Abstract: Objective To explore the effects of the two-child policy on the pregnancy characteristics and pregnancy outcome of elderly multiparturients.Methods We retrospectively analyzed maternal medical records of 950 pregnant women delivered in our hospital from January 2016 to June 2016. According to their number of births and ages, they were divided into primipara group 400 cases), multipara group (350 cases) and elderly multipara group (200 cases). Pregnancy outcomes and pregnancy complications of the three groups were observed. At the same time, the psychological status of the three groups of women at different time points was compared.Results The SDS and SAS scores at the different stages of pregnancy in the elderly multipara group were significantly higher than those in the primipara group (P<0.05). The incidence of adverse pregnancy outcomes in the elderly multipara group was significantly higher than that in primipara group, multipara group (P<0.05). The incidence of pregnancy complications in the elderly multipara group was significantly higher than that in the primipara and multipara groups (P<0.05).Conclusion Since the opening up of the two-child policy, the number of multiparas has increased significantly, the prevalence of pregnancy complications and adverse pregnancy outcomes was higher, and the maternal psychological comfort degree was lower.
