General description

This analysis is based on women who had valid smoking data at both initial assessment and birth. As smoking status is recorded at two points in time only, the data will not show if mothers were smoking throughout the duration of their pregnancy, or how frequently they smoked. For the purpose of this release analysis, those mothers who were recorded as smoking at initial assessment but not smoking at birth are classed as mothers who ‘stopped smoking’ during pregnancy.
In 2021, 81% of records had valid data, the lowest since data collection began. This is largely due to Hywel Dda not supplying any data for smoking at birth and Cwm Taf Morgannwg having relatively low data completeness.
84% of records had valid data in 2020, largely as a result of missing data for smoking at birth in Hywel Dda, Cwm Taf Morgannwg and Powys. Between 2016 and 2019, there was good data completeness with more than 94% of records with valid data.

Full details of every data item available on both the Maternity Indicators dataset and National Community Child Health Database are available through the NWIS Data Dictionary: http://www.datadictionary.wales.nhs.uk/#!WordDocuments/datasetstructure20.htm

From 1st April 2019 health service provision for residents of Bridgend local authority moved from Abertawe Bro Morgannwg to Cwm Taf.
