Food Marketing Influences Children's Attitudes, Preferences and Consumption: A Systematic Critical Review

Nutritional Analysis of Foods and Beverages Depicted in Top-Grossing US Movies, 1994-2018

IMPORTANCE

Many countries now restrict advertisements for unhealthy foods. However, movies depict foods and beverages with nutritional quality that is unknown, unregulated, and underappreciated as a source of dietary influence.

OBJECTIVE

To compare nutritional content depicted in top-grossing US movies with established nutrition rating systems, dietary recommendations, and US individuals' actual consumption.

DESIGN AND SETTING

In this qualitative study, a content analysis was performed from April 2019 to May 2020 of the 250 top-grossing US movies released from 1994 to 2018.

MAIN OUTCOMES AND MEASURES

The proportion of movies with less healthy nutrition ratings using the Nutrient Profile Index, the proportion of movies with medium or high food nutrition ratings according to the United Kingdom's "traffic light" guidelines (in which green is low and indicates the healthiest foods; amber, medium; and red is high and indicates the least healthy foods), and how the movie-depicted nutritional content compared with US Food and Drug Administration-recommended daily levels and US individuals' actual consumption according to National Health and Nutrition Examination Survey 2015-2016 data. Secondary outcomes compared branded and nonbranded items and tested whether outcomes changed over time or for movies targeting youths.

RESULTS

Across 9198 foods and 5748 beverages, snacks and sweets (2173 [23.6%]) and alcoholic beverages (2303 [40.1%]) were most commonly depicted. Alcohol comprised 23 of 127 beverages (18.1%) in G-rated movies, 268 of 992 beverages (27.0%) in PG-rated movies, 1503 of 3592 beverages (41.8%) in PG-13-rated movies, and 509 of 1037 beverages (49.1%) in R-rated movies. Overall, 178 of 245 movies (72.7%) earned less healthy Nutrient Profile Index food ratings and 222 of 246 movies (90.2%) earned less healthy beverage ratings, which would be unhealthy enough to fail legal limits for advertising to youths in the United Kingdom. Among foods, most movies depicted medium or high (amber or red traffic light) levels of sugar (229 of 245 [93.5%]), saturated fat (208 of 245 [84.9%]), total fat (228 of 245 [93.1%]), and, to a lesser extent, sodium (123 of 245 [50.2%]). Only 1721 foods and beverages (11.5%) were visibly branded, but branded items received less healthy nutrition ratings than nonbranded items. Overall, movies failed recommended levels of saturated fat per 2000 kcal by 25.0% (95% CI, 20.6%-29.9%), sodium per 2000 kcal by 3.9% (95% CI, 0.2%-7.9%), and fiber per 2000 kcal by 45.1% (95% CI, 42.9%-47.0%). Movies also depicted 16.5% (95% CI, 12.3%-21.0%) higher total sugar content per 2000 kcal and 313% (95% CI, 298%-329%) higher alcohol content per 2000 kcal than US individuals consume. Neither food nor beverage nutrition scores improved over time or among movies targeting youths.

CONCLUSIONS AND RELEVANCE

This study suggests that popular US movies depict an unhealthy diet that fails national dietary recommendations, akin to US individuals' actual diets. Depicting unhealthy consumption in media is a sociocultural problem that extends beyond advertisements and branded product placements.

The Frequency and Context of Snacking among Children: An Objective Analysis Using Wearable Cameras

Snacking is a common eating behaviour, but there is little objective data about children’s snacking. We aimed to determine the frequency and context of children’s snacking (n = 158; mean age = 12.6 years) by ethnicity, gender, socioeconomic deprivation and body mass index (BMI) children. Participants wore wearable cameras that passively captured images of their surroundings every seven seconds. Images (n = 739,162) were coded for snacking episodes, defined as eating occasions in between main meals. Contextual factors analysed included: snacking location, food source, timing, social contact and screen use. Rates of total, discretionary (not recommended for consumption) and healthful (recommended for consumption) snacking were calculated using negative binomial regression. On average, children consumed 8.2 (95%CI 7.4, 9.1) snacks per day, of which 5.2 (95%CI 4.6, 5.9) were discretionary foods/beverages. Children consumed more discretionary snacks than healthful snacks in each setting and at all times, including 15.0× more discretionary snacks in public spaces and 2.4× more discretionary snacks in schools. Most snacks (68.9%) were sourced from home. Girls consumed more total, discretionary and healthful snacks than boys, and Māori and Pacific consumed fewer healthful snacks than New Zealand (NZ) Europeans. Results show that children snack frequently, and that most snacking involves discretionary food items. Our findings suggest targeting home buying behaviour and environmental changes to support healthy snacking choices.

