INFORMAS (International Network for Food and Obesity/non-communicable diseases Research, Monitoring and Action Support): overview and key principles

Food and nutrition security definitions, constructs, frameworks, measurements, and applications: global lessons

Food security (FS) is a powerful social determinant of health (SDOH) and is crucial for human and planetary health. The objectives of this article are to (i) provide clarity on the definitions of FS and nutrition security; (ii) provide a framework that clearly explains the links between the two constructs; (iii) summarize measurement approaches, and (iv) illustrate applications to monitoring and surveillance, policy and program design and evaluation, and research, mainly based on the ongoing rich experience with food insecurity (FI) scales. A clear and concise definition of FI and corresponding frameworks are available. There are different methods for directly or indirectly assessing FI. The best method(s) of choice need to be selected based on the questions asked, resources, and time frames available. Experience-based FI measures disseminated from the United States to the rest of the world in the early 2000s became a game changer for advancing FI research, policy, program evaluation, and governance. The success with experience FI scales is informing the dissemination, adaptation, and validation of water insecurity scales globally. The many lessons learned across countries on how to advance policy and program design and evaluation through improved FS conceptualization and measurement should be systematically shared through networks of researchers and practitioners.

Perspective: Mexico's Experience in Building a Toolkit for Obesity and Noncommunicable Diseases Prevention

Noncommunicable diseases (NCDs) are a leading cause of death and disability worldwide, with a higher risk of death in low- and middle-income countries. Diet and excess weight are risk factors for NCDs. In Mexico, the prevalence of overweight and obesity increased dramatically in the last 30 y and is among the highest in the world. To address this public health problem, governments and public health professionals have several policy instruments available. In this study, we present the policy instruments currently approved in Mexico, which include fiscal, informational, and authoritative tools that aim to improve the food environment and promote healthy behaviors (taxes, school food guidelines, front-of-pack labeling, marketing regulations, and dietary guidelines). These types of interventions are important in regions like Latin America, where social inequities and poor access to information are common, and individual healthy choices are often limited. These interventions target the environments in which individuals live, study, work, and seek entertainment, while limiting access to unhealthy choices and offering information to promote healthy alternatives. The Mexican experience in design, implementation, and evaluation of policies to improve the food environment can be useful for other low- and middle-income countries facing similar challenges.

The potential influence of the digital food retail environment on health: A systematic scoping review of the literature

INTRODUCTION

The digital food retail environment (defined in this study as a digital platform, app or website where food can be purchased by individuals for personal consumption) is an emerging component of the wider food system. We aimed to systematically search and review the literature to understand the potential influence of the digital food retail environment on population diets and health.

METHODS

Four databases (across health, business, and marketing) and grey literature were searched using terms relating to "food and beverages," "digital," and "purchasing." Identified studies were included if they examined any aspect of the digital food retail environment where outcomes were examined with a health-related focus and were published before September 2023. All study designs were included (quantitative, qualitative, observational, and experimental). Reviews and conference abstracts were excluded.

RESULTS

We identified 21,382 studies, of which 57 articles were eligible for inclusion. Of the 57 included studies, 30 studies examined online grocery retail, 22 examined online food delivery platforms, and five examined meal kit subscription services. Of the 30 studies examining online grocery retail, six studies reported that customers believed they purchased fewer unhealthy food and beverages when shopping online, compared with shopping in-store. Nevertheless, customers also reported that their ability to choose healthy foods and beverages was reduced when shopping online due to difficulty in product comparison. Studies that examined online food delivery platforms primarily found that they promoted unhealthy foods and beverages more often than healthy options, through extensive use of marketing practices such as price discounts and images, and that unhealthy food offerings on these platforms dominate. Meal kit subscription services offered mostly healthy meals, with studies suggesting that these types of services may help individuals alleviate some of their "mental load" and stress related to cooking meals for their families.

CONCLUSIONS

The literature describing the digital food retail environment was found to be diverse, with different aspects having potential to impact health in different ways. Some evidence suggests that online grocery retail and meal kit subscription services may have positive population dietary impacts, whereas online food delivery platforms appear likely to promote unhealthy food purchasing. However, the current evidence base is fragmented, with many knowledge gaps. Further research is required to understand the influence of the digital food retail environment on population diets and how these environments can be designed to support healthy food choices.

Understanding the Food Environment and Its Impact on Diet and Health in Asia: A Scoping Review

Food environment (FE), an interface where people interact with a broader food system, is critical to health. Understanding the Asian FE may help to tackle the "triple burden of malnutrition" through informed research and policy. This review identifies FE domains assessed in the Asian context and collates the tools/measures used in these evaluations. We further synthesized the reported associations of FE with diet and health outcomes and identified knowledge gaps. Forty-two articles were reviewed (East Asia, n = 25, 60%; South Asia, n = 8, 19%; and Southeast Asia, n = 9, 21%). The results showed that FE was frequently examined in children, adolescents, or adults, but data were scarce in older adults. Food availability (n = 30) and accessibility (n = 19) were popularly studied domains. Furthermore, FE was measured using geographic information systems (n = 18), market (n = 7), or stakeholder (n = 21) surveys. Twenty-eight (67%) articles assessed associations of FE exposures with diet (n = 12) and health (n = 21). Increased food availability and accessibility were associated with poorer dietary and health outcomes despite nonexisting validity and reliability reporting in 62% of articles. Limited high-quality studies emphasize the need for harmonized definitions, better study designs, and validated FE measures/tools in Asia. Improving the quality of FE research is critical to designing effective interventions to improve public health nutrition in Asia.

