Key clinical point: Risk for shoulder dystocia was higher among women with gestational diabetes who showed a slowly improving glycemic control trajectory, highlighting the need for interventions that help achieve glycemic targets early after the diagnosis of gestational diabetes.
Major finding: Compared with women showing rapid improvements to attain optimal glycemic control, the risk for shoulder dystocia was higher among women showing slow improvements to attain suboptimal glycemic control (adjusted relative risk [aRR] 1.41; 95% CI 1.12-1.78) and was lower among women with stably optimal glycemic control from diagnosis to delivery (aRR 0.75; 95% CI 0.61-0.92).
Study details: Findings are from a population-based longitudinal cohort study including 26,774 women with gestational diabetes who received prenatal care.
