销活动,促进戒烟和尼古丁替代产品的报销。这项研究旨在评估这一政策方案对健康和经济的影响。
    方法:对疾病病例的长期政策影响,通过使用OECD非传染性疾病战略公共卫生规划微观模拟模型,评估了医疗支出以及劳动力参与和生产率的收益.该模型提供了一揽子政策所产生的关于吸烟流行率的历史和预测趋势。
    结果:在2023-2050年期间,该政策计划估计可避免约403万(2.09-11.84万)例慢性病,每年节省5.78亿欧元(3.65-1.848亿欧元)的卫生支出,并将就业和劳动力生产率提高,相当于每年增加19800名(9100-59900)全职工人,与未实施干预包的情况相比。干预费用估计每年约为1.48亿欧元。对于一揽子政策中投资的每一个欧元,4欧元将在医疗保健支出的长期节省中返还。
    结论:法国实施的烟草控制政策计划,以吸烟为目标并促进戒烟是一种有效的干预措施,具有出色的投资回报。
    BACKGROUND: One in four French adults smoked daily in 2021, compared with one in six in Organisation for Economic Co-operation and Development (OECD) countries. To strengthen its tobacco control policy, in 2016, France has started implementing a policy package that includes a 3-year gradual price increase, plain packaging, an annual social marketing campaign promoting cessation and the reimbursement of nicotine replacement products. This study aims to evaluate the health and economic impact of this policy package.
    METHODS: The long-term policy impact on disease cases, healthcare expenditure and gains in labour participation and productivity was evaluated by using the OECD microsimulation model for Strategic Public Health Planning for Non-Communicable Diseases. The model was fed with historical and projected trends on tobacco smoking prevalence as produced by the policy package.
    RESULTS: Over the period 2023-2050, the policy package is estimated to avoid about 4.03 million (2.09-11.84 million) cases of chronic diseases, save €578 million (365-1848 million) per year in health expenditure and increase employment and workforce productivity by the equivalent to 19 800 (9100-59 900) additional full-time workers per year, compared with a scenario in which the intervention package is not implemented. The intervention cost is estimated at about €148 million per year. For each euro invested in the policy package, €4 will be returned in long-term savings in healthcare expenditure.
    CONCLUSIONS: The tobacco control policy package implemented by France, targeting smoking initiation and promoting tobacco cessation is an effective intervention with an excellent return on investment.

    背景:人们对权力的关注与日俱增,影响力,以及大型全球咨询公司的运营对健康和公平的威胁。总的来说,这些公司支持新自由主义的政策环境,在公共卫生之前促进商业利益。全球咨询公司是健康的商业决定因素,近年来不断发展的研究领域。然而,这项研究主要集中在特定的公司或行业部门,尤其是那些生产有害产品的产品,包括超加工食品,酒精,和化石燃料。因此,重要的是将重点扩大到包括大型全球咨询公司,并将公共卫生和公平视角置于其运营之上。
    方法:全球咨询公司存在广泛的利益冲突。这些源于他们自己的员工与政府和监管机构之间的“旋转门”就业策略。这些公司还就税收和其他事项向政府提供建议,同时向企业客户提供减少税收的方法。他们为化石燃料公司提供建议,同时也为政府提供气候和健康政策方面的建议。这些公司通过将传统的公共部门角色外包给这些私人利益来破坏公共部门的能力。咨询公司通过与高等教育部门的接触来促进私人利益,从而削弱了负责任的大学理事会对大学事务进行透明管理的传统。虽然不能将全球化和先进资本主义相关问题对健康和公平造成的所有负面影响归咎于私人咨询公司,它们在放大它们方面发挥了作用。
    结论:解决全球咨询公司的负面影响将需要加强公共部门,加强透明度,问责制,尽量减少利益冲突。它还需要批判性思维,反话语,和行动主义重新构建支持新自由主义治理思想的叙述,这些思想在政府和商业领域都得到了推广。
    BACKGROUND: Concern is growing over the power, influence, and threats to health and equity from the operations of large global consultancy firms. Collectively, these firms support a neoliberal policy environment promoting business interests ahead of public health. Global consultancy firms act as commercial determinants of health, an evolving area of research over recent years. However, this research mainly focuses on specific corporations or industry sectors, especially those which produce harmful products, including ultra-processed food, alcohol, and fossil fuels. It is therefore important to expand the focus to include large global consultancy firms and place a public health and equity lens over their operations.
