An accountability evaluation for the industry's responsible use of brand mascots and licensed media characters to market a healthy diet to American children

Corporate strategies that target children are controversial given the link between food marketing and childhood obesity. This case study explored diverse stakeholders' accountability expectations and actions for industry policies and practices that used popular cartoon brand mascots and media characters to promote food products to American children. We reviewed five electronic databases and Internet sources between January 2000 and January 2015. Evidence (n = 90) was selected based upon the Institute of Medicine's LEAD principles (i.e. locate, evaluate, assemble evidence to inform decisions) and organized into two tables: peer‐reviewed articles, books and grey‐literature reports (n = 34); and media stories, news releases and public testimony (n = 56). A four‐step accountability framework was used to evaluate accountability structures. The results showed that moderate progress was achieved by stakeholders to take and share the account, limited progress to hold industry and government to account, and limited progress to strengthen accountability structures. Between 2006 and 2015, the U.S. Children's Food and Beverage Advertising Initiative lacked clear policies for companies to use brand mascots and media characters on food packages, in merchandising, and as toy giveaways and premiums. Government, industry and civil society can substantially strengthen their accountability for these food marketing practices to ensure healthy food environments for children.     

Associations between predictors of children's dietary intake and socioeconomic position: a systematic review of the literature

Socioeconomically disadvantaged children are at higher risk of consuming poor diets, in particular less fruits and vegetables and more non‐core foods and sweetened beverages. Currently the drivers of socioeconomically related differences in children's dietary intake are not well understood. This systematic review explored whether dietary predictors vary for children of different socioeconomic circumstances. Seven databases and reference lists of included material were searched for studies investigating predictors of 9–13‐year‐old children's diet in relation to socioeconomic position. Individual‐ and population‐based cross‐sectional, cohort and epidemiological studies published in English and conducted in developed countries were included. Twenty‐eight studies were included in this review; most were conducted in Europe (n = 12) or North America (n = 10). The most frequently used indicators of socioeconomic position were parent education and occupation. Predictors of children's dietary intake varied among children of different socioeconomic circumstances. Socioeconomic position was consistently associated with children's nutrition knowledge, parent modelling, home food availability and accessibility. Indeterminate associations with socioeconomic position were observed for parent feeding practices and food environment near school. Differences in the determinants of eating between socioeconomic groups provide a better understanding of the drivers of socioeconomic disparities in dietary intake, and how to develop targeted intervention strategies.     

The impact of initiatives to limit the advertising of food and beverage products to children: a systematic review

In response to increasing evidence that advertising of foods and beverages affects children's food choices and food intake, several national governments and many of the world's larger food and beverage manufacturers have acted to restrict the marketing of their products to children or to advertise only ‘better for you’ products or ‘healthier dietary choices’ to children. Independent assessment of the impact of these pledges has been difficult due to the different criteria being used in regulatory and self‐regulatory regimes. In this paper, we undertook a systematic review to examine the data available on levels of exposure of children to the advertising of less healthy foods since the introduction of the statutory and voluntary codes. The results indicate a sharp division in the evidence, with scientific, peer‐reviewed papers showing that high levels of such advertising of less healthy foods continue to be found in several different countries worldwide. In contrast, the evidence provided in industry‐sponsored reports indicates a remarkably high adherence to voluntary codes. We conclude that adherence to voluntary codes may not sufficiently reduce the advertising of foods which undermine healthy diets, or reduce children's exposure to this advertising.     

