NCT01864564
First received: May 22, 2013

Last verified: December 2013
  Purpose

Specific Aim 1: To test the hypothesis that early GDM screening between 14-18 weeks in obese women (body mass index ≥30.0) will result in improved perinatal outcomes.

Specific Aim 2: To test the hypothesis that a lower diagnostic threshold for GDM at 14-18 weeks will result in improved detection of GDM and reduce the need for third-trimester testing.

Specific Aim 3: To test the hypothesis that 1,5-anhydroglucitol, a sensitive marker of hyperglycemia, can be used as a simple and sensitive serum test for GDM in the obese population.

Primary Outcome Measures:
  • Composite Perinatal Outcome [ Time Frame: Within 6 weeks of delivery ] [ Designated as safety issue: No ]
    Any one of the following: Macrosomia (birth weight > 4000 g), primary cesarean, gestational hypertension, preeclampsia, shoulder dystocia, neonatal hyperbilirubinemia, neonatal hypoglycemia (<40 mg/dL)


Secondary Outcome Measures:
  • Macrosomia [ Time Frame: Within 6 weeks of delivery ] [ Designated as safety issue: No ]
    Birth weight >4000 g

  • Primary cesarean delivery [ Time Frame: Delivery ] [ Designated as safety issue: No ]
    Primary cesarean : delivery via cesarean, first cesarean (does not include repeat cesarean deliveries)

  • Pregnancy induced hypertension [ Time Frame: Within 6 weeks of delivery ] [ Designated as safety issue: No ]
    Includes gestational hypertension and preeclampsia

  • Shoulder dystocia [ Time Frame: At birth ] [ Designated as safety issue: No ]
    Shoulder dystocia as identified by delivering physician

  • Neonatal hyperbilirubinemia [ Time Frame: Within 6 weeks of delivery ] [ Designated as safety issue: No ]
  • Neonatal hypoglycemia [ Time Frame: Within 6 weeks of delivery ] [ Designated as safety issue: No ]
    Blood sugar level <40 mg/dL

  • Preterm delivery [ Time Frame: Diagnosed at the time of delivery ] [ Designated as safety issue: No ]
    Delivery <37 weeks gestation

Arms Assigned Interventions
No Intervention: Routine Screening

Obese women will be screened at 24-28 weeks of gestation for gestational diabetes using the standard U.S. screening method of a 1-hour, 50-g glucose challenge test followed by a 3-hour, 100-g glucose tolerance test if abnormal. Women identified as having diabetes will be treated according to standards of care.

All women will have a hemoglobin A1c and 1,5-anhydroglucitol checked at 14-18 weeks and 24-28 weeks gestation.

Experimental: Early Screening

Obese women will be randomized to be screened at 14-18 weeks of gestation for gestational diabetes using the standard U.S. screening method of a 1-hour, 50-g glucose challenge test followed by a 3-hour, 100-g glucose tolerance test if abnormal. Women identified as having diabetes will be treated according to standards of care. Women who do not have diabetes at 14-18 weeks will be re-screened at 24-28 weeks per the standard of care.

All women will have a hemoglobin A1c and 1,5-anhydroglucitol checked at 14-18 weeks and 24-28 weeks gestation.

Other: Early Screen
Women will be randomized to be screened for gestational diabetes at 14-18 weeks gestation (early=intervention) versus routine screening at 24-28 weeks.
