Frequency of E-cigarette use and cigarette smoking among Canadian students
Menée à l'aide d'une enquête canadienne réalisée en 2016-2017 auprès de 51 661 paticipants, cette étude analyse l'association entre la fréquence d'utilisation de la cigarette électronique et le tabagisme chez les adolescents âgés d'au moins 15 ans
The emergence of electronic nicotine delivery systems (commonly referred to as e-cigarette) has created an ongoing public health debate and concerns, especially among 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.
