妊娠糖尿病孕妇糖化血红蛋白对新生儿血糖水平的影响

目的 妊娠期糖尿病(GDM)孕妇耱化血红蛋白(HbA1c)水平和新生儿血糖水平的关系.方法 检测743例GDM孕妇HbA1c值,按照HbA1c水平分为3组,＜5.5％为G1组,5.5％～6.5％为G2组,＞6.5％为G3组,监测每组孕妇所生新生儿1、4、8h的血糖值,采用SPSS17.0软件对3组新生儿低血糖及阈值血糖发生率进行比较.结果 (1)1 h低血糖发生率在G1和G2组均高于G3组(P＜0.05).4、8h低血糖发生率G3组高于G1和G2组(P＜0.05).(2)G1及G2组低血糖发生率随着时间延长而下降(P＜0.05),G3组低血糖发生率随着时间延长无明显下降(P＞0.05).(3)1、4、8h阈值血糖的发生率在G3和G2组高于G1组(P＜0.05),G2组和G3组之间差异无明显统计学意义(P＞0.05).(4)G1组阚值血糖发生率随着时间延长而下降(P＜0.05),G2组阈值血糖发生率在生后4h内无明显下降(P＞0.05),G3组阈值血糖发生率随着时间延长无明显下降(P＞0.05).(5)母亲HbA1c水平与婴儿生后1h血糖水平呈负相关(r=-0.401,P＜0.05).结论 GDM孕妇新生儿的低血糖及阈值血耱发病风险随HbA1c水平增高而增加.

Glycosylated hemoglobin's influence of pregnant women with gestational diabetes mellitus on neonatal blood glucose

Objective to analyze the relation between glycosylated hemoglobin (HbA1c) of pregnant women with gestational diabetes mellitus (GDM) and neonatal blood glucose.Methods HbA1c values of 743 pregnant women with GDM are detected,and according to HbA1c level,they were divided into 3 groups,such as G1 (HbA1c＜5.5％),G2 (5.5％≤HbA1c≤6.5％) and G3 (HbA1c＞6.5％).Newborn babies' blood glucose values of the women in each group are monitored respectively in the 1st hour and at the 4th and 8th hour.Neonatal hypoglycemia and incidence of threshold blood glucose in the three groups are compared by SPSS 17.0 software.Results (1) The incidence of neonatal hypoglycemia in G1 and G2 are both higher than thatin G3 in the 1st hour (P＜0.05).The incidence of neonatal hypoglycemia in G3 is higher than that in G1 and G2 at the 4th and 8th hour (P＜0.05).(2) With time extending,the incidence of neonatal hypoglycemia declines in G1 and G2 (P＜0.05),but there is no obvious decline in G3 (P＞0.05).(3)The incidence of threshold blood glucose in G3 and G2 are higher than that in G1 in the 1st hour,and at the 4th,8th hour(P＜0.05),and there is no obvious statistical difference between G2 and G3 (P＞0.05).(4)With time extending,the incidence of threshold blood glucose declines in G1 (P＜0.05),but it doesn't decline in G3 evidently(P＞0.05).And there was no obvious decline in G2 in the 4 hours after babies were born(P＞0.05).(5)A mother's HbA1c level has a negative correlation with her baby's blood glucose in 1 hour after birth(r=-0.401,P＜0.05).Conclusion The higher HbA1c level of pregnant women with GDM increases,the higher risks of their neonatal hypoglycemia and threshold blood glucose are.
