Relative efficacy of cigarillo warning statements in text and pictorial formats: An experimental study among a sample of US young adults.

INTRODUCTION: Health warning labels (HWLs) communicate the health risks of cigar use and can decrease use when on cigar packages. This study assessed the relative efficacy of six FDA-proposed individual warning statements in text and pictorial format. METHODS: A sample of young adults (ages 18-29) were randomized to a text or pictorial warning condition on generic cigarillo packages. The warning statements were about lung cancer and heart disease; cancers of the mouth and throat; secondhand smoke; not a safe alternative; nicotine/addiction; and harm to baby. Negative emotional reactions, cognitive elaboration, and perceived message effectiveness (PME) were assessed for each warning using linear mixed models. RESULTS: Of the 661 participants, 47.3% reported ever cigarillo smoking, 32.7% current smoking, and 20% were susceptible. In the pictorial format, cancers of the mouth and throat elicited lower levels of anxiety compared to secondhand smoke, not a safe alternative, nicotine/addiction, and harm to baby (ps<0.001). Pictorial HWLs with human imagery induced high anxiety, sadness, fear, and guilt reactions (p<0.001) and higher PME (p=0.011) compared to pictorial HWLs with diseased body parts. Compared to the text HWL cancers of the mouth and throat, the text HWL harm to baby elicited higher anxiety (p=0.003), sadness (p=0.002) and PME (p<0.001). CONCLUSIONS: Pictorial HWLs depicting people or human imagery, rather than images of diseased organs or body parts, to represent health effects elicited the most negative emotional reactions, such as anxiety and guilt, and higher PME. Including such images and texts highlighting effects on vulnerable populations like babies can better communicate cigarillo health risks, aiming to curb cigarillo use among young people. IMPLICATIONS: The study suggests that pictorial health warning labels (HWLs) with human imagery significantly enhance the communication of cigarillo smoking risks compared to images of diseased organs. These HWLs evoke stronger emotional responses, particularly anxiety and guilt, and higher perceived message effectiveness by depicting a recognizable person. Furthermore, text-only warnings describing the smoking effect on vulnerable populations such as babies might have a higher impact on young adults. This evidence supports a strategic shift in FDA policies to include such impactful images and texts, which could potentially lead to a significant reduction in cigarillo use among young people. Our findings underscore the urgent need for continued research and implementation of these enhanced warning labels to improve public health outcomes.

Differences in Presenting Health Warning Labels on Hookah Venue Menus Between Immersive Virtual Reality and Online Surveys.

BACKGROUND: Virtual reality (VR) platforms can simulate the real world, whereas online surveys are efficient settings for assessing and testing information. In this study, the effects of presenting health warning labels (HWLs) on hookah venue menus were compared between these two message-testing settings. METHODS: Separate studies were conducted in VR (n = 96) and online survey (n = 213) settings. Participants in both studies were randomly assigned to view menus with or without HWLs. This secondary data analysis compared outcomes between settings after propensity score weighting to account for differences in age, race, marital status, and education between studies. RESULTS: Significant between-study differences were noted for the effects of HWLs on people's perceptions of the absolute harm of hookah smoking (p = 0.0363), the relative harm of hookah compared to cigarettes (p < 0.001), the absolute addictiveness of hookah (p < 0.001), and the relative addictiveness of hookah compared to cigarettes (p = 0.0352). When outcome variables differed significantly between the HWL and control conditions in only one of the two studies, smaller p-values were identified for the online survey setting than for the VR setting. CONCLUSIONS: This study represents the first direct comparison of the effects of hookah HWLs between two message-testing settings. HWLs tested in the online survey setting were associated with larger shifts in attitudes and beliefs than those tested in the VR setting, suggesting that the effectiveness of hookah HWLs on attitudes and beliefs may be moderated by the message-testing platform. Additional real-world experiments remain necessary to determine whether either setting can accurately assess the effectiveness of HWLs.

Is evoking fear effective? Exploratory findings from a randomised experiment on the impacts of health warning labels on sugar-sweetened beverages.

