Reducing children’s exposure to unhealthy food marketing is crucial to combat childhood obesity. We aimed to estimate the reduction of children’s exposure to food marketing under different policy scenarios and assess exposure differences by socio-economic status. The results suggest that plain packaging would result in the greatest decrease in children’s exposure to food marketing. However, given that children are regularly exposed to unhealthy food marketing in multiple settings through a range of marketing mediums, comprehensive bans are needed to protect children’s health.
