OBJECTIVE: We sought to compare the different mortality risks between delivery and expectant management in women with gestational diabetes mellitus (GDM). STUDY DESIGN: This is a retrospective cohort study that included singleton pregnancies of women diagnosed with GDM delivering at 36-42 weeks' gestational age in California from 1997 through 2006. A composite mortality rate was developed to estimate the risk of expectant management at each gestational age incorporating the stillbirth risk during the week of continuing pregnancy plus the infant mortality risk at the gestational age 1 week hence. RESULTS: In women with GDM, the risk of expectant management is lower than the risk of delivery at 36 weeks (17.4 vs 19.3/10,000), but at 39 weeks, the risk of expectant management exceeds that of delivery (relative risk, 1.8; 95% confidence interval, 1.2-2.6). CONCLUSION: In women with GDM, infant mortality rates at 39 weeks are lower than the overall mortality risk of expectant management for 1 week; absolute risks of stillbirth and infant death are low.
