Impact of pictorial warning labels on meat meal selection: A randomised experimental study with UK meat consumers.

Meat consumption has been linked to adverse health consequences, worsening climate change, and the risk of pandemics. Meat is however a popular food product and dissuading people from consuming meat has proven difficult. Outside the realm of meat consumption, previous research has shown that pictorial warning labels are effective at curbing tobacco smoking and reducing the consumption of sugary drinks and alcohol. The present research extends this work to hypothetical meat meal selection, using an online decision-making task to test whether people's meal choices can be influenced by pictorial warning labels focused on the health, climate, or pandemic risks associated with consuming meat. Setting quotas for age and gender to approximate a UK nationally representative sample, a total of n = 1001 adult meat consumers (aged 18+) were randomised into one of four experimental groups: health pictorial warning label, climate pictorial warning label, pandemic pictorial warning label, or control (no warning label present). All warning labels reduced the proportion of meat meals selected significantly compared to the control group, with reductions ranging from -7.4% to -10%. There were no statistically significant differences in meat meal selection between the different types of warning labels. We discuss implications for future research, policy, and practice.

Higher negative emotions in response to cigarette pictorial warning labels predict higher quit intentions among smokers.

BACKGROUND: Cigarette pictorial warning labels (PWLs) could produce stronger quit intentions than text-only warning labels (TWLs) due to greater emotional arousal. Yet, it remains unclear whether PWLs that elicit different levels of emotions produce different outcomes. To better understand the role of negative emotions in the effects of PWLs, this study developed two sets of PWLs arousing different emotional levels (high vs low) but equally high on informativeness and compared them to each other and to the current TWLs. METHODS: Adult US smokers (n=1503) were randomised to view nine high-emotion-arousing or low-emotion-arousing PWLs or TWLs. After each label, participants reported the negative emotions they felt while looking at the label. After seeing all the labels, participants reported their intentions to quit smoking. Mediation analyses tested whether message condition influenced quit intentions indirectly through negative emotions. RESULTS: Compared with TWLs, PWLs produced higher levels of negative emotions (b=0.27, SE=0.04, p<0.001). Compared with low-emotion arousing PWLs, high-emotion-arousing PWLs produced higher levels of negative emotions (b=0.24, SE=0.07, p<0.001). Higher negative emotions predicted stronger quit intentions (b=0.20, SE=0.03, p<0.001). Negative emotions mediated the effects of PWLs versus TWLs and high-emotion-arousing versus low- emotion-arousing PWLs on quit intentions. CONCLUSIONS: The results provide additional evidence for negative emotions as the mechanism through which PWLs motivate smokers to consider quitting. The findings call on the Food and Drug Administration to design and implement high-emotion-arousing cigarette warning labels.

Pictorial Warning Labels and Memory for Cigarette Health-risk Information Over Time.

BACKGROUND: Pictorial cigarette warning labels are thought to increase risk knowledge, but experimental research has not examined longer-term effects on memory for health risks named in text. PURPOSE: To investigate memory-consolidation predictions that high- versus low-emotion warnings would support better long-term memory for named cigarette health risks and to test a mediational model of warning-label effects through memory on risk perceptions and quit intentions. METHODS: A combined sample of U.S.-representative adult smokers, U.S.-representative teen smokers/vulnerable smokers, and Appalachian-representative adult smokers were randomly assigned to a warning-label condition (High-emotion pictorial, Low-emotion pictorial, Text-only) in which they were exposed four times to nine warning labels and reported emotional reactions and elaboration. Memory of warning-label risk information, smoking risk perceptions, and quit intentions were assessed immediately after exposures or 6 weeks later. RESULTS: Recall of warning-label text was low across the samples and supported memory-consolidation predictions. Specifically, immediate recall was highest for Low-emotion warnings that elicited the least emotion, but recall also declined the most over time in this condition, leaving its 6-week recall lowest; 6-week recall was similar for High-emotion and Text-only warnings. Greater recall was associated with higher risk perceptions and greater quit intentions and mediated part of warning-label effects on these important smoking outcomes. High-emotion warnings had additional non-memory-related effects on risk perceptions and quit intentions that were superior to text-only warnings. CONCLUSIONS: High- but not Low-emotion pictorial warning labels may support the Food and Drug Administration's primary goal to "effectively convey the negative health consequences of smoking."

Informing tobacco control policy in Jordan: assessing the effectiveness of pictorial warning labels on cigarette packs.

BACKGROUND: Pictorial warning labels (PWLs) deter initiation and motivate quitting. Assessing PWLs is important to track effectiveness and wear out. Jordan introduced an updated set of PWLs in 2013. This study assessed the effectiveness of the set after 2.5 years on the market. METHODS: We administered a survey in a cross-sectional sample of young adults aged 17-26 years. For convenience, respondents were recruited on university campuses. For heterogeneity, respondents were solicited from the different schools in four geographically diverse university campuses. The study compared perceptions of effectiveness surveyed in 2015 to perceptions gauged in 2010 during a pre-launch evaluation exercise. Outcomes of interest were: salience, fear evocation, adding information, and ability to motivate quitting smoking (for smokers) or deterring starting (for non-smokers). RESULTS: Results indicate awareness of the set among smokers and non-smokers, and their recall of at least one PWL message. Results also indicate effectiveness of the set: (1) 1/3 smokers who frequently saw them reported PWLs to trigger considering quitting, (2) and among both smokers and non-smokers the set in 2015 sustained ability to motivate quitting and staying smoke-free. However, results uncover erosion of salience, suggesting that the set has reached its end of life. Finally, results reveal variability in performance among PWLs; the one PWL that depicts human suffering significantly outperformed the others, and its ability to motivate was most strongly associated with its ability to evoke fear. CONCLUSION: Based on the early signs of wear-out (i.e. erosion of salience), and understanding the importance of sustaining upstream outcomes (especially fear evocation) to sustain motivation, we recommend retiring this set of PWLs and replacing it with a stronger set in line with proven standards.

