A values-alignment intervention protects adolescents from the effects of food marketing

The impact of "pinkwashed" alcohol advertisements on attitudes and beliefs: A randomized experiment with US adults

OBJECTIVE

To examine the impact of alcohol advertisements related to breast cancer awareness or charities (i.e., pinkwashed ads) on attitudes and beliefs.

METHODS

In 2023, an online experiment randomized 602 US adults to view three pinkwashed ads for beer, wine, and liquor, or three standard ads for the same products.

RESULTS

Breast cancer risk perceptions (average differential effect [ADE] = 0.03; p = 0.58)) and intentions to purchase the advertised product (ADE = -0.01, p = 0.95) did not differ by ad type. When informed about the link between alcohol and breast cancer, participants who viewed pinkwashed ads reported the ads were more misleading (ADE = 0.51, p < 0.001) and had stronger support for requiring alcohol breast cancer warnings (ADE = 0.23, p < 0.001). The pinkwashed ads for beer (but not for wine or liquor) led to greater: perceived product healthfulness (ADE = 0.16, p = 0.03), perceived social responsibility of the company (ADE = 0.18, p = 0.02), and favorable brand attitudes (ADE = 0.14, p = 0.03).

CONCLUSIONS

Informing the public about pinkwashing increases perceptions of misleadingness and support for alcohol policies.

POLICY IMPLICATIONS

Exposing the industry practice of pinkwashing could be a promising theme for campaigns to reduce alcohol consumption and increase support for alcohol policies.

Coffee Consumption Among Adolescents: A Cross-Sectional Study

The purpose of this cross-sectional study is to analyze and perform a model analysis of the scope of caffeine consumption in adolescents in Turkey. The prevalence of caffeine consumption was 65.5% (321/490), with 22% of boys and 38.45% of girls consuming foodstuffs or beverages containing it. The mean daily caffeine intake was 85.8 mg. Girls consumed all types of coffee more frequently, while boys consumed black tea and energy drinks such as Red Bull and Burn more frequently than girls. Coffee was most frequently consumed to boost concentration, and tea and energy drinks out of habit. Individuals who lived in the city center, smokers, and individuals with high income levels consumed more caffeine (P = .000, P = .000, and P = .000). The level at which energy drinks were consumed by mixing with alcohol in a party setting was 11.5%, and this was more common among boys (P = .000). Greater efforts should be made to inform parents and adolescents of the potential harm resulting from misuse of caffeine.

Development of food literacy in children and adolescents: implications for the design of strategies to promote healthier and more sustainable diets

Food literacy has emerged as a key individual trait to promote the transformation of food systems toward healthy and sustainable diets. Childhood and adolescence are key periods for establishing the foundations of eating habits. Different food literacy competencies are acquired as children develop different cognitive abilities, skills, and experiences, contributing to the development of critical tools that allow them to navigate a complex food system. Thus, the design and implementation of programs to support the development of food literacy from early childhood can contribute to healthier and more sustainable eating habits. In this context, the aim of the present narrative review is to provide an in-depth description of how different food literacy competencies are developed in childhood and adolescence, integrating the extensive body of evidence on cognitive, social, and food-related development. Implications for the development of multisectoral strategies to target the multidimensional nature of food literacy and promote the development of the 3 types of competencies (relational, functional, and critical) are discussed.

Obesity-Related Knowledge and Practice Among the Healthcare Professions Students in Saudi Arabia

Objective

The objectives of this study are to identify the prevalence and the factors behind overweight and obesity among the healthcare profession's students.

Methods

A well-structured and validated questionnaire was distributed to a heterogeneous purposive sample of the healthcare profession's students in Saudi Arabia.

Results

About 21.0% and 15.5% were overweight and obese, respectively. The average knowledge score was 70.6% and increased with age and among obese participants. The average attitude score was 74.8% with no variation within age, body mass index (BMI), and gender. The average practice score was only 36.7%. There was a significant variation of the practice within the different age groups (P = 0.021). There was a significant association between the participant's knowledge and attitude, and practice.

Conclusion

The average practice score was poor. Despite their good knowledge and positive attitude, the students are exposed to heavy junk food marketing, which encourages overconsumption by instilling positive emotional associations with the junk food. They are mostly physically inactive, anxious and sleep deprived, which can lead to poor eating habits. For this group, various strategies and motivators will likely be needed.

'Odds Are: They Win': a disruptive messaging innovation for challenging harmful products and practices of the gambling industry

OBJECTIVE

This paper presents an evidence informed rationale for focussing on harmful gambling products and industry practices in public health messaging through the example of a recent innovation called 'Odds Are: They Win'.

METHODS

'Odds Are: They Win' was initially developed through coproduction involving public health professionals and people with lived experience of gambling harms and implemented across a city-region area. A review of relevant evidence was undertaken, upon which the research team reflected to draw out the implications of 'Odds Are: They Win' for gambling harms messaging.

RESULTS

Evidence is mounting that safer gambling campaigns framed in terms of individual responsibility are ineffective and can generate stigma. 'Odds Are: They Win' presents an alternative focus that is not anti-gambling but raises awareness of industry manipulation of the situational and structural context of gambling. This is in-keeping with historical lessons from the stop smoking field and emerging research in critical health literacy. The latter highlights the potential of education on the social and commercial determinants of health to stimulate behaviour change and collective action.

CONCLUSION

'Odds Are: They Win' is a potentially disruptive innovation for the gambling harms field. Research is required to robustly evaluate this intervention across diverse criteria, target audiences, and delivery settings.

Effect of an action-research nutrition intervention on the Global Diet Quality Score of Colombian adolescents

Strategies to address the nutritional needs of adolescent girls and young women often focus on supplementation. In this study, an action-research approach involving a nutrition education and entrepreneurship intervention was carried out among adolescent girls and young women in poor neighborhoods of Medellín, Colombia. The intervention group significantly increased its intake of several nutrients, including energy, protein, total fat, saturated fat, monounsaturated fat, polyunsaturated fat, cholesterol, dietary fiber, calcium, zinc, and vitamins A, B2, B3, B9, and C. A significant increase was observed in the intake of the Global Diet Quality Score (GDQS) healthy food groups (other fruits, other vegetables, legumes, high-fat dairy products), accompanied by a decrease in the consumption of some unhealthy food groups (sweets and ice creams). A multivariate regression controlling for age, socioeconomic status, occupation, Household Hunger Scale, mean probability of adequacy, physical activity, and body self-perception showed that the nutrition intervention improved the total GDQS by 33% in the intervention group-a substantial improvement notwithstanding the study group's precarious social and economic conditions. We conclude that nutrition education and entrepreneurship models based on this approach may improve the dietary profile of this population and reduce future pressures from nutrition-related chronic diseases.

Mobilizing adolescents and young women to promote healthy diets in urban settings of Colombia and Vietnam: Lessons from two action-research programs

Adolescent and young women face grave nutrition challenges, but limited evidence exists on solutions to improve their diets. Action-research was done over 3 years (2020-2022) in secondary cities of Colombia (Medellin) and Vietnam (Thai Nguyen) to identify nutrient deficits in adolescent and young women diets; elaborate food-based recommendations to improve their nutritional status using Optifood linear programming; and engage respondents in incorporating suggested recommendations to their diet using a Social Innovation Challenge approach. A total of 1001 respondents were interviewed in Vietnam, 793 in Colombia. The probability of nutrient inadequacy in both locations was highest for iron and calcium, followed by the risk of deficiency for several other vitamins and minerals. Social Innovation Challenge teams (11 in Vietnam, 9 in Colombia) were created and supported in developing solutions to improve diets and tackle those deficiencies. Awards and resources were transferred to the most promising solutions to enable their implementation. Pre/post measurements of the interventions' impact using the Global Diet Quality Score as outcome metric showed significant improvement in the diets of Challenge participants. After introducing a series of companion articles that offer detailed results on those various steps, this paper draws strategic lessons from an action-research perspective.

