Does outdoor advertising correlate with retail food purchases made by adolescents? A cross-sectional study in Canada.
Article in Health promotion international, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Food marketing plays a substantial role in shaping adolescent diets, having wide-ranging ramifications for health behaviours and outcomes throughout the life course. Yet, there remains a dearth of research about how outdoor advertising as a specific channel of food marketing affects purchasing behaviours. We examine self-reported purchases made at retail food outlets by adolescents as it relates to the availability of outdoor food and beverage advertising around each participant's home, school, and along the journey to and from school. We also consider the impacts of sociodemographics and consumption attitudes on purchasing, as compared to the geographic availability of outdoor advertising. Data are drawn from a survey completed by 545 adolescents in 2018 across four secondary schools in the Middlesex-London region of Ontario, Canada. The availability of outdoor advertising in the home and school environment is marginally correlated with self-reported purchases made at fast food, table-based, grocery, and variety retail outlets. However, consumption attitudes, cultural background, and gender are significantly correlated with purchases, with substantially larger effect sizes. The overall results were consistent between estimating the availability of outdoor advertising in the immediate area surrounding the home and along the journey to and from school. There is considerable health promotion policy interest in regulating outdoor advertising around child-serving locations. However, scarce health promotion resources would be better allocated to educational programming that addresses the substantial role of consumption attitudes in affecting adolescent purchasing behaviour, as compared to the considerably weaker impact of outdoor food advertising observed in our analysis.