Influence of unhealthy food and beverage marketing on children's dietary intake and preference: a systematic review and meta‐analysis of randomized trials

Marketing of foods and beverages high in fat, sugar and salt are suggested to contribute to poor dietary behaviours in children and diet‐related diseases later in life. This systematic review and meta‐analysis of randomized trials aimed to assess the effects of unhealthy food and beverage marketing on dietary intake (grams or kilocalories) and dietary preference (preference score or percentage of participants who selected specific foods/beverages) among children 2 to 18 years of age. We searched MEDLINE, EMBASE and PsycINFO up to January 2015 for terms related to advertising, unhealthy foods or beverages among children. Randomized trials that assessed the effects of unhealthy food and beverage marketing compared with non‐dietary advertisement or no advertisement in children were considered eligible. Two authors independently extracted information on study characteristics and outcomes of interest and assessed risk of bias and the overall quality of evidence using grade methodology. Meta‐analysis was conducted separately for dietary intake and preference using a random‐effects model. We identified 29 eligible studies, of which 17 studies were included for meta‐analysis of dietary preference and nine for meta‐analysis of dietary intake. Almost half of the studies were at high risk of bias. Our meta‐analysis showed that in children exposed to unhealthy dietary marketing, dietary intake significantly increased (mean difference [MD] = 30.4 kcal, 95% confidence interval [CI] 2.9 to 57.9, and MD = 4.8 g, 95%CI 0.8 to 8.8) during or shortly after exposure to advertisements. Similarly, children exposed to the unhealthy dietary marketing had a higher risk of selecting the advertised foods or beverages (relative risk = 1.1, 95%CI 1.0 to 1.2; P = 0.052). The evidence indicates that unhealthy food and beverage marketing increases dietary intake (moderate quality evidence) and preference (moderate to low quality evidence) for energy‐dense, low‐nutrition food and beverage. Unhealthy food and beverage marketing increased dietary intake and influenced dietary preference in children during or shortly after exposure to advertisements. © 2016 World Obesity     

Evidence of a possible link between obesogenic food advertising and child overweight

A recent review of the literature concluded that advertising of foods on television may influence children's food choices and encourage unhealthy diets, but the review acknowledged there was a lack of clear evidence in coming to this conclusion. The present paper examines ecological evidence for a link between advertising to children and the risk of overweight using data from surveys of advertising on children's television and estimates of the prevalence of overweight among children, in the USA, Australia and eight European countries. A significant association was found between the proportion of children overweight and the numbers of advertisements per hour on children's television, especially those advertisements that encourage the consumption of energy‐dense, micronutrient‐poor foods (r = 0.81, P < 0.005). A weaker, negative association was found between the proportion of children overweight and the number of advertisements encouraging healthier diets (r = ?0.56, P < 0.10). The quantity of advertising on children's television appears to be related to the prevalence of excess body weight among children. Furthermore, the content of the advertising appears to have a specific effect. The findings justify the need for taking precautionary measures to reduce children's exposure to obesogenic marketing practices.     

Global benchmarking of children's exposure to television advertising of unhealthy foods and beverages across 22 countries

Restricting children's exposures to marketing of unhealthy foods and beverages is a global obesity prevention priority. Monitoring marketing exposures supports informed policymaking. This study presents a global overview of children's television advertising exposure to healthy and unhealthy products. Twenty‐two countries contributed data, captured between 2008 and 2017. Advertisements were coded for the nature of foods and beverages, using the 2015 World Health Organization (WHO) Europe Nutrient Profile Model (should be permitted/not‐permitted to be advertised). Peak viewing times were defined as the top five hour timeslots for children. On average, there were four times more advertisements for foods/beverages that should not be permitted than for permitted foods/beverages. The frequency of food/beverages advertisements that should not be permitted per hour was higher during peak viewing times compared with other times (P < 0.001). During peak viewing times, food and beverage advertisements that should not be permitted were higher in countries with industry self‐regulatory programmes for responsible advertising compared with countries with no policies. Globally, children are exposed to a large volume of television advertisements for unhealthy foods and beverages, despite the implementation of food industry programmes. Governments should enact regulation to protect children from television advertising of unhealthy products that undermine their health.     

