Perinatal outcome in pregnancies complicated with gestational diabetes mellitus and very preterm birth: case-control...

Preterm birth is defined as all births before 37 completed weeks of gestation. Preterm birth can be further sub-divided based on gestational age: extremely preterm (<28 weeks), very preterm (28 to <32 weeks) and moderate preterm (32 to <37 weeks). Retrospective observational case-control study review (1 year i.e., 2015) is to assess pregnancy outcome among women with gestational diabetes mellitus (GDM) delivering very preterm (28 + 0/7 to 31 + 6/7 weeks of gestation). The study group included all women diagnosed with GDM and were compared to a control group of women delivering at the same gestational age period but without GDM. In all, 30 women were included in the study, of whom 15 were diagnosed with GDM and 15 were not. All women had a cesarean delivery. Neonates of mothers with GDM had higher ponderal index. Birth weight had the positive associations with blood glucose of newborn (r = 0.37, p = 0.047) and term of births (r = 0.52, p = 0.003). Birth weight had the negative associations with maternal systolic pressure (r = -0.7, p < 0.05), pre-eclampsia (r = -0.6, p < 0.05) and maternal pre-pregnancy body mass index (r = -0.5, p < 0.05). There were no differences in mortality or other parameters for neonatal morbidity, including bronchopulmonary dysplasia, prematurity retinopathy, neonatal anemia. According to our data, very preterm delivery occurring in women with GDM does not confer an increased risk for neonatal complications.
