A systematic scoping review evaluating sugar-sweetened beverage taxation from a systems perspective. NATURE FOOD 2023; 4:986-995.

Abstract
Systems thinking can reveal surprising, counterintuitive or unintended reactions to population health interventions (PHIs), yet this lens has rarely been applied to sugar-sweetened beverage (SSB) taxation. Using a systematic scoping review approach, we identified 329 papers concerning SSB taxation, of which 45 considered influences and impacts of SSB taxation jointly, involving methodological approaches that may prove promising for operationalizing a systems informed approach to PHI evaluation. Influences and impacts concerning SSB taxation may be cyclically linked, and studies that consider both enable us to identify implications beyond a predicted linear effect. Only three studies explicitly used systems thinking informed methods. Finally, we developed an illustrative, feedback-oriented conceptual framework, emphasizing the processes that could result in an SSB tax being increased, maintained, eroded or repealed over time. Such a framework could be used to synthesize evidence from non-systems informed evaluations, leading to novel research questions and further policy development.

Curr Diab Rep 2023; 23:265-275. [PMID: 37695402 DOI: 10.1007/s11892-023-01519-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Accepted: 07/24/2023] [Indexed: 09/12/2023]
Abstract
PURPOSE OF REVIEW Taxes on sugary drinks and foods have emerged as a key strategy to counteract the alarming levels of diabetes worldwide. Added sugar consumption from industrialized foods and beverages has been strongly linked to type 2 diabetes. This review provides a synthesis of evidence on how taxes on sugary products can influence the onset of type 2 diabetes, describing the importance of the different mechanisms through which the consumption of these products is reduced, leading to changes in weight and potentially a decrease in the incidence of type 2 diabetes. RECENT FINDINGS Observational studies have shown significant reductions in purchases, energy intake, and body weight after the implementation of taxes on sugary drinks or foods. Simulation studies based on the association between energy intake and type 2 diabetes estimated the potential long-term health and economic effects, particularly in low- and middle-income countries, suggesting that the implementation of sugary food and beverage taxes may have a meaningful impact on reducing type 2 diabetes and complications. Public health response to diabetes requires multi-faceted approaches from health and non-health actors to drive healthier societies. Population-wide strategies, such as added sugar taxes, highlight the potential benefits of financial incentives to address behaviors and protective factors to significantly change an individual's health trajectory and reduce the onset of type 2 diabetes worldwide, both in terms of economy and public health.

Tax on sugary drinks and trends in daily soda consumption by family affluence: an international repeated cross-sectional survey among European adolescents. Am J Clin Nutr 2023; 117:576-585. [PMID: 36775689 DOI: 10.1016/j.ajcnut.2023.01.011] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/01/2022] [Revised: 01/04/2023] [Accepted: 01/10/2023] [Indexed: 01/15/2023] Open
Abstract
BACKGROUND The WHO recommends soda taxes to reduce sugar consumption, but the effect across socioeconomic groups is unclear. OBJECTIVES We assessed 16-y trends in daily soda consumption among adolescents in 4 European countries with a soda tax and 5 comparison countries, by family affluence. METHODS Five rounds of the international "Health Behaviour in School-Aged Children" school-based survey were used (school years 2001/2002 to 2017/2018, repeated cross-sectional design). Finland, France, Belgium, and Portugal introduced or updated a soda tax during this period. For comparison, we selected 5 neighboring countries without such a tax. Nationally representative samples of adolescents aged 13 and 15 y (n = 165,521; 51.2% girls) completed a standardized questionnaire, including a question on soda consumption frequency. Using the family affluence scale (FAS), we categorized adolescents into lower-, middle- or higher-affluent groups. Changes in daily soda consumption were assessed in each country independently. RESULTS Before taxation, daily soda consumption was more likely among lower-affluent adolescents in France and Belgium (P < 0.001, socioeconomic inequalities) and was similar across FAS groups in Finland and Portugal (no inequalities). After the tax, daily soda consumption was reduced across all FAS groups in Finland, Belgium, and Portugal (Pinteractions ≥ 0.33). In France, a posttax decrease was observed only among lower-affluent adolescents (ORlower, 0.76; 95% CI: 0.60, 0.96; reduced inequalities). During the same periods, socioeconomic patterns remained stable in 3 comparison countries (Pinteractions ≥ 0.38), and larger reductions in daily soda consumption were observed among middle- or higher-affluent adolescents compared with lower-affluent adolescents in the remaining 2 comparison countries (Pinteractions ≤ 0.08, increased inequalities). CONCLUSIONS Socioeconomic patterns did not change after the tax implementation in 3 out of 4 countries, and socioeconomic inequalities were reduced in France. Taxing sodas might be an effective measure to attenuate, or at least not exacerbate, socioeconomic inequalities in adolescent daily soda consumption. Am J Clin Nutr 20XX;xx:xx-xx.