Associations of maternal stress with children's weight‐related behaviours: a systematic literature review

Low adherence to guidelines for weight‐related behaviours (e.g. dietary intake and physical activity) among US children underscores the need to better understand how parental factors may influence children's obesity risk. In addition to most often acting as primary caregiver to their children, women are also known to experience greater levels of stress than men. This study systematically reviewed associations between maternal stress and children's weight‐related behaviours. Our search returned 14 eligible articles, representing 25 unique associations of maternal stress with a distinct child weight‐related behaviour (i.e. healthy diet [n = 3], unhealthy diet [n = 6], physical activity [n = 7] and sedentary behaviour [n = 9]). Overall, findings for the relationship between maternal stress and children's weight‐related behaviours were mixed, with no evidence for an association with children's healthy or unhealthy dietary intake, but fairly consistent evidence for the association of maternal stress with children's lower physical activity and higher sedentary behaviour. Recommendations for future research include prioritizing prospective designs, identifying moderators, and use of high‐resolution, real‐time data collection techniques to elucidate potential mechanisms.     

An accountability evaluation for the International Food & Beverage Alliance's Global Policy on Marketing Communications to Children to reduce obesity: A narrative review to inform policy

United Nations (UN) organizations have urged governments to restrict the marketing of unhealthy food and nonalcoholic beverage products to children. This study conducted an accountability evaluation for the International Food & Beverage Alliance's (IFBA's) Global Policy on Marketing Communications to Children (Global Policy) compared with UN and other best‐practice recommendations. We used the National Academy of Medicine's LEAD (ie, locate, evaluate, assemble evidence to inform decisions) framework to identify evidence (January 2004 to October 2018). We assigned a progress score (ie, none, limited, some, extensive) for five accountability steps. No progress was made to appoint an empowered body to evaluate IFBA's Global Policy. IFBA and the Access to Nutrition Foundation made some progress to take and share the account. Diverse actors made no progress to hold IFBA to account for nonadherence or to strengthen accountability structures for future compliance. IFBA could strengthen its Global Policy to align with best practices. UN organizations and other stakeholders should encourage IFBA firms to restrict the marketing of unhealthy foods and beverages to reduce children's obesity risk. This evaluation is relevant to all firms and industry associations that market products to children that undermine their diet and health.     

Obesity and the food system transformation in Latin America

The Latin America and the Caribbean (LAC) region faces a major diet‐related health problem accompanied by enormous economic and social costs. The shifts in diet are profound: major shifts in intake of less‐healthful low‐nutrient‐density foods and sugary beverages, changes in away‐from‐home eating and snacking and rapid shifts towards very high levels of overweight and obesity among all ages along with, in some countries, high burdens of stunting. Diet changes have occurred in parallel to, and in two‐way causality with, changes in the broad food system – the set of supply chains from farms, through midstream segments of processing, wholesale and logistics, to downstream segments of retail and food service (restaurants and fast food chains). An essential contribution of this piece is to marry and integrate the nutrition transition literature with the literature on the economics of food system transformation. These two literatures and debates have been to date largely ‘two ships passing in the night’. This review documents in‐depth the recent history of rapid growth and transformation of that broad food system in LAC, with the rapid rise of supermarkets, large processors, fast food chains and food logistics firms. The transformation is the story of a ‘double‐edged sword’, showing its links to various negative diet side trends, e.g. the rise of consumption of fast food and highly processed food, as well as in parallel, to various positive trends, e.g. the reduction of the cost of food, de‐seasonalization, increase of convenience of food preparation reducing women's time associated with that and increase of availability of some nutritious foods like meat and dairy. We view the transformation of the food system, as well as certain aspects of diet change linked to long‐run changes in employment and demographics (e.g. the quest for convenience), as broad parameters that will endure for the next decades without truly major regulatory and fiscal changes. We then focus in on what are the steps that are being and can be taken to curb the negative effects on diet of these changes. We show that countries in LAC are already among the global leaders in initiating demand‐related solutions via taxation and marketing controls. But we also show that this is only a small step forward. To shift LAC's food supply towards prices that incentivize consumption of healthier diets and demand away from the less healthy component is not simple and will not happen immediately. We must be cognizant that ultimately, food industry firms must be incentivized to market the components of healthy diets. This will primarily need to be via selective taxes and subsidies, marketing controls, as well as food quality regulations, consumer education and, in the medium term, consumers' desires to combine healthier foods with their ongoing quest for convenience in the face of busy lives. In the end, the food industry in LAC will orient itself towards profitable solutions, ie those demanded by the broad mass of consumers.     

