Abstract：
We assessed university students\' knowledge, attitude, and practice toward blood donation and identified the factors that promote or hinder their willingness to donate. We employed a multicenter cross-sectional design, collecting data from August to October 2022 through self-administered questionnaires available in Arabic and English. Both online (Google Forms) and paper surveys were utilized. Data were analyzed using R Statistical Software (v4.1.3; R Core Team 2022). A total of 12,606 university students (7966 females and 4640 males) from 16 countries completed the questionnaire; of them, 28.5% had a good knowledge level regarding blood donation, and 22.7% had donated blood at least once. Students in health science colleges had significantly more awareness of blood donation (p-value < 0.001), but there were no significant differences in practice (p-value = 0.8). Barriers to donation included not being asked (37%), medical ineligibility (33%), fear of pain or infection (18%), concerns about negative health effects (18%), difficulty accessing donation centers (15%), and medical mistrust (14%). Individuals aged > 20 years had significantly higher odds of possessing a high knowledge level (adjusted odds ratio [aOR] 1.77, p < 0.001). Private and international university enrollment was associated with increased knowledge (aOR 1.19, p-value < 0.001 and aOR 1.44, p-value = 0.003), while non-health science college students had lower odds (aOR 0.36, p < 0.001). Regarding blood donation status, participants > 20 years old were more likely to donate (aOR 2.21, p < 0.001). Conversely, being female, having congenital or chronic diseases, and possessing low knowledge levels were associated with decreased odds of blood donation (all p < 0.05). University students show insufficient knowledge about blood donation, with health science students displaying higher awareness levels. Despite their positive attitudes, blood donation rates remain low across all disciplines. It is imperative to enhance education and accessibility to foster a culture of blood donation among students.
摘要：
我们评估了大学生的知识，态度,和实践献血，并确定了促进或阻碍他们献血意愿的因素。我们采用了多中心横截面设计，通过阿拉伯语和英语的自我管理问卷收集2022年8月至10月的数据。使用了在线（GoogleForms）和纸质调查。使用R统计软件(v4.1.3;R核心团队2022)分析数据。共有来自16个国家的12606名大学生(7966名女性和4640名男性)填写了问卷；其中，28.5%的人有良好的献血知识水平，22.7%的人至少献血一次。健康科学学院的学生对献血的认知度明显更高（p值<0.001），但实践中没有显著差异(p值=0.8).捐赠的障碍包括不被要求(37%)，医疗不合格(33%)，害怕疼痛或感染（18%）对健康负面影响的担忧(18%)，难以接近捐赠中心（15%），和医疗不信任(14%)。年龄>20岁的个体拥有高知识水平的几率显著较高(调整后的优势比[aOR]1.77,p<0.001)。私立和国际大学的入学率与知识的增加有关（aOR1.19，p值<0.001和aOR1.44，p值=0.003），而非健康科学大学生的几率较低(aOR为0.36，p<0.001)。关于献血状况，>20岁的参与者更有可能捐献(aOR2.21,p<0.001).相反，作为女性，患有先天性或慢性疾病，知识水平低与献血几率降低相关(均p<0.05)。大学生对献血的认识不足,健康科学学生表现出更高的意识水平。尽管他们态度积极,所有学科的献血率仍然很低。必须加强教育和可及性，以在学生中培养献血文化。
