Performance of Tandem Control IQ During Outdoor Physical Activity in Children and Adolescents with Type 1 Diabetes
Authors' conclusion
No serious or severe hypoglycemic episodes were recorded during PA performed 90 min after lunch.
Study context
- Population
- Caucasian children and adolescents aged 9–18 years with T1D using t:slim X2 with Control-IQ technology, recruited at a local sporting event; low-dose meal insulin (reduced by 50%) 90 min before physical activity (PA)2 refused PA
- Participants
- 26 children
- Exposure
- Endurance then power activities vs power then endurance activities
- Group An = 13
- Group Bn = 11
- Outcome
- TIR during 2-h of outdoor PA
- Follow-up
- 2-h of outdoor PA
Main finding
As reported in the abstract
TIR · 2-h PA
P = 0.39
Observational data: associations, not effects.
Further findings
| Outcome | Group A | Group B | P value |
|---|---|---|---|
| TIR during first sessionSignificantly better TIR in Group B | 17.4% (95% CI 7.3–41.7) | 53.8% (95% CI 30.2–96.1) | P = 0.02 |
- Mean glucose when PA started · start of PA · similar between groups
- P = 0.06
Time in range (TIR) during second session
- TIR increased in both groups
Safety
Serious or severe hypoglycaemia
- Episodes of serious or severe hypoglycemia
- 0