Women Consumers' Views on Legislation to Restrict Prominent Placement and Multibuy Promotions of High Fat, Sugar, and Salt Products in England: A Qualitative Perspective

BACKGROUND

As part of the childhood obesity strategy, the UK Government has introduced regulations to restrict the ways high fat salt and sugar (HFSS) products can be promoted in retail settings from October 2022. This study explored (i) consumers' views on the likely impact of the UK legislation restricting the placement and promotion of HFSS products on their shopping behaviours and (ii) consumers' beliefs about who is responsible for healthy eating.

METHODS

Using a cross-sectional study design, qualitative semi-structured telephone interviews were conducted with a purposive sample of women who shopped at a discount supermarket. Thematic analysis was employed to identify key themes.

RESULTS

Participants' (n = 34) had a median age of 35 years and over half were in paid employment. Five themes were identified: (1) The legislation is acceptable, but people can still (and should be able to) buy HFSS items; (2) The legislation is likely to have more impact on shoppers who do not plan their shopping; (3) Affordability of healthy food is just as, or more, important than the legislation; (4) It's up to the individual to eat healthily; and (5) Government and retailers can better support consumers to make healthy choices.

CONCLUSION

Most participants were optimistic about the incoming regulations and believed that it would support consumers to make healthier food choices. Many raised concerns, however, that the high price of healthy foods and continued availability of unhealthy foods within the stores could undermine the legislation's benefits. Coupling the legislation with interventions to promote and reduce the costs of healthier products would go some way to ensure its success. Raising awareness about marketing strategies that play into consumer concerns for cost and autonomy could further increase acceptance of the policy.

Shifting the mindset culture to address global educational disparities

Educational outcomes remain highly unequal within and across nations. Students' mindsets-their beliefs about whether intellectual abilities can be developed-have been identified as a potential lever for making adolescents' academic outcomes more equitable. Recent research, however, suggests that intervention programs aimed at changing students' mindsets should be supplemented by programs aimed at the changing the mindset culture, which is defined as the shared set of beliefs about learning in a school or classroom. This paper reviews the theoretical and empirical origin of the mindset culture and examines its potential to reduce group-based inequalities in education. In particular, experiments have identified two broad ways the mindset culture is communicated by teachers: via informal messages about growth (e.g., that all students will be helped to learn and succeed), and formal opportunities to improve (e.g., learning-focused grading policies and opportunities to revise and earn credit). New field experiments, applying techniques from behavioral science, have also revealed effective ways to influence teachers' culture-creating behaviors. This paper describes recent breakthroughs in the U.S. educational context and discusses how lessons from these studies might be applied in future, global collaborations with researchers and practitioners.

Beyond Plants: The Ultra-Processing of Global Diets Is Harming the Health of People, Places, and Planet

Global food systems are a central issue for personal and planetary health in the Anthropocene. One aspect of major concern is the dramatic global spread of ultra-processed convenience foods in the last 75 years, which is linked with the rising human burden of disease and growing sustainability and environmental health challenges. However, there are also calls to radically transform global food systems, from animal to plant-derived protein sources, which may have unintended consequences. Commercial entities have moved toward this "great plant transition" with vigor. Whether motivated by profit or genuine environmental concern, this effort has facilitated the emergence of novel ultra-processed "plant-based" commercial products devoid of nutrients and fiber, and sometimes inclusive of high sugar, industrial fats, and synthetic additives. These and other ingredients combined into "plant-based" foods are often assumed to be healthy and lower in calorie content. However, the available evidence indicates that many of these products can potentially compromise health at all scales-of people, places, and planet. In this viewpoint, we summarize and reflect on the evidence and discussions presented at the Nova Network planetary health meeting on the "Future of Food", which had a particular focus on the encroachment of ultra-processed foods into the global food supply, including the plant-sourced animal protein alternatives (and the collective of ingredients therein) that are finding their way into global fast-food chains. We contend that while there has been much uncritical media attention given to the environmental impact of protein and macronutrient sources-meat vs. novel soy/pea protein burgers, etc.-the impact of the heavy industrial processing on both human and environmental health is significant but often overlooked, including effects on cognition and mental health. This calls for a more nuanced discourse that considers these complexities and refocuses priorities and value systems towards mutualistic solutions, with co-benefits for individuals, local communities, and global ecology.

A values-aligned intervention fosters growth mindset-supportive teaching and reduces inequality in educational outcomes

Group-based educational disparities are smaller in classrooms where teachers express a belief that students can improve their abilities. However, a scalable method for motivating teachers to adopt such growth mindset-supportive teaching practices has remained elusive. In part, this is because teachers often already face overwhelming demands on their time and attention and have reason to be skeptical of the professional development advice they receive from researchers and other experts. We designed an intervention that overcame these obstacles and successfully motivated high-school teachers to adopt specific practices that support students' growth mindsets. The intervention used the values-alignment approach. This approach motivates behavioral change by framing a desired behavior as aligned with a core value-one that is an important criterion for status and admiration in the relevant social reference group. First, using qualitative interviews and a nationally representative survey of teachers, we identified a relevant core value: inspiring students' enthusiastic engagement with learning. Next, we designed a ~45-min, self-administered, online intervention that persuaded teachers to view growth mindset-supportive practices as a way to foster such student engagement and thus live up to that value. We randomly assigned 155 teachers (5,393 students) to receive the intervention and 164 teachers (6,167 students) to receive a control module. The growth mindset-supportive teaching intervention successfully promoted teachers' adoption of the suggested practices, overcoming major barriers to changing teachers' classroom practices that other scalable approaches have failed to surmount. The intervention also substantially improved student achievement in socioeconomically disadvantaged classes, reducing inequality in educational outcomes.

The Founder: Dispositional Greed, Showbiz, and the Commercial Determinants of Health

Marketing unhealthy products by multinational corporations has caused considerable harm to individual health, collective wellbeing, and environmental sustainability. This is a growing threat to all societies and a significant contributor to the rising global burden of non-communicable diseases and early mortality. While there is growing consideration of the commercial determinants of health, this is largely focused on the methods by which unhealthy products are marketed and disseminated, including efforts to manipulate policy. Little attention has been paid to the underlying psychological traits and worldviews that are driving corporate greed. Here, we consider the role of "dispositional greed" in the commercial determinants of health with a focus on the historical attitudes and culture in the ultra-processed food industry-exemplified by "The Founder" of the McDonald's franchise. We argue that greed and associated psychological constructs, such as social dominance orientation and collective narcissism, permeate the commercial determinants of health at a collective level. This includes how a culture of greed within organizations, and individual dispositional greed, can magnify and cluster at scale, perpetuated by social dominance orientation. We also consider the ways in which "showbiz" marketing specifically targets marginalized populations and vulnerable groups, including children-in ways that are justified, or even celebrated despite clear links to non-communicable diseases and increased mortality. Finally, we consider how greed and exploitative mindsets mirror cultural values and priorities, with trends for increasing collective narcissism at scale, recognizing that many of these attitudes are cultivated in early life. A healthier future will depend on navigating a path that balances material prosperity with physical and spiritual wellbeing. This will require cultural change that places higher value on kindness, reciprocity, and mutualistic values especially in early life, for more equitable flourishing.