Promoting Resilience to Food Commercials Decreases Susceptibility to Unhealthy Food Decision-Making

Children are vulnerable to adverse effects of food advertising. Food commercials are known to increase hedonic, taste-oriented, and unhealthy food decisions. The current study examined how promoting resilience to food commercials impacted susceptibility to unhealthy food decision-making in children. To promote resilience to food commercials, we utilized the food advertising literacy intervention intended to enhance cognitive skepticism and critical thinking, and decrease positive attitudes toward commercials. Thirty-six children aged 8–12 years were randomly assigned to the food advertising literacy intervention or the control condition. Eighteen children received four brief intervention sessions via video over 1 week period. In each session, children watched six food commercials with interspersed embedded intervention narratives. While watching food commercials and narratives, children were encouraged to speak their thoughts out loud spontaneously (“think-aloud”), which provided children's attitudes toward commercials. Eighteen children in the control condition had four control sessions over 1 week, and watched the same food commercials without intervention narratives while thinking aloud. The first and last sessions were held in the laboratory, and the second and third sessions were held at the children's homes. Susceptibility to unhealthy food decision-making was indicated by the decision weights of taste attributes, taste perception, food choices, ad libitum snacking, and cognitive and affective attitudes toward food commercials. As hypothesized, the intervention successfully decreased susceptibility to unhealthy food decision-making evidenced by reduced decision weights of the taste in food decisions, decreased tasty perception of unhealthy foods, and increased cognitive skepticism and critical thinking toward food commercials. In addition, as children's opinions assimilated to intervention narratives, their cognitive skepticism and critical thinking toward commercials increased. The aforementioned results were not shown in the control condition. However, this brief intervention was not enough to change actual food choices or food consumption. Results of this study suggest that promoting resilience to food commercials by enhancing cognitive skepticism and critical thinking effectively reduced children's susceptibility to unhealthy food-decision making.

The targeting of preschoolers, children, adolescents and adults by the Canadian food and beverage industry on television: a cross-sectional study

Unhealthy food advertising can negatively impact children's food preferences and nutritional health. In Canada, only companies participating in the self-regulatory Children's Food and Beverage Advertising Initiative (CAI) commit to limiting unhealthy food advertising to children. We analyzed food advertising from 182 Canadian television stations in 2018. A principal component analysis explored patterns of advertising by 497 food companies and their targeting of preschoolers, children, adolescents, and adults. Chi-square analyses tested differences in the volume of advertising between target age groups by heavily advertising food companies and by CAI-participating and non-participating companies. In 2018, Maple Leaf Foods, Boulangerie St-Méthode, Exceldor Foods, Goodfood Market and Sobeys advertised most frequently during preschooler-programming. General Mills, Kellogg's, the Topps Company, Parmalat and Post Foods advertised most frequently during child-programming, while Burger King, McDonald's, General Mills, Kellogg's and Wendy's advertised most frequently during adolescent-programming. CAI-participating companies were responsible for over half of the food advertising broadcast during programs targeted to children (55%), while they accounted for less than half of the food advertising aired during programs targeting preschoolers (24%), adolescents (41%) and adults (42%). Statutory food advertising restrictions are needed to limit food companies' targeting of young people on television in Canada. Novelty: Advertising from fast food restaurant chains dominated television programming targeted to adolescents in 2018. Advertising from breakfast cereal, candy, and snack manufacturers dominated television programming targeted at children in 2018. Over 100 Canadian and transnational companies contravened broadcast restrictions on advertising to preschoolers in 2018.

Reduction of traditional food consumption in Brazilian diet: trends and forecasting of bean consumption (2007-2030)

OBJECTIVE

To identify changes in traditional dietary behaviour through the evaluation of trends in bean consumption among adults in Brazil between 2007 and 2017 and to estimate its projections up to 2030.

DESIGN

Time-series analysis conducted with data from the Surveillance System for Protective and Risk Factors for Chronic Diseases by Telephone Survey (Vigitel) between 2007 and 2017. Weekly consumption of beans was analysed. Prais-Winsten regression evaluated trends for the entire period of study (2007-2017) and in two periods of analyses (2007-2011 and 2012-2017) for the complete set of the population and stratified by socio-demographic characteristics. Estimated prevalence projections were calculated up to the year 2030 using its tendency from 2012 to 2017.

SETTING

Brazil.

PARTICIPANTS

A probabilistic sample of 572 675 Brazilian adults aged ≥ 18 years.

RESULTS

Changes in traditional dietary pattern were identified. Regular consumption of beans (≥ 5 d/week) presented a stable prevalence trend for the total population in the complete and the first analysed period, but a significant decrease in the second half (67·5 % to 59·5 %) among both genders, all age groups and educational levels (except for ≥12 years). The higher magnitude of regular consumption of beans will occur up to the year of 2025 for the total population (46·9 %), when it will be less frequent in the week.

CONCLUSION

Reductions in the weekly consumption of beans may represent the weakness of a traditional food culture in a globalised food system. By 2025, regular consumption of beans will cease to be the predominant habit in the country.

An accountability evaluation for the responsible use of celebrity endorsement by the food and beverage industry to promote healthy food environments for young Americans: A narrative review to inform obesity prevention policy

Research has shown that celebrity endorsement is a marketing strategy primarily used to promote highly processed food and beverage products to children and adolescents, which negatively influences their diet quality and increases their risks of obesity. This study conducted an accountability evaluation to examine government, expert, and industry policies, guidelines, recommendations, and practices regarding using celebrity endorsement to support healthy marketing environment for young Americans. This study used the National Academy of Medicine's LEAD principles (i.e., locate, evaluate, and assemble evidence to inform decisions) to identify and synthesize relevant evidence between January 2000 and December 2019. We categorized the evidence in a five-step accountability framework and assigned each step a progress score (i.e., none, limited, some, and extensive). The findings showed that the US government made no progress to appoint an independent empowered body to evaluate celebrity endorsement practices. Stakeholders made some progress to take and hold industry and government to account and limited progress to share the account and to strengthen accountability structures. We suggest actions for diverse stakeholders to substantially strengthen accountability structures to ensure that celebrity endorsement is used to promote only healthy food environments to reduce obesity risks for young Americans.

