Improving Knowledge that Alcohol Can Cause Cancer is Associated with Consumer Support for Alcohol Policies: Findings from a Real-World Alcohol Labelling Study

A systematic review on the impact of alcohol warning labels

Findings on the effects of alcohol warning labels (AWLs) as a harm reduction tool have been mixed. This systematic review synthesized extant literature on the impact of AWLs on proxies of alcohol use. PsycINFO, Web of Science, PubMED, and MEDLINE databases and reference lists of eligible articles. Following PRISMA guidelines, 1,589 articles published prior to July 2020 were retrieved via database and 45 were via reference lists (961 following duplicate removal). Article titles and abstracts were screened, leaving the full text of 96 for review. The full-text review identified 77 articles meeting inclusion/exclusion criteria which are included here. Risk of bias among included studies was examined using the Evidence Project risk of bias tool. Findings fell into five categories of alcohol use proxies including knowledge/awareness, perceptions, attention, recall/recognition, attitudes/beliefs, and intentions/behavior. Real-world studies highlighted an increase in AWL awareness, alcohol-related risk perceptions (limited findings), and AWL recall/recognition post-AWL implementation; these findings have decreased over time. Conversely, findings from experimental studies were mixed. AWL content/formatting and participant sociodemographic factors also appear to influence the effectiveness of AWLs. Findings suggest conclusions differ based on the study methodology used, favoring real-world versus experimental studies. Future research should consider AWL content/formatting and participant sociodemographic factors as moderators. AWLs appear to be a promising approach for supporting more informed alcohol consumption and should be considered as one component in a comprehensive alcohol control strategy.

The potential adverse effects of minors' exposure to alcohol-related stimuli via licenced venues: A narrative review

ISSUES

Young people are particularly impressionable when it comes to forming expectations and attitudes around alcohol consumption. Any stimuli that normalise and foster positive expectations around alcohol use may increase the risk of underage alcohol consumption. Alcohol venues that market themselves as being appropriate 'family friendly' establishments for children risk exposing minors to environments that are saturated with alcohol-related stimuli. However, research examining how exposure to licenced venues affects underage people is very limited. The aim of this narrative review was to identify and synthesise relevant evidence to better understand how attending these venues might affect minors.

APPROACH

A narrative review of research published between January 2016 and November 2022 was conducted to investigate the potential effects on underage people of exposure to licenced venues and stimuli encountered in/around these venues. Examined stimuli included alcohol advertising, people consuming alcohol and alcohol outlets.

KEY FINDINGS

The reviewed literature indicates that the risk of alcohol-related harm among minors is likely to increase with greater exposure to alcohol venues due to the associated exposure to alcohol advertising, exposure to others consuming alcohol and higher outlet density. In combination, these factors are likely to normalise alcohol consumption for minors and create positive alcohol expectancies.

IMPLICATIONS AND CONCLUSION

Venues serving alcohol should be discouraged from targeting families and parents should be warned about the risks associated with taking minors to venues where alcohol is sold and consumed.

How effective are health messages/warnings in improving knowledge and awareness of alcohol-related harm? The Slovenian case on using a mobile app

BACKGROUND

Consumers generally lack access to information on alcoholic beverages, in spite of it being readily available for food and non-alcoholic beverages. Given the rights of consumers, and as with other products harmful to the population, there have been increasing calls for health warnings to be placed on alcoholic beverages, similar to those implemented on tobacco products. The aim of our research was to assess whether knowledge and awareness of the risks and harms associated with alcohol can be improved with a mobile app.

METHODS

Intervention was conducted using VKJ mobile app, which enables users to scan the barcode of an alcoholic beverage and receive feedback on its labelled alcohol content and estimated energy value. At each search, eleven different health messages/warnings about the risks and harms of alcohol are also displayed randomly, rotating on the screen. A survey was conducted before and after the intervention, to assess the knowledge and awareness of the risks and harms associated with drinking alcohol.

RESULTS

Significant differences were found for eight of the twelve tested statements. The improvement was seen to a greater extent in the group of high-risk drinkers. The results also showed that the vast majority of participants (78%) who were exposed to the health messages supported mandatory labelling of alcoholic beverages with information on ingredient listing and energy value, and 72% would like to have health warnings on alcohol products.

CONCLUSIONS

The use of a mobile app can be an option to improve knowledge and raise awareness of the risks and harms related to alcohol.

Public awareness of the alcohol-cancer link in the EU and UK: a scoping review

BACKGROUND

Alcohol increases cancer risk, but less is known about public awareness of this link. This scoping review summarizes recent findings on the public awareness of alcohol as a cancer risk factor in European Union and UK.

METHODS

Four databases (Web of Science, MEDLINE, PsycInfo, CINAHL) were searched for papers containing data on awareness of alcohol as cancer risk factor in EU or UK published between January 2017 and December 2022, and complemented with grey literature searches.

RESULTS

In total, 45 studies were included covering 18 EU countries (Austria, Belgium, Cyprus, Czechia, Denmark, Finland, France, Germany, Hungary, Ireland, Italy, Netherlands, Poland, Romania, Slovakia, Slovenia, Spain, Sweden) and UK, presenting data collected between 2009 and 2022. Studies covered general population (17 studied a nationally representative sample), women, health professionals, patients and young people. Awareness of alcohol causing cancer in general was higher and studied more often than awareness of alcohol's impact on specific cancers. Among the EU general population, awareness of the link between alcohol and breast cancer ranged between 10% and 20%, head and neck cancer 15-25%, colorectal and oesophagus cancer 15-45% and liver cancer 40%. Awareness was higher among young people and specialized health professions and lower among women (the latter specifically for the breast cancer).

CONCLUSIONS

While awareness rates varied depending on the exact question wording, many studies showed low awareness of the alcohol-cancer link, especially for specific types such as breast and colon cancer. Public should be better informed about alcohol consumption-related cancer risk.

Why Canadians deserve to have mandated health and standard drink information labels on alcohol containers

To reduce deaths, morbidity, and social problems from alcohol in Canada, a multi-dimensional robust response is needed, including a comprehensive alcohol control strategy at the provincial, territorial, and federal levels. Alcohol container labels with health and standard drink information are an essential component of this strategy. This commentary provides a rationale for the mandatory labelling of all alcohol products, summarizes Canadian initiatives to date to legislate alcohol container warning labels, and addresses myths and misconceptions about labels. Canadians deserve direct, accessible information about (1) the inherent health risks associated with alcohol consumption, (2) the number of standard drinks per container and volume of a standard drink, and (3) guidance for preventing or reducing consumption-related health risks. Enhanced health labels on alcohol containers are long overdue.

