Sugar-sweetened beverages as the new tobacco: examining a proposed tax policy through a Canadian social justice lens

Experiences and perspectives of sugar-sweetened beverage consumption among Indigenous adults living in Manitoba

Sugar-sweetened beverages (SSB) are a health policy target. Indigenous populations are among the highest consumers of SSB in Canada. However, the Truth and Reconciliation Commission calls on governments to recognize health disparities among Indigenous populations as a consequence of colonialism and governmental policies. The purpose of this analysis was to explore emergent perspectives of Indigenous adults on experiences and perspectives of SSB consumption. We conducted a community-based participatory study in partnership with three Indigenous-led organizations. From 2019 to 2022, we completed qualitative interviews with Indigenous adults living in Island Lake Anisininew First Nation, Flin Flon, and Winnipeg's North End, a neighbourhood with high concentration of Indigenous people. Interviews were audio-recorded, transcribed verbatim, and analyzed thematically. Seventy-four adults participated in interviews, including 46 women, 26 men, and two identifying as two-spirit. Many participants, across all three locations, repeatedly and consistently described SSB or sugar as an addiction, which formed the primary theme for this analysis: addictive-like consumption of SSB. Addictive-like SSB consumption included comparison to other addictive substances, loss of control, and physical symptoms resulting from SSB intake (both positive and adverse) or attempting to reduce SSB intake. We identified two other secondary themes, i) perceived drivers and contexts of SSB consumption, and ii) health outcomes as a motivator for change. Perceived drivers or contexts included consuming SSB as a means to cope with stress, boredom, and poverty; SSB intake as being intertwined with other addictions or addictive substances; and drinking alone. In conclusion, addictive-like SSB consumption was reported by Indigenous adults. To address SSB intake among Indigenous populations, trauma-informed approaches should be explored that consider the colonial context.

"Coke's not a food": A critical discourse analysis of sugar-sweetened beverage tax acceptability by white residents from an upper-middle class neighborhood in Winnipeg Manitoba

Increasing concerns about the health impacts of sugar consumption has led to the proposition of a sugar-sweetened beverage (SSB) tax in Canada. However, competing concerns related to stigma and equity remain and have not been explored in a Canadian context. As part of a broader study examining the perspectives of various populations on SSB tax acceptability, we examined how residents of an upper-middle class neighborhood conceptualize SSB tax acceptability, and we explored the discourses that inform their discussion. We conducted and analyzed qualitative, semi-structured interviews with residents of an upper-middle class neighborhood in Winnipeg, Manitoba, Canada. Recruitment criteria were residence, adults, and English speaking. Critical discourse analysis methodology was used, and healthism (health moralism) and tax psychology informed the analysis. Eighteen participants volunteered: 15 females and 3 males; all self-identified as white, and all spoke about (grand)parenting. Healthist discourse was utilized in supportive discussion of SSB taxation. With the mobilization of healthism, ideal citizens and parents were described as "health conscious" and those who might be likely to reduce SSB intake because of taxation. Healthism also contributed to their identification of beverages targeted by a tax, versus those they deemed as having redeeming nutritional qualities. Limits to SSB tax support were expressed as fairness concerns, with a focus on the procedural justice of the tax. Participants supported SSB taxation and the discourses they employed suggested support for the tax was perceived as contributing to their construction of the kind of ideal, health-valuing citizens they hoped to embody. However, participants were also concerned about the fairness of implementation, although this did not outweigh the prioritization of good health.

The equitable impact of sugary drink taxation structures on sugary drink consumption among Canadians: a modelling study using the 2015 Canadian Community Health Survey-Nutrition

OBJECTIVE

Estimate the impact of 20 % flat-rate and tiered sugary drink tax structures on the consumption of sugary drinks, sugar-sweetened beverages and 100 % juice by age, sex and socio-economic position.

DESIGN

We modelled the impact of price changes - for each tax structure - on the demand for sugary drinks by applying own- and cross-price elasticities to self-report sugary drink consumption measured using single-day 24-h dietary recalls from the cross-sectional, nationally representative 2015 Canadian Community Health Survey-Nutrition. For both 20 % flat-rate and tiered sugary drink tax scenarios, we used linear regression to estimate differences in mean energy intake and proportion of energy intake from sugary drinks by age, sex, education, food security and income.

SETTING

Canada.