Relationship between Marketing to Children on Food Labeling and Critical Nutrient Content in Processed and Ultra-Processed Products Sold in Supermarkets in Lima, Peru

Consumption of ultra-processed foods has increased alarmingly, representing a risk to children’s health. Different techniques in marketing to kids (M2K) used on food labels are influencing the purchasing decisions of these products. This study aims to provide useful information about M2K found in labeling of food products sold in a supermarket chain in Lima, Peru and to determine its relationship with critical nutrient content. This was an observational, correlational, descriptive study. Data were collected by photographing the front-of-pack (FoP) of 2747 product labels sold in three supermarkets in Lima, but only those that met all the inclusion criteria were evaluated (n = 1092). A relationship was found between the use of techniques in marketing to kids and the level of critical nutrient regarding saturated fat (PR = 0.56; CI95%: 0.52–0.63), total sugar (PR = 1.70; CI95%: 1.64–1.77), and sodium (PR = 1.05; CI95%: 1.03–1.07). Particularly with sugar, the presence of M2K is a risk factor. New regulatory policies for the use of these food labeling techniques should be implemented to improve children’s health at the population level.

Can counter-advertising diminish persuasive effects of conventional and pseudo-healthy unhealthy food product advertising on parents?: an experimental study

Background

To help address rising rates of obesity in children, evidence is needed concerning impacts of common forms of marketing for unhealthy child-oriented food products and the efficacy of educational interventions in counteracting any detrimental impacts of such marketing. This study aims to explore parents’ responses to advertising for unhealthy children’s food products that employ different types of persuasive appeals and test whether a counter-advertising intervention exposing industry motives and marketing strategies can bolster parents’ resistance to influence by unhealthy product advertising.

Methods

N = 1613 Australian parents were randomly assigned to view online either a: (A) non-food ad (control); (B) conventional confectionery ad (highlighting sensory benefits of the product); (C) pseudo-healthy confectionery ad (promoting sensory benefits and health attributes of the product); (D) conventional confectionery ad + counter-ad (employing inoculation-style messaging and narrative communication elements); (E) pseudo-healthy confectionery ad + counter-ad. Parents then viewed various snacks, including those promoted in the food ads and counter-ad. Parents nominated their preferred product, then rated the products.

Results

Exposure to the conventional confectionery ad increased parents’ preference for the advertised product, enhanced perceptions of the product’s healthiness and reduced sugar content and boosted brand attitude. Exposure to the pseudo-healthy confectionery ad increased parents’ preference for the advertised product, and enhanced perceptions of healthiness, fibre content and lower sugar content. The counter-ad diminished, but did not eliminate, product ad effects on parents’ purchasing preference, product perceptions and brand attitudes. The counter-ad also prompted parents to perceive processed foods as less healthy, higher in sugar and lower in fibre and may have increased support for advertising regulation.

Conclusions

Exposure to unhealthy product advertising promoted favourable perceptions of products and increased preferences for advertised products among parents. Counter-advertising interventions may bolster parents’ resistance to persuasion by unhealthy product advertising and empower parents to more accurately evaluate advertised food products.

Advertising Unhealthy Food to Children: on the Importance of Regulations, Parenting Styles, and Media Literacy

Purpose of Review

Childhood obesity is a global health concern. And a number of studies have indicated that food promotions affect children’s food attitudes, preferences, and food choices for foods high in fat and sugar, which potentially impacts children’s body weight development. This review showcases how children are affected by food promotions, why companies even target children with their promotional efforts, and what makes children so susceptible to promotion of unhealthy food. In addition, this review discusses how regulations, parental styles, and individual media literacy skills can help to contain the potential detrimental effects of food promotions on children’s health.

Recent Findings

The recent findings indicate that children are affected by food promotions in their preference for unhealthy food and beverages in selection tasks shortly conducted after exposure. Furthermore, results indicate significant effects of food marketing, including enhanced attitudes, preferences, and increased consumption of marketed (predominantly unhealthy) foods connected with a wide range of marketing strategies. Children are particularly vulnerable to promotional efforts and react to it strongly due to their still developing cognitive and social skills as well as their lack in inhibitory control.

Summary

This review proposes an applied focus that discusses pathways for regulators, parents, and educators. In the light of the discussed results, a large number of studies on food promotion indicate that there is need to react. In all these measures, however, it is of relevance to consider children’s developmental stages to effectively counteract and respond to the potential detrimental effects of food promotions on children’s long-term weight development.

The Nutritional Profile of Food Advertising for School-Aged Children via Television: A Longitudinal Approach

The prevalence of childhood obesity continues to increase. Screen time, one of the most documented reasons for the obesogenic environment, enhances childhood obesity, since advertisements for unhealthy food products are still broadcast on channels for children. This is presently one of the main challenges for the government in Spain, since the current laws and obligations are not updated. This study aims to analyze food advertising aimed at children on Spanish television in 2013 and 2018 on children's and general channels to test the effect of laws and obligations over time. In total, we viewed 512 h of the most viewed channels, two children's and two general channels, during the week and on weekends during specific periods of 2013 and 2018. Food advertising was categorized as core, non-core, and other food advertisement (CFA, NCFA, and OFA, respectively) according to the nutritional profile. A total of 2935 adverts were analyzed, 1263 in 2013 and 1672 in 2018. A higher proportion of NCFAs were broadcast on children's channels than in prior years, rising from 52.2% to 69.8% (p < 0.001). Nowadays, the risk of watching NCFAs on children's channels compared to general channels turns out to be higher (Odds ratio > 2.5; p < 0.001), due to exposure to adverts for high-sugar and high-fat foods such as cakes, muffins, cookies, and fried and frozen meals rich in fat. In conclusion, the trends of nutritional profiles in food advertising on television are worsening over time, since the prevalence of NCFAs was higher in 2018 than in 2013. Currently, CFAs are not mainly broadcast on children's channels, confirming high-risk exposure to non-core food advertising by watching them. Thus, food advertising laws and obligations should be adapted to increase compliance.

