Objective: Identify the factors associated with infant deaths due to congenital anomalies in Brazil between 2011 and 2020.
Method: Population-based study with data from the Mortality Information System, including all infant deaths due to congenital abnormalities. Maternal sociodemographic variables and fetal, pregnancy, childbirth, and death characteristics were analyzed, adjusting the Poisson multiple regression model.
Results: Increased risk of death from congenital anomaly: maternal age between 35 and 40 years (RR: 1,30; 1,25-1,36) and over 41 years old (RR; 2,03; 1,91-2,16), reside in the Northern regions (RR: 1,29; 1,21-1,37), Northeast (RR: 1,22; 1,16-1,29), Midwest (RR: 1,16; 1,09-1,24) and Southeast (RR: 1,16; 1,10-1,22), birth by cesarean (RR; 1,56; 1,51-1,62) and gestational age between 32 and 36 weeks (RR; 1,18; 1,15-1,23).
Conclusion: The results show regional inequalities and obstetric factors that influence infant deaths due to congenital abnormalities, pointing to the need for qualified prenatal care.
