The Impact on Dietary Outcomes of Celebrities and Influencers in Marketing Unhealthy Foods to Children: A Systematic Review and Meta-Analysis. Nutrients 2022; 14:nu14030434. [PMID: 35276800 PMCID: PMC8837952 DOI: 10.3390/nu14030434] [Citation(s) in RCA: 13] [Impact Index Per Article: 6.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/22/2021] [Revised: 01/14/2022] [Accepted: 01/17/2022] [Indexed: 01/02/2023] Open
Abstract
Celebrities, including influencers, are commonly used to market products that are high in fat, sugar, and salt (HFSS) to children but the impact on dietary outcomes has been unclear. The primary aim of this study was to systematically review the literature and quantify the impact of celebrities in HFSS marketing on children’s dietary outcomes. We searched eight databases and included studies from all countries and languages published from 2009 until August 2021. Participants were defined as under 16 years, exposure was marketing for HFSS products with a celebrity, and the outcomes were dietary preference, purchasing behaviors, and consumption of HFSS products. We were able to conduct a meta-analysis for consumption outcomes. Seven articles met the inclusion criteria, of which three were included in the meta-analysis. Under experimental conditions, the use of celebrities in HFSS marketing compared to non-food marketing was found to significantly increase consumption of the marketed HFSS product by 56.4 kcals (p = 0.021). There was limited evidence on the impact on preference or purchase intentions and on the comparisons between use and non-use of celebrities and influencers.

Abstract
Adolescence is a pivotal point in the life course, characterised by transformative physical, cognitive, and emotional growth, an openness to change, and a drive to reshape the social environment. It offers unique opportunities to adopt changes in diet and physical activity that can persist into later life. Yet pre-existing nutritional problems, including micronutrient deficiencies, food insecurity, and poor-quality diets, persist at the same time as adolescents face the rapid emergence of an obesity epidemic. Adolescent growth and nutrition has been largely overlooked in intervention and policy research. Most intervention studies have emphasised micronutrient supplementation, with few taking into account the multiple drivers of adolescent diets. This Series paper highlights that effective interventions and policies will need to cut across sectors; be supported by multifaceted and multilevel policy; and extend across education, health, food systems, social protection, and digital media. Better data standardisation and systems will be essential in coordinating and monitoring these responses. In a context of shifts in planetary ecosystems and commercial drivers, resilient food systems will need to both ensure access to healthy and affordable foods and provide the infrastructure and incentives for continuing physical activity. Intergenerational partnerships with young people will be essential in bringing about transformative change and ensuring that food policies reflect their needs and aspirations.

Abstract
The detrimental impact of currently disproportionate amounts of digital food advertising for processed foods high in sugar, salt, and fat (HSSF) on children's food intake and dietary health is well-documented. The potential of digital healthy food advertising to encourage healthy eating in children is much less researched. A pre-test post-test control group design was used to compare the effect of specifically designed, television-style advertisements for healthy food versus toys on 172 three-to seven-year-old children's exclusively healthy food intake (vegetable, fruit, whole-grain) in five nurseries in Germany. Within- and between-group comparisons demonstrated the effectiveness of healthy food advertising exposure to increase children's healthy food intake. Three exposures to a 1-min-advertisement for healthy food were sufficient to increase children's healthy food intake by as much as three portions. Children in the control condition ate less healthy foods following viewing of a control advertisement (a matched toy advertisement). We concluded that digital healthy food advertising is likely to increase children's healthy food intake sufficiently to help children meet daily recommended amounts of vegetables, fruit, or whole-grain bread, and that this encouragement may be required as decreases in healthy food intake were found when healthy foods were merely available.

Abstract
Currently, food marketing for unhealthy foods is omnipresent. Foods high in fat, salt, and sugar (HFSS) are advertised intensively on several media platforms, including digital platforms that are increasingly used by children, such as social media, and can be bought almost everywhere. This could contribute to the obesity epidemic that we are facing. As the majority of children and adolescents do not eat the recommended amount of fruits and vegetables (F&V), which leads to chronic diseases, we need to change the obesogenic environment to a healthogenic environment. Reducing the marketing of energy-dense snacks to children and increasing the promotion of healthier foods, such as fruits and vegetables, may be an effective and necessary instrument to improve the dietary intake of children and reduce the risk of their experiencing some chronic diseases later in life. With this focused narrative review, we provide an overview of how children and adolescents react to food promotions and how food promotional efforts might be a useful tool to increase the attractiveness of fruit and vegetables. This review therefore contributes to the question of how changing the advertising and media environment of children and adolescents could help create a world where the healthy choice is the easier choice, which would reduce childhood obesity and improve children’s health, as well as to make the food system more sustainable.

