Data Brief No. 126. Environmental Tobacco Smoke Exposure in Children Aged 3‒19 Years With and Without Asthma in the United States, 1999‒2010Environmental tobacco smoke (ETS) has harmful effects on children's respiratory health and has been linked to higher risk of middle ear infections, bronchitis and pneumonia, coughing and wheezing, worse lung function, and asthma development. Children with asthma whose parents smoke have more severe symptoms and more frequent exacerbations. National asthma guidelines recommend ETS exposure be minimized among persons with asthma. ETS exposure in children with and without asthma has not been directly compared in a national sample of the U.S. population. This report presents trends in ETS exposure in children with and without asthma from 1999 to 2010, and describes differences by sex, race and ethnicity, income, and age group in 2007–2010.
