| Objective To analyze the current situation and influencing factors of voluntary blood donation among college students in Chengde area under the background of sudden public health emergencies. Methods From October to December 2023, a cross-sectional survey was conducted using stratified random sampling method（based on the regional distribution of universities, types of colleges, and the ratio of undergraduate and vocational colleges） to select 1 875 students from three universities: Hebei Petroleum Vocational and Technical University, Hebei Tourism Vocational College, and Chengde Medical College. A questionnaire survey was conducted on the demographic characteristics and blood donation related information of students. According to the attitude towards voluntary blood donation, it was divided into the willing group and the unwilling group. A statistical survey was performed on the current situation of college students’ willingness to donate blood without compensation; the demographic characteristics and blood donation related information of students with different blood donation intentions were compared; a multivariate logistic regression model was used to analyse the reasons affecting college students’ willingness to donate blood without compensation; a predictive model for voluntary blood donation intention was established based on multiple factor results and its fitting degree was analyzed. Results Out of 1 875 college students, 871（46.45%） were willing to donate blood for free, while 1 004（53.55%） were unwilling. The proportion of willing groups with blood donation experience, selfless dedication as the reason for blood donation, and having received blood donation from others was higher than that of unwilling groups. The proportion of worried about infectious diseases during the blood collection process, fearing that it would affect physical health, and not allowing physical conditions was lower than that of unwilling groups（P ＜0.05）. Logistic regression analysis showed that having blood donation experience, selfless dedication, having received blood donations from others, being attracted by blood donation benefits as a priority for blood donors and their immediate family members, being proud of their dedication, having good knowledge about blood donation, and being willing to promote blood donation were protective factors for college students who were willing to donate blood without compensation. However, being physically unhealthy, worrying about infectious diseases during the blood collection process, fearing that it would affect physical health, not allowing physical conditions, and inconvenient blood donation were risk factors（P ＜0.05）. It was feasible to establish a predictive model for college students' willingness to donate blood without compensation based on multiple factor results. Conclusion Under the background of sudden public health emergencies, a relatively high proportion of college students in Chengde are unwilling to donate blood without compensation. The influencing factors are mainly related to their blood donation experience, personal values, the impact of blood donation on their physical health, and blood donation publicity. Therefore, it is necessary to strengthen the publicity of voluntary blood donation knowledge for college students to increase their willingness to donate blood. |
