        The “Back to Sleep” campaign resulted in a dramatic decrease in SIDS worldwide. SIDS mortality has continued to decline (in New Zealand by 63% from 1993 to 2004), but 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 39% - 48% decrease in SIDS mortality.
