Psychological and lifestyle correlates of eating behavior and adiposity: Structural and latent profile modeling.
Article in PloS one, 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
backgroundPsychological vulnerabilities, including early maladaptive schemas (EMS) and difficulties in emotion regulation, are associated with dysregulated eating and adiposity. However, evidence integrating these mechanisms with contextual and lifestyle factors within a single framework remains limited. This study examined an integrative model of psychological and lifestyle correlates of eating behavior and adiposity in a large adult sample.
methodsA community sample of 1,500 adults (53% women; aged 18-65 years) completed validated measures of EMS, difficulties in emotion regulation, perceived stress, social support, eating behaviors, diet quality, and physical activity. Body mass index and waist circumference were assessed using standardized procedures. Structural equation modeling tested direct, indirect, and conditional associations, with multi-group analyses examining gender and age differences. Latent profile analysis identified subgroups with distinct psychological and lifestyle constellations.
resultsHigher EMS were associated with greater difficulties in emotion regulation. Emotion regulation difficulties were positively associated with emotional and habitual overeating (stronger among women) and showed a modest negative association with dietary restraint. Indirect effects of EMS via emotion regulation were small and limited to dietary restraint. Perceived stress did not moderate the EMS-emotion regulation association, whereas perceived social support showed a small buffering effect. Eating behaviors were associated with poorer diet quality related to higher body mass index and waist circumference, while physical activity and sedentary behavior showed independent associations with adiposity. Latent profile analysis supported a two-profile solution (higher- vs. lower-risk), characterized by distinct psychological, behavioral, and adiposity patterns.
conclusionsCognitive-emotional vulnerabilities are associated with eating dysregulation and adiposity, but emotion regulation plays a selective and modest mediating role limited to dietary restraint. Lifestyle behaviors contribute independently to adiposity alongside psychological pathways, supporting integrative, multidimensional models. Given the cross-sectional design, all findings are correlational and do not imply causality.