The Home Environment Interview and associations with energy balance behaviours and body weight in school-aged children - a feasibility, reliability, and validity study. Int J Behav Nutr Phys Act 2021; 18:167. [PMID: 34949200 PMCID: PMC8698661 DOI: 10.1186/s12966-021-01235-3] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/01/2021] [Accepted: 12/06/2021] [Indexed: 01/11/2023] Open
Abstract
BACKGROUND The home environment is thought to influence children's weight trajectories. However, few studies utilise composite measures of the home environment to examine associations with energy balance behaviours and weight. The present study aimed to adapt and update a comprehensive measure of the obesogenic home environment previously developed for pre-schoolers, and explore associations with school-aged children's energy balance behaviours and weight. METHODS Families from the Gemini cohort (n = 149) completed the Home Environment Interview (HEI) via telephone when their children were 12 years old. The HEI comprises four composite scores: one for each domain (food, activity and media) of the environment, as well as a score for the overall obesogenic home environment. The primary caregiver also reported each child's height and weight (using standard scales and height charts), diet, physical activity and sedentary screen-based behaviours. A test-retest sample (n = 20) of caregivers completed the HEI a second time, 7-14 days after the initial interview, to establish test-retest reliability. RESULTS Children (n = 298) living in 'higher-risk' home environments (a 1 unit increase in the HEI obesogenic risk score) were less likely to consume fruits (OR; 95% CI = 0.40; 0.26-0.61, p < 0.001), and vegetables (0.30; 0.18-0.52, p < 0.001), and more likely to consume energy-dense snack foods (1.71; 1.08-2.69, p = 0.022), convenience foods (2.58; 1.64-4.05, p < 0.001), and fast foods (3.09; 1.90-5.04, p < 0.001). Children living in more obesogenic home environments also engaged in more screen-time (β (SE) = 4.55 (0.78), p < 0.001), spent more time playing video games (β (SE) = 1.56 (0.43), p < 0.001), and were less physically active (OR; 95% CI = 0.57; 0.40-0.80, p < 0.01). Additionally, there was a positive association between higher-risk overall home environment composite score and higher BMI-SDS (β (SE) = 0.23 (0.09), p < 0.01). This finding was mirrored for the home media composite (β (SE) = 0.12 (0.03), p < 0.001). The individual home food and activity composite scores were not associated with BMI-SDS. CONCLUSION Findings reveal associations between the overall obesogenic home environment and dietary intake, activity levels and screen-based sedentary behaviours, as well as BMI in 12 year olds. These findings suggest that the home environment, and in particular the home media environment, may be an important target for obesity prevention strategies.

Abstract
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 06.00 to midnight (864 h). Food advertisements were coded using three nutrient profiling models. The number of children and young people watching television each year was 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 3 years (P < 0·0001). The mean rate of unhealthy food advertising on weekdays was 10·4 advertisements/h (2015) and 9·5 advertisements/h (2018). Corresponding rates for weekend days were 8·1 and 7·3 advertisements/h, 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 was watching television. Consequently, government regulation and regular monitoring should reflect the evolving food marketing environment.

Abstract
BACKGROUND The relation between socioeconomic position (SEP) and obesity measured by body mass index (BMI), a measure of weight for height, has been extensively reviewed in children, showing consistent associations between disadvantaged SEP and higher BMI in high-income countries (HICs) and lower BMI in middle-income countries (MICs). Fat mass (FM), a more accurate measure of adiposity, and fat-free mass (FFM) are not captured by BMI, but have been shown to track from childhood to adulthood, and be important for cardiovascular health and functional outcomes in later life. It is not clear whether body composition is associated with SEP. We systematically reviewed the association between SEP and body composition in childhood. METHODS A systematic review was carried out following PRISMA guidelines. The protocol was pre-registered with PROSPERO (CRD42019119937). Original studies in the English language, which examined the association between SEP and body composition in childhood, were included. An electronic search of three databases was conducted. Two independent reviewers carried out screening, data extraction and quality assessment. Due to heterogeneity in results, a narrative synthesis was conducted. Heterogeneity in findings according to SEP, sex, body composition measure and country income level was investigated. RESULTS 50 papers were included, the majority from HICs. No papers were from low-income countries. Disadvantage in childhood was associated with greater FM and lower FFM in HICs, but with lower FM and lower FFM in MICs. When measures of FFM indexed to height were used there was no evidence of associations with SEP. In HICs, more studies reported associations between disadvantaged SEP and higher FM among girls comparative to boys. CONCLUSIONS Inequalities in FM are evident in HICs and, in the opposite direction, in MICs and follow similar trends to inequalities for BMI. Inequalities in height are likely important in understanding inequalities in FFM.

Abstract
Objective: To quantify the potential population-wide costs, number of individuals reached, and impact on obesity of five effective interventions to reduce children's television viewing if implemented nationally. Study Design: Utilizing evidence from systematic reviews, the Childhood Obesity Intervention Cost Effectiveness Study (CHOICES) microsimulation model estimated the cost, population reach, and impact on childhood obesity from 2020 to 2030 of five hypothetical policy strategies to reduce the negative impact of children's TV exposure: (1) eliminating the tax deductibility of food and beverage advertising; (2) targeting TV reduction during home visiting programs; (3) motivational interviewing to reduce home television time at Women, Infants, and Children (WIC) clinic visits; (4) adoption of a television-reduction curriculum in child care; and (5) limiting noneducational television in licensed child care settings. Results: Eliminating the tax deductibility of food advertising could reach the most children [106 million, 95% uncertainty interval (UI): 105-107 million], prevent the most cases of obesity (78,700, 95% UI: 30,200-130,000), and save more in health care costs than it costs to implement. Strategies targeting young children in child care and WIC also cost little to implement (between $0.19 and $32.73 per child reached), and, although reaching fewer children because of the restricted age range, were estimated to prevent between 25,500 (95% UI: 4600-59,300) and 35,400 (95% UI: 13,200-62,100) cases of obesity. Home visiting to reduce television viewing had high costs and a low reach. Conclusions: Interventions to reduce television exposure across a range of settings, if implemented widely, could help prevent childhood obesity in the population at relatively low cost.

Abstract
BACKGROUND Diets with high proportions of foods high in fat, sugar, and/or salt (HFSS) contribute to malnutrition and rising rates of childhood obesity, with effects throughout the life course. Given compelling evidence on the detrimental impact HFSS advertising has on children's diets, the World Health Organization unequivocally supports the adoption of restrictions on HFSS marketing and advertising. In February 2019, the Greater London Authority introduced novel restrictions on HFSS advertising across Transport for London (TfL), one of the most valuable out-of-home advertising estates. In this study, we examined whether and how commercial actors attempted to influence the development of these advertising restrictions. METHODS AND FINDINGS Using requests under the Freedom of Information Act, we obtained industry responses to the London Food Strategy consultation, correspondence between officials and key industry actors, and information on meetings. We used an existing model of corporate political activity, the Policy Dystopia Model, to systematically analyse arguments and activities used to counter the policy. The majority of food and advertising industry consultation respondents opposed the proposed advertising restrictions, many promoting voluntary approaches instead. Industry actors who supported the policy were predominantly smaller businesses. To oppose the policy, industry respondents deployed a range of strategies. They exaggerated potential costs and underplayed potential benefits of the policy, for instance, warning of negative economic consequences and questioning the evidence underlying the proposal. Despite challenging the evidence for the policy, they offered little evidence in support of their own claims. Commercial actors had significant access to the policy process and officials through the consultation and numerous meetings, yet attempted to increase access, for example, in applying to join the London Child Obesity Taskforce and inviting its members to events. They also employed coalition management, engaging directly and through business associations to amplify their arguments. Some advertising industry actors also raised the potential of legal challenges. The key limitation of this study is that our data focused on industry-policymaker interactions; thus, our findings are unable to present a comprehensive picture of political activity. CONCLUSIONS In this study, we identified substantial opposition from food and advertising industry actors to the TfL advertising restrictions. We mapped arguments and activities used to oppose the policy, which might help other public authorities anticipate industry efforts to prevent similar restrictions in HFSS advertising. Given the potential consequences of commercial influence in these kinds of policy spaces, public bodies should consider how they engage with industry actors.

