Comparisons of School-Day Glycemia in Different Settings for Children with Type 1 Diabetes Using Continuous Glucose Monitoring
Authors' conclusion
Although TIR was higher for weekends and virtual school, glycemic metrics improve while in-school, possibly related to beneficial school day routines.
Study context
- Population
- Children 7–12 years with T1D using continuous glucose monitoring (CGM); diabetes duration 3.5±2.5 years, HbA1c 7.5±0.8%
- Participants
- 217 children
- Exposure
- In-school vs weekends vs virtual school glycemia
- Outcome
- TIR and CGM metrics during school hours vs non-school settings
Methodological detailsmultilevel mixed models
- Multilevel mixed models
Main finding
As reported in the abstract
TIR, TAR, mean glucose and SD
- CGM metrics clinically similar across settings
- Weekends vs In-school: P < 0.001
- Virtual school vs In-school: P < 0.001
Observational data: associations, not effects.
Further findings
| Outcome | In-school | Weekends | Virtual school |
|---|---|---|---|
| TIR change from start of school day to later in school day | mean 40.9% to 58.0% | 60.8 to 50.7% | 62.2 to 47.8% |
Hour × setting interaction
- Significant interaction of hour and setting for several metrics
- P < 0.001
Time in range (TIR) change from start of school day to later in school day
- Corresponding decrease in time above range (TAR) in-school; mean glucose similar pattern; little change in SD
Factors associated with higher TIR in-school
- Younger age
- P = 0.006
- Lower HbA1c
- P < 0.001
- Insulin pump use
- P = 0.02
