Passive Smoking And Its Effects On Pregnancy

Exposure to tobacco smoke affects all stages of human reproduction. Tobacco smoking affects both male and female fecundity. Maternal cigarette smoking is associated with increased risks for ectopic pregnancy, premature rupture of membranes, abruptio placentae, placenta previa, miscarriage, stillbirth, preterm birth, low birth weight and congenital anomalies such as cleft lip.

After birth, the risk for sudden infant death syndrome (SIDS) is increased among the offspring of women who smoked during or after pregnancy. Additionally, maternal exposure to secondhand smoke (SHS) in pregnancy has also been associated with a modest reduction in birth weight, and can increase the risk of low birth weight for the fetus, and hypertension for the mother. People are advised to quit smoking when they conceive.

A pregnant woman should not only stay away from smoking actively but passively as well. If a couple is trying to conceive, it is recommended that they avoid smoking and being in environments where people are smoking.

Education and counselling to increase awareness in women of harms of exposure and means to minimize them, along with counselling of husbands, partners or other tobacco smoking household members should be done actively.