Abstract
Snacks contribute nearly one-quarter of children's daily energy intake in the USA. Snack time therefore represents an opportunity for parents to provide foods with key nutrients. Instead, the most common snack foods are major contributors to children's consumption of added sugars and sodium. Parents face major barriers to providing healthier snacks, including perceptions of high cost and lack of child acceptance. We obtained both economic and qualitative data to inform and optimize interventions for parents to promote vegetable snacks for children. We conducted a survey with parents (n = 368) to estimate how much of a discount would influence vegetable snack purchases by estimating willingness-to-pay using the contingent valuation method, using baby-cut carrots as a sample product. We conducted three focus groups (n = 19) and 1 group interview (n = 2) with children to help understand how to increase the appeal of vegetable snacks. Most (70%) parents accepted the reference price for the vegetable snack. Among those who did not, contingent valuation analysis revealed that a mean discount of approximately 30% would shift consumers to purchasing the snack. Focus group results revealed that the appeal of vegetable snacks to children was influenced by how they were prepared and presented, and the child's familiarity with the vegetables and ability to choose among them. This study lays the groundwork for effective interventions to promote the provision of vegetable snacks by parents.

Parental perceptions and practices regarding sugar intake by school-aged children: A qualitative study with Portuguese parents. Appetite 2021; 166:105471. [PMID: 34147567 DOI: 10.1016/j.appet.2021.105471] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/28/2021] [Revised: 04/21/2021] [Accepted: 06/15/2021] [Indexed: 12/27/2022]
Abstract
Excessive sugar intake is one of the factors contributing to the alarming rates of childhood obesity and overweight in Portugal. Children's preferences and food consumption patterns are largely determined by the foods that are more familiar to them. Parents and caregivers are responsible for shaping children's eating habits since they are the ones who choose the food available in the household. The present study explores parental perceptions about sugar and sugar intake and its consequences on children's health. Moreover, we also examined the practices that parents use to regulate their children's diet, namely, to promote the consumption of desired foods (e.g., vegetables) and limit the intake of undesired food (e.g., sweets), and the perceived barriers and facilitators of sugar intake regulation. To this end, 42 interviews were conducted with parents of school-aged children (ages 6-10 years). A thematic analysis revealed that parents perceive sugar as highly negative (e.g., "evil", "poison", "addiction") and its consumption as harmful (e.g., hyperactivity; overweight). Nonetheless, the view that sugary food consumption is not necessarily problematic was also common. Indeed, most parents considered that sugar intake should be regulated but not forbidden. To control the intake of sugary foods (e.g., sodas, cookies), they reported using strategies such as restriction, explanation, or negotiation. Several barriers to sugar intake regulation were identified (e.g., birthday parties, parents' lack of knowledge), but also a few facilitators (e.g., bringing food from home to school). Our findings may inform the development of interventions or policies to promote healthier eating habits in school-age children.

Abstract
OBJECTIVES This paper examines the retail food environment in grocery and convenience stores across Nova Scotia with specific attention to prominence and promotion of foods and beverages, as well as in-store promotion of foods and beverages to children. METHODS A descriptive cross-sectional analysis of data on the availability, price, prominence, and promotion of foods and beverages classified as "healthier" and "less healthy" was undertaken as a part of a Nova Scotia Consumer Food Environment (NS-CFE) project. Data were collected in a random stratified sample of 47 grocery stores and 59 convenience stores by trained research assistants working in pairs using adapted Nutrition Environment Measures Survey Toronto grocery store (NEMS-S) and NEMS Corner Store (NEMS-CS) tools. RESULTS "Less healthy" snack foods and sugar-sweetened beverages were more prominently displayed than "healthier" options with an exception of cereal, at both grocery and convenience stores (all p < 0.001). Coke™ and fruit juice were more expensive than water in both grocery and convenience stores (both p ≤ 0.05). Significantly more child-specific strategies were used to promote "less healthy" compared with "healthier" options in both grocery and convenience stores (both p < 0.001). CONCLUSION Results of this study demonstrate that "less healthy" options are significantly more prominently displayed and more heavily marketed to all Nova Scotians, including children, in the retail food environment compared with items classified as "healthier". These findings indicate that there is a need for comprehensive structural changes to the retail food environment in Nova Scotia, to support population health.

Abstract
In March 2020 Italy went into lockdown due to COVID-19 pandemic and children changed rapidly their lifestyles with possible negative effects on their health status. An online survey collected data on eating habits, physical activity, perception/behaviour of 1027 Italian 2-11 years children during lockdown. The chi-square test was applied to test differences in proportions. Results showed a tendency of eating behaviour to worsen as children age and by areas. Only 32.3% of the children had high adherence to Mediterranean Diet, with better scores in 2-5 years children. 78.1% of the children stopped their habitual physical activity, with higher percentage among 6-11 and in Northern children; only 51.8% maintained some activities at home, playing mainly movement games/sports. Children spent more time on devices, missed school and friends, being more bored and less creative. This framework highlights the growing need for strategies to preserve children's health in this and future pandemics.

