Newbury JB, et al. - Through a nationally representative Environmental-Risk Longitudinal Twin cohort study of 2,232 UK-born children, the contributors intended to examine the correlation among exposure to air pollution and adolescent psychotic experiences and test if the association between urban residency and adolescent psychotic experiences is mediated by it. Occurrence of confound by family socioeconomic status, family psychiatric history, maternal psychosis, childhood psychotic symptoms, adolescent smoking and substance dependence, or neighborhood socioeconomic status, crime, and social conditions weren't evident. Partial explanation of the association between urban residency and adolescent psychotic experiences was concluded via air pollution exposure—particularly nitrogen dioxide and nitrogen oxides, increasing the odds of adolescent psychotic experiences. Although, biological and psychosocial mechanisms were noticed as plausible.
