目的:探讨妊娠期糖尿病(GDM)筛查的适宜方法和临床意义。方法:对所有首次产检孕妇进行GDM发病风险评估;对孕周在24～28周的孕妇以及首次产检超过28周的高危孕妇在孕32～34周口服50 g葡萄糖筛查,血糖≥7.8 mmol/L者进行OGTT检测。结果:GCT阳性率为18.43%,GDM发病率为1.23%,高风险孕妇GCT筛查阳性率、GDM、GIGT发生率均明显高于低风险孕妇,孕24～28周孕妇OGTT结果比28周以上的孕妇要敏感。结论:应重视妊娠期糖尿病的早期诊断,特别是合并妊娠期糖尿病高危因素的孕妇;推荐在孕24～28周期间进行GDM初步筛查。
Objective: To investigate the appropriate method and clinical significance of screening gestational diabetes mellitus (GDM). Methods: The risk of GDM was evaluated in all the first pregnant women. The pregnant women with gestational age from 24 to 28 weeks and the high-risk pregnant women who were born for the first time more than 28 weeks were enrolled in this study. 50g of glucose was orally taken at 32 to 34 weeks of gestation, L who OGTT test. Results: The positive rate of GCT was 18.43% and the incidence of GDM was 1.23%. The positive rate of GCT screening, the incidence of GDM and GIGT in high risk pregnant women were significantly higher than those of low risk pregnant women. The pregnant women with OGTT more than 28 weeks pregnant gestational age from 24 to 28 weeks Pregnant women to be sensitive. Conclusion: Early diagnosis of gestational diabetes should be emphasized, especially pregnant women with high risk of gestational diabetes mellitus. A preliminary screening of GDM is recommended during 24-28 weeks’ gestation.