Abstract
Energy-dense food advertising affects children's eating behaviour. However, the impact of high-sugar food advertising specifically on the intake of sweet foods is underexplored. This study sought to determine whether children would increase their intake of sugar and total energy following high-sugar food advertising (relative to toy advertising) and whether dental health, weight status and socio-economic status (SES) would moderate any effect. In a crossover, randomised controlled trial, 101 UK children (forty male) aged 8-10 years were exposed to high-sugar food/beverage and toy advertisements embedded within a cartoon. Their subsequent intake of snack foods and beverages varying in sugar content was measured. A dental examination was performed, and height and weight measurements were taken. Home postcode provided by parents was used to assign participants to SES quintiles. Children consumed a significantly greater amount of energy (203·3 (95 % CI 56·5, 350·2) kJ (48·6 (95 % CI 13·5, 83·7) kcal); P = 0·007) and sugar (6·0 (95 % CI 1·3, 10·7) g; P = 0·012) following food advertisements compared with after toy advertisements. This was driven by increased intake of the items with most sugar (chocolate and jelly sweets). Children of healthy weight and with dental caries had the greatest intake response to food advertising exposure, but there were no differences by SES. Acute experimental food advertising exposure increases food intake in children. Specifically, high-sugar food and beverage advertising promotes the consumption of high-sugar food items. The debate around the negative health effects of food advertising on children should be widened to include dental health as well as overall dietary health and obesity.

Abstract
PURPOSE OF REVIEW The mechanistic role of sugar-sweetened beverage (SSB) in the etiology of obesity is undetermined. We address whether, compared to other foods, does consumption of SSB (1) automatically lead to failure to compensate for the energy it contains? (2) fail to elicit homeostatic hormone responses? (3) promote hedonic eating through activation of the brain's reward pathways? We followed the evidence to address: (4) Would restriction of targeted marketing of SSB and other unhealthy foods to vulnerable populations decrease their prevalence of obesity? RECENT FINDINGS The data are lacking to demonstrate that SSB consumption promotes body weight gain compared with isocaloric consumption of other beverages or foods and that this is linked to its failure to elicit adequate homeostatic hormone responses. However, more recent data have linked body weight gain to reward activation in the brain to palatable food cues and suggest that sweet tastes and SSB consumption heightens the reward response to food cues. Studies investigating the specificity of these responses have not been conducted. Nevertheless, the current data provide a biological basis to the body of evidence demonstrating that the targeted marketing (real life palatable food cues) of SSB and other unhealthy foods to vulnerable populations, including children and people of color and low socioeconomic status, is increasing their risk for obesity. While the mechanisms for the association between SSB consumption and body weight gain cannot be identified, current scientific evidence strongly suggests that proactive environmental measures to reduce exposure to palatable food cues in the form of targeting marketing will decrease the risk of obesity in vulnerable populations.

Abstract
OBJECTIVE To formally test a hierarchy of effects model linking exposure to television (TV) advertising for unhealthy foods with child body weight through purchase requests, purchases, and consumption. DESIGN A nationally representative cross-sectional online study in the United Kingdom. PARTICIPANTS A total of 2,260 parent-child dyads (children aged 7-11 years) recruited via online research panel; 55.7% boys, mean age 8.9 ± 1.4 years, mean body mass index z-score 1.25 ± 2.1. MAIN OUTCOME MEASURES Parents reported on child TV exposure and child height and weight. Children self-reported their frequency of (1) pestering for advertised foods, (2) purchase of unhealthy foods, and (3) consumption of unhealthy foods. ANALYSIS A structural equation model was applied to data. RESULTS As predicted, commercial TV exposure was indirectly associated with children's body mass index through purchasing and consumption through purchase requests. It was also directly associated with children's purchase requests, purchasing, and consumption of unhealthy foods. Associations between noncommercial TV and behavior or body weight outcomes, when found, were significantly weaker than for commercial exposure. CONCLUSIONS AND IMPLICATIONS This study provides insight into the likely behavioral pathways underpinning the effects of food marketing on diet and potentially body weight in children. Future longitudinal analyses would provide insight into causal inferences.

Abstract
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.

Abstract
Abstract
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.

Abstract
INTRODUCTION The HAVISA plan is a Spanish government's policy for the promotion of healthy lifestyles via health messages in television food advertisements. This study evaluated the positive or negative impact (health halo effect) of health messages on food choices and predisposition towards healthy habits of Spanish adolescents. METHODS Randomized controlled study in 11-14 years old adolescents. The intervention group watched television advertisements for unhealthy foods with HAVISA health messages, while the control group watched the same advertisements without them. A self-administered questionnaire measured participants' attitudes towards the products advertised, to diet and physical activity, and recognition of messages. Afterwards they chose between fruit and unhealthy snacks. The differences between the two groups were then compared. RESULTS A total of 27.2% of the control group versus 29.6% of the intervention group chose fruit (p = 0.54). Both groups displayed high desire for (7.24 vs. 7.40, p = 0.29) and intention to consume (6.67 vs. 6.73, p = 0.63) the unhealthy products advertised. There were no differences in perceived healthiness of these foods (4.11 vs. 4.19, p = 0.74), or perceived importance of a healthy diet (3.17 vs. 3.12, p = 0.55) or physical activity (4.53 vs. 4.51, p = 0.73). Desire for vegetables (2.49 vs. 2.66, p = 0.08) and fruit (3.15 vs. 3.30, p = 0.09) were higher in the intervention group, but the differences were not significant. Only 47.6% of participants noticed the presence of health messages; of these, 31% correctly recalled their content. CONCLUSION HAVISA health messages changed neither the attitudes nor immediate eating behaviors of adolescents. There was no immediate healthy-lifestyle promoter or adverse health halo effect, probably due to the messages' low prominence. Further research should evaluate the long-term effect of repeated exposure to health messages.

