初次单采血小板献血者人群特征及献血行为追踪

Abstract: Objective To explore the demographic characteristics and blood donation behavior of first-time single donor platelet (SDP) donors in Guangzhou. Methods Information was collected from first-time SDP donors at a blood collection site in Guangzhou during 2023. The demographic characteristics were analyzed, and blood donation behavior were tracked. The χ 2 test was used to compare the differences in rates between groups. A multivariate Logistic regression model was employed to analyze the impact of previous whole blood donation experiences on subsequent SDP donation behavior, after adjusting for basic characteristics. Results Among the 594 first-time SDP donors, the majority were male (66.3%) and aged 18～35 years (84.0%), with 56.7% having previous whole blood donation experience. The χ2 test showed that those with prior whole blood donation experience had a higher proportion of females, a lower proportion of younger individuals, a lower proportion of students, and a lower likelihood of future non-participation in blood donation compared to those without donation experience. Logistic regression analysis indicated that those with prior whole blood donation experience were more inclined to donate whole blood and mix donation again, while males were more likely than females to donate SDP again. Conclusion This study analyzed the demographic characteristics of first-time SDP donors in Guangzhou. Donors with prior whole blood donation experience differed in demographic characteristics from those without and were more likely to make subsequent whole blood and mix donation. Males were more likely than females to donate SDP again. These findings provide research support for the targeted recruitment and intervention strategies for local SDP donors.
