Postpartum Continuous Glucose Monitoring to Detect Dysglycemia After Gestational Diabetes
Authors' conclusion
Postpartum CGM is a reasonable and convenient initial postpartum screen for postpartum dysglycemia with high completion rates, sensitivity, and acceptability ratings. Percent time in range 70 to 180 mg/dL had strong predictive power for OGTT.
Study context
- Population
- Postpartum women after pregnancy complicated by GDM; 36 ± 6 years old; 40% non-Hispanic white, 24% non-Hispanic black, 22% Asian, 14% Hispanic; 34% Medicaid insuredconsented
- Participants
- 50 women
- Comparison
- Postpartum blinded continuous glucose monitoring (CGM) vs 6-week oral glucose tolerance test (OGTT)
- Outcome
- Detection of postpartum dysglycemia by CGM: return rates, participant experience and power to predict OGTT results
Methodological detailsprospective, blinded CGM
- Prospective
- Blinded CGM
