Sudden infant death syndrome and unascertainable deaths: Trends and disparities among Aboriginal and non-Aboriginal infants born in Western Australia from 1980 to 2001 inclusive

Abstract

Aim: To analyse patterns and trends in mortality from unknown causes (sudden infant death syndrome and unascertainable deaths) for all Aboriginal and non-Aboriginal infants born in Western Australia, 1980-2001.
