Some, but not all, studies suggest that menthol cigarette smokers have more difficulty quitting than non-menthol cigarette smokers. Inconsistent findings may be a result of differences in smoker characteristics (eg, daily vs. non-daily smokers) across studies. This study examines the relationship between menthol cigarette use, cessation, and relapse in a longitudinal, nationally representative study of tobacco use in the United States.
Data come from four waves of the Population Assessment of Tobacco and Health Study. Waves 1-4 were conducted approximately annually from September 2013 to January 2018. Generalized estimating equation models were used to prospectively examine the relationship between menthol cigarette use, cessation, and relapse in non-daily and daily adult (18+) smokers. Cessation was defined as smokers who had not used cigarettes within the past 30 days at their subsequent assessment. Relapse was defined as cessation followed by past 30-day smoking in the next assessment.
Among daily smokers (n = 13 710), 4.0% and 5.3% of menthol and non-menthol smokers quit after 1 year, respectively. In an adjusted model, menthol smokers were less likely to quit compared with non-menthol smokers (odds ratio [OR] = 0.76 [0.63, 0.91]). When the sample was stratified by race/ethnicity, African American (OR = 0.47 [0.24, 0.91]) and White (OR = 0.78 [0.63, 0.97]) daily menthol users were less likely to have quit. Among non-daily smokers (n = 3608), there were no significant differences in quit rates. Among daily and non-daily former smokers, there were also no differences in relapse rates between menthol and non-menthol smokers.
Menthol cigarette use is associated with lower odds of cessation.
Findings from this study suggest that menthol cigarette use is associated with lower odds of cessation, but not relapse. Removing menthol cigarettes from the market may improve cessation rates.
一些,但不是全部,研究表明薄荷醇香烟吸烟者比非薄荷醇香烟吸烟者戒烟更困难。研究结果不一致可能是由于研究中吸烟者特征(例如,每日吸烟者与非每日吸烟者)的差异所致。本研究在美国一项关于烟草使用的纵向、全国代表性研究中,研究了薄荷醇香烟使用、戒烟和复吸之间的关系。
数据来自四次“人口烟草与健康评估研究”。第一至第四波调查于 2013 年 9 月至 2018 年 1 月期间每年进行一次。广义估计方程模型用于前瞻性研究非每日吸烟者和每日吸烟者(18 岁及以上)中薄荷醇香烟使用、戒烟和复吸之间的关系。戒烟定义为在随后的评估中过去 30 天内未使用香烟的吸烟者。复吸定义为在随后的评估中戒烟后过去 30 天内吸烟。
在每日吸烟者中(n = 13710),薄荷醇和非薄荷醇吸烟者分别有 4.0%和 5.3%在 1 年内戒烟。在调整后的模型中,与非薄荷醇吸烟者相比,薄荷醇吸烟者戒烟的可能性较低(比值比 [OR] = 0.76 [0.63, 0.91])。当按种族/族裔进行分层时,非裔美国人和白人(OR = 0.47 [0.24, 0.91])和白人(OR = 0.78 [0.63, 0.97])每日薄荷醇使用者戒烟的可能性较低。在非每日吸烟者中(n = 3608),戒烟率没有显著差异。在每日和非每日前吸烟者中,薄荷醇和非薄荷醇吸烟者的复吸率也没有差异。
薄荷醇香烟使用与戒烟几率降低相关。
本研究结果表明,薄荷醇香烟使用与戒烟几率降低相关,但与复吸无关。从市场上移除薄荷醇香烟可能会提高戒烟率。
