 Abstract
Introduction: Few studies were performed for electronic cigarette (e-cigarette) use among Korean adults with no history of combustible cigarette use.
Methods: We used data from the Korea Community Health Survey (2014-2017). We analyzed factors associated with e-cigarette ever use among persons with no history of combustible cigarette use. Multivariated logistic regression analysis was used to evaluate the relationship between ever use of e-cigarettes after adjusting sociodemographic and health behavior factors among never users of combustible cigarettes (CC).
Results: Among the 579,815 participants of never CC users, 971 (0.2%) have ever used e-cigarette. The odds ratios (ORs) of ever use of e-cigarettes were higher in younger age (OR of aged 19-34 was 9.53 compared to aged 돟 65, 95% Confidence Interval (CI) 4.11-22.12), heavy drinkers (OR 1.94, 95% CI 1.54-2.46), persons with depressive symptoms (OR 2.36, 95% CI 1.62-3.44), poor general health (OR 1.39, 95% CI 1.10-1.75), diabetes group (OR 2.27, 95% CI 1.36-3.80). However, the ORs of ever use of e-cigarettes were lower in female (OR 0.11, 95% CI 0.08-0.14), low physical activity group (OR 0.73, 95% CI 0.56-0.95), hypertension group (OR 0.59, 95% CI 0.39-0.89).
Conclusion: Ever use of e-cigarette was not common among never users of CC. Prevalence of ever e-cigarette use among never CC users was more prevalent among younger age group, male, persons with poor health and poor health habits. This should be considered to make tobacco control policy.
