Countries worldwide have committed to a zero increase in obesity by 2025. To meet this commitment, governments are encouraged to promote healthy behaviours and reshape obesogenic environments through a variety of population-wide policies.
Limiting children’s exposure to the marketing of unhealthy foods and beverages is one such measure. Currently, over 30 countries have some form of mandatory marketing restriction in place.
While other reviews investigated the effectiveness of marketing restrictions for preventing obesity, the current review assessed the cost and cost-effectiveness, equity and acceptability of interventions to limit child exposure to unhealthy foods marketing.