Beverage Advertisement Receptivity Associated With Sugary Drink Intake and Harm Perceptions Among California Adolescents

PURPOSE

Evaluate associations of adolescents' beverage marketing receptivity with sugar-sweetened beverage (SSB) perceived harm and intake.

DESIGN

School-based cross-sectional health behavior survey.

SETTING

Seven rural schools in California, 2019-2020.

SUBJECTS

815 student participants in grades 9 or 10.

MEASURES

Participants viewed 6 beverage advertisement images with brand obscured, randomly selected from a larger pool. Ads for telecommunications products were an internal control. Receptivity was a composite of recognizing, liking, and identifying the displayed brand (later categorized: low, moderate, high). Weekly SSB servings were measured with a quantitative food frequency questionnaire and perceived SSB harm as 4 levels ("no harm" to "a lot").

ANALYSIS

Outcomes SSB intake (binomial regression) and perceived harm (ordered logistic regression) were modeled according to advertisement receptivity (independent variable), with multiple imputation, school-level clustering, and adjustment for presumed confounders (gender, age, screen time, etc.).

RESULTS

In covariable-adjusted models, greater beverage advertisement receptivity independently predicted higher SSB intake (ratio of SSB servings, high vs. low receptivity: 1.48 [95% CI: 1.15, 1.89]) and lower perceived SSB harm (odds ratio, high vs. low receptivity: 0.59 [0.40, 0.88]). Perceived SSB harm was inversely associated with SSB intake.

CONCLUSION

Beverage advertisement receptivity was associated with less perceived SSB harm and greater SSB consumption in this population. Policy strategies, including marketing restrictions or counter-marketing campaigns could potentially reduce SSB consumption and improve health.

Food Marketing in an Obesogenic Environment: a Narrative Overview of the Potential of Healthy Food Promotion to Children and Adults

Purpose of Review

There is abundant evidence that food marketing influences children’s and adults’ food preferences and consumption. As such, exposure to unhealthy food marketing is a widely acknowledged risk factor contributing to the development of overweight and obesity. Less is known about the effects of healthy food promotion on people’s dietary behavior. This narrative review describes research from the past 5 years focused on the effects of healthy food marketing on children’s and adults’ food preferences and dietary intake. Our aim is to gain insight into the potential effects and mechanistic underpinnings of healthy food promotion, thereby building on existing knowledge on underlying mechanisms of the effectiveness of unhealthy food marketing.

Recent Findings

Only a small number of studies directly examined the effects of healthy food promotion on children’s and adults’ dietary behavior. Most studies targeted children’s fruit and/or vegetable intake and used a variety of marketing techniques, ranging from television adverts to social media influencer marketing. Six out of ten studies found a positive effect of healthy food promotion, indicating that healthy food marketing has the potential to influence dietary behavior.

Summary

Food marketing is highly effective in stimulating and reinforcing food consumption, in particular for energy-dense foods. Further investigation and experimentation into the efficiency and effectiveness of healthy food promotion are needed to determine how marketing techniques could be used to improve dietary behavior. The healthy food promotion model provides a framework for future research in this area.

Awareness of marketing for high fat, salt or sugar foods, and the association with higher weekly consumption among adolescents: a rejoinder to the UK government's consultations on marketing regulation

OBJECTIVE

Exposure to marketing for foods high in fat, salt or sugar (HFSS) reportedly influences consumption, nutritional knowledge and diet-related health among adolescents. In 2018/2019, the UK government held two consultations about introducing new restrictions on marketing for HFSS foods. To reinforce why these restrictions are needed, we examined adolescents' awareness of marketing for HFSS foods, and the association between past month awareness and weekly HFSS food consumption.

DESIGN

Cross-sectional survey that measured past month awareness of ten marketing activities for HFSS foods (1 = everyday; 6 = not in last month). Frequencies were converted into aggregate past month awareness across marketing activities and grouped into three categories (low/medium/high). Consumption was self-reported for fifteen foods (twelve HFSS) (1 = few times/d; 9 = never). For each food, frequency was divided into higher/lower weekly consumption.

SETTING

United Kingdom.

PARTICIPANTS

11-19-year-olds (n 3348).

RESULTS

Most adolescents (90·8 %) reported awareness of a least one marketing activity for HFSS foods, and at least half reported seeing ≥70 instances in the past month. Television, social media and price offers were the marketing activities most frequently reported. Awareness was associated with higher weekly consumption for ten of the twelve HFSS foods. For example, those reporting medium marketing awareness were 1·5 times more likely to report higher weekly consumption of cakes/biscuits compared with those reporting low awareness (AOR = 1·51, P = 0·012). The likelihood of higher weekly HFSS food consumption increased relative to the level of marketing awareness.

CONCLUSIONS

Assuming there is a causal relationship between marketing awareness and consumption, the restrictions proposed by the UK government are likely to help reduce HFSS consumption.

Selling second best: how infant formula marketing works

Background

Despite the clear policy intent to contain it, the marketing of formula milk remains widespread, powerful and successful. This paper examines how it works.

