Maternal & Child Health Data

Tobacco During Pregnancy, 2018

Definition: Used tobacco during pregnancy gives the percentage of mothers who used tobacco during pregnancy in 2018. All reporting areas, except California, routinely collect information on maternal tobacco use, but the information collected with the 2003 revision of the birth certificate is not comparable to the information collected with earlier versions of the birth certificate. Thus, maternal tobacco use data are recoded based on the birth certificate version used by the mother’s place of residence in the year of birth. These percentages exclude births where tobacco use is categorized as “not stated” or “not reported” from the total number of births (i.e., the denominator).
