1 · What the graph read from it

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.

Abstract

backgroundImproving adolescent diets requires promising interventions, best developed through participatory research like Citizen Science (CS). The present study aimed to assess the impact of a CS intervention on the consumption of healthy and unhealthy snacking choices for adolescents living in deprived areas and the influence of gender, age, and socioeconomic status (SES) in snacking behaviour.

methodsSEEDS is a cluster-randomised controlled trial (c-RCT) in four European countries, with 26 high schools randomized to intervention (IG) or control (CG) groups. The analysis included 1,208 adolescents aged 13–15 (IG = 589, CG = 619). Adolescents from IG in each country co-created a 6-month intervention on healthy snacking and physical activity. Snack consumption was the main outcome, assessed via the Health Behaviour in School-Aged Children questionnaire. General Linear Models analysed intervention impact and the influence of gender, sex, and SES.

resultsIG adolescents showed higher odds than CG of daily fruit consumption [OR (95% CI) = 1.44 (0.03–2.02)], daily water consumption [OR (95% CI) = 1.89 (1.30 -2.77)] during school, and daily vegetable consumption [OR (95% CI) = 1.36 (1.01–1.82)] outside school hours. IG adolescents showed a higher odds of occasional cake/biscuits consumption [OR (95 CI) = 1.55 (1.14–2.13); OR (95% CI) = 1.82 (1.39–2.39)] and occasional juices/smoothies’ consumption [OR (95 CI) = 1.57 (1.15–2.16); OR (95% CI) = 1.33 (1.03–1.71)] than CG during and outside school. No effects were found for other snacks.

conclusionsA CS intervention, co-created by adolescents, improved snacking in and out of school, though promoting healthy snacking remains challenging and should be a focus for future efforts.