Framing obesity: the framing contest between industry and public health at the New Zealand inquiry into obesity

Drawing on submissions to the 2006–2007 New Zealand Inquiry into Obesity and Type 2 Diabetes, this article outlines how the food and marketing industries (industry) and the public health sector framed the issue of obesity. The analysis revealed that industry framed obesity as a consequence of poor lifestyle choices attributed largely to knowledge, cultural or other character deficits. Industry argued that lack of physical activity rather than increased food consumption was the dominant cause of obesity. In contrast, public health groups positioned obesity as a normal response to an obesogenic environment, characterized by the ubiquitous marketing and availability of low‐cost, energy‐dense/nutrient‐poor foods. For public health groups, increased consumption of energy‐dense/nutrient‐poor foods was positioned as the dominant cause of obesity. Many public health submitters also suggested that social inequalities contributed to obesity. Industry emphasized education as the key solution to obesity, while public health groups argued for regulation of the activities of the food and marketing industries, and policies to address wider determinants of health and social inequalities. Identifying and documenting these frames, by making transparent the interests of the frame's sponsors, contributes to greater understanding of the wider policy context around obesity and provides useful information for public health advocacy.     

Children's and parents' opinions on the sport‐related food environment: a systematic review

Sport is a key setting for interventions to address child obesity given its obesogenic nature. Understanding children's and parents' opinions on the sport‐related food environment is critical in developing effective programmes and policies to improve children's health. This systematic review synthesizes quantitative and qualitative research examining children's and parents' opinions on the sport‐related food environment. During July 2016, a range of electronic databases of academic and grey literature were searched. Thirty‐two publications (11 including children, 17 parents and 4 both) were included for review. The publications were assessed using the Analysis Grid for Environments Linked to Obesity framework to categorize the sport‐related food environment into the physical, sociocultural, economic and political environments. The literature available investigating children's and parents' opinions of the sport‐related food environment suggests that many children and parents consider the environment neither conducive to nor supportive of children's healthy food behaviours or wider health and well‐being. Both groups would likely support actions to change and improve it. This systematic review found that original research specifically investigating children's and parents' perspectives on almost all aspects of the sport‐related food environment is limited. Thus, there is scope for further investigation into this important part of children's food environments.     

Childhood obesity: a societal problem to solve

In contrast to other threats to American children's health, the treatment and prevention of childhood obesity are considered the responsibility of individual children and their parents. This pressure exists in the context of the societal stigmatization of overweight children and the powerful environmental inducements aimed directly at children to eat nutritionally poor foods. Parents of overweight children are left in the difficult position of fearing the social and health consequences of their child's obesity, and fighting a losing battle against the omnipotent presence of the media and constant exposure to unhealthy foods. This paper brings together several literatures to provide a comprehensive examination of the major challenges facing obese children and their families. In particular, this paper documents the extent of stigmatization towards overweight children and reviews evidence of the conflicting advice given to parents about how to help children develop healthful eating in the face of biological and learned food preferences. We conclude with a call for a shift in thinking about the role of our society in the aetiology, treatment and prevention of childhood obesity.     

