Food security and eating disorder behaviors in the International Food Policy Study, 2018 to 2022.
Article in International journal of epidemiology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
backgroundA link has been established between food insecurity and eating disorder (ED) pathology, but most research on this topic has occurred in the USA. This study examined associations and potential moderators of associations between food security (FS) levels and ED behaviors cross-nationally.
methodsRepeated cross-sectional data representing 104 881 adults 18-100 years of age in Australia, Canada, Mexico, the UK, and the USA came from five waves (2018-22) of the International Food Policy Study. Participants completed the Household Food Security Survey Module and reported on past-3-month binge eating and self-induced vomiting to control weight. Associations between past-year household FS level and ED behaviors were examined with adjusted modified Poisson regression models. Interactions with potential moderators were also tested.
resultsMarginal, low, and very low FS were associated with elevated prevalence of both ED behaviors. Compared with households with high FS, binge eating was 1.34, 1.54, and 1.73 times as prevalent in households with marginal, low, and very low FS, respectively. Associations were stronger for self-induced vomiting; compared with households with high FS, self-induced vomiting was 2.40, 7.10, and 11.98 times as prevalent in households with marginal, low, and very low FS, respectively. Moderation results revealed meaningful differences by some factors. For example, associations were weaker in Mexico and stronger among ethnic minorities and participants with children.
conclusionResults support cross-sectional associations between FS and ED behaviors, with a particularly strong link for self-induced vomiting. Some heterogeneity in these associations was observed across country and sociodemographic factors.