Centering context when characterizing food environments: the potential of participatory mapping to inform food environment research

Food environments are a critical place within the food system to implement interventions aimed at enabling sustainable diets. In this perspective article, we argue for the need for food environment research to more comprehensively examine the different types of food environments that people access within their communities to ensure that interventions and programs are better aligned with people's lived experiences. We highlight the potential ways in which participatory mapping (PM) can be leveraged to better design food environment research by: (1) identifying the different food environment types that are accessed within a given community; (2) providing insight into the timing for data collection; (3) informing the prioritization of where to conduct food environment assessments; and (4) highlighting the dynamism of food environments over time (e.g., across a given day or across seasons). We provide a case study example of the application of PM and the lessons learned from it in Cambodia. By conceptualizing food environments in a more comprehensive way, from the perspective of the people living within a given community, we will be able to measure food environments in a way that more closely aligns with people's lived experiences.

Food environment research in Canada: a rapid review of methodologies and measures deployed between 2010 and 2021

Numerous research methodologies have been used to examine food environments. Existing reviews synthesizing food environment measures have examined a limited number of domains or settings and none have specifically targeted Canada. This rapid review aimed to 1) map research methodologies and measures that have been used to assess food environments; 2) examine what food environment dimensions and equity related-factors have been assessed; and 3) identify research gaps and priorities to guide future research. A systematic search of primary articles evaluating the Canadian food environment in a real-world setting was conducted. Publications in English or French published in peer-reviewed journals between January 1 2010 and June 17 2021 and indexed in Web of Science, CAB Abstracts and Ovid MEDLINE were considered. The search strategy adapted an internationally-adopted food environment monitoring framework covering 7 domains (Food Marketing; Labelling; Prices; Provision; Composition; Retail; and Trade and Investment). The final sample included 220 articles. Overall, Trade and Investment (1%, n = 2), Labelling (7%, n = 15) and, to a lesser extent, Prices (14%, n = 30) were the least studied domains in Canada. Among Provision articles, healthcare (2%, n = 1) settings were underrepresented compared to school (67%, n = 28) and recreation and sport (24%, n = 10) settings, as was the food service industry (14%, n = 6) compared to grocery stores (86%, n = 36) in the Composition domain. The study identified a vast selection of measures employed in Canada overall and within single domains. Equity-related factors were only examined in half of articles (n = 108), mostly related to Retail (n = 81). A number of gaps remain that prevent a holistic and systems-level analysis of food environments in Canada. As Canada continues to implement policies to improve the quality of food environments in order to improve dietary patterns, targeted research to address identified gaps and harmonize methods across studies will help evaluate policy impact over time.

Instruments and indicators for assessing organisational food environments: a scoping review protocol

INTRODUCTION

Many studies have explored the food environment to characterise it and understand its role in food practices. Assessment of the organisational food environment can contribute to the development of more effective interventions to promote adequate and healthy eating. However, few instruments and indicators have been developed and validated for assessing this type of setting. The systematisation of those can be useful to support the planning of future assessments and the development of wide-ranging instruments. This study aims to conduct a scoping review to systematise evidence on instruments and indicators for assessing organisational food environments.

METHODS AND ANALYSIS

This scoping review was planned according to the methodological framework for scoping reviews proposed by Arksey and O'Malley and subsequently enhanced by Levac et al. For the report of the review, the Preferred Reporting Items for Systematic Reviews and Meta-Analyses-Extension for Scoping Reviews (PRISMA-ScR) checklist and guidelines will be used. The search will be conducted using PubMed, Embase, Web of Science, PsycINFO, Scopus and Google Scholar databases. The studies to be included were required to have been published in peer-reviewed journals since January 2005. No geographical, population or language restrictions will be applied given the desired breadth of the review. Two researchers will select the articles and extract the data independently. The conceptual model proposed by Castro and Canella will guide the data extraction and analysis. The results will be presented with narrative synthesis for the extracted data accompanying the tabulated and charted results.

ETHICS AND DISSEMINATION

This study is based on the analysis of published scientific literature and did not involve patients, medical research, or any type of personal information; therefore, no ethical approval was obtained for this study. The results of this scoping review will be submitted for publication in an international peer-reviewed journal, preferably open access.

Examining gender differences in adolescent exposure to food and beverage marketing through go-along interviews

This study explores how adolescents engage with unhealthy food and beverage marketing in online settings, from a gender perspective. Employing an online ethnography approach and using go-along interviews, we explored the experiences of adolescent boys and girls aged 13-17 as they navigated their online experiences with digital food and beverage marketing. Notable themes emerged, including the identification of predatory actions by food companies, the role of protective factors such as family, and the influence of social media influencers in shaping adolescent dietary preferences. Importantly, this research unearthed gender disparities in the participants' responses. Girls, in particular, exhibited a heightened awareness of the protective role played by their families, emphasized the influence of color in marketing strategies, recognized the significance of gender in marketing, and reported exposure to alcohol advertisements-findings that boys less frequently echoed. The study underscores the importance of adolescence as a critical phase in development, during which food companies target these impressionable individuals, driven by their independence and potential for brand loyalty. Moreover, it highlights the potential avenue of gender-specific marketing, offering valuable insights into the gendered dimensions of adolescents' food marketing experiences. By examining the interplay between digital food marketing and gender, this research addresses a critical gap in the literature, shedding light on how gender influences adolescents' perceptions, responses, and behaviors in the context of food marketing strategies. These findings have the potential to inform adolescents of the marketing techniques that target them and guide policymakers in developing and implementing evidence-based regulations aimed at safeguarding adolescents from exposure to unhealthy food marketing.

