The oral glucose tolerance test and short-term adverse outcomes among patients with gestational diabetes mellitus

Objective To investigate the relationship between oral glucose tolerance test (OGTT) findings and short-term adverse pregnancy outcomes among women with gestational diabetes mellitus. Methods We retrospectively collected 387 cases of pregnant womenwith gestational diabetes mellitus from 2020 to 2021 at the Maternity & Child Care Center of Dezhou and analyzed laboratory results. According to OGTT values, patients were divided into three groups, and pregnancy outcomes were analyzed; these included gestational weight gain, gestational hypertension, cesarean section, preterm birth, dead fetus, fetal distress, fetal growth restriction, congenital disabilities, macrosomia, and low birth weight. In group 1, 277 patients had abnormal OGTT values, and short-term adverse outcomes were studied. Results Three abnormal OGTT points were accompanied by significant gestational weight gain, gestational hypertension incidence, and low birth weight incidence; the risks of cesarean section and preterm birth increased. Abnormal fasting plasma glucose was associated with gestational hypertension. Conclusion OGTT findings can be used to alert clinicians to short-term adverse outcomes in mothers and infants. Clinicians should be aware of abnormal OGTT findings.