Abstract
Abstract
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.

Abstract
BACKGROUND Restrictions on the advertising of less-healthy foods and beverages is seen as one measure to tackle childhood obesity and is under active consideration by the UK government. Whilst evidence increasingly links this advertising to excess calorie intake, understanding of the potential impact of advertising restrictions on population health is limited. METHODS AND FINDINGS We used a proportional multi-state life table model to estimate the health impact of prohibiting the advertising of food and beverages high in fat, sugar, and salt (HFSS) from 05.30 hours to 21.00 hours (5:30 AM to 9:00 PM) on television in the UK. We used the following data to parameterise the model: children's exposure to HFSS advertising from AC Nielsen and Broadcasters' Audience Research Board (2015); effect of less-healthy food advertising on acute caloric intake in children from a published meta-analysis; population numbers and all-cause mortality rates from the Human Mortality Database for the UK (2015); body mass index distribution from the Health Survey for England (2016); disability weights for estimating disability-adjusted life years (DALYs) from the Global Burden of Disease Study; and healthcare costs from NHS England programme budgeting data. The main outcome measures were change in the percentage of the children (aged 5-17 years) with obesity defined using the International Obesity Task Force cut-points, and change in health status (DALYs). Monte Carlo analyses was used to estimate 95% uncertainty intervals (UIs). We estimate that if all HFSS advertising between 05.30 hours and 21.00 hours was withdrawn, UK children (n = 13,729,000), would see on average 1.5 fewer HFSS adverts per day and decrease caloric intake by 9.1 kcal (95% UI 0.5-17.7 kcal), which would reduce the number of children (aged 5-17 years) with obesity by 4.6% (95% UI 1.4%-9.5%) and with overweight (including obesity) by 3.6% (95% UI 1.1%-7.4%) This is equivalent to 40,000 (95% UI 12,000-81,000) fewer UK children with obesity, and 120,000 (95% UI 34,000-240,000) fewer with overweight. For children alive in 2015 (n = 13,729,000), this would avert 240,000 (95% UI 65,000-530,000) DALYs across their lifetime (i.e., followed from 2015 through to death), and result in a health-related net monetary benefit of £7.4 billion (95% UI £2.0 billion-£16 billion) to society. Under a scenario where all HFSS advertising is displaced to after 21.00 hours, rather than withdrawn, we estimate that the benefits would be reduced by around two-thirds. This is a modelling study and subject to uncertainty; we cannot fully and accurately account for all of the factors that would affect the impact of this policy if implemented. Whilst randomised trials show that children exposed to less-healthy food advertising consume more calories, there is uncertainty about the nature of the dose-response relationship between HFSS advertising and calorie intake. CONCLUSIONS Our results show that HFSS television advertising restrictions between 05.30 hours and 21.00 hours in the UK could make a meaningful contribution to reducing childhood obesity. We estimate that the impact on childhood obesity of this policy may be reduced by around two-thirds if adverts are displaced to after 21.00 hours rather than being withdrawn.

Abstract
The prevalence of childhood obesity has increased worldwide and various environmental factors have accelerated this trend. Several reports have suggested that food advertising causes childhood obesity. We proposed a review study to evaluate the relationship between TV food advertisements and obesity in children. By searching over electronic databases (including PubMed, Web of Science, Scopus, and Google Scholar), the reference lists of original studies, and reviews using key search terms, 1181 articles were identified. Out of these, only 9 articles met the inclusion and quality criteria. Most of the longitudinal study carried out at the national level have reported a significant association between commercial viewing and BMI in children. The duration of these studies varied between 7 months and 5 years. The children's TV viewing time was between 1.5 and 3.5 hours per day. Results of the reviewed studies have revealed a controversial attitude about the influence of TV food advertisements on obesity. However, three of four modeling studies indicated an increment in the prevalence of overweight and obesity following exposure to food advertisements. Further interventional and longitude studies are needed to achieve more precise results.

Abstract
Over the last 50 years, in parallel with the obesity epidemic, the prevalence of eating disorders has increased and presentations have changed. In this narrative review, we consider recent research exploring the implications of changing patterns of food consumption on metabolic and neurobiological pathways, a hitherto neglected area in eating disorder research. One of the major changes over this time has been the introduction of ultra-processed (NOVA-4) foods, which are gradually replacing unprocessed and minimally processed foods. This has resulted in the increased intake of various sugars and food additives worldwide, which has important metabolic consequences: triggering insulin and glucose response, stimulating appetite, and affecting multiple endocrine and neurobiological pathways, as well as the microbiome. A paradigm shift is needed in the conceptual framework by which the vulnerability to, and maintenance of, different eating disorders may be understood, by integrating recent knowledge of the individual metabolic responses to modern highly processed foods into existing psychological models. This could stimulate research and improve treatment outcomes.

Abstract
OBJECTIVE This study aimed to identify and meta-analyse the neuroimaging data and hence synthesise a brain map showing the neural correlates of watching food commercials. DESIGN Published studies were retrieved and included into the analysis if they evaluated brain responses to food commercials with functional MRI and reported results based on whole-brain analysis in standard brain coordinates. SETTING No additional restriction was placed on the search, such as the publication year and age of participants. PARTICIPANTS Seven papers that composed of a total of 442 participants fulfilled the inclusion criteria. All of them recruited children or adolescents. RESULTS Food commercials caused larger brain responses than nonfood counterparts in the cuneus on both hemispheres, which played a role in dietary self-control and modulation of food craving. Other brain regions involved in food commercials processing included the left culmen, left middle occipital gyrus and the right superior parietal lobule, which could be related to reward, emotional responses and habit formation. CONCLUSION These neural correlates may help explain the food choice and eating behaviours of children and adolescents that might be relevant to the development of obesity.

