RESUMO
Considering the relevance of the migratory processes in Western societies, the attitudes toward organ donation after death are analyzed by means of a survey applied to a representative random sample of the resident immigrant population in Spain, comprising 1202 subjects (estimated margin of error of ± 2.88%, p = q, p < 0.05). Considered variables were disposition toward own organ donation, disposition toward deceased relatives' donation in different situations, arguments against donation, socio-demographic indicators, religious beliefs, social integration, and information about organ donation and transplantation. Predisposition to donate varies strongly across geographical origin and religious beliefs and also shows relationships with additional socio-demographic, social integration, and informative variables. In turn, the relationship between religious beliefs and attitude toward donation varies as a function of the degree of social integration. In Spain, the immigrant population is a heterogeneous collective that requires differential strategies to promote donation. Such strategies should be aimed at reinforcing the existing positive attitudes of citizens from West Europe and Latin America, and at familiarizing and informing about donation in citizens from the East, and at making specific efforts to break down the cultural and religious barriers toward donation in African citizens, with special emphasis on people of the Muslim faith.
