Overview of the Indigenous health of the Yanomami ethnic group in Brazil: A Public Health Emergency.

Introduction: The Indigenous population of the Yanomami ethnic group in Brazil is currently facing a public health emergency due to the high number of deaths, mainly of children. Taking that into consideration, this study aims to analyze this crisis impact on the health of this population in the period between 2018 and 2022.

Methods: The data presented were collected from the report called Yanomami Mission ("Missão Yanomami") published by the Brazilian Ministry of Health and, from it, a descriptive analysis of the Indigenous individuals' health was carried out for (i) the geographical distribution; ii) the number of deaths; (iii) the child death rate; (iv) the deaths of Indigenous individuals from preventable causes; (v) the causes of preventable diseases related to hygiene and basic sanitation, and the distribution of diarrheal diseases according to age groups; (vi) evaluation of the nutritional classification; vii) the percentage (%) of the complete vaccination scheme, and (viii) the coverage of prenatal appointments of Indigenous pregnant women.

Results: The report included 31,017 individuals belonging to the Yanomami ethnic group, most of the participants were up to 39 years old (N = 26,377; 85.0%) and men (N = 15,836; 51.1%). During the period described in the report, the number of deaths reached 1285/31,017 (4.1%). When analyzing the deaths, the most representative age groups were those of children under 1 year old (505/1285; 39.9%), from 1 to 4 years old (178/1285; 13.8%), and the elderly from 60 to 79 years old (150/1285; 11.6%). The Indigenous individuals from this ethnic group presented a child death rate ~ 1.5 to 3.5 higher than that of the total Indigenous population in the country. Regarding the child death rate, the neonatal component represented 57.8% of the deaths and, in 2022, 93.0% of the pregnant women had less than six prenatal appointments. This population shows a high number of deaths due to preventable causes (N = 538) and cases of illnesses associated with hygiene and sanitation, for example (N = 35,103 cases/notifications). As for vaccination, the full vaccination scheme targeting children below 5 years old has not been met since 2018.

Conclusion: In the Indigenous population of the Yanomami ethnic group, a high number of deaths was observed, which affected mainly individuals under 1 year old. Among the factors associated with the deaths, mainly in children under 5 years old, most cases have preventable causes, which could be reduced by proper action promoting their health and preventing diseases.
