The involvement of health-care professionals in tobacco-control activities is essential to prevent smoking-related morbidity and mortality. The purposes of this predictive correlational study were to examine tobacco-control activities and to identify the predictors of such activities of community health practitioners (CHPs). Of the 1,813 members of the Korean Association of CHP, 1,247 participated in this study. A mailed survey was conducted to collect data.The majority of CHPs supported tobacco-control policies and recognized tobacco-control activities as an important role for them. Only 44.3% of CHPs were confident in their knowledge and skills regarding tobacco-control activities, and only 30.8% had received professional tobacco-control education. While the majority of the CHPs “asked, advised, and assessed” their clients, only a small number “assisted or arranged”. The tobacco-control activities of CHPs were predicted by their attitude toward it, age, experience of tobacco-control education, educational level, and general perception of the risk of smoking; these variables accounted 13.5% of variance in the tobacco-control activities of CHPs.These findings provide the basis for developing a continuing education program for CHPs. CHPs should be encouraged to integrate tobacco-control activities into their routine practice, and CHP education programs should be adjusted to increase the time spent on the tobacco-control intervention techniques.
