Continuous Glucose Monitoring Metrics in Asians Without Diabetes: Differentiating Prediabetes From Normoglycemia
Authors' conclusion
Asians with NG spend most of their time within TIR 54 to 140. TAR140 may be a useful metric for distinguishing prediabetes from NG.
Study context
- Population
- Healthy Asian adults without diabetes151 analysed
- Participants
- 160 adults
- Exposure
- Normoglycemia vs prediabetes
- Prediabetesn = 27
- Outcome
- Reference intervals (2.5th–97.5th percentiles) for CGM metrics in NG
Methodological detailsblinded continuous glucose monitoring (CGM)
- Blinded CGM
Main finding
As reported in the abstract
- Mean glucose
- 78-106 mg/dL
- TIR 70 to 180 mg/dL
- 69%-100%
- TIR 54 to 140 mg/dL
- 86.4%-100%
- TAR >140 mg/dL
- 0%-9.7%
- SD
- 10.9-25.6 mg/dL
Observational data: associations, not effects.
Further findings
Diagnostic performance of CGM metrics for prediabetes vs normoglycemia (NG)
- TAR140 had the highest area under the receiver operating characteristic (AUROC) among CGM metrics
- 0.72
- TAR140 optimal threshold
- 5.6%
