In 2006, a US district court judge ordered tobacco companies to sponsor nationwide antismoking advertising campaigns. This landmark ruling and its subsequent execution represent an unprecedented tobacco control event; however, the association of this campaign with intentions and/or attempts to quit smoking is unknown.
To assess the reach of the expanded court-ordered tobacco industry antismoking advertisements (via television, newspapers, tobacco company websites, and/or cigarette packages), to examine associations between exposure to industry antismoking advertisements and intentions and/or attempts to quit smoking among cigarette smokers, and to calculate the numbers of US smokers who would have quit intentions associated with exposure to multiple advertisements.
DESIGN, SETTING, AND PARTICIPANTS: Data for this study were obtained from 5309 US adults, including 610 smokers, who responded to the Health Information National Trends Survey, a nationally representative cross-sectional survey conducted from January 22 to April 30, 2019. Respondents were representatives of households selected by equal-probability sampling of a database of US residential addresses.
Reported exposure to antismoking messages.
Cigarette smoking cessation attempt in the past 12 months and intentions to quit cigarette smoking in the next 6 months. Covariates were age, sex, household annual income, race/ethnicity, educational level, and geographical residence. Data were weighted to be nationally representative after applying survey weights specified for the survey cycle.
The overall sample of 5309 respondents were a mean (SD) age of 55.6 (19.1) years and included 3073 women (51.2%), 3037 non-Hispanic white respondents (59.1%), 4645 respondents who lived in urban US areas (84.7%), and 610 current smokers (12.5%). Findings indicate that 2464 US adults (45.8%; 95% CI, 43.2%-48.5%) and 410 current smokers (66.8%; 95% CI, 61.1%-72.4%) were exposed to antismoking advertisements. Exposure to multiple antismoking messages was associated with 2.19 (95% CI, 1.10-4.34) greater odds of having intentions to quit cigarette smoking but was not associated with attempts to quit (adjusted odds ratio, 1.31; 95% CI, 0.69-2.52). Furthermore, an examination of the association of cumulative exposure to antismoking messages with cessation intentions revealed that, with each additional exposure to an antismoking message, the odds of smoking cessation intentions increased by 1.21 (95% CI, 1.02-1.44). If all smokers were to be exposed to multiple antitobacco messages, there could be an estimated 3.98 million (95% CI, 492 480-7 223 040) current smokers in the United States with intentions to quit.
Although the reach of court-ordered industry advertisements increased among smokers, the reach of these advertisements within the general population remains suboptimal. The finding that industry advertisements helped smokers consider quitting highlights their potential to aid smoking cessation. However, the lack of association with actual attempts to quit suggests that the industry antismoking advertisement campaigns were inadequate. The design and content of industry antismoking advertisement campaigns should be enhanced to help smokers quit.
2006 年,美国地区法院法官命令烟草公司赞助全国范围的反吸烟广告活动。这一具有里程碑意义的裁决及其后续执行代表了一场前所未有的烟草控制事件;然而,目前尚不清楚该活动与意图和/或尝试戒烟之间的关联。
评估扩大的法院命令烟草业反吸烟广告(通过电视、报纸、烟草公司网站和/或香烟包装)的覆盖范围,研究接触行业反吸烟广告与吸烟人群意图和/或尝试戒烟之间的关系,并计算与接触多则广告相关的美国吸烟者的戒烟意愿人数。
设计、地点和参与者:本研究的数据来自 5309 名美国成年人,其中包括 610 名吸烟者,他们对健康信息国家趋势调查做出了回应,这是一项具有全国代表性的横断面调查,于 2019 年 1 月 22 日至 4 月 30 日进行。受访者是从美国住宅地址数据库中通过等概率抽样选择的家庭代表。
报告接触反吸烟信息。
过去 12 个月内的吸烟尝试和未来 6 个月内的戒烟意愿。协变量为年龄、性别、家庭年收入、种族/族裔、教育水平和地理位置。数据经过加权处理,以在应用特定于调查周期的调查权重后具有全国代表性。
在 5309 名总体样本中,受访者的平均(标准差)年龄为 55.6(19.1)岁,包括 3073 名女性(51.2%)、3037 名非西班牙裔白人受访者(59.1%)、4645 名居住在美国城市地区的受访者(84.7%)和 610 名当前吸烟者(12.5%)。研究结果表明,2464 名美国成年人(45.8%;95%CI,43.2%-48.5%)和 410 名当前吸烟者(66.8%;95%CI,61.1%-72.4%)接触了反吸烟广告。接触多种反吸烟信息与戒烟意愿增加 2.19 倍(95%CI,1.10-4.34)相关,但与戒烟尝试无关(调整后的比值比,1.31;95%CI,0.69-2.52)。此外,对累积接触反吸烟信息与戒烟意愿的关系进行检查后发现,每额外接触一则反吸烟信息,戒烟意愿增加 1.21 倍(95%CI,1.02-1.44)。如果所有吸烟者都接触到多种反烟草信息,美国可能会有 398 万(95%CI,492480-7223040)名当前吸烟者有意戒烟。
尽管法院命令的行业广告在吸烟者中的传播范围有所扩大,但在普通人群中的传播范围仍然不理想。广告帮助吸烟者考虑戒烟的发现突出了它们在帮助戒烟方面的潜力。然而,与实际戒烟尝试缺乏关联表明,行业反吸烟广告活动是不够的。应加强行业反吸烟广告活动的设计和内容,以帮助吸烟者戒烟。