Consumer nutrition environment measurements for nutrient-dense food availability and food sustainability: a scoping review

Consumer nutrition environments are defined as places in which consumers interact with the food they eat; these food choices can impact human and planetary health. Assessment measures for consumer nutrition environments are numerous, and vary widely on what, and how, they assess the food environment. The objective of this scoping review was to synthesize existing evidence on nutrition environment measurements and their capacity to assess nutrient-dense food access and food sustainability capacity. Eligibility criteria were developed to capture relevant peer-reviewed literature about auditing measures designed to assess nutrient-dense foods and food sustainability capacity in the consumer nutrition environment. A search strategy was conducted to collect articles published between January 1, 2002-June 4, 2022, using PubMed, Web of Science, Scopus, PsycINFO and the Cochrane library electronic databases. After screening 2457 manuscripts, 58 met inclusion criteria. Study aims, funding source(s), types of retailers assessed, assessment format and name, constructs measured, food categories measured, assessment of validity and/or reliability, and other relevant data were extracted from each manuscript. Results showed that most measures use checklists, surveys, questionnaires or similar methods to assess availability, quality, and price of select food items as assessment constructs. Most do not assess nutrient-dense food availability, and even fewer assess food sustainability. Development of comprehensive, reliable, and valid consumer nutrition environment measures that assess nutrient-dense food availability and food sustainability is important for research, planning, evaluation and advocacy aimed at improving consumer food environments for human and planetary health.

Pandemic-associated food insecurity in northern, coastal Ecuador

The COVID-19 pandemic worsened food insecurity worldwide. The aim of this study was to examine the impact of the pandemic on perceived food insecurity among households in rural Esmeraldas, Ecuador. We conducted a cross-sectional survey to characterize pandemic impacts on household livelihoods and food insecurity in five communities. Fifteen months after the pandemic began, food insecurity was reported in almost half of all households. Residents of the least-accessible community reported the greatest disruptions in food availability, while residents of more accessible communities reported greater disruption to livelihoods. These data suggests that transportation restrictions differentially impacted the least accessible rural communities.

Characterizing food environments of hospitals and long-term care facilities in the Netherlands: a mixed methods approach

BACKGROUND

Hospitals and long-term care facilities, which are key institutions to serve health and well-being, have an important exemplary role in providing supportive food environments to encourage healthy and sustainable food choices. The objective of this study is to characterize the physical, socio-cultural, political and economic dimensions of the food environment for health care receivers, health workforce and visitors in healthcare settings, and make comparisons between the food environment of hospitals and long-term care facilities.

METHODS

To characterize the food environment in healthcare settings, two sub-studies were conducted. In sub-study 1, semi-structured interviews were held with staff members (n = 46) representing 11 hospitals and 26 long-term care facilities (rehabilitation centres, nursing homes, institutions for people with intellectual disabilities and mental healthcare institutions). In sub-study 2, staff members audited the food environment in hospitals (n = 28) and long-term care facilities (n = 36) using a predefined checklist.

RESULTS

The food environment in Dutch healthcare settings varies substantially between locations although noticeable differences between hospitals and long-term care facilities were identified. Hospitals and larger long-term care facilities featured more often restaurants and utilized central spaces for preparation of meals, while smaller long-term care facilities often operated as household-like settings. Type of healthcare shaped the socio-cultural food environment, with hospitals primarily emphasizing nutrition for fast recovery, while long-term care facilities more often as an instrument (i.e., to structure the day). Participants highlighted the importance of food policies and broad organizational support for realizing and regulating improvement of the food environment. Yet, long-term care facilities were less familiar with national guidelines for food environments compared to hospitals. Several economical aspects, like profit motives, strict budgets and contracts with external parties affected and shaped the food available within all healthcare settings.

CONCLUSIONS

This study characterized the food environment in Dutch healthcare settings. Disclosed differences between hospitals and long-term care facilities should be incorporated in strategies for a transition of the food environment. Future research should investigate the underlying mechanisms of the healthcare food environment attaining all healthcare stakeholders - health care receivers, staff and visitors - while prioritizing sustainability alongside healthiness.

Validity and reliability of the Perceived Nutrition Environment Measures Survey (NEMS-P) for use in Brazil

OBJECTIVE

The aim of this study is to evaluate the validity and reliability of the Perceived Nutrition Environment Measures Survey (NEMS-P) translated and adapted for use in Brazil.

DESIGN

Validation of the NEMS-P questionnaire. The questionnaires were applied to assess validity and reliability, based on exploratory factor analysis, Cronbach's α coefficient and intra-class correlation, with a significance level of 95 %.

SETTING

Brazil.

PARTICIPANTS

Adults over 20 years of age diagnosed with hypertension were included in the internal validity and reliability test (n 176) and intra-rater reliability (subsample n 35).