How Do Young Adult Drinkers React to Varied Alcohol Warning Formats and Contents? An Exploratory Study in France

Research on alcohol warnings has increased in the last decade, providing key evidence to governments on warning format and contents. The bulk of this research, however, has been conducted in Anglosphere countries, whereas fewer studies have focused on other countries which have high per capita alcohol consumption, and where the high social acceptability of drinking is liable to affect how people accept and react to prevention measures. Since France has one of the highest per capita alcohol consumption rates in the world according to the World Health Organization (WHO), we therefore explore how young adults in France react to warnings on alcoholic beverage advertisements. We conducted 25 in-depth interviews, in 2017, with 18-25-year-old drinkers in France. Respondents were asked open-ended questions on the perceived impact of various warning contents (i.e., on health risk, social-cost risk, and on short- vs. long-term risk) and formats (text only vs. larger text combined with colored pictograms). Warnings that targeted youth-relevant risks (i.e., road accidents or sexual assault) were considered to be the most meaningful and credible, although warnings communicating longer term risks (i.e., brain, cancer) were also thought to be influential. Less familiar risks, such as marketing manipulation and calorie intake, elicited the most negative reactions. Larger text-and-pictogram warnings were considered to be the most effective format in capturing attention and increasing awareness. Regardless of format and content, however, these warnings were not perceived as effective for decreasing alcohol consumption.

Evaluating an alcohol harm-reduction campaign advising drinkers of the alcohol-cancer link

INTRODUCTION

Public awareness of the alcohol-cancer link is low. Provision of this information could reduce alcohol consumption and related harms. The Spread campaign is a multi-media education campaign implemented in Western Australia to inform people about the carcinogenic properties of alcohol and associated harms. The aims of the present study were to (i) examine attitudinal and behavioural outcomes of the Spread campaign and (ii) identify demographic and drinking status factors associated with enactment of harm-reduction behaviours resulting from exposure.

METHOD

A cross sectional survey of Western Australian drinkers (consumed alcohol at least a few times in the previous 12 months, n = 760) examined campaign recognition, campaign perceptions, and behaviours resulting from campaign exposure. Chi-square analyses and a generalised linear model were used to identify demographic and alcohol-related factors associated with behavioural outcomes.

RESULTS

Around two-thirds of respondents recognised the campaign (65%), and of these, 22% reported successfully reducing how often or how much they drank due to seeing the campaign. Three quarters (73%) of all respondents considered the campaign message about the alcohol-cancer link to be believable. Respondents drinking at levels above the Australian guideline were less likely to have positive perceptions of the campaign than those complying with the guideline, but were more likely to report enacting the assessed harm-reduction behaviours as a result of campaign exposure.

DISCUSSION AND CONCLUSION

The results suggest that provision of information about the alcohol-cancer link has the potential to motivate reduced alcohol consumption. Implementing such campaigns could constitute an effective alcohol harm-reduction strategy.

Improving alcohol health literacy and reducing alcohol consumption: recommendations for Germany

BACKGROUND

Although the detrimental health effects of alcohol are well established, consumption levels are high in many high-income countries such as Germany. Improving alcohol health literacy presents an integrated approach to alcohol prevention and an important complement to alcohol policy. Our aim was to identify and prioritize measures to enhance alcohol health literacy and hence to reduce alcohol consumption, using Germany as an example.

METHODS

A series of recommendations for improving alcohol health literacy were derived from a review of the literature and subsequently rated by five experts. Recommendations were rated according to their likely impact on enhancing (a) alcohol health literacy and (b) reducing alcohol consumption. Inter-rater agreement was assessed using a two-way intra-class correlation coefficient (ICC).

RESULTS

Eleven recommendations were established for three areas of action: (1) education and information, (2) health care system, and (3) alcohol control policy. Education and information measures were rated high to increase alcohol health literacy but low to their impact on alcohol consumption, while this pattern was reversed for alcohol control policies. The ratings showed good agreement (ICC: 0.85-0.88).

CONCLUSIONS

Improving alcohol health literacy and reducing alcohol consumption should be considered complementary and become part of a comprehensive alcohol strategy to curb the health, social, and economic burden of alcohol.

Exploring correlates of support for restricting breast cancer awareness marketing on alcohol containers among women

BACKGROUND

Although alcohol consumption increases breast cancer risk, some alcohol products include breast cancer awareness marketing (i.e., pink ribbons) on alcohol containers, which poses a contradiction. Some researchers and advocacy groups have called for restrictions on use of the pink ribbon and other breast cancer awareness marketing on alcohol products. This exploratory study aimed to describe individual and behavioral correlates (age, knowledge, attitudes, purchase intention) of reported support for potential policy restrictions of pink ribbon labeling on alcohol containers.

METHODS

The study sample was drawn from the Prolific crowd-sourced research platform in September 2020. Eligible participants included U.S. women aged 21+ years. The primary outcome was policy position for restrictions on pink ribbon labeling on alcohol containers, coded as support, neutral, or oppose. The association between pink ribbon labeling attitudes and support or opposition (vs neutral) was examined using multinomial logistic regression. Covariates were 1) knowledge of the alcohol-cancer link; 2) likelihood of buying an alcohol product with pink ribbon labeling; and 3) age. Models were used to calculate adjusted predicted probabilities for support, oppose, and neutral.

RESULTS

The analytic sample included 511 women. Overall, 46% of women opposed, 34% were neutral, and 20% supported restricting pink ribbon labeling on alcohol containers. Controlling for all covariates, women who reported that wine increases cancer risk had the highest probability of opposing restrictions on pink ribbon labeling (56.4% [95%CI: 48.1%-64.8%]). Women who reported wine had no effect on cancer risk had the highest probability of being neutral about restrictions on pink ribbon labeling (45.5% [95% CI: 35.7%-55.3%]). Across levels of knowledge about the alcohol-cancer risk association, as favorable attitudes toward pink ribbon labeling increased, the probability of policy opposition increased and the probability of being policy neutral decreased.

CONCLUSION

Findings from this study suggest women's favorable attitudes toward pink ribbon labeling on alcohol containers are a stronger predictor of support or opposition for restrictions on pink ribbon labeling than knowledge of the alcohol-cancer link. Future research could examine whether pink ribbon labeling may interact with potential or current health warnings on alcohol containers.

Prevention of the Pro-Aggressive Effects of Ethanol-Intoxicated Mice by Schisandrin B

Excessive alcohol consumption can lead to serious health complications, with liver and neurological complications being the most important. In Western nations, alcoholic liver disease accounts for 50% of mortality from end-stage liver disease and is the second most common cause of liver transplants. In addition to direct damage, hepatic encephalopathy may also arise from alcohol consumption. However, effective treatment for liver disease, as well as neurological injury, is still lacking today; therefore, finding an efficacious alternative is urgently needed. In the current study, the preventive and therapeutic effects of Schisandrin B (Sch B) against ethanol-induced liver and brain injuries were investigated. By using two treatment models, our findings indicated that Sch B can effectively prevent and ameliorate alcoholic liver diseases, such as resolving liver injuries, lipid deposition, inflammasome activation, and fibrosis. Moreover, Sch B reverses brain damage and improves the neurological function of ethanol-treated mice. Therefore, Sch B may serve as a potential treatment option for liver diseases, as well as subsequential brain injuries. Furthermore, Sch B may be useful in preventive drug therapy against alcohol-related diseases.

Do Beliefs about Alcohol and Cancer Risk Vary by Alcoholic Beverage Type and Heart Disease Risk Beliefs?

