Many factors have been associated with the development of schizophrenia, yet few studies have looked at these same factors in individuals considered at risk for schizophrenia, but who have not yet reached diagnostic threshold. The rate of obstetrical complications was assessed as part of a comprehensive battery in subjects at risk (N=52), or in the first episode of schizophrenia (N=18), and in normal comparison subjects (N=43). The rate of obstetrical complications was increased in the at risk (46%) and first episode (39%) samples compared to the normal comparison (19%) group, however, follow-up analyses were only significant between the at risk and normal comparison subjects. Obstetrical complications may be an important risk factor in identifying vulnerable subjects and ultimately may, along with other risk factors, be part of an algorithm for determining likelihood of developing schizophrenia.
