College students' depression and body image: Unraveling the Link.
Article in World journal of psychiatry, 2025. 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
backgroundWith the increasing global incidence of mental illness, depression has become a serious problem among college students.
aimTo investigate the relationship between depression and its correlates in Chinese adolescents and to identify diagnostic predictors of depression, examine the effects of binge eating, physical activity, and body dissatisfaction on depression among college students and to determine a diagnostic cutoff value for depression based on body dissatisfaction.
methodsWe conducted a cross-sectional survey of 1286 college students in South China. Physical activity level, depressive symptoms, and binge eating behavior were assessed using the Physical Activity Scale-3, Zung Self-Rating Depression Scale, and Dutch Eating Behavior Questionnaire, respectively. The absolute difference between actual body mass index (BMI) and ideal BMI was used to indicate the level of body dissatisfaction. Structural equation modeling (SEM) and receiver operating characteristic (ROC) curve analysis were used to examine the relationships between these variables and depression.
resultsThe findings showed that female college students reported higher levels of depression. Physical activity, body dissatisfaction, and binge eating behavior were significantly associated with depression. SEM revealed that body dissatisfaction played a mediating role. A body dissatisfaction score of 1.73 was identified as the diagnostic cutoff value for predicting depression, with an area under the ROC curve of 70.0%, providing a basis for targeted interventions.
conclusionThis study demonstrated a significant positive correlation between body dissatisfaction and depression. Low levels of physical activity and binge eating behaviors were found to heighten the risk of depression. Therefore, promoting physical activity and healthy eating habits among adolescents is essential. Additionally, the identification of a diagnostic threshold for body dissatisfaction represents a novel finding with important implications for early screening. Future longitudinal studies are recommended to further refine this diagnostic criterion.