BACKGROUND

Alcohol is a leading risk factor for cancer, yet awareness of the alcohol-cancer link is low. Awareness may be influenced by perceptions of potential health benefits of alcohol consumption or certain alcoholic beverage types. The purpose of this study was to estimate awareness of the alcohol-cancer link by beverage type and to examine the relationship between this awareness and concomitant beliefs about alcohol and heart disease risk.

METHODS

We analyzed data from the 2020 Health Information National Trends Survey 5 Cycle 4, a nationally representative survey of U.S. adults.

RESULTS

Awareness of the alcohol-cancer link was highest for liquor (31.2%), followed by beer (24.9%) and wine (20.3%). More U.S. adults believed wine (10.3%) decreased cancer risk, compared with beer (2.2%) and liquor (1.7%). Most U.S. adults (>50%) reported not knowing how these beverages affected cancer risk. U.S. adults believing alcoholic beverages increased heart disease risk had higher adjusted predicted probabilities of being aware of the alcohol-cancer link (wine: 58.6%; beer: 52.4%; liquor: 59.4%) compared with those unsure (wine: 6.0%; beer: 8.6%; liquor: 13.2%), or believing alcoholic beverages reduced (wine: 16.2%; beer: 21.6%; liquor: 23.8%) or had no effect on heart disease risk (wine: 10.2%; beer: 12.0%; liquor: 16.9%).

CONCLUSIONS

Awareness of the alcohol-cancer link was low, varied by beverage type, and was higher among those recognizing that alcohol use increased heart disease risk.

IMPACT

These findings underscore the need to educate U.S. adults about the alcohol-cancer link, including raising awareness that drinking all alcoholic beverage types increases cancer risk. See related commentary by Hay et al., p. 9.

Support for cancer prevention public health policies: results from a nationally representative sample of residents in the United States

Assessing public support of health policies designed to reduce cancer risk is important for policy implementation. This study aimed to identify support for cancer prevention policies and factors associated with support. Data were obtained from the Health Information National Trends Survey. Support for three types of cancer prevention policies were evaluated: tobacco, alcohol, and junk food regulations. Linear and logistic regression analyses were employed to assess the relationship between support for the different types of policies and sociodemographic, lifestyle behaviors, and cancer beliefs. Certain policies, such as providing warning labels on cigarettes (69.9% support) and requiring specific health warnings on alcohol containers (65.1% support), were popular. Banning outdoor advertising of alcohol was not popular (34.4% support). There were individual differences associated with policy support. For example, respondents who were 75 years or older (B = 0.61, p < .001) or female (B = 0.14, p < .008) were more likely to support tobacco polices compared to their counterparts (i.e., younger or male). Respondents who identified as politically conservative (B = -0.20, p < .004) or those who endorsed high cancer fatalistic beliefs (e.g., there's not much you can do to lower your chances of getting cancer, B = -0.07, p < .012) were less likely to support alcohol policies compared to those who were liberal or had lower cancer fatalistic beliefs. Generally, support was high for most policy questions. However, support varied by different individual factors. The findings also highlight that there may be opportunities to increase understanding and awareness about cancer prevention policies, especially among some segments of the population.

Burden of diseases and injuries attributable to alcohol consumption in the Middle East and North Africa region, 1990-2019

Alcohol consumption is associated with a number of diseases and injuries, including cardiovascular diseases, cancers, mental and neurological disorders, as well as transport-related injuries. This article reports the alcohol-attributable burden of diseases and injuries at the regional and national levels in the Middle East and North Africa (MENA) region between 1990 and 2019, by sex, age, underlying cause, and Socio-demographic Index (SDI). The regional deaths and disability-adjusted life-years (DALYs) attributable to alcohol consumption were reported for the MENA region, between 1990 and 2019, using the methodological framework and analytical strategies adopted by the Global Burden of Disease (GBD) study 2019. The estimates were all reported as counts, population-attributable fractions, and age-standardised rates per 100,000 population, along with their corresponding 95% uncertainty intervals (UIs). Also, the average annual percentage changes were used to represent the trends of age-standardised rates. In 2019, there were an estimated 22.0 thousand deaths (95% UI: 16.1-29.4) and 1.1 million DALYs (0.8-1.3) attributable to alcohol consumption in the MENA region. The number of DALYs attributable to alcohol consumption were much higher in men (878.0 thousand, 691.4-1104.8) than among women (181.8, 138.6-232.0). The overall age-standardised death and DALY rates attributable to alcohol consumption decreased by 34.5% (13.2-48.3) and 31.9% (16.9-42.5), respectively, over the study period. Egypt (10.1 [5.7-16.6]) and Kuwait (1.1 [0.8-1.5]) had the highest and lowest age-standardised death rates attributable to alcohol consumption, respectively. In 2019, the number of deaths and DALYs in the MENA region were highest in those aged 60-64 and 50-54 years, respectively. A negative association was observed between a country's SDI and their corresponding age-standardised DALY rates over the period 1990 to 2019. Digestive diseases were the main contributor to the alcohol-attributable burden. Over 1990-2019, the regional deaths and DALYs of diseases and injuries attributable to alcohol consumption decreased with AAPC of - 1.45 (- 1.78 to - 1.12) and - 1.31 (- 1.46 to - 1.15), respectively. The death and DALY rates attributable to alcohol consumption in the MENA region have decreased over the past three decades. Further decreases can be facilitated by implementing country-level policies and increasing public awareness.

Liver Transplant Recipients Speak Out on Public Awareness and Education Surrounding Alcohol-Related Health Effects: A Survey Study

BACKGROUND

Compared to other recreational substances in Canada, alcohol consumption incurs the highest healthcare costs. Liver transplant recipients are unique stakeholders as members of the general public with lived experiences of liver disease. We sought to explore their perspectives on the current state of public education on alcohol-related health effects.

METHODS

The most recent 400 liver transplant recipients at Vancouver General Hospital, Canada, were invited to participate in an anonymous online survey on alcohol-related health effects by mail, email, and phone.

RESULTS

Of 372 contacted patients, 212 (57%) completed the survey. Most patients were between 60-79 years, 63% were male, and 69% were Caucasian. The most common liver conditions leading to transplant were viral hepatitis (33%), alcohol-related liver disease (16%), autoimmune liver disease (14%), and non-alcoholic fatty liver disease (15%). Most patients knew that alcohol leads to liver failure (85%), but fewer knew about alcohol leading to cancer (54%), heart disease (50%), and damage to other organs (58%). Most common sources of information included public media (61%), family and friends (52%), and physicians (49%), with narrative comments about learning of alcohol-related health effects after liver diagnosis. Most patients believed that public health education at a middle/high school level would have long-term efficacy (72%) compared to health warning labels (33%) and safety messaging in commercials (39%). Current public education was felt to be adequate by only 20% of patients and 73% of patients supported health warning labels.

CONCLUSIONS

Liver transplant patients reported a high, but not universal, awareness of alcohol-related health effects. A majority thought that current public health efforts were inadequate; it is critical to implement public health interventions to ensure consumers are able to make an informed decision on alcohol consumption.

