The aim of the study was to evaluate the maternal and neonatal outcomes in women with recurrent gestational diabetes mellitus (GDM), compared to women with GDM.
This prospective observational cohort study was done on multiparous women with GDM attending the two tertiary care hospitals. Subjects were divided into two groups, recurrent GDM and GDM. Demographics, clinical variables, and maternal and neonatal outcomes were recorded between the two groups. The postpartum glycemic status was determined at six months.
There were 36 (20.2%) women with recurrent GDM and 142 (79.8%) women with GDM. Women with recurrent GDM were older (32.4 ± 6.2 versus 29.8 ± 5.6 years), had higher frequency of obesity, and insulin resistance than women with GDM. Women with recurrent GDM had poor glycemia at diagnosis as compared to GDM. Although the glycemic goals achieved were comparable but women with recurrent GDM have increased frequency of gestational hypertension, preeclampsia, and need for cesarean section. Women with recurrent GDM significantly had higher frequency of large for gestational age (LGA) and macrosomic neonates. Postpartum diabetes at six months was significantly higher in women with recurrent GDM.
Women with recurrent GDM are at increased risk of adverse maternal and perinatal outcomes despite achieving optimal glycemic goals and also at the most significant risk of postpartum diabetes.