Abstract
PURPOSE Young adults are vulnerable to weight gain and dietary behaviours such as 'eating on the run' are likely contributors. The objective of this study was to examine eating and drinking behaviours during transport journeys in a sample of young adults using wearable cameras that take continuous images every 30 s. METHODS Seventy-eight 18-30 year olds wore an Autographer wearable camera for three consecutive days. Image coding schedules were designed to assess physical activity (included transportation) and diet. For the general description of data, frequency analysis was calculated as image number (percentage) and mean (± SD) or median (IQR) when appropriate. RESULTS A total of 281,041 images were coded and 32,529 (14%) of images involved transport. The median (IQR) camera wear time was 8 h per day (7-9 h). The camera images identified 52 participants (67%) either eating or drinking during transport (excluding water). A total of 143 eating and drinking occasions were identified, averaging 3 occasions per person over the three study days. Fifty five (38%) eating episodes were identified by the camera images of which 27 (49%) were discretionary and 88 (62%) drinking episodes were identified of which (45%) were discretionary. CONCLUSION This study confirms that transport is a potential setting for intervention. Young adults are consuming discretionary food and beverages during transport which may contribute to energy-dense diets and compromise diet quality. Substituting unhealthy with healthy food advertising and potentially prohibiting eating and drinking whilst on public transport is suggested.

Abstract
BACKGROUND Lifestyles habits such as eating unhealthy foodscommence at home and are associated with the development of obesity and comorbidities such as insulin resistance, metabolic syndrome, and chronic degenerative diseases, which are the main causes of death in adults. The present study compared changes in dietary habits, behaviors and metabolic profiles of obese children whose mothers attended at the hospital to group sessions, with those who received the usual nutritional consultation. METHODS Randomized clinical trial, 177 mother/obese child pairs participated, 90 in the intervention group and 87 in the control group. The intervention group attended six group education sessions to promote healthy eating, being this an alternative of change of habits in children with obesity. The control group received the usual nutritional consultation; both groups were followed up for 3 months. Frequency of food consumption, behaviors during feeding in the house and metabolic profile was evaluated. Mixed effect linear regression models were used to evaluate the effect of the intervention on the variables of interest, especially in HOMA-IR. RESULTS The intervention group reduced the filling of their dishes (p = 0.009), forcing the children to finish meals (p = 0.003) and food substitution (p < 0.001), moreover increased the consumption of roasted foods (p = 0.046), fruits (p = 0.002) and vegetables (p < 0.001). The children in the control group slightly increased HOMA-IR levels (0.51; 95% CI - 0.48 to 1.50), while the children in the intervention group significantly decreased (- 1.22; 95% CI - 2.28 to - 1.16). The difference in HOMA-IR between the control and intervention group at the end of the follow-up was - 1.67; 95% CI: - 3.11 to - 0.24. CONCLUSIONS The educational intervention improved some eating habits at home, as well as HOMA-IR levels; why we consider that it can be an extra resource in the management of childhood obesity.

Abstract
OBJECTIVE To describe food-industry sponsorships of associations active in the field of childhood nutrition and obesity prevention in Spain in 2017-2018. METHOD The associations were located at https://www.google.es/ using the words "society", "foundation" or "federation" in combination with the terms "nutrition", "obesity", "childhood", "paediatrics" and "diabetes". Sponsorship was defined as the declaration of funding received or the appearance of a food company logo on an association's website or in the programmes of its congresses or courses. The percentage of sponsored societies and its association with the existence of ethical codes was calculated using MS Excel. RESULTS 64% of the associations displayed some type of sponsorship, with this being most frequent among paediatric and nutrition societies, 83% and 80% respectively, and non-existent among public health societies. No association was found between the existence of an ethical code and sponsorship (odds ratio: 0.75; 95% confidence interval: 0.14-3.94). The leading corporate sponsors were Nestlé, Coca-Cola and Danone. Whereas the initiatives of sponsored societies were targeted at changing eating individual behaviours, those of unsponsored societies sought to promote changes in the food system and eating environments. CONCLUSIONS Food industry sponsorship of foundations and scientific societies is very widespread in Spain, except among public health associations. Unlike sponsored associations, those unsponsored propose policies opposed by the food industry, which are aimed at improving the system and food and eating environments.

Abstract
Obesity prevention policies are a priority for many governments and intergovernmental agencies. Policy makers not only use systematic reviews of effectiveness but also consider contextual issues including cost and cost‐effectiveness, equity, rights, acceptability and feasibility. To support their work, the present narrative review examines three contextual issues (costs, equity and acceptability) in relation to three policies for obesity prevention: sweetened beverage taxes, front‐of‐pack nutrition labelling and restrictions on advertising to children. Literature searches led to over 1100 documents, of which 125 informed the present review. Beverage taxes were found likely to be highly cost‐effective, moderately favourable for health equity, supported by the public (depending on the use of revenues) and by health professionals and civil society groups and opposed by commercial interests. Depending on the design, front‐of‐pack nutritional labelling is likely to be highly cost‐effective, moderately favourable for health equity, supported by the public, health professionals and civil society groups, and opposed by commercial interests. Restrictions on child‐directed advertising are likely to be highly cost‐effective in the longer term, moderately favourable for health equity, supported by the public, health professionals and civil society groups and opposed by commercial interests (unless voluntary). The evidence base needs strengthening, but the authors find that all three policies merit consideration by governmental authorities, and should be implemented to reduce obesity risk.

