Objective To explore the correlation between adverse pregnancy outcomes and previous bearing status.
Methods The related information of pregnant and postnatal women was extracted from 6825 hospitalized records in two general hospitals and one special hospital, which were selected by the method of cluster sampling, and the related rate and correlation analyses were calculated.
Results Women who had abortion history were much easier to cause adverse pregnancy outcomes compared to those who had no abortion history, with the incidence rates of 16.83% and 13.31%, respectively; the incidence rates of adverse pregnancy outcomes of women who ever had zero, one, and two or more than twice of delivery were 14.14%, 16.34% and 22.78%, respectively; the rates of women on their third or more than third, second, first or zero pregnancy were 49.14%, 18.05%, 14.22% and 12.88%, respectively; and the rates of adverse pregnancy outcomes of women with abnormal and normal gestation history were 31.06% and 14.21%, respectively.
Conclusion The previous abortion, delivery times and abnormal gestation history are highly related to adverse pregnancy outcomes. Therefore, in order to reduce adverse pregnancy outcomes, it is necessary to make an effective family planning and decrease abortion and pregnancy.
