数字技术为在人口层面提供戒烟援助创造了机会。然而,发送多个的功效,自动化,量身定制的电子邮件提供动力,退出的支持和信息未知。
计划戒烟的吸烟者(n=1070)被随机分配到(1)27封量身定制的戒烟电子邮件(豪华电子邮件组(DEG)),(2)3至4个定制的电子邮件,带有可下载小册子的链接(基本电子邮件组(BEG))或(3)单个非定制的电子邮件(单个电子邮件组(SEG))。所有电子邮件都包含退出资源的链接。在1个月时评估自我报告的7天点患病率禁欲,注册后3个月和6个月。
跨随访,与SEG(25.8%;OR=1.47,95%CI1.07至2.02,p=0.02)相比,DEG(34%)吸烟者的禁欲显着更高,但BEG(30.8%)和SEG(p=0.13)之间没有差异。结果独立于每天的基线香烟,有兴趣退出,家庭中的吸烟者,使用尼古丁替代疗法(NRT)或伐尼克兰和性别,自身与禁欲有关(ps<0.05)。缺失=吸烟和基于25个数据集的多重归因分析证实了结果。DEG的参与者也更有可能使用非药物辅助(例如,戒烟网站,戒烟类别/诊所)与SEG(OR=1.34,p=0.02,CI1.06至1.71)相比,但是在4周的随访中使用这些或NRT(与不使用)增加了主要在SEG中的随访中的禁欲。
独立定制,多封电子邮件提供支持,戒烟尝试期间的动机和信息很容易部署,为大量计划戒烟的吸烟者提供有效戒烟援助的廉价模式。
Digital technology has created opportunities for delivering smoking cessation assistance at the population level. However, the efficacy of sending multiple, automated, tailored
emails providing motivation, support and information for quitting is unknown.
Smokers planning to quit (n=1070) were randomly assigned to (1) 27 tailored cessation
emails (deluxe email group (DEG)), (2) 3 to 4 tailored
emails with links to downloadable booklets (basic email group (BEG)) or (3) a single non-tailored email (single email group (SEG)). All
emails included links to quitting resources. Self-reported 7-day point-prevalence abstinence was assessed at 1 month, 3 months and 6 months postenrolment.
Across follow-ups, abstinence was significantly greater for smokers in the DEG (34%) compared with the SEG (25.8%; OR=1.47, 95% CI 1.07 to 2.02, p=0.02) but there was no difference between the BEG (30.8%) and the SEG (p=0.13). Results were independent of baseline cigarettes per day, interest in quitting, smoker in household, use of nicotine replacement therapy (NRT) or varenicline and gender, themselves associated with abstinence (ps<0.05). Missing=smoking and multiple imputation analyses based on 25 data sets corroborated results. Participants in the DEG were also more likely to use non-medication aids (eg, quit smoking website, cessation class/clinic) compared with the SEG (OR=1.34, p=0.02, CI 1.06 to 1.71), but use of these or NRT by the 4-week follow-up (vs no use) increased abstinence across follow-ups primarily for those in the SEG.
Stand-alone tailored, multiple
emails providing support, motivation and information during a quit attempt are an easily deployable, inexpensive mode of providing effective cessation assistance to large numbers of smokers planning to quit.
