Our briefing paper on smoking in pregnancy has been updated. Smoking in pregnancy increases the risk of stillbirth, miscarriage, low birth weight, and poor growth and development of the baby, which can lead to ill-health during childhood and adulthood, as well as increasing the risk of complications during pregnancy and labour. Women who smoke at the time of pregnancy are therefore encouraged to stop. Women can also gain long-term health benefits from stopping smoking both for themselves and for the child in terms of reduced exposure to secondhand smoke. The paper investigates recent trends and how Norfolk compares to England.
