Background: Previous some literature had a claim that electronic cigarette (e-cigarette) use is helpful to quit smoking. However, the role of e-cigarette has been suspected because many current smokers tend to use the e-cigarette as alternative tobacco. The aim of this study is to compare quitting behaviors of dual users and cigarette-only smokers.
Method: Data of 5,179 current smokers from sixth and seventh Korea National Health and Nutrition Examination Survey (2013-2017) were analyzed in this study. Current smokers were divided into dual users & cigarette-only smokers by e-cigarette use within 1month. Factors influencing electronic cigarette use were investigated. Quitting behaviors between dual users and cigarette-only users were assessed using multivariate logistic regression analysis. STATA 11.0 (Stata corp.) were used.
Results: Young age group (<40years) and smoking amount (over 20cigarette/day) were associated with e-cigarette use. Nicotine replacement therapy (NRT) use within 5days was associating factor of e-cigarette use (OR 5.328, 95% confidence interval (CI): 2.377-11.941). Dual users had more experience of quit attempt in last 1year (OR 1.600, 95% CI 1.113-2.301). There is no difference between dual users and cigarette-only smokers in choosing evidence-based quit method such as Quit-line or smoking cessation clinic. However, dual use had associated with the use of NRT from the pharmacy.
Conclusion: There are no difference in use of evidence-based quit method between dual users and cigarette-only smoker despite of more quit attempts in dual users. Further evaluation on effect of NRT use of dual users as a quit method is necessary.