OBJECTIVE: Health warning labels (HWL) have been suggested to be effective in reducing consumption of sugar-sweetened beverages (SSB). Yet, the efficacy and acceptability of SSB HWL of different formats (textual/pictorial) and severity remain unclear. This exploratory study aims to examine the extent and mechanism through which HWL of different formats and severity may affect responses towards the HWL and SSB consumption. DESIGN: Randomised online experiment. Participants were exposed to images of a hypothetical SSB bearing a HWL of one of three conditions: text-only HWL, moderately severe pictorial HWL and highly severe pictorial HWL. They then responded to theory-based affective, cognitive and behavioural measures. SETTING: Singapore. PARTICIPANTS: One hundred and twenty-seven young adult consumers from a public university. RESULTS: Direct effects were found for fear, avoidance, reactance and acceptability of the HWL, but not attitude, intention or motivation to consume less SSB. Pictorial (moderately severe and highly severe) HWL were associated with greater fear, avoidance, and reactance, and lower acceptability than text-only HWL. There was weak evidence that highly severe pictorial HWL resulted in greater reactance than moderately severe pictorial HWL. Fear mediated the effect of HWL of different severity levels on avoidance, reactance, intention and motivation, but not for attitude or acceptability. CONCLUSIONS: Exploratory findings indicate that although pictorial HWL were less acceptable, they may still be effective in influencing intention and motivation to reduce SSB consumption through the psychological mechanism of fear. Hence, graphic HWL should not be dismissed too quickly when considering strategies for reducing SSB consumption.

Effects of immediate and distant health consequences: different types of health warning messages on sweets affect the purchase probability.

BACKGROUND: Several health control policies have been discussed as a regulatory approach to tackle the increasing prevalence of obesity and other health risks related to sugar consumption. Health warnings, like the ones used in tobacco control worldwide, are one of the most promising approaches. However, in the case of health warning messages for food products, it is much more complicated and involves much more consumer involvement than tobacco guidance. Therefore, it is important to better understand the efficacy, evaluation, and reactance of health warning labels in the food sector regarding consumers' behavior, persuasion, and perceptions. The aim of this study was to examine how different types (design and message) of health warning messages in combination with graphical applications affect consumer behavior. METHODS: In a 3 × 3 × 3 symmetrical design, 1,040 German participants completed an online discrete choice experiment including various text-only and image-and-text health warning labels on sweets. An accompanying questionnaire assessed socio-demographic variables as well as psychometric scales to understand the relationship between fear, control, reactance, and shocking/inhibiting/mediating health-related warnings. RESULTS: Our results suggest that especially emotional graphical images combined with text health warning labels might be more influential. The health effects of immediate (caries) and more distant health consequences (diabetes/obesity) differ in their impact. Further, results show that especially when consumers engage in a danger control process for overweight, warning messages have a negative impact on their choices. CONCLUSION: Hence, warning labels on sweets can potentially be a decisive factor when communicating health threats related to excessive sugar consumption. In the context of a targeted health policy, we see the need for further research, especially concerning the perception and understanding of noncommunicable diseases (NCDs) in the population.

The association between viewing cigarette health warning labels and intention to quit smoking among Chinese adult smokers: support for including health outcome content and culturally specific messages.

BACKGROUND: Tailored themes of pictorial health warning labels (HWLs) that considers specific cultural dimensions and within a specific policy/historical context can motivate behavior change, such as provoking smokers to think about quitting. Currently in China, the HWLs on cigarettes are text-only. This study designed pictorial HWLs using different themes to explore and examine the association between viewing pictorial HWLs and participants' intention to quit smoking. The themes included: (1) Self-harm from using cigarettes, (2) Harming family or children with secondhand smoke, (3) Complying with existing smoke-free policies, and (4) Cigarette gift giving practices. METHODS: A cross-sectional randomized experimental survey was conducted among 1,625 smokers in Beijing (n = 545), Shanghai (n = 541), and Shenzhen (n = 539) during 2017. Before and after viewing eight pictorial HWLs of one theme, participants were asked if they had plans to quit smoking within the next month, within the next 6 months, beyond the next 6 months, or not at all. Ordinal logistic regression, Wilcoxon and Chi-square tests were used to analyze the data. RESULTS: After viewing the HWLs, 434 participants (26.9%) reported an intention to quit smoking sooner, 987 (61.2%) reported the same intention to quit, and 191 (11.8%) reported an intention to quit later. The pre-post change in intention to quit was statistically significant among all participants and participants under each theme (p > 0.05). Participants who rated the effectiveness of the HWL communicating how secondhand smoke harms children had 1.13 (95% CI 1.01-1.27) greater odds of reporting an intention to quit sooner compared to those viewing labels from the other themes, adjusting for covariates. Female participants and participants with annual household income more than 100,000RMB had 1.39 (95% CI 1.14-1.69) and 1.29 (95% CI 1.04-1.60) greater odds of reporting an intention to quit sooner compared to their counterparts across the entire sample. CONCLUSIONS: Findings of this study provide evidence of an association between all four pictorial HWL themes and smokers' intention to quit smoking. These findings can help inform what HWL themes might be appropriate when China implements pictorial health warning labels.