Nitrate and Nitrite Intake and the Risk for Type 1 Diabetes in Finnish Children

The intakes of nitrate and nitrite of children and their parents from food and drinking water were estimated in a Finnish nation-wide case-control study on the epidemiology of Type 1 diabetes. The study population consisted of 684 case and 595 control children; 548 case-control pairs of fathers; and 620 case-control pairs of mothers. The consumption frequencies of foods which are important sources of nitrate and nitrite were assessed by structured questionnaire. Nitrate and nitrite concentration data were collected from Finnish water works. Diabetic children's and their mothers' daily dietary intake of nitrite was greater compared with that of control children and mothers (for case and control children 0.9 mg vs 0.8 mg, for case and control mothers 0.9 mg vs 0.8 mg, p<0.001). Case mothers compared with control mothers received less (p<0.05) nitrate from their diet. No differences were observed in the intake of nitrate or nitrite from drinking water. Dietary nitrite intake of children (odds ratios and 95% confidence intervals for the second, third, and fourth quartile 1.16, 0.82–1.65; 1.49, 1.06–2.10; 2.32, 1.67–3.24, respectively) and mothers (odds ratios and 95% confidence intervals for the second, third, and fourth quartile 1.15, 0.76–1.74; 1.29, 0.87–1.91; 1.98, 1.35–2.90, respectively) was positively associated with the risk for Type 1 diabetes independently from length of mother's education, child's or mother's age, place of residence or mother's smoking status. The present study gives supporting evidence that dietary nitrites, from which N-nitroso compounds can be formed in foods and in the human body, are associated with the development of Type 1 diabetes in man.     

The effect of screen advertising on children's dietary intake: A systematic review and meta‐analysis

Evidence indicates that screen advertising for unhealthy food results in significant increases in dietary intake among children. This review was undertaken with the main aim of estimating the quantitative effect of screen advertising in experimental and nonexperimental conditions on children's dietary intake. Systematic searches were undertaken of interdisciplinary databases. Studies from 1980 to April 2018, all geography and languages, were included; participants were children and adolescents aged between 2 and 18 years; the intervention was screen advertising; and the outcome was dietary intake. Meta‐analyses were conducted for measured and nonmeasured outcomes. Food advertising was found to increase dietary intake among children (age range 2‐14, mean 8.8 years) in experimental conditions for television (TV) advertising and advergames. Meta‐analysis revealed that children exposed to food advertising on TV (11 studies) and advergames (five studies) respectively consumed an average 60.0 kcal (95% confidence interval [CI], 3.1‐116.9) and 53.2 kcal (95% CI, 31.5‐74.9) more than children exposed to nonfood advertising. There was also an effect by body mass index (BMI). Findings from nonexperimental studies revealed that exposure to TV food advertising was positively associated with and predictive of dietary intake in children. Short‐term exposure to unhealthy food advertising on TV and advergames increases immediate calorie consumption in children.     

A systematic review of persuasive marketing techniques to promote food to children on television

The ubiquitous marketing of energy‐dense, nutrient‐poor food and beverages is a key modifiable influence on childhood dietary patterns and obesity. Much of the research on television food advertising is focused on identifying and quantifying unhealthy food marketing with comparatively few studies examining persuasive marketing techniques to promote unhealthy food to children. This review identifies the most frequently documented persuasive marketing techniques to promote food to children via television. A systematic search of eight online databases using key search terms identified 267 unique articles. Thirty‐eight articles met the inclusion criteria. A narrative synthesis of the reviewed studies revealed the most commonly reported persuasive techniques used on television to promote food to children. These were the use of premium offers, promotional characters, nutrition and health‐related claims, the theme of taste, and the emotional appeal of fun. Identifying and documenting these commonly reported persuasive marketing techniques to promote food to children on television is critical for the monitoring and evaluation of advertising codes and industry pledges and the development of further regulation in this area. This has a strong potential to curbing the international obesity epidemic besieging children throughout the world.     

