Accelerating the Worldwide Adoption of Sugar-Sweetened Beverage Taxes: Strengthening Commitment and Capacity Comment on "The Untapped Power of Soda Taxes: Incentivizing Consumers, Generating Revenue, and Altering Corporate Behavior"

Political economy analysis of health taxes (tobacco, alcohol drink and sugar-sweteened beverage): qualitative study of three provinces in Indonesia

OBJECTIVE

Efforts to implement health tax policies to control the consumption of harmful commodities and enhance public health outcomes have garnered substantial recognition globally. However, their successful adoption remains a complex endeavour. This investigates the challenges and opportunities surrounding health tax implementation, with a particular focus on subnational government in Indonesia, where the decentralisation context of health tax remains understudied.

DESIGN

Employing a qualitative methodology using a problem-driven political economy analysis approach.

SETTING

We are collecting data from a total of 12 focus group discussions (FGDs) conducted between July and September 2022 in three provinces-Lampung, Special Region of/Daerah Istimewa Yogyakarta and Bali, each chosen to represent a specific commodity: tobacco, sugar-sweetened beverages (SSBs) and alcoholic beverages-we explore the multifaceted dynamics of health tax policies.

PARTICIPANT

These FGDs involved a mean of 10 participants in each FGD, representing governmental institutions, non-governmental organisations and consumers.

RESULTS

Our findings reveal that health tax policies have the potential to contribute significantly to public health. Consumers understand tobacco's health risks, and cultural factors influence both tobacco and alcohol consumption. For SSBs, the consumers lack awareness of long-term health risks is concerning. Finally, bureaucratic complexiting and decentralised government hinder implementation for all three commodities.

CONCLUSION

Furthermore, this study underscores the importance of effective policy communication. It highlights the importance of earmarking health tax revenues for public health initiatives. It also reinforces the need to see health taxes as one intervention as part of a comprehensive public health approach including complementary non-fiscal measures like advertising restrictions and standardised packaging. Addressing these challenges is critical for realising the full potential of health tax policies.

Challenges to the development of taxation policies for sugar-sweetened beverages in Colombia

Frequent consumption of sugar sweetened beverages (SSB) is related to the risks of developing overweight, obesity, cavities, diabetes and other diseases. Policies to significantly increase taxes on SSB have proven to be effective in reducing their consumption. The political debate on implementing these taxes in Colombia shows a series of barriers to placing this policy on the political agenda, and therefore, to its approval. This work analyses the political process involved in the struggle for the approval of an SBB tax in Colombia, as well as barriers and opportunities to putting it on the political agenda. This is done through a policy analysis with three research methods: a documentary analysis, political mapping of actors and semistructured interviews with key actors. Among the main findings, we have that actors who are in favour of the SSB tax stated that it is needed due to the health problems caused by SSB consumption, while those who opposed it argue that Colombia regulations are sufficient and already inform and educate consumers on excessive sugar consumption and its health implications. The Colombian political context is a barrier to SSB taxation, as the government favours and has a close connection with the food and SSB industry. In short, the policy issue has been reaching the agenda intermittently throughout the years. Nevertheless, new opportunities are arising after the COVID-19 pandemic and the 2022 administrative changes and further efforts from policy entrepreneurs are required to make this initiative progress in the political agenda.

Health taxes in Indonesia: a review of policy debates on the tobacco, alcoholic beverages and sugar-sweetened beverage taxes in the media

INTRODUCTION

One of the WHO's 'best buys' in controlling non-communicable diseases and their risk factors is to impose health taxes. While the Indonesian political process inhibits the implementation of health tax policy, studies to discuss the issue remain limited.

METHODS

We employed media analysis to document health tax policy dynamics, for example, the changes in policy timeline and key actors' statements. We conducted an article search in the Open-Source Intelligence database using appropriate terminology on three commodities, for example, tobacco, alcoholic beverages and sugar-sweetened beverages (SSB).