Exploring context specific anti-smoking warning labels on cigarette packs: A quasi-experiment.

OBJECTIVE: To evaluate the impact of introducing newly-designed warning labels in relation to the available conventional cigarette packs. METHODS: The quasi-experimental study was conducted at four co-educational academic institutions selected using cluster random sampling technique in Gulshan-e-Iqbal town of Karachi from September 2016 to October 2017. The respondents, aged 16-24 years, were exposed with an experimental condition using five graphic cards; each comprising of two separate labels; label 1 being a cigarette pack currently rotated, and label 2 being the newly designed graphic and text warning label. Each participant responded over efficacy measures for each label separately. The difference in the efficacy scores between the two labels was assessed using repeated measure ANOVA with Bonferroni correction in analysis. RESULTS: Of the 388 students, 256(66%) were males and 132(34%) were females. The overall mean age was 18±2.76 years. Also, 188(48.5%) subjects were studying in higher secondary, 179(46.1%) undergraduate and 21(5.4%) postgraduate level. Of them, 104(26.8%) were ever-smokers and 284(73.2%) reported to be never-smokers. A difference was observed in the efficacy of the newly designed label "poverty" compared with current cigarette pack on the measure of not to start smoking(p=0.006). Never-smoking males perceived newly-designed label element 'dead person' as fear-arousing (p=0.045), while never-smoking females considered 'look after family' as efficacious (p=0.024). CONCLUSIONS: There was some evidence of variation in efficacy scores after stratifying on gender and smoking status. A more holistic approach is needed in this regard.

General and specific graphic health warning labels reduce willingness to consume sugar-sweetened beverages.

Sugar-sweetened beverage (SSB) consumption is associated with obesity and other severe negative health consequences. The present study examined the effectiveness of two types of health warning labels (HWLs) in modulating dietary choices for SSBs: specific HWLs, presenting health consequences associated with consuming SSBs, and general HWLs, presenting health consequences of an unhealthy diet and obesity. While electroencephalography (EEG) was recorded, 63 participants completed a computer-based task in which they were first randomly allocated to view either SBB-specific, general, or non-warning control HWLs. They then viewed images of a range of SSB products, varying on perceived healthiness and tastiness, and rated their willingness to consume (WTC) each one. Linear mixed-effect model analyses revealed that general and specific HWLs both decreased WTC SSBs perceived as tasty, compared to the control condition. For general HWLs, this effect was reduced for SSBs perceived to be healthy, suggesting that specific HWLs may be more effective at reducing SSB consumption. The EEG data showed that SSBs considered unhealthy elicited greater N1 amplitudes, and tasty SSBs elicited greater late positive potential (LPP) amplitudes, possibly reflecting attentional allocation and craving responses, respectively. However, no strong differences between HWL types were found. Taken together, the results suggest that graphic HWLs, both general and specific, have the potential to reduce SSB consumption, but they do not strongly modulate craving-related neural responses to SSBs.

Effects of pairing health warning labels with energy-dense snack foods on food choice and attitudes: Online experimental study.

