NUTRITIONAL ANEMIA MORTALITY IN BRAZIL: AN ECOLOGICAL STUDY FROM 2012 ONWARD 2021

Abstract

This study analyzed mortality due to nutritional anemias in Brazil from 2012 to 2021, using data from the Mortality Information System (SIM) of the Unified Health System (SUS). Mortality rates for nutritional anemias were calculated for each Brazilian state and analyzed by age group, gender, race/ethnicity, and educational level. The data were evaluated using a generalized linear model with Poisson distribution. The results revealed an average mortality rate of 2.79 deaths per 100,000 inhabitants, with some states showing rates above the national average, such as Paraíba (PB) and Acre (AC). Iron deficiency was the predominant cause of anemia, accounting for 40.47% of cases. Mortality was also observed to be higher among older individuals and those with lower educational levels. These findings underscore the need for targeted interventions to prevent and control nutritional anemias, especially among the most vulnerable groups.
