Interplay among sleep quality, dinner timing, and blood glucose control in users of advanced technologies: A study in a cohort of adults with type 1 diabetes
Authors' conclusion
The rate of hypoglycemia and dinner timing are key factors affecting both sleep quality and glycemic control in adults with T1D. Addressing lifestyle habits, including dinner timing and fear of hypoglycemia, may still be needed in users of AID.
Study context
- Population
- Adults with T1D on AID or CSII insulin delivery systemsAID 122, CSII 67 · Adults with T1D on AID 122 · or CSII 67
- Exposure
- Bad-sleepers vs Good-sleepers; Late-eaters vs Early-eaters
- Outcome
- Two-week CGM metrics by sleep quality
Main finding
As reported in the abstract
TBR70-54, Bad-sleepers vs Good-sleepers
2.1 ± 2.0 vs. 1.3 ± 1.2 %
TBR54, Bad-sleepers vs Good-sleepers
0.7 ± 1.0 vs. 0.2 ± 0.4 %
CV, Bad-sleepers vs Good-sleepers
34.4 ± 5.3 vs. 31.8 ± 5.2 %
Observational data: associations, not effects.
Further findings
| Outcome | P value |
|---|---|
| HbA1c and CGM metrics by dinner timingLate-eaters vs Early-eaters | P < 0.05 for all |
- HbA1c and CGM metrics by dinner timing: Higher HbA1c, lower TBR70-54; after dinner higher TAR180-250 and lower TIR70-180 with Late-eaters, particularly among AID users
Multiple regression
- Dinner time was a main predictor of HbA1c
- TBR54 was a main predictor of sleep quality
