Stress, Depression, and Unhealthy Behavior Changes among Patients with Diabetes during COVID-19 in Korea

The government ordered various restrictions to limit the spread of coronavirus disease 2019 (COVID-19), thus, affecting the mental health status and lifestyle of people with diabetes. This study identifies COVID-19 effects on mental health problems and unhealthy behavioral changes among patients with diabetes. The subjects of this cross-sectional study were adults aged 19 years or older who participated in the 2020 Korean Community Health Survey. Stress, depression, and changes in unhealthy behavior in diabetic patients (N = 26,839) because of COVID-19 were compared with controls (N = 26,834). The association between stress and depression and unhealthy behaviors among patients with diabetes was investigated. During the COVID-19 pandemic, 20.3% and 4.2% of diabetic patients reported higher levels of stress and depression, respectively, than controls. Diabetic patients showed decreased physical activity and sleep time, and increased smoking. Among diabetic patients, stress and depression are associated with unhealthy behavior changes during COVID-19. Measures to promote healthy lifestyles along with stress and depression management strategies must be implemented for the health care of diabetic patients during the pandemic.