RESULTS

Factor analysis obtained satisfactory results. Internal consistency was acceptable for most items, with Cronbach's α ranging from 0·6 to 0·9. The intra-rater reliability of the subsample was also valid, with intra-class correlation coefficient values ranging from 0·5 to 0·9.

CONCLUSION

This work reveals the usefulness of the instrument to assess the perceived food environment in the Brazilian context, being able to measure what is proposed according to its theoretical model, and reproduces the values when applied to a sample different from its original validation. However, refinement of some questions is suggested. Finally, it demonstrates the possibility of using the entire instrument or each section independently, according to the food environments to be investigated.

A comparative analysis of nutrition-related assessment criteria and associated nutrition performance scores of food companies across three prominent corporate sustainability assessment tools

OBJECTIVE

Corporate sustainability assessment tools are increasingly used to evaluate company performance on environmental, social and governance (ESG) criteria. Given the growing burden of diet-related disease and nutrition-related business risks, it is important to understand the scope of nutrition-related ESG data currently available. This study aimed to compare the nutrition-related assessment criteria and associated food company performance across three prominent assessment tools.

DESIGN

Key attributes and assessment criteria of two civil society-led and one commercially available corporate sustainability assessment tools were extracted and compared for the year 2021. Company performance scores for twenty-five major food and beverage manufacturers using these three tools were analysed by nutrition domain: 'Product Portfolio', 'Labelling', 'Marketing', 'Accessibility and Affordability', 'Governance and Reporting', 'Stakeholder Engagement' and 'Employee Health'. To enable comparison between tools, company performance scores were assigned to categories of low (score = 0-25 % score or D), moderately low (25-50 % or C), moderately high (50-75 % or B) and high (75-100 % or A).

SETTING

Global.

PARTICIPANTS

N/A.

RESULTS

The tools covered similar nutrition domains; however, there was heterogeneity in the assessment criteria used to evaluate each domain. When applied to assess the performance of twenty-five major food and beverage manufacturers, a median nutrition-related performance score of moderately low or low was observed across all tools. The highest scoring domain was 'Governance and Reporting', and the lowest scoring domains were 'Product Portfolio' and 'Accessibility and Affordability'.

CONCLUSIONS

Greater standardisation of the nutrition-related criteria against which food companies are assessed is needed as part of efforts to drive improvements in food company practices.

Revolutionising food advertising monitoring: a machine learning-based method for automated classification of food videos

OBJECTIVE

Food advertising is an important determinant of unhealthy eating. However, analysing a large number of advertisements (ads) to distinguish between food and non-food content is a challenging task. This study aims to develop a machine learning-based method to automatically identify and classify food and non-food ad videos.

DESIGN

Methodological study to develop an algorithm model that prioritises both accuracy and efficiency in monitoring and classifying advertising videos.

SETTING

From a collection of Brazilian television (TV) ads data, we created a database and split it into three sub-databases (i.e. training, validation and test) by extracting frames from ads. Subsequently, the training database was classified using the EfficientNet neural network. The best models and data-balancing strategies were investigated using the validation database. Finally, the test database was used to apply the best model and strategy, and results were verified with field experts.

PARTICIPANTS

The study used 2124 recorded Brazilian TV programming hours from 2018 to 2020. It included 703 food ads and over 20 000 non-food ads, following the protocol developed by the INFORMAS network for monitoring food marketing on TV.

RESULTS

The results showed that the EfficientNet neural network associated with the balanced batches strategy achieved an overall accuracy of 90·5 % on the test database, which represents a reduction of 99·9 % of the time spent on identifying and classifying ads.

CONCLUSIONS

The method studied represents a promising approach for differentiating food and non-food-related video within monitoring food marketing, which has significant practical implications for researchers, public health policymakers, and regulatory bodies.

The development of a method for the global health community to assess the proportion of food and beverage companies' sales that are derived from unhealthy foods

CONTEXT

Corporate engagement with food and beverage companies who produce food associated with health harms is a divisive topic in the global nutrition community, with high-profile cases of conflict of interest increasingly coming under scrutiny. There is a need for an agreed method to support health organizations in deciding whether and how to engage with large food and beverage manufacturers.

AIM

The aim of this study was to develop a method to quantify the proportion of sales from food and beverage companies that are derived from unhealthy foods to support organizations in determining which companies might be considered high-risk for engagement.

METHODS

The 2015 WHO Euro nutrient profile model was applied to 35,550 products from 1294 brands manufactured by the top 20 global food and beverage companies from seven countries (Australia, Brazil, China, India, South Africa, UK and USA). For the purpose of this study, products that met the WHO Euro criteria were classified as "healthier" and those that failed were classified as "unhealthy". Products were grouped by brand and weighted by the brand's value sales for 2020. The primary outcome was the proportion of each company's sales that were classified as unhealthy and healthier by company and category.

RESULTS

Overall, 89% of the top 20 companies' brand sales were classified as unhealthy. For every USD$10 spent on the top 20 companies' brands, only $1.10 was spent on products considered healthier. All companies saw the majority of their sales come from unhealthy foods, including soft drinks, confectionery and snacks. None of Red Bull or Ferrero's sales were classified as healthier and less than 5% of total sales were healthier for Mondelēz, Mars, and PepsiCo. Some companies had higher proportions of sales deriving from healthier products, including Grupo Bimbo (48%), Danone (34%) and Conagra (32%), although the majority of their sales were still derived from unhealthy foods.