Methods

The study comprised a mix of secondary analysis of business databases and qualitative interviews with marketing practitioners, some of whom had previously worked in formula marketing.

Results

The World Health Assembly Code aims to shield parents from unfair commercial pressures by stopping the inappropriate promotion of infant formula. In reality marketing remains widespread because some countries (e.g. the USA) have not adopted the Code, and elsewhere industry has developed follow-on and specialist milks with which they promote formula by proxy. The World Health Assembly has tried to close these loopholes by extending its Code to these products; but the marketing continues. The campaigns use emotional appeals to reach out to and build relationships with parents and especially mothers. Evocative brands give these approaches a human face. The advent of social media has made it easier to pose as the friend and supporter of parents; it is also providing companies with a rich stream of personal data with which they hone and target their campaigns.

The formula industry is dominated by a small number of extremely powerful multinational corporations with the resources to buy the best global marketing expertise. Like all corporations they are governed by the fiduciary imperative which puts the pursuit of profits ahead of all other concerns. This mix of fiscal power, sophisticated marketing, and single-mindedness is causing great harm to public health.

Conclusions

Formula marketing is widespread and using powerful emotional techniques to sell parents a product that is vastly inferior to breast milk. There is an urgent need to update and strengthen regulation.

A Snapshot of European Children's Eating Habits: Results from the Fourth Round of the WHO European Childhood Obesity Surveillance Initiative (COSI)

Consuming a healthy diet in childhood helps to protect against malnutrition and noncommunicable diseases (NCDs). This cross-sectional study described the diets of 132,489 children aged six to nine years from 23 countries participating in round four (2015-2017) of the WHO European Childhood Obesity Surveillance Initiative (COSI). Children's parents or caregivers were asked to complete a questionnaire that contained indicators of energy-balance-related behaviors (including diet). For each country, we calculated the percentage of children who consumed breakfast, fruit, vegetables, sweet snacks or soft drinks "every day", "most days (four to six days per week)", "some days (one to three days per week)", or "never or less than once a week". We reported these results stratified by country, sex, and region. On a daily basis, most children (78.5%) consumed breakfast, fewer than half (42.5%) consumed fruit, fewer than a quarter (22.6%) consumed fresh vegetables, and around one in ten consumed sweet snacks or soft drinks (10.3% and 9.4%, respectively); however, there were large between-country differences. This paper highlights an urgent need to create healthier food and drink environments, reinforce health systems to promote healthy diets, and continue to support child nutrition and obesity surveillance.

Measuring the Power of Food Marketing to Children: a Review of Recent Literature

PURPOSE OF REVIEW

This scoping review examines literature from the past 5 years (June 2014 to June 2019) across three databases (PubMed, MEDLINE, and Scopus) to detail how the persuasive power of child-targeted food marketing content is addressed and evaluated in current research, to document trends and gaps in research, and to identify opportunities for future focus.

RECENT FINDINGS

Eighty relevant studies were identified, with varied approaches related to examining food marketing techniques to children (i.e., experimental, survey, meta-analyses, mixed methods, content analyses, focus groups). Few studies specifically defined power, and studies differed in terms of techniques examined. Spokes-characters were the predominant marketing technique measured; television was the platform most analyzed; and dominant messages focused on health/nutrition, taste appeals, and appeals to fun/pleasure. Mapping the current landscape when it comes to the power of food marketing to children reveals concrete details about particular platforms, methods, and strategies, as well as opportunities for future research-particularly with respect to definitions and techniques monitored, digital platforms, qualitative research, and tracking changes in targeted marketing techniques over time.

The Digital Media Environment and Cardiovascular Risk in Children

Children today are exposed to multiple forms of digital media including traditional (eg, televisions, computers) and newer mobile devices (eg, smartphones, tablets, etc). As the digital media environment evolves, it is important that health care providers and policymakers adapt to develop, implement, and evaluate strategies to ameliorate its effects on health. In this article we provide an overview of the literature on the relationship between the digital media environment and cardiovascular risk factors in childhood. Existing evidence on the relationship between digital media environment and cardiovascular risk in infants, children, and youth are reported. Potential mechanisms underpinning the relationship between the digital media environment and cardiovascular disease risk in children such as the displacement of movement behaviours, food and beverage marketing to children, and eating while viewing were explored. National and international guidelines aimed at addressing the digital media environment are highlighted, and suggestions for future research and guideline development are provided. Action-oriented professional recommendations for health care providers, families, and children are urgently needed. As the prevalence of screen use in childhood continues to exceed those of past generations, concern about the effects and strategies to reduce harm including cardiovascular outcomes must remain a top public health priority.

The Effects of Foods Embedded in Entertainment Media on Children's Food Choices and Food Intake: A Systematic Review and Meta-Analyses

While watching or playing with media, children are often confronted with food appearances. These food portrayals might be a potential factor that affects a child's dietary behaviors. We aimed to comprehensively expound the effects of these types of food appearances on dietary outcomes of children. Our objectives were to synthetize the evidence of the experiments that study the effects of foods embedded in children's entertainment media throughout a systematic review, to conduct two meta-analyses (food choice and intake) in order to quantify the effects, and to examine to what extent the effects of foods embedded in entertainment media varies across different moderating variables. We conducted a systematic search of five databases for studies published up to July 2018 regarding terms related to children and foods embedded in entertainment media. We identified 26 eligible articles, of which 13 (20 effect sizes) and 7 (13 effect sizes) were considered for a meta-analysis on food choice and intake, respectively. Most of the studies were assessed as having a middle risk of bias. Overall, food being embedded in entertainment media is a strategy that affects the eating behaviors of children. As most of the embedded foods in the included studies had low nutritional values, urgent measures are needed to address the problem of childhood obesity.