    METHODS: Global consultancy firms have wide-ranging conflicts of interest. These arise from the \'revolving door\' employment strategies between their own staff and those from government and regulatory bodies. These firms also advise governments on taxation and other matters while concurrently advising corporate clients on ways to minimise taxation. They advise fossil fuel corporations while also advising governments on climate and health policies. These firms undermine the capabilities of the public sector through the outsourcing of traditional public sector roles to these private interests. Consultancy firms foster private interests through their engagement with the higher education sector, and thereby weaken the tradition of transparent management of university affairs by accountable university councils. While private consultancies cannot be blamed for all the negative consequences for health and equity caused by the problems associated with globalisation and advanced capitalism, they have played a role in amplifying them.
    CONCLUSIONS: Addressing the negative impacts of global consultancy firms will require strengthening the public sector, enforcing greater transparency, accountability, and minimising conflicts of interest. It will also demand critical thought, counter discourses, and activism to reframe the narratives supporting neo-liberal ideas of governance that are promoted in both government and business arenas.

    背景:烟草的成本是戒烟的主要原因之一。荷兰在9个月内两次提高了烟草税:2020年4月每包增加1欧元,2021年1月每包增加0.12欧元。这项研究调查了人们报告在多大程度上考虑由于即将到来的税收增加而辞职,以及它与他们年龄的关系,收入或教育水平。此外,我们研究了思考戒烟是否与戒烟意图和戒烟行为有关,以及这些关联对于两次增税是否不同。
    方法:来自国际烟草控制(ITC)荷兰调查的纵向数据,使用了队列2(N=5919个观测值;波1(2020年2月-3月):n=2051;波2(2020年9月-11月):n=1919;波3(2021年6月-7月):n=1949)。广义估计方程(GEE)回归适合于测试由于税收增加和税后增加的辞职意图之间的关联。严重的戒烟尝试,戒烟(每月≤1支香烟),以及社会人口统计学变量。
    结果:大约一半的吸烟者报告说,由于即将到来的税收增加,他们考虑戒烟(第1波=51.3%(n=1052);第2波=47.3%(n=849))。报告由于即将到来的税收增加而考虑戒烟的个人更有可能增加他们的戒烟意愿(aOR:2.00,p≤.001)或进行了严重的戒烟尝试(aOR:1.48,p≤.001)。在第2波到第3波(2021年后增加)之间尝试戒烟的人比在第1波到第2波(2020年后增加)之间尝试戒烟的人多。我们没有发现波浪和思考退出之间的相互作用效应。退出尝试,戒烟。
    结论:增税刺激人们考虑戒烟。考虑由于即将到来的税收增加而辞职与更积极的辞职意图和认真的辞职尝试有关。
    BACKGROUND: The cost of tobacco is one of the most reported reasons to quit smoking. The Netherlands increased tobacco taxes twice in the span of nine months: a €1 increase per pack in April 2020, and a €0.12 increase per pack in January 2021. This study examines to what extent people report to think about quitting due to the upcoming tax increase(s), as well as how it relates to their age, income or educational level. Additionally, we examined whether thinking about quitting was associated with quit intention and quit behaviour, and whether these associations were different for the two tax increases.
    METHODS: Longitudinal data from the International Tobacco Control (ITC) Netherlands Surveys, Cohort 2 were used (N = 5919 observations; wave 1 (February - March 2020): n = 2051; wave 2 (September - November 2020): n = 1919; wave 3 (June - July 2021): n = 1949). Generalised Estimating Equation (GEE) regressions were fit to test the associations between thinking about quitting due to the tax increase and post-tax increases in quit intention, serious quit attempts, and quitting smoking (≤ 1 cigarette a month), as well as sociodemographic variables.
