Effectiveness of universal secondary school-based interventions addressing the psychological risk factors of eating disorders in adolescents: a systematic review.
Review in Journal of eating disorders, 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
objectiveTo evaluate the effectiveness of universal secondary-school interventions targeting core eating disorder (ED) psychopathology and at least one additional psychological risk factor.
methodA systematic search of databases was conducted, including Scopus, CINAHL, Embase, PsycINFO, MEDLINE and Google Scholar in March 2025. Eligible randomised controlled trials (RCTs) reported quantitative outcomes (e.g., ED psychopathology, body dissatisfaction, dieting behaviors) following universal secondary-school interventions addressing weight, shape, or eating concerns and another psychological risk factor in non-clinical adolescents aged 11-18. Results were synthesized narratively, and study quality was evaluated using the Cochrane Risk of Bias (RoB-2).
resultsSeventeen RCTs were included. Eleven studies were conducted in Europe, most participants were female and in middle adolescence. Overall, most universal school-based ED interventions produced some immediate improvement in ED symptoms or well-being but effects were generally small or rarely sustained at follow-up. There were no significant changes in BMI. However, the high risk of bias limits the confidence of findings. DISCUSSION: These improvements were short term, and their effects were mostly small. Future research would benefit from adopting active comparison groups and longer follow-ups. Whilst core ED psychopathology in addition to the risk factors of body image dissatisfaction, dieting, self-esteem, and social media appear consistent factors to include in universal interventions, further understanding of the most effective risk factors to target in this population is needed.
