7.2
Researchers in two Swedish counties pilot-tested a child-centered smartphone app plus web dashboard in 2026 to map outdoor food-advertising exposure and identify hotspots. From 1,308 child-uploaded and 2,955 researcher photographs covering 34 hotspot areas, 77.5% of ads promoted ultraprocessed foods (UPFs); fruits/vegetables/seafood appeared in 20.8% and price promotions featured in 23.6%. Findings show pervasive UPF marketing across cities and SES, indicating need for policy action.
Scoring Rationale
Practical peer-reviewed pilot provides actionable mapping evidence; limited geographic scope and pilot design constrain broader generalizability.
