Examining differences in children and adolescents' exposure to food and beverage marketing in Canada by sociodemographic characteristics: Findings from the International Food Policy Study Youth Survey, 2020

BackgroundMany countries, including Canada, are considering regulations to restrict food and beverage marketing to children. However, little evidence is available outside of the US on how marketing exposure differs across sociodemographic subgroups. ObjectiveTo investigate potential associations between child and adolescent sociodemographic characteristics and exposure to food and beverage marketing in Canada. MethodsParticipants (n = 3780) aged 10-17 self-reported exposure to food and beverage marketing across food categories, locations and marketing techniques. Logistic regression models tested relationships between sociodemographics (age, sex, ethnicity and income adequacy) and marketing exposure. ResultsAmong other differences identified, 13-17 years old were more likely than 10-12 years old to report seeing unhealthy food marketing online. Girls were more likely than boys to see such marketing online and in retail settings, while boys were more likely to see it in video games. Minority ethnicities (including Indigenous youth) and respondents with lower income adequacy generally reported more exposure than White and higher income respondents, respectively. ConclusionsThis study highlights important differences in marketing exposure among youth of different sociodemographic groups in Canada, including greater exposure to marketing among those most disadvantaged and emphasizes the essential need to consider food marketing across equity groups when developing restrictions on marketing to kids.
