Evaluation of the population-level impacts of the LiveLighter® obesity prevention campaign from 2012 to 2019 based on serial cross-sectional surveys.

BACKGROUND: Halting and reversing the upward trend in obesity requires sustained implementation of comprehensive, evidence-based strategies at the population-level. The LiveLighter® program targets adults using a range of public education strategies, including mass media campaigns, to support healthy lifestyle changes to attain or maintain a healthy weight and reduce the risk of chronic disease. LiveLighter® has been implemented in Western Australia (WA) since 2012 and, to our knowledge, includes the longest running adult-targeted mass media campaign for healthy weight and lifestyle promotion and education globally. This evaluation assessed the impact of LiveLighter® on WA adults' knowledge, intentions and behaviours as they relate to healthy eating and body weight from 2012 to 2019. METHODS: LiveLighter® mass media campaigns, which are TV-led and aired statewide, depict genuine, graphic imagery of visceral fat around internal organs to raise awareness about the link between excess body weight and chronic diseases; demonstrate how unhealthy food and drink consumption can contribute to unhealthy weight gain; and recommend healthy alternatives. Cross-sectional telephone surveys were conducted at baseline and following each campaign phase with an independent, randomly selected sample of WA adults aged 25 to 49 years (n = 501 to n = 1504 per survey) to assess their knowledge of the link between excess body weight and chronic diseases, and their intentions and behaviours related to healthy eating and weight. Multivariable logistic regression models were undertaken to assess differences in responses between baseline and each post-campaign survey. RESULTS: Compared to baseline, there were significant increases in the proportion of respondents reporting knowledge of excess body weight as a risk factor for certain cancers and type 2 diabetes, intentions to eat more fruit and vegetables and drink less sugar sweetened beverages (SSBs) in the next seven days, and the proportion of respondents who reported meeting guidelines for daily vegetable intake. Reported consumption of SSBs significantly decreased. CONCLUSIONS: LiveLighter® is associated with improvements in knowledge of the health risks associated with excess body mass, increased vegetable intake and reduced SSB consumption in WA adults. These findings support the use of sustained, well-designed healthy lifestyle promotion and education programs as part of a comprehensive obesity prevention strategy.

Can counter-advertising dilute marketing effects of alcohol sponsorship of elite sport: A field experiment.

AIMS: To test whether showing spectators counter-advertisements exposing alcohol harms alone, or exposing alcohol harms and alcohol sponsorship, before watching an alcohol-sponsored sporting event promotes less favourable post-event attitudes and intentions towards alcohol sponsor brands and alcohol in general. DESIGN: On-line between-subjects experiment. SETTING: Australia. PARTICIPANTS: A sample of Australian adults aged 18-49 years who planned to watch an alcohol-sponsored National Rugby League (NRL) State of Origin series game was recruited through an online panel. INTERVENTIONS: Participants were randomly assigned to one of three counter-advertising conditions: control (neutral advertisement); counter-advertisement exposing alcohol harms; and counter-advertisement exposing alcohol sponsorship and harms, to view at least four times during the week before watching the alcohol-sponsored sporting event. MEASUREMENTS: Participants (n = 1932) completed a pre-test questionnaire a week before the sporting event. Within 4 days of watching the sporting event, participants completed post-test measures assessing sponsor brand awareness, attitudes and preferences towards the brand, as well as knowledge, attitudes and intentions for alcohol in general (n = 1075). FINDINGS: Compared with the control advertisement, the counter-advertisement exposing alcohol sponsorship and harms promoted higher (6-13%) awareness of sponsor brands, less favourable attitudes towards sponsor brands and drinking beer, lower purchase intentions for sponsor brands (Cohen's d = 0.15, 0.31, 0.27, respectively) and perceived less image-based similarity and fit between the sporting event and sponsor brands (Cohen's d = 0.20 and 0.56). Both counter-advertisements promoted lower perceptions of the appropriateness of consuming alcohol while watching sport (Cohen's d = 0.22 and 0.34), higher awareness of alcohol harms (6-34%) and higher intentions (8-13%) to reduce alcohol consumption than the control advertisement. CONCLUSIONS: At alcohol-sponsored sporting events, counter-advertisements addressing alcohol harms may promote knowledge of harms and intentions to drink less. Counter-advertisements that additionally expose and critique alcohol sponsorship may detract from perceptions of sponsor brand image and intentions to purchase the sponsor's products.

