Situational Awareness and Proactive Engagement Predict Higher Time in Range in Adolescents and Young Adults Using Hybrid Closed-Loop
Authors' conclusion
Situational awareness is an independent predictor of TIR and may provide insight into patterns of attention and focus that could positively influence glycemic outcomes in adolescents. Proactive engagements predict better TIR, whereas reactive engagement predicted lower TIR. Future interventions could be designed to train users to develop awareness and expertise in effective diabetes self-management.
Study context
- Population
- Adolescents and young adults (15–25 years) with T1D using Control-IQ HCL; mean age 18 ± 1.86 years, 86% White non-Hispaniccompleted the study
- Participants
- 18 adolescents
- Outcome
- Correlation of behaviors and awareness items with TIR (70-180 mg/dl, 3.9-10.0 mmol/L)
Methodological details2-week prospective study, mixed models
- 2-week prospective study
- Mixed models
Main finding
As reported in the abstract
Predictors of daily TIR (multivariable modeling)
- Underestimated glucose levels: lower time in range (TIR)
- r = −0.22
- More CGM alerts received: lower TIR
- r = −0.31
- More pump engagements: lower TIR
- r = −0.27
- Responded to CGM alerts: higher TIR
- r = 0.20
- Entered carbohydrates into bolus calculator: higher TIR
- r = 0.49
Observational data: associations, not effects.
Further findings
Situational awareness of glucose levels vs time since last glucose check
- Situational awareness did not correlate with time since last glucose check
- P = 0.8
