Abstract

Introduction: Suicide is a public health problem in Brazil, with particularly high rates among indigenous peoples, reflecting social, cultural, and territorial inequalities. Objective: To describe suicide incidence among Brazilian indigenous peoples and characterize cases by sociodemographic factors, geographic distribution, and methods used. Method: A systematic review was conducted in eight databases in October 2024, including studies presenting incidence data. Selection and extraction were performed by two independent reviewers, and methodological quality was assessed using the Joanna Briggs Institute tool. Results: Twenty-four studies published between 1991 and 2024 were included, with rates ranging from 0.1 to 111.7 per 100,000 inhabitants. An upward trend was observed, with concentration in the North and Midwest, especially Amazonas and Mato Grosso do Sul. Rates were higher among men and youths aged 10–29 years. Hanging predominated, commonly occurring at home and associated with alcohol use. Conclusion: Elevated suicide rates among indigenous peoples in Brazil reveal marked vulnerabilities and reinforce the need for intercultural policies that address the social and cultural determinants of this phenomenon.
