Food Insecurity Predicts Excessive Exercise, Dietary Restriction, Cognitive Restraint, and Purging, but Not Binge Eating, in College Students Across 3 Months.
Article in The International 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 4 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
objectivesCollege students are at elevated risk for both food insecurity and eating disorder (ED) symptoms. Prior literature supports cross-sectional associations between food insecurity and ED symptoms, including binge eating, purging (e.g., diuretic and laxative misuse, self-induced vomiting), and dietary restriction. However, less is known about the temporal relation, particularly among college students.
methodsWe tested associations between food insecurity and cognitive restraint, binge eating, dietary restriction, purging, and excessive exercise across one college semester (three months). College students [N = 259; mean (SD) age = 19.22 (1.23)] were recruited to complete the Eating Pathology Symptoms Inventory (EPSI) and the 30-day version of the United States Department of Agriculture Adult Food Security Survey Module in August (baseline) and November (follow-up). We conducted five multiple regression models to examine baseline food insecurity as a predictor of each EPSI subscale score of interest, adjusting for baseline EPSI score, sociodemographic characteristics, and body mass index.
resultsBaseline food insecurity significantly predicted greater cognitive restraint (β = 0.12, p < 0.05), dietary restriction (β = 0.18, p < 0.001), excessive exercise (β = 0.15, p < 0.01), and purging (β = 0.14, p < 0.05) at follow-up, adjusting for baseline levels, sociodemographic characteristics, and body mass index. Baseline food insecurity did not predict binge eating at follow-up when the baseline level, body mass index, and sociodemographic characteristics were considered. DISCUSSION: Experiencing food insecurity may contribute to the development or exacerbation of excessive exercise, dietary restriction, cognitive restraint, and purging among college students. Findings highlight the potential need for food insecurity interventions to include support for disordered eating.
