Objective: Identify factors associated with malaria in indigenous populations. Methods: Data referring to cases from the state of Amazonas, Brazil were obtained from the Epidemiological Surveillance Information System for Malaria and from the Mortality Information System. In the analysis, the notification years formed a period from 2007 to 2016. The cases were classified according to the probable location where infection occurred. For ordinal variables, the chi-square trend test was performed. For multivariate analysis, stepwise logistic regression was used. Results: A total of 1,055,852 cases of malaria were notified in the state of Amazonas, from 2007 to 2016. This state has the highest proportion of indigenous peoples and malaria in Brazil. Among the factors that associate malaria and indigenous peoples, the most significant were male sex, people under 40 years of age and high levels of parasitemia. The magnitude of P. vivax infection is higher than P. falciparum. In regards to mortality, 109 deaths were registered. Conclusion: Malaria in indigenous populations differs from that in non-indigenous populations owing to their lifestyle and behavior and affects younger age groups. The indigenous groups inhabit places where access is difficult and where there are limited health facilities. The municipalities on the frontier which have larger indigenous populations have a higher percentage of cases of malaria.

Objetivo: Identificar os fatores associados ?? mal??ria em popula????o ind??gena. M??todos: Os dados foram obtidos do Sistema de Informa????o para a Vigil??ncia Epidemiol??gica de Mal??ria e do Sistema de Informa????es sobre Mortalidade, referente aos casos do estado do Amazonas, Brasil. Na an??lise foram considerados os anos de notifica????o formando uma s??rie do per??odo de 2007 a 2016. Os casos foram estratificados conforme o local prov??vel de infec????o. Para as vari??veis ordinais realizou-se o teste qui-quadrado de tend??ncia. Para an??lise multivariada foi utilizado a regress??o log??stica em stepwise. Resultados: foram notificados 1.055.852 casos de mal??ria no Amazonas, de 2007 a 2016. Esse ?? o estado com maior propor????o de ind??genas e de mal??ria no Brasil. Dentre os fatores associados ?? mal??ria em ind??genas, foram significativos: sexo masculino, idade menor que 40 anos, altas parasitemias e resultado de exame com P. vivax, infec????o mista, P. malariae e P. ovale. No que se refere a mortalidade por mal??ria foram notificados 109 ??bitos. Conclus??es: A mal??ria em ind??genas difere dos n??o ind??genas devido ao comportamento e estilo de vida, afetando a faixa et??ria mais jovem. Os ind??genas ocupam lugares de dif??cil acesso e com poucos recursos de sa??de. Os munic??pios de fronteira e com mais popula????o ind??gena apresentaram maiores percentuais dos casos de mal??ria.
