Fluctuations in schizophrenic births by year

The British Journal of Psychiatry : the Journal of Mental Science
E F Torrey, R Rawlings

Abstract

It has previously been reported that births of individuals who later develop schizophrenia vary by birth year. Birth data were analysed on 34,024 individuals diagnosed with DSM-III-R disorganised, catatonic, and undifferentiated schizophrenia using time series analysis. Minor yearly fluctuations were observed but did not achieve statistical significance. Thus earlier findings reported in the literature could not be replicated using a different statistical approach. The findings do not support theories which assume major yearly fluctuations in the births of individuals with schizophrenia. Such theories include the perinatal effects of influenza, temperature variation, and the effects of severe weather.
