SIDS and Sleep-Related Infant Death Statistics

Sudden unexpected infant death (SUID) is the death of an infant less than 1 year of age that occurs suddenly and unexpectedly, and whose cause of death is not immediately known.

Most SUIDs are reported as a sleep-related infant death, including:

  • Sudden Infant Death Syndrome (SIDS)
  • Accidental Suffocation and Strangulation in Bed (ASSB)
  • Undetermined (UND)

In Illinois, although SIDS deaths are decreasing, deaths due to Accidental Suffocation and Strangulation are increasing. This shift may be due to changes in classification of causes of death, or the availability of a more thorough death scene investigation revealing circumstances surrounding each death.

In 2014, more infant deaths due to Undetermined circumstances and Accidental Suffocation and Strangulation in Bed (ASSB) occurred than from Sudden Infant Death Syndrome. Deaths due to ASSB are preventable.