    RESULTS: Circa half of the people who smoke reported thinking about quitting smoking due to the upcoming tax increase (Wave 1 = 51.3% (n = 1052); Wave 2 = 47.3% (n = 849)). Individuals who reported thinking about quitting smoking due to upcoming tax increase(s) were more likely to have increased their quit intention (aOR: 2.00, p ≤ .001) or have carried out a serious quit attempt (aOR:1.48, p ≤ .001) post-tax increase. More people attempted to quit smoking between wave 2 and 3 (post 2021 increase) than between wave 1 and 2 (post 2020 increase). We did not find an interaction effect between wave and thinking about quitting for quit intention, quit attempts, and quitting smoking.
    CONCLUSIONS: Tax increases stimulate people to think about quitting. Thinking about quitting due to an upcoming tax increase was associated with more positive quit intention and serious quit attempts.

    背景:国家食品环境政策有助于减少与饮食相关的非传染性疾病。然而,它们在荷兰的执行仍然很低。据推测,媒体可以在引发政策关注度激增方面发挥关键作用,从而塑造政治行动。这项研究的目的是通过分析各种行为者使用的论点,研究2000-2022年间荷兰报纸文章中关于食品政策的论述。
    方法:在NexisUni中进行了系统搜索,以识别2000-2022年间在七家荷兰国家报纸上发表的涵盖国家级荷兰食品环境政策的报纸文章。承保政策分为六个领域,包括食品成分,标签,促销,价格,提供和零售,并进入政策周期的四个阶段;政策制定,决策,实施,和评价。灰色文献检索用于确定2000-2022年期间实施的食品政策。描述性统计数据被用来总结政策随着时间的推移,政策类型和政策阶段。对报纸文章的随机子样本进行了解释性内容分析,以确定演员,粮食政策的观点和论点。
    结果:我们确定了896篇相关报纸文章。报纸对食品政策的报道最初很低,但在2018/2021/2022年达到顶峰。通过灰色文献检索,我们确定了6项2000-2022年实施或调整的食品政策。大多数报纸文章都报道了食品定价政策,并在政策制定阶段进行了讨论。学者(主要是支持)是最多的,食品行业(主要是反对)是引用最少的参与者。支持性论点强调了健康后果,健康不平等和集体责任,而相反的论点集中在不必要的政府干预和政策无效上。
    结论:涉及食品政策的荷兰报纸文章代表了各种参与者和论点,个人对食物选择的责任和集体责任在争论中起着核心作用。这些见解可以作为进一步研究为什么使用某些论点及其对政策关注和执行的影响的基础。
    BACKGROUND: National food environment policies can contribute to the reduction of diet-related non-communicable diseases. Yet, their implementation in the Netherlands remains low. It has been hypothesized that the media can play a pivotal role in inducing spikes in policy attention, thereby shaping political action. The aim of this study was to examine the discourse on food policies in Dutch newspaper articles between 2000-2022, by analyzing arguments used by various actors.
    METHODS: A systematic search in Nexis Uni was used to identify newspaper articles that covered national-level Dutch food environment policies published in seven Dutch national newspapers between 2000-2022. Covered policies were classified into six domains including food composition, labeling, promotion, prices, provision and retail and into the four stages of the policy cycle; policy formulation, decision-making, implementation, and evaluation. A grey literature search was used to identify food policies implemented during 2000-2022. Descriptive statistics were used to summarize coverage of policies over time, policy type and policy stage. An interpretive content analysis was performed on a random subsample of the newspaper articles to determine the actors, viewpoints and arguments of the food policies.
