This study retrospectively describes smoking cessation aids, cessation services, and other types of assistance used by current and ex-smokers at their last quit attempt in four high-income countries.
Data are from the Wave 3 (2020) International Tobacco Control Four Country Smoking and Vaping Survey in Australia, Canada, England, and the United States (US). Eligible respondents were daily smokers or past-daily recent ex-smokers who made a quit attempt/quit smoking in the last 24-months, resulting in 3614 respondents. Self-reported quit aids/assistance included: nicotine vaping products (NVPs), nicotine replacement therapy (NRT), other pharmacological therapies (OPT: varenicline/bupropion/cytisine), tobacco (noncombustible: heated tobacco product/smokeless tobacco), cessation services (quitline/counseling/doctor), other cessation support (e.g., mobile apps/website/pamphlets, etc.), or no aid.
Among all respondents, at last quit attempt, 28.8% used NRT, 28.0% used an NVP, 12.0% used OPT, 7.8% used a cessation service, 1.7% used a tobacco product, 16.5% other cessation support, and 38.6% used no aid/assistance. Slightly more than half of all smokers and ex-smokers (57.2%) reported using any type of pharmacotherapy (NRT or OPT) and/or an NVP, half-used NRT and/or an NVP (49.9%), and 38.4% used any type of pharmacotherapy (NRT and/or OPT). A quarter of smokers/ex-smokers used a combination of aids. NVPs and NRT were the most prevalent types of cessation aids used in all four countries; however, NRT was more commonly used in Australia relative to NVPs, and in England, NVPs were more commonly used than NRT. The use of NVPs or NRT was more evenly distributed in Canada and the US.
It appears that many smokers are still trying to quit unassisted, rather than utilizing cessation aids or other forms of assistance. Of those who did use assistance, NRT and NVPs were the most common method, which appears to suggest that nicotine substitution is important for smokers when trying to quit smoking.
Clinical practice guidelines in a number of countries state that the most effective smoking cessation method is a combination of pharmacotherapy and face-to-face behavioral support by a health professional. Most quit attempts however are made unassisted, particularly without the use of government-approved cessation medications. This study found that about two in five daily smokers used approved cessation medications (nicotine replacement therapy (NRT) or other approved pharmacotherapies, such as varenicline). Notably, nicotine substitution in the form of either NRT and nicotine vaping products (NVPs) were the most common method of cessation assistance (used by one in two respondents), but the proportion using NRT and/or NVPs varied by country. Few smokers who attempted to quit utilized cessation services such as stop-smoking programs/counseling or quitlines, despite that these types of support are effective in helping smokers manage withdrawals and cravings. Primary healthcare professionals should ask their patients about smoking and offer them evidence-based treatment, as well as be prepared to provide smokers with a referral to trained cessation counselors, particularly when it comes to tailoring intensive treatment programs for regular daily smokers. Additionally, healthcare providers should be prepared to discuss the use of NVPs, particularly if smokers are seeking advice about NVPs, wanting to try/or already using an NVP to quit smoking, have failed repeatedly to quit with other cessation methods, and/or if they do not want to give up tobacco/nicotine use completely.
本研究回顾性描述了在四个高收入国家,当前吸烟者和曾经吸烟者在最近一次戒烟尝试中使用的戒烟辅助工具、戒烟服务和其他类型的帮助。
数据来自澳大利亚、加拿大、英国和美国(美国)的国际烟草控制四国吸烟和蒸气调查的第 3 波(2020 年)。合格的受访者是在过去 24 个月内有过戒烟尝试/戒烟的每日吸烟者或曾经每日吸烟者,共有 3614 名受访者。自我报告的戒烟辅助工具/帮助包括:尼古丁蒸气产品(NVP)、尼古丁替代疗法(NRT)、其他药理学疗法(OPT:伐尼克兰/安非他酮/烟碱)、烟草(非燃烧:加热烟草制品/无烟烟草)、戒烟服务(戒烟热线/咨询/医生)、其他戒烟支持(如移动应用程序/网站/小册子等)或没有辅助。
在所有受访者中,在上一次戒烟尝试中,28.8%使用 NRT,28.0%使用 NVP,12.0%使用 OPT,7.8%使用戒烟服务,1.7%使用烟草产品,16.5%使用其他戒烟支持,38.6%使用没有辅助/帮助。略多于一半的吸烟者和曾经吸烟者(57.2%)报告使用任何类型的药理学疗法(NRT 或 OPT)和/或 NVP,一半使用 NRT 和/或 NVP(49.9%),38.4%使用任何类型的药理学疗法(NRT 和/或 OPT)。四分之一的吸烟者/曾经吸烟者使用了组合辅助工具。NVP 和 NRT 是所有四个国家最常见的戒烟辅助工具类型;然而,在澳大利亚,NRT 比 NVP 更常用,而在英国,NVP 比 NRT 更常用。在加拿大和美国,NVP 或 NRT 的使用分布更为均匀。
似乎许多吸烟者仍在尝试不借助任何帮助而戒烟,而不是使用戒烟辅助工具或其他形式的帮助。那些确实使用过辅助工具的人中,NRT 和 NVP 是最常用的方法,这似乎表明尼古丁替代对试图戒烟的吸烟者很重要。
许多国家的临床实践指南都指出,最有效的戒烟方法是结合药理学疗法和由健康专业人员提供的面对面行为支持。然而,大多数戒烟尝试都是在没有帮助的情况下进行的,特别是没有使用政府批准的戒烟药物。本研究发现,大约五分之二的每日吸烟者使用了批准的戒烟药物(尼古丁替代疗法(NRT)或其他批准的药理学疗法,如伐尼克兰)。值得注意的是,尼古丁替代疗法以 NRT 和尼古丁蒸气产品(NVP)的形式最为常见(有二分之一的受访者使用),但在不同国家使用 NRT 和/或 NVP 的比例有所不同。尽管这些类型的支持有助于吸烟者应对戒断和渴望,但很少有试图戒烟的吸烟者利用戒烟服务,如戒烟计划/咨询或戒烟热线。尽管如此,初级保健专业人员应该询问患者关于吸烟的问题,并为他们提供基于证据的治疗,以及准备为吸烟者提供有针对性的治疗方案,特别是对于经常吸烟的吸烟者,需要制定密集的治疗方案。此外,医疗保健提供者应准备讨论使用 NVP,特别是如果吸烟者正在寻求有关 NVP 的建议,希望尝试/或已经使用 NVP 戒烟,多次使用其他戒烟方法失败,和/或如果他们不想完全放弃烟草/尼古丁的使用。
