abstract: OBJECTIVE
  This report presents trend data for smoking during pregnancy. Data are presented for various characteristics including age of mother, race and ethnic origin, place of birth of mother, and State of residence.
  
  
  METHODS
  Descriptive tabulations were calculated using data reported on birth certificates between 1990 and 1996.
  
  
  RESULTS
  The rate of smoking during pregnancy has declined each year between 1990 and 1996. In 1996 over 400,000 women reported smoking during their pregnancies (13.6 percent of all births). The rates of smoking during pregnancy for women 15-19 years of age declined between 1990 and 1994 but increased in the last two years, and now they have the highest rates of all age groups. Among race and ethnic groups, American Indian, non-Hispanic white, and Hawaiian women had the highest rates of smoking during pregnancy in 1996, while Chinese women had the lowest rates.
