We conducted a population\u2010based registry study from Death Registration System in the elderly population (<jats:italic>N<\/jats:italic>\u2009=\u2009433\u2009445) from the outbreak that emerged up to May 30, 2021 (before vaccination). We analyzed CFR and mortality rates due to COVID\u201019 as well as the case findings and characteristics in the elderly population. Logistic regression analysis was carried out for the association between COVID\u201019 mortality and effective factors. During the study,\u00a0the province had 18\u2009079 confirmed cases and 4390 deaths. The male to female CFR risk ratio was 3.2. The overall CFR and mortality rates were 24% and 1%, respectively. CFR and mortality ranged from 9.56% to 0.37% in the 60\u201364 age group to 70% and 2.6% in the age group \u226585 years, respectively. We found a significant trend in CFR and mortality of COVID\u201019 with advanced age. Male sex, advanced age, marital status, and living alone were associated with an increased risk of COVID\u201019 fatality. COVID\u201019 mortality measures were higher in the older population of this province. Advanced treatment supports and interventions are needed to reduce mortality rates of COVID\u201019 in the elderly population.<\/jats:p>","DOI":"10.1002\/jmv.27594","type":"journal-article","created":{"date-parts":[[2022,1,15]],"date-time":"2022-01-15T08:28:26Z","timestamp":1642235306000},"page":"2126-2132","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":25,"title":["Case fatality and mortality rates, socio\u2010demographic profile, and clinical features of COVID\u201019 in the elderly population: A population\u2010based registry study in Iran"],"prefix":"10.1002","volume":"94","author":[{"given":"Elham D.","family":"Esmaeili","sequence":"first","affiliation":[{"name":"Road Traffic Injury Research Center Tabriz University of Medical Sciences Tabriz Iran"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ali","family":"Fakhari","sequence":"additional","affiliation":[{"name":"Research Center of Psychiatry and Behavioral Sciences Tabriz University of Medical Sciences Tabriz Iran"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Behrouz","family":"Naghili","sequence":"additional","affiliation":[{"name":"Infectious and Tropical Diseases Research Center Tabriz University of Medical Sciences Tabriz Iran"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Farzad","family":"Khodamoradi","sequence":"additional","affiliation":[{"name":"Department of Epidemiology and Biostatistics, School of Public Health Tehran University of Medical Sciences Tehran Iran"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hosein","family":"Azizi","sequence":"additional","affiliation":[{"name":"Research Center of Psychiatry and Behavioral Sciences Tabriz University of Medical Sciences Tabriz Iran"},{"name":"Department of Epidemiology and Biostatistics, School of Public Health Tehran University of Medical Sciences Tehran Iran"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2022,1,28]]},"reference":[{"key":"e_1_2_11_2_1","doi-asserted-by":"publisher","DOI":"10.1002\/jmv.27072"},{"key":"e_1_2_11_3_1","first-page":"27","article-title":"Modeling and forecasting trend of COVID\u201019 epidemic in Iran until May 13, 2020","volume":"34","author":"Ahmadi A","year":"2020","journal-title":"Med J Islam Repub Iran"},{"key":"e_1_2_11_4_1","doi-asserted-by":"publisher","DOI":"10.7326\/M20-2911"},{"key":"e_1_2_11_5_1","doi-asserted-by":"publisher","DOI":"10.1007\/s15010-020-01538-w"},{"key":"e_1_2_11_6_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.puhe.2021.09.007"},{"key":"e_1_2_11_7_1","first-page":"122","article-title":"Vulnerability and fragility expose older adults to the potential dangers of COVID\u201019 pandemic","volume":"49","author":"Benksim A","year":"2020","journal-title":"Iran J Publ Health"},{"key":"e_1_2_11_8_1","unstructured":"CDCCenters for Disease Control and Prevention Coronavirus disease 2019 (COVID\u201019). 2020."},{"key":"e_1_2_11_9_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jinf.2020.03.005"},{"key":"e_1_2_11_10_1","doi-asserted-by":"publisher","DOI":"10.1186\/s12879-021-06450-8"},{"key":"e_1_2_11_11_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.archger.2020.104058"},{"key":"e_1_2_11_12_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.puhe.2020.10.029"},{"key":"e_1_2_11_13_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.puhe.2020.11.005"},{"key":"e_1_2_11_14_1","unstructured":"JafariN KabirM MotlaghM.
