Our hospital has been actively inducing delivery after 37 weeks of gestation in pregnant patients with glucose metabolism disorders under insulin treatment. Starting induction early （37-38 weeks of gestation） may lead to delivery via cesarean section, shoulder dystocia, and neonatal respiratory distress syndrome （RDS）.From 2011 to 2019, 35 pregnant women under insulin treatment were induced to deliver at 37 weeks of gestation in our hospital. Maternal background, labor outcomes, and neonatal outcomes were assessed.Cesarean section rates for early induction at 37, 38, and 39 weeks of were 7% （1/15 cases）, 38% （5/13 cases）, and 14%（ 1/7 cases）, respectively, but the difference was not significant（ p = 0.13）. Shoulder dystocia was found in 3 cases. Five newborns were admitted to the NICU : 3 with RDS, 1 with neonatal hypoglycemia, and 1 with low birth weight. The cesarean section rate for early induction was high only for a gestation age of 38 weeks, but these two variables had no significant relationship. In addition, the incidence of both shoulder dystocia and RDS were higher than previously reported. This may be because all the subjects in this study required insulin treat-ment.
