Abstract
This study compared characteristics of Korean American men in two studies: a telephone survey with a random sample of Korean American men who reported daily smoking versus a smoking cessation clinical trial with a convenience sample of Korean American men who reported smoking at least 10 cigarettes a day. Guided by the Theory of Planned Behavior (TPB), both studies attempted to explain how much its theoretical variables (attitudes, perceived social norms, and self-efficacy) would explain quit intentions in Korean American men. Participants in the cessation study were less likely to have health insurance coverage (χ2 [2, 271] = 138.31, p = 0.001) than those in the survey study. The cessation group was more likely to smoke in indoor offices (χ2 [1, 231] = 18.09, p = 0.003) and had higher nicotine dependence than the survey group (t269 = 3.32, p = 0.001) but these differences became insignificant when only those who smoked 10 or more cigarettes were compared. Participants in the cessation study had more positive attitudes towards quitting (t267 = 4.99, p t269 = 5.63, p t268 = 9.86, p
Highlights
Korean American men are more likely to be current smokers than the general US male population, whereas Korean American women smoke at a rate similar to that of the general US female population [1,2]
It was reported that 71% of Korean American men die from smoking-related cancer deaths versus 30% of the general US population [3,4]
24% of Korean American smokers in California had ever been advised to quit by a physician as opposed to 46% for the general population of smokers in the same state [5,6]
Summary
Korean American men are more likely to be current smokers than the general US male population, whereas Korean American women smoke at a rate similar to that of the general US female population [1,2]. It was reported that 71% of Korean American men die from smoking-related cancer deaths versus 30% of the general US population [3,4]. It has been argued that participants in a clinical trial of smoking cessation differ from the general population of smokers, which is often addressed as a major limitation of the study. It is largely unknown how the two groups differ from each other. We examined how a convenience sample of Korean American men who participated in a cessation clinical trial [8] would differ from a random sample of Korean American men in a telephone survey study (unpublished data)