What Were the Information Voids? A Qualitative Analysis of Questions Asked by Dear Pandemic Readers between August 2020-August 2021

In the current infodemic, how individuals receive information (channel), who it is coming from (source), and how it is framed can have an important effect on COVID-19 related mitigation behaviors. In light of these challenges presented by the infodemic, Dear Pandemic (DP) was created to directly address persistent questions related to COVID-19 and other health topics in the online environment. This is a qualitative analysis of 3806 questions that were submitted by DP readers to a question box on the Dear Pandemic website between August 30, 2020 and August 29, 2021. Analyses resulted in four themes: the need for clarification of other sources; lack of trust in information; recognition of possible misinformation; and questions on personal decision-making. Each theme reflects an unmet informational need of Dear Pandemic readers, which may be reflective of the broader informational gaps in our science communication efforts.This study highlights the role of an ad hoc risk communication platform in the current environment and uses questions submitted to the Dear Pandemic question box to identify informational needs of DP readers over the course of the COVID-19 pandemic. These findings may help clarify how organizations addressing health misinformation in the digital space can contribute to timely, responsive science communication and improve future communication efforts.

"I'm not here to push you:" raising adolescents' treatment engagement via autonomy support

More than 45% of adolescents with aggressive behavior problems drop out of treatment prematurely. Building on insights from self-determination theory, we examined in three studies whether clinicians can raise adolescents' treatment engagement by supporting their autonomy. In an interview study (Study 1), clinicians (N = 16; 43.8% female; ages 30-57) spontaneously described 12 times more autonomy-supportive than controlling strategies to engage adolescents. In a preregistered experiment (Study 2), clinicians (N = 68; 88.2% female; ages 23-65) were confronted with videos of adolescents displaying resistance. We manipulated the DSM diagnosis of adolescents to indicate either aggressive behavior problems or other problems. We found that, regardless of diagnosis, clinicians used both autonomy-supportive strategies (57.7% of responses) and controlling strategies (39.3%), suggesting that applying autonomy support can be challenging with any adolescent displaying resistance. In an experimental study (Study 3), adolescents (N = 252; 50.0% female; ages 12-17) reported higher therapeutic alliance (d = 0.95, 95% CI [0.80, 1.10]) and treatment engagement (d = 0.77, 95% CI [0.63, 0.91]) after listening to audio-recorded autonomy-supportive versus controlling responses from clinicians, regardless of whether these adolescents had aggressive behavior problems. Overall, this research suggests that clinicians can raise adolescents' treatment engagement through autonomy support.

Impact of Health, Environmental, and Animal Welfare Messages Discouraging Red Meat Consumption: An Online Randomized Experiment

BACKGROUND

Reducing red meat consumption is a key strategy for curbing diet-related chronic diseases and mitigating environmental harms from livestock farming. Messaging interventions aiming to reduce red meat consumption have focused on communicating the animal welfare, health, or environmental harms of red meat. Despite the popularity of these 3 approaches, it remains unknown which is most effective, as limited studies have compared them side by side.

OBJECTIVE

Our aim was to evaluate responses to red-meat-reduction messages describing animal welfare, health, or environmental harms.

DESIGN

This was an online randomized experiment.

PARTICIPANTS

In August 2021, a convenience sample of US adults was recruited via an online panel to complete a survey (n = 2,773 nonvegetarians and vegans were included in primary analyses).

INTERVENTION

Participants were randomly assigned to view 1 of the 4 following messages: control (neutral, non-red meat message), animal welfare, health, or environmental red-meat-reduction messages.

MAIN OUTCOME MEASURES

After viewing their assigned message, participants ordered hypothetical meals from 2 restaurants (1 full service and 1 quick service) and rated message reactions, perceptions, and intentions.

STATISTICAL ANALYSES PERFORMED

Logistic and linear regressions were performed.

RESULTS

Compared with the control message, exposure to the health and environmental red-meat-reduction messages reduced red meat selection from the full-service restaurant by 6.0 and 8.8 percentage points, respectively (P = .02 and P < .001, respectively), while the animal welfare message did not (reduction of 3.3 percentage points, P = .20). None of the red-meat-reduction messages affected red meat selection from the quick-service restaurant. All 3 red-meat-reduction messages elicited beneficial effects on key predictors of behavior change, including emotions and thinking about harms.

CONCLUSIONS

Red-meat-reduction messages, especially those describing health or environmental harms, hold promise for reducing red meat selection in some types of restaurants. Additional interventions may be needed to discourage red meat selection across a wider variety of restaurants, for example, by making salient which menu items contain red meat.

The Impact of Modifying Food Service Practices in Secondary Schools Providing a Routine Meal Service on Student's Food Behaviours, Health and Dining Experience: A Systematic Review and Meta-Analysis

The education sector is recognised as an ideal platform to promote good nutrition and decision making around food and eating. Examining adolescents in this setting is important because of the unique features of adolescence compared to younger childhood. This systematic review and meta-analysis examine interventions in secondary schools that provide a routine meal service and the impact on adolescents’ food behaviours, health and dining experience in this setting. The review was guided by Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) Checklist and Cochrane Handbook recommendations. Studies published in English searched in four databases and a hand search yielded 42 interventions in 35 studies. Risk of bias was assessed independently by two reviewers. Interventions were classified using the NOURISHING framework, and their impact analysed using meta-analysis, vote-counting synthesis or narrative summary. The meta-analysis showed an improvement in students selecting vegetables (odds ratio (OR): 1.39; 1.12 to 1.23; p = 0.002), fruit serves selected (mean difference (MD): 0.09; 0.09 to 0.09; p < 0.001) and consumed (MD: 0.10; 0.04 to 0.15; p < 0.001), and vegetable serves consumed (MD: 0.06; 0.01 to 0.10; p = 0.024). Vote-counting showed a positive impact for most interventions that measured selection (15 of 25; 41% to 77%; p = 0.002) and consumption (14 of 24; 39% to 76%; p = 0.013) of a meal component. Interventions that integrate improving menu quality, assess palatability, accessibility of healthier options, and student engagement can enhance success. These results should be interpreted with caution as most studies were not methodologically strong and at higher risk of bias. There is a need for higher quality pragmatic trials, strategies to build and measure sustained change, and evaluation of end-user attitudes and perceptions towards intervention components and implementation for greater insight into intervention success and future directions (PROSPERO registration: CRD42020167133).

A synergistic mindsets intervention protects adolescents from stress

Social-evaluative stressors-experiences in which people feel they could be judged negatively-pose a major threat to adolescent mental health1-3 and can cause young people to disengage from stressful pursuits, resulting in missed opportunities to acquire valuable skills. Here we show that replicable benefits for the stress responses of adolescents can be achieved with a short (around 30-min), scalable 'synergistic mindsets' intervention. This intervention, which is a self-administered online training module, synergistically targets both growth mindsets4 (the idea that intelligence can be developed) and stress-can-be-enhancing mindsets5 (the idea that one's physiological stress response can fuel optimal performance). In six double-blind, randomized, controlled experiments that were conducted with secondary and post-secondary students in the United States, the synergistic mindsets intervention improved stress-related cognitions (study 1, n = 2,717; study 2, n = 755), cardiovascular reactivity (study 3, n = 160; study 4, n = 200), daily cortisol levels (study 5, n = 118 students, n = 1,213 observations), psychological well-being (studies 4 and 5), academic success (study 5) and anxiety symptoms during the 2020 COVID-19 lockdowns (study 6, n = 341). Heterogeneity analyses (studies 3, 5 and 6) and a four-cell experiment (study 4) showed that the benefits of the intervention depended on addressing both mindsets-growth and stress-synergistically. Confidence in these conclusions comes from a conservative, Bayesian machine-learning statistical method for detecting heterogeneous effects6. Thus, our research has identified a treatment for adolescent stress that could, in principle, be scaled nationally at low cost.

