title: Is a value of over 200 mg/dL in the oral glucose tolerance test, a marker of severity in patients with gestational diabetes mellitus?
abstract: OBJECTIVE
  To determine whether blood glucose values of over 200 mg/dL in the oral glucose tolerance test (OGTT) are associated with pregnancy complications and adverse perinatal outcomes in patients with gestational diabetes mellitus (GDM).
  
  
  METHODS
  A retrospective cohort study was performed comparing patients with GDM A1 (diet controlled) that had at least one value of 200 mg/dL or higher in the OGTT, to those who did not. Patients were treated at the diabetes day care clinic of a tertiary medical center between the years 1999 and 2010. Data were available from the computerized perinatal databases.
  
  
  RESULTS
  During the study period, 778 women with GDM were treated at the diabetes day care clinic. Of these, 162 had at least one test value of 200 mg/dL or greater. No significant differences regarding maternal and perinatal complications, such as polyhydramnios, macrosomia (birth-weight above 4 kg), shoulder dystocia, low Apgar scores at 5 min (<7) and cesarean section were noted between the groups.
  
  
  CONCLUSIONS
  A value of 200 mg/dL or more in the OGTT is not an indicator of perinatal complications.
