Gender and educational attainment influence willingness to donate organs among older Nigerians: a questionnaire survey

Introduction: disparity between the demand for and the supply of organs for transplantation remains a major public health issue of global concern. This study evaluated the knowledge and determinants of willingness to donate organs among outpatient clinic attendees in a Nigerian teaching hospital. Methods: a 43-item semi-structured interviewer-administered questionnaire was designed to assess awareness and willingness of individuals attending Neurology, Psychiatry and Geriatrics Outpatient clinics to donate bodily organs for transplantation. Association between participants' characteristics and willingness towards organ donation was investigated using logistic regression models. Results: a total of 412 participants were interviewed and mean age was 46.3 (16.1) years. There were 229 (55.6%) females and 92.5% had at least 6 years of formal education. Overall, 330 (80.1%) were aware of donation of at least one organ for transplantation purposes but only 139 (33.7%) were willing to donate organ. In analyses, adjusting for sex, marital status, family setting and educational status, male gender AOR [2.066(1.331-3.2016)] secondary education [AOR 5.57 (1.205-25.729) p= 0.028] and post-secondary education [AOR-6.98 (1.537-31.702) p= 0.012 were independently associated with willingness towards organ donation. Conclusion: the survey revealed high level of awareness but poor willingness towards organ donation among older Nigerians attending outpatient clinics of a premier tertiary hospital. Male gender and educational attainment were significantly associated with willingness to donate. Educational programs that particularly target women and less educated older Nigerians are needed to promote organ donation in Nigeria.
