Women who smoked during their first trimester of pregnancy had a 20% higher risk of having a child with a heart defect than those who did not smoke, according to a study presented at the Pediatric Academic Societies meeting. Smoking more than 20 cigarettes each day early in pregnancy was associated with a 1.6 times greater heart defect risk, while smoking one to 10 cigarettes was tied to a 1.15 times higher risk, compared to nonsmokers.
