Abstract

Purpose: Peer victimisation, often a serious childhood stressor, has been associated with poor cognitive outcomes. The current study sought to uncover whether peer victimisation is associated with poor cognitive functioning in childhood via inflammation.

Methods: Data from 4583 participants in the Avon Longitudinal Study of Parents and Children (ALSPAC) were analysed. Path analysis was conducted to determine whether inflammation, measured using IL-6 and CRP levels (age 9), mediates the effects of peer victimisation (age 8), even after controlling for other stressors, on multiple cognitive outcomes, including working memory (age 10), reading (accuracy, speed, and comprehension) (age 9), spelling (age 9), response inhibition (age 10), attentional control (age 11), and selective attention (age 11).

Results: IL-6 and CRP partially mediated the effects of peer victimisation on working memory, reading accuracy, and selective attention. IL-6 partially mediated the effect of peer victimisation on reading comprehension, while CRP partially mediated the effect of peer victimisation on reading speed. All effects were small. Inflammation did not mediate the effects of peer victimisation on spelling, response inhibition or attentional control.

Conclusion: Peer victimisation may impact on some aspects of children's cognitive functioning via inflammation. The cognitive outcome specificity observed warrants further research.

期刊介绍： Social Psychiatry and Psychiatric Epidemiology is intended to provide a medium for the prompt publication of scientific contributions concerned with all aspects of the epidemiology of psychiatric disorders - social, biological and genetic. In addition, the journal has a particular focus on the effects of social conditions upon behaviour and the relationship between psychiatric disorders and the social environment. Contributions may be of a clinical nature provided they relate to social issues, or they may deal with specialised investigations in the fields of social psychology, sociology, anthropology, epidemiology, health service research, health economies or public mental health. We will publish papers on cross-cultural and trans-cultural themes. We do not publish case studies or small case series. While we will publish studies of reliability and validity of new instruments of interest to our readership, we will not publish articles reporting on the performance of established instruments in translation. Both original work and review articles may be submitted.
