Abstract
Background. Commitment to organ donation may vary among willing younger and older adults. We aimed to understand attitudes toward organ donation among Arab adults.Methods. We conducted a cross-sectional survey of a representative sample of adults from 13 regions in Saudi Arabia between February 12, 2021, and March 14, 2021. We stratified the anal-yses by individuals' age (younger, 18 to 39 years old; older, >= 40 years old). Results. Of 4217 individuals contacted, 3120 respondents (1846 younger and 1274 older) completed the survey, with a response rate of 74%. We found that 54% of younger and 47% of older respondents expressed support for organ transplantation, and 49% of younger and 35% of older respondents wanted to donate their organs. However, only 4% of younger and 3% of older respondents had registered in the national donor database. Knowledge sources that most likely to influence attitudes toward organ donation for younger and older respondents, respectively, were physician/health care worker (58% and 55%), family member (29% and 26%), scientist/ researcher (29% and 22%), and religious scholar (16% and 23%). Conclusion. Though many younger and older adults express a willingness to donate, few are registered to be a donor. Our findings highlight the influential sources of knowledge that can be implemented in future interventions to increase commitment to organ donation.
