Statistics on Women's Smoking Status at Time of Delivery: England, Q1 2025/26
Official statistics
Summary
This report presents statistics on women’s smoking status at time of delivery, at Sub Integrated Care Board (Sub-ICB), Integrated Care Board (ICB), Local Authority, regional and national levels. This release includes finalised data for quarter 1 of 2025-26 using data from the Maternity Services Dataset (MSDS).
The Smoking at Time of Delivery (SATOD) data collection ceased after Q4 2024-25 following a period of dual reporting with data from the MSDS. From Q1 2025-26 SATOD v1 reporting (data from the historical data source) has been replaced with SATOD v2 data from MSDS. This decision has been based on how closely the estimates have aligned during dual reporting, a Health and Social Care Statistics consultation carried out in 2024 (link available in Related Links below) and being driven by the need to reduce burden on data collection and duplication across the NHS. MSDS data is submitted monthly by Trusts so sub-ICBs (or other commissioning entities) are no longer required to submit data for this collection from Q1 2025-26. A Methodological Change Notice to explain this change has been published, and is available in the Related Links section below.
If you would like to send any feedback on the SATOD publication using solely the MSDS, then please contact us on: [email protected]
