Resumo:
Apesar da inexatidão conceitual e métodos de aferição, a OMS estima que cerca de 10% da população mundial apresente alguma forma de deficiência. Com a finalidade de investigar a prevalência e etiologia das deficiências e verificar se elas estariam associadas à endogamia, foi realizado um estudo epidemiológico transversal com uso do método do informante envolvendo cinco municípios do Estado do Rio Grande do Norte, no Nordeste brasileiro; nos quais foram estimadas frequências de casamentos consangüíneos que variam de 9 a 32%. A prevalência média estimada para deficiências nos cinco municípios amostrados foi de 4,53%, obtida por meio de entrevistas envolvendo 37,87% de uma população de 39.054 habitantes. Em média, 25% dos casais consangüíneos e 12% dos não-consanguíneos apresentaram um ou mais filhos com alguma deficiência. A elevada prevalência de pessoas com deficiência no Nordeste brasileiro pode ter associação com a manutenção da tradição de casamentos consangüíneos nessas populações e parte dessas deficiências pode ser causada por doenças genéticas.

Abstract:
The WHO estimates, despite of different methodological conceptions and inaccurate measurements, that about 10% of world population has a kind of disability. In order to investigate the prevalence and etiology of disabilities and to evaluate if they could be associated with inbreeding, we performed a cross-sectional epidemiological study using the method of the informant in five communities of Rio Grande do Norte, Northeast Brazil, in which consanguineous marriages frequencies varied in the range between 9 and 32%. The mean rate of disabilities in the five sampled communities was 4.53%, obtained by interviews that involved 37.87% of all together 39,054 inhabitants. All together, 25% of consanguineous and 12% of unrelated couples had one or more children with disabilities. The increased rate of individuals with disabilities in Northeast Brazil could be associated with the maintenance of the tradition of consanguineous marriages in these populations and some of these disabilities may be caused by genetic disorders.