Can counter-advertising exposing alcohol sponsorship and harms influence sport spectators' support for alcohol policies? An experimental study.

BACKGROUND: Exposure to alcohol advertising and sponsorship through elite sport is associated with harmful use of alcohol. Owing to strong financial and cultural ties between alcohol and sport in Australia, policy action to restrict alcohol sport sponsorship is unlikely to occur without strong public support for change. This study tested whether exposure to counter-advertising exposing industry marketing of harmful products-a technique shown to be effective in tobacco control-promotes higher support for policy change and less favourable beliefs about the alcohol industry among sport spectators. METHODS: A sample of 1,075 Australian adults aged 18-49 years who planned to watch an National Rugby League (NRL) State of Origin series game, featuring prominent alcohol sponsorship, was recruited through an online panel and randomly assigned to one of three conditions: control (neutral advertisement); counter-advertisement exposing alcohol harms; counter-advertisement exposing alcohol sponsorship and harms. Participants completed a pre-test questionnaire and viewed their assigned counter-advertisement multiple times in the 5-7 days before the NRL game. Within four days of watching the game, participants completed post-test measures. RESULTS: Compared to both the control advertisement and the counter-advertisement exposing alcohol harms, participants who viewed the counter-advertisement exposing alcohol sponsorship and harms were significantly more likely to indicate support for each of four policies aimed at restricting sports-related alcohol marketing, including the complete removal of alcohol sponsorship from sport (51% vs. 32% and 37%). They were also significantly less likely to agree with statements such as "alcohol companies should be allowed to sponsor sport since their products are legal" (39% vs. 63% and 60%) and significantly less likely to report liking alcohol companies in general (38% vs. 59% and 54%). There were no significant differences in policy support or industry beliefs between participants who saw the counter-advertisement exposing alcohol harms and those who saw the control advertisement. CONCLUSION: Counter-advertising employing messages that expose and critique the intent and impact of pervasive alcohol sponsorship in sport has potential to bolster public support for policies targeting alcohol sport sponsorship, diminish beliefs supportive of alcohol industry marketing strategies and enhance negative views of alcohol companies and their marketing practices.

Food purchasing practices in various retail settings and dietary intake: A cross-sectional survey of Australian adolescents.

BACKGROUND/AIMS: Discretionary, energy-dense, nutrient-poor food and drinks are heavily marketed and readily available in retail settings frequented by adolescents. This study examines associations between food purchasing practices in various retail settings and dietary intake among Australian adolescents. METHODS: Participants were students in years 8 to 11 (ages 12-17 years) who completed the 2009-10 (n = 13 790), 2012-13 (n = 10 309) or 2018 (n = 9102) National Secondary Students' Diet and Activity (NaSSDA) cross-sectional survey. Multistage stratified random sampling was used. An online survey completed at school assessed self-reported frequency of food purchasing practices in various retail settings and consumption of discretionary food, sugary drinks, fruit and vegetables. Generalised linear regression models examined associations between food purchasing practices and dietary behaviour. RESULTS: Relative to students who brought lunch from home, those who purchased lunch from school or nearby outlets reported higher intake of discretionary food and sugary drinks and lower fruit intake. Buying lunch from school was also associated with lower vegetable intake. Buying food or drinks on the school commute, outside school grounds during school hours, from supermarket checkouts, and using mobile phone apps were each associated with higher discretionary food and sugary drink intake (all P < .01). CONCLUSIONS: Purchasing food or drink in various retail settings is associated with higher intake of discretionary food and drink among Australian adolescents, and some purchasing practices appeared to displace fruit and vegetable intake. SO WHAT?: These findings highlight a need to improve the accessibility and promotion of healthier food and drink options in schools and other retail settings.

The health halo effect of 'low sugar' and related claims on alcoholic drinks: an online experiment with young women.

