Exposure to second-hand smoke (SHS) during pregnancy and early infancy leads to low birth weight and childhood illnesses [1, 2]. 50% of all newborns in the UK are exposed to tobacco smoke due to maternal smoking or contact with SHS . The evidence to support specific measures to implement smoking restrictions and reduce SHS exposure at home during pregnancy and the neonatal period is limited .
Our aim is to test the feasibility of delivering and evaluating the effectiveness of a Smoke Free Home (SFH) health education intervention with pregnant women and mothers with newborns to reduce unborn and newborn babies exposure to SHS.
The SFH intervention is designed to help women learn about the hazards of SHS, evaluate their own smoking behaviour, and empower them to negotiate smoking restrictions at home. The intervention will be delivered by midwives and health visitors during routine appointments at different points along the antenatal and postnatal care pathway.
We will measure salivary cotinine levels to assess the level of exposure to SHS in women who do not smoke during pregnancy. Urinary cotinine samples will also be collected in the newborns before and after the last delivery of the intervention.
A structured questionnaire will be used to assess the level of smoking restrictions at home.
Focus group discussions (FGD) with mothers who received the intervention will investigate their views on the appropriateness, acceptability and feasibility of the intervention in this setting. FGDs with health professionals and interviews with key health service managers will investigate the key constraints and drivers in the delivery & integration into routine practice for SFH.
