Home smoking bans significantly reduce secondhand smoke exposure among children, but parents may offer discordant reports on whether there is a home smoking ban. The purpose of this study was to examine national trends in (a) parental discordance/concordance in the reporting of home smoking bans and (b) correlates of discordant/concordant reports among two-parent households with underage children from 1995 to 2007.


Data from the 1995/1996, 1998/1999, 2001/2002, 2003, and 2006/2007 Tobacco Use Supplement of the U.S. Current Population Survey were used to estimate prevalence rates and multinomial logistic regression models of discordant/concordant parental smoking ban reports by survey period.


Overall, the percentage of households in which the 2 parents gave discordant reports on a complete home smoking ban decreased significantly from 12.7% to 2.8% from 1995 to 2007 (p < .001). Compared with households where both parents reported a complete smoking ban, discordant reports were more likely to be obtained from households with current smokers (p < .01) across survey periods. Compared with households where both parents reported the lack of a complete home smoking ban, discordant reports were more likely among households with college graduates, no current smokers, and parents with Hispanic ethnicity (p < .05).


Parental concordance on the existence of a home smoking ban increased from 1995 to 2007. This suggests estimates of home smoking bans based on just one parent may be more reliable now than they were in the past. Interventions to improve the adoption and enforcement of home smoking bans should target households with current smoker parents.