RESULTS

Throughout the 15 years of implementation (2007-2022), tobacco has received the most policy attention compared with the other two commodities. This is mainly related to the increasing tariff and reforming the tax structure. As Indonesia is a Muslim-majority country, alcohol consumption is low, and a tax on alcoholic beverages was nearly unchanging and lacked media coverage. Ministry of Finance (MoF) officials are key opinion leaders often cited in the media for health taxes. MoF's support for health taxes is important to pass and implement health taxes. While SSB taxation is emerging, key opinion leaders' media statements imply policy contestation, leading to delayed implementation. The policy debates on tobacco taxation implied election years as a major challenge for health tax passages. During the political years, anti-health tax arguments emerged from politicians. While the political contestation on SSB concluded that accentuating the health tax arguments in favour of public health generates the strongest opposition against taxation from the industry.

CONCLUSIONS

Politics of tobacco tax implementation are complex-compared with the other two commodities. The political context drives the divided views among policy-makers. Policy recommendations include generating public allies with key religious opinion leaders, continuing capacity building for politicians and Ministry of Health, and generating evidence-based arguments in favour of public health for MoF.

Why has the taxing policy on sugar sweetened beverages not reduced their purchase in Iranian households?

Objective

This study aimed at analyzing the effectiveness of the policy of taxing Sugar-Sweetened Beverages (SSBs) on their purchases during the last decade in Iranian households.

Methods

The present mixed method study was done in 2017 in four phases: (1) A meta-review of the fiscal policies during the last decade, (2) Collecting existing data on soft drinks' production, price, and household expenditure during the last decade, (3) Conducting 19 semi-structured interviews with key informants, and (4) Facilitating a national meeting to achieve a consensus on the recommendations and future implications.

Results

Document reviews showed that based on the Permanent Provisions of National Development Plans of Iran, the Ministry of Health and Medical Education (MOHME) should announce the list of health threatening products to increase taxation for them. The government is allowed to impose taxes on domestically produced and imported SSBs. The average household expenditure on SSBs increased in the rural and urban households of Iran during 2006-2016 in spite of taxation. In the different key informants' opinion, only value-added tax (VAT) was implemented among different fiscal policies, and the other parts, including tax and tolls were debated.

Conclusion

The present research findings further proposed some suggestions for increasing the effectiveness of financial policies in reducing the prevalence of NCDs in Iran.

A review of front-of-pack nutrition labelling in Southeast Asia: Industry interference, lessons learned, and future directions

Front-of-pack nutrition labelling is an evidence-based nutrition intervention that is recommended by the World Health Organization and other health agencies as an effective non-communicable disease prevention strategy. To date, the types of front-of-pack labels that have been identified as being most effective have yet to be implemented in Southeast Asia. This has been partly attributed to extensive industry interference in nutrition policy development and implementation. This paper outlines the current state of food labelling policy in the region, describes observed industry interference tactics, and provides recommendations for how governments in Southeast Asia can address this interference to deliver best-practice nutrition labelling to improve diets at the population level. The experiences of four focal countries - Malaysia, Thailand, the Philippines, and Viet Nam - are highlighted to provide insights into the range of industry tactics that are serving to prevent optimal food labelling policies from being developed and implemented.

Health Taxes on Tobacco, Alcohol, Food and Drinks in Low- and Middle-Income Countries: A Scoping Review of Policy Content, Actors, Process and Context

BACKGROUND

Taxation of tobacco, food, alcohol and other beverages has gained renewed attention in responding to non-communicable diseases (NCDs). While largely built on evidence from high-income countries (HICs), the projected economic and health benefits of these measures have increased calls for their use in price-sensitive low- and middle-income countries (LMICs). However, uptake has been sporadic and there remains little research on why and how LMICs utilise fiscal measures in response to NCDs.

METHODS

This scoping review analyses factors influencing the design and implementation of health-related fiscal measures in LMICs. Utilising Arksey and O'Malley's scoping review methodology and Walt and Gilson's policy triangle, we considered the contextual, procedural, content and stakeholder-related factors that influenced measures.