DISCUSSION

The results presented in this study highlight the reliance the leading food and beverage companies have on sales of unhealthy products that are contributing to diet-related disease globally. The method and steps we have laid out here could be used by organizations in the global health community to identify companies that have conflicts of interest when it comes to engaging with governments, international organizations and public health bodies on issues of policy and regulation.

A Scoping Review of Studies Evaluating the Healthiness of Street Food Vendors

PURPOSE OF REVIEW

This scoping review investigates the available tools for monitoring the healthiness of the food sold at street food outlets globally.

RECENT FINDINGS

Several tools were identified that have been used to evaluate the healthiness of street food outlets; however, these tools are not applicable globally, do not provide simple measures for evaluating the healthiness of foods sold, and generally have not been used across more than one study. The development of a comprehensive tool for measuring the healthiness of the street food environment that can be used across different jurisdictions and with different levels of resourcing is essential in order to understand the current street food environment and how it changes over time. As a major source of food in low- and middle-income countries globally, the street food environment is important to understand in order to know how it might help address the growing burden of diet-related diseases.

Upstream Determinants of Overweight and Obesity in Europe

PURPOSE OF REVIEW

To review the upstream determinants of overweight and obesity in Europe, including food and built environments, and political, commercial, and socioeconomic determinants.

RECENT FINDINGS

Overweight and obesity affect 60% of European adults, and one in three children, and are more common in individuals with low compared to high socioeconomic position (SEP). Individuals in low SEP groups are more exposed to unhealthy built and food environments, including higher exposure to unhealthy food marketing. Industries influencing the food system have much economic power, resulting in ignoring or silencing the role of ultra-processed foods and commercial practices in weight gain. Overall, effective policies to address overweight and obesity have been insufficiently implemented by governments. To accelerate implementation, strengthened political commitment is essential. Policies must also focus on the upstream, structural, and systemic drivers of overweight and obesity; be comprehensive; and target socioeconomic inequalities in diets and physical activity.

Spatio-temporal patterns of the mortality of diseases associated with malnutrition and their relationship with food establishments in Mexico

This study explores the spatio-temporal behavior of mortality due to multiple causes associated with several diseases and their relationship with the physical availability of food. We analyze data for the 2010-2020 period at the municipality level in Mexico. After collecting and standardizing national databases for each disease, we perform SATSCAN temporal and FleXScan spatial cluster analyses. We use the he Kruskal-Wallis test to analyze the differences between municipalities with high relative risk of mortality and their relationship with food retail units and food establishments. We found statistically significant relationships between clusters by disease and the physical availability of food per hundred thousand inhabitants. The main pattern is a higher average density of convenience stores, supermarkets, fast food chains and franchises, and Mexican snack restaurants in high-risk municipalities, while a higher density of grocery stores and inns, cheap kitchens, and menu restaurants exists in the municipalities with low risk. The density of convenience stores, fast food chains and franchises, and Mexican snack restaurants plays a very important role in mortality behavior, so measures must exist to regulate them and encourage and protect convenience stores, grocery stores, and local food preparation units.

Food in my life: How Australian adolescents perceive and experience their foodscape

Food choice has long been recognized as an interaction between psychological, social, cultural, economic, and biological forces through life course events and experiences. Adolescence is a particularly sensitive life stage during which personal and external environments influence food decisions and attitudes that can have long-term implications. Young people represent future households, yet little is understood about their perspectives on, and experiences of, their foodscape. To address this, a photovoice study with thirty-two students was undertaken at three state high schools with differing foodscapes in South East Queensland (Australia). Adolescent perspectives on foodscapes highlighted the food in front of them (either common or favourite foods), food routines, their emotional relationship with food, and the important role that family has in shaping their relationship with food (in particular mothers). Adolescents demonstrated an astute awareness of healthy/good and unhealthy/bad foods in relation to ingredients, ways of eating and different types of foods. Yet they expressed noticeable confusion on this matter, referring to some foods as "healthy-ish", or describing a "balanced" diet as consuming something healthy followed by something unhealthy. We found that adolescents are inundated by discretionary foods on a daily basis, however, are not particularly cognisant of them. These findings have direct implications for preventative health messages targeting adolescents.

Tools developed in Brazil for the promotion and assessment of adequate and healthy eating habits: A scoping review

The objective of this study was to identify and discuss the tools for the promotion and evaluation of adequate and healthy eating based on the Food Guide for the Brazilian Population. The scoping review was conducted according to the JBI Manual for Evidence Synthesis via the Preferred Reporting Items for Systematic reviews and Meta-Analyses extension for Scoping Reviews (PRISMA-ScR) checklist and by searching PubMed/MEDLINE, EMBASE, SciELO and LILACS. Sixteen studies on relevant tools, based on the food guide for individuals of all age groups, were thus included: two descriptive studies, two randomized clinical trial protocols, eleven methodological analyses, and one psychometric paper, aimed at either a focal population (n=12) or health professionals (n=4). Six studies addressed tools for promoting adequate and healthy eating, and ten developed tools for evaluating dietary practices or the knowledge and activities of health professionals. This review can therefore assist health professionals in choosing instruments for the implementation and/or dissemination of food guide recommendations, contributing to the promotion of adequate and healthy eating habits.

