Nonlinear associations between maternal depressive symptoms and children's mental health: a cross-sectional study.
Article in BMC psychology, 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
backgroundWhile associations between maternal depressive symptoms (MDS) and offspring mental health have been documented, the precise nature of this relationship, particularly potential nonlinear patterns, remains insufficiently characterized.
objectiveThis study sought to examine potential nonlinear dose-response relationships between MDS and child mental health among preschool-aged children.
methodsWe conducted a cross-sectional investigation enrolling 17,115 mother-child dyads from kindergartens in a city in western China. MDS were assessed using the Center for Epidemiologic Studies Depression Scale (CES-D). Children's mental health was assessed via maternal reports using the Strengths and Difficulties Questionnaire (SDQ). Data were collected between February 28 and March 5, 2025.
resultsAmong the 17,115 mother-child dyads, 16.14% (n = 2,763) of mothers (mean age: 34.49 ± 4.65 years) reported elevated depressive symptoms (CES-D score ≥ 16). A nonlinear dose-response relationship was observed, with turning points at maternal CES-D scores of 17 for total difficulties and internalizing problems, 21 for externalizing problems, and 14 for prosocial behavior problems. Below these thresholds, stronger associations were observed (OR = 1.20 for total difficulties, OR = 1.16 for internalizing problems, OR = 1.10 for externalizing problems, and OR = 1.11 for prosocial behavior problems), while above the thresholds, the associations were substantially weakened.
conclusionThis cross-sectional study identified distinctive nonlinear dose-response associations between MDS and children's mental health outcomes in a western Chinese city. The associations were stronger below specific thresholds while weakening above these thresholds. These findings warrant further investigation and validation.