BACKGROUND: There is limited evidence concerning the potential effectiveness of health warning labels (HWLs) using images and text to depict possible negative health consequences of consumption, for reducing selection of energy-dense snack foods. Furthermore, the underlying mechanisms have received little attention; particularly effects on implicit attitudes, which previous work has shown may mediate the effect of aversive images on food choice. AIM: To assess the impact of pairing image- and text-based HWLs with energy-dense snack foods on a) the selection of, and b) implicit and explicit attitudes towards, those foods. METHODS: Online experimental study with a representative UK sample (n = 1185), using a 2(Image/No Image) x 2(Text/No Text) factorial between-subjects design. Participants were randomised to one of four study arms, viewing snack food images paired with either: image-only HWLs, text-only HWLs, image-and-text HWLs, or no HWLs (control). HWLs concerned various negative health consequences of excess energy intake, such as heart disease and type 2 diabetes. The primary outcome was hypothetical food choice (energy-dense snack foods versus fruit), assessed post-intervention. Secondary outcomes were implicit and explicit attitudes. RESULTS: Neither food choice nor explicit attitudes were changed significantly by any type of HWL. Implicit attitudes towards energy-dense snack foods were more negative after exposure to text-only or image-and-text HWLs. Both implicit and explicit attitudes predicted unique variance in food choice. CONCLUSIONS: This study suggests that short-term repeated exposure to HWLs paired with energy-dense snack foods may not consistently alter food choices, but can change implicit attitudes associated with food choices. Further laboratory and field studies are needed to more definitively assess the impact of HWLs on food selection and consumption in applied contexts and over time, as well as delineate underlying mechanisms.

Image-and-text health warning labels on alcohol and food: potential effectiveness and acceptability.

BACKGROUND: Health warning labels (HWLs) using images and text to depict the negative health consequences of tobacco consumption are effective and acceptable for changing smoking-related outcomes. There is currently limited evidence concerning their potential use for reducing consumption of alcoholic drinks and energy-dense foods. The aim of this research was to describe the potential effectiveness and acceptability of image-and-text (also known as pictorial or graphic) HWLs applied to: i. alcoholic drinks and ii. energy-dense snack foods. METHODS: Two online studies were conducted using between-subjects designs with general population samples. Participants rated one of 21 image-and-text HWLs on alcoholic drinks (n = 5528), or one of 18 image-and-text HWLs on energy-dense snacks (n = 4618). HWLs comprised a graphic image with explanatory text, depicting, respectively, seven diseases linked to excess alcohol consumption, and six diseases linked to excess energy intake. Diseases included heart disease and various cancers. Outcomes were negative emotional arousal, desire to consume the labelled product, and acceptability of the label. Free-text comments relating to HWLs were content analysed. RESULTS: For both alcoholic drinks and energy-dense snacks, HWLs depicting bowel cancer generated the highest levels of negative emotional arousal and lowest desire to consume the product, but were the least acceptable. Acceptability was generally low for HWLs applied to alcohol, with 3 of 21 rated as acceptable, and was generally high for snacks, with 13 of 18 rated as acceptable. The majority of free-text comments expressed negative reactions to HWLs on alcohol or energy-dense snacks. CONCLUSIONS: Image-and-text health warning labels depicting bowel cancer showed greatest potential for reducing selection and consumption of alcoholic drinks and energy-dense snacks, although they were the least acceptable. Laboratory and field studies are needed to assess their impact on selection and consumption.

The association between new graphic health warning labels on tobacco products and attitudes toward smoking among south Korean adolescents: a national cross-sectional study.

BACKGROUND: Graphic health warning labels (GHWLs) on tobacco products are more effective than text warnings for communicating the risk of smoking. The implementation of GHWLs can prevent adolescents from initiating smoking. Therefore, this study examined the association between GHWLs newly implemented on December 23, 2016, in South Korea and attitudes toward smoking among adolescents. METHODS: This post-implementation cross-sectional analysis examined the responses of 62,276 students (31,624 boys and 30,652 girls) who participated in the 2017 Web-based Korean Youth Risk Behavior Survey, which was completed anonymously as a self-administered questionnaire by middle and high school students. Multinomial logistic regression was applied to explore the attitudes toward smoking among the youth (13-18 years old) who have been exposed to GHWLs in order to identify relationship of exposure to the GHWLs with smoking initiation and awareness of the danger of smoking. RESULTS: Six months after implementation, 69.4% of adolescents reported having been exposed to GHWLs in the previous 30 days. Among those exposed to GHWLs both boys and girls in grade 7 were significantly more likely than grade 12 high school students to decide not to start smoking (boys: AOR = 3.96, 95% CI 3.31-4.75, p < 0.001; girls: AOR = 2.76, 95% CI 2.32-3.30, p < 0.001) and to think that smoking was dangerous to their health (boys: AOR = 3.01, 95% CI 2.52-3.58, p < 0.001; girls: AOR = 2.42, 95% CI 2.03-3.88, p < 0.001) after seeing GHWLs. These associations were greater for adolescents who had experienced smoking-prevention education or had been exposed to anti-tobacco advertisements. However, those who smoked, used e-cigarettes, or experienced secondhand smoking were significantly less likely to decide not to smoke and to view smoking as dangerous. CONCLUSIONS: To maintain the perception of the harm of tobacco from childhood through adolescence, the government should implement both comprehensive tobacco controls, including smoking-prevention education in schools, and measures to encourage a smoke-free environment in homes.