Abstract
AbstractObjectives:To examine the extent and characteristics of food and beverage (F&B) promotion in Hong Kong mass transit railway (MTR) stations in districts with different socioeconomic statuses (SES) and school density.Design:All advertisements located in the eight selected MTR stations were recorded by photographs or videos, and classified into F&B and non-F&B. The percentage of F&B advertisements and unhealthy F&B being promoted, and common persuasive marketing strategies used in F&B advertisements were compared between low v. high SES districts and school zones v. non-school zones.Setting:MTR stations in Hong Kong.Participants:Not applicable.Results:Of the 8064 advertisements documented, 861 (10·7 %) were F&B advertisements, promoting 1860 F&B items. More than half of the these were unhealthy foods. Stations in high SES districts or school zones tend to advertise more unhealthy items (high v. low SES: 55·8 v. 50·8 %, P = 0·049; school v. non-school: 60·8 v. 49·3 %, P < 0·001). More than one-third of the F&B advertisements recorded did not utilise any of those persuasive marketing techniques that were examined, and using models (13·9 %) or providing discounts (8·8 %) were the two most frequently used non-festival-related persuasive marketing strategies.Conclusions:Unhealthy F&B advertising in MTR stations is prevalent regardless of SES and school density, and persuasive marketing strategies were infrequently used. These suggest that a ban on unhealthy F&B advertising around schools or the use of persuasive marketing strategies alone would be ineffective in Hong Kong. To align with the recommendation from WHO, a universal ban of junk food advertising should be enacted.

Abstract
OBJECTIVE To analyse the extent and nature of food and beverage advertising on the three major Brazilian free-to-air television (TV) channels. DESIGN Cross-sectional study. A protocol developed for the International Network for Food and Obesity/Non-Communicable Diseases Research, Monitoring and Action Support was applied for data collection. A total of 432 h of TV programming was recorded from 06.00 to 24.00 hours, for eight non-consecutive and randomly selected days, in April 2018. All TV advertisements (ads) were analysed, and food-related ads were classified according to the NOVA classification system. Descriptive analyses were used to describe the number and type of ads, food categories and the distribution of ads throughout the day and time of the day. SETTING The three most popular free-to-air channels on Brazilian TV. PARTICIPANTS The study did not involve human subjects. RESULTS In total, 14·2 % (n 1156 out of 7991) of ads were food related (858 were specific food items). Approximately 91 % of food items ads included ultra-processed food (UPF) products. The top three most promoted products were soft drinks, alcoholic beverages and fast-food meals. Alcoholic beverage ads were more frequently broadcast in the evening. CONCLUSION The high risk of exposure of the Brazilian population to UPF ads should be considered a public health concern given the impact of unhealthy food advertising on people's food choices and health.

Abstract
New Zealand has the second highest overweight and obese child population in the Organisation for Economic Co-operation and Development (OECD). This paper evaluates whether New Zealand’s self-regulatory controls on the advertising of unhealthy food and beverages to children and young people adequately protects children from the exposure to, and power of, such marketing in order to limit its impact on children’s food and beverage preferences. First, an analysis of the relevant New Zealand Advertising Standards Authority (ASA) Codes was conducted, including the ASA Complaints Board and Appeals Board decisions from 2017–2019 to determine the application of the Codes in practice. Second, a public health law framework was applied to the self-regulatory system. Of the 16 complaints assessed, 12 were not upheld, and only one was upheld under the Children and Young People’s Advertising Code (CYPA Code). Three complaints were upheld under the Advertising Standards Code (ASC) but not the CYPA Code. An analysis of the Codes and their interpretation by the Complaints Board found that many facets of the public health law framework were not met. The self-regulatory system does not adequately protect children from the exposure to, and power of, unhealthy food and beverage marketing, and government-led, comprehensive, and enforceable marketing restrictions are required.

Abstract
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.

Abstract
The progressive rise in Canadian child obesity has paralleled trends in unhealthy food consumption. Industry has contributed to these trends through aggressive food and beverage marketing in various media and child settings. This study aimed to assess the extent of food and beverage advertising on television in Canada and compare the frequency of food advertising broadcasted during programs targeted to preschoolers, children, adolescents and adults. Annual advertising from 2018 was drawn from publicly available television program logs. Food and beverage advertisement rates and frequencies were compared by, target age group, television station, month and food category, using linear regression modelling and chi-square tests, in SAS version 9.4. Rates of food and beverage advertising differed significantly between the four target age groups, and varied significantly by television station and time of the year, in 2018. The proportion of advertisements for food and beverage products was significantly greater during preschooler-, child-, and adult-programming [5432 (54%), 142,451 (74%) and 2,886,628 (48%), respectively; p < 0.0001] compared to adolescent-programming [27,268 (42%)]. The proportion of advertisements promoting fast food was significantly greater among adolescent-programming [33,475 (51%), p < 0.0001] compared to other age groups. Legislation restricting food and beverage advertising is needed in Canada as current self-regulatory practices are failing to protect young people from unhealthy food advertising and its potential negative health effects.

Abstract
Background World Health Organisation (WHO) Guidelines on Physical Activity, Sedentary Behaviour and Sleep for Children under 5 Years of Age were released in 2019. The aim of this study was to examine the proportion of Chinese kindergarten children who met each individual guideline and each combination of the guidelines and the associations with adiposity. Methods Participants were 254 kindergarten children aged 4.1–6.3 years recruited from three kindergartens in urban area of Beijing. Physical activity, sedentary behaviour and sleep duration were assessed using 24-h accelerometry over three consecutive days. Screen time was reported by parents. Weight and height were measured; and children were categorised into normal weight and overweight/obese groups according to the WHO age- and sex- specific criteria. Frequency analyses were performed to examine the proportion of children meeting individual and combination of these guidelines. Logistics regression analyses were conducted to examine the associations between guideline compliance and adiposity. Results The proportion of children who met the physical activity (≥ 3 h daily physical activity, including ≥1 h daily moderate- to vigorous-intensity physical activity (MVPA)), sedentary screen time (< 1 h/day), and sleep guidelines (10-13 h/day) were 65.4, 88.2 and 29.5%, respectively; only 15.0% met all three guidelines and 2.7% did not meet any of the guidelines. Not meeting the physical activity guideline, sleep guideline, or combination of any two guidelines, or all three guidelines was not associated with overweight or obesity; however, children who did not meet the sedentary screen time guidelines were at higher risk for overweight and obesity (odds ratio = 3.76, 95% CI: 1.50–9.45). Conclusions In our study, only a small proportion of children met all three guidelines. Most Chinese kindergarten children met physical activity guidelines or screen time guidelines, whereas fewer children met sleep guideline. Not meeting sedentary screen time guidelines was associated with adiposity, which warrant further interventions for limiting screen time in young children.

