Assessment of risk factors associated with sudden death in childhood


  • Sudden unexplained death in childhood (SUDC) and sudden expected death in childhood (SEDC) have similar prevalence rates for risk factors, except for an increased rate of death during sleep for SUDC; febrile seizure (FS) is likely a contributing factor for both.

Why this matters

  • Sudden infant death syndrome (in children age <1 year) is well characterized whereas SUDC (occurring in children age ≥1 year) despite being the fifth leading category of death among toddlers is inadequately studied; there is a clear need for systematic, population-based studies to gain a deeper understanding of mechanisms behind SUDC.
