Association between electronic cigarette use and smoking cessation in the European Union in 2017: analysis of a representative sample of 13 057 Europeans from 28 countries
Menée en 2017 par enquête auprès de 13 057 citoyens européens âgés d'au moins 15 ans, cette étude analyse l'association entre une utilisation de la cigarette électronique et le sevrage tabagique, en fonction de la fréquence d'utilisation
Objectives: To examine the association between electronic cigarette (e-cigarette) use and smoking cessation in the European Union (EU) in 2017 according to e-cigarette use frequency and smoking cessation duration. Design: Cross-sectional survey of EU citizens, representative of the population (Special Eurobarometer 458). Weighted proportions (95% CI) and adjusted prevalence ratios (aPRs) were calculated. Setting: EU. Participants: 13 057 EU citizens aged ≥15 years (6904 current and 6153 former smokers). Results: Current daily e-cigarette use was reported by 2.4% (1.8%–3.1%) of current and 3.3% (2.5%–4.2%) of former smokers (p=0.002), while former daily use was reported by 5.6% (4.7%–6.8%) and 1.9% (1.3%–2.7%), respectively (p<0.001). More than half of all former smokers had quit for >10 years. Current daily e-cigarette use was rare among former smokers of >10 years (0.2%, 0.1%–0.6%) and was more prevalent in former smokers of ≤2 and 3–5 years (12.9%, 9.1%–17.9% and 9.0%, 5.8%–13.7%, respectively). Compared with never use, current daily e-cigarette use was associated with being a former smoker of ≤2 (aPR 4.96, 95% CI 3.57 to 6.90) and 3–5 years (aPR 3.20, 95% CI 2.10 to 4.87). Former daily e-cigarette use was associated with being a former smoker of ≤2 years (aPR 1.96, 95% CI 1.21 to 3.12). Current daily e-cigarette use was negatively associated with being a former smoker of 5–10 and >10 years. Conclusions: Current daily e-cigarette use in the EU in 2017 was rare among former smokers of >10 years and was positively associated with recent (≤5 years) smoking cessation. Former daily e-cigarette use was also positively associated with recent (≤2 years) smoking cessation.
