INDUCED-ABORTION AS A RISK FACTOR FOR SUBSEQUENT FETAL LOSS

The relation between past induced abortions and subsequent fetal loss is still unclear. We report a case control study with 331 cases of fir st Spontaneous abortion and 993 controls with no previous spontaneous abortion and a normal pregnancy at the same period of pregnancy. In co mparison with primigravid women, the odds ratio for a fetal loss in th e current one was 1.41 [95% confidence interval (CI)=0.81-2.43] among women with one previous pregnancy ending in induced abortion, 4.43 (95 % CI=1.46-13.36) among those with two previous induced abortions out o f two pregnancies, and 1.35 (95% Cl=0.64-2.82) among women with three or more previous pregnancies ending in one or more induced abortions.
