Item Perinatal Outcomes of Two Screening Strategies for Gestational Diabetes Mellitus: A Randomized Controlled Trial(Wolters Kluwer, 2021) Davis, Esa M.; Abebe, Kaleab Z.; Simhan, Hyagriv N.; Catalano, Patrick; Costacou, Tina; Comer, Diane; Orris, Steven; Ly, Kathleen; Decker, Alison; Mendez, Dara; Day, Nancy; Scifres, Christina M.; Obstetrics and Gynecology, School of MedicineObjective: To evaluate differences in short-term perinatal outcomes between the two prominent screening strategies for gestational diabetes mellitus, the International Association of Diabetes and Pregnancy Study Groups (IADPSG) and Carpenter-Coustan. Methods: In this single-site, blinded, randomized, comparative effectiveness trial, participants received a nonfasting 50-g oral glucose tolerance test and, if less than 200 mg/dL (less than 11.1 mmol/L), were randomized to further screening with either IADPSG or Carpenter-Coustan criteria. Gestational diabetes treatment occurred per routine clinical care. The primary outcome was incidence of large-for-gestational-age (LGA) neonates. Prespecified secondary outcomes included small-for-gestational-age (SGA) neonates, cesarean birth, and neonatal and maternal composites of adverse perinatal outcomes. Assuming a 15% incidence of LGA neonates in the Carpenter-Coustan group, 782 participants provided more than 80% power to detect a 7% absolute risk reduction with the use of IADPSG; planned recruitment was 920 for anticipated attrition. Results: From June 2015 to February 2019, 1,016 participants were enrolled and 921 were randomized to IADPSG (n=461) or Carpenter-Coustan (n=460) groups. Gestational diabetes incidence (14.4% vs 4.5%, P<.001) and diabetes medication use (9.3% vs 2.4%; P<.001) were more common in the IADPSG group; there were no differences in LGA neonates, either overall (risk reduction 0.90, 97.5% CI 0.53-1.52) or among women without gestational diabetes (risk reduction 0.85, 97.5% CI 0.49-1.48). Those screened with IADPSG had higher rates of neonatal morbidity but fewer study-related adverse events. Rates of SGA neonates, cesarean birth, and maternal morbidity composite did not differ significantly between study groups. Conclusions: The IADPSG screening criteria resulted in more women diagnosed and treated for gestational diabetes than Carpenter-Coustan without reducing the incidence of LGA birth weight or maternal or neonatal morbidity.Item Treatment of Gestational Diabetes Mellitus and Offspring Early Childhood Growth(Endocrine Society, 2021-04) Feghali, Maisa; Atlass, Jacqueline; Abebe, Kaleab Z.; Comer, Diane; Catov, Janet; Caritis, Steve; Arslanian, Silva; Scifres, Christina; Obstetrics and Gynecology, School of MedicineBackground: Gestational diabetes mellitus (GDM) is associated with fetal overgrowth, and certain treatments are associated with an increased risk of macrosomia. However, there are limited data about the long-term effect of GDM treatment on childhood growth. Methods: Cohort study of 816 women with GDM and their offspring delivered between 2009 and 2012. Childhood height and weight through age 3 were collected from the medical record and z-scores and body mass index (BMI) were calculated. We assessed the association between GDM treatment and childhood growth using linear mixed modeling. Results: Treatment was divided into medical nutritional therapy (MNT) (n = 293), glyburide (n = 421), and insulin (n = 102). At delivery, birthweight, z-score, and BMI were higher in the offspring of women treated with either glyburide or insulin compared to MNT. However, weight, z-score, and BMI were similar among all offspring at 6 months and 1, 2, and 3 years of age. After controlling for covariates, there were differences in the weight z-score (P = 0.01) over the 3-year period by treatment group, but no differences in weight (P = 0.06) or change in BMI (P = 0.28). Pairwise comparisons indicated that insulin was associated with more weight gain compared with MNT (0.69 kg; 95% CI, 0.10-1.28; P = 0.02) and glyburide was associated with a trend toward lower weight z-score compared with MNT (-0.24; 95% CI, -0.47 to 0.003; P = 0.05). Conclusion: Despite growth differences detected at birth, we observed no meaningful differences in childhood growth from 6 months to 3 years among treatment groups, including in the offspring of women with GDM treated with glyburide.
