Correlation between demographic characteristics and blood donation behavior of whole blood donors in Dongguan / 中国输血杂志

ABSTRACT

【Objective】 To explore the influencing factors of repeated blood donation through statistical analysis of demographic characteristics and blood donation behavior of blood donors, so as to provide data support for the formulation and adjustment of blood donor recruitment and retention strategies. 【Methods】 Whole blood donors in Dongguan from 2016 to 2019 were classified and defined. The data of gender, age, occupation, education level, number of blood donors, frequency of blood donation and interval of blood donation were extracted. The descriptive analysis methods such as logistic regression analysis and constituent ratio were used for retrospective analysis. 【Results】 There were 216 543 whole blood donors in Dongguan from 2016 to 2019, of which males, females, first-time blood donors, repeated blood donors and lapsed blood donors accounted for 62.3%(134 823/216 543), 37.7%(81 720/216 543), 27.4%(59 408/216 543), 9.7%(20 912/216 543) and 57.6% (124 699/216 543), respectively, and the proportion of first-time blood donors and lapsed blood donors was relatively high. Gender, age, occupation and education level were the influencing factors of repeated blood donation, among which age showed less impact while education level and occupation showed a greater impact. 【Conclusion】 Donors who are male, aged 26~45, with stable occupation, college degree or above, and with donation interval within 2 years(especially returned in the first year) are the key groups to be recruited and retained. As for students, the special group, who aged 18~25, with college degree or above and first-time blood donors within the first year, corresponding measures should be formulated to increase the retention rate of blood donors, reduce the recruitment cost and improve the re-donation rate.
