Abstract：
BACKGROUND: College and university students were an important population group of blood donors, especially in the current situation of tight blood supply. This study aimed to investigate the current status and determinants of blood donation among this population group in Wuhan using a structural equation model.
METHODS: We conducted a cross-sectional study involving 12 colleges and universities in Wuhan, China, including 5168 students. Sociodemographic characteristics, health status, knowledge about blood donation, and attitude toward blood donation were treated as latent variables, with blood donation as the observed variable. Confirmatory factor analysis was conducted using the Mplus 8.0 statistical software application, followed by the establishment of a structural equation model to assess the relationships that exist between these variables.
RESULTS: The overall blood donation rate among college and university students was 24.71%. The established model indicated that sociodemographic characteristics, health status, knowledge about blood donation, and attitude toward blood donation showed significant positive effects (0.135, 0.056, 0.321, and 0.389, respectively) on blood donation, among them, the direct effects were 0.076, -0.110, 0.143, and 0.389, respectively (P < 0.01). Additionally, sociodemographic characteristics, health status, and knowledge about blood donation had indirectly affected blood donation through the mediating effect of attitude towards blood donation. Their effects on attitude towards blood donation were 0.099, 0.243, and 0.468, respectively. (P < 0.01). The model could explain explained 22.22% of the variance in blood donation behavior among college and university students in Wuhan.
CONCLUSIONS: Blood donation among college and university students in Wuhan was associated with sociodemographic characteristics, health status, knowledge about blood donation, and attitude towards blood donation, with attitude being the primary influencing factor. Tailored recruitment strategies for blood donation among students should prioritize initiatives aimed at enhancing knowledge about blood donation and fostering positive attitudes toward it.

摘要：
背景：大学生是献血者的重要群体，尤其是在目前血液供应紧张的情况下。本研究采用结构方程模型对武汉市该人群的献血现状及其影响因素进行了研究。
方法：我们进行了一项涉及武汉12所高校的横断面研究，中国,包括5168名学生。社会人口统计学特征，健康状况,关于献血的知识，对献血的态度被视为潜在变量，以献血为观察变量。使用Mplus8.0统计软件应用程序进行验证性因素分析，然后建立结构方程模型来评估这些变量之间存在的关系。
结果：大学生总体献血率为24.71%。建立的模型表明，社会人口统计学特征，健康状况,关于献血的知识，和对献血的态度对献血有显著的积极影响（分别为0.135、0.056、0.321和0.389），其中,直接效应分别为0.076、-0.110、0.143和0.389(P<0.01)。此外,社会人口统计学特征，健康状况,献血知识通过献血态度的中介作用间接影响献血。他们对献血态度的影响分别为0.099、0.243和0.468。(P<0.01)。该模型可以解释武汉市大学生献血行为差异的22.22%。
结论：武汉大学生献血与社会人口学特征有关，健康状况,关于献血的知识，以及对献血的态度，态度是主要影响因素。量身定制的学生献血招募策略应优先考虑旨在增强献血知识并培养对献血积极态度的举措。