Impact of health warning labels on snack selection: An online experimental study.

Excessive consumption of energy-dense food increases the risk of obesity, which in turn increases the risk of non-communicable diseases, including heart disease, type 2 diabetes and most non-smoking-related cancers. Health warning labels (HWLs) that communicate the adverse health consequences of excess energy consumption could reduce intake of energy-dense foods. The aim of the current study was to estimate the impact on selection of energy-dense snacks of (a) image-and-text HWLs (b) text-only HWLs and (c) calorie information. In a between-subjects, 3 (HWL: image-and-text, text-only, no label) x 2 (calorie information: present, absent), factorial experimental design, participants (N = 4134) were randomised to view a selection of energy-dense and non-energy-dense snacks with one of five label types or no label. The primary outcome was the proportion of participants selecting an energy-dense snack in a hypothetical vending machine task. The proportion of participants selecting an energy-dense snack was reduced in all label groups, relative to the no label group (no label: 59%; calories only: 54%; text-only HWL: 48%; text-only HWL with calories: 44%; image-and-text HWL: 37%; image-and-text HWL with calories: 38%). Compared to the no label group, participants were least likely to select an energy-dense snack in the image-and-text HWL group (OR = 0.46, 95%CI = 0.40, 0.54, p < 0.001). Health warning labels - particularly those including an image and text - have the potential to reduce selection of energy-dense snacks in an online setting. Their impact on selection and consumption in real-world settings awaits testing.

The impact of 'on-pack' pictorial health warning labels and calorie information labels on drink choice: A laboratory experiment.

Sugar-sweetened beverages (SSBs) are one of the largest added sugar sources to diets in the UK and USA. Health warning labels reduce hypothetical selection of SSBs in online studies but uncertainty surrounds their impact on selection of drinks for consumption. Calorie information labels are also promising but their impact on SSB selection is unclear. This laboratory study assessed the impact on SSB selection of 'on-pack' labels placed directly on physical products: i.a pictorial health warning label depicting an adverse health consequence of excess sugar consumption; and ii.calorie information labels. Potential moderation of any effects by socio-economic position (SEP) was also examined. Participants - 401 adults, resident in England, approximately half of whom were of lower SEP and half of higher SEP, were asked to select a drink from a range of two non-SSBs and four SSBs (subsequent to completing a separate study assessing the effects of food availability on snack selection). The drinks included 'on-pack' labels according to randomisation: Group 1: pictorial health warning label on SSBs; Group 2: calorie information label on all drinks; Group 3: no additional label. The primary outcome was the proportion of participants selecting an SSB. Compared to not having additional labels (39%), neither the pictorial health warning label (40%) nor calorie information labels (43%) affected the proportion of participants selecting an SSB. Lower SEP participants (45%) were more likely to select an SSB compared to those of higher SEP (35%), but SEP did not moderate the impact of labels on drink selection. In conclusion, pictorial health warning labels may be less effective in reducing SSB selection in lab-based compared with online settings, or depending on label design and placement. Findings suggest that effects might be absent when choosing from real products with actual 'on-pack' labels, positioned in a 'realistic' manner. Field studies are needed to further assess the impact of 'on-pack' SSB warning labels in real-world settings to rule out the possible contribution of study design factors.

Health warning labels describing snus as less harmful than smoking: effects on perceptions of risk.

