Sugar-Sweetened Beverage Demand and Tax Simulation for Federal Food Assistance Participants: A Case of Two New England States

Excessive consumption of sugar-sweetened beverages is a major concern in the efforts to improve diet and reduce obesity in USA, particularly among low-income populations. One of the most commonly proposed strategies to reduce sugar-sweetened beverage consumption is increasing beverage prices through taxation. The objective of this study was to evaluate whether and how price-based policies could reduce sugar-sweetened beverage consumption among participants in the federal Supplemental Nutrition Assistance Program. Using point-of-sale data from a regional supermarket chain (58 stores), we estimated the responsiveness of demand to sugar-sweetened beverage price changes among Supplemental Nutrition Assistance Program-participating families with young children. Own-price and cross-price elasticities for non-alcoholic beverages were estimated using a Quadratic Almost Ideal Demand System model. The study found evidence that a tax-induced sugar-sweetened beverage price increase would reduce total sugar-sweetened beverage purchases among Supplemental Nutrition Assistance Program participants, who were driven by purchase shifts away from taxed sodas and sports drinks to non-taxed beverages (bottled water, juice, milk). The substitution of non-taxed caloric beverages decreases the marginal effects of the sugar-sweetened beverage tax, yet the direct tax effects are large enough to reduce the overall caloric intake, with the average net reduction in monthly calories from sugar-sweetened beverages estimated at around 8% for a half-cent per ounce tax and 16% for a one cent per ounce tax. A beverage price increase in the form of an excise tax would reduce sugar-sweetened beverage consumption and increase healthier beverage purchases among low-income families.

The effect of sugar-sweetened beverage price increases and educational messages on beverage purchasing behavior among adults

There is a paucity of evidence regarding the impact of sugar sweetened beverage (SSB) price increases on beverage consumption, using individual-level data, for the population overall and for different socioeconomic groups. This study aimed to predict the impact of altered beverage prices and educational messages on consumer purchasing behavior. 2020 adults representative of the Australian population by age, gender and income completed a discrete choice experiment online in 2016. Each subject completed 20 choice scenarios in a hypothetical convenience store setting where subjects chose between seven SSB and non-SSB beverage options or a no beverage option. Beverage prices and volumes varied between scenarios. Half of participants (n = 1012) were randomly exposed to an educational poster discouraging SSB consumption prior to completing choice scenarios. We used discrete choice models to predict purchases under several policy proposals, overall and for income and SSB consumption frequency sub-groups. Compared to baseline prices, a 10% SSB price increase was predicted to reduce SSB purchases by 15.0% [95%CI -15.2, −14.7], and increase purchases of non-SSBs by +11.0% [95%CI 10.8, 11.2] and no beverage by +15.5% [95%CI 15.1, 15.9]. Effects were greater with a 20% SSB price increase. Across all policy scenarios, the highest income quintile had a similar absolute and slightly greater relative decrease in SSB purchases compared to the lowest quintile. Educational poster exposure reduced SSB choice for all groups, with a greater reduction in the lower compared to higher income group, and additively increased response to price changes. Our results support the use of population-wide SSB pricing and educational interventions to reduce demand across all income groups.

Retailer-Led Sugar-Sweetened Beverage Price Increase Reduces Purchases in a Hospital Convenience Store in Melbourne, Australia: A Mixed Methods Evaluation

BackgroundLimited evidence has been gathered on the real-world impact of sugar-sweetened beverage price changes on purchasing behavior over time or in community-retail settings. ObjectiveOur aim was to determine changes in beverage purchases, business outcomes, and customer and retailer satisfaction associated with a retailer-led sugar-sweetened beverage price increase in a convenience store. We hypothesized that purchases of less-healthy beverages would decrease compared to predicted sales. DesignA convergent parallel mixed methods design complemented sales data (122 weeks pre-intervention, 17 weeks during intervention) with stakeholder interviews and customer surveys. Participants/settingElectronic beverage sales data were collected from a convenience store in Melbourne, Australia (August through November 2015). Convenience store staff completed semi-structured interviews (n=4) and adult customers exiting the store completed surveys (n=352). InterventionBeverages were classified using a state government framework. Prices of “red” beverages (eg, nondiet soft drinks, energy drinks) increased by 20%. Prices of “amber” (eg, diet soft drinks, small pure fruit juices) and “green” beverages (eg, water) were unchanged. Main outcome measuresChanges in beverage volume, item sales, and revenue during the intervention were compared with predicted sales. Statistical analysesSales data were analyzed using time series segmented regression while controlling for pre-intervention trends, autocorrelation in sales data, and seasonal fluctuations. ResultsBeverage volume sales of red (−27.6%; 95% CI −32.2 to −23.0) and amber (−26.7%; 95% CI −39.3 to −16.0) decreased, and volume of green beverages increased (+26.9%; 95% CI +14.1 to +39.7) in the 17th intervention week compared with predicted sales. Store manager and staff considered the intervention business-neutral, despite a small reduction in beverage revenue. Fifteen percent of customers noticed the price difference and 61% supported the intervention. ConclusionsA 20% sugar-sweetened beverage price increase was associated with a reduction in their purchases and an increase in purchases of healthier alternatives. Community retail settings present a bottom-up approach to improving consumer beverage choices.