Effects of pictorial warning labels depicting lesser-known and well-known risks of smoking on viewing patterns, recall, and knowledge of smoking harms.

BACKGROUND: In 2019, the Food and Drug Administration introduced 11 pictorial warning labels (PWLs) for inclusion on cigarette packages, created in compliance with court recommendations and tailored to increase knowledge of smoking harms. Several highlighted lesser-known risks of smoking. No behavioral studies have yet evaluated how risk content in PWLs impacts viewing patterns, recall, and knowledge of smoking harms. METHODS: Seventy adults who reported smoking cigarettes daily (62.9% male, 57.1% African American, mean age = 50.3, mean cigarettes per day = 14.4) completed a single-session laboratory study. They were randomized to view a set of four PWLs depicting either lesser-known or well-known risks of smoking while having eye movements recorded, then completed post-exposure recall and knowledge measures. RESULTS: Participants exposed to PWLs depicting lesser-known smoking risks viewed the text of the warning sooner and for longer than the image (p's <0.05); those exposed to PWLs depicting well-known risks viewed the image longer than text (p <0.001). PWL condition did not affect recall of text or image (p's >0.1). Those viewing lesser-known (vs. well-known) risks had greater knowledge of smoking causing lesser-known risks of bladder cancer, blindness, bloody urine, cataracts, diabetes, and head and neck cancer (p's <0.001). CONCLUSIONS: Individuals viewing PWLs depicting lesser-known (vs. well-known) smoking risks visually engaged with the PWL text more than image, had similarly high recall of PWL content, and had greater knowledge of lesser-known risks of smoking. Findings suggest including lesser-known risk information on PWLs improves overall knowledge of smoking health risks.

Impact of tobacco-pack pictorial warnings on youth and young adults: A systematic review of experimental studies.

INTRODUCTION: We conducted a systematic review of the experimental literature on the impact of tobacco-pack pictorial warning labels (PWLs) on youth and young adults. METHODS: We systematically searched computerized databases and the reference lists of relevant articles. We included studies that used an experimental protocol to assess PWLs. Studies had to report findings for youth or young adult samples (aged <30 years). Thirty-one studies met the inclusion criteria, with a total sample size of 27506. Two coders independently coded all study characteristics and outcomes. RESULTS: Twenty-eight studies experimentally evaluated PWLs for cigarette packs while three studies evaluated PWLs for smokeless tobacco packs. Generally, PWLs led to higher attention, stronger cognitive and affective reactions, more negative pack attitudes and smoking attitudes, and increased intentions not to use tobacco products compared to text warnings. PWLs were perceived to be more effective than text warnings for both cigarette packs and smokeless tobacco packs. CONCLUSIONS: The systematic review showed that PWLs on tobacco products are effective across a wide range of tobacco-related outcomes among young people. Gaps in the literature include a lack of research on tobacco initiation and cessation and a dearth of literature on non-cigarette tobacco products.

Graphic Warning Labels Affect Hypothetical Cigarette Purchasing Behavior among Smokers Living with HIV.

Cigarette pack graphic warning labels (GWLs) are associated with increased knowledge of tobacco-related harms; scant research has evaluated their effects on behavior among vulnerable populations. We used a behavioral economic approach to measure the effects of GWLs and price on hypothetical cigarette purchasing behavior among HIV-positive smokers. Participants (n = 222) completed a cigarette valuation task by making hypothetical choices between GWL cigarette packs at a fixed price ($7.00) and text-only warning label cigarette packs at increasing prices ($3.50 to $14.00; $0.25 increments). More than one-quarter (28.8%) of participants paid more to avoid GWLs. The remaining participants' purchasing decisions appear to have been driven by price: 69.8% of participants chose the cheaper pack. Across all participants, overall monetary choice value observed for GWL cigarette packs (mean = $7.75) was greater than if choice was driven exclusively by price ($7.00). Most (87.4%) preferred the text-only warning label when GWL and text-only cigarette packs were equally priced. Correlation analysis indicated GWL pack preference was associated with agreement with statements that GWLs would stop individuals from having a cigarette or facilitate thoughts about quitting. These data suggest that GWLs may influence some HIV-positive smokers in such a way that they are willing to pay more to avoid seeing GWLs.

Impact of pictorial warning labels on tobacco products among patients attending outpatient department of a dental college in Bangalore city: A cross-sectional study.

AIM: The aim of this study is to assess the knowledge, attitude, and impact of pictorial warnings present on tobacco packets among patients attending outpatient department of a dental college of Bangalore city. MATERIALS AND METHODS: A cross-sectional study was conducted among 419 patients through convenience sampling, using a structured close-ended questionnaire containing 35 questions. The participants were approached and invited to participate voluntarily. The data obtained were analyzed using descriptive statistics, Chi-square test and ANOVA. RESULTS: Mean age of the participants was 28.1 ± 7.06 years. Out of total 419 participants, 62.8% were tobacco users. About 40.6% of the participants had average knowledge and only 22.9% had positive attitude regarding the pictorial warnings. Nearly 77.9% of tobacco users had previously attempted decreased frequency of tobacco use and 63.7% had tried quitting the habit. The difference was statistically significant (P < 0.05 Chi-square test and ANOVA). CONCLUSION: The present study revealed that most of study participants have noticed the warnings on tobacco products, and most of them believe that they could understand warning labels. This study also showed that most of study participants believed that pictorial health warnings create awareness about probable health hazards of tobacco use and that these pictorial presentations on tobacco packs positively assist in reducing or quitting tobacco smoking.
