Evading regulation: young people's exposure to harmful commodity marketing in the social media feeds of their favourite influencers.
Article in Health promotion international, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Increasingly companies use social media influencers to market unhealthy products to young people, although we know little about the influencers young people follow and the content influencers post. This study aimed to identify influencers young people follow, examine their exposure to harmful commodity content in influencer accounts, and examine the Instagram accounts of the most popular influencers for harmful commodity content and marketing. In Stage 1, 807 young people (aged 16-20 years, M = 17.1; 58% female, 33% male, 6% gender diverse, 3% did not say) completed a survey on social media use; recalled their exposure to alcohol, tobacco, and vape content and marketing within posts of influencers they follow; and named three favourite influencers. Among respondents who followed influencers (n = 665; 82.4%), 56% reported seeing influencer posts containing vapes (n = 347/620) and 23% vape marketing (n = 137/604); 47% reported seeing posts containing tobacco (n = 291/616) and 13% tobacco marketing (n = 78/604); and 76% reported seeing posts containing alcohol (n = 472/622) and 43% alcohol marketing (n = 260/602). Under-age respondents (16-17 years) reported seeing more tobacco marketing than older respondents (18-20 years). In Stage 2, researchers collected all Instagram posts of the 18 most frequently named influencers for 2 months and ephemeral 'stories' for 2 weeks. These posts/stories were analysed for harmful commodity content and marketing. Twelve influencers posted content with harmful commodities, primarily alcohol (117 posts, 6% of posts) but also vape and tobacco products (14 posts, 1% of posts). We need platform transparency and stronger policy to protect young people from harmful commodity marketing within influencers' accounts.