Awareness of Alcohol and Cancer Risk and the California Proposition 65 Warning Sign Updates: A Natural Experiment

In 1986, California enacted Proposition 65 (P65), requiring businesses to display warning signs informing consumers that specific chemicals and alcohol exposure increase the risk of cancer and reproductive harm. In 2018, the P65 alcohol warning signs were updated to include an informational P65 website link, and the update was associated with media coverage and increased enforcement of warning requirements. This study examines knowledge of the association between alcohol use and cancer risk in California compared to the rest of the US before and after the 2018 P65 update. We analyzed state-level data on alcohol and cancer knowledge from the Health Information National Trends Survey from 2017 (n = 3285), 2019 (n = 5438), and 2020 (n = 3865). We performed multinomial logistic regressions to examine knowledge levels by survey year and location (California vs. all other states) and reported the predicted marginals of knowledge by survey year and location. The adjusted prevalence of respondents who reported an association between alcohol and cancer risk was higher in California (41.6%) than the remaining states (34.1%) (p = 0.04). However, knowledge levels decreased significantly over survey years, and there was no evidence for an effect of the P65 update on knowledge in California compared to other states based on the testing of an interaction between state and year (p = 0.32). The 1986 warning signs may have had an enduring effect on awareness, though the update, so far, has not. Further efforts are needed to determine how to increase alcohol and cancer knowledge to address the burden of alcohol-attributable cancers.

Alcohol Health Warning Labels: A Rapid Review with Action Recommendations

A rapid review of research on health warning labels located on alcohol containers (AWLs) was conducted. Using five search engines (Embase, Medline, Pubmed, Scopus, Psyinfo), 2975 non-duplicate citations were identified between the inception date of the search engine and April 2021. Of those, 382 articles were examined and retrieved. We selected 122 research papers for analysis and narrative information extraction, focusing on population foci, study design, and main outcomes. Research included public opinion studies, surveys of post-AWL implementation, on-line and in-person experiments and real-world quasi-experiments. Many studies focused on the effects of the 1989 United States Alcoholic Beverage Labeling Act on perceptions, intentions and behavior. Others focused on Australia, Canada, the United Kingdom, England or Scotland, Italy and France. There was substantial variation in the design of the studies, ranging from small-scale focus groups to on-line surveys with large samples. Over time, evidence has been emerging on label design components, such as large size, combination of text and image, and specific health messaging, that is likely to have some desired impact on knowledge, awareness of risk and even the drinking behavior of those who see the AWLs. This body of evidence provides guidance to policy-makers, and national and regional authorities, and recommendations are offered for discussion and consideration.

A Narrative Review of the Efficacy and Design of Safety Labels on Tobacco Products to Promote the Use of Safety Labels on Alcohol Products in Canada

Alcohol is consumed by approximately three-quarters of Canadians. Alcohol causes acquired liver disease, increases the risk of cancer, has detrimental effects on mental health, and leads to adverse pregnancy outcomes. Alcohol-related morbidity and mortality are high, and urgent public health measures are warranted to prevent and control these. Tobacco safety labels have been shown in numerous studies to reduce tobacco consumption. Much can be learned from the design of tobacco safety labels in creating promising alcohol safety labels that can possibly help reduce alcohol consumption. The aim of this paper is to review the efficacy of tobacco safety labels in reducing tobacco consumption and the design of tobacco safety labels and to propose a promising design for alcohol safety labels based on our findings. English peer-reviewed papers published in western countries since 2000 were searched on PubMed and Google Scholar. Keywords and synonyms were used to search pertinent papers, which were subsequently screened by title and abstract and fully reviewed if relevant. Findings from studies comparing designs of safety labels on alcohol and tobacco products are similar. Graphics, higher emotion content, and greater size are associated with greater attention, awareness, negative emotions, intention to quit, and reduction in consumption. Mixed results are found for testimonials containing safety labels on tobacco products. It is unclear whether testimonials on alcohol safety labels reduce alcohol consumption or not. Safety labels with specific information, such as tobacco-related costs and alcohol-related cancer risks, are more effective in reducing tobacco consumption. In conclusion, preliminary alcohol safety labels show promise. Large safety labels with graphics and high emotional content appear to be most effective and may reduce alcohol consumption.

Awareness of Alcohol as a Carcinogen and Support for Alcohol Control Policies

INTRODUCTION

Alcohol use increases cancer risk, yet awareness of this association is low. Alcohol control policies have the potential to reduce alcohol-caused cancer morbidity and mortality. Research outside the U.S. has found awareness of the alcohol-cancer link to be associated with support for alcohol control policies. The purpose of this study is to estimate the prevalence of support for 3 communication-focused alcohol policies and examine how awareness of the alcohol-cancer link and drinking status are associated with policy support among U.S. residents.

METHODS

Investigators analyzed data from the 2020 Health Information National Trends Survey 5 Cycle 4. Analyses were performed in 2021. The proportion of Americans who supported banning outdoor alcohol advertising and adding warning labels and drinking guidelines to alcohol containers was estimated. Weighted multivariable logistic regression was used to examine how awareness of the alcohol-cancer link and drinking status were associated with policy support.

RESULTS

Most Americans supported adding warning labels (65.1%) and drinking guidelines (63.9%), whereas only 34.4% supported banning outdoor alcohol advertising. Americans reporting that alcohol had no effect/decreased cancer risk had lower odds of support for advertising ban (OR=0.56), warning labels (OR=0.43), and guidelines (OR=0.46) than Americans aware of the alcohol-cancer link. Moreover, heavier drinkers had lower odds of support for advertising ban (OR=0.41), warning labels (OR=0.59), and guidelines (OR=0.60) than nondrinkers.

CONCLUSIONS

Awareness of the alcohol-cancer link was associated with policy support. Increasing public awareness of the alcohol-cancer link may increase support for alcohol control policies.

Alcohol and Cancer: Existing Knowledge and Evidence Gaps across the Cancer Continuum

Alcoholic beverages are carcinogenic to humans. Globally, an estimated 4.1% of new cancer cases in 2020 were attributable to alcoholic beverages. However, the full cancer burden due to alcohol is uncertain because for many cancer (sub)types, associations remain inconclusive. Additionally, associations of consumption with therapeutic response, disease progression, and long-term cancer outcomes are not fully understood, public awareness of the alcohol-cancer link is low, and the interrelationships of alcohol control regulations and cancer risk are unclear. In December 2020, the U.S. NCI convened a workshop and public webinar that brought together a panel of scientific experts to review what is known about and identify knowledge gaps regarding alcohol and cancer. Examples of gaps identified include: (i) associations of alcohol consumption patterns across the life course with cancer risk; (ii) alcohol's systemic carcinogenic effects; (iii) alcohol's influence on treatment efficacy, patient-reported outcomes, and long-term prognosis; (iv) communication strategies to increase awareness of the alcohol-cancer link; and (v) the impact of alcohol control policies to reduce consumption on cancer incidence and mortality. Interdisciplinary research and implementation efforts are needed to increase relevant knowledge, and to develop effective interventions focused on improving awareness, and reducing harmful consumption to decrease the alcohol-related cancer burden.

Health warning labels and alcohol selection: a randomised controlled experiment in a naturalistic shopping laboratory

BACKGROUND AND AIMS

Health warning labels (HWLs) on tobacco products reduce smoking. There is an absence of evidence concerning the impact of alcohol HWLs on selection or purchasing in naturalistic settings. Using a commercial-standard naturalistic shopping laboratory, this study aimed to estimate the impact on selection of alcoholic drinks of HWLs describing adverse health consequences of excessive alcohol consumption.

