Media and secondhand smoke exposure: results from a national survey.

Objectives: To investigate whether associations between anti-secondhand smoke (SHS) media, social cognitions about SHS, and home restrictions on smoking follow patterns observed in smoking behavior.

Methods: Based on a nationally representative sample of 2348 US adults drawn from the American Legacy Foundation's American Smoking and Health Survey, we tested relationships among scales of anti-SHS media, social cognitions, and home restrictions.

Results: We found anti-SHS media and SHS cognitions, as well as social cognitions and home restrictions, to be significantly associated. Social cognitions mediated the relationship between anti-SHS media and home restrictions.

Conclusions: Previously observed relationships between media, social cognitions, and smoking also exist for SHS. Anti-SHS media campaigns to increase home restrictions may help to reduce SHS exposure.