Should obese patients be counselled to follow a low‐glycaemic index diet? No

In diabetes research the glycaemic index (GI) of carbohydrates has long been recognized and a low GI is recommended. The same is now often the case in lipid research. Recently, a new debate has arisen around whether a low‐GI diet should also be advocated for appetite‐ and long‐term body weight control. A systematic review was performed of published human intervention studies comparing the effects of high‐ and low‐GI foods or diets on appetite, food intake, energy expenditure and body weight. In a total of 31 short‐term studies (<1 d), low‐GI foods were associated with greater satiety or reduced hunger in 15 studies, whereas reduced satiety or no differences were seen in 16 other studies. Low‐GI foods reduced ad libitum food intake in seven studies, but not in eight other studies. In 20 longer‐term studies (<6 months), a weight loss on a low‐GI diet was seen in four and on a high‐GI diet in two, with no difference recorded in 14. The average weight loss was 1.5 kg on a low‐GI diet and 1.6 kg on a high‐GI diet. To conclude, there is no evidence at present that low‐GI foods are superior to high‐GI foods in regard to long‐term body weight control. However, the ideal long‐term study where ad libitum intake and fluctuations in body weight are permitted, and the diets are similar in all aspects except GI, has not yet been performed.     

Sensory influences on food intake control: moving beyond palatability

The sensory experience of eating is an important determinant of food intake control, often attributed to the positive hedonic response associated with certain sensory cues. However, palatability is just one aspect of the sensory experience. Sensory cues based on a food's sight, smell, taste and texture are operational before, during and after an eating event. The focus of this review is to look beyond palatability and highlight recent advances in our understanding of how certain sensory characteristics can be used to promote better energy intake control. We consider the role of visual and odour cues in identifying food in the near environment, guiding food choice and memory for eating, and highlight the ways in which tastes and textures influence meal size and the development of satiety after consumption. Considering sensory characteristics as a functional feature of the foods and beverages we consume provides the opportunity for research to identify how sensory enhancements might be combined with energy reduction in otherwise palatable foods to optimize short‐term energy intake regulation in the current food environment. Moving forward, the challenge for sensory nutritional science will be to assess the longer‐term impact of these principles on weight management.     

Media food marketing and eating outcomes among pre‐adolescents and adolescents: A systematic review and meta‐analysis

The media marketing's effect on child and adult eating has been extensively researched, yet, little is known about its effect on adolescents. The aim of this review is to synthesize available research on the relation between media food marketing and eating‐related cognitions, attitudes, and behaviors among pre‐adolescents (8‐11) and adolescents (12‐19). We systematically screened and retrieved 9324 articles, of which 28 were included in the review‐analysis and 19 in the meta‐analysis. Robust variance estimation with random effect weights indicated a positive small standard effect size (d = 0.26, P < .001) of media food marketing on all unhealthy eating outcomes, and a subgroup analysis revealed a small effect size (d = 0.26, P < .001) on unhealthy eating behaviors specifically. Another subgroup analysis among adolescents revealed an effect of marketing (d = 0.22, P < .05) on unhealthy eating outcomes. This review demonstrates the significance of media marketing on eating in pre‐adolescents and adolescents, and highlights limitations in the food marketing and adolescent eating literature specific to eating outcomes and marketing media studied and research designs utilized. We call for properly designed food marketing research exploring digital media's effect on eating attitudes and cognitions, especially among older adolescents.     

Complementary feeding patterns in Europe with a special focus on Italy

Early nutrition is considered to be crucial for development of persistent obesity in later life. The aim of this paper is to present an overview of complementary feeding patterns across European countries.Most European infants introduce solid foods earlier than 6 completed months of age as recommended by WHO. The commonest risk factors for early introduction of solid foods have been shown to be smoking mothers of young age, low SES and no breastfeeding. The foods most frequently introduced as first solids are fruit and cereals followed by other foods that vary depending on the country of residence and the infants' type of feeding. Insufficient updated information has been made available in Europe in terms of infants' nutrient intake during complementary feeding, as well as on the potential acute metabolic effects of complementary feeding. Websites, e-forums and blogs on complementary feeding are widely spread in the web. The recipes and daily menus published in food industry websites are often nutritionally incorrect. Baby led-weaning (BLW) is based on the principle that babies, upon being started on complementary foods, should be allowed to eat whatever food they want (regular family foods included) in its normal shape. No nutrient intake and metabolic data are nevertheless available about BLW. The current scenario in terms of our understanding of complementary feeding in Europe opens several new research avenues.Not using and not improving our current knowledge of nutrition to improve children's health represents an infringement of children's rights.
