Tobacco use is the single most preventable cause of poor birth outcomes. Smoking during pregnancy is associated with low birth weight,spontaneous abortion, placenta previa, and an increased risk of SIDS. Placental metabolism and transfer confer unique susceptibility to smoking and ETS exposure. This session will review placental toxicology and the maternal-fetal unit, biological monitoring of pregnant women,and the health policy and economics of smoking cessation programs.In addition,a specific examination of the effect of pregnancy on levels of biological markers from pregnant subjects will be discussed, drawn from a series of national surveys conducted by the CDC DEH (Third National Report on Human Exposure). The significance to researchers to determine the magnitude of the effect pregnancy has upon the interpretation of biological markers and the value of smoking cessation programs will be discussed for this vulnerable population.

Session Objectives: # Identify susceptibility of the maternal-fetal environment to toxic exposures from smoking/ETS on pregnancy and birth outcome; # Discuss the stability of biomarkers and contribution of tobacco smoke exposures in pregnant women; # Describe the benefits and motivation of smoking cessation programs in pregnancy; # Assess health policy and economics of smoking cessation programs for pregnant women
