Tobacco Use
Tobacco use during pregnancy is the most important modifiable risk factor associated with adverse pregnancy outcomes. Research has shown that smoking during pregnancy causes many health problems for both mothers and babies, such as infertility, placental rupture, abnormal placental implantation, preterm premature rupture of membrane (PPROM) or early rupture of the amniotic sac membrane, premature birth, stillbirth, low-birth-weight infant, and sudden infant death syndrome (SIDS).
