Abstract
Background and purpose: The association between ABO blood types and Coronavirus disease 2019 (COVID-19) have been investigated in several studies but there are inconsistencies in results The purpose of this study was to investigate the association between ABO blood types and COVID-19 infection based on serologic results Materials and methods: A cross-sectional seroepidemiologic study was carried out in 1504 people
living in Mazandaran province, north of Iran Blood samples were drawn to determine blood groups Also, IgG and IgM antibodies were measured by ELISA Data analysis was done using Chisquare, Fisher’s exact test, univariate and multivariate logistic regression analyses in SPSS V25 Results: The frequency of IgG positive among blood groups A, B, AB, and O was 12 7%, 11 8%, 9 4%, and 9 6%, respectively After adjusting for suspicious confounding factors, the odds ratio of COVID-19 infection was 1 19 (95% CI:0 85-1 67) in blood group A, 1 33 (95% CI:0 94-1 87) in blood group B, 0 82 (95% CI:0 44-1 55) in blood group AB, and 0 70 (CI 95%:0 50-0 98) in blood group O based on serologic results (IgG+/IgM+) Conclusion: The odds ratio for COVID-19 was significantly lower (30%) in blood group O compared to other blood groups, so blood group O can be considered as a protective factor against COVID-19 [ABSTRACT FROM AUTHOR] Copyright of Journal of Mazandaran University of Medical Sciences (JMUMS) is the property of Mazandaran University of Medical Sciences and its content may not be copied or emailed to multiple sites or posted to a listserv without the copyright holder's express written permission However, users may print, download, or email articles for individual use This abstract may be abridged No warranty is given about the accuracy of the copy Users should refer to the original published version of the material for the full abstract (Copyright applies to all Abstracts )
