Introduction: COVID-19 infection has drastically changed the routine lifestyle and physical life of people. These factors pose negative impact on glycemic management in people with diabetes. This study aimed to determine the relationship between glycemic changes, physical activities, and eating behaviors during the COVID-19 pandemic in Japanese patients with type 2 diabetes. Methods: Study involved both retrospective and cross-sectional data analyses. The glycated Hemoglobin (HbA1c) values in patients with type 2 diabetes before the pandemic in 2019 and during pandemic in 2020 were evaluated. A self-administered questionnaire survey was used to measure physical activity and eating behaviors. Patients with type 2 diabetes who had HbA1c values ≥ 7% at any month during 2020 were included. Data collection was performed at the medical outpatient clinic of Kagawa University Hospital. Results: Two hundred participants completed the survey. During the COVID-19 pandemic, the average HbA1c values significantly deteriorated (7.72%) than those pre-pandemics (7.57%), with an increase of 1.98 percent (p=0.002, r= -0.157). Additionally, the scores for All Physical Activities (all PA) decreased and total eating behaviors improved. There was no significant relationship was found between the HbA1 values, physical activities, and eating behaviors during the pandemic. Conclusion: HbA1c levels deteriorated during the COVID-19 pandemic, but this change was unrelated to physical activity or eating habits. The stress factors may contribute to these changes.
