Objective:To investigate the students’cognition and attitude of a medical university to euthanasia, and provide suggestions for promoting medical humanism education in colleges. Method: 301 students were investigated by self-designed questionnaire on cognition and attitude towards?euthanasia, and the data was analyzed by descriptive statistics and Chi-square test. Results: There were significant differences in the students' major and whether or not they had studied the medical ethics in the understanding of euthanasia（χ2=6.15，P<0.05；χ2=40.00，P<0.001）. The percentage of respondents agree with passive euthanasia was 53.2%. The percentage of respondents agree with active euthanasia was 74.8%. Conclusions: Most respondents have basic understanding of euthanasia but lacking a clear and embedded understanding of euthanasia. There are differences among medics with different characteristics. Medical Ethics Education, life education and legal knowledge of euthanasia should be combined with Palliative Care Education to guide medical students to understand death and euthanasia correctly.
