Implication

Retrospective cohort study examines maternal smoking's impact on sudden unexpected infant death in the US, implying a need for early cessation support.

Key Points

This study aims to investigate how different patterns of maternal smoking during pregnancy relate to sudden unexpected infant death (SUID).
Conducted a population-based retrospective cohort study of live births in the US from 2017 to 2021.
Utilized CDC Linked Birth-Infant Death files for data collection.
Categorized maternal smoking into several behaviors: non-smoking, pre-pregnancy only, trimester-specific, and smoking intensity.
Employed multivariable logistic regression to analyze associations with SUID.
Heavy continuous smokers showed the highest adjusted odds ratio (aOR 2.81) for SUID.
Light continuous smokers had an aOR of 2.47 for SUID, while discontinuous heavy smokers had an aOR of 2.29.
Pre-pregnancy-only smokers had the lowest odds of SUID, with an aOR of 1.77 for light smokers and 1.61 for heavy smokers.
Sensitivity analyses indicated the indirect effects of continuous smoking on SUID through gestational age and infant birth weight were insignificant.
