RESUMO

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.

RESUMO

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.

RESUMO

Popular social media platforms have been actively used by ultra-processed food companies to promote their products. Being exposed to this type of advertising increases the consumption of unhealthy foods and the risk of developing obesity and other non-communicable diseases (NCDs). Thus, monitoring commercial content on social media is a core public health practice. We aimed to characterize the methods used for monitoring food advertising on social media and summarize the investigated advertising strategies via a scoping review of observational studies. This study is reported according to the MOOSE Statement, and its protocol was registered with the PROSPERO International Prospective Register of Systematic Reviews (registration nº. CRD42020187740). Out of the 6093 citations retrieved, 26 met our eligibility criteria. The studies were published from 2014 to 2021, mostly after 2018. They focused on Australia, Facebook, strategies aimed at children and adolescents, and advertising practices of ultra-processed food companies. We grouped strategies in eight classes: post features (n = 18); connectivity and engagement (n = 18); economic advantages, gifts, or competitions (n = 14); claims (n = 14); promotional characters (n = 12); brand in evidence (n = 8); corporate social responsibility or philanthropy (n = 7); and COVID-19 (n = 3). We found similarities in the investigation of strategies regardless of the type of social media. Our findings can contribute to the designing of tools for monitoring studies and regulatory mechanisms to restrict the exposure of food advertising.

RESUMO

The Big Soda segment is central in modern food systems, and they invest heavily in digital marketing, but little is known about it. We aimed to analyze the digital marketing on Facebook of the soda brand with a major worldwide reach. Countries were described in terms of soda brand presence and popularity on Facebook according to countries' socio-demographic index (SDI) and the market share of soda brand (%MS). From 149 countries, 57.0% had soda brand's Facebook page among the top five in the number of followers within the beverage segment. Among them, digital marketing was described by the number of the page followers, the number of posts, and the number of interactions (likes, comments and shares) that each post received by Facebook users. Also, we analyzed the characteristics, and the use of marketing strategies on posts in a random sample of 10% (n = 1217) of all posts. We found that soda brand's popularity on Facebook was higher among countries with higher SDI and higher %MS. Also, the number of users that engaged with soda brand's posts was higher among countries with lower SDI and higher brand's %MS. The brand's posts focus on young adults, display of brand's products and glorification of its attributes. Other identified features include sport-related thematic and appeals to socialization and healthy eating. In addition, posts' characteristics differed with countries' characteristics. Soda brand digital marketing varies according to countries' characterization and maintains the brand position on the global marketing of beverages.


The concentration of power of transnationals food and beverage corporations across the entire food system chain has contributed to unfavorable outcomes in the health and diets of the population. The reasons may be due to the low-nutritional value of the foods and beverages produced by these transnationals and the wide promotion of these products through marketing strategies. These two points are important stages of modern food systems. The marketing practices of these companies influence the food choices of individuals. They are attracted by the high level of persuasion employed through different strategies, especially in the digital environment. Strategies in the digital environment are widely available and accessed by individuals in every country in the world. For this reason, we focus on understanding the digital marketing of an important soda brand with a major worldwide reach to understand its particulars. We show that this top big soda brand uses digital marketing to promote its products globally and presenting particularities aligned with the socio-demographic conditions of the countries and regarding its market share. These results show that monitoring the behavior, especially on digital media, of large food and beverage companies is essential to advance policies that regulate market practices to protect individuals from their externalities in the field of global public health.

RESUMO

OBJECTIVE: To investigate the advertising patterns on the posts of a fast-food chain in Brazil on three social media platforms in 2019. DESIGN: An exploratory cross-sectional study. SETTING: Advertising strategies on the posts of a major fast-food chain on their official Facebook, Instagram and YouTube accounts. The strategies were investigated according to the INFORMAS protocol for food promotion monitoring. Principal component analysis (PCA) was employed to identify advertising patterns in each platform. PARTICIPANTS: 305 advertisements. RESULTS: Four advertising patterns were identified in the PCA of Facebook and Instagram. In both platforms, the components for kids and product exaltation were similar. On Facebook, a pattern corresponding to economic appeal was identified as price and discount, while on Instagram, this pattern also included a practical approach. On Facebook, the fourth component was named celebrity, while on Instagram it was celebrity/innovation since on this second social media the component also included the 'new brand development' variable. On YouTube, three advertising patterns were identified in PCA. Similar to the other platforms, the first and the second patterns were called for kids and price and discount, and the third component referred to both celebrity and commemorative dates. CONCLUSIONS: The advertising patterns of the fast-food chain on three social media platforms were commonly directed to children and addressed price, discounts and the celebrities' universe. The findings of this study corroborate other data in the literature regarding unhealthy food advertising on social media. This study discusses the urgency of regulating food advertising content on this medium.

RESUMO

We analyzed the use of persuasive advertising strategies by 18 food brands on TV and Facebook, Instagram, and YouTube in Brazil in April 2018. Advertising strategies were investigated from three groups: power of advertising strategies (n = 10) (e.g., use of licensed character, celebrities, awards, etc), use of the prize offering (n = 9) (e.g., pay 2 take 3 or more, gifts or collectable, limited edition, etc), and use of brand benefit claims (n = 8) (e.g., messages that exalt sensory-based characteristics such as flavor, taste, aroma and recommend how to use/consume the product, etc). Almost 90% of the brands were ultra-processed foods producers and they carried 52 ads on TV and 194 posts on social media platforms. A higher frequency of the strategy 'cartoon/company owned character' was found on TV ads (19.2%; p < 0.0001) in comparison to social media platforms (0% on the three platforms) while the presence of 'famous sportsperson/team' prevailed on YouTube (41.4%) in comparison to TV (19.2%), Facebook (10.9%) and Instagram (9.1%), p < 0.0001. On YouTube ads, the claims 'sensory-based characteristics' (86.2%), 'suggested use' (51.7%), and 'emotive claims' (31.0%) were more commonly seen in comparison to the other media, while the claims about 'new brand developments' (23.1%), 'price' (9.6%) and 'suggesting to children and the whole family to use the advertised product' (21.1%) prevailed on TV. Ultra-processed food brands are the main food companies that advertise on Brazilian TV and social media and the message transmitted by these brands varies in each media according to the advertising strategies that are used.

RESUMO

The food information environment includes food advertising disseminated in various media. With the COVID-19 pandemic and the shutdown of schools, universities, non-essential commerce, public leisure areas, bars, restaurants, among others, the food information environment has changed in Brazil. People spent more time at home which led to greater exposure to television and internet advertising content. During the COVID-19 pandemic, the food production sector has invested in new ways to advertise their products that include advertising messages of support, empathy and solidarity, as well as social responsibility campaigns looking for self-promotion such as food donation and financial aids. Sponsoring online events promoted by Brazilian musicians on social media was also enhanced during the pandemic and allowed food companies to become part of the consumer's leisure and entertainment moments. The advertising strategies adopted by the food industry during the COVID-19 pandemic are used to generate market demands, influence the consumer purchase decision and increase their loyalty to the supplier brands. Consequently, individuals may have been more vulnerable to excessive consumption of ultra-processed foods during this health crisis. This commentary aims to describe the changes in the food information environment during the COVID-19 pandemic in Brazil and propose a pathway to promote a healthier food information environment after this health crisis. Perspectives for promoting a healthier food information environment after the pandemic are also discussed, focusing on regulating food advertising with a shared responsibility between government, the food industry, the academy and civil society.
