Abstract：Objective To analyze the distribution characteristics and laboratory test results of blood donors of different age groups in Dongguan City,and to provide a basis for formulating scientific and reasonable voluntary blood donation recruitment strategies and improving blood quality.Methods Data and blood test results of 492 580 blood donors of different age groups in Dongguan City from January 1,2020 to December 31,2024 were selected for statistical analysis.Results The average age of blood donors in Dongguan City increased from 38.72 to 40.67 years from 2020 to 2024,showing a trend towards middle-aged and elderly donors.There were statistically significant differences in age,donation frequency,gender,blood type,occupation,and donation volume among blood donors of different age groups(P<0.001).Among them,the proportion of donors aged 35-44 years was the highest(32.42%-38.04%),and the proportion of donors under 35 years old was mainly first-time donors.Multiple linear regression showed that female gender was positively correlated with donation age(β=0.680,P<0.001),while first-time donors,medical staff,and 200 mL donation volume were negatively correlated with donation age(β=-0.914,-0.443,-0.337,all P<0.001).Blood test results showed that the total unqualified rate was the highest in the 45-54 age group(1.61%),and alanine aminotransferase(ALT)was the top unqualified item in four age groups except for the 45-54 age group,with the highest ALT unqualified rate(0.85%)in the 25-34 age group.The unqualified rate of hepatitis B virus(HBV)in the 45-54 age group(0.69%)was significantly higher than that in other groups,with a statistically significant difference(P<0.001).Conclusion Blood donors in Dongguan City are showing a trend towards middle-aged and elderly donors,with the 35-44 age group being the main force of blood donation.Special attention should be paid to the high-risk group of ALT/HBV in the 45-54 age group,and precise health education and age-specific recruitment strategies should be implemented to ensure the sufficiency and safety of clinical blood supply.
