Abstract:Objective To analyze of pregnancy outcome of gestational diabetes mellitus (GDM) patients with increased fasting blood glucose level in 75 g oral glucose tolerance test OGTT. Methods A total of 450 cases of pregnant women with increased fasting blood glucose of GDM who were received standard prenatal examination and delivered in our hospital from January 2015 to January 2018 were selected, and grouped according to the results of fasting, 1 and 2 hours after taking the glucose in OGTT test, only fasting blood glucase increased to GDM group Ⅰ, the fasting combined with elevalted blood glucose at any other time point as the GDM group Ⅱ, all three time points were elevated as GDM group Ⅲ. A total of 450 healthy pregnant women who were examined at the same time were selected for a control group, the pregnancy outcomes of the two groups were compared. Spearman correlation was used to analyze the relationship between different phase blood glucose and neonatal weight. Results The incidences of premature delivery,large for gestational age (LGA), cesarean section, and hypertensive disorder complicating pregnancy in the study group were higher than those in the control group (P<0.05); there were significant differences in the comparison of LGA, insulin usage and cesarean section (P<0.05), that was the complications increased with the growing abnormal blood glucose levels. There were no differences in premature delivery and hypertensive discorders comlicating pregnancy in the three groups (P>0.05). The incidence of LGA in GDM group Ⅲwas higher than that of GDM group Ⅰ, and the difference was statistically significant (P<0.05). There was no significant difference compared with GDM group Ⅱ(P>0.05).Comparison of insulin usage rate, GDM group Ⅲwas higher than that of GDM groupⅠ, and the difference was statistically significant (P<0.05). Spearman correlation analysis result showed that fasting plasma glucose was positively correlated with neonatal weight (r=0.122, P<0.01), that neonatal weight was on the rise with the increase of fasting blood glucose. Conclusion The incidence of adverse pregnancy outcome is significantly increased in GDM patients with OGTT multipoint abnormal blood glucose. The fasting blood glucose level is important for the prediction of pregnancy outcome and neonatal weight. Clinical management should be individualized based on OGTT abnormalities status .
