Effects of Current and Enhanced Tobacco Corrective Messages on Smokers' Intention to Quit Smoking and Intention to Purchase Cigarettes

Charming e-cigarette users with distorted science: a survey examining social media platform use, nicotine-related misinformation and attitudes towards the tobacco industry

OBJECTIVE

To examine the role of social media in promoting recall and belief of distorted science about nicotine and COVID-19 and whether recall and belief predict tobacco industry beliefs.

DESIGN

Young adults aged 18-34 years (N=1225) were surveyed cross-sectionally via online Qualtrics panel. The survey assessed recall and belief in three claims about nicotine and COVID-19 and three about nicotine in general followed by assessments of industry beliefs and use of social media. Ordinal logistic regression with robust standard errors controlling for gender, race/ethnicity, education, current e-cigarette use and age was used to examine relationships between variables.

RESULTS

Twitter use was associated with higher odds of recall (OR=1.21, 95% CI=1.01 to 1.44) and belief (OR=1.26, 95% CI=1.04 to 1.52) in COVID-19-specific distorted science. YouTube use was associated with higher odds of believing COVID-19-specific distorted science (OR=1.32, 95% CI=1.09 to 1.60). Reddit use was associated with lower odds of believing COVID-19-specific distorted science (OR=0.72, 95% CI=0.59 to 0.88). Recall (OR=1.26, 95% CI=1.07 to 1.47) and belief (OR=1.28, 95% CI=1.09 to 1.50) in distorted science about nicotine in general as well as belief in distorted science specific to COVID-19 (OR=1.61, 95% CI=1.34 to 1.95) were associated with more positive beliefs about the tobacco industry. Belief in distorted science about nicotine in general was also associated with more negative beliefs about the tobacco industry (OR=1.18, 95% CI=1.02 to 1.35).

CONCLUSIONS

Use of social media platforms may help to both spread and dispel distorted science about nicotine. Addressing distorted science about nicotine is important, as it appears to be associated with more favourable views of the tobacco industry which may erode public support for effective regulation.

Association of Exposure to Court-Ordered Tobacco Industry Antismoking Advertisements With Intentions and Attempts to Quit Smoking Among US Adults

IMPORTANCE

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.

OBJECTIVES

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.

EXPOSURE

Reported exposure to antismoking messages.

MAIN OUTCOMES AND MEASURES

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.

RESULTS

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.

CONCLUSIONS AND RELEVANCE

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.

Broadcast reach and self-reported exposure to court-ordered corrective statements on cigarette harms

In August 2006, U.S. District Court Judge Gladys Kessler ordered four tobacco companies to disseminate court-approved corrective statements on five topics pertaining to health hazards of cigarette smoking. Based on the 2018 Health Information National Trends Survey (HINTS), approximately 50% of U.S. smokers viewed at least one corrective statement via television or newspaper during the first six months of the airings/publications (November 2017-April 2018). Using televised gross rating points (GRPs) and cross-sectional data from the 2018 HINTS (n = 3484) and 2019 HINTS (n = 3331), the current study extends previous ones by estimating broadcast reach/frequency and the moderating effect of survey year on smokers' exposure to a corrective statement. The weighted percentage of participants who viewed a corrective statement was significantly greater in the 2019 versus 2018 HINTS for smokers (64.3% vs. 50.5%, χ² _1df = 5.85, p = .01), but not for non-smokers (39% in 2018/2019, χ² _1df = 0.02; p = .88); this differential effect was evidenced by a significant interaction term (OR = 2.0(1.2, 3.2), p < .001). This study also revealed that the televised reach of the corrective statements to the U.S. population (43.5 GRPs/43.5%) was comparable to the published estimate from the 2018 HINTS (40.6%). The frequency of exposure to any corrective statement in the first six months of televised airings was only 0.68 exposures/month, an estimate that does not meet CDC Best Practices. Yet, as evidenced by the significant interaction with survey year, it is likely that the addition of messages to tobacco company websites and cigarette package onserts may have contributed to smokers' greater exposure to a corrective statement.
