The prevalence of smoking is greater and smoking restrictions are less common in rural areas in comparison to urban areas. Consequently, rural smokers and their families are at increased risk for adverse health consequences from smoking. The presence of home smoking restrictions (i.e., limiting or banning cigarette smoking in the home) can be a mediator for smoking cessation and can reduce health risks for those who live with smokers. The purpose of the present study was to identify correlates of home smoking restrictions among rural smokers. We surveyed 472 smokers from 40 rural Kansas primary care practices who were enrolled in a smoking cessation intervention study. We assessed the prevalence of home smoking restrictions and examined the relationship between such restrictions, demographic variables, comorbid diagnoses, and psychosocial measures of smoking abstinence self-efficacy and motivation to quit. Complete home smoking restrictions were found among 25.4% of rural smokers with an additional 28.3% reporting some restrictions. Restrictions were associated with younger age, higher controlled motivation to quit (i.e., motivation from external pressure), the presence of children under age 6 years living in the home, fewer friends who smoke, and a partner who does not smoke. Smokers with a comorbid diagnosis of high cholesterol, chronic lung disease, or heart disease were less likely to have restrictions. Most smokers in rural primary care practices do not have home smoking restrictions, particularly those without children or a nonsmoking partner and those with significant risk factors for smoking-related illnesses. These patients may be critical targets for broaching issues of home smoking restrictions.