AIMS: To investigate whether 'low sugar' and related claims influence consumers' perceptions of the healthiness or other attributes of alcoholic drinks, promote greater consumption or impact diet and activity behaviour intentions. METHOD: N = 501 Australian women aged 18-35 viewed and rated six images of alcoholic drinks in a randomized online experiment with a 2 (claim: low sugar claim, no claim control) × 2 (drink type: cider, ready-to-drink spirits) between-subjects design. RESULTS: Participants who viewed drinks with low sugar claims rated them as healthier, less harmful to health, lower in sugar and kilojoules, and more suitable for weight management and a healthy diet than participants who viewed identical drinks with no claim (P < 0.001-P = 0.002). Drinks with low sugar claims were also perceived as being lower in alcohol (P < 0.001) despite being of equivalent alcohol content. There were no significant differences in anticipated social approval associated with consumption or in hypothetical intended consumption of the drinks, but participants who viewed drinks with low sugar claims were less likely to indicate they would compensate for consumption of the drink by modifying food intake or physical activity (P = 0.01). CONCLUSIONS: Low sugar and related claims on alcoholic drinks can generate a health halo: consumers generalise from a specific favourable attribute (low sugar) to misperceive other favourable health- and nutrition-related attributes, including lower alcohol content. Findings support calls to reconsider the permissibility of low sugar claims on alcoholic drinks as they may mislead consumers.

Exploring Intended and Unintended Reactions to Healthy Weight and Lifestyle Advertisements: An Online Experiment.

BACKGROUND: To address concerns that healthy weight and lifestyle campaigns (HWLCs) could have unintended psychological or behavioral consequences, this study tested reactions to TV advertisements from two HWLCs: LiveLighter® (employs graphic health effects messaging) and Swap It Don't Stop It (employs animation and light-hearted messaging). METHODS: An online between-subjects experiment tested reactions to one of five advertisements: "Toxic Fat"; "Sugary Drinks" (both from LiveLighter); "Become a Swapper"; "How to Swap It" (both from Swap It); and "HSBC Bank" (control) among 2,208 adults from Western Australia and Victoria, Australia. Responses assessed were cognitive and emotional reactions, behavioral intentions, internalized weight bias, antifat attitudes, self-esteem and body dissatisfaction. RESULTS: The HWLC advertisements prompted favorable cognitive reactions and weak to neutral positive and negative emotional responses. HWLC advertisements promoted stronger intentions to engage in adaptive lifestyle behaviors compared with the control advertisement. Intention to engage in maladaptive behaviors (e.g., skipping meals) was low overall and did not differ by condition. Compared with the control condition, participants who saw LiveLighter "Sugary Drinks" showed weaker disagreement with antifat attitudes; however, mean antifat attitude scores were still at the low end of the scale. HWLC advertisements did not promote internalized weight bias, reduced self-esteem or body dissatisfaction compared with the control advertisement. CONCLUSIONS: Overall, HWLC advertisements performed favorably compared with the control advertisement and showed no clear evidence of adverse impacts. Findings suggest HWLC advertisements may not promote negative psychological and behavioral consequences and can continue to be used in obesity prevention efforts.

Exploring classroom-based assessment for young EFL learners in the Chinese context: Teachers' beliefs and practices.

Classroom-based assessment (CBA) is an approach for learning improvement that has been advocated as having strong potential in enhancing learner autonomy of young language learners (YLLs). This study investigated Chinese primary school English as a foreign language (EFL) teachers' beliefs about CBA, their assessment practices, and the relationship between their CBA beliefs and practices. Drawing on data from a survey of 195 Chinese primary school EFL teachers, results showed that the teachers positively believed in the value of various CBA processes, including planning assessment, collecting learning evidence, making professional judgments and providing appropriate feedback, and they also attempted to enact these assessment practices; belief-practice alignment was also identified, showing that teachers' beliefs about CBA were significant predictors of their assessment practices. Implications are provided for promoting the implementation of CBA for YLLs in similar contexts.

Obesity prevention and related public health advertising versus competing commercial advertising expenditure in Australia.