Abstract
Strong sugary drink taxes are effective at reducing sugary drinks consumption. In response, the sugary drinks industry employs various marketing strategies to undermine the taxes to protect and maintain its customer base. In their recent article in this journal, Forde et al present a framework for understanding how sugary drinks companies use marketing for this purpose. In this commentary, we reflect on this framework by drawing from recent experiences of sugary drinks industry marketing responses. Further, we review the global evidence on the instrumental role that strategic communication can play in protecting strong taxes from industry responses. We make a case for strategic communication as a vital tool in promoting and protecting sugary drinks tax proposals, both prior to and after their introduction.

PLOS GLOBAL PUBLIC HEALTH 2023; 3:e0001219. [PMID: 36963015 PMCID: PMC10021346 DOI: 10.1371/journal.pgph.0001219] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 04/19/2022] [Accepted: 11/22/2022] [Indexed: 06/18/2023]
Abstract
BACKGROUND Sugar sweetened beverage (SSB) taxes are a promising strategy to decrease SSB consumption, and their inequitable health impacts, while raising revenue to meet social objectives. In 2016, San Francisco passed a one cent per ounce tax on SSBs. This study compared SSB consumption in San Francisco to that in San José, before and after tax implementation in 2018. METHODS & FINDINGS A longitudinal panel of adults (n = 1,443) was surveyed from zip codes in San Francisco and San José, CA with higher densities of Black and Latino residents, racial/ethnic groups with higher SSB consumption in California. SSB consumption was measured at baseline (11/17-1/18), one- (11/18-1/19), and two-years (11/19-1/20) after the SSB tax was implemented in January 2018. Average daily SSB consumption (in ounces) was ascertained using the BevQ-15 instrument and modeled as both continuous and binary (high consumption: ≥6 oz (178 ml) versus low consumption: <6 oz) daily beverage intake measures. Weighted generalized linear models (GLMs) estimated difference-in-differences of SSB consumption between cities by including variables for year, city, and their interaction, adjusting for demographics and sampling source. In San Francisco, average SSB consumption in the sample declined by 34.1% (-3.68 oz, p = 0.004) from baseline to 2 years post-tax, versus San José which declined 16.5% by 2 years post-tax (-1.29 oz, p = 0.157), a non-significant difference-in-differences (-17.6%, adjusted AMR = 0.79, p = 0.224). The probability of high SSB intake in San Francisco declined significantly more than in San José from baseline to 2-years post-tax (AOR[interaction] = 0.49, p = 0.031). The difference-in-differences of odds of high consumption, examining the interaction between cities, time and poverty, was far greater (AOR[city*year 2*federal poverty level] = 0.12, p = 0.010) among those living below 200% of the federal poverty level 2-years post-tax. CONCLUSIONS Average SSB intake declined significantly in San Francisco post-tax, but the difference in differences between cities over time did not vary significantly. Likelihood of high SSB intake declined significantly more in San Francisco by year 2 and more so among low-income respondents.

Abstract
Introduction Both the World Health Organization and the Lancet Series on Adolescent nutrition recommend that governments adopt fiscal policies to combat diet-related non-communicable diseases (NCDs). However, rigorous, systematic evidence regarding the effects of these interventions is lacking. Methods We synthesize the available evidence regarding the impacts of taxes and subsidies that directly affect consumer prices on availability and accessibility of foods and beverages, purchasing behavior, diet quality, health and well-being outcomes as well as considerations for implementation, sustainability and equity. Results Our initial search returned 2,113 de-duplicated studies, and ultimately 24 impact evaluations and two systematic reviews met final eligibility criteria and represented unique evaluations. Our meta-analysis of these studies suggests that taxes may decrease purchases of taxed beverages (SMD = -0.14 [95% CI: -0.29 to -0.07], n = 15). Results should be interpreted cautiously due to considerable heterogeneity (Q(14) = 335.19, p = 0.01,τ ^ 2 = 0.03 , I 2 = 95.82%). Discussion The evidence base is too limited to draw conclusions about the effects of taxes on beverages and calorie-dense foods on purchases, or on the effects of subsidies on purchasing or diet quality. Overall, the evidence base is inconclusive on whether fiscal policies can meaningfully influence the availability and accessibility of foods and beverages, diet quality, and health outcomes. Policymakers implementing fiscal policies should consider information campaigns on health benefits and health risks associated with certain food and beverage consumption. For taxes, exposure to health information may amplify signaling effects of taxes and reduce avoidance behaviors, such as cross-border shopping. Future evaluations should diversify data sources to better understand impacts on diet and health outcomes.

