Study on Relationship between Blood Glucose Monitoring Frequency of the Pregnant Women with Gestational Diabetes Mellitus and Perinatal Outcomes

Objective To explore the relationship between blood glucose monitoring frequency of pregnant women with gestational diabetes mellitus(GDM) and perinatal outcomes.Methods 197 GDM pregnant women who took prenatal care at the Women' s Hospital School of Medicine,Zhejiang University,from Jan.2008 to Jan.2011 were recruited as research subjects.All recruited pregnant women were treated with diet therapy combined with physical exercise to control the level of blood glucose;insulin therapy was used if necessary.The pregnant women were divided into three groups,according to monitoring frequency of blood glucose.Group A including 40 cases were monitored four times every day,and group B(88 cases) were monitored four times every other day,while group C(69 cases) four times every week.The compliance of blood glucose monitoring and incidence of maternal complications were analyzed.Results Compliance of blood glucose monitoring in group B and C were significantly higher than those in group A(P 0.01).Incidence of preeclampsia,neonatal asphyxia,polyhydramnios,premature birth,neonatal hypoglycemia,fetal macrosomia and caesarean section in group C were significantly higher than those in group A and B.There was no significant difference for incidence of perinatal complications in group A and B(P 0.05).Conclusion The pregnant women,treated with diet therapy combined with physical exercise and monitor blood glucose levels every the other day,could reduce economy and mental stress as well as perinatal complications.Pregnant women with insulin therapy still need to control blood glucose every day in order to reduce the incidence of maternal and fetal complications.