DESIGN

A between-subjects randomised experiment with three groups was conducted: group 1: image-and-text HWL; group 2: text-only HWL; group 3: no HWL.

SETTING

A commercial-standard naturalistic shopping laboratory in the United Kingdom.

PARTICIPANTS

Adults (n = 399, 55% female) over the age of 18 years, who purchased beer or wine weekly to drink at home.

INTERVENTIONS

Participants were randomised to one of three groups varying in the HWL displayed on the packaging of the alcoholic drinks: (i) image-and-text HWL (n = 135); (ii) text-only HWL (n = 129); (iii) no HWL (n = 135). Participants completed a shopping task, selecting items from a range of alcoholic and non-alcoholic drinks, and snacks.

MEASUREMENT

The primary outcome was the proportion of alcoholic drinks selected. Secondary outcomes included HWL ratings on negative emotional arousal and label acceptability.

FINDINGS

There was no clear evidence of a difference in the HWL groups for the percentage of drinks selected that were alcoholic compared to no HWL (44%): image-and-text HWL: 46% (odds ratio [OR] = 1.08, 95% confidence interval [CI] = 0.82, 1.42); text-only HWL: 41% (OR = 0.87, 95% CI = 0.67, 1.14). Concordant with there being no difference between groups, there was extreme evidence in favour of the null hypothesis (Bayes factor [BF] < 0.01). Negative emotional arousal was higher (P < 0.001) and acceptability lower (P < 0.001) in the image-and-text HWL group, compared to the text-only HWL group.

CONCLUSIONS

In a naturalistic shopping laboratory, there was no evidence that health warning labels describing the adverse health consequences of excessive alcohol consumption changed selection behaviour.

Media representations of opposition to the 'junk food advertising ban' on the Transport for London (TfL) network: A thematic content analysis of UK news and trade press

BACKGROUND

Advertising of less healthy foods and drinks is hypothesised to be associated with obesity in adults and children. In February 2019, Transport for London implemented restrictions on advertisements for foods and beverages high in fat, salt or sugar across its network as part of a city-wide strategy to tackle childhood obesity. The policy was extensively debated in the press. This paper identifies arguments for and against the restrictions. Focusing on arguments against the restrictions, it then goes on to deconstruct the discursive strategies underpinning them.

METHODS

A qualitative thematic content analysis of media coverage of the restrictions (the 'ban') in UK newspapers and trade press was followed by a document analysis of arguments against the ban. A search period of March 1, 2018 to May 31, 2019 covered: (i) the launch of the public consultation on the ban in May 2018; (ii) the announcement of the ban in November 2018; and (iii) its implementation in February 2019. A systematic search of printed and online publications in English distributed in the UK or published on UK-specific websites identified 152 articles.

RESULTS

Arguments in favour of the ban focused on inequalities and childhood obesity. Arguments against the ban centred on two claims: that childhood obesity was not the 'right' priority; and that an advertising ban was not an effective way to address childhood obesity. These claims were justified via three discursive approaches: (i) claiming more 'important' priorities for action; (ii) disputing the science behind the ban; (iii) emphasising potential financial costs of the ban.

CONCLUSION

The discursive tactics used in media sources to argue against the ban draw on frames widely used by unhealthy commodities industries in response to structural public health interventions. Our analyses highlight the need for interventions to be framed in ways that can pre-emptively counter common criticisms.

Nature and Potential Impact of Alcohol Health Warning Labels: A Scoping Review

Alcohol is toxic to human health. In addition to providing nutritional information, labels on alcohol products can be used to communicate warnings on alcohol-related harms to consumers. This scoping review examined novel or enhanced health warning labels to assess the current state of the research and the key studied characteristics of labels, along with their impact on the studied outcomes. Four databases (Web of Science, MEDLINE, PsycInfo, CINAHL) were searched between January 2010 and April 2021, and 27 papers were included in the review. The results found that most studies were undertaken in English-speaking populations, with the majority conducted online or in the laboratory setting as opposed to the real world. Seventy percent of the papers included at least one cancer-related message, in most instances referring either to cancer in general or to bowel cancer. Evidence from the only real-world long-term labelling intervention demonstrated that alcohol health warning labels designed to be visible and contain novel and specific information have the potential to be part of an effective labelling strategy. Alcohol health warning labels should be seen as tools to raise awareness on alcohol-related risks, being part of wider alcohol policy approaches.

Government Options to Reduce the Impact of Alcohol on Human Health: Obstacles to Effective Policy Implementation

Evidence for effective government policies to reduce exposure to alcohol's carcinogenic and hepatoxic effects has strengthened in recent decades. Policies with the strongest evidence involve reducing the affordability, availability and cultural acceptability of alcohol. However, policies that reduce population consumption compete with powerful commercial vested interests. This paper draws on the Canadian Alcohol Policy Evaluation (CAPE), a formal assessment of effective government action on alcohol across Canadian jurisdictions. It also draws on alcohol policy case studies elsewhere involving attempts to introduce minimum unit pricing and cancer warning labels on alcohol containers. Canadian governments collectively received a failing grade (F) for alcohol policy implementation during the most recent CAPE assessment in 2017. However, had the best practices observed in any one jurisdiction been implemented consistently, Canada would have received an A grade. Resistance to effective alcohol policies is due to (1) lack of public awareness of both need and effectiveness, (2) a lack of government regulatory mechanisms to implement effective policies, (3) alcohol industry lobbying, and (4) a failure from the public health community to promote specific and feasible actions as opposed to general principles, e.g., 'increased prices' or 'reduced affordability'. There is enormous untapped potential in most countries for the implementation of proven strategies to reduce alcohol-related harm. While alcohol policies have weakened in many countries during the COVID-19 pandemic, societies may now also be more accepting of public health-inspired policies with proven effectiveness and potential economic benefits.

Global burden of cancer in 2020 attributable to alcohol consumption: a population-based study

BACKGROUND

Alcohol use is causally linked to multiple cancers. We present global, regional, and national estimates of alcohol-attributable cancer burden in 2020 to inform alcohol policy and cancer control across different settings globally.

METHODS

In this population-based study, population attributable fractions (PAFs) calculated using a theoretical minimum-risk exposure of lifetime abstention and 2010 alcohol consumption estimates from the Global Information System on Alcohol and Health (assuming a 10-year latency period between alcohol consumption and cancer diagnosis), combined with corresponding relative risk estimates from systematic literature reviews as part of the WCRF Continuous Update Project, were applied to cancer incidence data from GLOBOCAN 2020 to estimate new cancer cases attributable to alcohol. We also calculated the contribution of moderate (<20 g per day), risky (20-60 g per day), and heavy (>60 g per day) drinking to the total alcohol-attributable cancer burden, as well as the contribution by 10 g per day increment (up to a maximum of 150 g). 95% uncertainty intervals (UIs) were estimated using a Monte Carlo-like approach.