The Power of Packaging: A Scoping Review and Assessment of Child-Targeted Food Packaging

Child-targeted food marketing is a significant public health concern, prompting calls for its regulation. Product packaging is a powerful form of food marketing aimed at children, yet no published studies examine the range of literature on the topic or the "power" of its marketing techniques. This study attempts such a task. Providing a systematic scoping review of the literature on child-targeted food packaging, we assesses the nutritional profile of these foods, the types of foods examined, and the creative strategies used to attract children. Fifty-seven full text articles were reviewed. Results identify high level trends in methodological approaches (content analysis, 38%), outcomes measured (exposure, 44%) and with respect to age. Studies examining the nutritional profile of child-targeted packaged foods use various models, classifying from anywhere from 41% to 97% of products as unhealthy. Content analyses track the prevalence of child-targeted techniques (cartoon characters as the most frequently measured), while other studies assess their effectiveness. Overall, this scoping review offers important insights into the differences between techniques tracked and those measured for effectiveness in existing literature, and identifies gaps for future research around the question of persuasive power-particularly when it comes to children's age and the specific types of techniques examined.

Nutrition Education in the Australian New South Wales Primary School Curriculum: Knowledge and Attitudes of Students and Parents

In NSW, Australia, the views of primary-school aged children and their parents in regard to the importance of nutrition education at school are unclear. The aim of the current study was to explore children’s knowledge of nutrition and eating habits and to identify gaps that future school nutrition education programs could target. Students aged 9 to 12 years and their parents (n = 21 dyads) were invited to participate in semi-structured interviews, complete a nutrition knowledge questionnaire, and perform a “healthy-unhealthy” food sorting task in a University food laboratory. Among the children, nutrition knowledge scores concerning “serves & portions” of common foods were lowest, identifying a gap in knowledge related to portion size. All children categorized fruits, vegetables, cola, and water correctly as “healthy” or “unhealthy” in the sorting task, but not for the sausage and muesli bar, suggesting that further support categorising processed foods may be needed. The interviews indicated that parents do actively try to teach their children about nutrition, although they reported feeling uncertain about their own level of nutrition knowledge. Children and parents indicated that there is very little nutrition education in school and more is needed. This research could be used to inform future curriculum components related to nutrition education for primary school children.

The Effect of the Promotion of Vegetables by a Social Influencer on Adolescents' Subsequent Vegetable Intake: A Pilot Study

Marketers have found new ways of reaching adolescents on social platforms. Previous studies have shown that advertising effectively increases the intake of unhealthy foods while not so much is known about the promotion of healthier foods. Therefore, the main aim of the present experimental pilot study was to examine if promoting red peppers by a popular social influencer on social media (Instagram) increased subsequent actual vegetable intake among adolescents. We used a randomized between-subject design with 132 adolescents (age: 13–16 y). Adolescents were exposed to an Instagram post by a highly popular social influencer with vegetables (n = 44) or energy-dense snacks (n = 44) or were in the control condition (n = 44). The main outcome was vegetable intake. Results showed no effect of the popular social influencer promoting vegetables on the intake of vegetables. No moderation effects were found for parasocial interaction and persuasion knowledge. Bayesian results were consistent with the results and supported evidence against the effect of the experimental condition. Worldwide, youth do not consume the recommended amount of fruit and vegetables, making it important to examine if mere exposure or different forms of food promotion techniques for healthier foods are effective in increasing the intake of these foods.

See, Like, Share, Remember: Adolescents' Responses to Unhealthy-, Healthy- and Non-Food Advertising in Social Media

Media-saturated digital environments seek to influence social media users’ behaviour, including through marketing. The World Health Organization has identified food marketing, including advertising for unhealthy items, as detrimental to health, and in many countries, regulation restricts such marketing and advertising to younger children. Yet regulation rarely addresses adolescents and few studies have examined their responses to social media advertising. In two studies, we examined adolescents’ attention, memory and social responses to advertising posts, including interactions between product types and source of posts. We hypothesized adolescents would respond more positively to unhealthy food advertising compared to healthy food or non-food advertising, and more positively to ads shared by peers or celebrities than to ads shared by a brand. Outcomes measured were (1a) social responses (likelihood to ‘share’, attitude to peer); (1b) brand memory (recall, recognition) and (2) attention (eye-tracking fixation duration and count). Participants were 151 adolescent social media users (Study 1: n = 72; 13–14 years; M = 13.56 years, SD = 0.5; Study 2: n = 79, 13–17 years, M = 15.37 years, SD = 1.351). They viewed 36 fictitious Facebook profile feeds created to show age-typical content. In a 3 × 3 factorial design, each contained an advertising post that varied by content (healthy/unhealthy/non-food) and source (peer/celebrity/company). Generalised linear mixed models showed that advertisements for unhealthy food evoked significantly more positive responses, compared to non-food and healthy food, on 5 of 6 measures: adolescents were more likely to wish to ‘share’ unhealthy posts; rated peers more positively when they had unhealthy posts in their feeds; recalled and recognised a greater number of unhealthy food brands; and viewed unhealthy advertising posts for longer. Interactions with sources (peers, celebrities and companies) were more complex but also favoured unhealthy food advertising. Implications are that regulation of unhealthy food advertising should address adolescents and digital media.

