Comments:Help on this term

Data elements are from the Perinatal National Minimum Data Set (NMDS) or have been provided as voluntary non-standardised items by the states and territories. Records with data that are missing, not stated or not interpretable have been excluded from the denominator.

Standardised data collection for smoking in pregnancy commenced for births from July 2010. This will enable reporting against parts (a) among all females who gave birth the proportion who reported smoking tobacco in the first 20 weeks of pregnancy, and (b) among all females who gave birth the proportion who reported smoking after 20 weeks of pregnancy and reported smoking at any time during pregnancy.

National Perinatal Data Collection (NPDC) data on smoking status and/or smoking quantity (number of cigarettes smoked) have been collected from New South Wales, Queensland, South Australia and Australian Capital Territory since 2001, and progressively from all other jurisdictions.
