Abstract
APROSPECTIVE EPIDEMIOLOGIC study of spontaneous abortions and fetal wastage was done in Oklahoma City U.S.A. from September 1980 to September 1981 for the purpose of delineating the etiologic effects of previous abortions. 1050 pregnant women were followed from their first prenatal visit till the termination of pregnancy. In addition to the available information in the patients' medical records, a detailed questionnaire was administered to all the patients. Detailed information was sought on the patients' previous abortion history. A relationship was found between the history of previous spontaneous abortion and subsequent non-live birth, but not between induced abortion and non- live birth.
