N2 - The incidence of pre-eclampsia was studied in 9771 women that were pregnant for the first or second time. The protection offered by a previous pregnancy which ended in abortion was compared to that provided by a first pregnancy that proceeded to term. The rate of pre-eclampsia was 2.9% for primigravid women and was significantly lower (1.5%, p < 0.001) for women giving birth for the second time. Adjusting by multiple regression for confounding factors (e.g., maternal age, social class, ethnic origin and smoking), the incidence of pre-eclampsia was also significantly lower (p = 0.038) following an induced abortion, but not following a spontaneous abortion.
