Smoking and pregnancy

Women who smoke have increased risks for delay in conceiving, infertility, pregnancy complications, premature birth, spontaneous abortion and stillbirth. Infants born to women who smoke during pregnancy have a lower average birth weight than infants born to women who do not smoke. The risks for sudden infant death syndrome (SIDS) are increased among the infants of women who smoke during pregnancy. Women who quit smoking before or during pregnancy reduce the risk of such adverse reproductive outcomes. For pregnant women, smoking is also likely to put their babies at risk for poor lung development, asthma and respiratory infections.
