However, when it comes to households with current or former smokers, it is still recommended to take into account both parents�� responses because our study indicates they are significantly more likely to provide discordant reports on their www.selleckchem.com/products/brefeldin-a.html home smoking ban status. Limitations This study is subject to several limitations. First, there were minor changes in the wording of the TUS-CPS home smoking ban question after 2002. While some people would interpret ��in your home�� and ��inside your home�� as equivalent expressions, the latter has more emphasis on the indoor environment. On the other hand, the newer version of the question asks about rules that apply not only to home residents but also visitors and workmen, thus making the definition of home smoking bans more restrictive.

This suggests that our estimates of actual prevalence of a complete home smoking ban for the 2003 and 2006�C2007 periods may have been affected in opposite directions by these changes in the wording of the question, and the magnitude and direction of the net effect is difficult to tell. In addition, the CPS recoded its race/ethnicity question. Starting in 2003, respondents were able to select more than one race. This change may affect our estimates regarding the association between race/ethnicity and home smoking ban reports. Unfortunately, the direction of this potential bias is unknown. Second, a subset of the 2003 TUS-CPS data was longitudinal with respect to the 2001�C2002 data (i.e., about one-third of respondents to the 2003 TUS-CPS had participated in the 2001�C2002 survey round).

There was a marked increase in the prevalence of a complete home smoking ban between 2001 and 2002 and 2003, considering the relatively shorter interval between the two surveys. It is possible this sharper increase was due in part to learning effects associated with previous participation in TUS-CPS. Hence, the results for that survey period may overestimate the real prevalence of home smoking bans and concordant parental reports in 2003. However, even excluding that survey period, the results suggest a clear trend toward decreasing rates of discordant parental reports and increasing rates of concordant complete home smoking ban reports over the period examined. In conclusion, this study suggests increasing concordance of parental reports on home smoking bans and underscores Dacomitinib the need to focus future interventions on households with current smokers to reduce SHS and THS exposure and protect the health of children in these households.