RESULTS

We identified 75 papers focussing on health-related fiscal measures, with 47 (63%) focused on tobacco, 5 on alcohol, 6 on soft drink and 4 studies on food-related fiscal regulation. Thirteen papers analysed multiple measures and most papers (n = 66, 88%) were less than a decade old. Key factors enabling the design and implementation of measures included localised health and economic evidence, policy championing, inter-ministerial support, and global or regional momentum. Impeding factors encompassed negative framing and retaliation by industry, vested interests and governmental policy disjuncture. Aligning with theoretic insights from the policy triangle, findings consistently demonstrated that the interplay between factors - rather than the presence or absence of particular factors - has the most profound impact on policy implementation.

CONCLUSION

Given the growing urgency to address NCDs in LMICs, this review highlights the need for recognition and rigorous exploration of political economy factors influencing the design and implementation of fiscal measures. Broader LMIC-specific empirical research is needed to overcome an implication noted in much of the literature: that mechanisms used to enact tobacco taxation are universally applicable to measures targeting foods, alcohol and other beverages.

Sugar-sweetened beverage tax implementation processes: results of a scoping review

Taxing sugar-sweetened beverages (SSB) is seen as a win–win situation for governments. It is argued that SSB taxes are relatively easy to implement from a practical perspective compared to for example other nutrition policies. However, the implementation of SSB taxation laws does not happen by itself. Therefore, this work examines implementation processes for SSB taxation in terms of (1) pre-implementation context, (2) taxation instruments used and (3) interactions in the implementation process. Ten databases and grey literature were systematically searched for studies reporting on SSB taxation implementation processes up to February 2020. All studies (N = 1248) were screened independently by two reviewers according to predefined criteria. The selection of variables to be extracted was based on the policy cycle heuristic and informed by intervention implementation research. Information on the process of implementing SSB taxation is limited. Only six cases based on three publications were identified, indicating a gap in this research area. SSB taxation implementation was accomplished by hiring a subcontractor for the implementation or using pre-existing tax collection structures. Political and public support within the implementation process seems to be supportive for the city of Berkeley and for Portugal but was not reported for the Pacific Islands. However, the existing data are very limited, and further research on SSB taxation implementation processes is needed to determine whether the aim of the policy and the envisaged outcome are linked in practice.

Stakeholder views on taxation of sugar-sweetened beverages and its adoption in the Netherlands

An increasing number of governments worldwide have introduced a tax on sugar-sweetened beverages (SSB) for public health. However, the adoption of such a policy is still debated in many other countries, such as in the Netherlands. We investigated Dutch stakeholder views on taxation of SSB and perceived barriers and facilitators to its adoption in the Netherlands. Semi-structured interviews were conducted in 2019 with 27 stakeholders from health and consumer organizations, health professional associations, trade associations, academia, advisory bodies, ministries and parliamentary parties. Data were analysed using a thematic content approach. The findings reveal that, between and within sectors, stakeholders expressed contradictory views on the effectiveness, appropriateness and (socio)economic effects of an SSB tax. Perceived barriers to the adoption of an SSB tax in the Netherlands included an unfavourable political context, limited advocacy for an SSB tax, a strong lobby against an SSB tax, perceived public opposition, administrative load and difficulties in defining SSB. Perceived facilitators to its adoption included an increasing prevalence of overweight, disappointing results from voluntary industry actions, a change of government, state budget deficits, a shift in public opinion, international recommendations and a solid legal basis. In conclusion, this study shows that several challenges remain to be overcome for the adoption of an SSB tax in the Netherlands. Similar research on stakeholder views in other countries may further inform SSB tax policy processes.

