The Use of Continuous Glucose Monitoring in Comparison to Self-Monitoring of Blood Glucose in Gestational Diabetes: A Systematic Review
Authors' conclusion
Continuous glucose monitoring offers substantial advantages over SMBG for managing GDM by providing continuous, real-time glucose data, enabling timely treatment adjustments. These findings support the integration of CGM into clinical practice to improve maternal and neonatal outcomes in GDM. Further research is needed to establish standardized CGM metrics specific to GDM management.
Study context
- Population
- Women with gestational diabetes mellitus (GDM); RCTs, observational and prospective cohort studies comparing continuous glucose monitoring (CGM) and self-monitoring of blood glucose (SMBG)35 studies
- Comparison
- CGM vs SMBG
- Outcome
- Glycemic control: key glycemic metrics such as TIR and glycemic variability (GV), and their associations with maternal and neonatal outcomes

Pooled result
As reported in the abstract
- CGM vs SMBG: significant improvements in maintaining time in range (TIR) and reducing glycemic variability (GV)
- Improvements correlated with favorable maternal and neonatal outcomes, including lower rates of large-for-gestational-age infants, preterm birth and NICU admissions
Further pooled results
Detection of hyperglycemic and hypoglycemic events
- CGM detected more hyperglycemic and hypoglycemic events, particularly nocturnal fluctuations
