A randomized controlled trial of the effectiveness of combinations of 'why to reduce' and 'how to reduce' alcohol harm-reduction communications

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.

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.

Trends in and factors associated with parental provision of alcohol to minors in Western Australia, 2013-2019

INTRODUCTION

Some parents provide alcohol to their underage children, despite a range of negative outcomes being associated with this practice. The present study aimed to assess factors associated with and changes in parental provision behaviours from 2013 to 2019 in Western Australia.

METHODS

Annual cross-sectional online surveys were conducted (total n = 2635). Assessed variables included parents' demographic characteristics, alcohol use, awareness of the relevant Australian alcohol guideline, attitudes to parental provision of alcohol and provision behaviours. A binary logistic generalised linear model was used to identify factors associated with parental provision of alcohol.

RESULTS

Parental provision of alcohol prevalence decreased from 40% in 2013 to 27% in 2019. The following variables were significantly associated with parental provision: permissive attitudes to provision (β = 2.82); older parental age (β = 1.28); a lack of knowledge of the relevant guideline (β = 0.78); survey year (β = 0.083); and greater alcohol use (β = 1.12). Socioeconomic position was not associated with parental provision. Female parents were more likely to report that an adult in the household provided children with alcohol (β = 1.3) DISCUSSION AND CONCLUSIONS: The findings suggest that (i) although still commonplace, parental provision of alcohol to minors in Western Australia has declined over time; and (ii) the effectiveness of campaigns aiming to reduce this behaviour may be enhanced by targeting households with parents who are older and heavier drinkers and by including content that challenges permissive views on alcohol provision to minors.

Effectiveness of a French mass-media campaign in raising knowledge of both long-term alcohol-related harms and low-risk drinking guidelines, and in lowering alcohol consumption

AIMS

To evaluate the effectiveness of a French mass-media campaign in raising knowledge of both long-term alcohol-related harms (LTH) and low-risk drinking guidelines (LRDG), as well as in lowering alcohol consumption.

DESIGN

An 8-month longitudinal survey from February to October 2019, with three waves of on-line data collection (T0 before the campaign, T1 just after it ended and T2 6 months after it ended).

SETTING

France.

PARTICIPANTS

A total of 2538 adult drinkers (aged 18-75 years).

MEASUREMENTS

The main outcomes' variables were LTH knowledge (cancer, hypertension, brain haemorrhage), LRDG knowledge (two guidelines: 'maximum of two drinks a day' and 'minimum of 2 days without alcohol per week'), intention to reduce alcohol consumption and self-declared consumption with respect to the French LRDG. At T1, exposure to the campaign was measured using self-reported campaign recall.

FINDINGS

In T1, we observed significant positive interactions between exposure group based on campaign recall and survey waves on knowledge of (i) the 'maximum two drinks a day' guideline [adjusted odds ratio (aOR) = 1.32, 95% confidence interval (CI) = 1.08-1.62, P = 0.008], (ii) brain haemorrhage (aOR = 1.80, 95% CI = 1.44-2.25, P < 0.001) and (iii) hypertension (aOR = 1.41, 95% CI = 1.09-1.81, P = 0.008) risks. Campaign exposure was also associated with a significant decrease in at-risk drinking in women (aOR = 0.67, 95% CI = 0.50-0.88, P = 0.004). No significant interaction was observed at T1 for the knowledge of the 'minimum of 2 days without alcohol a week' guideline, or of cancer risk. At T2, no significant interaction was observed for the main outcomes' variables.

CONCLUSIONS

There appears to be an association between exposure to a 2019 French mass-media campaign to raise knowledge of long-term alcohol-related harms and low-risk drinking guidelines and reduce alcohol consumption and (i) improved knowledge of the 'maximum two drinks per day guideline', (ii) knowledge of the risks of hypertension and brain haemorrhage and (iii) a reduction in the proportion of people exceeding low-risk drinking guidelines (in the general population only). These associations were only observed over the short term and, in some cases, only for certain segments of the population.

Gamblers' perceptions of responsibility for gambling harm: a critical qualitative inquiry

Background

Gambling has traditionally been conceptualised as an issue of addiction and personal responsibility. While there are now clear public health models that recognise that gambling harm is caused by a range of socio-cultural, environmental, commercial and political determinants, government and industry messages about gambling are still largely personal responsibility focused. Given the well-recognised issues associated with personal responsibility paradigms, this study sought to understand how gamblers themselves conceptualised responsibility for gambling harm.

Methods

A qualitatively led online panel survey was conducted with 363 adult gamblers in New South Wales and Victoria, Australia. Participants were asked to respond to what they thought were the causes of gambling harm, and what could be done to prevent harm. A reflexive thematic analysis was conducted.

Results

Six common tropes were constructed from gamblers’ responses: (1) Gambling in moderation; (2) Personal responsibility for rational behaviour; (3) Character flaws; (4) Personal responsibility to seek help; (5) More education is needed; and (6) Governments are responsible for action – but motivation and efficacy are questioned. Gamblers primarily understood gambling harm as being a matter of personal responsibility, and government responsibility was generally seen as limited to providing information to facilitate informed gambling choices.

Conclusions

This study demonstrates that gamblers’ perceptions of gambling harm are similar to the personal responsibility framings and tropes present in industry and government messaging strategies. Refocusing public communication strategies away from ‘responsible gambling’ messaging, and towards evidence-based approaches, will be an important part of addressing the harms associated with gambling.

Understanding and Overcoming Barriers to Drink Counting

Objectives: Drink counting has been found to be an effective protective behavioral strategy (PBS) to reduce alcohol consumption. However, little is known about attitudes to this strategy and barriers and facilitators to its use. The aim of this study was to explicate these factors and draw comparisons with less efficacious PBSs. Method: In Stage 1, 1,703 Australian drinkers were surveyed about their perceptions of five PBSs ("Count the number of drinks you have," "Drink slowly rather than gulping or sculling," "Refuse an alcoholic drink you are offered because you don't really want it," "Avoid trying to 'keep up' or 'outdrink' others," and "Decide not to exceed a certain number of drinks"). Respondents reported perceived believability, relevance, ease of use, effectiveness, barriers, and facilitators. In Stage 2, 10 focus groups were conducted with drinkers to identify potential methods of effectively promoting drink counting. Results: Overall, drink counting was rated less favorably than the less-efficacious PBSs, indicating a need to inform drinkers of the importance and feasibility of this strategy to encourage its use. The main identified barriers were a lack of awareness of the long-term harms associated with alcohol use, social factors (e.g., peer pressure), and difficulty counting when intoxicated. Participants suggested improving drinkers' understanding of alcohol-related harms and developing mechanisms to assist with counting. Conclusion: To encourage drink counting, information campaigns are needed to educate the community about the long-term risks of alcohol use. Evidenced-based mechanisms to facilitate drink counting may be welcomed by drinkers.
