Between 25-50% of female smokers quit smoking after they discover they are pregnant. But why do the remainder continue to smoke throughout their pregnancy?
Do they not know that smoking during pregnancy is harmful? They usually do. One of our UK studies, that included pregnant women both motivated and unmotivated to quit, found 99% agreed to some degree with the statement ‘smoking during pregnancy can cause serious harm to my baby’ with around 75% agreeing very much or extremely. Yet less than 10% of them were abstinent 12 weeks later. While making a quit attempt is more likely among those with strong ‘harm beliefs’ about smoking in pregnancy, it does not appear to increase the chances of success.
