The term Sudden Infant Death Syndrome (SIDS) was first introduced in 19691 and was further refined to a SIDS definition in 1991.2 SIDS has historically been defined as the sudden and unexplained death of an apparently healthy infant up to one year of age that remains unexplained after a thorough case investigation.

SIDS is now defined as the sudden and unexplained death of an apparently healthy infant younger than one year of age that remains unexplained after a thorough case investigation including the performance of a complete autopsy, examination of the death scene and review of the clinical history. It is the leading cause of death for infants during the postneonatal period.