Mass media campaigns can change attitudes and behaviours to improve population health. However, a key challenge is achieving share of voice in a complex and cluttered media environment. The aim of this study was to compare advertising expenditure on public health campaigns for obesity prevention (and related healthy eating and physical activity campaigns) with competing commercial categories of (a) sugary drinks, (b) artificially sweetened drinks and (c) diet/weight loss products and programmes. These commercial products may either undermine or dilute public health messages by directly contributing to poor health or confusing the public about the best ways to sustain a healthy lifestyle. Monthly estimates of advertising expenditure in Australian media (television, outdoor, cinema, radio, newspapers, magazines and digital) were obtained from Nielsen Media for 2016-18. Eligible public health advertising expenditure for the entire period (total AUD$27M) was vastly outweighed by the commercial categories of sugary drinks (AUD$129M) and diet/weight loss products and services (AUD$122M). Artificially sweetened drinks accounted for an additional AUD$23M of expenditure. These results highlight the need to rebalance the ratio of advertising to support public health in Australia through increased funding for obesity prevention and related campaigns, and critically, through government regulation to limit competing commercial advertising.

Trends and determinants of active school travel among Australian secondary school students: national cross-sectional data from 2009 to 2018.

OBJECTIVE: To examine active school travel trends and predictors among Australian secondary school students (aged 12-17) between 2009 and 2018. METHODS: Three cross-sectional surveys (2009-10: N=13,790; 2012-13: N=10,309; and 2018: N=9,102) using a web-based self-report questionnaire. Logistic regression was used to identify differences in active travel (to and/or from school every weekday) between survey years and predictors. RESULTS: From 2009-10 to 2012-13 to 2018, active travel decreased from 33.6% to 32.3% to 29.5% among females, and from 37.4% to 36.6% to 32.6% among males. Distance, female sex and regional location were associated with a lower likelihood of active travel. Students with pocket money, those who spoke a language other than English at home, and Aboriginal and/or Torres Strait Islander students were more likely to actively travel. CONCLUSIONS: Between 2009-10 and 2018, active school travel among secondary students in Australia declined. Several factors were found to be associated with active travel. IMPLICATIONS FOR PUBLIC HEALTH: This is the first national study on active travel trends among secondary students in Australia. The recent decline requires action given the increasing prevalence of overweight and climate change.

Health-Oriented Marketing on Alcoholic Drinks: An Online Audit and Comparison of Nutrition Content of Australian Products.

OBJECTIVE: Marketing, label design, and product innovation strategies are being used by the alcohol industry to position some products as "healthier choices." The aim of this study was to systematically document the content and prevalence of health-oriented marketing on alcohol products on the Australian market and to compare the online availability of nutrition information and the alcohol and nutrient content between products with and without such features. METHOD: Health-oriented marketing features on all beer, cider, and ready-to-drink (RTD) premixed drinks, and selected wines on the website of the largest liquor retailer in Australia were audited using a systematic coding protocol. Nutrition information was sought from manufacturer/brand websites. RESULTS: A total of 54% of beers, ciders, and RTDs featured health-oriented marketing, the most common forms being natural imagery or descriptors, or references to fruit ingredients. Twenty-one percent of audited wines featured health-oriented marketing. The prevalence of specific features varied by product category. Online availability of nutrition information for alcohol products was poor (12% of beer, cider, and RTDs). Products with health-oriented marketing were lower in energy and alcohol content than those without but were still classed as full-strength alcohol on average. CONCLUSIONS: Health-oriented marketing is prevalent on alcohol products sold in Australia. In the absence of universal and standardized health warning and energy content information on labels, permitted health-oriented marketing has the potential to mislead consumers about product healthiness or to detract from the perceived harm associated with alcohol consumption. Research to test this proposition is now needed to guide labeling policy reform.

LiveLighter® 'Junk Food' mass media campaign increases behavioural strategies to reduce consumption.

The LiveLighter® 2016 'Junk Food' campaign ran for 5 weeks in Western Australia (WA) and urged adults to reduce their junk food consumption to avoid weight gain and associated chronic disease. A cohort design assessed campaign impact on knowledge, beliefs and behaviour. Pre-campaign (n = 1501) and post-campaign (n = 737) telephone surveys of WA adults aged 25-49 were undertaken. A post-campaign-only sample (n = 501) controlled for pre-test effects. The campaign reached 57% of respondents and increased knowledge of the link between overweight and non-alcoholic fatty liver disease (78% cf. 87%; P < 0.01). Following campaign activity, respondents were more likely to avoid purchasing food from settings depicted in the advertisements (fast food outlets: 63% cf. 77%; service stations: 82% cf. 93%; vending machines: 87% cf. 96%; all P < 0.001), particularly among pre-campaign consumers of fast food and salty snacks (≤2 times/week). Weight-loss self-efficacy increased among adults with higher body weight and campaign exposure (89% cf. 97%; P < 0.01), and there was no increased endorsement of overweight stereotypes among the full sample. Support for fiscal disincentives and nutritional disclosure policies increased among healthy weight adults. LiveLighter® positively influenced knowledge, beliefs and behaviours, along with attitudes towards policies to encourage healthy eating, supporting LiveLighter® as an advocacy campaign.

