Smoke-filled rooms: smoking in children's homes and state smokefree air legislation

The purpose of this work is to assess in-home secondhand smoke (SHS) exposure among U.S. children and examine associations with state smokefree air laws. Methods: Using 2007 National Survey of Children’s Health data (n=91,970) and state-level smoking and legislation ratings, we estimated prevalence and conducted logistic regression for children living with smokers. Results: 26.2% of children live with smokers; 7.6% are exposed to SHS at home. Smokefree homes are more common among Hispanic families and those with young children, but less likely in low-income or single-parent households. Stronger state laws correlate with higher smokefree home prevalence.