    RESULTS: We identified 896 relevant newspaper articles. The coverage of food policies in newspapers was initially low but peaked in 2018/2021/2022. Through grey literature search we identified 6 food policies which were implemented or adjusted between 2000-2022. The majority of the newspaper articles reported on food pricing policies and were discussed in the policy formulation stage. Academics (mainly supportive) were the most and food industry (mostly opposing) the least cited actors. Supportive arguments highlighted health consequences, health inequalities and collective responsibility, whereas opposing arguments focused on unwanted governmental interference and ineffectiveness of policies.
    CONCLUSIONS: Dutch newspaper articles covering food policies represented a variety of actors and arguments, with individual versus collective responsibility for food choices playing a central role in the arguments. These insights may serve as a basis for further research into why certain arguments are used and their effect on policy attention and implementation.

    税收减免和激励措施用于鼓励私营卫生部门提供有利于社区卫生的服务。这项研究的目的是探讨与纳税有关的问题,提供的激励措施,投资回报,实践满意,以及2021年在哈考特港参加会议的私人健康从业者的计划。
    在哈考特港的两次全国性活动中进行了描述性横断面研究,河流州,尼日利亚十月和2021年12月,在会议与会者中使用自我管理问卷。使用IBM社会科学统计软件包(SPSS)20.0版分析获得的数据,并在表中显示。
    共有一百六十六(166)名受访者参与了这项研究。104名(62.7%)受访者认为他们经历了政府机构的多重征税。大多数受访者向各级政府缴纳了至少五万及以上的税款。一百四十二(85.5%)的受访者认为,他们没有从政府那里获得任何私人医疗业务的激励。53人(31.9%)不满意,55(33.1%)受访者设法在商业环境中生存。
    尼日利亚的私人医疗从业者经历多重征税和缺乏政府激励措施。对投资回报的不满是普遍存在的。因此,需要进行包容性的卫生部门改革,以部分减少人才外流的可能性。
    UNASSIGNED: Tax relief and incentives are utilized to encourage the private health sector to provide services that are advantageous to community health. The aim of this study was to explore the issues related to taxes paid, incentives provided, returns on investment, satisfaction with practice, and plans of private health practitioners who were conference attendees in Port Harcourt in 2021.
    UNASSIGNED: A descriptive cross-sectional study was carried out at two national events in Port Harcourt, Rivers State, Nigeria in October, and December 2021, among conference attendees using self-administered questionnaires. Data obtained was analyzed using the IBM Statistical Package for the Social Sciences (SPSS) version 20.0 and presented in tables.
    UNASSIGNED: A total of one hundred and sixty-six (166) respondents were involved in the study. One hundred and four (62.7%) respondents believed they experienced multiple taxation from agencies of government. Most respondents paid at least fifty thousand and above as taxes to various levels of government. One hundred and forty-two (85.5%) respondents believed they did not receive any incentive from governments for their private health businesses. Fifty-three (31.9%) were not satisfied, while55 (33.1%) respondents were managing to survive in the business environment.
    UNASSIGNED: Private healthcare practitioners in Nigeria experience multiple taxation and a lack of incentives from governments. Dissatisfaction with the return on investment is prevalent. Inclusive health sector reform that will partly reduce the potential for brain drain is therefore needed.

