Outcome Measures

Primary Outcomes (2)

  • Changes in Glucose Variability

    Glucose variability as measured by glucose excursions from CGM

    From first pregnancy visit to delivery

  • Change(s) in Behavior and/or Concerns of Diabetics.

    Change(s) in behavior and/or concerns of diabetics as detected by the hypoglycemia fear questionnaire. Behavior sub-scale score ranges from 10-50, with higher scores indicating more behavioral changes in the participant's daily routine to avoid low blood sugar. Worry sub-scale score ranges from 17-85, with higher scores indicating more worry or concerns because of low blood sugar. Total score ranges from 27-135, with higher scores for both sub-scales indicating more fear and a worse outcome.

    From first pregnancy visit to delivery

Secondary Outcomes (2)

  • Change in A1C.

    From first pregnancy visit to delivery

  • Evaluation of Maternal and Fetal Outcomes.

    From first pregnancy visit to delivery