'Even if you don't pay attention to it, you know it's there': A qualitative exploration of adolescents' experiences with digital food marketing

Adolescents are particularly vulnerable to digital food marketing. However, research on adolescents' recall, awareness, and opinions of this type of marketing is still scarce. Accordingly, the present study aimed to conduct an in-depth examination of adolescents' experiences with digital food marketing. A convenience sample of 209 adolescents was recruited at two private educational institutions and a public health facility in Montevideo, the capital city of Uruguay. Semi-structured group interviews were conducted, recorded in audio and transcribed. The transcripts were analyzed using content analysis based on a deductive-inductive approach. Results showed that participants were highly exposed to digital food marketing, as they all remembered having seen advertisements, with those of fast-food restaurants and food-ordering apps being the most frequently mentioned. According to the adolescents' accounts, images, colors, music, oversized portions, product novelty, price promotions and celebrities were the most memorable aspects of food advertisements. Participants recognized the effect of advertisements on product awareness and wanting, and, to a lesser extent, on actual purchase and consumption behavior. Factors that were thought to mediate the impact of digital marketing on food choice were also identified. In the final part of the interviews, participants proposed strategies to reduce the effect of digital marketing on their food choices, which included both regulatory approaches to reduce exposure to digital marketing of unhealthy foods and behavior change communication. Together, the current findings provide insights for the development of multifaceted strategies to reduce the effects of digital food marketing on the eating habits of adolescents.

A Quasi-Experimental Intervention Trial: Testing the Efficacy of Attitudinal Inoculation Videos to Enhance COVID-19 Vaccine Acceptance

BACKGROUND

Over the course of the COVID-19 pandemic, a variety of COVID-19 related misinformation has spread and been amplified online. The spread of misinformation can influence COVID-19 beliefs and protective actions including vaccine hesitancy. Belief in vaccine misinformation is associated with lower vaccination rates and higher vaccine resistance. Attitudinal inoculation is a preventative approach to combating misinformation and disinformation which leverages the power of narrative, rhetoric, values, and emotion.

OBJECTIVE

This study seeks to test inoculation messages in the form of short video messages to promote resistance against persuasion by COVID-19 vaccine misinformation.

METHODS

We designed a series of 30-second inoculation videos and conducted a quasi-experimental study to test the use of attitudinal inoculation in a population of individuals who were unvaccinated (N = 1991). The three intervention videos were distinguished by their script design- with Intervention Video 1 focusing on narrative/rhetorical ("Narrative") presentation of information, Intervention Video 2 focusing on delivering a fact-based information ("Fact"), and Intervention Video 3 using a hybrid design ("Hybrid"). Analysis of covariance (ANCOVA) models were used to compare the main effect of intervention group on the three outcome variables: ability to recognize misinformation tactics ("Recognize", willingness to share misinformation ("Share"), and willingness to take the COVID-19 vaccine ("Willingness").

RESULTS

There were significant effects across all three outcome variables comparing inoculation intervention groups to controls. For the Recognize outcome, the ability to recognize rhetorical strategies, there was a significant intervention group effect (P<.001). For the Share outcome, support for sharing the mis-disinformation, the intervention group main effect was statistically significant ( P=.017). For the Willingness outcome, there was a significant intervention group effect; intervention groups were more willing to get the COVID-19 vaccine compared to controls ( P=.006).

CONCLUSIONS

Across all intervention groups, inoculated individuals showed greater resistance to misinformation than their non-inoculated counterparts. Relative to those who were not inoculated, inoculated participants showed significantly greater ability to recognize and identify rhetorical strategies used in misinformation, were less likely to share false information, and had greater willingness to get the COVID-19 vaccine. Attitudinal inoculation delivered through short video messages should be tested in public health messaging campaigns to counter mis-disinformation.

CLINICALTRIAL

Toward a Recipe for Deep versus Surface Level Tailoring: Mixed-Methods Validation of Message Features to Reduce Sugary Beverage Consumption

Targeted marketing contributes to the overconsumption of sugary beverages, which contributes to obesity and diabetes disparities among African American and Latino populations in the U.S. Health communicators can similarly use culturally tailored messages to decrease sugary beverage consumption among these groups, yet the specific strategies to operationalize cultural tailoring-the message components essential for such tailoring-are ill-described. We sought to identify and validate authentically created, culturally tailored messages using a multiple step mixed-methods approach. First, we used a snowball approach to identify nutrition education messages targeting ethnic minorities about reducing sugary beverage consumption (N = 85). Via content analysis, we assessed message features (character gender and race/ethnicity), level of change of the appeal (individual or social), and level of cultural tailoring (surface level tailoring in the form of matching character gender and race/ethnicity with target audience versus deep structural tailoring in the form of appealing to values is an effective message strategy). The highest-rated videos were then validated by a sample of the target audience using a quantitative survey and qualitative comments (N = 76). The results inform theorizing on message tailoring and provide a validated pool of culturally relevant messages intended both to reduce intentions to consume sugary beverages and to engage in social change actions.

Protocol: Effectiveness of message content and format on individual and collective efficacy in reducing the intention to consume sugar-sweetened beverages

The strategic use of media is a common approach to promote health. A large body of evidence identifies specific features that increase message efficacy, including tailoring messages to the target audience and using a storytelling format. Yet most message testing research has focused on individual-level outcomes, ignoring the social and environmental determinants of health behaviors, which require collective action and political will to change. Grounded in an ecological approach to communication, we will carry out two double-blinded randomized experiments to test the relative effectiveness of message tailoring (culturally-tailored vs. standard) and format (narrative vs. didactic) to increase the intention to reduce individual sugar-sweetened beverage consumption, the understanding of social and commercial determinants of health, and the sense of empowerment among young adult Latinas. Based on power analyses (80% power at alpha = 0.05), we will randomize 438 participants to two groups (traditional standard infographic and culturally-tailored infographic) in the first study, and 662 participants to two groups (culturally-tailored infographic and culturally-tailored comic book) in the second study. All participants will be measured by a pre-treatment test and an immediate post-treatment test. We hypothesize that culturally-tailored comic book will be most effective, and traditional standard infographic will be least effective, on all levels of outcomes. This study will provide empirical evidence in communication strategies to help young Latinos or other racial/ethnic minority young people to pursue positive dietary behaviors that both benefit themselves and contribute to change of social norms.

Distilling the curriculum: An analysis of alcohol industry-funded school-based youth education programmes

BACKGROUND AND AIM

For decades, corporations such as the tobacco and fossil fuel industries have used youth education programmes and schools to disseminate discourses, ideas and values favourable to their positions, and to pre-empt regulation that threatens profits. However, there is no systematic research into alcohol industry-funded youth education programmes. This article serves to address this important gap in the literature.

