Where are the alcohol advertising hotspots near schools?

ISSUE ADDRESSED: Physically locating liquor stores near schools can strongly influence the chances of youth accessing and consuming alcohol, and may also increase children's exposure to alcohol advertising. Investigating the association between the presence of a liquor store near a school and the prevalence of outdoor alcohol advertising is crucial from a policy perspective, as it can inform future regulations on the placement of liquor stores and outdoor advertising near educational institutions. METHODS: All outdoor alcohol advertising within a 500 m radius (audit zone) of 64 randomly selected schools from local government areas across metropolitan Perth was identified by direct observation; recording the size, setting, location and content of each advertisement. Results were compared based on whether the school audit zone contained a liquor store or not. RESULTS: Over half (n = 36, 56%) of all school audit zones had at least one alcohol advertisement, with an average number of 5.9 alcohol advertisements per zone (SD = 10.2). The majority (97.9%) of advertisements were in the 38 audit zones containing a liquor store (average = 9.7, SD = 11.9 per zone), compared to zones without a liquor store (average = .3, SD = .7 per zone). CONCLUSIONS: Perth school zones containing a liquor store in their 500 m radius had, on average, 30 times more outdoor alcohol advertising, compared with school zones without a nearby liquor store. SO WHAT?: The siting of liquor stores and the display of alcohol advertisements around educational settings require combined policy, planning and public health approaches to mitigate children's exposure to alcohol marketing, especially during school transit.

Effects of bitten food images in marketing communications.

Marketing communications (e.g., food packages, restaurant menus, coupons, social media posts) often include images of bitten and non-bitten (i.e., complete) foods. Taking an empirics first approach, the current research explores how and why these images influence consumers. A field study shows a higher redemption rate for discount coupons featuring a bitten (vs. non-bitten) food. However, a controlled online study fails to replicate this effect. Two additional preregistered studies shed light on the inconsistent results observed online and in the field by identifying two competing mechanisms catalyzed by bitten food images. Bitten food images lead to vicarious enticement, an automatic process in which a viewer makes sense of a bitten food image by picturing someone approaching and tasting the food, as well as emotional conflict (i.e., the simultaneous activation of positive and negative thoughts and feelings). While vicarious enticement has a positive impact on product responses, emotional conflict has a negative impact. The effect of bitten (vs. non-bitten) food images on product responses appears to depend on the strength of these two mechanisms in a given context. These findings yield insights for researchers examining visual characteristics of food images as well as advertisers designing marketing communications.

'Meat' the influencers: Crafting authentic endorsements that drive willingness to buy cultured meat.

Cultured meat is a promising substitute for regular meat, but its introduction faces challenges and expected consumer resistance. While some studies investigate how communication strategies and advertising appeals can address these concerns, the role of social media influencers in promoting cultured meat adoption remains yet to be explored. Across two online experimental studies involving 752 participants recruited from Prolific, this research investigates how influencer type (micro- vs. mega-influencer) affects consumers' willingness to buy cultured meat. Study 1 reveals that consumers are more willing to buy cultured meat when it is endorsed by micro- rather than mega-influencers. Further, perceived endorsement authenticity mediates this effect such that micro-influencers endorsements are perceived as more authentic than those of mega-influencers. Study 2 demonstrates that these effects are moderated by influencer expertise and type of meat, where micro-influencers with health (but not fashion) expertise have a more pronounced impact on increasing willingness to purchase cultured meat (but not regular meat). This research provides theoretical insights into how consumers perceive influencer endorsements for cultured meat. These findings aim to enhance consumer acceptance of cultured meat while offering actionable guidance for practitioners on promoting cultured meat brands on social media.

Comparison of ten policy options to equitably reduce children's exposure to unhealthy food marketing.

OBJECTIVE: Reducing children's exposure to unhealthy food marketing is crucial to combat childhood obesity. We aimed to estimate the reduction of children's exposure to food marketing under different policy scenarios and assess exposure differences by socio-economic status. DESIGN: Data on children's exposure to unhealthy food marketing were compiled from a previous cross-sectional study in which children (n 168) wore wearable cameras and Global Positioning System (GPS) units for 4 consecutive days. For each exposure, we identified the setting, the marketing medium and food/beverage product category. We analysed the percentage reduction in food marketing exposure for ten policy scenarios and by socio-economic deprivation: (1) no product packaging, (2) no merchandise marketing, (3) no sugary drink marketing, (4) no confectionary marketing in schools, (5) no sugary drink marketing in schools, (6) no marketing in public spaces, (7) no marketing within 400 m of schools, (8) no marketing within 400 m of recreation venues, (9) no marketing within 400 m of bus stops and (10) no marketing within 400 m of major roads. SETTING: Wellington region of New Zealand. PARTICIPANTS: 168 children aged 11-14 years. RESULTS: Exposure to food marketing varied by setting, marketing medium and product category. Among the ten policy scenarios, the largest reductions were for plain packaging (60·3 %), no sugary drink marketing (28·8 %) and no marketing in public spaces (22·2 %). There were no differences by socio-economic deprivation. CONCLUSIONS: The results suggest that plain packaging would result in the greatest decrease in children's exposure to food marketing. However, given that children are regularly exposed to unhealthy food marketing in multiple settings through a range of marketing mediums, comprehensive bans are needed to protect children's health.

