Carbohydrate nutritional knowledge and diabetes outcomes according to different modes of insulin administration in people living with type 1 diabetes from the French SFDT1 cohort
Authors' conclusion
Better carbohydrate knowledge is independently associated with improved glycemic control in PwT1D using CSII but not among those using MDI or AID systems.
Study context
- Population
- People living with T1D in the French SFDT1 cohort; median age 43 [IQR 32–54] years, T1D duration 25 [14–36] years
- Participants
- 635 people
- Exposure
- Carbohydrate knowledge and time in range (TIR) by insulin delivery mode: Multiple daily injections (MDI), continuous subcutaneous insulin infusion (CSII), automated insulin delivery (AID)
- MDIn = 158
- CSIIn = 255
- AIDn = 222
- Outcome
- Association of carbohydrate knowledge (GluciQuizz, 36 points) with glycemic control (TIR, 70-180 mg/dl)
- Follow-up
- 14-day TIR
Main finding
As reported in the abstract
Association of total GluciQuizz score with TIR
- Overall population: β ± SE
- 0.04 ± 0.01; P < 0.001
- CSII: β ± SE
- 0.06 ± 0.02; P < 0.001
- MDI: not significant
- P = 0.19
- AID: not significant
- P = 0.55
Observational data: associations, not effects.
Further findings
