Brief Summary:
This will be a randomization of two groups of obese pregnant women into early screening for diabetes mellitus at the time of their first or subsequent prenatal visits before 20 weeks of gestation versus standard time of screening for diabetes at 24 - 28 weeks as it is done for all pregnant women. The perinatal outcomes between the two groups will be compared to determine whether early screening for diabetes in all obese pregnant women has a clinical merit or significant.

Arm Intervention/treatment
Active Comparator: Screening for diabetes with 1-hour GCT and HbA1
Participants in this group will do 1-hour GCT before 20 weeks of gestation. Those with positive test will undergo 3-hours OGTT. Diabetes will be diagnosed if they have two or more abnormal values out of the 4 values and they will be treated accordingly based on the institutional protocol. They will also have HbA1C done.
Drug: Screening for diabetes with 1-hour GCT and HbA1
They will receive 50gm oral glucose tolerance test before 20 weeks and if abnormal, they will do the diagnostic test with 100gm OGTT with HbA1C.
Other Name: Early screening with only HbA1C

Experimental: Early screening with only HbA1C
Participants in this group will only have HbA1C done before 20 weeks but will do the standard diabetes screening at 24 - 28 weeks. Those who have abnormal values will also be treated based on the institutional protocol.
Drug: Screening for diabetes with 1-hour GCT and HbA1
They will receive 50gm oral glucose tolerance test before 20 weeks and if abnormal, they will do the diagnostic test with 100gm OGTT with HbA1C.
Other Name: Early screening with only HbA1C




Primary Outcome Measures :
  1. Large for gestational age or macrosomia [ Time Frame: To be assessed within 2 days after delivery. ]
    Birth weight of newborn more than 90 percentile or birth weight of 4000gm or more will be assessed at the completion of that pregnancy.


Secondary Outcome Measures :
  1. Maternal medical complications [ Time Frame: For 6 months during antepartum and 6 weeks postpartum. ]
    Development of preeclampsia

  2. Birth injuries [ Time Frame: To be assessed within 2 days of delivery. ]
    Third or 4th degree perineal lacerations will be assessed soon after successful vaginal delivery either spontaneous or with assisted vaginal delivery.

  3. Mode of delivery [ Time Frame: To be assessed within 2 days of delivery. ]
    Normal vaginal delivery, operative vaginal delivery or cesarean section

  4. Glycemic control [ Time Frame: To be assessed during pregnancy and 6 weeks postpartum. ]
    Use of HbA1C, and postpartum glucose challenge test as postpartum visit.
