Prenatal exposure to air pollution and childhood internalizing problems: roles of shyness and anterior cingulate cortex activity.
Article in Journal of child psychology and psychiatry, and allied disciplines, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
backgroundPrenatal exposure to air pollution increases the risk for psychiatric disorders characterized by internalizing problems. In this study, we examined the roles of shyness and anterior cingulate cortex (ACC) activity in the association between prenatal exposure to polycyclic aromatic hydrocarbons (PAH) and children's internalizing problems at 7-9 years old.
methodsParticipants include 53 children (31 girls, 22 boys). Personal air monitoring was conducted over 48 continuous hours during the third trimester of pregnancy to measure 8 PAHs. Mothers reported children's shyness (Emotionality Activity Sociability Temperament Survey) at age 5 and internalizing problems (Child Behavior Checklist) at ages 7-9. ACC activity was measured by fMRI during the Simon Spatial Incompatibility task at ages 7-9.
resultsShyness mediated the association between prenatal PAH exposure and internalizing problems. Higher prenatal PAH exposure predicted increased shyness, which in turn predicted greater internalizing problems. Moreover, left ACC activity during the Simon task moderated the association between prenatal PAH exposure and internalizing problems. Prenatal PAH exposure predicted increased risk for internalizing problems only when children showed heightened left ACC activity during the resolution of cognitive conflict.
conclusionsOur study innovatively synthesizes the fields of developmental psychology and environmental health science to offer new insights into the risk factors for anxiety disorders. Facilitating the development of healthy reactive and regulatory processes may improve the developmental outcomes for children highly exposed to air pollution.
