背景和目标：加拿大安大略省自2017年1月1日起禁止使用薄荷味烟草产品。这项研究旨在评估薄荷醇禁令对吸烟行为的两年内的长期影响，这是未知的。方法：2016年9月至12月进行了人群队列研究和基线调查(n=1821)，并在薄荷醇禁令之前对安大略省现有吸烟者(16+)进行了2019年1月至8月的跟踪调查。泊松回归被用来评估禁烟前薄荷醇状态的戒烟概率，控制了吸烟和人口统计学特征的差异，并使用多重归因来处理缺失的数据。结果：在薄荷醇禁令后的两年里，薄荷醇吸烟者报告已经戒烟的可能性更大(12%[每日薄荷醇]和10%[偶尔薄荷醇]对3%[非薄荷醇]；p<；.001)。在调整了吸烟和人口统计学特征后，每天吸食薄荷醇的人戒烟的可能性更高(调整后的相对风险[ARR]2.08；95%可信区间[CI]1.20-3.61)，并报告了更多的戒烟尝试(ARR1.45；95%可信区间1.15-1.82)。在试图戒烟的人中，薄荷醇吸烟与复发无关(每日ARR=0.96；95%可信区间：0.86，1.07；偶尔吸烟ARR=0.99；95%可信区间：0.90，1.08)。然而，在禁令实施一年后报告使用其他口味烟草产品的薄荷醇使用者之间存在统计上显著的交互作用(ARR=0.26[95%CI：0.08，0.90])。结论：研究发现，在安大略省薄荷醇禁令实施两年后，每天吸薄荷醇的人戒烟的可能性增加，每天和偶尔吸薄荷醇的人戒烟的尝试比不吸薄荷醇的人更多。
Background and Aims: The province of Ontario, Canada, banned the use of menthol-flavored tobacco products as of January 1, 2017. This study aims to assess the longer-term impact of a menthol ban on smoking behavior at 2 years, which is unknown.Methods: Population cohort study with baseline survey (n = 1821) conducted September-December 2016 and follow-up survey January-August 2019 among current smokers in Ontario (16+) prior to the menthol ban. Poisson regression was used to assess the probability of quitting smoking by pre-ban menthol status, controlling for differences in smoking and demographic characteristics, with multiple imputations used to address missing data.Findings: Menthol smokers were more likely to report having quit smoking (12% [daily menthol] and 10% [occasional menthol] vs. 3% [non-menthol]; p < .001) than non-menthol smokers in the 2 years after a menthol ban. After adjustment for smoking and demographic characteristics, daily menthol smokers had higher likelihood of quitting smoking (adjusted relative risk [ARR] 2.08; 95% confidence interval [CI] 1.20-3.61) and reported more quit attempts (ARR 1.45; 95% CI 1.15-1.82). Among those who attempted to quit, menthol smoking was not associated with relapse (daily ARR = 0.96; 95% CI: 0.86, 1.07; occasional ARR = 0.99; 95% CI: 0.90, 1.08). However, there was a statistically significant interaction among menthol users who reported using other flavored tobacco products 1 year after the ban (ARR = 0.26 [95% CI: 0.08, 0.90])Conclusions: The study found increased probability of quitting among daily menthol smokers and more quit attempts among daily and occasional menthol smokers compared with non-menthol smokers in Ontario 2 years after the implementation of a menthol ban.
