Association of a Sweetened Beverage Tax With Soda Consumption in High School Students.

ABSTRACT:

Importance

Sweetened beverage taxes are one policy approach to reduce intake of added sugars. Soda is the leading source of added sugars in the US diet, but few studies have examined how such taxes influence sweetened beverage intake in youth.

Objective

To estimate the association between the Philadelphia, Pennsylvania, beverage tax and adolescent soda intake.

Design, setting, and participants

This economic evaluation of school district-level Youth Risk Behavior Surveillance System data from September 2013 to December 2019 compared weekly soda intake in high school students in Philadelphia, a city with a sweetened beverage tax, with that in 7 comparison cities without beverage taxes. Difference-in-differences regression modeling was used to estimate change in soda intake in Philadelphia compared with control cities. Secondary analyses compared 100% juice and milk intake to explore potential substitution associations. Subgroup analyses evaluated differences by race and ethnicity and weight status (obesity and overweight or obesity). Analyses were performed between August 20 and October 20, 2020. School districts that had weighted data and a survey question on weekly soda intake from 2013 to 2019 were included. The study included high school students, grades 9 to 12, in school districts participating in the Youth Risk Behavior Surveillance System from 2013 to 2019.

Exposures

Implementation of a sweetened beverage tax in Philadelphia, Pennsylvania, in January 2017.

Main outcomes and measures

Reported weekly servings of soda, 100% juice, and milk.

Results

A total of 86 928 participants (weighted mean [SD] age, 15.8 [1.3] years; 49% female) from 8 US cities (including Philadelphia) were included. Before the tax, adolescents in the 7 comparison cities had a mean intake of 4 servings of soda per week compared with 5.4 servings per week in Philadelphia. Philadelphia's tax was associated with a reduction of 0.81 servings of soda per week (95% CI, -1.48 to -0.14 servings; P = .02) 2 years after tax implementation. There was no significant difference in 100% juice or milk intake, although Philadelphia adolescents consumed more juice than those in nontaxed cities. In subgroup analyses, the tax was associated with a reduction of 1.13 servings per week in Hispanic/Latinx adolescents (95% CI, -2.04 to -0.23 servings; P = .01) and 1.2 servings per week in adolescents with obesity (95% CI, -2.33 to -0.13 servings; P = .03).

Conclusions and relevance

This economic evaluation found that a sweetened beverage tax was associated with a reduction in soda intake among adolescents, providing evidence that such taxes can improve dietary behaviors.

Project description:ImportanceThe relationship between a sweetened beverage tax and changes in the prices and purchases of beverages and high-sugar food is understudied in the long term and in small independent food retail stores where sugar-sweetened beverages are among the most commonly purchased items.ObjectiveTo examine whether a 1.5 cent-per-fluid-ounce excise tax on sugar- and artificially sweetened beverages Philadelphia, Pennsylvania, was associated with sustained changes in beverage prices and purchases, as well as calories purchased from beverages and high-sugar foods, over 2 years at small independent stores.Design, setting, and participantsThis cross-sectional study used a difference-in-differences approach to compare changes in beverage prices and purchases of beverages and high-sugar foods (candy, sweet snacks) at independent stores in Philadelphia and Baltimore, Maryland (a nontaxed control) before and 2 years after tax implementation, which occurred on January 1, 2017. Price comparisons were also made to independent stores in Philadelphia's neighboring counties.Main outcomes and measuresChanges in mean price (measured in cents per fluid ounce) of taxed and nontaxed beverages, mean fluid ounces purchased of taxed and nontaxed beverages, and mean total calories purchased from beverages and high-sugar foods.ResultsCompared with Baltimore independent stores, taxed beverage prices in Philadelphia increased 2.06 cents per fluid ounce (95% CI, 1.75 to 2.38 cents per fluid ounce; P < .001), with 137% of the tax passed through to prices 2 years after tax implementation, while nontaxed beverage prices had no statistically significant change. A total of 116 independent stores and 4738 customer purchases (1950 [41.2%] women; 4351 [91.8%] age 18 years or older; 1006 [21.2%] White customers, 3185 [67.2%] Black customers) at independent stores were assessed for price and purchase comparisons. Purchases of taxed beverages declined by 6.1 fl oz (95% CI, -9.9 to -2.4 fl oz; P < .001), corresponding to a 42% decline in Philadelphia compared with Baltimore; there were no significant changes in purchases of nontaxed beverages. Although there was no significant moderation by neighborhood income or customer education level, exploratory stratified analyses revealed that declines in taxed beverage purchases were larger among customers shopping in low-income neighborhoods (-7.1 fl oz; 95% CI, -13.0 to -1.1 fl oz; P = .001) and individuals with lower education levels (-6.9 fl oz; 95% CI, -12.5 to -1.3 fl oz; P = .001).Conclusions and relevanceThis cross-sectional study found that a tax on sweetened beverages was associated with increases in price and decreases in purchasing. Beverage excise taxes may be an effective policy to sustainably decrease purchases of sweetened drinks and calories from sugar in independent stores, with large reductions in lower-income areas and among customers with lower levels of education.
