Abstract:
Objective To compare the difference of pregnancy outcomes between women who had a history of recurrent spontaneous abortion ( RSA) and women who were primigravida. Methods A case-control study was carried out. A total of 98 cases with a history of RSA and giving birth in the First Affiliated Hospital of Guangzhou University of Chinese Medicine from January of 2010 to September of 2014 served as the case group, while 98 primigravida giving birth at the same period in the same hospital were randomly selected as controls. The information collection form was designed following literature review before the research. All of the available data, including maternal demographic, reproductive information, medical history and present pregnancy outcomes, were collected from in-patient medical records. The number of valid information forms in case group was 91 and was 94 in control group after excluding the forms with incomplete data. The data was analyzed with SPSS 16.0 software. Results Univariate analysis results showed that maternal age, marital status, distribution of ABO blood groups, the history of infertility, clinical manifestation of threaten abortion, miscarriage treatment during pregnancy, medication of Zishen Yutai Pills for preventing miscarriage, time of delivery, adverse pregnancy outcome, and newborn sex were statistically significant different between the two groups ( P<0.05) . Logistic regression analysis results showed that there were significant differences in 5 factors between the two groups. Maternal age ( OR=1.466, 95%CI=1.267-1.698) , medication of Zishen Yutai Pills for preventing miscarriage ( OR=4.484, 95%CI=1.073-18.519) , and adverse pregnancy outcome ( OR=8.850, 95%CI=2.994-26.316) were the risk factors of RSA. Set blood type O as the classification reference, blood type A was a protective factor ( OR=0.259, 95%CI=0.088-0.765). And newborn sex was another protective factor of RSA ( OR=0.336, 95%CI=0.139-0.813). Conclusion Older women or women with blood type O are more likely to suffer from RSA than women with blood type A. Comparing with primigravida, women who had a history of RSA are more willing to accept medication of Zishen Yutai Pills for miscarriage, and women giving birth of a boy are more likely to have RSA and thereatened abortion, having high risk of adverse pregnancy outcomes particularly for the increase of gestational diabetes incidence.
