Identifying and definitional attributes
|Metadata item type:||Indicator|
|Indicator type:||Progress measure|
|Short name:||PI 01–Proportion of babies born of low birth weight, 2021|
|Registration status:||Health, Standard 16/09/2020|
The incidence of low birthweight among live born singleton babies.
|Indicator set:||National Healthcare Agreement (2021) Health, Standard 19/11/2020|
|Outcome area:||Prevention Health, Standard 07/07/2010|
Collection and usage attributes
Low birthweight is defined as less than 2,500 grams.
Excludes multiple births, stillbirths and births of less than 20 weeks gestation.
Analysis by state/territory, remoteness and Socio-Economic Indexes for Areas (SEIFA) Index of Relative Socio-Economic Disadvantage (IRSD) is based on the usual residence of the mother.
Data excludes Australian non-residents, residents of external territories and records where state/territory of usual residence was not stated.
Variability bands are to be calculated using the standard method (see definition under Computation).
Presented as a:
100 × (Numerator ÷ Denominator)
Variability bands: to be calculated using the standard method for estimating 95% confidence intervals as follows:
CI (CR)95% = CR ± 100 × 1.96 × √[((CR/100) × (1 – (CR/100)))/n]
Where n=number of live born singleton babies.
CI = confidence interval
CR = crude rate (expressed as a percentage)
Number of low birthweight live born singleton babies.
|Numerator data elements:|
Number of live born singleton babies.
|Denominator data elements:|
2018—Nationally, by (all not reported):
2018—State and territory, by:
2016–18—State and territory, by (all not reported):
Disaggregation by Indigenous status of the mother and the baby are recommended to be reported using 3-year combined data for the current reporting period due to the small number of low birthweight babies born to Indigenous mothers each year, and the small number of low birthweight Indigenous babies born each year. Single year data (2018) is reported for time series (state/territory by Indigenous status).
Note that data collection methods for Indigenous status of the mother and baby may vary between states and territories.
|Disaggregation data elements:|
Most recent data available for 2021 National Healthcare Agreement performance reporting: 2018 (calendar year data).
Indigenous: Aggregated data (2016 to 2018) is reported for the current reporting period (state and territory).
Single year data (2018) is reported for time-series (state and territory).
Information is included in the National Perinatal Data Collection (NPDC) for all live births and stillbirths of at least 400 grams birthweight or at least 20 weeks gestation. Data for this indicator may therefore include live born terminations of pregnancy of at least 20 weeks gestation.