The impact of taxing sugar-sweetened beverages on cola purchasing in Catalonia: an approach to causal inference with time series cross-sectional data

Sugar-sweetened beverage (SSB) taxes related to the quantity of sugar have appeared as a popular regulatory tool around the world during the last decade showing important variations in their implementation and impact. We evaluated the impact of a new SSB tax implemented in Catalonia since May 1, 2017 on the purchased quantities and penetration rates of taxed and untaxed cola beverages. We use aggregate time series of cola beverages purchases in all 17 Spanish Autonomous Communities before and after the implementation of the SBB tax in Catalonia, from January 2013 to June 2019. A comparison between two different types of causal inference methods was conducted: a two-way fixed effects difference in differences model and a modified synthetic control model. Regular cola purchases decreased 12.1% and their penetration rate decreased by 1.27 points during the two post-intervention years using the preferred model. Diet cola purchases increased 17.0% and their penetration rate also increased by 1.65 points. Only regular cola results were robust to all placebo test checks. The SSB tax implemented in Catalonia in 2017 significantly reduced the volume and penetration rates of regular colas with no robust evidence for the substitution effect on diet colas.

The political economy of sugar-sweetened beverage taxation in Latin America: lessons from Mexico, Chile and Colombia

BACKGROUND

In Latin America, total sales of sugar-sweetened beverages (SSBs) continue to rise at an alarming rate. Consumption of added sugar is a leading cause of diet-related non-communicable diseases (NCDs). Coalitions of stakeholders have formed in several countries in the region to address this public health challenge including participation of civil society organizations and transnational corporations. Little is currently known about these coalitions - what interests they represent, what goals they pursue and how they operate. Ensuring the primacy of public health goals is a particular governance challenge. This paper comparatively analyses governance challenges involved in the adoption of taxation of sugar-sweetened beverages in Mexico, Chile and Colombia. The three countries have similar political and economic systems, institutional arrangements and regulatory instruments but differing policy outcomes.

METHODS

We analysed the political economy of SSB taxation based on a qualitative synthesis of existing empirical evidence. We identify the key stakeholders involved in the policy process, identified their interests, and assess how they influenced adoption and implementation of the tax.

RESULTS

Coalitions for and against the SSB taxation formed the basis of policy debates in all three countries. Intergovernmental support was critical to framing the SSB tax aims, benefits and implementation; and for countries to adopt it. A major constraint to implementation was the strong influence of transnational corporations (TNCs) in the policy process. A lack of transparency during agenda setting was notably enhanced by the powerful presence of TNCs.

CONCLUSION

NCDs prevention policies need to be supported across government, alongside grassroots organizations, policy champions and civil society groups to enhance their success. However, governance arrangements involving coalitions between public and private sector actors need to recognize power asymmetries among different actors and mitigate their potentially negative consequences. Such arrangements should include clear mechanisms to ensure transparency and accountability of all partners, and prevent undue influence by industry interests associated with unhealthy products.

Industry strategies in the parliamentary process of adopting a sugar-sweetened beverage tax in South Africa: a systematic mapping

BACKGROUND

In 2016, the South African government became the first in the African region to announce the introduction of an SSB tax based on sugar content as a public health measure to reduce obesity. This tax was introduced against the backdrop of South Africa having a large sugar production and SSB manufacturing industry, as well as very high unemployment rates. The introduction of fiscal measures, such as a SSB tax, has been met with well-coordinated and funded opposition in other countries.

METHODS

The aim of this study is to describe and analyse the arguments and strategies utilised by industry during policymaking processes to oppose regulatory actions in LMIC. This study analyses arguments and strategies used by the beverage and related industries during the public consultation phase of the process to adopt the South African SSB tax.

RESULTS

Industry opposition to the SSB tax was comprehensive and employed several tactics. First, industry underscored its economic importance and the potential job losses and other economic harms that may arise from the tax. This argument was well-received by policymakers, and similar to industry tactics employed in other middle income countries like Mexico. Second, industry discussed self-regulation and voluntary measures as a form of policy substitution, which mirrors industry responses in the US, the Caribbean and Latin America. Third, industry misused or disputed evidence to undermine the perceived efficacy of the tax. Finally, considerations for small business and their ability to compete with multi-national corporations were a unique feature of industry response.

