Purpose The purpose of this study was to explore knowledge and attitudes of health program students towards ethical issues pertaining to the beginning and the end of human life, and associations between these attitudes and demographic variables. Participants and Methods The study took a mixed-method approach with self-administered survey questionnaires and in-depth interviews. A total of 88 students participated in the survey, and 10 students participated in interviews. The study was conducted among students in the Health Extension Program at a Christian university in Papua New Guinea. Results Students showed a higher acceptance of abortion than euthanasia. More year-4 students presented significantly deeper knowledge of euthanasia and abortion compared to year-1 students. There were no gender differences regarding knowledge and attitude towards these two bioethical issues. The majority of students opposed the idea of women’s right to abortion, which is attributed mainly to socio-cultural reasons. The qualitative analysis indicated a very strong perception that having children ‘defines’ womanhood and also revealed general disapproval of any form of euthanasia. A low level of acceptance of various forms of euthanasia is associated with a respect for older people in Melanesian society and beliefs that ancestors’ support is required for achieving prosperity in life. Conclusion The study offered a comprehensive description and analysis of students’ knowledge and attitudes towards ethical issues pertaining to the beginning and the end of human life. Presented a low level of knowledge towards bioethical issues, together with a small proportion of the knowledge gained from lectures and tutorials, indicated inadequate teaching of bioethics and calls for further improvement. In the perspective of rapid social and cultural changes in the Papua New Guinea society, further studies on changing attitudes towards bioethics issues would be valuable.
