Correlation Analysis of Pregnancy Outcomes and Blood Glucose Index at Different Time Points in 75 g OGTT / 实用妇产科杂志

ABSTRACT

Objective:To study the relationship between pregnancy outcomes and blood glucose index at different time points in 75 g oral glucose tolerance test (OGTT).Methods:A total of 403 pregnant women who receiveda 75 g OGTT were enrolled.Pregnant women were divided into three groupsgroup A with one abnormal blood glucose level (group A1abnormal fasting glucose level;group A2abnomal 1 hour glucose level;group A3abnormal 2 hour glucose level), group B with two abnormal blood glucose level (group B1abnormal fasting and 1 hour glucose level;group B2abnormal fasting and 2 hours glucose level;group B3abnormal 1 hour and 2 hours glucose level), and group C with abnormal blood glucose level in all three time points.Retrospective analysis of general information and pregnancy outcomes of pregnant women.Results:There were significant differences in A, B and C groups when comparing the incidence of hypothyroidism, hypertensive disorders of pregnancy, cesarean section rate, neonatal body mass index (BMI), chest circumference, macrosomia preterm birth and transfer to Neonatal Intensive Care Unit (P＜0.05), and the incidence of adverse outcomes in group C was higher than that in group A and B.The neonatal body mass index, chest circumference and fetal distress rate and cesarean section rate in the A2 group were significantly higher than those in the A1 and A3 groups (P＜0.05).The incidence of macrosomia and cesarean section in group B3 was lower than that in group B1 and B2 (P＜0.05).Conclusions:The maternal and neonatal adverse outcomes would increase if the abnormal glucose level was detected in all three time points in 75 g OGTT.When the fasting and 1 or 2 hour blood glucose level were abnormal, the incidence of neonatal macrosomia would increase.There could be a correlation between 1 hour blood glucose level and neonatal body mass index.
