Abstract

Background: Humans are inevitably exposed to multiple physical and social environmental risk factors, potentially contributing to psychiatric problems and cognitive deficits; however, the combined effects of prenatal air pollution and psychosocial environments on youth remain unclear. This longitudinal study aimed to examine how prenatal ozone exposure interacts with psychosocial environments at 9-10 years to affect adolescent limbic system development, cognition, and psychotic-like experiences (PLEs) at 11-13 years.

Methods: We analyzed data from 6,778 participants in the Adolescent Brain Cognitive Development (ABCD) Study® at two time points (baseline: 9-10 years and 2-year follow-up). Prenatal ozone exposure was calculated as a 9-month average of daily exposure estimates based on birth year and address. Social environmental factors included school environment and neighborhood safety at both time points. Structural MRI measures included bilateral amygdala and hippocampus volumes at both time points. Behavioral data consisted of cognition and PLEs scores at both time points. Moderation and moderated mediation models with cluster-robust standard errors were constructed to examine the effects, controlling for covariates.

Results: Children who were prenatally exposed to greater ozone and had a more unfavorable school environment exhibited a smaller increase in left hippocampal volume, leading to poorer cognition and more PLEs. Moreover, children who were prenatally exposed to greater ozone and lived in a more unsafe neighborhood had a larger increase in right amygdala volume.

Conclusions: This longitudinal study is the first to demonstrate the combined effects of prenatal ozone pollutant and adverse social environments in childhood on youth psychotic-like experiences and cognition, highlighting the limbic system as an important neural mechanism underlying the effects.

期刊介绍： The Journal of Child Psychology and Psychiatry (JCPP) is a highly regarded international publication that focuses on the fields of child and adolescent psychology and psychiatry. It is recognized for publishing top-tier, clinically relevant research across various disciplines related to these areas. JCPP has a broad global readership and covers a diverse range of topics, including: Epidemiology: Studies on the prevalence and distribution of mental health issues in children and adolescents. Diagnosis: Research on the identification and classification of childhood disorders. Treatments: Psychotherapeutic and psychopharmacological interventions for child and adolescent mental health. Behavior and Cognition: Studies on the behavioral and cognitive aspects of childhood disorders. Neuroscience and Neurobiology: Research on the neural and biological underpinnings of child mental health. Genetics: Genetic factors contributing to the development of childhood disorders. JCPP serves as a platform for integrating empirical research, clinical studies, and high-quality reviews from diverse perspectives, theoretical viewpoints, and disciplines. This interdisciplinary approach is a key feature of the journal, as it fosters a comprehensive understanding of child and adolescent mental health. The Journal of Child Psychology and Psychiatry is published 12 times a year and is affiliated with the Association for Child and Adolescent Mental Health (ACAMH), which supports the journal's mission to advance knowledge and practice in the field of child and adolescent mental health.