Children's Perception of Food Marketing Across Digital Media Platforms.

Introduction: Exposure to food marketing increases the risk of poor diet. Children's perception and interpretation of food marketing across digital media platforms is understudied. Children aged 9-11 years are uniquely susceptible to food marketing because children may watch content alone, and it is unclear whether embedded ads are decipherable by children (e.g., social media influencers) and if children are receptive to advertisements. Methods: The authors collected data from 21 child-parent dyads in 2022 to fill this gap. Children were interviewed about their food marketing exposure and media use and were asked to share their perspectives on food advertisements. Parents completed a survey for household digital devices, demographics, and perception of their child's food advertising knowledge. Results: This study found that all children generally recognized direct food advertisements, could describe them with varying levels of confidence, and shared examples. Despite self-identifying ads and understanding the intent of advertising, many children are still receptive to advertisements on the basis of engaging content (e.g., liking the ads as entertainment, watching ads even when given the chance to skip the ad) and the food items marketed (e.g., liking the taste of foods). Conclusions: These findings suggest that knowledge of advertisement exposure and intent of advertising are not sufficient to reduce receptiveness of unhealthy food ad exposure. Additional research on the potential impacts of embedded ads, such as through social media influencers, is needed to understand children's interaction with the current digital media landscape.

Differences in children's exposure to television advertising of unhealthy foods and beverages in Spain by socio-economic level.

BACKGROUND: The influence of food advertising on food preferences and consumption could also contribute to the socio-economic inequalities among Spanish children in terms of eating habits and childhood obesity. Although the main food advertising channel targeted at children in Spain is television, available studies estimate exposure indirectly by combining content data with audience data. The aim of this study was therefore to describe the frequency of exposure to television advertising of unhealthy foods and drinks, measured directly, among Spanish children and adolescents, and analyse its socio-economic inequalities. METHODS: Observational study of television advertising impacts in a sample of 1590 children aged 4 to 16 years drawn from a consumer panel representative of the Spanish population in this age group, over the course of a full week of broadcasting in February 2022. The sample was obtained through stratified random sampling by Autonomous Region, with quotas being set by reference to socio-demographic variables. Exposure was measured with an audiometer, and the nutrient content of the food and drink advertised was analysed using the nutrient profile of the WHO Regional Office for Europe. We used the Chi-squared test to analyse possible differences in advertising coverage by socio-economic level. RESULTS: The participants saw a weekly mean of 82.4 food and drink commercials, 67.4 of which were for unhealthy products (81.8%), mostly outside the child-protection time slot. On average, low-social class participants received 94.4% more impacts from unhealthy food and drink advertising than did high-class participants (99.9 vs. 51.4 respectively). The mean advertising coverage of unhealthy foods and drinks was 71.6% higher in low-class than in high-class participants (10.9% vs. 18.7%; p = 0.01). CONCLUSION: Spanish children and adolescents received an average of 10 impacts per day from television spots for unhealthy foods and drinks. The exposure of low-class children is double that of high-class children, a finding compatible with the high prevalence of childhood obesity in Spain and the related socio-economic inequalities. To protect Spanish minors from the harmful effects of food advertising and reduce the related social health inequalities would require the implementation of a 24:00 watershed for unhealthy food advertising on television.

Exposure and power of TV food advertising during the COVID-19 pandemic in Brazil: a content analysis.

BACKGROUND: With the COVID-19 pandemic and the restrictions imposed to contain the spread of SARS-CoV-2, the Brazilian population has increased the time spent at home and watching television (TV). Since food advertising exposure is a key driver of food choices, this study described the content of food advertisements (ads) on Brazilian TV during the COVID-19 pandemic. METHODS: This is an exploratory study. A total of 684 h of TV programming comprised of three free-to-air channels and two pay-per-view channels was recorded from 06 a.m. to 12 a.m. for eight non-consecutive days in June 2020. A content analysis of all the food-related ads was carried out. The data collection process followed INFORMAS Protocol for TV food advertising monitoring. RESULTS: The sample was composed of 7,083 ads, 752 (10.6%) of which were food-related and 487 (6.9%) were promoting ultra-processed foods. The content analysis indicated seven thematic categories, all of them with reference to the COVID-19 pandemic: brand and product differentials (79.8%); visual and sound effects (70.2%); thematic campaigns (56.0%); digitization (22.9%); convenience (16.5%); economic benefits (11.9%); and commensality and social interaction (6.1%). Ads content varied according to the day of the week, the time of the day, the length of the ad, and the channel type. CONCLUSIONS: The thematic of food advertising on Brazilian TV during the COVID-19 pandemic is aligned with the country's health crisis context and varied during the programming.

