Differential trajectories of depression symptoms during pregnancy and prospective associations with postpartum eating disorder symptoms and cardiovascular health behaviors.
Article in Archives of women's mental health, 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
purposeApproximately one-in-ten individuals experience depression during pregnancy, a period marked by considerable biopsychosocial change. Prior research has investigated perinatal depressive symptom change and identified links to negative health outcomes, such as hypertension and delivery complications. However, it is unknown if these findings extend to pregnant people with higher weight, who may have increased risk. Additionally, understanding how depression experiences during pregnancy impact postpartum eating disorder (ED) symptoms and cardiovascular health behaviors can provide insight into prospective health consequences.
methodsParticipants (N = 257 individuals with pre-pregnancy BMI ≥ 25) completed assessments of depression, ED symptoms, and cardiovascular health behaviors at six timepoints across pregnancy and at six-months postpartum. In this secondary analysis, growth mixture modeling identified differential depressive symptom trajectories; ANOVA and Chi-square tests examined differences in postpartum ED symptoms, diet quality, physical activity, and sleep across trajectory groups.
resultsFour prenatal depressive symptom trajectory groups were identified: low depression (64.3%), moderate depression (19.2%), high, decreasing depression (8.6%), and stable, high depression (7.8%). Trajectory groups comprising individuals with higher prenatal depressive symptoms (stable and decreasing) had higher postpartum eating, shape, and weight concerns, more frequent loss of control eating, and worse sleep quality, relative to moderate- and low-symptom groups. Restraint, diet quality, and physical activity did not differ across groups.
conclusionsPrenatal depressive symptom trajectories may differentially relate to risk for postpartum ED symptoms and sleep behaviors among higher weight pregnant people. Future research should continue investigating perinatal depression, ED symptoms, and associated health behaviors to optimize screening and intervention in maternal healthcare.
