Measure: Smoking during pregnancy by Indigenous status
Description
Age-standardised percentage of mothers who smoked tobacco during pregnancy, by Indigenous status
Data source
National Perinatal Data Collection (NPDC) for the 3-year period 1 January 2016 to 31 December 2018 (2016–2018)
Region types reported
Australian Statistical Geography Standard (ASGS) regions: Indigenous regions (IREGs); States and Territories; Australia.
Suppression rules
Percentages with a numerator of less than 5 have been suppressed for confidentiality reasons. Consequential suppression has also been applied where required to prevent back-calculation.
Data have been suppressed if the denominator for the percentage was less than 100, due to concerns about the reliability of percentages based on small denominator.
Age-standardised rates have been suppressed if: the denominator for any age-specific rate was less than 100; if the numerator for each age group was less than 5; or the total number of all mothers was less than 30.
Notes
All valid data for women with a recorded smoking status who gave birth in 2016, 2017 and 2018 were included.
The denominator for the percentages excludes mothers whose smoking status during pregnancy was not stated.
Age-standardised rates by Indigenous status are reported for the following region types: States and Territories, and Australia. For other region types (e.g. IREG), numbers are too small to support reliable age-standardisation.
Age-standardised rates were directly age-standardised to the Australian female population aged 15–44 as at 30 June 2001 using 5-year age groups (i.e. 15–19, 20–24, 25–29, 30–34, 35–39, 40–44).
Women who gave birth multiple times following multiple pregnancies during the three years from 2016 to 2018 were counted multiple times. Women who gave birth to multiple babies following one pregnancy were only counted once.
