‘Everything causes cancer’: how Australians respond to the message that alcohol causes cancer

How much do Europeans know about the link between alcohol use and cancer? Results from an online survey in 14 countries

OBJECTIVE

In the EU, which has the highest drinking levels worldwide, cancer is the primary cause of alcohol-attributable deaths. Existing studies show gaps in public knowledge, but there is lack of systematic appraisal. The report presents original data from a cross-sectional survey conducted within the framework of an online experimental study in 14 European countries, which among other things assessed baseline knowledge of the alcohol-NCD link, particularly cancer.

METHODS

Online questionnaire among adults who consume alcohol conducted in 14 countries in 2022-2023 using different recruitment strategies and applying population weights for the final sample. Baseline assessments measured participants' knowledge of alcohol-attributable health issues (with a specific focus on cancer).

RESULTS

Baseline knowledge assessment showed that 90% indicated a causal role of alcohol for liver disease, 68% for heart diseases, and only 53% for cancer. Knowledge of specific alcohol-attributable cancer types was lower, with 39% aware of the link between alcohol use and colon cancer, 28% regarding oral cancer, and only 15% regarding female breast cancer. Knowledge levels varied across different countries and population groups.

CONCLUSION

Most Europeans do not know which cancers can be caused by alcohol use and knowledge is low specifically for female breast cancer. More awareness raising and prevention efforts are needed, such as the placement of cancer-specific health warnings on alcohol container labels.

Revisiting Candidacy: What Might It Offer Cancer Prevention?

The notion of candidacy emerged three decades ago through Davison and colleagues’ exploration of people’s understanding of the causes of coronary heart disease. Candidacy was a mechanism to estimate one’s own or others risk of disease informed by their lay epidemiology. It could predict who would develop illness or explain why someone succumbed to it. Candidacy’s predictive ability, however, was fallible, and it was from this perspective that the public’s reticence to adhere to prevention messages could be explained, as ultimately anybody could be ‘at-risk’. This work continues to resonate in health research, with over 700 citations of Davison’s Candidacy paper. Less explored however, is the candidacy framework in its entirety in other illness spheres, where prevention efforts could potentially impact health outcomes. This paper revisits the candidacy framework to reconsider it use within prevention. In doing so, candidacy within coronary heart disease, suicide prevention, diabetes, and cancer will be examined, and key components of candidacy and how people negotiate their candidacy within differing disease contexts will be uncovered. The applicability of candidacy to address modifiable breast cancer risk factors or cancer prevention more broadly will be considered, as will the implications for public health policy.

How Are the Links between Alcohol Consumption and Breast Cancer Portrayed in Australian Newspapers?: A Paired Thematic and Framing Media Analysis

A dose-dependent relationship between alcohol consumption and increased breast cancer risk is well established, even at low levels of consumption. Australian women in midlife (45–64 years) are at highest lifetime risk for developing breast cancer but demonstrate low awareness of this link. We explore women’s exposure to messages about alcohol and breast cancer in Australian print media in the period 2002–2018. Methods: Paired thematic and framing analyses were undertaken of Australian print media from three time-defined subsamples: 2002–2004, 2009–2011, and 2016–2018. Results: Five key themes arose from the thematic framing analysis: Ascribing Blame, Individual Responsibility, Cultural Entrenchment, False Equilibrium, and Recognition of Population Impact. The framing analysis showed that the alcohol–breast cancer link was predominantly framed as a behavioural concern, neglecting medical and societal frames. Discussion: We explore the representations of the alcohol and breast cancer risk relationship. We found their portrayal to be conflicting and unbalanced at times and tended to emphasise individual choice and responsibility in modifying health behaviours. We argue that key stakeholders including government, public health, and media should accept shared responsibility for increasing awareness of the alcohol–breast cancer link and invite media advocates to assist with brokering correct public health information.

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.

"Women of my age tend to drink": the social construction of alcohol use by Australian and Danish women aged 50-70 years

In Australia and Denmark, women aged 50-70 years are more likely than younger women to consume alcohol at levels that exceed national low risk drinking guidelines. To explore and possibly help explain this sociocultural shift in patterns of alcohol use, this research investigated the social construction of alcohol use amongst 49 women (25 in Northern Denmark, 24 in Western Australia) aged 50-69 years. The women viewed drinking as normal and acceptable. While some women reported reducing their drinking due to health concerns, others neutralised alcohol-related health risks through compensatory behaviours including exercise. Such constructions arguably serve to sustain at-risk drinking amongst some women. Our research highlights that interventions to minimise alcohol-related health risks amongst middle-aged and young-old women should acknowledge that women's social construction of their drinking practices may prioritise subjective experiences of "being in control" while drinking, over biomedical understandings of the health impacts of alcohol.