Emotional Labor in Teaching Chinese as an Additional Language in a Family-Based Context in New Zealand: A Chinese Teacher's Case.

New Zealand is a multilingual and multicultural society, where English, Maori, and the New Zealand sign language are designated as its official languages. However, some heritage languages (e.g., Chinese/Mandarin Chinese, French, German, Japanese, and Korean, among others) are also taught either within or outside the national education system. During the past decade, an increasing number of students have chosen Mandarin Chinese (hereafter "Chinese") as an additional language (CAL) because of its fast-growing importance. To date, studies regarding CAL are mainly based on the mainstream Chinese programs (i.e., in schools or universities) or online platforms, with less attention paid to other types of teaching contexts (e.g., family-based and private tutoring contexts) where there also exist many potential challenges awaiting teachers. To fill in this gap, this study, based on a teaching program consisting of two families in New Zealand, explored the trajectories of a CAL teacher's emotional labor for 47 weeks to understand how she managed her emotions when she taught the language as well as balanced the relationship among the three parties: the institution, the two families, and herself. Narrative inquiry was used as a methodological approach. The data involved written and spoken narratives. Using inductive and deductive thematic analysis, findings revealed her different understandings of the emotional labor in the two families, respectively, during the program. Further analysis of the data revealed some factors that impacted her emotional labor and how they impacted her teaching in a family-based context. We concluded our study with a discussion of the implications of these findings for teaching CAL in similar contexts.

Prevalence and Correlates of Observed Sun Protection Behaviors Across Different Public Outdoor Settings in Melbourne, Australia.

Skin cancer prevention efforts in Australia have increasingly incorporated a focus on protection during incidental sun exposure. This complements the long-present messages promoting protection in high-risk settings and avoidance of acute intense bouts of sun exposure. Data from two waves of a cross-sectional direct observational survey was used to assess the prevalence and correlates of N = 12,083 adolescents' and adults' sun protection behavior (arm and leg cover, hat, sunglasses, and shade cover). Individuals were observed in public outdoor settings in Melbourne, Australia during peak ultraviolet (UV) times (11 a.m.-3 p.m.) on summer weekends. Settings included pools and beaches, parks and gardens, and for the first time in 2018, outdoor streets and cafés which may capture more incidental forms of sun exposure and represent another public setting where Australians commonly spend time outdoors. Females and older adults were consistently better protected than males and adolescents. Physical activity was strongly associated with low shade cover across settings. Weather was more strongly associated with sun protection at outdoor streets/cafes and parks/gardens than at pools/beaches but use of observed sun protection (particularly arm cover and covering hat) was low across settings. Continued public education about UV risk and its relation to weather and the seasons is needed to promote the routine use of multiple forms of sun protection during outdoor activities in peak UV times, especially among males and adolescents. Findings also highlight the importance of considering activity demands of public spaces in shade planning to optimize sun protection during outdoor activities in public spaces.

Further evidence from the LiveLighter® campaign: A controlled cohort study in Victoria and South Australia.