METHODS

Using a discourse theoretical approach informed by poststructural discourse theory and critical discourse analysis, we analysed teaching materials from three school-based youth education initiatives which focus on alcohol consumption and health harms: Drinkaware for Education, The Smashed Project (funded by Diageo), and Talk About Alcohol (Alcohol Education Trust). These materials, some of which are disseminated internationally, are provided to schools through intermediary bodies in receipt of alcohol industry funding.

FINDINGS

The analysis found that these materials drew from and presented discourses of personal responsibility, moderate alcohol consumption, and involved a narrowing of the problem definition and causes. The locus of the problem is located by the discourses within individuals including youth, with causes of youth alcohol consumption repeatedly presented as peer pressure and 'poor choices', with little or no mention of alcohol industry marketing or other practices. All programmes promoted familiarisation and normalisation of alcohol as a 'normal' adult consumer product which children must learn about and master how to use responsibly when older. The discourses constructed in these materials closely align with those of other alcohol industry corporate social responsibility discourses which employ selective presentation of harms, including misinformation about cancer, and ambiguous terms such as "responsible drinking". Furthermore, the role of alcohol price, availability and access, and the impacts of alcohol and the industry on inequities were not articulated within the discourses. The research was limited to an analysis of teaching materials and further research is needed to explore their impact on youth, teachers and wider discourses and social norms.

CONCLUSION

Alcohol industry-sponsored youth education programmes serve industry interests and promote moderate consumption while purportedly educating children about harms and influences of alcohol use. There are considerable conflicts of interest in the delivery of alcohol education programmes funded by the alcohol industry and intermediary bodies in receipt of such funding. Alcohol education materials should be developed independent from industry, including funding, and should empower children and young people to understand and think critically about alcohol, including harms and drivers of consumption, and effective interventions needed to protect them and others from alcohol-related harms. Independent organisations can use this analysis to critique their materials to strengthen alignment with meeting student and public health interests. The ongoing exposure of children and young people to such conflicted and misleading materials needs urgent attention from policymakers, practitioners, teachers and parents, and resources dependent on industry support should cease being used in schools.

Techniques for Advertising Healthy Food in School Settings to Increase Fruit and Vegetable Consumption

Background

Childhood obesity rates in Western developed countries are rapidly increasing. While research shows that eating more fruits and vegetables (FV) is a preventive measure, children do not eat adequate amounts of FV. Marketing of high salt, fat, and sugar foods influences children’s eating behaviors, decreases FV consumption, and is prevalent in children’s surroundings. Garnering the power of ads on children, a potential solution for increasing FV consumption is FV marketing/advertising. Schools can serve as a viable option for testing this advertising because a significant amount of children’s time is spent in school settings. However, research surrounding the use of FV advertising in schools is lacking in a consensus on the most effective methodologies.

Objective

This paper reviewed existing research on FV advertising in schools and proposed directions for future research surrounding methodology and experimental design.

Study Design, Setting, Participants

PubMed and PsycINFO databases were searched with variations of the terms “vegetable,” “marketing,” “advertisements,” “consumption,” and “schools” (eg, “vegetable consumption AND advertisements AND schools”. Study inclusion criteria were: conducted in school settings, used FV marketing as primary intervention, and measured change in FV consumption or preference.

Measurable Outcome/Analysis

This review qualitatively compared the studies’ participant demographics, methodologies, and measures of success, and evaluated the studies’ strengths and weaknesses.

Results

Of the 38 articles reviewed, 8 met the inclusion criteria. Five studies examined elementary school populations; 4 were conducted in cafeterias. Major forms of advertising/interventions were print media, video media, and classroom education interventions, of which print media was the most widely used. Three articles utilized change in consumption of FV as a measure of success, while others measured change in preference. All studies reported increased consumption/preference in at least 1 intervention during or immediately after the intervention. However, only 4 studies conducted follow-up testing.

Conclusion

FV advertisements in schools appear to be effective in increasing FV consumption among children. To develop implementable advertising, future studies should maintain cohesive methodologies by controlling for novelty effects, conducting follow-up testing, and measuring actual FV consumption rather than preference.

Food-Focused Media Literacy for Remotely Acculturating Adolescents and Mothers: A Randomized Controlled Trial of the "JUS Media? Programme"

PURPOSE

Unhealthy eating is a major modifiable risk factor for noncommunicable diseases and obesity, and remote acculturation to U.S. culture is a recently identified cultural determinant of unhealthy eating among adolescents and families in low/middle-income countries. This small-scale randomized controlled trial evaluated the efficacy of the "JUS Media? Programme," a food-focused media literacy intervention promoting healthier eating among remotely acculturating adolescents and mothers in Jamaica.

METHODS

Gender-stratified randomization of 184 eligible early adolescents and mothers in Kingston, Jamaica (i.e., 92 dyads: M_{adolescent.age} = 12.79 years, 51% girls) determined 31 "Workshops-Only" dyads, 30 "Workshops + SMS/texting" dyads, and 31 "No-Intervention-Control" dyads. Nutrition knowledge (food group knowledge), nutrition attitudes (stage of nutritional change), and nutrition behavior (24-hour recall) were primary outcomes assessed at four time points (T1/baseline, T2, T3, T4) across 5 months using repeated measures analysis of covariances.

RESULTS

Compared to control, families in one or both intervention groups demonstrated significantly higher nutrition knowledge (T3 adolescents, T4 mothers: mean differences .79-1.08 on a 0-6 scale, 95% confidence interval [CI] .12-1.95, Cohen's ds = .438-.630); were more prepared to eat fruit daily (T3 adolescents and mothers: .36-.41 on a 1-5 scale, 95% CI .02-.77, ds = .431-.493); and were eating more cooked vegetables (T4 adolescents and T2 and T4 mothers: .20-.26 on a 0-1 scale, 95% CI -.03-.50, ds = .406-.607). Postintervention focus groups (6-month-delay) revealed major positive impacts on participants' health and lives more broadly.

CONCLUSIONS

A food-focused media literacy intervention for remotely acculturating adolescents and mothers can improve nutrition. Replication in Jamaica and extension to the Jamaican diaspora would be useful.

Cultural Variance in Reception and Interpretation of Social Media COVID-19 Disinformation in French-Speaking Regions

Digital communication technology has created a world in which media are capable of crossing national boundaries as never before. As a result, language is increasingly the salient category determining individuals' media consumption. Today, a single social media post can travel around the world, reaching anyone who speaks its language. This poses significant challenges to combatting the spread of disinformation, as an ever-growing pool of disinformation purveyors reach audiences larger than ever before. This dynamic is complicated, however, by the diversity of audience interpretations of message content within a particular language group. Both across and within national boundaries, a single message may be subject to a variety of interpretations depending on the cultural experiences and identities of its recipients. This study explores that dynamic through analysis of French language anti-vaccine and COVID-denialist disinformation. Using qualitative coding methodology, a team of researchers empirically identify common and far-reaching patterns of Francophone COVID disinformation narratives and rhetoric. These narratives and rhetorics are then subjected to hermeneutic close reading to determine likely variations in their reception across different French-speaking cultures. Data were gathered and analyzed between the dates of 24 March 2021 and 27 April 2021. Results of this study indicate the need for awareness on the part of public health officials combatting COVID disinformation online, for both the transnational reach of disinformation targeting speakers of a single language and for variations in meaning and salience across cultures within that language group.

