IMPACT OF CHILDBIRTH ON A SERIES OF SCHIZOPHRENIC MOTHERS - A COMMENTON THE POSSIBLE INFLUENCE OF ESTROGEN ON SCHIZOPHRENIA

From a series of 180 admissions to a Mother-Baby Unit 45 patients with diagnoses of schizophrenia were identified. Demographic data together with clinical information were noted, and each file was rated using t he OPCRIT programme. Two mutually exclusive groups were derived from O PCRIT, a 'narrow group' (n = 16), corresponding to subjects satisfying Feighner's criteria for schizophrenia, and a 'broad group' (n = 21), corresponding to those meeting ICD10 but not Feighner criteria. In add ition to significant differences in age on admission, employment, home circumstances, ethnicity and age of onset of illness, there was a mar ked contrast between broad and narrow groups in course of illness post partum. 43% of the broad group experienced an acute illness episode a fter delivery compared with none of the narrow group, a contrast not a ttributable to differences in clinical state or treatment during pregn ancy. These data suggests that childbirth may exert a differential eff ect on the course of illness in severe and more benign forms of schizo phrenia, and that more severe schizophrenic illnesses may not be influ enced by the changes associated with childbirth, such as the fall in o estrogen levels.