FINDINGS

Globally, an estimated 741 300 (95% UI 558 500-951 200), or 4·1% (3·1-5·3), of all new cases of cancer in 2020 were attributable to alcohol consumption. Males accounted for 568 700 (76·7%; 95% UI 422 500-731 100) of total alcohol-attributable cancer cases, and cancers of the oesophagus (189 700 cases [110 900-274 600]), liver (154 700 cases [43 700-281 500]), and breast (98 300 cases [68 200-130 500]) contributed the most cases. PAFs were lowest in northern Africa (0·3% [95% UI 0·1-3·3]) and western Asia (0·7% [0·5-1·2]), and highest in eastern Asia (5·7% [3·6-7·9]) and central and eastern Europe (5·6% [4·6-6·6]). The largest burden of alcohol-attributable cancers was represented by heavy drinking (346 400 [46·7%; 95% UI 227 900-489 400] cases) and risky drinking (291 800 [39·4%; 227 700-333 100] cases), whereas moderate drinking contributed 103 100 (13·9%; 82 600-207 200) cases, and drinking up to 10 g per day contributed 41 300 (35 400-145 800) cases.

INTERPRETATION

Our findings highlight the need for effective policy and interventions to increase awareness of cancer risks associated with alcohol use and decrease overall alcohol consumption to prevent the burden of alcohol-attributable cancers.

Effects of alcohol warning labels on alcohol-related cognitions among German adolescents: A factorial experiment

There is evidence that alcohol warning labels (AWL) can have preventive effects on alcohol-related cognitions and behavior, but it is less clear how children and adolescents react to AWL. A total of 9260 German students aged 10-17 participated in a three-factorial experiment, embedded in a health survey. The first experimental factor was the position of the AWL on the questionnaire (before vs. after alcohol items). The second factor was the type of AWL (text only vs. text plus picture). The third factor was the content of the AWL (one out of a pool of ten). Dependent variables were knowledge about alcohol-related risks, self-reports of alcohol use, and negative emotions. Regression analyses revealed that exposure to an AWL significantly increased knowledge about alcohol-related risks. AWL exposure did not influence self-reports of alcohol use in the total sample, but a significant interaction for PositionXAge indicated that older students (15+ years) less frequently reported lifetime (79.8% vs. 84.2%) and current (50.5% vs. 56.6%) use of alcohol if they were exposed to an AWL. Overall, text-only AWL elicited less negative emotions than text-and-picture based AWL. The experiment indicates that exposure to an AWL affected alcohol-related cognitions of children and adolescents. This was true for both, text-based or picture-and-text-based labels. Pictorial messages seem to be more potent to elicit emotions, at least for recipients that already have experience with alcohol use. Future research needs to further explore the long-term effects of repeated exposure to the same message contents.

Strategies for engaging policy stakeholders to translate research knowledge into practice more effectively: Lessons learned from the Canadian Alcohol Policy Evaluation project

INTRODUCTION

Evidence-based alcohol policies have the potential to reduce a wide range of related harms. Yet, barriers to adoption and implementation within governments often exist. Engaging relevant stakeholders may be an effective way to identify and address potential challenges thereby increasing reach and uptake of policy evaluation research and strengthening jurisdictional responses to alcohol harms.

METHODS

As part of the 2019 Canadian Alcohol Policy Evaluation project, we conducted interviews with government stakeholders across alcohol-related sectors prior to a second round of researcher-led policy assessments in Canada's 13 provinces and territories. Stakeholders were asked for feedback on the design and impact of an earlier policy assessment in 2013 and for recommendations to improve the design and dissemination strategy for the next iteration. Content analysis was used to identify ways of improving stakeholder engagement.

RESULTS

We interviewed 25 stakeholders across 12 of Canada's 13 jurisdictions, including representatives from government health ministries and from alcohol regulation, distribution and finance departments. In providing feedback on our stakeholder engagement strategy, participants highlighted the importance of maintaining ongoing contact; presenting results in accessible online formats; providing advance notice of results; and offering jurisdiction-specific webinars.

DISCUSSION AND CONCLUSIONS

This study offers important insight into the engagement preferences of government stakeholders involved in the health, regulation, distribution and financial aspects of alcohol control policy. Findings suggest that seeking input from stakeholders as part of conducting evaluation research is warranted; increasing the relevance, reach and uptake of results. Specific stakeholder engagement strategies are outlined.

Are people aware of the link between alcohol and different types of Cancer?

BACKGROUND

Alcohol consumption is causally linked to several different types of cancer, including breast, liver, and colorectal cancer. While prior studies have found low awareness of the overall alcohol-cancer link, few have examined how awareness differs for each type of cancer. Greater awareness of risks associated with alcohol use may be a key factor in reducing alcohol-related cancer incidence.

METHODS

We surveyed 1759 people of legal drinking age at the 2019 Minnesota State Fair. We used multivariable generalized linear models and linear regression models with robust standard errors to investigate factors associated with alcohol-cancer risk awareness. Models were fit examining predictors of overall awareness of alcohol as a risk factor for cancer, and prevalence of awareness of alcohol as a risk factor for specific types of cancer.

RESULTS

Prevalence of awareness varied by cancer type, with awareness of alcohol causing liver cancer having the highest prevalence (92%) and awareness of alcohol causing breast cancer having the lowest prevalence (38%). Factors associated with awareness of alcohol-cancer risk differed by type of cancer.

CONCLUSIONS

In general, awareness of the risk of alcohol for certain types of cancer was low to moderate, reflecting a need to inform people not only that alcohol increases risk of cancer, but which types of cancer are most highly associated alcohol.

Understanding the effectiveness of advertisements about the long-term harms of alcohol and low-risk drinking guidelines: A mediation analysis

RATIONALE

Many people overestimate the amount of alcohol that increases their risk of harm and so may not perceive any need to change their drinking behaviour. Several countries have developed low-risk drinking guidelines, yet awareness of these guidelines remains low. Furthermore, mass media campaigns about alcohol-related harms may have limited impact if people do not perceive their current consumption as potentially harmful. Integrating drinking guidelines into media campaigns about alcohol's harms can concurrently provide drinkers with information about low-risk drinking levels and compelling reasons to comply.

OBJECTIVE

Our aim was to build understanding of the effectiveness of messages about the long-term harms of drinking and low-risk drinking guidelines, by testing the mediating effects of estimates of harmful drinking levels and attitudes towards drinking alcohol on subsequent intentions and behaviours.

METHOD

In an online experiment conducted in 2016, n = 1156 Australian adult monthly drinkers were randomly assigned to view advertisements for non-alcohol products (NON-ALC; control), advertisements featuring long-term harms of alcohol (LTH), or LTH advertisements plus a guideline message (LTH + G). Immediately following exposure, we measured estimates of harmful drinking levels and attitudes towards drinking alcohol. One week later, we measured intentions to drink less and behavioural compliance with the guideline.

RESULTS

Compared to NON-ALC advertisements, exposure to LTH + G advertisements increased (i) the proportion of respondents who correctly estimated harmful drinking levels, which in turn, strengthened intentions to drink less (42% of the total effect was mediated), and (ii) negative attitudes, which in turn, also increased intentions to drink less (35% mediated) and behavioural compliance (24% mediated). Compared to NON-ALC, LTH advertisements increased negative attitudes, which in turn strengthened intentions to drink less (53% mediated).

