Background: Some previous studies have claimed that electronic cigarette (e-cigarette) use is helpful in quitting smoking. However, this role of e-cigarettes remains uncertain because several current smokers use e-cigarettes as an alternative to tobacco smoking. The present study aimed to compare the quitting behaviors of dual users and cigarette-only smokers.
Methods: Data of 5,179 current smokers from the sixth and seventh Korea National Health and Nutrition Examination Surveys (2013?2017) were analyzed. Current smokers were divided into dual users and cigarette-only smokers based on e-cigarette use in the past month. Factors influencing e-cigarette use were investigated. Differences in the quitting behaviors between both groups were assessed using multivariate logistic regression analysis with STATA 11.0.
Results: Young age (<40 years) and smoking amount (>20 cigarettes/day) were associated with e-cigarette use. Nicotine replacement therapy (NRT) use in the past 5 days was associated with e-cigarette use [odds ratio (OR), 5.328; 95% confidence interval (CI), 2.377?11.941]. Dual users demonstrated higher quit attempts in the past year (OR, 1.600; 95% CI, 1.113?2.301). There was no difference between dual users and cigarette-only smokers in choosing an evidence-based quit method such as using a quit line or visiting a smoking cessation clinic. However, dual use was associated with use of NRT over the counter NRT use.
Conclusion: There are no differences in employing an evidence-based smoking cessation method between dual users and cigarette-only smokers, despite the higher quit attempts in dual users. Further evaluation of the effect of NRT use as a quitting method on dual users is warranted.
