以前对电子烟对现实世界戒烟成功的影响的分析主要基于在美国和英国进行的调查,尼古丁电子烟可以很容易地获得。在澳大利亚,法规使获得含有尼古丁的电子烟变得困难。因此,在澳大利亚使用电子烟作为戒烟援助的有效性可能低于迄今为止公布的基于调查的估计。这项研究旨在评估使用电子烟戒烟尝试对澳大利亚过去一年戒烟成功的影响。
过去一年戒烟成功的多变量逻辑回归模型。
2019年澳大利亚国家药物战略家庭调查浪潮的受访者在调查前的12个月内进行了戒烟尝试。
在调查时,如果戒烟尝试导致禁欲超过一个月,则假定过去一年戒烟成功。
2019年,尝试使用电子烟戒烟的澳大利亚人比尝试不使用电子烟戒烟的吸烟者取得了更大的成功[调整后的优势比(aOR)=1.68;95%置信区间(CI)=1.09-2.60]。如果只尝试过一次或两次电子烟的人被认为没有使用过电子烟,估计效果稍强(aOR=1.98;95%CI=1.27-3.10)。此外,在从海外网站获取电子烟的vapers中,估计的比值比较高(aOR=2.24;95%CI=1.02-4.93).
与尝试戒烟的澳大利亚人相比,在2019年尝试戒烟的澳大利亚人中,使用电子烟的戒烟尝试似乎与更大的成功有关。在调整了混杂效应之后。
Previous analyses of the effect of e-cigarettes on real world smoking cessation success have mainly been based on surveys undertaken in the United States and United Kingdom, where nicotine e-cigarettes can be readily obtained. In Australia, regulations have made obtaining e-cigarettes containing nicotine difficult. The effectiveness of e-cigarette use as a smoking cessation aid in Australia might therefore be lower than survey-based estimates published to date. This study aimed to estimate the effect of using e-cigarettes for a smoking cessation attempt on past-year smoking cessation success in Australia.
Multivariable logistic regression models for past-year smoking cessation success.
Respondents to the 2019 wave of Australia\'s National Drug Strategy Household Survey who made a smoking cessation attempt in the 12 months leading up to the survey.
Past-year smoking cessation success was assumed if a smoking cessation attempt resulted in abstinence of more than a month at the time of the survey.
In 2019, Australians who attempted to quit smoking using e-cigarettes achieved greater success than smokers attempting to quit without e-cigarettes [adjusted odds ratio (aOR) = 1.68; 95% confidence interval (CI) = 1.09-2.60]. If people who only tried e-cigarettes once or twice are considered not to have used e-cigarettes, the estimated effect was slightly stronger (aOR = 1.98; 95% CI = 1.27-3.10). Also, the estimated odds ratio was higher among vapers who acquired their e-cigarettes from overseas websites (aOR = 2.24; 95% CI = 1.02-4.93).
Use of e-cigarettes for a smoking cessation attempt appears to be associated with greater success among Australians who attempted to quit tobacco in 2019 compared with Australians attempting to quit without e-cigarettes, after adjusting for confounding effects.
