Abstract
Purpose:
Evaluate associations of adolescents’ beverage marketing receptivity with sugar-sweetened beverage (SSB) perceived harm and intake.
Design:
School-based cross-sectional health behavior survey.
Setting:
Seven rural schools in California, 2019-2020.
Subjects:
815 student participants in grades 9 or 10.
Measures:
Participants viewed 6 beverage advertisement images with brand obscured, randomly selected from a larger pool. Ads for telecommunications products were an internal control. Receptivity was a composite of recognizing, liking, and identifying the displayed brand (later categorized: low, moderate, high). Weekly SSB servings were measured with a quantitative food frequency questionnaire and perceived SSB harm as 4 levels (“no harm” to “a lot”).
Analysis:
Outcomes SSB intake (binomial regression) and perceived harm (ordered logistic regression) were modeled according to advertisement receptivity (independent variable), with multiple imputation, school-level clustering, and adjustment for presumed confounders (gender, age, screen time, etc.).
Results:
In covariable-adjusted models, greater beverage advertisement receptivity independently predicted higher SSB intake (ratio of SSB servings, high vs. low receptivity: 1.48 [95% CI: 1.15, 1.89]) and lower perceived SSB harm (odds ratio, high vs. low receptivity: 0.59 [0.40, 0.88]). Perceived SSB harm was inversely associated with SSB intake.
Conclusion:
Beverage advertisement receptivity was associated with less perceived SSB harm and greater SSB consumption in this population. Policy strategies, including marketing restrictions or counter-marketing campaigns could potentially reduce SSB consumption and improve health.
