Smoking during pregnancy is an established risk factor for adverse pregnancy outcomes and health issues for newborns later in life (1-3). National birth certificate data on cigarette smoking and the number of cigarettes smoked before and during pregnancy first became available in 2016. These data allow for the analysis of maternal cigarette use during pregnancy by numerous maternal and infant characteristics. This report describes changes in the number and percentage of mothers who smoked cigarettes at any time during pregnancy in the United States from 2016 to 2021 and changes between 2016 and 2021 in the percentage of mothers who smoked during pregnancy by maternal age, race and Hispanic origin, and state of residence.
孕期吸烟是导致不良妊娠结局以及新生儿日后出现健康问题的一个已确定的风险因素(1 - 3)。关于孕期吸烟及孕期前后吸烟数量的全国出生证明数据于2016年首次可得。这些数据有助于按众多母婴特征分析孕期母亲的吸烟情况。本报告描述了2016年至2021年期间美国孕期任何时候吸烟的母亲数量及百分比的变化，以及2016年至2021年期间按母亲年龄、种族和西班牙裔血统以及居住州划分的孕期吸烟母亲百分比的变化。
