Smoking & Health Issues

Smoking and Pregnancy

Women who quit smoking before or during pregnancy reduce the risk of adverse reproductive outcomes.

Women who smoke have more difficulty becoming pregnant and have a higher risk of never becoming pregnant. Women’s smoking during pregnancy increases the risks for pregnancy complications, premature birth, spontaneous abortion and stillbirth.

Babies of mothers who smoked during pregnancy on average have lower birth weights. Low birth weight babies are at greater risk for childhood and adult illnesses and even death. Women who quit smoking before the third trimester (the last 3 months) of their pregnancy are more likely to have babies who are close to normal weight.

Smoking by pregnant women can cause sudden infant death syndrome (SIDS). According to the 2004 US Surgeon General’s Report, infants whose mothers smoked before and after birth are at three to four times greater risk for SIDS, and babies exposed to secondhand smoke after birth are at twice the risk.

When mothers smoke during pregnancy, it hurts their babies’ lungs. Infants of mothers who smoked during pregnancy have reduced lung function and may have increased frequency of lower respiratory tract illness. They may also have increased risk for impaired lung function in childhood and adulthood. For pregnant women, smoking could also put their babies at increased risk of asthma and respiratory infections.
