Abstract: Objective To explore current status of laboratory safety cognition among students in a medical university and analyze the relevant influencing factors. Methods In undergraduate and graduate students with more experimental courses, a unified questionnaire was used and the answers were statistically analyzed. Results The accuracy range in the laboratory situation was 72.46%-93.68%, and the awareness rate was 85.58%.The accuracy range was 22.32%-96.52% in personal laboratory experience, 42.19% in awareness rate, and 65.27% in overall awareness rate. The differences of gender, age, grade and major were significant(χ²=16.07,χ²=51.84,χ²=92.79,χ²=13.84,P<0.05). Logistic analysis showed that gender(OR=0.718, 95% CI=0.606-0.851), age(OR=1.335, 95% CI =1.204-1.480)and major(OR=1.243, 95% CI=1.039-1.486)were the main influencing factors for the status of laboratory safety cognition. Conclusion Students in this university have a high degree of cognition about the laboratory situation, but the level of laboratory knowledge still needs to be improved. Therefore, supervision should be strengthened to eliminate potential safety hazards.