Scientific research on food environments in Brazil: a scoping review

OBJECTIVE

To map the scientific research on food environments in Brazil, based on the following questions: How many studies have addressed food environments?; What study designs and methodological approaches were applied?; What is the geographic scope of the studies?; What scenarios and dimensions of food environments were studied?; Which population groups were studied?; How were food environments conceptualised?; What are the main limitations of the studies?

DESIGN

Scoping review conducted in four databases, from January 2005 to December 2022, using different food environment-related terms to cover the main types and dimensions proposed in the literature. The studies were independently selected by two authors. A narrative synthesis was used to summarise the findings.

SETTING

Brazil.

PARTICIPANTS

130 articles.

RESULTS

Scientific research on Brazilian food environments has been increasing. The analytical quantitative approach and the cross-sectional design were the most frequently used. Most articles were published in English. The majority of studies evaluated the community food environment, addressed aspects of the physical dimension, sampled the adult population, had food consumption as an outcome, used primary data, and were carried out in capital cities in the Southeast region. Furthermore, in most articles, no conceptual model was explicitly adopted.

CONCLUSIONS

Gaps in literature are related to the need for conducting studies in the Brazilian countryside, the support for the formulation of research questions based on conceptual models, the use of valid and reliable instruments to collect primary data, in addition to the need for a greater number of longitudinal, intervention and qualitative studies.

Addressing the marketing and availability of unhealthy food and beverages in and around selected schools in Ghana: a community readiness appraisal

OBJECTIVE

This study assessed stakeholder readiness to address unhealthy food and beverage marketing and availability in/around Public Basic Schools (for children 4-15 years) in Greater Accra Region, the highly urbanised administrative capital of Ghana.

DESIGN

The community readiness model was used to conduct in-depth mixed methods interviews with stakeholders. Using predefined anchored rating statements, quantitative readiness scores ranging from 1 to 9 were generated. Thematic qualitative analysis was undertaken to understand barriers and facilitators that could influence the implementation of interventions.

SETTING

Greater Accra Region, Ghana.

PARTICIPANTS

18 key informants from various school/education/citizen sectors, which together represented the 'school community' of Greater Accra Region.

RESULTS

The mean readiness scores indicated that the 'school community' was at the 'preplanning' stage of readiness (4.44±0.98) to address the marketing and availability of unhealthy food and beverages in and around schools. The mean readiness score for 'leadership' was the highest of all dimensions (5.36±1.60), corresponding to the 'preparation' stage. The lowest scores were found for 'community knowledge of efforts' (3.19±2.45) and 'resources for efforts' (3.64±0.87), both of which were at a 'vague awareness' stage.

CONCLUSIONS

The 'school community' recognised that the marketing and availability of unhealthy food and beverages was a problem. Additionally, current leadership was actively supportive of continuing/improving efforts that create healthier children's food environments. However, actions that aim to increase the 'school community's' knowledge of existing interventions and securing resources to sustain those interventions are needed before introducing readiness appropriate strategies.

The Influence of Grandparents on Children's Dietary Health: A Narrative Review

PURPOSE OF REVIEW

To examine and synthesise recent evidence on the role of grandparents in shaping children's dietary health.

RECENT FINDINGS

The influence of grandparents on children's dietary health was evident across studies. Grandparents frequently provide their grandchildren with meals and snacks, and engage in many of the same feeding practices used by parents. Although grandparents report providing their grandchildren with healthy foods, the provision of treat foods high in sugar or fat was a common finding. This provision led to family conflict, with the indulgent behaviours of grandparents seen by parents as a barrier to healthy eating. Grandparents are exerting significant influence on child dietary health. Efforts are needed to ensure these care providers are considered key stakeholders in the promotion of healthy eating and are targeted in policies and programs addressing children's diets. Research that determines how to best support grandparents to foster healthy behaviours in children is critical.

Change in the food environment and measured adiposity in adulthood in the Christchurch Health and development birth cohort, Aotearoa, New Zealand: A birth cohort study

This study investigated associations between change in the food environment and change in measured body mass index (BMI) and waist circumference (WC) in the Christchurch Health and Development Study (CHDS) birth cohort. Our findings suggest that cohort members who experienced the greatest proportional change towards better access to fast food outlets had the slightly larger increases in BMI and WC. Contrastingly, cohort members who experienced the greatest proportional change towards shorter distance and better access to supermarkets had slightly smaller increases in BMI and WC. Our findings may help explain the changes in BMI and WC at a population level.

Unhealthy food availability, prominence and promotion in a representative sample of supermarkets in Flanders (Belgium): a detailed assessment

INTRODUCTION

The supermarket food environment is a key setting for potential public health interventions. This study assessed food availability, prominence and promotion in a representative sample of supermarkets in Flanders (Belgium).

METHODS

A sample of 55 supermarkets across five chains and 16 Flemish municipalities was selected in 2022, about 64% in the most deprived socioeconomic areas. Healthiness indicators related to food availability (ratio of cumulative linear shelf length for healthy versus unhealthy foods), prominence (proportion of unhealthy foods at check-outs and end-of-aisle endcaps), and promotion (food marketing on food packages) were measured.