Why We Eat the Way We Do: A Call to Consider Food Culture in Public Health Initiatives

The way we eat has changed dramatically in only a few decades. While definitions of food culture have previously existed, a clear description of modern food culture that can be used for health promotion is lacking. In this paper, we propose a concept of food culture for application within public health, what a positive food culture looks like compared to negative elements that have dominated in developed countries and the consequences for physical and mental health and wellbeing. We support calls to action from the international community to reconsider the way we eat. All segments of society have a role to play in building a positive food culture, and it is critical that macro (policy and systems) and meso (community) level environmental factors align and provide supportive environments that promote health-enhancing behaviours. Defining food culture is a necessary step towards articulating the complexities that influence food behaviours and impact health. The ultimate goal is collective action to enable population-wide and sustained improvements to the way we eat, and how we think and feel about food.

Making sense of adolescent-targeted social media food marketing: A qualitative study of expert views on key definitions, priorities and challenges

Traditional food marketing stimulates adolescents' consumption of energy-dense, nutrient-poor foods. These dietary behaviours may track into adulthood and lead to weight gain, obesity and related non-communicable diseases. While social media use in adolescents has proliferated, little is known about the content of food marketing within these platforms, and how this impacts adolescents' dietary behaviours. This paper aimed to obtain expert insights on factors involved in the association between social media food marketing (SMFM) and adolescent dietary behaviours, and to explore their views on key priorities, challenges and strategies for future SMFM research and policies. One-on-one semi-structured interviews (n = 17) were conducted with experts from Western Europe, Australia and North America, in the fields of public health (policy), nutrition science, social media marketing, adolescent medicine, clinical psychology, behavioural sciences, communication, food industry, social influencing, and social marketing. The experts' collective responses identified that the line between food content posted by social media users and food companies is blurred. Adolescents' processing of SMFM may be mostly implicit, involving social comparison, emotional engagement, and attaching symbolic meanings to foods. Mediating factors and adolescent-specific and SMFM-specific moderating factors potentially influencing adolescents' response to SMFM were summarized in a Social Ecological model. Experts agreed that there is limited scientific evidence on adolescent-targeted SMFM and there are no strict regulations in place to protect adolescents from unhealthy SMFM, while adolescents are active social media users who are cognitively vulnerable to implicit marketing tactics. Adolescent-targeted SMFM should be controlled by encouraging healthy food marketing or limiting junk food marketing. Also, prioritizing both quantitative research on SMFM exposure and its impact, and qualitative research to obtain adolescents' perspectives, is crucial to advocate for regulatory changes regarding adolescent-targeted SMFM content.

Values-Alignment Messaging Boosts Adolescents' Motivation to Control Social Media Use

Two preregistered experiments with 2,733 U.S. high school students (age range = 13-19 years) compared the impact of different messages on adolescents' motivation to control social media use (SMU). A traditional message emphasized the benefits of avoiding SMU, whereas a values-alignment message framed controlling SMU as being consistent with autonomy and social justice. Compared to no message or a traditional message, in both studies, a values-alignment message led to greater motivation to control SMU immediately afterward, and in Study 2, awareness of "addictive" social media designs 3 months later. As hypothesized, values-alignment messaging was more motivating for girls than boys. Results offer preliminary support for leveraging adolescents' drives for autonomy and social justice to motivate self-regulation of SMU.

Development of a Codebook of Online Anti-Vaccination Rhetoric to Manage COVID-19 Vaccine Misinformation

Vaccine hesitancy (delay in obtaining a vaccine, despite availability) represents a significant hurdle to managing the COVID-19 pandemic. Vaccine hesitancy is in part related to the prevalence of anti-vaccine misinformation and disinformation, which are spread through social media and user-generated content platforms. This study uses qualitative coding methodology to identify salient narratives and rhetorical styles common to anti-vaccine and COVID-denialist media. It organizes these narratives and rhetorics according to theme, imagined antagonist, and frequency. Most frequent were narratives centered on “corrupt elites” and rhetorics appealing to the vulnerability of children. The identification of these narratives and rhetorics may assist in developing effective public health messaging campaigns, since narrative and emotion have demonstrated persuasive effectiveness in other public health communication settings.

Energy drink consumption among Australian adolescents associated with a cluster of unhealthy dietary behaviours and short sleep duration

BACKGROUND

Non-alcoholic energy drinks ('energy drinks') are high in sugar, as well as caffeine, leading to concerns regarding their suitability for children and adolescents. Despite this, marketing of energy drinks is often directed at adolescents, and there are no age restrictions on the sale of these products in Australia. The current study aimed to examine patterns in consumption of energy drinks among Australian secondary school students and identify sociodemographic and behavioural correlates associated with regular consumption.

METHODS

Participants were 8942 students in Years 8 to 11 (aged 12 to 17 years) who participated in the 2018 National Secondary Students' Diet and Activity (NaSSDA) cross-sectional survey. A multistage stratified random sampling procedure was used. Within the school setting, students self-completed an online questionnaire assessing their dietary, physical activity and sedentary behaviours. A multilevel logistic regression model was used to examine associations between energy drink consumption and sociodemographic and behavioural factors.

RESULTS

Overall, 8% of students reported consuming energy drinks on a weekly basis ('regular consumers'). A further 16% indicated they consume less than one cup per week of these types of drinks, while around three-quarters (76%) reported they do not consume energy drinks. Regular consumption of energy drinks was independently associated with being male, having greater weekly spending money, high intakes of snack foods, fast food, other sugar-sweetened beverages and fruit juice, as well as short sleep duration. There was no independent association with other sociodemographic characteristics (i.e., year level, level of disadvantage, geographic location), consumption of vegetables and fruit, physical activity level, or sedentary recreational screen time.

CONCLUSIONS

While most Australian adolescents do not consume energy drinks, regular consumption is more prevalent among males, and consumption appears to cluster with other unhealthy dietary behaviours and short sleep duration. Findings support the need for policies that will reach identified at-risk groups (e.g., increased regulation of the marketing and sale of energy drinks), as well as suggest opportunities for interventions targeting energy drink consumption alongside other unhealthy dietary behaviours.

Examining the Correlates of Adolescent Food and Nutrition Knowledge

Food literacy is a set of skills and knowledge that are integral to diet. It is common among teenagers to not have basic food literacy skills needed to consume a healthy diet. This study examined: (1) the current state of food and nutrition knowledge among adolescents 13–19 years of age in the census metropolitan area of London, ON, Canada; and (2) correlates of food knowledge and nutrition knowledge among adolescents. Data for this study were drawn from baseline youth and parent survey data collected from a larger population health intervention study. Statistical analysis of the survey data indicates that higher parental education and higher median neighbourhood family income, the use of mobile health applications, liking to cook, as well as confidence in reading and understanding food labels were all consistently associated with increased food and nutrition knowledge. Findings may help guide future research towards optimal methods for delivering food literacy interventions to effectively educate teenagers. Results of this study may help guide policy makers, researchers, and public health professionals in developing appropriate food and nutrition programs and curriculums to combat the decline in food literacy skills.

How do we harness adolescent values in designing health behaviour change interventions? A qualitative study

OBJECTIVES

Adolescent health behaviours do not support optimal development. Adolescents are reportedly difficult to engage in health behaviour improvement initiatives. Little is known about what adolescents value in relation to diet and physical activity or how best to target these in health interventions. This study explored adolescents' values in relation to diet and physical activity and how these values can inform health intervention design.

DESIGN

Qualitative semi-structured interviews explored adolescents' lives, what they thought about diet and physical activity and what might support them to improve their health behaviours.

