目的 了解高校在校学生自动体外除颤器（AED）的知信行情况，并分析其影响因素。方法 于2023年5—8月，采用方便抽样的方法，对北京6所高校1 447名在校学生进行问卷调查。收集一般情况、AED了解情况以及AED知信行等信息，采用logistic回归分析AED知信行的影响因素。结果 共调查1 447人，平均年龄（22.51±4.73）岁。调查人群中有123人（8.50%）完全没听说过AED，有867人（59.92%）知道AED及其作用但不会操作，仅有68人（4.70%）会操作使用AED。AED知信行得分[中位数（四分位数间距）]为62(55～68)分。logistic回归分析结果显示，未参加过急救培训（OR=0.71,95%CI=0.52～0.97）、不知道施救行为的法律保障（OR=0.72,95%CI=0.56～0.91）、不知道周围AED配置情况（OR=0.69,95%CI=0.53～0.89）的高校在校学生AED知信行得分较低。知道AED及其作用但不会操作（OR=1.97,95%CI=1.50～2.57）、会操作使用AED(OR=4.51,95%CI=2.36～8.64)的高校在校学生AED知信行得分较高。结论 调查人群对AED的掌握程度有限，但知信行水平较好，曾是否参加过急救培训、AED了解情况、对施救行为法律保障的知晓情况以及对周围AED配置知晓情况是AED知信行的影响因素。

Objective To investigate the knowledge, attitude, and practice(KAP) about automated external defibrillators(AEDs) among college students and analyze the influencing factors. Methods From May to August 2023, a questionnaire survey was conducted among 1 447 students selected by convenient sampling from 6 universities in Beijing. The information on demographic characteristics, understanding of AEDs, and KAP of AEDs was collected.Logistic regression analysis was employed to analyze the factors influencing KAP of AEDs. Results A total of 1 447 students were investigated, with an average age of(22.51 ± 4.73) years. Among the population surveyed, 123(8.50%)individuals had never heard of AEDs; 867(59.92%) individuals were aware of AEDs and their functions but were unable to operate AEDs; only 68(4.70%) individuals were capable of operating AEDs. The median(interquartile ranges) of KAP score about AEDs was 62(55, 68). The logistic regression analysis revealed that participants who had never participated in first aid training(OR = 0.71, 95%CI: 0.52–0.97), were unaware of the legal protection associated with rescue action(OR = 0.72, 95%CI: 0.56–0.91), and lacked knowledge about the availability of AEDs around them(OR =0.69, 95%CI: 0.53–0.89) scored lower in KAP about AEDs. Conversely, participants who were aware of AEDs and their functions but could not operate AEDs(OR = 1.97, 95%CI: 1.50–2.57) and those who could operate AEDs(OR = 4.51,95%CI: 2.36–8.64) demonstrated higher scores in KAP about AEDs. Conclusions The study indicates that the population has limited knowledge of AEDs but a good level of KAP. Factors such as participation in first aid training,awareness of AEDs function, understanding of legal protection for rescue action, and knowledge of the availability of AEDs around them significantly influence the KAP about AEDs.
