The Effects of Second-hand Smoke in New Borns Clinical Trial
Official title:
Mothers Learning About Second-hand Smoke - MLASS Study
Exposure to second-hand smoke during pregnancy and early infancy leads to low birth weight
and childhood illnesses. 50% of all newborns in the UK are exposed to tobacco smoke due to
maternal smoking or contact with second-hand smoke.
The purpose of this study is to test the feasibility of delivering and evaluating the
effectiveness of a Smoke Free Homes (SFH) health education intervention with pregnant women
and mothers with newborns to reduce unborn and newborn babies exposure to second-hand smoke.
The intervention will be delivered through routine antenatal and postnatal healthcare
settings provided by midwifery and health visiting services.
The intervention consists of educational materials to be given to the woman and a
conversation held between the woman and midwife/health visitor about protecting the baby
from second-hand smoke. The development of the intervention has been informed by the views
of health professionals and service users, incorporates behaviour change theory and has
drawn on other SFH materials developed for other settings. Different parts of the
intervention will be delivered at different points along the antenatal and postnatal care
pathway. 200 pregnant women and their newborns will be recruited.
We will measure salivary cotinine levels to assess the level of exposure to SHS in women and
urinary cotinine levels in newborns. We plan to conduct a before-and-after study of the
delivery of the intervention to test the feasibility of delivering, and methods to evaluate
the effectiveness of the intervention.
Feasibility study outputs:
- A standardised, acceptable, feasible and appropriate health education intervention to
protect unborn and newborn babies exposure to second-hand smoke at home, capable of
being integrated into routine midwifery and health visiting practice
- A trial protocol to evaluate the effectiveness of the intervention on unborn and
newborn babies' exposure to secondhand smoke.