Reduction of cardiovascular disease inequalities in the USA through dietary policy

BackgroundThe burden of cardiovascular disease mortality remains large and unequal in the USA, and is mostly attributable to poor diet. Few data exist about the potential population level impact on inequalities of policies to improve diet such as the Supplemental Nutrition Assistance Program (SNAP). We aimed to estimate reductions in cardiovascular disease mortality and inequalities achievable in the US population up to 2030 through dietary policies. MethodsWe developed a US IMPACT (International Model for Policy Analysis of Agricultural Commodities and Trade) food policy model to estimate the number of deaths prevented or postponed (DPPs) achievable with four feasible scenarios that have been successfully implemented across the world: a national fruit and vegetables and sugar-sweetened beverage mass media campaign, fruit and vegetable price reductions of 10% universally and 30% to SNAP participants, and universal sugar-sweetened beverage price increase of 10%. We further modelled a combination of these policies. We stratified the US population by SNAP eligibility and participation. We estimated number of deaths using the incremental effect of each policy upon the target food groups. Then we estimated the effect upon cardiovascular disease mortality compared with existing baseline of continued trends. Probabilistic sensitivity analyses were conducted. FindingsA universal 10% price reduction of fruit and vegetables could prevent the most deaths—about 150 500 DPPs by 2030 (95% CI 137 800–160 500). This compares with approximately 23 000 DPPs (21 500–24 600) generated through a 1 year mass media campaign, or 21 400 DPPs (18 200–24 500) by a 10% price increase in sugar-sweetened beverages. A 30% price reduction in fruit and vegetables for SNAP participants could result in roughly 35 100 DPPs (31 800–37 700) and also achieve the biggest reduction in inequalities between SNAP participants and the ineligible population. The combined policy approach would save most lives (about 204 800 DPPs) while also reducing inequalities. InterpretationFiscal strategies targeting diet could contribute to reduce the unequal cardiovascular mortality burden in the USA. All four dietary policies would be effective, but a combination of the universal and targeted aspects of policies would be the most effective. Individually, a universal 10% reduction in the price of fruit and vegetables might save most lives, whereas a targeted, 30% price reduction for SNAP participants could reduce inequalities the most.

Young adults' responses to alternative messages describing a sugar-sweetened beverage price increase.

Many jurisdictions in the USA and globally are considering raising the prices of sugar-sweetened beverages (SSB) through taxes as a strategy to reduce their consumption. The objective of the present study was to identify whether the rationale provided for an SSB price increase affects young adults' behavioural intentions and attitudes towards SSB. Participants were randomly assigned to receive one of eight SSB price increase rationales. Intentions to purchase SSB and attitudes about the product and policy were measured. A forty-six-item cross-sectional Internet survey. Undergraduate students (n 494) at a large US Midwestern university. Rationale type was significantly associated with differences in participants' purchasing intentions for the full sample (F 7,485=2·53, P=0·014). Presenting the rationale for an SSB price increase as a user fee, an effort to reduce obesity, a strategy to offset health-care costs or to protect children led to lower SSB purchasing intentions compared with a message with no rationale. Rationale type was also significantly associated with differences in perceptions of soda companies (F 7,485=2·10, P=0·043); among low consumers of SSB, messages describing the price increase as a user fee or tax led to more negative perceptions of soda companies. The rationale attached to an SSB price increase could influence consumers. However, these message effects may depend on individuals' level of SSB consumption.

Price elasticity of the demand for sugar sweetened beverages and soft drinks in Mexico

A large and growing body of scientific evidence demonstrates that sugar drinks are harmful to health. Intake of sugar-sweetened beverages (SSB) is a risk factor for obesity and type 2 diabetes. Mexico has one of the largest per capita consumption of soft drinks worldwide and high rates of obesity and diabetes. Fiscal approaches such as taxation have been recommended as a public health policy to reduce SSB consumption. We estimated an almost ideal demand system with linear approximation for beverages and high-energy food by simultaneous equations and derived the own and cross price elasticities for soft drinks and for all SSB (soft drinks, fruit juices, fruit drinks, flavored water and energy drinks). Models were stratified by income quintile and marginality index at the municipality level. Price elasticity for soft drinks was −1.06 and −1.16 for SSB, i.e., a 10% price increase was associated with a decrease in quantity consumed of soft drinks by 10.6% and 11.6% for SSB. A price increase in soft drinks is associated with larger quantity consumed of water, milk, snacks and sugar and a decrease in the consumption of other SSB, candies and traditional snacks. The same was found for SSB except that an increase in price of SSB was associated with a decrease in snacks. Higher elasticities were found among households living in rural areas (for soft drinks), in more marginalized areas and with lower income. Implementation of a tax to soft drinks or to SSB could decrease consumption particularly among the poor. Substitutions and complementarities with other food and beverages should be evaluated to assess the potential impact on total calories consumed.
