Final adult multivariate model results showing adjusted odds ratios* associated with strength of local restaurant smoking regulations† and all control variables for having a perception of lower adult smoking prevalence in one’s town,‡ for perceiving smoking in restaurants or bars in one’s town as unacceptable,§ and for perceiving that other adults in one’s town view smoking in restaurants as socially unacceptable¶

| Adjusted odds ratios* (95% CI) for having a lower perception of adult smoking prevalence in one’s town‡ | Adjusted odds ratios* (95% CI) for perceiving smoking in restaurants as unacceptable (based on individual opinion)§ | Adjusted odds ratios* (95% CI) for perceiving smoking in bars as unacceptable (based on individual opinion)§ | Adjusted odds ratios* (95% CI) for perceiving adults in one’s town as viewing smoking in restaurants as socially unacceptable§ | |
| *Adjusted odds ratio reflects final model that included only those variables that contributed significantly to the model, as assessed by a Wald test (with α = 0.10). Odds ratios are derived from a GEE logit model that accounts for clustering among subjects living in the same town. Odds ratios are adjusted for all other variables included in the model. | ||||
| †Strength of local restaurant smoking regulation was defined as strong if it banned smoking completely in all restaurants with no variances, medium if it banned smoking but allowed variances or restricted smoking to enclosed, separately ventilated areas, and weak if it required only designated smoking areas or did not restrict smoking at all. | ||||
| ‡Having a lower perception of adult smoking prevalence in one’s town was defined as responding that “very few” or “less than half” of adults in one’s town smoke (compared to “about half”, “more than half”, or “almost all”). | ||||
| §For personal acceptability of smoking in restaurants or bars, viewing smoking as personally unacceptable was defined as respondents stating that they think smoking should not be allowed at all (compared to being allowed anywhere or only in special sections). For perceived social acceptability of smoking in restaurants, viewing smoking as socially unacceptable was defined as respondents stating that they think adults in their town “disapprove a lot” of smoking in restaurants (compared to “disapprove a little” or “don’t mind”). | ||||
