Disparities in secondhand smoke exposure among children and adults in the U.S.: 1998-2000 and 2005-2010
Methods: 39,509 children and 91,561 nonsmoking adults from the 1998, 2000, 2005 and 2010 National Health Interview Survey Cancer Control Supplements were included. Multivariate logistic regression analysis was used to determine the factors associated with SHS exposure.
Results: The prevalence of SHS exposure declined from 25.3% in 1998-2000 to 10.0% in 2005-2010 for children and from 11.4% in 1998-2000 to 4.5% in 2005-2010 for adults. By race/ethnicity, Non-Hispanic Black and non-Hispanic Other children were less likely to be exposed to SHS in 1998-2000 while non-Hispanic Asian adults were less likely to be exposed to SHS in 2005-2010. For both children and adults, the lowest education group was more likely to be exposed to SHS in 1998-2000 but not in 2005-2010. For income, children in households with higher income had decreased odds of being exposed to SHS in 1998-2000 but increased odds in 2005-2010. Adults with high income were less likely to be exposed to SHS during 1998-2000 but not 2005-2010. Disparities for children living in the Midwest and South existed in 2005-2010 but not in 1998-2000.
Conclusions: Sociodemographic disparities in SHS exposure have changed for children and adults over time. Tobacco control policies that target those groups with particularly high exposure are needed.

Learning Objectives:
Assess and compare sociodemographic disparities in secondhand smoke exposure at home among children (0-17) and nonsmoking adults (18+) in the U.S. during two time periods: 1998-2000 and 2005-2010.
Demonstrate the importance of implementing tobacco control policies that reduce secondhand smoke exposure and target those groups with particularly high exposure.

Qualified on the content I am responsible for because: I have been working in the field of tobacco control for more than eight years. My research focuses on the economic impact of tobacco on health and healthcare expenditures. My current studies include estimating the economic costs of secondhand smoke exposure in U.S.. I am also interested in the smoking behaviors among California Asians.