ISSUE ADDRESSED: The LiveLighter® healthy weight and lifestyle social marketing campaign, developed in Western Australia, employs graphic advertising to communicate negative health effects of overweight and motivate behaviour change. This study extends prior evidence of the effectiveness of the LiveLighter® campaign by evaluating its implementation in a new jurisdiction. METHODS: A controlled cohort design was employed in intervention (Vic) and comparison states (SA), with and without campaign exposure. Population surveys conducted at baseline (BL) (n = 1000 each state), had 75% retention at follow-up (FU) (Vic: n = 715; SA: n = 787). RESULTS: Total campaign awareness was moderate (61.5%). Exposed respondents indicated the campaign was "believable" (91.0%), made a strong argument for reducing weight (87.3%), made them "stop and think" (70.1%), motivated action to reach/stay a healthy weight (59.1%) and was "relevant" (55.6%). The proportion of respondents indicating "toxic fat build up" was a health consequence of overweight increased significantly from BL to FU in Vic and to a lesser extent in SA (Vic:55.7% vs 75.9%; SA:58.1% vs 62.6%, interaction P < .001). The proportion indicating cancer is a health consequence of overweight increased significantly from BL to FU in Vic, but not in SA (Vic:77.1% vs 83.4%; SA:77.8% vs 78.1%, interaction P < .05). CONCLUSIONS: This study extends the evidence base for the LiveLighter® campaign. Sustained campaign activity with clear behavioural recommendations is required to translate improved knowledge into behaviour change. SO WHAT: Evidence-based mass media campaigns can positively impact health behaviours to address the unsustainable increasing burdens of unhealthy weight, dietary risk and inadequate physical activity. A National Obesity Campaign is needed and LiveLighter® is a ready-made, relevant Australian resource.

Differences in healthiness perceptions of food and dietary patterns among the general public and nutrition experts: A cross-sectional online survey.

ISSUES ADDRESSED: Diet quality plays a vital role in the prevention of prevalent non-communicable diseases; however, misperceptions of healthiness of common foods and beverages may be undermining Australians' attempts to maintain a healthy diet. The current study aimed to assess the extent and nature of differences in public and expert opinion in the foods, beverages and dietary patterns that are considered healthy. METHODS: A cross-sectional online survey of 1,097 Victorian adults aged 18-64 and 134 professional dietitians and nutritionists assessed healthiness perceptions of foods, beverages and dietary patterns, self-reported dietary patterns, and factors considered when making healthy choices. Differences in perceptions and dietary patterns between samples and by sex, socio-economic area and level of education were assessed using multivariable logistic regression. RESULTS: There were large discrepancies in which items the public and expert samples considered healthy. Females and those in high socio-economic areas tended to report healthiness perceptions that aligned with the expert sample to a greater degree than their counterparts. Personal judgement of products was important to both samples when making decisions about healthy choices. CONCLUSIONS: The public and expert samples differed greatly in healthiness perceptions with significant variation by demographics. SO WHAT?: Well-funded, sustained public health campaigns are needed to provide the public with evidence-based health and nutrition information and combat persuasive, misleading messaging from popular media and marketing.

Teacher Engagement in Language Teaching: Investigating Self-Efficacy for Teaching Based on the Project "Sino-Greece Online Chinese Language Classrooms".

The support of sustainable learning of foreign languages requires teacher engagement and a high level of self-efficacy, both of which are cornerstones for the persistence of teachers in carrying out teaching activities to help learning. The need for such attributes is even more crucial when online learning platforms as a mode of delivery are becoming increasingly popular. We would argue that keeping students engaged and motivated to attain their academic success online calls for the increased levels of resilience and efforts of teachers. Although self-efficacy of teachers has been widely considered crucial in the professional practices of teachers, there is a paucity of research studies on the self-efficacy of teachers who teach Chinese as a foreign language (CFL) using online platforms. Such a gap becomes prominent after the sudden outbreak of the COVID-19 pandemic, especially in places where there are now numerous calls for online CFL classes. In order to fill in this gap, this study was conducted with a frontline CFL teacher as the participant and aimed to detect thoroughly the trajectories of self-efficacy of a CFL teacher in a completely new teaching context. Embedded in the Project of Sino-Greece Online Chinese Language Classrooms, this study employed narrative inquiry and case study as methodological approaches. Thematic analysis was used to analyze the data that consisted of written narratives (the teacher's teaching journals and reflections, field notes of teaching assistant, and emails of students) and spoken narratives. Three research questions guided this study: What are the teacher's beliefs about (1) the opportunity of teaching CFL online? (2) the management of this online project? (3) her personal capability to foster students' engagement in this project? These three questions focused, respectively, on the three components of the self-efficacy system of a teacher (personal efficacy, efficacy within the organization, and professional efficacy). Findings illustrated that the efficacy beliefs of the teacher in these three aspects were at different levels, which resulted from the interplay of external and internal factors; when external factors appeared to be negative, internal factors seemed to play an essential role.

Can point-of-sale nutrition information encourage reduced preference for sugary drinks among adolescents?

