Context: Despite known adverse health effects, many women continue to smoke during pregnancy. Public attention has now focused on the economic as well as health effects of this behavior. Objective: To estimate health care costs associated with smoking-attributable cases of placenta previa, abruptio placenta, ectopic pregnancy, preterm premature rupture of the membrane (PPROM), pre-eclampsia, and spontaneous abortion. Design: Pooled odds ratios were used with data on total cases to estimate smoking-attributable cases.
