RT Journal Article SR Electronic T1 The continuing decline in SIDS mortality JF Archives of Disease in Childhood JO Arch Dis Child FD BMJ Publishing Group Ltd and Royal College of Paediatrics and Child Health SP 625 OP 626 DO 10.1136/adc.2007.116194 VO 92 IS 7 A1 Mitchell, Edwin A A1 Hutchison, Lynne A1 Stewart, Alistair W YR 2007 UL http://adc.bmj.com/content/92/7/625.abstract AB The “Back to Sleep” campaign resulted in a dramatic decrease in sudden infant death syndrome (SIDS) worldwide. SIDS mortality has continued to decline (in New Zealand by 63% from 1993 to 2004), but the reason for this has not been explained. A postal survey found that the proportion of infants sleeping on their back has increased substantially (from 24.4% in 1992 to 72.3% in 2005), and this could account for the 39%–48% decrease in SIDS mortality.