RESULTS

Overall, the average ratio of healthy/unhealthy foods in supermarkets in Flanders was 0.36, meaning that for every 10m of shelf length of unhealthy foods there was 3.6m of healthy foods. There was a large variation in ratio's across supermarket chains. Of all foods available, 97.5% were ultra-processed at the check outs, while 72.2% and 58.5% were ultra-processed at the front and back end-of-aisle end-caps, respectively. Confectionery and sweet biscuits were the food categories with on average the highest number of marketing messages on pack per 10m of shelf length.

CONCLUSION

Supermarket in-store food environments in Flanders were found generally unhealthy, with those located in low income areas having unhealthier in-store food environments than supermarkets located in medium and high income areas. Despite commitments of all large supermarket chains in Flanders to promote and create healthier in-store food environments, our findings indicate that currently consumers are incentivized to buy unhealthy rather than healthy food products.

Adult food choices in association with the local retail food environment and food access in resource-poor communities: a scoping review

BACKGROUND

There is a growing body of research on local retail food environments globally in both urban and rural settings. Despite this, little research has been conducted on adult food choices, local retail environments, and healthy food access in resource-poor communities. The purpose of this study is therefore to provide an overview of the evidence on adult food choices (measured as dietary intake) in association with the local retail food environment and food access in resource-poor communities (defined as low-income communities and/or households).

METHODS

We searched nine databases for studies published from July 2005 to March 2022 and identified 2426 records in the primary and updated search. Observational studies, empirical and theoretical studies, focused on adults ≤ 65 years, published in English peer-reviewed journals, examining local retail food environments and food access, were included. Two independent reviewers screened identified articles using the selection criteria and data extraction form. Study characteristics and findings were summarized for all studies and relevant themes summarized for qualitative and mixed methods studies.

RESULTS

A total of 47 studies were included in this review. Most studies were cross sectional (93.6%) and conducted in the United States of America (70%). Nineteen (40.4%) studies assessed the association between food choice outcomes and local retail food environment exposures, and evidence on these associations are inconclusive. Associations of certain food choice outcomes with healthy food retail environments were positive for healthy foods (in 11 studies) and unhealthy foods (in 3 studies). Associations of certain food choice outcomes with unhealthy retail food environment exposures were positive for unhealthy foods in 1 study and negative for healthy foods in 3 studies. In 9 studies, some of the food choice outcomes were not associated with retail food environment exposures. A healthy food store type and lower food prices were found to be major facilitators for healthy food access in resource-poor communities, while cost and transportation were the main barriers.

CONCLUSIONS

More research is needed on the local retail food environment in communities in low- and middle-income countries to develop better interventions to improve food choices and access to healthy foods in resource-poor communities.

Establishing the Minimum Media Time Sample Required to Obtain Reliable Estimates of Children's Digital Media Food Marketing Exposures

Background

The ubiquitous nature of food marketing on digital media likely has a profound effect on children's food preferences and intake. Monitoring children's exposure to digital marketing is necessary to raise awareness of the issue, inform policy development, and evaluate policy implementation and effect.

Objectives

This study aimed to establish whether smaller time samples (less time and/or fewer days captured) would provide robust estimates of children's usual exposures to food marketing.

Methods

Using an existing data set of children's digital marketing exposures, which captured children's total screen use over 3 d, a reliability assessment was performed.

Results

A subsample of 30% of children's usual screen time was found to provide reliable estimates of digital food marketing exposure compared with the full sample (intraclass correlation coefficient: 0.885; Cronbach α: 0.884). There was no difference in the rates of marketing (exposures/h) between weekdays and weekend days.

Conclusions

These findings enable researchers to reduce the time and resource constraints that have previously restricted this type of monitoring research. The reduced media time sample will further lessen participant burden.

Characteristics of food environments that influence food acquisition and diets of women in low- and middle-income countries: a scoping review protocol

OBJECTIVE

This scoping review aims to identify and map characteristics of food environments that influence food acquisition practices and dietary intake of women of reproductive age in low- and middle-income countries.

INTRODUCTION

Due to the disproportionate burden of malnutrition on women of reproductive age in low- and middle-income countries, accelerated progress in improving women's nutrition is required to achieve Sustainable Development Goal 2 "Zero hunger" by 2030. Food environments are increasingly recognized as the key interface between consumers and food systems; however, little is known about the characteristics that influence women's food acquisition and diets in low- and middle-income countries, especially during physiological stages of heightened nutritional requirement, such as pre-conception, pregnancy, and breastfeeding.

INCLUSION CRITERIA

This review will consider quantitative, qualitative, mixed methods, or review studies that report on the influence of food environment characteristics on food acquisition practices and dietary intake of women aged 15 to 49 years in any low- or middle-income country, as defined by the World Bank in 2021.

METHODS

Twenty-one databases across EBSCO, Web of Science Core Collection, and PubMed platforms will be searched. Screening, selection, and data extraction will be performed in duplicate by 2 members of the team, with any discrepancies resolved by group discussion. The patterns of food acquisition and dietary intake in relation to food environment characteristics will be charted, mapped, and summarized in tabular and graphical formats. Findings will inform the refinement of effective food environment conceptual frameworks for this nutritionally vulnerable group.

The global impact of tobacco control policies on smokeless tobacco use: a systematic review

BACKGROUND

Smokeless tobacco, used by more than 300 million people globally, results in substantial morbidity and mortality. For smokeless tobacco control, many countries have adopted policies beyond the WHO Framework Convention on Tobacco Control, which has been instrumental in reducing smoking prevalence. The impact of these policies (within and outside the Framework Convention on Tobacco Control) on smokeless tobacco use remains unclear. We aimed to systematically review policies that are relevant to smokeless tobacco and its context and investigate their impact on smokeless tobacco use.

