Definition of SIDS

An expert panel convened by the National Institutes of Child Health and Human Development defined SIDS as:[2]

  • Sudden death of an infant under 1 year of age, and

  • Cause of death unclear after thorough case investigation, including performance of a complete autopsy, examination of the death scene, and a review of the clinical history.

The American Academy of Pediatrics use the following definition for unexplained sudden death in infancy or SIDS:[3]

  • 'The sudden unexpected death of an apparently healthy infant aged <1 year, in which investigation, autopsy, medical history review, and appropriate laboratory testing fail to identify a specific cause, including cases that meet the definition of SIDS'.
