BACKGROUND: To have a thorough understanding of epidemic surveillance, it is essential to broadenour knowledge of death tolls worldwide. This study aimed to determine the age‑standardized mortalityrate (ASMR) and predictors of mortality among coronavirus disease 2019 (COVID‑19) patients.MATERIALS AND METHODS: In this cross‑sectional design, all COVID‑19 patients with apositive polymerase chain reaction test in the population covered by Arak University of MedicalSciences (AUMS) were entered to the study. Data collection was conducted by phone interview.The study variables comprised age, sex, coronary heart diseases, diabetes, and some symptomsat admission. The adjusted odds ratio (OR) and 95% confidence intervals (CIs) were obtained bylogistic regression. The direct method was applied to calculate ASMR (per 100,000) of COVID‑19.The analysis was applied by STATA software 12.0.RESULTS: A total of 208 cases of COVID‑19 (out of 3050 total infected cases) were dead and2500 cases were recovered. The mean age of dead patients was 70 years. The COVID‑19 fatalityrate in the population equaled 6.8%; in those patients who were 70 years old or more, however, thecase fatality rate was 16.4%. The ASMR of COVID‑19 was 12.9 (CI 95%: 11.2, 14.8). The odds ofCOVID‑19‑related death in the age over 60 were 10.87 (CI 95%: 6.30, 18.75) times than lower 45 yearsold. Moreover, it was observed that COVID‑19 significantly increased the odds of COVID‑19‑relateddeath in diabetes patients (OR = 1.45, CI 95%: 1.02, 2.06, P = 0.036).CONCLUSION: The ASMR of COVID‑19 was relatively higher in males than females. In general, theCOVID‑19 fatality rate was relatively high. We found that older age and diabetes can have impacton the death of COVID‑19, but the headache was found to have a negative association with theCOVID‑19‑related death.
