A new NCHS report presents findings on maternal smoking prevalence and cessation before and during pregnancy as collected on the 2003 U.S. Standard Certificate of Live Birth, for a 46-state and District of Columbia reporting area, representing 95% of all births in the United States.
Findings:
- About 1 in 10 women who gave birth in 2014 smoked during the 3 months before pregnancy (10.9%), and about one-quarter of these women (24.2%) did not smoke during pregnancy (i.e., quit before pregnancy).
- The smoking rate at any time during pregnancy was 8.4%, with 20.6% of women who smoked in the first or second trimesters quitting by the third trimester.
- Smoking during pregnancy was more prevalent for women aged 20–24 (13.0%) than for other ages, and by race and Hispanic origin, the highest rate was for non-Hispanic American Indian or Alaska Native women (18%).