BACKGROUND: Using snus (Swedish moist snuff) is less harmful than smoking, but health warning labels (HWLs) on snus products do not reflect this relation. There are few studies on the effects of comparative risk information in snus warning labels. The purpose of this experiment is to examine whether risk perceptions differ after exposure to non-comparative vs. comparative risk information in snus warning labels. METHODS: A total of 254 Norwegians aged 19-69 were exposed to pictures of snus packages in one of four HWL conditions: non-comparative EU-based ("Snus is damaging to your health"), control (the text "Snus" only), general comparative risk ("Snus is less damaging to your health than smoking"), or percentage comparative risk ("Snus is 90% less damaging to your health than smoking"). Perceptions of risk from snus use and smoking were measured before (pre) and during (post) exposure to the HWL. Changes from pre to post in (1) perceptions of risk from snus use and (2) perceptions of risk differences from snus use versus smoking were tested in repeated measures ANOVAs with current snus and cigarette use as covariates. RESULTS: Both the perceived risks from snus use and its perceived risk difference to smoking decreased more in the control and the percentage HWL conditions than in the EU-based HWL condition. When comparing the general comparative risk and the EU-based HWL, a similar difference was found for the perceived risk difference, but not for the separate measure of snus risk. Both the snus risk and risk difference perception decreased more for the percentage than for the general relative risk HWL. CONCLUSIONS: The non-comparative EU-based HWL claiming that "Snus is health damaging" maintains a high level of perceived risk from snus use, while no HWL and the suggested comparative HWLs adjust perceptions of risk in the direction of lower harm from snus use. An HWL describing snus as 90% less harmful than smoking was more effective than a general claim.

Effect of message congruency on attention and recall in pictorial health warning labels.

OBJECTIVE: The nine pictorial health warning labels (PWLs) proposed by the US Food and Drug Administration vary in format and feature of visual and textual information. Congruency is the degree to which visual and textual features reflect a common theme. This characteristic can affect attention and recall of label content. This study investigates the effect of congruency in PWLs on smoker's attention and recall of label content. METHODS: 120 daily smokers were randomly assigned to view either congruent or incongruent PWLs, while having their eye movements recorded. Participants were asked to recall label content immediately after exposure and 5 days later. RESULTS: Overall, the image was viewed more and recalled better than the text. Smokers in the incongruent condition spent more time focusing on the text than smokers in the congruent condition (p=0.03), but dwell time of the image did not differ. Despite lower dwell time on the text, smokers in the congruent condition were more likely to correctly recall it on day 1 (p=0.02) and the risk message of the PWLs on both day 1 (p=0.01) and day 5 (p=0.006) than smokers in the incongruent condition. CONCLUSIONS: This study identifies an important design feature of PWLs and demonstrates objective differences in how smokers process PWLs. Our results suggest that message congruency between visual and textual information is beneficial to recall of label content. Moreover, images captured and held smokers' attention better than the text.

Noticing cigarette health warnings and support for new health warnings among non-smokers in China: findings from the International Tobacco Control project (ITC) China survey.

BACKGROUND: Health warnings labels (HWLs) have the potential to effectively communicate the health risks of smoking to smokers and non-smokers, and encourage smokers to quit. This study sought to examine whether non-smokers in China notice the current text-only HWLs and whether they support adding more health information and including pictures on HWLs. METHODS: Adult non-smokers (n = 1324) were drawn from Wave 4 (September 2011-November 2012) of the International Tobacco Control (ITC) China Survey. The proportion of non-smokers who noticed the HWLs, and supported adding more health information and pictures to the HWLs was examined. Additionally, the relation between non-smokers' demographic characteristics, including whether they had a smoking partner, their number of smoking friends, and noticing the HWLs and support for adding health information and pictures was examined. Because the HWLs changed during the survey period (April 2012), differences between non-smokers who completed the survey before and after the change were examined. RESULTS: 12.2% reported they noticed the HWLs often in the last month. The multivariate model, adjusting for demographics showed that respondents with a smoking partner (OR = 2.41, 95% CI 1.42-4.13, p = 0.001) noticed the HWLs more often. 64.8% of respondents agreed that the HWLs should have more information, and 80.2% supported including pictures. The multivariate model showed that non-smokers who completed the survey after the HWLs were implemented (OR = 0.63, 95% CI 0.40-0.99, p = 0.04) were less likely to support adding more health information. The multivariate model showed a significant relation between having a smoking partner and supporting pictorial HWLs (OR = 2.03, 95% CI 1.24-3.33, p = 0.005). CONCLUSIONS: The findings indicate that the Chinese HWLs are noticed by a minority of non-smokers and that non-smokers strongly support strengthening the Chinese warning labels with more health information and pictures. Additionally, because the HWLs are noticed more often by non-smokers with a smoking spouse/partner, HWLs could be used to communicate the dangers of smoking and secondhand smoke exposure to non-smokers.

An examination of the effectiveness of health warning labels on smokeless tobacco products in four states in India: findings from the TCP India cohort survey.