CONCLUSIONS

When paired with effective alcohol harm reduction television advertisements, messages promoting low-risk drinking guidelines can increase drinkers' intentions to reduce their alcohol consumption and compliance with low-risk drinking guidelines.

Impact of health warning labels communicating the risk of cancer on alcohol selection: an online experimental study

AIMS

Evidence from tobacco research suggests that health warning labels (HWLs) depicting the adverse consequences of consumption change smoking behaviours, with image-and-text (also known as 'pictorial' or 'graphic') HWLs most effective. There is an absence of evidence concerning the potential impact of HWLs placed on alcohol products on selection of those products. This study aimed to obtain a preliminary assessment of the possible impact of (i) image-and-text, (ii) text-only, and (iii) image-only HWLs on selection of alcoholic versus non-alcoholic drinks.

DESIGN

A between-subjects randomised experiment with a 2 (image: present versus absent) × 2 (text: present versus absent) factorial design.

SETTING

The study was conducted on the online survey platform Qualtrics.

PARTICIPANTS

Participants (n = 6024) were adults over the age of 18 who consumed beer or wine regularly (i.e. at least once a week), recruited through a market research agency.

INTERVENTIONS

Participants were randomised to one of four groups varying in the HWL displayed on the packaging of alcoholic drinks: (i) image-and-text HWL; (ii) text-only HWL; (iii) image-only HWL; and (iv) no HWL. HWLs depicted bowel cancer, breast cancer and liver cancer, which were each displayed twice across six alcoholic drinks. Each group viewed six alcoholic and six non-alcoholic drinks and selected one drink that they would like to consume.

MEASUREMENTS

The primary outcome was the proportion of participants selecting an alcoholic versus a non-alcoholic drink.

FINDINGS

Alcoholic drink selection was lower for all HWL types compared with no HWL (image-and-text: 56%; image-only: 49%; text-only: 61%; no HWL: 77%), with selection lowest for HWLs that included an image. Image-and-text HWLs reduced the odds of selecting an alcoholic drink compared with text-only HWLs (OR = 0.80, 95% CI = 0.69, 0.92), but increased the odds of selecting an alcoholic drink compared with image-only HWLs (OR = 1.34, 95% CI = 1.16, 1.55).

CONCLUSIONS

Health warning labels communicating the increased risk of cancers associated with alcohol consumption reduced selection of alcoholic versus non-alcoholic drinks in a hypothetical choice task in an online setting; labels displaying images had the largest effect. Their impact in laboratory and real-world field settings using physical products awaits investigation.

Implementing Health Warnings on Alcoholic Beverages: On the Leading Role of Countries of the Commonwealth of Independent States

Despite being a psychoactive substance and having a major impact on health, alcohol has to date escaped the required labeling regulations for either psychoactive substances or food. The vast majority of the countries in the WHO European Region have stricter labeling requirements for bottled water and health warning provisions for over-the-counter medications than for alcoholic beverages. However, more progress in implementing health warnings has been made in the eastern part of the WHO European Region, largely because of the recent technical regulation put in place by the newly formed Eurasian Economic Union. The present contribution provides an overview of the existing legislation regarding the placement of alcohol health warnings on advertisements and labels on alcohol containers in the countries of the Commonwealth of Independent States (CIS; Armenia, Azerbaijan, Belarus, Kazakhstan, Kyrgyzstan, Moldova, Russia, Tajikistan, Turkmenistan, and Uzbekistan) and discusses their potential gaps and shortfalls. It also reviews the evolution of the Eurasian Economic Union Technical Regulation 047/2018, which is, to date, the only international document to impose binding provisions on alcohol labeling. The technical regulation's developmental process demonstrates how the comprehensive messages and strong requirements for health warnings that were suggested initially were watered down during the consultation process.

Testing Alcohol Labels as a Tool to Communicate Cancer Risk to Drinkers: A Real-World Quasi-Experimental Study

Objective:

This study tested the initial and continued effects of cancer warning labels on drinkers’ recall and knowledge that alcohol can cause cancer.

Method:

A quasi-experiment was conducted to examine changes in the intervention versus comparison site for three outcomes: unprompted and prompted recall of the cancer warning, and knowledge that alcohol can cause cancer. The intervention site applied cancer warning labels to alcohol containers in its liquor store for 1 month, and the two liquor stores in the comparison site did not apply cancer labels. In total, 2,049 unique cohort participants (1,056 male) were recruited at liquor stores in the intervention and comparison sites to participate in surveys 4 months before labels were applied and 2 and 6 months after the cancer label was halted because of alcohol industry interference. Generalized estimating equations tested differences in outcomes between sites over time adjusting for socio-demographics and other covariates.

Results:

Two months after the cancer label, unprompted (+24.2% vs. +0.6%; adjusted odds ratio [AOR] = 32.7, 95% CI [5.4, 197.7]) and prompted (+35.7% vs. +4.1%; AOR = 6.2, 95% CI [3.6, 10.9]) recall increased to a greater extent in the intervention versus comparison site. There was a 10% greater increase in knowledge (+12.1% vs. +11.6%; AOR = 1.1, 95% CI [0.7, 1.5]) 2 months after the cancer label in the intervention versus comparison site. Similar results were found 6 months after the cancer label for all three outcomes.

Conclusions:

In a real-world setting, cancer warning labels get noticed and increase knowledge that alcohol can cause cancer. Additional cancer label intervention studies are required that are not compromised by industry interference.

News Media and the Influence of the Alcohol Industry: An Analysis of Media Coverage of Alcohol Warning Labels With a Cancer Message in Canada and Ireland

OBJECTIVE

Media coverage of alcohol-related policy measures can influence public debate and is often more aligned with interests of the alcohol industry than public health. The purpose of this study was to examine the framing of news coverage of alcohol warning label (AWL) initiatives that included a cancer message on alcohol containers in two different countries. Policy contexts and industry perspectives were also evaluated.

METHOD

We identified and systematically reviewed news articles published between 2017-2019 covering an AWL academic study in Yukon, Canada, and labeling provisions in a Public Health (Alcohol) Bill in Ireland. Both included a cancer message. News stories were coded for media type and topic slant; inclusion of alcohol industry perspectives was examined using content analysis.

RESULTS

Overall, 68.4% of media articles covering the Yukon Study (n = 38) and 18.9% covering the Ireland Bill (n = 37) were supportive of AWLs with a cancer message. The majority of articles in both sites presented alcohol industry perspectives (Yukon, 65.8%; Ireland, 86.5%), and industry arguments opposing AWLs were similar across both contexts. In articles with statements from industry representatives, the label message was frequently disputed by distorting or denying the evidence that alcohol causes cancer (n = 33/43).

CONCLUSIONS

News coverage of AWLs with a cancer message was more supportive in Canada than Ireland, where alcohol industry perspectives were consistently foregrounded. Industry arguments opposing the cancer label bore similarities across contexts, often distorting or denying the evidence. Increasing awareness of industry messaging strategies may generate more critical coverage of industry lobbying activities and increase public support for alcohol policies.

