Birth spacing and infant mortality in Brazil

Area of Science:

• Public Health
• Demography
• Epidemiology

Background:

• Infant mortality remains a critical public health concern globally.
• Evidence suggests birth spacing influences child survival outcomes.
• South American countries share similar demographic and health challenges.

Purpose of the Study:

• To analyze the relationship between birth spacing and infant mortality in Brazil.
• To compare Brazilian mortality models with those from other South American nations.
• To identify key variables and interactions affecting neonatal and post-neonatal mortality.

Main Methods:

• Statistical modeling using Brazilian demographic and health data.
• Comparative analysis of mortality models across South American countries.
• Identification of significant predictors for neonatal and post-neonatal mortality.

Main Results:

• The effects of birth spacing on infant mortality in Brazil were consistent with broader South American patterns.
• A simplified model identified three significant variables for neonatal mortality.
• A more complex model revealed four significant interactions influencing post-neonatal mortality.

Conclusions:

• Birth spacing is a significant determinant of infant mortality in Brazil.
• The identified mortality predictors offer insights for targeted public health interventions.
• Findings support the development of region-specific strategies to improve infant survival.
