Both diabetes and obesity are related to poor health outcomes of coronavirus disease 2019 . Approximately half of COVID-19 mortalities involved individuals with metabolic and vascular disorders. 1 Therefore, special attention should be paid to this population. A previous meta-analysis 2 including 24 cohort studies showed that odds ratios (ORs) of obesity for intensive care unit admission and invasive mechanical ventilation were 1.21 and 2.05, respectively. However, since obesity and diabetes are inter-related conditions, the effects of diabetes cannot be eliminated when analyzing the impact of obesity in data including both diabetic and non-diabetic subjects.

Nikniaz et al. 3 reported useful findings in a paper entitled "Diabesity associates with poor COVID-19 outcomes among hospitalized patients, " which was based on their prospective hospital-based registry of COVID-19 patients in East Azerbaijan, the Iranian province with the highest prevalence of obesity (over 26.3%). 4 This study analyzed data from subjects who were diagnosed with diabetes prior to COVID-19. They showed that obesity (body mass in- Korea demonstrated that the use of dipeptidyl peptidase-4 inhibitor was significantly associated with better clinical outcomes of COVID-19. 5 Therefore, further detailed analysis adjusting for diabetes status is necessary to determine a direct association between obesity and COVID-19 outcomes.

A higher degree of obesity was related to higher all-cause mortality among individuals with type 2 diabetes. 6 During hospitalization for COVID-19, mortality was greater in severe obesity (BMI ≥ 40 kg/m 2 ) even compared to subjects with BMI of 35-39.9 kg/m 2 . 7 This dose-dependent association between obesity and various outcomes of COVID-19 needs to be confirmed in subjects with diabetes and obesity. In addition, multi-ethnic group
