Changes in smoking behavior between first and second pregnancies.
OBJECTIVE
To assess changes in maternal smoking behavior at the second pregnancy.


METHODS
First and second birth certificates were matched for 5241 white and black mothers in Kansas City, Mo, who had singleton births between 1994 and 2003.


RESULTS
The pregnancy-smoking quit rate was 24.9%, and the pregnancy-smoking initiation rate was 4.8%.


CONCLUSIONS
Twenty-five percent of women who smoked and 5% of women who did not smoke during their first pregnancy changed their behavior during their second pregnancy. These findings reflect a minimal net shift in pregnancy-smoking between pregnancies and support the importance of persistent antismoking socialization that is independent of a pregnant woman's previous pregnancy-smoking status.
