Abstract

Background: Urbanicity, immigration and winter-birth are stable epidemiological risk factors for schizophrenia, but their relationship to schizotypy is unknown. This is a first examination of the association of these epidemiological risk factors with positive schizotypy, in non-clinical adolescents, controlling for a range of potential and known confounders. Methods: We collected socio-demographics, lifestyle, family and school circumstances, positive schizotypy dimensions and other personality traits from 445 high school pupils (192 males, 158 immigrants) from 9 municipalities in Athens and Heraklion, Greece, which covered a range of host population and migrant densities. Using multivariate hierarchical linear regressions models, we estimated the association of schizotypy dimensions with 1) demographics of a priori interest (winter-birth, immigrant status, urban characteristics), including family financial and mental health status 2) factors resulting from Principal Component Analysis (PCA) of the demographic and personal data and 3) factors resulting from PCA of the personality questionnaires. Results: Females scored higher on schizotypy than males. High Anxiety/Neuroticism was the most consistent and significant predictor of all schizotypy dimensions in both genders. In the fully adjusted models, urbanicity predicted magical thinking and unusual experiences in females, while winter-birth and immigration predicted paranoid ideation and unusual experiences respectively in males. Conclusions: These results support the continuum hypothesis and offer potential insights in the nature of risk conferred by winter-birth, urbanicity and immigration and the nature of important gender differences. Controlling for a wide range of potential confounding factors increases the robustness of these results and confidence that these were not spurious associations.
