Smoking and pregnancy
There is extensive evidence to show that smoking during pregnancy is harmful to unborn babies. The Government has introduced a target to reduce the percentage of women who smoke at birth to 11% or less by the end of 2015.
The number of maternities is defined as the number of pregnant women who give birth to one or more live or stillborn babies of at least 24 weeks gestation, where the baby is delivered by either a midwife or doctor, at home or in an NHS hospital (including GP units). This count is the number of pregnant women, not the number of babies (deliveries). It does not include maternities that occur in psychiatric hospitals or private beds / hospitals.
Women known to be smokers at the time of delivery are defined as pregnant women who reported smoking (at all) at the time of delivery. Women known to be non-smokers at the time of delivery are defined as pregnant women who reported smoking no cigarettes (at all) at the time of delivery. This count does not include women whose smoking status is not known (which is collected separately), or those who intend to give up smoking after delivery.
Percentage of mothers known to be smokers at the time of delivery is:
Number of mothers known to be smokers at the time of delivery / Number of maternities *100.