    背景:近年来,西班牙的烟草税出现了倒退,其Tobacconomics税收计分卡从2014年的3.9分(满分5分)下降到2020年的2.625分。这项研究的目的是对这种恶化背后的原因进行详细分析,并确定扭转这种趋势的可能方法。
    方法:2014-2022年对制造的卷烟(FM)和卷制烟草(RYO)市场的回顾性分析,包括税收结构/税率,负担能力,不同产品的零售价格差距,以及与邻国的价格差异。到2028年的市场水平模拟模型研究了各种税收政策方案对吸烟率的影响,避免过早死亡,吸烟强度,产品替代,政府收入,销售,和行业利润。
    结果:在过去8年中,在通货膨胀和收入增长的背景下缺乏税收增加,这意味着FM和RYO的可负担性提高了13%,20个FM和RYO棒之间的恒定差异为2欧元,西班牙和邻国法国之间的价格差距扩大了。对两种现实的改革方案进行建模,以减少/消除FM和RYO之间的价格差距,这表明政府收入大幅增加,吸烟者减少了700,000,过早死亡人数减少了210,000。
    结论:当前欧盟关于烟草税的立法为急需的烟草税改革留下了充足的空间。为了公共卫生和经济,西班牙应该提高最低消费税。这不仅能拯救生命,也为政府带来了急需的收入。
    结论:西班牙对烟草税的立场最近有所恶化。这项研究认为,在通货膨胀的背景下,历届政府未能提高最低税收,这使得烟草产品更容易负担得起。并量化了如果当局在现实范围内紧急提高吸烟率和消费税收入的改善。西班牙是欧洲国家的代表,在这些国家,政府的不作为已经过时了最低烟草税。鉴于欧盟烟草税指令的修订推迟,这项研究强调了在现有法律框架内单方面采取行动的必要性。
    BACKGROUND: In recent years tobacco taxation in Spain has regressed, with its Tobacconomics tax scorecard falling from 3.9 points (out of 5) in 2014, to only 2.625 in 2020. The objective of this research is to provide a detailed analysis of the causes behind this deterioration and identify possible ways forward for reversing this trend.
    METHODS: A retrospective 2014-2022 analysis of manufactured cigarettes (FM) and roll-your-own tobacco (RYO) markets including tax structure/rates, affordability, retail price gaps across products, and price differentials with bordering countries. A market level simulation model to 2028 studied the impact of various tax policy scenarios on smoking prevalence, premature deaths averted, smoking intensity, product substitution, government revenue, sales, and industry profit.
    RESULTS: A lack of tax increases in a context of inflation and income growth during the past 8 years means FM and RYO have become 13% more affordable, with a constant differential of €2 between 20 FM and RYO sticks, and the price gap between Spain and neighbouring France increased. Modelling of two realistic reform scenarios that reduce/eliminate the price gap between FM and RYO suggest substantial increases in government revenues and up to 700,000 fewer smokers and 210,000 fewer premature deaths.
    CONCLUSIONS: Current European Union legislation on tobacco taxes leaves ample room for much needed tobacco tax reform. For the sake of both public health and the economy, Spain should increase its Minimum Excise Tax. This would not only save lives, but also bring much needed revenue for the government.
    CONCLUSIONS: The stance of Spain on tobacco taxes has deteriorated recently. This study argues that the failure of successive governments to raise minimum taxes in an inflationary context has made tobacco products more affordable, and quantifies the improvements in smoking prevalence and excise revenue that would accrue if the authorities act urgently increasing rates within realistic limits.Spain is representative of European countries where government inaction has rendered minimum tobacco taxes obsolete. Given the postponement of the revision of the European Union Tobacco Tax Directive, this study highlights the need to act unilaterally within the existing legal framework.