METHODS

A total of 13 group interviews were conducted with 54 adolescents aged 13-14 years, of whom 49% were girls and 95% identified as White British. Participants were recruited from a non-selective secondary school in a large southern UK city. Inductive thematic analysis was used to identify key adolescent values.

RESULTS

Adolescents valued being with their friends, doing what they enjoyed and were good at; being healthy was important to them but only if achievable without compromising other things that are important to them. The need to be healthy was not aligned with adolescents' basic psychological needs, nor their strongly held priorities and values.

CONCLUSIONS

Health is not a motivating factor for adolescents; therefore, interventions designed solely to improve health are unlikely to engage them. Instead, interventions that align with the values and priorities specified by adolescents are more likely to be effective in supporting them to eat well and be more active.

Behavioral Weight Loss Intervention Preferences of Adolescents with Overweight/Obesity

Background: Behavioral lifestyle interventions are the foundation of adolescent obesity treatment. Tailoring an intervention using adolescent stakeholder engagement during the development process could improve intervention effectiveness. Methods: Adolescents with overweight/obesity ages 14-19 (n = 41) participated in 11 sex-specific focus groups (girls = 6, boys = 5) and were asked their preferences regarding who should lead the intervention and be involved, what the messaging of the program should be, how to make the program engaging and maintain participation, and how to best measure nutrition intake and activity. Transcripts were coded and analyzed for emergent themes. Results: Mean age was 16.0 ± 1.8 years and participants were racially/ethnically diverse. Adolescents preferred interventions that avoid a focus on "weight loss," and instead emphasize "healthy lifestyle," which represents a more comprehensive goal of targeting physical and mental well-being. Most participants indicated preferences for a relatable instructor with prior weight loss experience. Both sexes preferred optional parental involvement, as some parents were described as helpful, while others were perceived as a hindrance to success. Boys and girls identified incentives, engaging activities, and electronic communication as core components for engagement and retention, with girls emphasizing socialization and building relationships. Sex differences in preferences were observed. Girls had more concerns about intervention participation and preferred interventions to be sex stratified. Conclusions: Behavioral interventions to treat adolescent obesity should focus messaging/content on healthy lifestyles, rather than weight loss, and be sex stratified. Development and implementation of future behavioral interventions for adolescent obesity should consider tailoring to adolescent preferences when possible to improve feasibility, acceptability, and effectiveness.

Parental perspectives on negotiations over diet and physical activity: how do we involve parents in adolescent health interventions?

OBJECTIVE

To identify the ways in which parental involvement can be incorporated into interventions to support adolescent health behaviour change.

DESIGN

Data from semi-structured interviews were analysed using inductive thematic analysis.

SETTING

Southampton, Hampshire, UK.

PARTICIPANTS

A convenience sample of twenty-four parents of adolescents.

RESULTS

Parents consider themselves to play an important role in supporting their adolescents to make healthy choices. Parents saw themselves as gatekeepers of the household and as role models to their adolescents but recognised this could be both positive and negative in terms of health behaviours. Parents described the changing dynamics of the relationships they have with their adolescents because of increased adolescent autonomy. Parents stated that these changes altered their level of influence over adolescents' health behaviours. Parents considered it important to promote independence in their adolescents; however, many described this as challenging because they believed their adolescents were likely to make unhealthy decisions if not given guidance. Parents reported difficulty in supporting adolescents in a way that was not viewed as forceful or pressuring.

CONCLUSIONS

When designing adolescent health interventions that include parental components, researchers need to be aware of the disconnect between public health recommendations and the everyday reality for adolescents and their parents. Parental involvement in adolescent interventions could be helpful but needs to be done in a manner that is acceptable to both adolescents and parents. The findings of this study may be useful to inform interventions which need to consider the transitions and negotiations which are common in homes containing adolescents.

Ranking of meal preferences and interactions with demographic characteristics: a discrete choice experiment in young adults

BACKGROUND

The diet of young adults is poor, yet little is known about the relative importance of influences on healthy eating in a decision-making context. The aim of this exploratory study was to understand the relative ranking of influences on meal choices in young adults and to investigate interactions between meal preferences and demographic and health characteristics.

METHODS

Adults aged 18-30 years (n = 92, mean age: 23.9 (SD 3.4) years) completed an online discrete choice experiment. Participants were presented with 12 choice sets reflecting a typical weekday meal and were asked to choose between four meal options. Each meal consisted of a combination of five meal attributes (preparation time, cost, taste, familiarity and nutrition content) that each had three attribute levels. Data were analysed using conditional logit models. Subgroup analyses were performed by sex, education, income, weight status and meeting fruit and vegetable recommendations.

RESULTS

Comparing the highest and lowest attribute levels, meal preferences were higher for better taste (B = 0.38; 95% CI: 0.12, 0.63), familiarity (B = 0.37; 95% CI: 0.21, 0.54) and nutrition content (B = 1.11; 95% CI: 0.81, 1.41) and lower for increased preparation times (B = -0.33; 95% CI: - 0.53, - 0.12) and cost (B = -0.50; 95% CI: - 0.75, - 0.24). Nutrition content was the most important influence on meal choice. Cost was the second most important, followed by taste, familiarity and preparation time. Compared to males, females had a higher preference for better nutrition content, taste and familiarity and a lower preference for increased cost. Higher educated participants had a higher preference for better nutrition content, familiarity and taste compared to lower educated participants. Young adults who met recommendations for fruit and vegetable intake had a higher preference for better nutrition content compared to participants who did not meet recommendations.

CONCLUSION

Nutrition content was the most important influence on young adults' meal choices, followed by cost, taste, familiarity and preparation time. Preferences varied by demographics and health characteristics, suggesting that the focus of dietary interventions may benefit from being tailored to specific young adult groups.

Can counter-advertising protect spectators of elite sport against the influence of unhealthy food and beverage sponsorship? A naturalistic trial

RATIONALE AND OBJECTIVE

Unhealthy, energy-dense nutrient-poor foods and beverages are heavily promoted through sport sponsorship. This naturalistic trial assessed whether exposing young adult spectators to various types of counter-advertising (CA) before watching an unhealthy food sponsored elite sporting event could diminish sponsorship effects and increase support for restrictions on sponsorship.

METHOD

Young adults (ages 18-29 years) who planned to watch the Australian Football League (AFL) Grand Final were recruited through an online panel and randomly assigned to one of four conditions: (A) control (neutral advertisement); (B) anti-industry CA (critiquing unhealthy food industry sponsorship of sport); (C) anti-product CA (critiquing the association of sports stars with unhealthy food); or (D) negative health effects CA (highlighting negative health consequences of unhealthy food consumption). Participants (N = 1316) completed a pre-test questionnaire and viewed their assigned CA online 1-3 days before watching the 2017 AFL Grand Final, which featured unhealthy food sponsorship.

RESULTS

Participants who reported watching the AFL Grand Final (n = 802) answered post-test measures within five days of the event. Results indicated that participants found the anti-industry CA more believable, attention-grabbing, reassuring and encouraging than the anti-product CA. The anti-industry CA promoted less favourable attitudes to sponsor brands, the anti-product CA promoted reduced intentions to purchase the fast-food sponsor brand, and the negative health effects CA reduced preferences for fast food in general compared to the control condition.

CONCLUSIONS

Anti-industry CA may detract from favourable attitudes to unhealthy food sponsor brands and negative health effects CA may detract from intentions to consume fast food in the face of unhealthy food sponsorship exposure. Such interventions may require higher dosage levels than applied in the present study to bolster spectators' resistance to the surfeit of unhealthy food sport sponsorship.