BMC Public Health 2020; 20:122. [PMID: 31996192 PMCID: PMC6988217 DOI: 10.1186/s12889-020-8232-9] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/12/2019] [Accepted: 01/16/2020] [Indexed: 12/02/2022] Open
Abstract
Background Many young people form unhealthy behavioural habits, such as low intake of fruit and vegetables, high intake of energy-dense snack foods, and excessive sedentary screen-based behaviours. However, there is a shortage of parent-and home-focused interventions to change multiple health behaviours in children. Methods Kids FIRST was a 12-week, home- and school-based pilot randomised controlled trial to reduce screen-time and unhealthy snacking with assessments at pre- (baseline) and post-intervention. Four UK schools were randomised to control or one of three interventions targeting reductions in (1) screen-time and unhealthy snacking (ST + Sn), (2) screen-time (ST only), (3) unhealthy snacking (Sn only), and parents with children aged 9–11 years were recruited via schools. Intervention group parents received four online ‘sessions’ and four packages of resources tailored to each group. Children received four 30-min lessons during school time. Children and parents reported their own screen-time behaviours, children reported their own snacking behaviours. Descriptive analyses were undertaken using principles of intention to treat. Results Initial feasibility was shown in that this study successfully recruited schools and families into all four study arms and retained them over a period of 13 weeks (retention rate ≥ 74%). Seventy-five children and 64 parents provided full baseline questionnaire data. Reductions in children’s school day and weekend day TV/DVD viewing and computer game use were found in the ST + Sn and ST groups, while self-reported smartphone use increased in these groups. Similar results were found for parents’ TV/DVD, computer and smartphone use in these groups. Little to no changes were found in reports of the dietary variables assessed in any intervention group for children or parents. Conclusions These preliminary findings show some promise for the Kids FIRST intervention. Based on these findings, a future full trial should recruit a more diverse sample of families and optimise the intervention and intervention resources to more fully engage parents with the dietary-based components of the intervention programme, where fewer changes were seen. Although most parents reporting receiving the intervention resources, further development work is required to achieve higher levels of engagement. This might include greater parent and child engagement work early in the development of the project. Trial registration Retrospectively registered in June 21st 2019 with ClinicalTrials.gov (number NCT03993652).

Int J Obes (Lond) 2019; 44:790-802. [PMID: 31827254 DOI: 10.1038/s41366-019-0502-1] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/21/2019] [Revised: 11/06/2019] [Accepted: 11/17/2019] [Indexed: 12/20/2022]
Abstract
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.

Abstract
INTRODUCTION In Spain, one third of all children and two-thirds of adults suffer from excess weight, a condition that generates a direct excess medical cost of 2000 million Euros. Obesogenic food environments cause obesity by promoting the consumption of sugar-sweetened beverages and ultra-processed foods. Accordingly, we propose five priority policies capable of reversing the epidemic of obesity and related non-communicable diseases through the creation of healthy food environments. THE POWER (PODER IN SPANISH) OF FOOD POLICIES Advertising (Publicidad): regulation of unhealthy food and drink advertisements carried by all media and targeted at children, and prohibition of sponsorships of congresses, conferences or sports events and endorsements by scientific associations or health professionals. Supply (Oferta): promotion of a 100% healthy supply of goods on sale in vending machines sited at educational, health and sports centres. Demand (Demanda): levying a tax of at least 20% on sugar-sweetened beverages, accompanied by subsidies or reduced taxes on healthy foods and availability of drinking water free of charge at all public venues and areas. Labelling (Etiquetado): effective application of the Nutri-Score through the use of incentives, regulation and public-tender mechanisms. Reformulation (Reformulación): revising and redrawing reformulation agreements with the industry, setting more ambitious goals and mandatory compliance. A FINAL THOUGHT These five proposed interventions, all of which have been successfully applied in other countries, will serve to raise population awareness and have a positive impact on health and the economy, through reducing the health care costs of obesity and enhancing work productivity. These measures should form part of a wide-ranging transformation of the food system, with agri-food policies that foster the sustainable production of healthy foods.

Abstract
Food and beverage cues (visual displays of food or beverage products/brands) featured in traditional broadcast and digital marketing are predominantly for products high in fat, sugar and/or salt (HFSS). YouTube is hugely popular with children, and cues featured in content uploaded by YouTube video bloggers (influencers) has been shown to affect children’s eating behavior. However, little is known about the prevalence of such cues, the contexts in which they appear, and the frequency with which they are featured as part of explicit marketing campaigns. The objective of this study was to explore the extent and nature of food and beverage cues featured in YouTube videos of influencers popular with children. All videos uploaded by two influencers (one female, one male) over a year (2017) were analyzed. Based on previous content analyses of broadcast marketing, cues were categorized by product type and classified as “healthy” or “less healthy” according to the UK Nutrient Profiling Model. Cues were also coded for branding status, and other factors related to their display (e.g., description). In total, the sample comprised 380 YouTube videos (119.5 h) and, of these, only 27 videos (7.4%) did not feature any food or beverage cues. Cakes (9.4%) and fast foods (8.9%) were the most frequently featured product types, less frequent were healthier products such as fruits (6.5%) and vegetables (5.8%). Overall, cues were more frequently classified as less healthy (49.4%) than healthy (34.5%) and were presented in different contexts according to nutritional profile. Less healthy foods (compared with healthy foods) were more often; branded, presented in the context of eating out, described positively, not consumed, and featured as part of an explicit marketing campaign. These data provide the first empirical assessment of the extent and nature of food and beverage cue presentation in YouTube videos by influencers popular with children. Given the emerging evidence of the effects of influencer marketing of food and beverages on children’s eating behavior, this exploratory study offers a novel methodological platform for digital food marketing assessment and delivers important contextual information that could inform policy deliberations in this area.

Abstract
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.
