Prevalence and correlates of US adult public opinion on restricting junk food advertising to children on social media

Objective: To describe US adults’ levels of support, neutrality and opposition to restricting junk food advertising to children on social media and explore associations with socio-demographic and health-related characteristics. Design: In 2020–2021, we used cross-sectional data from the National Cancer Institute’s 2020 Health Information National Trends Survey to estimate the prevalence of opinions towards advertising restrictions and correlates of neutrality and opposition using weighted multivariable logistic regression. Setting: United States. Participants: Adults aged 18+ years. Results: Among the analytic sample ( n 2852), 54 % of adults were neutral or opposed to junk food advertising restrictions on social media. The odds of being neutral or opposed were higher among Non-Hispanic Black adults ( v . non-Hispanic White; OR: 2·03 (95 % CI 1·26, 3·26)); those completing some college (OR: 1·68 (95 % CI 1·20, 2·34)) or high school or less (OR: 2·62 (95 % CI 1·74, 3·96)) ( v . those with a college degree); those who were overweight ( v . normal weight; OR: 1·42 (95 % CI: 1·05, 1·93)) and those reporting a moderate (OR: 1·45 (95 % CI 1·13, 1·88)) or conservative (OR: 1·71 (95 % CI 1·24, 2·35)) political viewpoint ( v . liberal). Having strong ( v . weaker) weight and diet-related cancer beliefs was associated with 53 % lower odds of being neutral or opposed to advertising restrictions (OR: 0·47 (95 % CI 0·36, 0·61)). Conclusions: The current study identified subgroups of US adults for whom targeted communication strategies may increase support for policies to improve children’s food environment
