Risk factors for unexpected infant death among very premature infants in France.

Background: Prematurity is one of the risk factors for sudden unexpected infant death (SUID), a phenomenon that remains poorly explained.

Materials And Methods: The analysis of specific factors associated with SUID among very premature infants (VPI) was performed through a retrospective review of data collected in the French SUID registry from May 2015 to December 2018. The factors associated with SUID among VPI were compared with those observed among full-term infants (FTI).
