A Descriptive and Geospatial Analysis of Environmental Factors Attributing to Sudden Unexpected Infant Death

Area of Science:

• Forensic Pathology
• Public Health
• Epidemiology

Background:

• Sudden unexpected infant death (SUID) remains a significant public health concern.
• Understanding the circumstances and environmental factors contributing to SUID is crucial for prevention strategies.

Purpose of the Study:

• To identify circumstances and environmental factors associated with SUID.
• To conduct geospatial analyses to pinpoint areas with a high concentration of infant deaths.
• To explore modifiable factors that could reduce infant mortality.

Main Methods:

• Analysis of medicolegal death investigation records and autopsy reports (n=732) over a 10-year period.
• Geospatial analysis to identify geographic clusters of SUID.
• Examination of environmental factors, including co-sleeping practices and socioeconomic indicators.

Main Results:

• Co-sleeping on various surfaces was prevalent in 53.4% of SUID cases.
• Areas with the highest number of infant deaths were characterized by high poverty levels.
• Environmental factors contributing to SUID were identified as potentially modifiable.

Conclusions:

• Modifiable environmental factors, particularly co-sleeping and socioeconomic conditions, play a role in SUID.
• Enhanced data collection during investigations, including details on co-sleeping, substance use, and household conditions, may improve SUID risk identification.
• Targeted interventions in high-poverty areas and education on safe sleep practices are recommended to reduce infant mortality.