CONCLUSIONS

Industry opposition followed both general trends, and also introduced nuanced and context-specific arguments. The industry response experienced in South Africa can be instructive for other countries contemplating the introduction of similar measures.

Ultra-processed foods and the nutrition transition: Global, regional and national trends, food systems transformations and political economy drivers

Understanding the drivers and dynamics of global ultra-processed food (UPF) consumption is essential, given the evidence linking these foods with adverse health outcomes. In this synthesis review, we take two steps. First, we quantify per capita volumes and trends in UPF sales, and ingredients (sweeteners, fats, sodium and cosmetic additives) supplied by these foods, in countries classified by income and region. Second, we review the literature on food systems and political economy factors that likely explain the observed changes. We find evidence for a substantial expansion in the types and quantities of UPFs sold worldwide, representing a transition towards a more processed global diet but with wide variations between regions and countries. As countries grow richer, higher volumes and a wider variety of UPFs are sold. Sales are highest in Australasia, North America, Europe and Latin America but growing rapidly in Asia, the Middle East and Africa. These developments are closely linked with the industrialization of food systems, technological change and globalization, including growth in the market and political activities of transnational food corporations and inadequate policies to protect nutrition in these new contexts. The scale of dietary change underway, especially in highly populated middle-income countries, raises serious concern for global health.

The drivers, trends and dietary impacts of non-nutritive sweeteners in the food supply: a narrative review

Poor diets, including excess added sugar consumption, contribute to the global burden of disease. Subsequently, many nutrition policies have been implemented to reduce added sugar intake and improve population health, including taxes, education, labelling and environmental interventions. A potential consequence of these policy actions is the substitution of added sugars with non-nutritive sweeteners (NNS) in a variety of foods and beverages. NNS are used to reduce the energy and sugar content of foods and beverages while maintaining their palatability. Evidence of the toxicological risks of NNS is inconsistent, though concerns have been raised over the potential substitution effects of ultra-processed foods containing NNS for whole foods. This review aimed to provide an overview of current NNS food supply and consumption patterns, assess added sugar-reduction policies and their impact on NNS, and determine the impact of NNS on food choice, energy intake and diet quality. NNS are widely available in a variety of products, though most commonly in carbonated beverages, dairy products, confectionery, table-top sweeteners and fruit drinks. However, the longitudinal trends of different product categories, and differences between geographies and economy-income levels, require further study. Few studies have examined NNS consumption trends globally, though an increase in NNS consumption in beverages has been observed in some regions. Research examining how the increased availability of low-sugar, NNS-containing products affects global dietary patterns is limited, particularly in terms of their potential substitution effects.

The Application of an Evidence Framework for Obesity Prevention at the Population-Level

PURPOSE OF REVIEW

To review existing frameworks for assessing the evidence of effectiveness of obesity prevention interventions, and discuss the application of a custom-developed evidence framework to inform an obesity prevention priority-setting study in Australia.

RECENT FINDINGS

There are a wide range of frameworks for grading evidence. However, most frameworks are not well suited to assess the effectiveness of obesity prevention interventions because they do not include processes to synthesise evidence from multiple study designs and outcome measures. The key features of the Obesity Prevention Evidence Assessment (OPEA) Framework are: [1] separately assessed weight-, diet- and physical activity-related outcomes; [2] consideration of the balance of evidence from multiple study types; and [3] a summary indication of the degree of certainty of intervention effectiveness. Evidence frameworks that recognise the complexities of obesity prevention research can support decision-makers in prioritising actions to address obesity alongside broader priority-setting considerations.

