An analysis of food and beverage advertising on bus shelters in a deprived area of Northern England

Objective: To quantify the extent of food and beverage advertising on bus shelters in a deprived area of the UK, to identify the healthfulness of advertised products, and any differences by level of deprivation. The study also sought to assess the creative strategies used and extent of appeal to young people. Design: Images of bus shelter advertisements were collected via in person photography (in 2019) and Google Street View (photos recorded in 2018). Food and beverage advertisements were grouped into one of seventeen food categories and classified as healthy/less healthy using the UK Nutrient Profile Model. The deprivation level of the advertisement location was identified using the UK Index of Multiple Deprivation. Setting: Middlesbrough and Redcar and Cleveland in South Teesside. Participants: N/A Results: 832 advertisements were identified, almost half (48.9%) of which were for foods or beverages. Of food and non-alcoholic beverage adverts, 35.1% were less healthy. Most food advertisements (98.9%) used at least one of the persuasive creative strategies. Food advertisements were found to be of appeal to children under 18 years (71.9%). No differences in healthiness of advertised foods were found by level of deprivation. Conclusions: Food advertising is extensive on bus shelters in parts of the UK, and a substantial proportion of this advertising is classified as less healthy and would not be permitted to be advertised around television programming for children. Bus shelter advertising should be considered part of the UK policy deliberations around restricting less healthy food marketing exposure.

Food Marketing to Children in Iran: Regulation that Needs Further Regulation

Increased exposure to advertising of unhealthy food products is one of the main risk factors for the increased prevalence of childhood obesity and non-communicable diseases. This scoping review aimed to investigate the characteristics and effects of food advertisements targeted at children in Iran and review the existing regulations on food marketing targeted at children in the country. In this study, we searched Web of Science, Scopus, PubMed, Google, and Google scholar, in addition to Iranian scientific search engines, including Iranian Research Institute for Information Science and Technology (Iran.doc), Scientific Information Database (SID), Iranmedex, Magiran, and Civilica up to December 2020 to find any literature about food marketing to children in Iran and current related regulations and policies in the country. A total of 23 eligible studies were selected for this review. Most of the studies had focused on television as the media to assess. The main food products advertised with reference to children included: Salty snacks, including cheese puffs, chips, cheese fish snacks, puffed corn, and sweet snacks such as ice creams, cakes/biscuits/cookies and candies, beverages/drinks/soft drinks/fruit juices, dried fruits and fruit rolls, and chocolates. Strategies that most commonly used in marketing foods to children in Iran were emotional appeals, misleading messages/claims, use of music and known characters to children, as well as conveying happiness and/or security. The main reported violation of food regulations included using obese children, either as consumers or presenters of the product. In Iran the advertising of unhealthy food products for the general population is banned; however, it is weakly implemented. There are a limited number of regulations that have addressed children explicitly in this regard. The main barriers identified in partial implementation of regulations included weakness in scientific criteria, legal enforcement guarantee, poor intersectoral collaboration, inadequate infrastructures, and poor monitoring. Policies and regulations in food marketing need to clearly address children as an important audience. It is suggested future policies focused on children cover all forms of food marketing and consider all types of persuasive food marketing strategies targeted at children.

Impact of a voluntary industry code for advertising food to children and young people: an analysis of New Zealand television data

Objective: To evaluate the impact of the 2017 update to the voluntary Advertising Standards Authority (ASA) Code for Advertising Food on children and young people’s exposure to unhealthy food advertisements on New Zealand television. Design: Audience ratings data were analysed for New Zealand children and young people’s television viewing for eight random days prior to (June to August 2015) and following (October to December 2018) the code update, from 6.00am-midnight (864 hours). Food advertisements were coded using three nutrient profiling models. The number of children and young people watching television each year were compared. Setting: Three free-to-air New Zealand television channels. Participants: New Zealand children aged 5-18 years. Results: Television viewer numbers decreased over the three years (P<0.0001). The mean rate of unhealthy food advertising on weekdays was 10.4 advertisements/hour (2015) and 9.5 advertisements/hour (2018). Corresponding rates for weekend days were 8.1 and 7.3 advertisements/hour, respectively. The percentage of food advertisements which were for unhealthy foods remained high (63.7% on weekdays and 65.9% on weekends) in 2018. The ASA definition of children’s ‘peak viewing time’ (when 25% of the audience are children) did not correspond to any broadcast times across weekdays and weekend days. Conclusions: Between 2015 and 2018, children and young people’s television exposure to unhealthy food advertising decreased. However, almost two-thirds of all food advertisements were still unhealthy, and the updated ASA code excluded the times when the greatest number of children were watching television. Consequently, government regulation and regular monitoring should reflect the evolving food marketing environment.

