Analysis of glycemic control in diabetic patients by monitoring HbA1c levels before, during and after Covid-19 confinement in Auvergne, France
Authors' conclusion
Confinement had no impact on HbA1c levels in diabetic patients.
Study context
- Population
- Diabetic patients >18 years with ≥1 HbA1c test before and after confinement, medical analysis laboratories in Auvergne, France; HbA1c measurements March 17, 2019 to May 11, 2021
- Participants
- 70,286 patients
- Exposure
- HbA1c before vs after COVID-19 confinement
- Outcome
- HbA1c

Main finding
As reported in the abstract
Observational data: associations, not effects.
Further findings
HbA1c reduction in year after confinement, preconfinement HbA1c ≥ 9 % · year following confinement
- Larger median reduction in HbA1c
- 0.90 % points
HbA1c test performed during confinement
- Patients tested during confinement
- 24.5 %
- Majority of those tested were >80 years with preconfinement average HbA1c 7–9 %
Average HbA1c increase ≥1 percentage point after confinement
- Patients with increase
- 5.1 %
- At risk of glycemic imbalance after confinement: age ≤ 64, insufficient blood tests before confinement, HbA1c imbalance before confinement
