Sudden infant death syndrome, abbreviated SIDS, is an unexplained rapid (and unexpected) death of a person less than one year old, that is not explained after a full autopsy, correlations with the death scene and the (clinical) history.[1]

Pathogenesis

It is not understood. One hypothesis for SIDS is: immaturity of the arcuate nucleus of medulla (which control respiratory frequency).[1]

Risk factors

Parent:

  • Low socioeconomic status.
  • Maternal substance use.[2]

Child:[2]

  • Male.[3]
  • Prematurity.
  • Low birth weight.
  • IUGR.
  • Prone sleep, i.e. put to sleep on the front.
  • Soft bed mattress.

Note:

  • Breast feeding reduces the risk.[4]
