We aimed to determine the prevalence of HBV and HCV infection in Iranian blood donors based on the present published literature. METHODS A meta-analysis was carried out based on the results of an electronic literature search in the international and national databases for all articles published until October 2020. We selected studies that had appropriate sampling and valid statistical analysis as well as proper measurement methods. The heterogenic indices of the studies were determined using Cochran\u2019s (Q) and I-square (I2) tests. According to the heterogeneity results, a fixed or random-effects model was implemented to estimate the pooled prevalence of HBV and HCV. Meta-regression was conducted to explore the suspected sources of heterogeneity. RESULTS We included 61 and 58 eligible studies related to HBV and HCV, respectively. The pooled prevalence of HBV was 0.57% (95% confidence interval (CI): 0.47 \u2013 0.67, I2: 99.9%) among the blood donors. The range of prevalence rates of HBV was between 0.10% and 2.34% in different areas of Iran. The pooled prevalence of HCV was 0.22% (95% CI: 0.20 \u2013 0.24, I2: 98.64%) in blood donors, which varied between 0.02% and 1.09% in separate locations. Subgroup and meta-regression analyses revealed that the year of publication, geographical location, and quality of the studies probably generated the heterogeneity. CONCLUSION The prevalence of HBV and HCV decreased steadily in Iranian blood donors during the past two decades. It should be asserted that most of the health policies and safety measures taken in recent years in Iran have been effective and promising.<\/jats:p>","DOI":"10.34172\/mejdd.2021.231","type":"journal-article","created":{"date-parts":[[2022,1,27]],"date-time":"2022-01-27T05:50:48Z","timestamp":1643262648000},"page":"237-252","update-policy":"https:\/\/doi.org\/10.34172\/crossmark_policy","source":"Crossref","is-referenced-by-count":9,"title":["Prevalence of HBV and HCV Infections in Iranian Blood Donors; An Updated Systematic Review and Meta-Analysis"],"prefix":"10.34172","volume":"13","author":[{"given":"Leila","family":"Kasraian","sequence":"first","affiliation":[{"name":"Department of Fars Blood Transfusion Research Center, Shiraz University of Medical Sciences, Shiraz, Iran"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mohammad Hossein","family":"Imanieh","sequence":"additional","affiliation":[{"name":"Gastroenterohepatology Research Center, Shiraz University of Medical Sciences, Shiraz, Iran"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Reza","family":"Tabrizi","sequence":"additional","affiliation":[{"name":"Non-Communicable Diseases Research Center, Fasa University of Medical Sciences, Fasa, Iran"},{"name":"Health Policy Research Center, Institute of Health, Shiraz University of Medical Sciences, Shiraz, Iran"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Reza","family":"Shahriarirad","sequence":"additional","affiliation":[{"name":"Student Research Committee, Shiraz University of Medical Sciences, Shiraz, Iran"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Amirhossein","family":"Erfani","sequence":"additional","affiliation":[{"name":"Student Research Committee, Shiraz University of Medical Sciences, Shiraz, Iran"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sahar","family":"Hosseini","sequence":"additional","affiliation":[{"name":"Student Research Committee, Shiraz University of Medical Sciences, Shiraz, Iran"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"20123","published-online":{"date-parts":[[2021,5,26]]},"reference":[{"key":"R1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jiph.2015.05.004"},{"key":"R2","unstructured":"WHO.
