Continuous Glucose Monitoring Use in Youth with Type 2 Diabetes: A Pilot Randomized Study
Authors' conclusion
CGM was a feasible and acceptable adjunct to diabetes self-care among >50% of Y-T2D prescribed infrequent SMBG monitoring. Unwillingness to wear a device and social stigma impeded device use.
Study context
- Population
- Youth-onset T2D prescribed self-monitoring of blood glucose (SMBG) ≤twice daily; 82% female, 68% Black, 14.9 ± 3.8 years, BMI 36.2 ± 7.7 kg/m², hemoglobin A1c (HbA1c) 7.4 ± 2.4%52 screened eligible
- Participants
- 18 / 10 / 8
- Comparison
- Continuous glucose monitoring (CGM) vs fingerstick monitoring
- CGMn = 18
- Controln = 10reference
- Control-CGMn = 8
- Primary endpoint
- Feasibility (recruitment, study participation and retention >60%) and acceptability (CGM wear time ≥60% at end of study)
- Follow-up
- 12 weeks
Methodological detailspilot, parallel, randomized 2:1, optional 4-week extension (Control-CGM)