Coca-Cola's political and policy influence in Mexico: understanding the role of institutions, interests and divided society

In response to Mexico's burgeoning industrial epidemics of obesity and type-2 diabetes, triggered in part by sugar-sweetened carbonated beverages' ability to readily market their products and influence consumption, the government has responded through a variety of non-communicable disease (NCD) policies. Nevertheless, major industries, such as Coca-Cola, have been able to continuously obstruct the prioritization of those policies targeting the consumption, marketing and sale of their products. To better understand why this has occurred, this article introduces a political science agenda-setting framework and applies it to the case of Coca-Cola in Mexico. Devised from political science theory and subsequently applied to the case of Coca-Cola in Mexico, my framework, titled Institutions, Interests, and Industry Civic Influence (IPIC), emphasizes Coca-Cola's access to institutions, supportive presidents and industry efforts to hamper civic mobilization and pressures for greater regulation of the soda industry. Methodologically, I employ qualitative single case study analysis, combining an analysis of 26 case study documents and seven in-depth stake-holder interviews. My proposed analytical framework helps to underscore the fact that Coca-Cola's influence is not solely shaped by the corporation's increased economic importance, but more importantly, its access to politicians, institutions and strategies to divide civil society. Additionally, my proposed framework provides several real-world policy recommendations for how governments and civil society can restructure their relationship with the soda industry, such as the government's creation of laws prohibiting the industry's ability to influence NCD policy and fund scientific research.

Nutritional adequacy and dietary disparities in an adult Caribbean population of African descent with a high burden of diabetes and cardiovascular disease

The Caribbean island of Barbados has a high burden of diabetes and cardiovascular disease. Dietary habits were last described in 2005. A representative population-based sample (n = 363, aged 25-64 years) provided two nonconsecutive 24-hr dietary recalls in this cross-sectional study. Mean daily nutrient intakes were compared with the Dietary Guidelines for Americans. Subgroup differences by age, sex, and educational level were examined using logistic regression. High sugar intakes exist for both sexes with 24% (95% CIs 18.9, 30.0) consuming less than the recommended <10% of energy from added sugars (men 22%; 15.0, 31.6; women 26%; 18.9, 33.7). Sugar-sweetened beverages provide 43% (42.2%, 44.4%) of total sugar intake. Inadequate dietary fiber intakes (men 21 g, 18.2, 22.8; women 18 g, 16.7, 18.9) exist across all age groups. Inadequate micronutrient intake was found in women for calcium, folate, thiamine, zinc, and iron. Older persons (aged 45-64 years) were more likely to report adequacy of dietary fiber (OR = 2.7, 1.5, 4.8) and iron (OR = 3.0, 1.7, 5.3) than younger persons (aged 25-44). Older persons (aged 45-64 years) were less likely to have an adequate supply of riboflavin (OR = 0.4, 0.2, 0.6) than younger persons. Men were more likely to have adequate intakes of iron (OR = 13.0, 6.1, 28.2), folate (OR = 2.4, 1.3, 4.6), and thiamine (OR = 3.0, 1.5, 5.0) than women. Education was not associated with nutrient intake. The Barbadian diet is characterized by high sugar intakes and inadequate dietary fiber; a nutrient profile associated with an increased risk of obesity, type 2 diabetes, and related noncommunicable diseases.

A cross-sectional study of the public health response to non-alcoholic fatty liver disease in Europe

BACKGROUND & AIMS

Non-alcoholic fatty liver disease (NAFLD) is a growing public health problem worldwide and has become an important field of biomedical inquiry. We aimed to determine whether European countries have mounted an adequate public health response to NAFLD and non-alcoholic steatohepatitis (NASH).

METHODS

In 2018 and 2019, NAFLD experts in 29 European countries completed an English-language survey on policies, guidelines, awareness, monitoring, diagnosis and clinical assessment in their country. The data were compiled, quality checked against existing official documents and reported descriptively.

