Background As the country with the 7th largest number of People with Diabetes MESHD ( PWD MESHD) in the world, the COVID-19 MESHD COVID-19 MESHD pandemic, and the Large Social Scale Restriction (LSSR) policy taken by the Indonesian government to reduce the number of COVID-19 MESHD transmissions is estimated to interfere diabetes MESHD management and will increase the incidence of diabetes complications MESHD. This study aims to determine the difficulties of diabetes MESHD management and its impact on diabetes MESHD morbidity during the COVID-19 pandemic MESHD in Indonesia. Methods This study is a cross-sectional study using a national scale web survey. This research was conducted in Indonesia enrolling 1,124 PWD MESHD aged 18 years or older. Diabetes complications MESHD are defined as any incidence of hypoglycaemia, or Diabetic Foot Ulcer MESHD ( DFU MESHD), or hospital admission experienced by PWD MESHD in Indonesia during the COVID-19 pandemic MESHD. The correlation between diabetes MESHD management difficulties and diabetes MESHD-related complications was measured using a modified cox regression test. Results Diabetes MESHD management difficulties were experienced by 69.8% of PWD in Indonesia MESHD. The difficulties include attending diabetes MESHD consultation 30.1%, access to diabetes MESHD medication 12.4%, checking blood sugar levels 9.5%, controlling diet 23.8%, and performing regular exercise 36.5%. Diabetes MESHD-related complications occurred in 24.6% of subjects. Those who had diabetes MESHD management difficulties during the COVID-19 pandemic MESHD are prone to have diabetes MESHD complications by 1.4 times greater (PR: 1.41, 95% CI: 1.09-1.83) than those who did not. Conclusion The COVID-19 pandemic MESHD and LSSR have a substantial impact on diabetes MESHD management and indirectly increased diabetes morbidity in Indonesia MESHD.
