The relationship between home smoking bans and exposure to state tobacco control efforts and smoking behaviors

To examine the relationship between home smoking bans and adult smokers' exposure to the statewide California Tobacco Control Program (TCP) and their cigarette smoking behavior.

Cross-sectional survey that was part of the statewide Independent Evaluation of the California Tobacco Control, Prevention and Education Program.

Random telephone interviews within 18 California counties.

A representative sample of 1315 adult smokers, aged 25 years and older.

The telephone survey included questions about smoking behavior, quitting smoking, exposure to tobacco control program components, home smoking rules, and attitudes related to tobacco use and environmental tobacco smoke (ETS).

Smokers with a home smoking ban were twice as likely (OR = 2.29; 95% CI 1.22, 4.29) to have heard of TCP community programs and three times more likely (OR = 3.18; 95% CI 1.34, 7.57) to have seen and talked about the ETS media spot than smokers with no home smoking policy. Multivariate regression models indicated that having a home smoking ban was related to smoking fewer cigarettes per day and greater interest in quitting smoking compared with smokers with no smoking rules in the home (p < .05).

These findings suggest that smokers reporting exposure to the California TCP were more likely to have restrictive home smoking policies and that more restrictive home smoking policies were associated with reduced smoking behavior.