RESULTS

None of the 29 participating countries had written strategies or action plans for NAFLD. Two countries (7%) had mentions of NAFLD or NASH in related existing strategies (obesity and alcohol). Ten (34%) reported having national clinical guidelines specifically addressing NAFLD and, upon diagnosis, all included recommendations for the assessment of diabetes and liver cirrhosis. Eleven countries (38%) recommended screening for NAFLD in all patients with either diabetes, obesity and/or metabolic syndrome. Five countries (17%) had referral algorithms for follow-up and specialist referral in primary care, and 7 (24%) reported structured lifestyle programmes aimed at NAFLD. Seven (24%) had funded awareness campaigns that specifically included prevention of liver disease. Four countries (14%) reported having civil society groups which address NAFLD and 3 countries (10%) had national registries that include NAFLD.

CONCLUSIONS

We found that a comprehensive public health response to NAFLD is lacking in the surveyed European countries. This includes policy in the form of a strategy, clinical guidelines, awareness campaigns, civil society involvement, and health systems organisation, including registries.

LAY SUMMARY

We conducted a survey on non-alcoholic fatty liver disease with experts in European countries, coupled with data extracted from official documents on policies, clinical guidelines, awareness, and monitoring. We found a general lack of national policies, awareness campaigns and civil society involvement, and few epidemiological registries.

Generating political commitment for ending malnutrition in all its forms: A system dynamics approach for strengthening nutrition actor networks

Generating political commitment for ending all forms of malnutrition represents a key challenge for the global nutrition community. Without commitment, the policies, programs, and resources needed to improve nutrition are unlikely to be adopted, effectively implemented, nor sustained. One essential driver of commitment is nutrition actor network (NAN) effectiveness, the web of individuals and organizations operating within a given country who share a common interest in improving nutrition and who act collectively to do so. To inform new thinking and action towards strengthening NAN effectiveness, we use a systems dynamics theoretical approach and literature review to build initial causal loop diagrams (CLDs) of political commitment and NAN effectiveness and a qualitative group model building (GMB) method involving an expert workshop to strengthen model validity. First, a "nutrition commitment system" CLD demonstrates how five interrelated forms of commitment-rhetorical, institutional, operational, embedded, and system-wide-can dynamically reinforce or diminish one another over time. Second, we present CLDs demonstrating factors shaping NAN effectiveness organized into three categories: actor features, resources, and capacities; framing strategies, evidence, and norms; and institutional, political, and societal contexts. Together, these models generate hypotheses on how political commitment and NAN effectiveness could be strengthened in future and may provide potential starting points for country-specific conversations for doing so.

The distributional impact of taxing sugar-sweetened beverages: findings from an extended cost-effectiveness analysis in South Africa

BACKGROUND

Facing increasing obesity prevalence and obesity-related disease burden, South Africa has devised an obesity prevention strategy that includes a recently implemented tax on the sugar content of sugar-sweetened beverages (SSB). We assess the potential distributional impact (across socioeconomic groups) of this tax on type 2 diabetes mellitus (T2DM) incidence and associated mortality and its financial burden on households.

METHODS

We conducted an extended cost-effectiveness analysis of the new 10% tax on SSBs in South Africa, and estimated: the averted premature deaths related to T2DM, the financial benefits to households (out-of-pocket (OOP) medical costs and indirect costs due to productivity losses averted), the increased government tax revenues and healthcare savings for the government, all across income quintiles.

FINDINGS

A 10% SSB tax increase would avert an estimated 8000 T2DM-related premature deaths over 20 years, with most deaths averted among the third and fourth income quintiles. The government would save about South African rand (ZAR) 2 billion (US$140 million) in subsidised healthcare over 20 years; and would raise ZAR6 billion (US$450 million) in tax revenues per annum. The bottom two quintiles would bear the smallest tax burden increase (36% of the additional taxes). The bottom two income quintiles would also have the lowest savings in OOP payments due to significant subsidisation provided by government healthcare. Lastly, an estimated 32 000 T2DM-related cases of catastrophic expenditures and 12 000 cases of poverty would be averted.

CONCLUSIONS

SSB taxation would have a substantial distributional impact on obesity-related premature deaths, cost savings to the government and the financial outcomes of South Africa's population.