Adolescents' Reactions to Adverts for Fast-Food and Confectionery Brands That are High in Fat, Salt, and/or Sugar (HFSS), and Possible Implications for Future Research and Regulation: Findings from a Cross-Sectional Survey of 11-19 Year Olds in the United Kingdom

The influence that marketing for foods high in fat, salt, and/or sugar (HFSS) has on adolescents extends beyond a dose-response relationship between exposure and consumption. It is also important to explore how marketing shapes or reinforces product/brand attitudes, and whether this varies by demography and Body Mass Index (BMI). To examine this, a cross-sectional survey was conducted with 11-19 year olds in the United Kingdom (n = 3348). Participants watched 30 s video adverts for a fast-food and confectionery brand. For each advert, participants reported reactions on eight measures (e.g., 1 = Makes [product] seem unpopular choice-5 = Makes [product] seem popular choice), which were binary coded based on whether a positive reaction was reported (Yes/No). At least half of adolescents had positive reactions to both adverts for 5/8 measures. Positive reactions had associations with age, gender and, to a lesser extent, BMI. For example, 11-15 year olds were more likely than 16-19 year olds to report appeal to their age group for the fast-food (OR = 1.33, 95% CI: 1.13-1.58) and confectionery advert (OR= 1.79, 95% CI: 1.51-2.11). If these reactions are typical of other HFSS products, future research and regulatory change should examine whether additional controls on the content of HFSS marketing, for example mandated health or nutritional information and revised definitions of youth appeal, offer additional protection to young people.

Examining the Relationship between Youth-Targeted Food Marketing Expenditures and the Demographics of Social Media Followers

Background: To determine how many adolescents follow food/beverage brands on Instagram and Twitter, and examine associations between brands’ youth-targeted marketing practices and percentages of adolescent followers. Methods: We purchased data from Demographics Pro to characterize the demographics of Twitter and Instagram users who followed 27 of the most highly advertised fast food, snack, and drink brands in 2019. We used one-sample t-tests to compare percentages of adolescent followers of the selected brands’ accounts versus all social media accounts, independent samples t-tests to compare followers of sugary versus low-calorie drink brands, and linear regression to examine associations between youth-targeted marketing practices and the percentages of adolescent followers. Results: An estimated 6.2 million adolescents followed the selected brands. A higher percentage of adolescents followed the selected brands’ accounts (9.2%) compared to any account on Twitter (1.2%) (p < 0.001), but not Instagram. A higher percentage of adolescents followed sugary (7.9%) versus low-calorie drink brands (4.3%) on Instagram (p = 0.02), but we observed the opposite pattern for adults on Twitter and Instagram. Television advertising expenditures were positively associated with percentages of adolescent followers of the selected brands on Twitter (p = 0.03), but not Instagram. Conclusions: Food and sugary drink brands maintain millions of adolescent followers on social media.

Exposure to Food and Beverage Advertising on Television among Canadian Adolescents, 2011 to 2016

Adolescents represent a key audience for food advertisers, however there is little evidence of adolescent exposure to food marketing in Canada. This study examined trends in Canadian adolescents’ exposure to food advertising on television. To do so, data on 19 food categories were licensed from Nielsen Media Research for May 2011, 2013, and 2016 for the broadcasting market of Toronto, Canada. The average number of advertisements viewed by adolescents aged 12–17 years on 31 television stations during the month of May each year was estimated using television ratings data. Findings revealed that between May 2011 and May 2016, the total number of food advertisements aired on all television stations increased by 4%, while adolescents’ average exposure to food advertising decreased by 31%, going from 221 ads in May 2011 to 154 in May 2016. In May 2016, the advertising of fast food and sugary drinks dominated, relative to other categories, accounting for 42% and 11% of all exposures, respectively. The findings demonstrate a declining trend in exposure to television food advertising among Canadian adolescents, which may be due to shifts in media consumption. These data may serve as a benchmark for monitoring and evaluating future food marketing policies in Canada.

"It's Just Addictive People That Make Addictive Videos": Children's Understanding of and Attitudes Towards Influencer Marketing of Food and Beverages by YouTube Video Bloggers

Exposure to influencer marketing of foods and beverages high in fat, sugar, and/or salt (HFSS) increases children's immediate intake. This study qualitatively explored children's understanding of, and attitudes towards, this marketing, to elucidate potential mechanisms through which exposure affects behavior. In six focus groups (n = 4) children (10-11 years) were shown a YouTube video featuring influencer marketing of an HFSS product. Inductive thematic analysis identified six themes from children's discussions of this marketing: (1) YouTubers fill a gap in children's lives, (2) the accessibility of YouTubers increases children's understanding of their actions, (3) influencer marketing impacts all-the influencer, the brand, and the viewer, (4) attitudes towards influencer marketing are most affected by a YouTuber's familiarity, (5) YouTuber influencer marketing is effective because they are not 'strangers', (6) children feel able to resist influencer marketing of HFSS products. Children had an understanding of the persuasive intent of this marketing, and although most were sceptical, familiar YouTubers elicited particularly sympathetic attitudes. Children felt affected by influencer marketing of HFSS products, but believed they were able to resist it. Beyond theoretical insight, this study adds to the growing body of evidence to suggest children's exposure to HFSS influencer marketing should be reduced.

