Insights
Anemia affects over 60% of Xavante children in Brazil, particularly those under two years old. Factors like household size and village group are linked to lower hemoglobin levels, highlighting health inequities.
Area of Science:
- Public Health
- Pediatrics
- Nutritional Epidemiology
Background:
- Anemia is a significant global health issue, especially in vulnerable populations.
- Indigenous communities often face unique challenges impacting child health and nutrition.
- Understanding specific determinants of anemia in the Xavante population is crucial for targeted interventions.
Purpose of the Study:
- To identify and analyze factors associated with anemia in Xavante children.
- To utilize path analysis to elucidate direct and indirect relationships influencing hemoglobin levels.
- To provide evidence for addressing health disparities in Indigenous children in Brazil.
Main Methods:
- Cross-sectional survey conducted in 2011 among Xavante children (6 months to 5 years).
- Collection of hemoglobin levels, anthropometric data, and socioeconomic/demographic information.
- Application of path analysis to a theoretical model, using WHO anemia cut-off points.
Main Results:
- High prevalence of anemia (61.1%) in evaluated Xavante children.
- Anemia was more severe in children under 2 years (78.1%) and moderately/severely affecting those under 5 (33.7%).
- Significant direct associations found between higher child age, larger household size, and specific village groups with lower hemoglobin levels.
Conclusions:
- Anemia disproportionately affects younger Xavante children, those in larger households, and specific village groups.
- Socioeconomic, demographic, historical, and biological factors contribute to anemia prevalence.
- The study underscores the existence of health inequities experienced by Indigenous peoples in Brazil.
Objective:
The objective was to evaluate the factors associated with anemia in Xavante children from the Pimentel Barbosa Indigenous Territory (IT) in Central Brazil through path analysis.
Methods:
A survey was conducted with children between 6 months and 5 years in the Pimentel Barbosa Indigenous Reserve in 2011. Hemoglobin levels, anthropometric measurements, and socioeconomic/demographic data were collected, and cut-off points were recommended by the World Health Organization in 2024. A theoretical model was adapted from previous literature, and direct and indirect associations were evaluated on a theoretical-scientific basis through path analysis. A significance level of 5% was considered.
Results:
Approximately 61.1% of the Indigenous children evaluated had anemia (33.7% < 5 years old had moderate/severe anemia and 78.1% < 2 years old had anemia). The final model presented an acceptable fit. Significant and direct relationships were observed between children's age (β = 0.460), the number of residents in the household (β = -0.143), the village group (β = -0.346) and hemoglobin levels.
Conclusion:
According to their hemoglobin levels, anemia was more prevalent in children under 2 years of age, as well as in children living in the most populous households and the newest village groups, than in the other groups. These findings point to the existence of socioeconomic, demographic, historical, and biological determinants of the prevalence of anemia. In addition, this study showed that Indigenous peoples in Brazil experience health inequities.

Factors Affecting Erythropoiesis
Several factors influence the erythrocyte production rate, with tissue oxygen level being among the most critical. Intense exercise or high altitudes can cause tissue hypoxia, which triggers the kidneys to release more erythropoietin (EPO) into the bloodstream.

Disorders of Erythrocytes
Erythrocyte disorders can be broadly categorized into two main types: anemic and polycythemic conditions.
A low oxygen-carrying capacity of the blood due to the loss, lower production, or destruction of erythrocytes is termed anemia. Hemorrhagic anemia, for example, occurs when bleeding from an external wound or internal ulcer reduces erythrocyte counts.
