Sleep-Related Sudden Unexpected Infant Death Among Infants Prenatally Substance Exposed

Area of Science:

• Neonatal Health
• Pediatric Sleep Safety
• Public Health Interventions

Background:

• Maternal substance use during pregnancy is a risk factor for sudden unexpected infant death (SUID).
• Families affected by substance use often face social determinants of health that increase vulnerability.
• Understanding differences in sleep-related SUID is key for prevention.

Purpose of the Study:

• To compare sleep-related SUID characteristics in infants with and without prenatal substance exposure.
• To identify specific risk factors and vulnerabilities for targeted prevention strategies.

Main Methods:

• Analysis of sleep-related SUID cases from the Sudden Death in the Young Registry (2015-2020).
• Comparison of sleep environment, social drivers of health, and family vulnerability factors between exposed and non-exposed infants.
• Descriptive statistics and chi-squared tests were employed.

Main Results:

• 14% of 2010 sleep-related SUID cases involved prenatal substance exposure.
• Unsafe sleep environments, including adult bed or surface sharing, were common.
• Supervisors of exposed infants were more likely to be impaired at the time of death.

Conclusions:

• Sleep-related SUID differs between prenatally exposed and non-exposed infants, highlighting distinct environmental and social vulnerabilities.
• Targeted interventions for prenatally exposed infants should focus on safe sleep practices, discouraging bed-sharing, and support during caregiver impairment.
• Addressing social needs and family vulnerabilities is essential for improving healthcare access and safe sleep education.
