Abstract

Background and objectives: Maternal substance use during pregnancy heightens risk of sudden unexpected infant death (SUID), including through unsafe sleep practices. Families impacted by substance use frequently experience disproportionate social drivers of poor health and family vulnerability likely contributory to fatality risk. Characteristics of sleep-related SUID among infants born prenatally substance exposed versus nonexposed were compared to identify targeted prevention opportunities.

Methods: Using the Sudden Death in the Young Registry, we examined SUID with sleep-related death between 2015 and 2020 across infants prenatally exposed versus nonexposed. Distribution of sleep environment characteristics, social drivers of poor health, and family vulnerability factors were examined using descriptive statistics and χ2.

Results: Of 2010 infants who experienced sleep-related deaths, 283 (14%) were prenatally exposed. More than half of deaths involved an adult bed (52%, n = 1045) or surface sharing with an adult (53%, n = 1074). Supervisors of prenatally exposed infants were disproportionately impaired at infant death versus nonexposed (34%, n = 97 vs 16%, n = 279). Statistically significant associations between prenatal exposure history and vulnerability factors (insurance, child welfare involvement, intimate partner violence, health care barriers) were identified (P < .05).

Conclusions: Sleep-related SUID across infants prenatally exposed versus nonexposed differ in sleep environment characteristics and contributory social vulnerability. Disproportionate sleep environment hazards (surface sharing, supervisor impairment) are identified among prenatally exposed infants that should compel targeted prevention efforts, including safe sleep messaging, discouraging surface sharing, and engaging support persons during impairment periods. Addressing social needs and family vulnerability are also paramount to increase access to health care, safe sleep education, and material resource provision.