BACKGROUND: In 2009, after many delays and changes, India introduced a single pictorial health warning label (HWL) on smokeless tobacco (SLT) packing-a symbolic image of a scorpion covering 40% of the front surface. In 2011, the scorpion was replaced with 4 graphic images. This paper tested the effectiveness of SLT HWLs in India and whether the 2011 change from symbolic to graphic images increased their effectiveness. METHODS: Data were from a cohort of 4733 adult SLT users (age15+) of the Tobacco Control Project (TCP) India Survey from 4 states. The surveys included key indicators of health warning effectiveness, including warning salience, and cognitive, emotional, and behavioral responses to the warnings. RESULTS: The HWL change from symbolic to graphic did not result in significant increases on any of the HWL outcome indicators. A substantial minority of SLT users were unaware that SLT packages contained HWLs (27% at both waves). Noticing the warnings was also remarkably low at both waves (W1 = 34.3%, W2 = 28.1%). These effects carried over to the cognitive and behavioural measures, where among those who noticed HWLs, about one-third reported forgoing SLT at least once because of the HWLs, and fewer than 20% reported that HWLs made them think about SLT risks or about quitting SLT. Even fewer reported avoiding HWLs (8.1 to 11.6%). Among those who quit using SLT by post-policy, awareness that SLT packaging contained HWLs was significantly greater at post-policy (86.8%) compared to pre-policy (77.8%, p = 0.02). Quitters were also significantly more aware of the post-policy HWLs compared to those who continued to use SLT (p < 0.001). CONCLUSIONS: Health warnings on SLT packages in India are low in effectiveness, and the change from the symbolic warning (pre-policy) to graphic HWLs (post-policy) did not lead to significant increases of effectiveness on any of the HWL indicators among those who continued to use SLT products, thus suggesting that changing an image alone is not enough to have an impact. There is a critical need to implement SLT HWLs in India that are more salient (large in size and on the front and back of the package) and impactful, which following from studies of HWLs on cigarette packaging, would have strong potential to increase awareness of the harms of SLT and to motivate quitting.

Self-reported attention and responses to cigarette package labels at the end of a two-week randomized trial of cigarette package labeling configurations.

INTRODUCTION: Cigarette package inserts that describe quitting benefits and tips may promote cessation; however, research is needed to understand better their effects, including potentially enhancing the effects of pictorial health warning labels (PHWLs). METHODS: A randomized trial with a 2×2 factorial design was conducted with adult smokers (n=356) assigned to either small text-only health warning labels (HWLs; control); inserts with cessation messages, and the small text-only HWLs (inserts-only); large PHWLs (PHWLs-only); both inserts and PHWLs (inserts + PHWLs). Participants received a 14-day supply of their preferred cigarettes with packs labeled to reflect their group. Upon finishing the trial, participants reported their past 14-day frequency of noticing, reading, thinking about smoking harms and cessation benefits, talking about labels, and forgoing cigarettes because of the labels. Ordered logistic models regressed these outcomes on labeling groups, and mediation analyses assessed whether attention (i.e. noticing, reading) to labels mediated effects of labeling exposure on other outcomes (i.e. thinking about harms/benefits, talking, forgoing). RESULTS: The inserts + PHWLs group reported higher frequencies than the control group for all outcomes. Compared to the control group, both the inserts-only and PHWLs-only groups reported higher frequency of noticing (AOR=3.53 and 2.46, respectively) and reading labels (AOR=2.89 and 1.71), thinking about smoking risks because of the labels (AOR=1.93 and 1.82), and talking about labels (AOR=2.30 and 2.70). Participants in the inserts-only group also reported more frequent thinking about quitting benefits (AOR=1.98). Attention mediated all labeling effects except for the contrast between PHWLs only and control. CONCLUSIONS: Compared to text-only HWLS, cigarette labeling that involves inserts, PHWLs, or both appears more effective at drawing attention to warnings, which mediated the effects on cessation-related psychosocial and behavioral outcomes.

Exploring the effects of cannabis health warnings on protective health intentions among US adults in legal recreational states.