The politics of voluntary self-regulation: insights from the development and promotion of the Australian Beverages Council's Commitment

OBJECTIVE

To analyse the evolution of the soft drink industry's use of self-regulation as a response to obesity and examine the motivations driving its development and the strategies used to promote it to policy makers.

DESIGN

We used a data set of industry documents published by the Australian Beverages Council (ABC) between 1998 and 2016. We analysed how the ABC voiced its political motivations about self-regulation and what internal nutrition policies it developed prior to its public launch of self-regulation. We also analysed two promotional strategies: funding research and writing policy submissions.

SETTING

Australia.

RESULTS

Between 1998 and 2006, the ABC shifted from a defensive strategy that denied the role of its products in obesity to more conciliatory strategy that emphasised the role of the soft drink industry in solutions to obesity. The ABC deliberately timed the launch of its self-regulation to coincide with an international public health congress. Following its launch, the ABC funded research demonstrating the efficacy of self-regulation and wrote submissions to government nutrition policies arguing that further regulation was unnecessary.

CONCLUSIONS

The soft drink industry uses self-regulation to bolster its reputation and influence nutrition policy. Strategic timing plays a key role in the political influence of self-regulation.

"Big" Food, Tobacco, and Alcohol: Reducing Industry Influence on Noncommunicable Disease Prevention Laws and Policies Comment on "Addressing NCDs: Challenges From Industry Market Promotion and Interferences"

The food, tobacco and alcohol industries have penetrated markets in low- and middle-income countries (LMICs), with a significant impact on these countries' burden of noncommunicable diseases (NCDs). Tangcharoensathien and colleagues describe the aggressive marketing of unhealthy food, alcohol and tobacco in LMICs, as well as key tactics used by these industries to resist laws and policies designed to reduce behavioural risk factors for NCDs. This commentary expands on the recommendations made by Tangcharoensathien and colleagues for preventing or managing conflicts of interest and reducing undue industry influence on NCD prevention policies and laws, focusing on the needs of LMICs. A growing body of research proposes ways to design voluntary industry initiatives to make them more effective, transparent and accountable, but governments should also consider whether collaboration with health-harming industries is ever appropriate. More fundamentally, mechanisms for identifying, managing and mitigating conflicts of interest and reducing industry influence must be woven into - and supported by - broader governance and regulatory structures at both national and international levels.

Modelling the impact of a tax on sweetened beverages in the Philippines: an extended cost-effectiveness analysis

OBJECTIVE

To assess the potential impact of a new tax on sweetened beverages on premature deaths associated with noncommunicable diseases in the Philippines.

METHODS

In January 2018, the Philippines began imposing a tax of 6 Philippine pesos per litre (around 13%) on sweetened beverages to curb the obesity burden. Using national data sources, we conducted an extended cost-effectiveness analysis to estimate the effect of the tax on the numbers of premature deaths averted attributed to type 2 diabetes mellitus, ischaemic heart disease and stroke, across income quintiles over the period 2018-2037. We also estimated the financial benefits of the tax from reductions in out-of-pocket payments, direct medical costs averted and government health-care cost savings.

FINDINGS

The tax could avert an estimated 5913 deaths related to diabetes, 10 339 deaths from ischaemic heart disease and 7950 deaths from stroke over 20 years. The largest number of deaths averted could be among the fourth and fifth (highest) income quintiles. The tax could generate total health-care savings of 31.6 billion Philippine pesos (627 million United States dollars, US$) over 20 years, and raise 41.0 billion Philippine pesos (US$ 813 million) in revenue per annum. The poorest quintile could bear the smallest tax burden increase (14% of the additional tax; 5.6 billion Philippine pesos) and have the lowest savings in out-of-pocket payments due to relatively large health-care subsidies. Finally, we estimated that 13 890 cases of catastrophic expenditure could be averted.

CONCLUSION

The new sweetened beverage tax may help to reduce obesity-related premature deaths and improve financial well-being in the Philippines.