Engaging adolescents in changing behaviour (EACH-B): a study protocol for a cluster randomised controlled trial to improve dietary quality and physical activity

BACKGROUND

Poor diet and lack of physical activity are strongly linked to non-communicable disease risk, but modifying them is challenging. There is increasing recognition that adolescence is an important time to intervene; habits formed during this period tend to last, and physical and psychological changes during adolescence make it an important time to help individuals form healthier habits. Improving adolescents' health behaviours is important not only for their own health now and in adulthood, but also for the health of any future children. Building on LifeLab-an existing, purpose-built educational facility at the University of Southampton-we have developed a multi-component intervention for secondary school students called Engaging Adolescents in Changing Behaviour (EACH-B) that aims to motivate and support adolescents to eat better and be more physically active.

METHODS

A cluster randomised controlled trial is being conducted to evaluate the effectiveness of the EACH-B intervention. The primary outcomes of the intervention are self-reported dietary quality and objectively measured physical activity (PA) levels, both assessed at baseline and at 12-month follow-up. The EACH-B intervention consists of three linked elements: professional development for teachers including training in communication skills to support health behaviour change; the LifeLab educational module comprising in-school teaching of nine science lessons linked to the English National Curriculum and a practical day visit to the LifeLab facility; and a personalised digital intervention that involves social support and game features that promote eating better and being more active. Both the taught module and the LifeLab day are designed with a focus on the science behind the messages about positive health behaviours, such as diet and PA, for the adolescents now, in adulthood and their future offspring, with the aim of promoting personal plans for change. The EACH-B research trial aims to recruit approximately 2300 secondary school students aged 12-13 years from 50 schools (the clusters) from Hampshire and neighbouring counties. Participating schools will be randomised to either the control or intervention arm. The intervention will be run during two academic years, with continual recruitment of schools throughout the school year until the sample size is reached. The schools allocated to the control arm will receive normal schooling but will be offered the intervention after data collection for the trial is complete. An economic model will be developed to assess the cost-effectiveness of the EACH-B intervention compared with usual schooling.

DISCUSSION

Adolescents' health needs are often ignored and they can be difficult to engage in behaviour change. Building a cheap, sustainable way of engaging them in making healthier choices will benefit their long-term health and that of their future children.

TRIAL REGISTRATION

ISRCTN 74109264 . Registered on 30 August 2019. EACH-B is a cluster randomised controlled trial, funded by the National Institute for Health Research (RP-PG-0216-20004).

Evaluating values-based message frames for type 2 diabetes prevention among Facebook audiences: Divergent values or common ground?

OBJECTIVE

To effectively confront the type 2 diabetes (T2D) epidemic, policymakers and the public need to problematize T2D less as a medical and more as a social problem. An award-winning T2D prevention campaign was harnessed to determine the most successful ways of framing ads on Facebook.

HYPOTHESIS

We will observe variation in the effectiveness of ad message-frames within audience-segments.

METHODS

Six parallel quasi-experiments (participants N = 203,156) were conducted with 6 disparate audience-segments defined through the Facebook ads-manager tool. Across all audiences, we exposed Facebook users to values-based ad-frames (10-15-word appeals), assigning 7 of 11 possible frames to participants within each audience in a quasi-experimental fashion (using Facebook users' birth-month). Engagement was measured by rates of ad video-views, unique-link-clicks and donations to the campaign.

RESULTS

Contrary to our hypothesis, we observed remarkable consistency across target audiences. Ad-frames that ranked highly with most audience-segments included Entertainment and Emotional Appeal; Defiance Against Authority Appeal; Second-Hand Smoke/Environmental Appeal; and to a lesser extent, Common-Enemy/War-Metaphor Appeal. Conclusion and Practice-Implications: Across disparate segments of society, there appears to be a set of common values that public health communication initiatives can tap into to catalyze a more inclusive movement to confront the T2D epidemic through policy, systems and environmental approaches.

Behaviour change interventions: getting in touch with individual differences, values and emotions

Systematic reviews and meta-analyses suggest that behaviour change interventions have modest effect sizes, struggle to demonstrate effect in the long term and that there is high heterogeneity between studies. Such interventions take huge effort to design and run for relatively small returns in terms of changes to behaviour.So why do behaviour change interventions not work and how can we make them more effective? This article offers some ideas about what may underpin the failure of behaviour change interventions. We propose three main reasons that may explain why our current methods of conducting behaviour change interventions struggle to achieve the changes we expect: 1) our current model for testing the efficacy or effectiveness of interventions tends to a mean effect size. This ignores individual differences in response to interventions; 2) our interventions tend to assume that everyone values health in the way we do as health professionals; and 3) the great majority of our interventions focus on addressing cognitions as mechanisms of change. We appeal to people's logic and rationality rather than recognising that much of what we do and how we behave, including our health behaviours, is governed as much by how we feel and how engaged we are emotionally as it is with what we plan and intend to do.Drawing on our team's experience of developing multiple interventions to promote and support health behaviour change with a variety of populations in different global contexts, this article explores strategies with potential to address these issues.

Potential Preventive Strategies for Amyotrophic Lateral Sclerosis

It may seem useless to propose preventive measures for a disease without established pathogenesis and successful therapy, such as amyotrophic lateral sclerosis (ALS). However, we will show that ALS shares essential molecular mechanisms with aging and that established anti-aging strategies, such as healthy diet or individually adjusted exercise, may be successfully applied to ameliorate the condition of ALS patients. These strategies might be applied for prevention if persons at ALS risk could be identified early enough. Recent research advances indicate that this may happen soon.

The Paradoxical Consequences of Choice: Often Good for the Individual, Perhaps Less So for Society?

The proliferation of products and services, together with the rise of social media, affords people the opportunity to make more choices than ever before. However, the requirement to think in terms of choice, or to use a choice mind-set, may have powerful but unexamined consequences for judgment and decision making, both for the chooser and for others. A choice mind-set leads people to engage in cognitive processes of discrimination and separation, to emphasize personal freedom and independent agency, and to focus on themselves rather than others. Reviewing research from social psychology, legal studies, health and nutrition, and consumer behavior, we found evidence that although a choice mind-set may have positive consequences for the individual, the accumulated outcome of thinking in terms of individual choice may have detrimental outcomes for society. Given the prevalence of choice in all domains of life, more research examining the full range of the consequences of choice is urgently needed.

Sports Sponsorship as a Cause of Obesity

PURPOSE OF REVIEW

This article investigates the role of food and beverage sponsorship of sports in influencing dietary behaviour, and ultimately obesity, focusing on research published in the past 5 years. A systematic strategy was used to search the health science, social science and marketing databases to identify peer-reviewed literature on food and non-alcoholic beverage company sponsorship of sport published in English from 2015 to 2019.

RECENT FINDINGS

Sixteen discrete studies were identified: six content analyses, two qualitative studies, four cross-sectional surveys and four experimental studies. Findings indicate sports sponsorship is widely used to promote unhealthy foods through professional and community sport, prompting increased awareness and preference for sponsor products. Most studies assessed self-reported responses to sponsorship, with a lack of behavioural data on food purchasing and consumption. Sports sponsorship by unhealthy food brands achieves vast population reach and exposure, promoting increased brand awareness and preference for sponsor products. Research is needed to improve our understanding of the relationship between food and beverage sponsorship and energy intake. Research evaluating the efficacy of strategies to reduce spectator's exposure to unhealthy sports sponsorship is also needed.