Do bedroom screens and the mealtime environment shape different trajectories of child overweight and obesity? Research using the Growing Up in Scotland study

OBJECTIVE

To investigate how mealtime setting, mealtime interaction and bedroom screens are associated with different trajectories of child overweight and obesity, using a population sample.

METHODS

Growth mixture modelling used data from children in the Growing Up in Scotland Study born in 2004/5 (boys n = 2085, girls n = 1991) to identify trajectories of overweight or obesity across four time points, from 46 to 122 months. Using data from children present at all sweeps, and combining sexes (n = 2810), mutually adjusted associations between primary exposures (mealtime setting, mealtime interaction and bedroom screens) and trajectory class were explored in multinomial models; controlling for early life factors, household organisation and routines, and children's diet patterns, overall screen use, physical activity and sleep.

RESULTS

Five trajectories were identified in both sexes: Low Risk (68% of sample), Decreasing Overweight (9%), Increasing Overweight (12%), High/Stable Overweight (6%) and High/Increasing Obesity (5%). Compared with the Low Risk trajectory, High/Increasing Obesity and High/Stable Overweight trajectories were characterised by early increases in bedroom screen access (respective relative risk ratios (RRR) and 95% confidence intervals: 2.55 [1.30-5.00]; 1.62 [1.01-2.57]). An informal meal setting (involving mealtime screen use, not eating in a dining area and not sitting at a table) characterised the High/Increasing Obesity and Increasing Overweight trajectories (respective RRRs compared with Low Risk trajectory: 3.67 [1.99-6.77]; 1.75 [1.17-2.62]). Positive mealtime interaction was associated with membership of the Increasing Overweight trajectory (RRR 1.64 [1.13-2.36]).

CONCLUSION

Bedroom screen access and informal mealtime environments were associated with higher-risk overweight and obesity trajectories in a representative sample of Scottish children, after adjusting for a wide range of confounders. Findings may challenge the notion that positive mealtime interaction is protective. Promoting mealtimes in a screen-free dining area and removing screens from bedrooms may help combat childhood obesity.

Prevalence of Child-Directed Marketing on Breakfast Cereal Packages before and after Chile's Food Marketing Law: A Pre- and Post-Quantitative Content Analysis

Food marketing has been identified as a contributing factor in childhood obesity, prompting global health organizations to recommend restrictions on unhealthy food marketing to children. Chile has responded to this recommendation with a restriction on child-directed marketing for products that exceed certain regulation-defined thresholds in sugars, saturated fats, sodium, or calories. Child-directed strategies are allowed for products that do not exceed these thresholds. To evaluate changes in marketing due to this restriction, we examined differences in the use of child-directed strategies on breakfast cereal packages that exceeded the defined thresholds vs. those that did not exceed the thresholds before (n = 168) and after (n = 153) the restriction was implemented. Photographs of cereal packages were taken from top supermarket chains in Santiago. Photographed cereals were classified as “high-in” if they exceeded any nutrient threshold described in the regulation. We found that the percentage of all cereal packages using child-directed strategies before implementation (36%) was significantly lower after implementation (21%), p < 0.05. This overall decrease is due to the decrease we found in the percentage of “high-in” cereals using child-directed strategies after implementation (43% before implementation, 15% after implementation), p < 0.05. In contrast, a greater percentage of packages that did not qualify as “high-in” used child-directed strategies after implementation (30%) compared with before implementation (8%), p < 0.05. The results suggest that the Chilean food marketing regulation can be effective at reducing the use of child-directed marketing for unhealthy food products.

Understanding the rise of cardiometabolic diseases in low- and middle-income countries

Increases in the prevalence of noncommunicable diseases (NCDs), particularly cardiometabolic diseases such as cardiovascular disease, stroke and diabetes, and their major risk factors have not been uniform across settings: for example, cardiovascular disease mortality has declined over recent decades in high-income countries but increased in low- and middle-income countries (LMICs). The factors contributing to this rise are varied and are influenced by environmental, social, political and commercial determinants of health, among other factors. This Review focuses on understanding the rise of cardiometabolic diseases in LMICs, with particular emphasis on obesity and its drivers, together with broader environmental and macro determinants of health, as well as LMIC-based responses to counteract cardiometabolic diseases.

Tracking Kids' Food: Comparing the Nutritional Value and Marketing Appeals of Child-Targeted Supermarket Products Over Time

Marketing unhealthy foods negatively impacts children’s food preferences, dietary habits and health, prompting calls for regulations that will help to create an “enabling” food environment for children. One powerful food marketing technique is product packaging, but little is known about the nature or quality of child-targeted food products over time. This study assesses how child-targeted supermarket foods in Canada have transformed with respect to nutritional profile and types of marketing appeals (that is, the power of such marketing). Products from 2009 (n = 354) and from 2017 (n = 374) were first evaluated and compared in light of two established nutritional criteria, and then compared in terms of marketing techniques on packages. Overall, child-targeted supermarket foods did not improve nutritionally over time: 88% of child-targeted products (across both datasets) would not be permitted to be marketed to children, according to the World Health Organization (WHO) criteria, and sugar levels remained consistently high. Despite this poor nutritional quality, the use of nutrition claims increased significantly over time, as did the use of cartoon characters and appealing fonts to attract children’s attention. Character licensing—using characters from entertainment companies—remained consistent. The findings reveal the critical need to consider packaging as part of the strategy for protecting children from unhealthy food marketing. Given the poor nutritional quality and appealing nature of child-oriented supermarket foods, food product packaging needs to be included in the WHO’s call to improve the restrictions on unhealthy food marketing to children.