Exposure of French Children and Adolescents to Advertising for Foods High in Fat, Sugar or Salt

Food marketing of products high in fat, sugar and salt (HFSS), including television advertising, is one of the environmental factors considered as a contributor to the obesity epidemic. The main objective of this study was to quantify the exposure of French children and adolescents to television advertisements for HFSS products. TV food advertisements broadcast in 2018 were categorized according to the Nutri-Score of the advertised products. These advertisements, identified according to the days and times of broadcast, were cross-referenced with audience data for 4- to 12-year-olds and 13- to 17-year-olds. More than 50% of food advertisements seen on television by children and adolescents concerned HFSS products, identified as classified as Nutri-Score D and E. In addition, half of advertisements for D and E Nutri-Score products were seen by children and adolescents in the evening during peak viewing hours, when more than 20% of both age groups watched television. On the other hand, during the same viewing hours, the percentage of children and adolescents who watched youth programs, the only programs subject to an advertising ban, was very low (<2%). These results show that the relevance of regulating advertising at times when the television audience of children and adolescents is the highest and not targeted at youth programs, in order to reduce their exposure to advertising for products of low nutritional quality.

How Food Marketing on Instagram Shapes Adolescents’ Food Preferences: Online Randomized Trial

Background Worldwide obesity rates have prompted 16 countries to enact policies to reduce children’s exposure to unhealthy food marketing, but few policies address online advertising practices or protect adolescents from being targeted. Given adolescents spend so much time online, it is critical to understand how persuasive Instagram food advertisements (ads) are compared with traditional food ads. To strengthen online food marketing policies, more evidence is needed on whether social media ads are more persuasive than other types of ads in shaping adolescents’ preferences. Objective This study examined whether adolescents could identify food companies’ Instagram posts as ads, and the extent to which Instagram versus traditional food ads shape adolescents’ preferences. Methods In Part 1, participants aged 13-17 years (N=832) viewed 8 pairs of ads and were asked to identify which ads originated from Instagram. One ad in each pair was selected from traditional sources (eg, print; online banner ad), and the other ad was selected from Instagram, but we removed the Instagram frame—which includes the logo, comments, and “likes.” In Part 2, participants were randomized to rate food ads that ostensibly originated from (1) Instagram (ie, we photoshopped the Instagram frame onto ads); or (2) traditional sources. Unbeknownst to participants, half of the ads in their condition originated from Instagram and half originated from traditional sources. Results In Part 1, adolescents performed worse than chance when asked to identify Instagram ads (P<.001). In Part 2, there were no differences on 4 of 5 outcomes in the “labeled ad condition.” In the “unlabeled ad condition,” however, they preferred Instagram ads to traditional ads on 3 of 5 outcomes (ie, trendiness, P=.001; artistic appeal, P=.001; likeability, P=.001). Conclusions Adolescents incorrectly identified traditional ads as Instagram posts, suggesting the artistic appearance of social media ads may not be perceived as marketing. Further, the mere presence of Instagram features caused adolescents to rate food ads more positively than ads without Instagram features.

Exposure to unhealthy food and beverage advertising during the school commute in Australia

BackgroundFood marketing exposure has the potential to influence children’s dietary behaviours and health status, however, few studies have identified how ‘obesogenic’ the outdoor food marketing environment is along public transport (bus and/or train) or walking routes that children take to school.MethodsAudits of all outdoor advertisements present along likely train, bus and walking routes to 24 secondary schools (ie, 3 routes per school, 72 routes total) were conducted in Perth, Western Australia (WA). The size, content, type and setting of each advertisement were recorded in accordance with the International Network for Food and Obesity/non-communicable diseases Research, Monitoring and Action Support protocol for monitoring outdoor advertising.ResultsOf the 4016 total advertisements observed, almost half were for food (n=1754, 44%) and of these, 80% (n=1397) advertised discretionary (non-core) foods, and 8% (n=138) advertised healthy (core) foods. On average, commuting to school by train, bus and walking exposed Perth schoolchildren to 37.1, 22 and 4.5 discretionary (non-core) food ads per one-way trip to school, respectively.ConclusionsChildren living in Perth, WA experience a high level of exposure to unhealthy outdoor food advertisements during the school commute. Policies which restrict the placement and content of outdoor advertising, could be a useful strategy in the fight against childhood obesity.

Children’s measured exposure to food and beverage advertising on television in Toronto (Canada), May 2011–May 2019

Objective Exposure to unhealthy food advertising is a known determinant of children’s poor dietary behaviours. The purpose of this study was to quantify and characterize Canadian children’s exposure to food advertising on broadcast television and examine trends over time. Methods Objectively measured advertising exposure data for 19 food categories airing on 30 stations broadcast in Toronto were licenced for May 2011 and May 2019. Using ad ratings data, the average number of food advertisements viewed by children aged 2–11 years, overall, by food category and by type of television station (child-appealing, adolescent-appealing and generalist stations), was estimated per time period. Results In May 2019, children viewed an average of 136 food advertisements on television, 20% fewer than in May 2011. More than half of advertisements viewed in May 2019 promoted unhealthy food categories such as fast food (43% of exposure), candy (6%), chocolate (6%) and regular soft drinks (5%) and only 17% of their total exposure occurred on child-appealing stations. Between May 2011 and May 2019, children’s exposure increased the most, in absolute terms, for savory snack foods (+7.2 ad exposures/child), fast food (+5.4) and regular soft drinks (+5.3) with most of these increases occurring on generalist stations. Conclusion Canadian children are still exposed to advertisements promoting unhealthy food categories on television despite voluntary restrictions adopted by some food companies. Statutory restrictions should be adopted and designed such that children are effectively protected from unhealthy food advertising on both stations intended for general audiences and those appealing to younger audiences.
