Causal pathways to infant mortality: linking social variables to infant mortality through intermediate variables

Area of Science:

• Sociology
• Public Health
• Biostatistics

Background:

• Infant mortality rates are disproportionately high in the African-American community.
• Understanding the complex interplay of social and biomedical factors is crucial for effective interventions.

Purpose of the Study:

• To delineate the pathways through which social factors influence infant mortality within the African-American population.
• To examine the roles of maternal education and marital status as social determinants of infant mortality.

Main Methods:

• Utilized a conceptual model integrating social and biomedical causation.
• Analyzed the influence of maternal education and marital status through intermediate variables.
• Controlled for bio-demographic factors, healthcare utilization, and infant health status at birth.

Main Results:

• Maternal education's impact on infant mortality risk is largely mediated by bio-demographic factors, healthcare access, and infant health at birth.
• Marital status was a significant, though weak, predictor of infant mortality, independent of other examined variables.
• Intermediate variables included maternal age, birth order, birth interval, previous pregnancy outcomes, prenatal care, preterm delivery, and low birth weight.

Conclusions:

• Social factors, particularly maternal education, significantly shape infant mortality risks through various pathways.
• Marital status exerts an independent, albeit minor, influence on infant mortality.
• Addressing social determinants is essential for reducing infant mortality disparities in the African-American community.
