Abstract：Objective To analyze the population change trend,population characteristics and blood sample test re-sults of voluntary blood donors aged 56-60 year in Jinan region,to clarify their blood donation potential and blood safety,and to provide data support for optimizing recruitment strategies and supplementing blood supply.Methods A total of 5,796 voluntary blood donors aged 56-60 years who donated blood voluntarily at Jinan Blood Supply and Security Center from July 1,2012 to June 30,2024 were selected as the research subjects.Data including the total number of voluntary blood donors,the number and frequency of blood donors aged 56-60,and their proportions relative to the total number and fre-quency of voluntary blood donors during the same period were collected to reflect the population change trend.Meanwhile,demographic characteristics such as gender,educational level and occupation,as well as the disqualification rate of blood sample tests were also gathered.Results From July 2012 to June 2024,the number,frequency and corresponding pro-portions of voluntary blood donors aged 56-60 years in Jinan region showed an overall upward trend.Specifically,the pro-portion of the number of donors aged 56-60 years increased from 0.54%in the period of July 2012-June 2013 to 1.54%in July 2023-June 2024,and the proportion of donation frequency of this age group rose from 0.58%to 2.12%during the same time frame.Among these donors,the proportion of males was higher than that of females.In terms of educational composition,those with primary school education accounted for the lowest proportion,while the proportions of those with junior high school,senior high school or technical secondary school,and college education or above were relatively bal-anced.Regarding occupation distribution,the proportion of other occupations was the highest;farmers and workers consti-tuted the core occupational groups,while public servants,company employees and medical staff accounted for relatively low proportions.A total of 46 cases of blood samples were disqualified,with an overall disqualification rate of 7.94%.Among the disqualification causes,the disqualification rate of alanine aminotransferase(ALT)was 3.45%,that of hepati-tis B virus(HBV)1.55%,that of hepatitis C virus(HCV)0.86%,that of treponema pallidum(TP)2.76%,and that of human immunodeficiency virus(HIV)0%.Conclusion From July 2012 to June 2024,the scale of voluntary blood do-nors aged 56-60 years in Jinan region expanded steadily with stable population characteristics and high blood safety,indi-cating a strong potential to serve as a supplementary source of blood supply.
