Sudden unexpected death in infancy  (SUDI) is defined as “a death occurring suddenly in a child under 1 year of age, when nothing in the child’s known history could have predicted it”. In France, the Haute Autorité de Santé (HAS) has set the upper age limit at 2 years. The study population of the french registry of SUDI is made up of all children aged 0 to 23 months:

  • who died in France in the context of unexpected infant death
  • treated in a SUDI referral center.