Associations between everyday exposure to food marketing and hunger and food craving in adults: An ecological momentary assessment study.

Food marketing in television and digital media negatively affects appetitive sensations and eating behaviour in children, but effects are less well understood for outdoor food advertising and adults. This research used Ecological Momentary Assessment (EMA) to explore associations between exposures to food advertising in various contexts (television, digital, outdoors) and adults' hunger and craving for highly advertised food categories. Over one week, participants provided ratings of cravings for types of food (fast food, soft drinks, snacks/confectionery, other) and hunger on a smartphone app up to six times per day when they saw a food advertisement (reactive assessment) and at random intervals (random assessment). Fifty-four participants (70.4 % female; 21.24 ± 3.84 years) provided 1223 assessments (24.7 % reactive, 75.3 % random). Data were analysed in R using multilevel multivariable linear regression models. Participants reported feeling hungrier (X2(1) = 5.85, p = .016, ΔAIC = 3.9) and having stronger cravings (X2(1) = 20.64, p < .001, ΔAIC = 318.6) after seeing food advertisements vs. random assessments. This was driven by greater hunger following television advertising exposure vs. random assessments (ß = 1.58, SE = 0.61, p = .010, 95 %CIs 0.38 to 2.78), food advertising via digital devices or outdoors was not associated with hunger. Participants experienced stronger craving after seeing a food advertisement on television (ß = 0.52, SE = 0.19, p = .006, 95 %CIs 0.15 to 0.89), outdoors (ß = 0.39, SE = 0.12, p < .001, 95 % CIs 0.16 to 0.62) and in digital media (ß = 0.36, SE = 0.14, p = .012, 95 % CIs 0.08 to 0.64), vs. random assessments. Cravings were (largely) specific to the advertised food category. EMA can be effective for assessing food marketing associations in adults. The current study provides evidence that food marketing is associated with hunger and craving in adults, which may, with replication, have implications for public health policy.

Revolutionising food advertising monitoring: a machine learning-based method for automated classification of food videos.

OBJECTIVE: Food advertising is an important determinant of unhealthy eating. However, analysing a large number of advertisements (ads) to distinguish between food and non-food content is a challenging task. This study aims to develop a machine learning-based method to automatically identify and classify food and non-food ad videos. DESIGN: Methodological study to develop an algorithm model that prioritises both accuracy and efficiency in monitoring and classifying advertising videos. SETTING: From a collection of Brazilian television (TV) ads data, we created a database and split it into three sub-databases (i.e. training, validation and test) by extracting frames from ads. Subsequently, the training database was classified using the EfficientNet neural network. The best models and data-balancing strategies were investigated using the validation database. Finally, the test database was used to apply the best model and strategy, and results were verified with field experts. PARTICIPANTS: The study used 2124 recorded Brazilian TV programming hours from 2018 to 2020. It included 703 food ads and over 20 000 non-food ads, following the protocol developed by the INFORMAS network for monitoring food marketing on TV. RESULTS: The results showed that the EfficientNet neural network associated with the balanced batches strategy achieved an overall accuracy of 90·5 % on the test database, which represents a reduction of 99·9 % of the time spent on identifying and classifying ads. CONCLUSIONS: The method studied represents a promising approach for differentiating food and non-food-related video within monitoring food marketing, which has significant practical implications for researchers, public health policymakers, and regulatory bodies.

Monitoring Food Marketing Directed to Portuguese Children Broadcasted on Television.

Children are massively exposed to food marketing through television and other forms of media. Marketing strategies promote unhealthy eating behaviours and contribute to childhood obesity. The main aim of this study was to assess the potential exposure and power of food advertisements aimed at children, broadcasted on Portuguese television. Television data was recorded for two weekdays and two weekend days between 6 am and 10 pm during November 2021 from four free-access Portuguese television channels. Data was analysed according to the World Health Organization television protocol and Portuguese Legislation. We identified 5272 advertisements, of which 11.2% were for food and beverages (n = 590). Most advertised food categories for children and adolescents were chocolate and bakery products (42.0%), soft drinks (26.7%), and yoghurt (16.0%), and none met the nutritional profile outlined by the national legislation. Unhealthier food advertisements targeting youth were shown in children's non-peak time and morning during news and entertainment programmes. Product uniqueness, humour, and fun were the most frequent primary persuasive techniques. Most advertisements showed a high use of brand logos, product images, and premium offers. In conclusion, Portuguese children and adolescents are potentially exposed to large numbers of unhealthy food advertisements on television, despite marketing regulation and restriction policies.
