Smoking During Pregnancy in the 1990s
This paper presents trends and variations in smoking during pregnancy in the United States. Data are presented for various characteristics including mother's age, race, ethnic origin, place of birth and State of residence, live birth order, and birth weight. The percentage of women who smoked during pregnancy declined every year from 1990 through 1999. In 1999, 12.3 percent of women giving birth reported smoking during pregnancy. For women 15 to 19 years of age, the rate of smoking during pregnancy declined between 1990 and 1994 but has increased since then and teenagers now have the highest rate of all age groups.