BACKGROUND: As cannabis policy trends toward liberalization, assessing cannabis health warning effects becomes increasingly important. This study investigated underlying mechanisms accounting for the effectiveness of cannabis health warnings on protective health intentions. METHOD: A sample of 1,095 adults (21+) living in legal recreational US states who reported using cannabis in the past 12 months participated in an online experiment. Participants were randomly assigned to view cannabis health warnings that described risks of impaired driving, mental health, and smoke exposure and varied pictures and text (vs. text-only) attributes in warnings. Outcomes were message reactions (cognitive elaboration, fear, and hope), attitudes and beliefs (perceived severity of cannabis harms and perceived susceptibility to cannabis harms, and perceived response and self-efficacy to prevent cannabis harms), and protective health intentions (information-seeking about cannabis health effects and having interpersonal discussions about cannabis harms with family, friends, and medical professionals). RESULTS: MANCOVA results showed no significant differences between text-only vs. pictorial attributes on protective health intentions; thus, warning conditions were controlled and analyzed using structural equation modeling (SEM). SEM results showed that attention to cannabis health warnings (text-only or pictorial) elicited higher cognitive elaboration, fear, and hope-an emotion associated with coping actions that motivate positive expectations of future events. These outcomes, in turn, were associated with greater perceived severity and susceptibility and greater perceived response efficacy, respectively. Hope, perceived severity, and perceived response and self-efficacy were independently associated with greater intentions to seek information about cannabis health effects and to discuss cannabis health harms. CONCLUSION: Attention to warnings impacted emotions, attitudes, and protective health intentions. Fear is commonly associated with health warning effects, and our results suggest that hope is also an important factor. This research contributes to understanding the effects of cannabis health warnings and can inform regulatory agencies that mandate warnings on cannabis products.

Noticing health warning labels and intentions to quit smokeless tobacco products: results from two Global Adult Tobacco Survey rounds, India.

INTRODUCTION: Health warning labels (HWLs) are one of the key strategies for tobacco control. The current study assessed the individual characteristics affecting the noticeability of HWLs and the thought of quitting smokeless tobacco (SLT) on noticing HWLs. We further estimated the temporal changes in noticeability and thought of quitting after noticing HWLs over time in India. METHODS: Data from two rounds (2009-2010 and 2016-2017) of GATS (Global Adult Tobacco Survey) from India were analysed to understand the pattern of SLT usage and estimate the relative changes in the noticeability of HWLs and the thought of quitting SLT among those who noticed HWLs. Sampling weights were used during the analysis. Multivariate binary logistic regression was used to explore the determinants for the noticeability of HWLs and encourage the intention to quit SLT after noticing the HWLs. RESULTS: About 25.9% and 20.6% of participants consumed SLT daily or non-daily in two rounds of GATS. Overall, there was a 14% relative increase in noticing the HWLs and a 20% increase in the thought of quitting in GATS-2 compared with GATS-1. The adjusted odds ratio of observing HWLs among SLT users was 1.51 times (95% confidence interval (CI), 1.44-1.58) in round 2 compared with round 1, while the odds ratio concerning the thought of quitting SLT after noticing HWLs was 1.95 times (95% CI, 1.84-2.06) in round 2 compared with round 1. CONCLUSIONS: We observe a consistent increase in the noticeability of HWLs and intentions to quit in SLT users, with significant variations across socio-demographic characteristics calling for concerted efforts. SLT being the major form of tobacco usage in India and Asian countries, HWLs alone cannot bring down the consumption rates, and it needs to be supported by strict implementation of SLT legislation for long-lasting impact.

Designing and implementing an experimental survey on knowledge and perceptions about alcohol warning labels.

OBJECTIVES: This paper describes the design and implementation of an online survey experiment to investigate the effects of alcohol warning labels on alcohol-related knowledge, risk perceptions and intentions. METHOD: The survey collected self-reported data from 14 European countries through two waves of data collection with different recruitment strategies: dissemination via social media and public health agencies was followed by paid-for Facebook ads. The latter strategy was adopted to achieve broader population representation. Post-stratification weighting was used to match the sample to population demographics. RESULTS: The survey received over 34,000 visits and resulted in a sample size of 19,601 participants with complete data on key sociodemographic characteristics. The responses in the first wave were over-representing females and higher educated people, thus the dissemination was complemented by the paid-for Facebook ads targeting more diverse populations but had higher attrition rate. CONCLUSION: Experiments can be integrated into general population surveys. Pan-European results can be achieved with limited resources and a combination of sampling methods to compensate for different biases, and statistical adjustments.
