Maternal Psychological Distress Before and After Childbirth and Neurodevelopmental Delay in Toddlers.
Article in JAMA network open, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
Importance: Maternal psychological distress is a risk factor for neurodevelopmental delay in the offspring, but no previous studies have examined this while considering the bidirectional relationship between psychological distress and child development over time. Objective: To estimate the risk of neurodevelopmental delay in toddlers following maternal psychological distress during mid- to late pregnancy and at 1 year post partum. Design, Setting, and Participants: This birth cohort study, the Japan Environment and Children's Study (JECS), is an ongoing nationwide longitudinal cohort. Recruitment was conducted through 15 regional centers across Japan from January 2011 to March 2014. Participants were 82 418 mother-child pairs enrolled in the JECS. Data were analyzed from July 2024 to July 2025. Exposures: Psychological distress, defined as a Kessler Psychological Distress Scale (K6) score of 5 or greater. Main Outcomes and Measures: Neurodevelopmental delay, defined as a score less than the cutoff in any of 5 developmental areas identified at any of 4 measurement times (ages 1.5, 2.0, 2.5, and 3.0 years), using the Ages and Stages Questionnaire, Third Edition. A marginal structural modeling approach was used. Results: Among 82 418 mother-child pairs, the mothers' mean (SD) age was 31.1 (5.0) years, and 40 125 children (48.7%) were female. Compared with having no psychological distress at either time point, the adjusted odds ratio was higher when psychological distress was present at 1 year post partum only (aOR, 1.25; 95% CI, 1.18-1.33) than when it was present during mid- to late pregnancy only (aOR, 1.08; 95% CI, 1.03-1.13). The aOR for psychological distress at both time points was 1.38 (95% CI, 1.30-1.46). No salient multiplicative interaction between the 2 exposure periods was observed (aOR, 1.02; 95% CI, 0.93-1.11). Conclusions and Relevance: In this cohort study of 82 418 mother-child pairs, maternal psychological distress at 1 year post partum had an estimated higher risk of neurodevelopmental delay in toddlers than psychological distress during pregnancy. These findings suggest the importance of maintaining maternal mental health from pregnancy through 1 year post partum.
