Who is affected by SIDS

The incidence of sudden infant death syndrome (SIDS) dropped throughout the 1990s, but it remains the leading cause of death for babies younger than 6 months of age.1

  • The SIDS rate in Canada is about 1 out of every 2,000 live births.2 The SIDS rate fell about 68% in Canada between 1990 and 2000.3 A national "Back to Sleep" educational campaign that publicized the importance of placing babies to sleep on their back was launched in 1999 to help educate parents and further drop the rate.4
  • In Canada, the SIDS rate is higher for Aboriginal populations.2
  • The rate of SIDS deaths in other countries varies, in part because SIDS is not defined consistently throughout the world.
