"Home Smoking Bans Among U.S. Households with Children and Smokers"
Background: Public health campaigns have reduced the exposure of U.S. children to secondhand
smoke at home; however, these may not have been equally effective across subgroups.
Purpose: To examine prevalence of home smoking bans among U.S. households with both children
and smokers, over time and by demographic subgroups.
Methods: The Tobacco Use Supplement to the Current Population Survey (TUS-CPS) is a nationally
representative household survey of tobacco use. The 1992/1993 and 2006/2007 TUS-CPS interviewed
22,746 households from a major racial/ethnic group with both children and adult smokers.
Predictors of complete home smoking bans among demographic subgroups were identif?ed using
multivariate logistic regression. Analyses were conducted in 2010–2011.
Results: Complete home smoking bans among U.S. households with children and smokers (smoking
families) more than tripled, from 14.1% in 1992/1993 to 50.0% in 2006/2007. However, non-
Hispanic white and African-American smoking families lagged behind Asian/Pacif?c Islanders and
Hispanics. In 2006/2007, 67.2% of African-American smoking families allowed smoking in the
home, as did 59.2% of smoking families with all children aged 14 years. Bans were more likely
among more-educated households and in states with lower adult smoking prevalence; however, these
differences were attenuated in some racial/ethnic groups.
Conclusions: As of 2006/2007, only half of U.S. households with both children and smokers had
complete home smoking bans. Home bans were less common among smoking families with older
children, in African-American households, and in Hispanic or non-Hispanic white households in
states with high smoking prevalence. Interventions are needed to promote smokefree homes among
these groups.
"Association Between Smokefree Laws and Voluntary Smokefree-Home Rules"
Background: More states and localities are passing restrictions on smoking in public places and
workplaces.
Purpose: To determine what, if any, association exists between enactment of strong laws making
public places or workplaces smokefree on adoption of voluntary smokefree-home policies, particularly
whether such laws are associated with increased smoking at home.
Methods: Logistic regressions were used to estimate the OR of a person living with a 100%
smokefree-home rule as a function of individual characteristics, household composition, and
whether or not the residential region is covered by clean indoor air laws. The data came from
successive waves of the Tobacco Use Supplement to Current Population Survey (TUS-CPS) for the
years 1992–2007, and the American Nonsmokers’ Rights Foundation database of state and local
government clean indoor air laws. Analysis was conducted in 2010 and 2011.
Results: Living in a county fully covered by a 100% clean indoor air law in workplaces or restaurants
or bars is associated with an increased likelihood of having a voluntary 100% smokefree-home rule
both for people living with smokers (OR7.76, 95% CI5.27, 11.43) and not living with smokers
(OR4.12, 95% CI3.28, 5.16).
Conclusions: Strong clean indoor air laws are associated with large increases in voluntary
smokefree-home policies both in the homes with and without smokers. These results support the
hypothesis of norm spreading of clean indoor air laws.