Baseline Assessment of Alcohol-Related Knowledge of and Support for Alcohol Warning Labels Among Alcohol Consumers in Northern Canada and Associations With Key Sociodemographic Characteristics

OBJECTIVE

Evidence-informed alcohol warning labels (AWLs) are a promising, well-targeted strategy to increase consumer awareness of health risks. We assessed consumers' baseline knowledge of alcohol-related cancer risk, standard drinks, and low-risk drinking guidelines as well as levels of support for AWLs. We further assessed associations with sociodemographic factors.

METHOD

Forming part of a larger study testing new evidence-informed AWLs in a northern Canadian territory compared with a neighboring territory, baseline surveys were completed among liquor store patrons systematically selected in both sites. Chi-square and multivariable logistic regression analyses were performed to assess outcomes.

RESULTS

In total, 836 liquor store patrons (47.8% female) completed baseline surveys across both sites. Overall, there was low knowledge of alcohol-related cancer risk (24.5%), limited ability to calculate a standard drink (29.5%), and low knowledge of daily (49.5%) and weekly (48.2%) low-risk drinking guideline limits. There was moderate support for AWLs with a health warning (55.9%) and standard drink information (51.4%), and lower support for low-risk drinking guideline labels (38.7%). No sociodemographic characteristics were associated with cancer knowledge. Identifying as female and having adequate health literacy were associated with support for all three AWLs; high alcohol use was associated with not supporting standard drink (adjusted odds ratio = 0.60, 95% CI [0.40, 0.88]) and low-risk drinking guideline (adjusted odds ratio = 0.57, 95% CI [0.38, 0.87]) labels.

CONCLUSIONS

Few consumers in this study had key alcohol-related health knowledge; however, there was moderate support for AWLs as a tool to raise awareness. Implementation of information-based interventions such as evidence-informed AWLs with health messages including alcohol-related cancer risk, standard drink information, and national drinking guidelines is warranted.

Use as directed: do standard drink labels on alcohol containers help consumers drink (ir)responsibly? Real-world evidence from a quasi-experimental study in Yukon, Canada

INTRODUCTION AND AIMS

This paper examines the impact of an alcohol labelling intervention on recall of and support for standard drink (SD) labels, estimating the number of SDs in alcohol containers, and intended and unintended use of SD labels.

DESIGN AND METHODS

A quasi-experimental study was conducted in Canada where labels with a cancer warning, national drinking guidelines and SD information were applied to alcohol containers in the single liquor store in the intervention site, while usual labelling continued in the two liquor stores in the comparison site. Three waves of surveys were conducted in both sites before and at two time-points after the intervention with 2049 cohort participants. Generalised estimating equations were applied to estimate changes in all outcomes.

RESULTS

Participants in the intervention relative to the comparison site had greater odds of recalling [adjusted odds ratio (AOR) 5.69, 95% confidence interval (CI) 3.02, 10.71] and supporting SD labels (AOR 1.49, 95% CI 1.04, 2.12) and lower odds of reporting using SD labels to purchase high strength, low-cost alcohol (AOR 0.65, 95% CI 0.45, 0.93). Exposure to the labels had negligible effects on accurately estimating the number of SDs (AOR 1.06, 95% CI 0.59, 1.93) and using SD labels to drink within guidelines (AOR 1.04, 95% CI 0.75, 1.46).

DISCUSSION AND CONCLUSIONS

Evidence-informed labels increased support for and decreased unintended use of SD labels. Such labels can improve accuracy in estimating the number of SDs in alcohol containers and adherence to drinking guidelines.

Alcohol Use and Cancers of the Gastrointestinal Tract. Epidemiology and Preventive Implications

Introduction: Alcohol is a carcinogen for human cancer. This contribution summarizes the relationships between alcohol use and gastrointestinal cancers, and implications for prevention. Methods: Comparative risk assessment and narrative literature review. Results: The following gastrointestinal cancer sites were found to be causally impacted by alcohol use: lip and oral cavity, pharynx other than nasopharynx, esophagus, colon and rectum, and liver. Globally, 368,000 deaths (304,000 men and 64,000 women) and more than 10 million disability-adjusted life years (DALYs) lost (10.1 million; 8.4 million men and 1.6 million women) in 2016 were attributable to alcohol use, making up about 10% of all deaths and DALYs lost due to these cancers, respectively. There are effective and cost-effective alcohol control policies available to reduce this burden, namely the best buys of increasing taxation, reducing availability, and banning advertisement. In addition, public knowledge about the alcohol-cancer link should be increased. Discussion: There are a number of assumptions underlying these estimates, but overall all of them seem to be conservative.

Examining the Impact of Alcohol Labels on Awareness and Knowledge of National Drinking Guidelines: A Real-World Study in Yukon, Canada

OBJECTIVE

Alcohol labels are one strategy for communicating health information to consumers. This study tested the extent to which consumers recalled alcohol labels with national drinking guidelines and examined the impact of labels on awareness and knowledge of the guidelines.

METHOD

A quasi-experimental study was conducted in two jurisdictions in northern Canada examining the impact of labels on the following outcomes: unprompted and prompted recall of the drinking guideline label message, awareness of the drinking guidelines, and knowledge of the daily and weekly recommended drink limits. The intervention site applied labels with national drinking guidelines, a cancer warning, and standard drink information to alcohol containers in its liquor store, whereas the comparison site did not apply these labels. In total, 2,049 cohort participants in both sites were recruited to complete surveys before and at two time points after the intervention. Changes in outcomes were examined using generalized estimating equations.

RESULTS

After the intervention, unprompted and prompted recall of the drinking guideline label message increased more in the intervention versus comparison site (adjusted odds ratio [AOR] = 10.8, 95% CI [0.9, 127.6]; AOR = 7.0, 95% CI [3.3, 14.9], respectively). Awareness of the drinking guidelines increased 2.9 times more in the intervention versus comparison site (AOR = 2.9, 95% CI [2.0, 4.3]). In addition, knowledge of the daily and weekly drink limits increased 1.5 and 1.4 times more in the intervention versus comparison site, respectively (daily: AOR = 1.5, 95% CI [1.0, 2.1]; weekly: AOR = 1.4, 95% CI [1.0, 2.0]).

CONCLUSIONS

Enhanced alcohol labels get noticed and may be an effective population-level strategy for increasing awareness and knowledge of national drinking guidelines.

Two months after the cancer label, unprompted (+24.2% vs. +0.6%; adjusted odds ratio [AOR] = 32.7, 95% CI [5.4, 197.7]) and prompted (+35.7% vs. +4.1%; AOR = 6.2, 95% CI [3.6, 10.9]) recall increased to a greater extent in the intervention versus comparison site. There was a 10% greater increase in knowledge (+12.1% vs. +11.6%; AOR = 1.1, 95% CI [0.7, 1.5]) 2 months after the cancer label in the intervention versus comparison site. Similar results were found 6 months after the cancer label for all three outcomes.

CONCLUSIONS

In a real-world setting, cancer warning labels get noticed and increase knowledge that alcohol can cause cancer. Additional cancer label intervention studies are required that are not compromised by industry interference.
