National studies in Scandinavia and in England and Wales have shown that
schizophrenic patients are born significantly more often in the early
months of the year than would be expected from comparison with the general
population. The author examines additional evidence from England and Wales
and discusses possible sources of technical error. Although there is
currently no evidence of a causal association between season of birth and
schizophrenia, he suggests that this possibility should be given
consideration.
