The Institute has an internationallyrecognised reputation for providing evidence-based research to inform policy and practice, particularly in regards to alcohol policy. NDRI therefore welcomes the review of food labelling laws and the opportunity to provide input into the potential introduction of alcohol warning and advisory labels (referred to as warning labels in this submission) as a new strategy to help reduce the harm caused by alcohol in Australia. In this submission, NDRI will focus only on warning labels and not the myriad other food labelling laws the review panel is considering. NDRI will endeavour to present the research evidence that outlines the effectiveness or otherwise of alcohol warning labels. NDRI acknowledges that, in 2009, key staff members involved in the preparation of this submission also produced two reports on the impact of alcohol warning labels for Food Standards Australia New Zealand. Background and Context More than 20 countries have adopted alcohol warning labels. Those labels vary, both in terms of their presentation – from image only to written warnings – and their focus – from alcohol use during pregnancy to drink driving. Despite this there is, unfortunately, a limited research base to inform our understanding of the effectiveness of warning labels. Most publications have come from the U.S. and are based on data from that country, and the current research base does not for example allow an accurate comparison between potential impacts of voluntary versus mandated alcohol warning labels. This submission, and indeed the considerations of the review panel, should be viewed within this context. However, that is not to say that there is no evidence regarding the effectiveness of warning labels, nor that there is evidence that they are ineffective or have no impact. Effectiveness of Warning Labels The research evidence that is available indicates that: Consumers are able to recall the presence of warning labels even though often most are not particularly noticeable and do not stand out from their background; A substantial proportion of alcohol consumers, including younger people, who have reported that they had seen an alcohol warning label could recall the message; Younger women and heavier drinkers may be more likely to notice warning labels; and Over time, and thus increased exposure, more people will become aware of the existence of warning labels. A small body of research indicates that warning labels have some impact on judgements about risks associated with alcohol consumption. In terms of translating that into the impact of warning labels on behaviour, some research indicates that the introduction of warning labels in the U.S. was associated with a self-reported increase in the likelihood of respondents discussing the risks of alcohol. There is also some limited evidence that warning labels prompted pregnant women to discuss alcohol consumption and the more types of warnings consumers are exposed to – on advertisements, point of sale promotions etc – the more likely they were to discuss alcohol-associated risks. These are important findings. Information included in warning labels appears to have resulted in consumers being more informed about risks. In considering the effectiveness of warning labels, it may be instructive to consider some theoretical perspectives in understanding the influence of health communications, including warning labels. General health information research indicates that providing information about the risks of a particular behaviour may not result in behaviour change. These health communication models predict that a warning label, or other media, communicating messages about health risks may be noticed and understood in general but might not be interpreted by an individual as having personal relevance. For example, selfserving optimism may increase the sense that the risks are only pertinent for others. Health information in a warning label may then be recognised by an individual but other strategies, such as interpersonal discussion about risk and the individual having access to strategies to help them change their behaviour, will be required. This suggests that while warning labels may be worthwhile as a means to inform people about risk, on their own they will probably not be sufficient to ensure behaviour change – other strategies will also be required. What other Strategies have Impact – the Evidence The body of evidence about effective alcohol interventions has been summarised by various groups (e.g. Babor et al 2003; Loxley et al 2004, Chikritzhs 2007). Effective interventions include: controls on availability through price mechanisms (e.g. Waagenar et al 2009); controls on physical access through hours of sale, number of outlets, and age restrictions; enforcement of liquor licence laws; ensuring low risk drinking contexts; interventions aimed at specific risks (e.g. random breath testing); and brief and more intensive treatment options. More recently, attention has focussed on the potential of sustained and well-resourced social marketing initiatives in combination with the above measures and changes to alcohol promotion efforts adopted by the alcohol industry. Strategies to more effectively communicate health messages, for example via warning labels, should be considered in the broader context of, and in combination with, other effective interventions This suggests that if warning labels are adopted, they should be consistent with, and where possible linked to, other alcohol policy and related strategies. For example, warning labels conveying messages about the risks of drinking for women of childbearing age and drinking while pregnant would be complemented by other strategies and activities, such as controls on alcohol availability, advice by primary health care staff and increased screening of alcohol use before and during pregnancy. Lessons from other Domains – Tobacco While, as indicated, the evidence surrounding the effectiveness of alcohol warning labels is limited, there is a stronger evidence base regarding the impact of tobacco warning labels. Acknowledging distinctions between tobacco and alcohol, tobacco still provides important lessons for alcohol interventions. Evidence from Australia and overseas indicates that to have impact, tobacco warning labels need to be prominent, graphic and incorporate images as well as text. Evidence from the tobacco arena also indicates that messages are most effective when they are mandatory and when messages and images are frequently changed and alternated. The content, style and presentation of tobacco warnings can markedly affect how noticeable and memorable they are, and influence their impact. It is important to note that tobacco warning labels have constituted one component of an overall, complementary, tobacco strategy. Summary and discussion The need for a multi-faceted approach Approaches to responding to alcohol problems are likely to be most effective when multi-faceted and evidence-based. Strategies such as social marketing campaigns, school drug education, brief interventions and, in all likelihood, warning labels should be accompanied by other approaches that address the influence of factors such as alcohol availability, enforcement of drinking laws, alcohol promotion, family dynamics and resources and parenting skills on people’s drinking behaviour. The need to build the evidence base As indicated, the research base is limited, mostly from the U.S. and observed effects have largely been on information recall. There is little to suggest any impact on behaviour and much of the research has been short-term – six months or less. Such a brief period of time may not be sufficient for individuals to act on the information contained in warning labels. Furthermore, label content has focussed primarily on a narrow band of messages, such as pregnancy/birth defects, drinking and driving, operating machinery and information about alcohol content/standard drinks. Much of the research has been on warning labels that, compared to tobacco warning labels, have not been particularly graphic, have not used prominent visual images and text, and have not been rotated. Rather than claiming that they have no impact (which is contrary to the evidence on their impact on message recall) we might perhaps be surprised that, in their current form, they have had any impact at all. However, it is important that any step to embrace alcohol warning labels include quality evaluation to ensure they are consistent with and complement other strategies and to assess their individual and combined impact on knowledge of risks and behaviour. Conclusion The National Drug Research Institute believes there is merit in considering the introduction of alcohol warning labels in Australia. However, as the tobacco arena indicates, effective alcohol warning labels are most likely to be those which are prominent, graphic and incorporate images as well as text. Any introduction of alcohol warning labels should also be coupled with adequate investment in properly evaluating their impact. This will include identifying their benefits in the contexts of any costs for the community, governments and industry. The key consideration is that warning labels should be considered as one aspect of a comprehensive strategy to minimise the harm caused by alcohol in Australia. While it may be challenging in some cases to attribute changes in behaviour solely to alcohol warning labels, we concur with other reviewers, such as Wilkinson and Room (2008a; 2008b) and Anderson (DHS, 2008), who have concluded that warning labels are warranted as part of a multi-faceted comprehensive strategy: “…adding warning labels to alcohol containers has a longer term social utility in helping to establish social understanding that alcohol is a special and hazardous commodity.” (Wilkinson and Room 2008a, p.19).
