Schizophrenics have been repeatedly found to experience more obstetric
complications (OCs) at birth. The meaning of such a finding is debate
d, and the aim of this study is to contribute to the understanding of
OCs' aetiological role in schizophrenia. We compared a group of schizo
phrenic patients with their siblings and controls, on the basis of obs
tetric files stemming from the same University Hospital Maternity Ward
. Schizophrenic patients had more frequent umbilical cord complication
s and atypical presentations, as well as higher scores on a scale meas
uring OCs linked to possible neonatal asphyxia.