OBJECTIVE: To test whether point-of-sale (POS) information about the nutrition content of sugar-sweetened beverages (SSB) promotes healthier drink choices among teenagers, and explore whether POS intervention effects vary based on prior exposure to a sugary drink public health campaign (13 Cancers). DESIGN: Between-subjects online experiment with three POS signage conditions: no signage (control); sugar content (SC) and Health Star Rating (HSR). Participants viewed their assigned POS sign alone, then alongside a drinks product display and chose which drink they would buy. Perceptions of various drink products and campaign recall were assessed. SETTING: Australia. PARTICIPANTS: Adolescents aged 13-17 years (n 925) recruited via an online panel. RESULTS: POS signs did not promote a significant reduction in preference for SSB (cf. control condition). Cognitive and emotional responses to POS signs were strongest for the SC sign, which was rated higher than the HSR sign on various perceived effectiveness measures. Participants who saw the SC sign rated SSB as less healthy (cf. control condition) and were more likely to accurately estimate the number of teaspoons of sugar in soft drink (cf. HSR sign and control conditions). There was no significant interaction between prior exposure to the 13 Cancers campaign and POS signage condition regarding preferences for and perceptions of SSB. CONCLUSIONS: SSB POS interventions may not have the desired effect on adolescents' drink preferences. Testing SSB POS signs in real-world retail settings is needed to determine whether positive educational impacts extend to promoting healthier drink purchases and reduced SSB consumption among teenagers.

Sugary drink advertising expenditure across Australian media channels 2016-2018.

OBJECTIVE: The aim of this study was to describe advertising expenditure for sugary drinks compared with alternative cold non-alcoholic beverages (artificially sweetened beverages, plain water, plain milk) between 2016 and 2018 across Australian media channels. METHODS: Monthly estimates of advertising expenditure for non-alcoholic beverages were obtained from Nielsen Media and aggregated by product type and media. RESULTS: Total sugary drink advertising expenditure between 2016 and 2018 ($129.5M) significantly exceeded expenditure on artificially sweetened drinks ($23.26M), plain water ($14.27M), and plain milk ($31.30M). Television and out-of-home advertising accounted for the largest share of sugary drink advertising (45%, 35%). Expenditure on out-of-home advertising was more heavily dominated by sugary drinks (75%) than advertising in all media combined (65%). Sugary drink advertising peaked in warmer months and was lowest in August. Soft drinks (26%), flavoured milks (24%) and energy drinks (21%) accounted for the majority of sugary drink advertising. CONCLUSIONS: Cold non-alcoholic beverage advertising in Australian media is dominated by the advertising of sugary drinks. Implications for public health: Restricting unhealthy beverage advertising on television and out-of-home media may be most effective initially. However, comprehensive restrictions capturing a broader range of media and settings would be optimal to prevent displacement and limit advertising reach and exposure.

General and specific graphic health warning labels reduce willingness to consume sugar-sweetened beverages.

Sugar-sweetened beverage (SSB) consumption is associated with obesity and other severe negative health consequences. The present study examined the effectiveness of two types of health warning labels (HWLs) in modulating dietary choices for SSBs: specific HWLs, presenting health consequences associated with consuming SSBs, and general HWLs, presenting health consequences of an unhealthy diet and obesity. While electroencephalography (EEG) was recorded, 63 participants completed a computer-based task in which they were first randomly allocated to view either SBB-specific, general, or non-warning control HWLs. They then viewed images of a range of SSB products, varying on perceived healthiness and tastiness, and rated their willingness to consume (WTC) each one. Linear mixed-effect model analyses revealed that general and specific HWLs both decreased WTC SSBs perceived as tasty, compared to the control condition. For general HWLs, this effect was reduced for SSBs perceived to be healthy, suggesting that specific HWLs may be more effective at reducing SSB consumption. The EEG data showed that SSBs considered unhealthy elicited greater N1 amplitudes, and tasty SSBs elicited greater late positive potential (LPP) amplitudes, possibly reflecting attentional allocation and craving responses, respectively. However, no strong differences between HWL types were found. Taken together, the results suggest that graphic HWLs, both general and specific, have the potential to reduce SSB consumption, but they do not strongly modulate craving-related neural responses to SSBs.

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.
