Maternal tobacco use during pregnancy has been linked to a host of negative infant and child outcomes, including low birthweight, preterm birth, and various birth defects (1–5). The 2003 revision of the U.S. Standard Certificate of Live Birth included new and modified items on maternal cigarette smoking before and during pregnancy. The 2016 natality data file is the first for which this information is available for all states and the District of Columbia (D.C.). This report presents the prevalence of cigarette smoking at any time during pregnancy among women who gave birth in 2016 in the United States by state of residence as well as maternal race and Hispanic origin, age, and educational attainment.."
