Study on relationships between maternal anemia in third trimester and pregnancy outcomes

Objective To investigate the relationships between maternal anemia in the third trimester and pregnancy outcomes and serum iron of cord blood.Methods The 526 pregnant women,who participated in antenatal care in hospital from June 2006 to February 2007,were taken part in this study.The ambispective cohort study approach was used to collect the data prior to conception,antenatal care and pregnancy outcomes.Results The prevalence of pregnant women anemia in the third trimester was 42.95%,of which the prevalence of mild,moderate and severe anemia was 22.25%,19.60%,1.10%,respectively.The newborns' recumbent length,birth weight and gestational ages of moderate and severe anemia group were less than that of non-anemic group.Maternal hemoglobin in the third trimester was linearly correlated with newborns' recumbent length,birth weight and gestational ages.There was no linear correlation between maternal hemoglobin in the third trimester and newborns' serum iron of cord blood(r=-0.012,P0.05).Conclusion It is suggested that the anemia of pregnant women in the third trimester has adverse effects on pregnancy outcomes.There is no relationship between serum iron in cord blood and pregnant women anemia of the third trimester.
