Eating disorders and eco-anxiety: exploring mental health challenges in university students.
Article in Journal of eating disorders, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
backgroundClimate change is a major global challenge with profound psychological impacts, including eco-anxiety, defined as a chronic fear of environmental catastrophe. Despite its potential role of exacerbating vulnerabilities to maladaptive coping mechanisms such as eating disorders (EDs), the relationship between eco-anxiety and eating disorders EDs remains underexplored, particularly in student populations. This study aimed to investigate the associations between eco-anxiety, EDs, and psychological variables among university students.
methodsA cross-sectional study was conducted among students, using an anonymous online questionnaire. Eco-anxiety was measured with the Hogg Eco-Anxiety Scale (HEAS-13), EDs were screened using the SCOFF questionnaire combined with body mass index to classify EDs into four categories: restrictive, hyperphagic, bulimic, and others. Additional measures included depression (CESD-8), insomnia severity (ISI), burnout (MBI-SS), and pro-environmental behaviors (PEBs). Multivariate analyses were used to identify determinants of EDs, and Multiple Correspondence Analysis (MCA) was conducted to explore relationships between categorical variables.
resultsA total of 1826 university students were included. Overall, 47.3% of the sample screened positive for a probable ED, with a higher prevalence among women (53.6%) compared to men (29.2%).; (p < 0.0001). Higher eco-anxiety quartile was associated with restrictive, hyperphagic, and bulimic EDs in multivariate model. By adding depression in the multivariate model, associations with restrictive and hyperphagic EDs diminished, suggesting a mediating role for depression. In contrast, eco-anxiety maintained a direct effect on bulimic EDs. The MCA revealed distinct clusters, with high eco-anxiety, insomnia, and depression closely linked to restrictive and hyperphagic EDs. Bulimic EDs were associated with intermediate levels of eco-anxiety and emotional exhaustion.
conclusionsThe study underscores eco-anxiety as an emerging risk factor for EDs, mediated in part by depression and other psychological factors. Differences in mechanisms across ED subtypes suggest that eco-anxiety contributes both directly and indirectly. This study enriches the knowledge by demonstrating how environmental stressors intersect with mental health and eating behaviors in vulnerable populations like university students. Public health initiatives should address eco-anxiety and its psychological sequelae to mitigate the risk of EDs, emphasizing tailored interventions based on ED subtype.
