Identifying and definitional attributes
Metadata item type:	Indicator
Indicator type:	Indicator
Short name:	PI02b-Proportion of Indigenous babies born within the previous 12 months whose birth weight results were low, normal or high, 2013
METEOR identifier:	450666
Registration status:	Health, Superseded 21/11/2013 Indigenous, Superseded 21/11/2013
Description:	Proportion of Indigenous babies born within the previous 12 months whose birth weight results were categorised as one of the following: Low (less than 2,500 grams) Normal (2,500 grams to less than 4,500 grams) High (4,500 grams and over).
Rationale:	Low birth weight (newborn babies weighing less than 2,500 grams) is associated with an increased risk of ill health and is related to higher mortality within the first year of life. Low birth weight is a particular issue for Indigenous Australians. Recording birth weight encourages the provision of appropriate care to limit the negative associations of low birth weight.