PARTICIPANTS

19 742 respondents aged 2 and over.

RESULTS

In the 20 % flat-rate scenario, we estimated mean energy intake and proportion of daily energy intake from sugary drinks on a given day would be reduced by 29 kcal/d (95 % UI: 18, 41) and 1·3 % (95 % UI: 0·8, 1·8), respectively. Similarly, in the tiered tax scenario, additional small, but meaningful reductions were estimated in mean energy intake (40 kcal/d, 95 % UI: 24, 55) and proportion of daily energy intake (1·8 %, 95 % UI: 1·1, 2·5). Both tax structures reduced, but did not eliminate, inequities in mean energy intake from sugary drinks despite larger consumption reductions in children/adolescents, males and individuals with lower education, food security and income.

CONCLUSIONS

Sugary drink taxation, including the additional benefit of taxing 100 % juice, could reduce overall and inequities in mean energy intake from sugary drinks in Canada.

Intake of Fruits, Vegetables, and Sugar-Sweetened Beverages among a Sample of Children in Rural Northern Ontario, Canada

There is evidence to suggest that dietary intake of children differs by rural/urban place of residence: rural children may have a higher intake of foods high in fat and sugar than those living in urban environments. The aim of this study was to examine the intake of fruits and vegetables (FV) and the frequency of sugar-sweetened beverage (SSB) consumption, among a sample of rural children in Northern Ontario, Canada, in two different seasons. Sociodemographic factors and children's FV and SSB intake were measured using two repeated cross-sectional surveys, and seasonal information was based on the month of data collection. Logistic regressions were used to examine the odds of children eating five or more FVs, and the odds of 'frequently or always' consuming SSBs. During the fall, children reported eating five or more FV more often, when compared to winter (53.9% vs. 48.3%). In the fall, 25.8% of children reported 'frequently or always' drinking SSB, compared with 16.9% in winter. Indigenous children were less likely to eat five or more FV (OR 0.34 (95% CI 0.12-0.95)) in the fall when compared to non-Indigenous children. Findings indicate that intake of FV among rural students in this region is low, and the frequency of SSB is high, when compared with national recommendations.

The health and financial impacts of a sugary drink tax across different income groups in Canada

BACKGROUND

Overconsumption of sugar-sweetened beverages (SSBs) contributes to childhood and adult obesity and numerous related diseases, including heart disease, strokes, cancers, and type 2 diabetes. It also increases healthcare costs. Sugary drink taxes have been implemented in several countries to curb sugar intake. However, there is a concern that sugary drink taxes are regressive. This study assessed the health and financial impacts of a simulated sugary drink tax across different income groups in Canada.

METHODS

A proportional multi-state life table-based Markov model simulated the 2016 Canadian population by income quintile. The model applied a 20 % tax on sugary drinks and determined the effects on type 2 diabetes and BMI-related diseases compared to no intervention. The income-specific parameters modelled included: population demographics; cross- and own-price elasticities; mean BMI; sugary drink consumption; mortality; and disease epidemiology.

RESULTS

A 20 % sugary drink tax was estimated to reduce the consumption of sugary drinks by an average of around 15 %, with a greater reduction in the lowest income quintile. The estimated mean reduction in BMI ranged from 0.21 to 0.33, dependent upon sex and income quintile; these reductions were greater among the lower income quintiles for both females and males. The 20 % sugary drink tax was estimated to avert approximately 690,000 DALYs over a lifetime among the 2016 Canadian adult population; estimated DALYs averted were approximately 156,000, 140,000, 137,000, 134,000, and 125,000 for the lowest through to the highest income quintile, respectively. Lifetime health care savings were estimated to be $2.27bn, $2.16bn, $2.17bn, $2.12bn, and $1.98bn for the lowest through to the highest income quintile, respectively. The estimated annual tax burden for the 2016 Canadian population was $1.4bn. The average absolute tax burden was estimated to be $39.00 to $44.30 per person, with the middle-income quintile bearing the heaviest absolute tax burden. The lowest income quintile would pay the highest proportion of income in tax, implying that the tax is regressive.

CONCLUSIONS

Low-income Canadians would gain the most health benefit from a sugary drinks tax. However, the lowest income quintile would also pay the largest proportion of income in tax. A tax on sugary drinks is therefore financially regressive but forecast to reduce health disparities across Canada.
