The emergence of electronic nicotine delivery systems (commonly referred to as e-cigarettes) has created an ongoing public health debate and concerns, especially in regards to adolescents. The present study examined associations between the frequency of e-cigarette use and cigarette smoking among school students. Data on students (grades 7-12) was obtained from the 2016-2017 Canadian Student Tobacco, Alcohol and Drugs Survey (n = 51,661). Multivariable logistic regression analyses were conducted to examine associations between the frequency of e-cigarette use and smoking. Subgroup analyses were performed for male and female students. Among those who reported any cigarette smoking in the past 30 days, 55% reported e-cigarette use at least once in the last 30 days. Additionally, 17% reported e-cigarette use for 21-30 days among those who smoked cigarettes for at least 21 days. Multivariable logistic regression analysis showed e-cigarette use was associated with higher odds of cigarette smoking, especially among more frequent e-cigarette users. Those who used an e-cigarette 21-30 days had higher odds of cigarette smoking (smoked cigarette at least once AOR = 4.83, CI = 3.33-7.01; at least 11 days AOR = 3.73, CI = 2.40-5.80; at least 21 days AOR = 3.39, CI = 2.16-5.34). Findings suggest that those who smoked cigarettes at least once in the past 30 days had a higher frequency of e-cigarette use.
电子尼古丁传送系统（通常称为电子烟）的出现引发了一场持续不断的公共卫生辩论和担忧，尤其是在青少年方面。本研究调查了在校学生中电子烟使用频率与吸烟之间的关联。学生（7至12年级）的数据来自2016 - 2017年加拿大学生烟草、酒精和药物调查（n = 51,661）。进行了多变量逻辑回归分析以研究电子烟使用频率与吸烟之间的关联。对男女生进行了亚组分析。在过去30天内报告有吸烟的人群中，55%报告在过去30天内至少使用过一次电子烟。此外，在吸烟至少21天的人群中，17%报告电子烟使用时间为21至30天。多变量逻辑回归分析表明，使用电子烟与吸烟几率较高相关，尤其是在更频繁使用电子烟的人群中。使用电子烟21至30天的人群吸烟几率更高（至少吸过一次烟，调整后比值比[AOR]=4.83，置信区间[CI]=3.33 - 7.01；至少11天，AOR = 3.73，CI = 2.40 - 5.80；至少21天，AOR = 3.39，CI = 2.16 - 5.34）。研究结果表明，在过去30天内至少吸过一次烟的人群电子烟使用频率更高。
