ABSTRACT: Objective: To present the research protocol and to describe the preliminary results of the Bruminha Project. Methods: This project is part of the set of health actions proposed under the Brumadinho Health Project. It is a prospective cohort study with periodic follow-ups for four years. The eligible population was all children aged 0 to 6 years living in four rural communities of the affected municipality. Sociodemographic and health data were collected, as well as urinary samples, for assessment of exposure to metals. Results: In the first year of study, we evaluated 62% (217) of the eligible population and collected 172 (79%) valid urine samples. At least one metal was detected in all samples, and in 50.6% (n=87) or them, the metal concentration was higher than the reference value. In 38% (n=82) of the children, neuropsychomotor development was considered at risk. Report of respiratory allergy was four times (4.27) more frequent and of bronchitis 62% higher (1.62) in children living in locations exposed to dust from ore residues, compared to those living more than 10 km away from the site of the dam disaster. Conclusion: The study protocol was proven adequate to evaluate the proposed outcomes. The strategy used for population selection required adjustments regarding the long-term community awareness process, with new participants in the upcoming follow-ups (2022 and 2023).