    一些国家已经开始征收公共卫生产品税,目的是减少不健康食品的绝对消费量并解决肥胖问题。这项研究旨在评估2011年引入的匈牙利公共卫生产品税的长期影响。为了实现这一点,分析了一个独特的消费者购买数据集,以检查2010年至2018年2,000个家庭的代表性样本中的每日快速消费品购买情况.结果表明,税收已经充分反映在居民消费价格中。最初观察到消费下降,与匈牙利和其他国家的经验一致。然而,随着时间的推移,数据表明,随着可支配收入的增长,经济复苏甚至增长。征税产品占快速消费品购买总额的比例从2010年的5.9%(95%CI:5.7%至6.0%)上升至2018年的7.4%(95%CI:7.3%至7.6%)。此外,由于低收入家庭在总支出中的支出比例更高,该税加剧了不平等。尽管短期内对不健康食品征税已被证明是有效的,从长远来看,它们可能不足以减少整体消费,特别是随着可支配收入的增加。总之,实施复杂的干预措施对于实现饮食习惯的可持续积极变化是必要的。
    Several countries have introduced public health product taxes with the objective of reducing the absolute amount of consumption of unhealthy food and tackling obesity. This study aims to estimate the long-term impact of the Hungarian public health product tax introduced in 2011. To achieve this, a unique consumer purchase dataset was analysed to examine daily fast-moving consumer goods purchases from a representative sample of 2,000 households from 2010 to 2018. The results indicate that the tax has been fully reflected in consumer prices. A decline in consumption was observed initially, consistent with previous experiences in Hungary and other countries. However, over time, the data suggests a recovery and even an increase in line with the growth of disposable income. The proportion of taxed products in total fast-moving consumer goods purchases increased from 5.9 % (95 % CI: 5.7 % to 6.0 %) in 2010 to 7.4 % (95 % CI: 7.3 % to 7.6 %) in 2018. Furthermore, the tax has contributed to increased inequality as low-income households spend a higher proportion of their total expenditure on it. Although taxes on unhealthy foods have proven effective in the short-term, they may not be adequate for reducing overall consumption in the long-term, particularly as disposable income increases. In conclusion, implementing complex interventions is necessary to achieve sustainable positive changes in dietary habits.

    背景:在亚洲环境中,对含糖饮料(SSB)征税的潜在健康影响尚未得到充分研究。这项研究旨在通过支付意愿(WTP)调查和模拟分析,评估SSB税收对香港肥胖/超重和2型糖尿病(T2DM)患病率的影响。
    方法:于2020年5月至6月对1000名成年人进行了随机电话调查。我们使用了一种或有估值方法来评估个人在四种纳税情况下对SSB的WTP(5%,10%,40%,和当前市场价格的50%)。基于WTP,我们进行了一项模拟分析,以预测10年模拟期内SSB购买的变化以及肥胖/超重和T2DM患病率的相关降低.
    结果:当引入5%和10%的税率时,大约三分之一的人口不愿意维持他们的SSB购买。我们的模拟表明,当引入更高的税率时,肥胖/超重和糖尿病的患病率逐渐下降,并且下降更为明显。10%的税收导致第六年每10万人口平均减少1532.7例超重/肥胖,而T2DM患病率下降267.1(0.3%)。
    结论:这项研究强调了在富裕的亚洲环境中,SSB税对购买行为和健康结果的影响,对成年人口的影响更为明显。预计这些发现将为决策者做出有关SSB有效和公平税率的决策提供信息。
    BACKGROUND: The potential health effects of taxing sugar-sweetened beverages (SSBs) has been insufficiently examined in Asian contexts. This study aimed to assess the impact of SSB taxation on the prevalence of obesity/overweight and type 2 diabetes mellitus (T2DM) in Hong Kong using a willingness-to-pay (WTP) survey and simulation analysis.
    METHODS: A random telephone survey was conducted with 1000 adults from May to June 2020. We used a contingent valuation approach to assess individuals\' WTP for SSBs under four tax payment scenarios (5%, 10%, 40%, and 50% of the current market price). Based on the WTP, a simulation analysis was conducted to project changes in SSB purchase and associated reductions in the prevalence of obesity/overweight and T2DM over a 10-year simulation period.
    RESULTS: When 5% and 10% taxation rates were introduced, approximately one-third of the population were unwilling to maintain their SSB purchase. Our simulation demonstrated a gradual decline in the prevalence of obesity/overweight and diabetes with a more pronounced decrease when higher taxation rates were introduced. 10% taxation resulted in a mean reduction of 1532.7 cases of overweight/obesity per 100 thousand population at the sixth year, while T2DM prevalence decreased by 267.1 (0.3%).
    CONCLUSIONS: This study underscores the effects of an SSB tax on purchase behaviors and health outcomes in an affluent Asia setting, with a more pronounced influence on adult population. These findings are expected to inform policymakers in making decisions regarding an effective and equitable tax rate on SSBs.
