Pregnancy- evidence rating
Smoking is the single most modifiable risk factor for adverse outcomes in pregnancy. It is estimated to contribute to 40% of all infant deaths, a 12.5% increased risk of a premature birth and a 26.3% increased risk of intra-uterine growth restriction. This
therefore remains a key public health concern, particularly since early intervention
(i.e. stopping smoking at three months gestation) significantly improves outcomes.
Pregnant smokers should be offered a full range of services and there should be a robust care pathway that allows women to be tracked through their quit attempts. This should include biochemical verification.
In 2008, 8,409 pregnant women set a quit date in the first two quarters with a success rate of 44%, 25% of which were CO validated
