The impact of junk food marketing regulations on food sales: an ecological study.
Obesity Reviews 2018 June
OBJECTIVE: To evaluate the impact of junk food broadcast marketing policies on nationwide junk food sales and identify policy characteristics effective in reducing sales.
METHODS: Country policy data (n = 79) were categorized in a thorough literature review and analysed using a repeated measures design against data on food sales per capita. Study conducted in United States, 2017.
RESULTS: Countries with junk food broadcast marketing policies saw a decrease in junk food sales per capita after implementation, while those without said policies saw an increase (p = 0.013). Countries with statutory policies saw a decrease in sales per capita, while those with only self-regulation saw an increase (p = 0.004). Audience restrictions (p = 0.024) and standardized nutrition criteria (p = 0.008) were policy characteristics significantly associated with a decrease in sales per capita.
CONCLUSIONS: Utilizing a novel approach to evaluate junk food broadcast marketing policies, the study demonstrated that countries with statutory policies saw a significant decrease in junk food sales per capita not seen in countries with no or only self-regulatory policies. To effectively reduce exposure to child-targeted junk food marketing, governments should establish strong, comprehensive statutory regulations. Additionally, countries that implement junk food marketing policies can use food sales data to track policy effectiveness.
