Abstract:
【Objective】 To study the risk factors of blood donors confirmed to be positive for syphilis, so as to avoid highrisk groups, guide the recruitment of blood donors and improve blood safety. 【Methods】 From September 2021 to August 2022, 44 514 blood samples were screened using two enzyme-linked immunosorbent reagents for syphilis, and the reactive samples were confirmed by TPPA. Blood collection time, blood collection location, blood donation numbers, gender, age, marital status and educational level of blood donors were taken as the prediction risk factors, and factors with statistically significant differences by univariate Logistic regression analysis were further analyzed using multivariate factor Logistic regression analysis to determine the final independent risk factors. 【Results】 A total of 121 syphilis antibody reactive samples were detected by enzyme-linked immunosorbent assay, and 64 were confirmed positive by TPPA. Excluding those with incomplete information, a total of 44 505 blood donors were included in the analysis. Logistic regression analysis showed that there were statistically significant differences in blood collection location, blood donation numbers, age and education level. 【Conclusion】 Based on the analysis results of risk factors of syphilis positive blood donors in Wuhu, it is necessary to strengthen the consultation of blood donors in blood donation sites. The high-risk groups are first-time blood donors over 50 years old, with education level of junior high school or below.