Abstract
A growing evidence base indicates that sugar-sweetened beverage (SSB) taxes are an effective tool to help reduce excess sugar intake. The effects of SSB taxes and the mechanisms which underlie them, however, are dependent on a number of interrelated factors such as policy design and responses of industry and consumers. Forde and colleagues contribute to unpacking these mechanisms by exploring the way in which the UK's Soft Drinks Industry Levy (SDIL) shaped the four Ps of soft drinks marketing: product, price, placement, and promotion. This commentary builds on the authors' insights by connecting them to existing knowledge on corporate political activity and the commercial determinants of health (CDOH) more broadly. Specifically, I discuss the risk that an industry framing of regulation-induced marketing changes as a voluntary step towards corporate responsibility undermines the need for government intervention to address obesity in other contexts and countries. I conclude by arguing that the public health community would benefit from considering marketing responses to regulation alongside industry narratives about these changes.

Sixteen-year trends in adolescent consumption of sugar-sweetened soda in six European countries with a soda tax and comparison countries: a repeated cross-sectional survey analysis. Public Health Nutr 2022; 26:1-12. [PMID: 36321519 PMCID: PMC9989715 DOI: 10.1017/s1368980022002361] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/18/2022] [Revised: 09/27/2022] [Accepted: 10/20/2022] [Indexed: 11/07/2022]
Abstract
OBJECTIVE To examine changes in the proportions of daily, weekly and occasional consumers of sugar-sweetened soda in six European countries that introduced/updated a tax between 2001-2002 and 2017-2018 and in neighbouring comparison countries (without a tax). DESIGN Repeated cross-sectional surveys. SETTING Health Behaviour in School-aged Children study, spanning five survey years (school years 2001-2002 to 2017-2018). PARTICIPANTS Nationally representative samples of 13-year- and 15-year-old adolescents (n 236 623, 51·0 % girls). RESULTS Tax sizes (€0·02/l to €0·22/l) and pre-tax soda consumption were heterogeneous across countries. Prevalence of daily soda consumption reduced in the survey year following tax implementation in Latvia (from 17·9 to 11·9 %, P = 0·01), Finland (4·2 to 2·5 %, P = 0·001), Belgium (35·1 to 27·8 %, P < 0·001) and Portugal (17·4 to 14·9 %, P = 0·02), but not in Hungary (29·8 to 31·3 %, P = 0·47) or France (29·4 to 28·2 %, P = 0·27). However, reductions were similar (Finland) or smaller (Belgium, Portugal) than those in the comparison countries, except in Latvia where the reduction was larger (Pinteraction < 0·001). Prevalence of weekly soda consumption remained stable (Finland, Hungary and France) or increased (Latvia, Belgium); only Portugal experienced a decline (P < 0·001), which was larger than in the comparison country (Pinteraction < 0·001). Prevalence of occasional soda consumption (<1x/week) did not rise after implementation of the tax in Latvia, Finland, Hungary, France or Belgium, or the rise was similar to the comparison country in Portugal (Pinteraction = 0·15). CONCLUSIONS Countries with a soda tax did not experience larger beneficial changes in post-tax adolescent consumption frequency of soda than comparison countries. Further studies, with different taxation types, are needed in the adolescent population.

Abstract
OBJECTIVES We aimed to identify when and how integration should take place within evaluations of complex population health interventions (PHIs). STUDY DESIGN Descriptive analytical approach. METHODS We draw on conceptual insights that emerged through (1) a working group on integration and (2) a diverse range of literature on case studies, small-n evaluations and mixed methods evaluation studies. RESULTS We initially sought techniques to integrate analyses at the end of a complex PHI evaluation. However, this conceptualization of integration proved limiting. Instead, we found value in conceptualizing integration as a process that commences at the beginning of an evaluation and continues throughout. Many methods can be used for this type of integration, including process tracing, realist evaluation, congruence analysis, general elimination methodology/modus operandi, pattern matching and contribution analysis. Clearly signposting when integrative methods should commence within an evaluation should be of value to the PHI evaluation community, as well as to funders and related stakeholders. CONCLUSIONS Rather than being a tool used at the end of an evaluation, we propose that integration is more usefully conceived as a process that commences at the start of an evaluation and continues throughout. To emphasize the importance of this timing, integration can be described as comprising 'Work Package Zero' within evaluations of complex PHIs.
