Disparities in Glycemic Outcomes Persist in Youth with Type 1 Diabetes and High-Technology Use
Authors' conclusion
Even in a subset of youth with T1D using CGM with high rates of insulin pump use, disparities in glycemic outcomes persist. When evaluating glycemic outcomes, race remained a significant cofactor despite controlling for age, duration of diabetes, sex, insurance status, and insulin administration type. These results add to the existing literature, and demonstrate race remains strong predictor of glycemic outcomes.
Study context
- Population
- Youth with T1D using Dexcom G6 continuous glucose monitor (CGM); 78.2% privately insured, 50.0% on insulin pumps; median age 16.6 (IQR 14.2–18.2) years
- Participants
- 188 participants
- Exposure
- Non-Hispanic White (NHW) vs NHB youth with T1D using CGM
- NHWn = 147reference
- Outcome
- Glycemic metrics from CGM and HbA1c, by race
Main finding
As reported in the abstract
Hemoglobin A1c (HbA1c), NHW vs NHB
7.6% vs. 9.2%
90-day mean glucose, NHW vs NHB
181 mg/dL vs. 220 mg/dL
90-day time >250 mg/dL, NHW vs NHB
16.3% vs. 34.7%
Observational data: associations, not effects.
Further findings
Multiple linear regression predictors of glycemic outcomes
- Significant regression equations for all glycemic outcomes
- P < 0.0001, p=0.0001, and p < 0.0001, respectively
- After adjustment, only race and duration of diabetes independently associated with glycemic outcomes