METHODS

In this systematic review, we searched 11 electronic databases and grey literature between Jan 1, 2005, and Sept 20, 2021, in English and key south Asian languages, to summarise smokeless tobacco policies and their impact. Inclusion criteria were all types of studies on smokeless tobacco users that mentioned any smokeless tobacco relevant policies since 2005, except systematic reviews. Policies issued by organisations or private institutions were excluded as well as studies on e-cigarettes and Electronic Nicotine Delivery System except where harm reduction or switching were evaluated as a tobacco cessation strategy. Two reviewers independently screened articles, and data were extracted after standardisation. Quality of studies was appraised using the Effective Public Health Practice Project's Quality Assessment Tool. Outcomes for impact assessment included smokeless tobacco prevalence, uptake, cessation, and health effects. Due to substantial heterogeneity in the descriptions of policies and outcomes, data were descriptively and narratively synthesised. This systematic review was registered in PROSPERO (CRD42020191946).

FINDINGS

14 317 records were identified, of which 252 eligible studies were included as describing smokeless tobacco policies. 57 countries had policies targeting smokeless tobacco, of which 17 had policies outside the Framework Convention on Tobacco Control for smokeless tobacco (eg, spitting bans). 18 studies evaluated the impact, which were of variable quality (six strong, seven moderate, and five weak) and reported mainly on prevalence of smokeless tobacco use. The body of work evaluating policy initiatives based on the Framework Convention on Tobacco Control found that these initiatives were associated with reductions in smokeless tobacco prevalence of between 4·4% and 30·3% for taxation and 22·2% and 70·9% for multifaceted policies. Two studies evaluating the non-Framework policy of sales bans reported significant reductions in smokeless tobacco sale (6·4%) and use (combined sex 17·6%); one study, however, reported an increased trend in smokeless tobacco use in the youth after a total sales ban, likely due to cross-border smuggling. The one study reporting on cessation found a 13·3% increase in quit attempts in individuals exposed (47·5%) to Framework Convention on Tobacco Control policy: education, communication, training, and public awareness, compared with non-exposed (34·2%).

INTERPRETATION

Many countries have implemented smokeless tobacco control policies, including those that extend beyond the Framework Convention on Tobacco Control. The available evidence suggests that taxation and multifaceted policy initiatives are associated with meaningful reductions in smokeless tobacco use.

Restricting child-directed ads is effective, but adding a time-based ban is better: evaluating a multi-phase regulation to protect children from unhealthy food marketing on television

BACKGROUND

As childhood obesity rates continue to rise, health organizations have called for regulations that protect children from exposure to unhealthy food marketing. In this study, we evaluate the impact of child-based versus time-based restrictions of "high-in" food and beverage advertising in Chile, which first restricted the placement of "high-in" advertisements (ads) in television attracting children and the use of child-directed content in high-in ads and, second, banned high-in ads from 6am-10pm. "High-in" refers to products above regulation-defined thresholds in energy, saturated fats, sugars, and/or sodium. High-in advertising prevalence and children's exposure to high-in advertising are assessed.

METHODS

We analyzed a random stratified sample of advertising from two constructed weeks of television at pre-regulation (2016), after Phase 1 child-based advertising restrictions (2017, 2018), and after the Phase 2 addition of a 6am-10pm high-in advertising ban (2019). High-in ad prevalence in post-regulation years were compared to prior years to assess changes in prevalence. We also analyzed television ratings data for the 4-12 year-old child audience to estimate children's ad exposure.

RESULTS

Compared to pre-regulation, high-in ads decreased after Phase 1 (2017) by 42% across television (41% between 6am-10pm, 44% from 10pm-12am) and 29% in programs attracting children (P < 0.01). High-in ads further decreased after Phase 2, reaching a 64% drop from pre-regulation across television (66% between 6am-10pm, 56% from 10pm-12am) and a 77% drop in programs attracting children (P < 0.01). High-in ads with child-directed ad content also dropped across television in Phase 1 (by 41%) and Phase 2 (by 67%), compared to pre-regulation (P < 0.01). Except for high-in ads from 10pm-12am, decreases in high-in ads between Phase 1 (2018) and Phase 2 were significant (P < 0.01). Children's high-in ad exposure decreased by 57% after Phase 1 and by 73% after Phase 2 (P < 0.001), compared to pre-regulation.

CONCLUSIONS

Chile's regulation most effectively reduced children's exposure to unhealthy food marketing with combined child-based and time-based restrictions. Challenges remain with compliance and limits in the regulation, as high-in ads were not eliminated from television. Yet, having a 6am-10pm ban is clearly critical for maximizing the design and implementation of policies that protect children from unhealthy food marketing.

Evaluation and prioritization of food environment policies in Norway using the Healthy Food Environment Policy Index (Food-EPI)

Background

Government policies promoting healthier food environments can contribute to healthier diets and prevent obesity and diet-related non-communicable diseases.

Objective

To assess the level of implementation of internationally recommended food environment policies in Norway and establish prioritised actions to create healthier food environments.

Design

The Healthy Food Environment Policy Index (Food-EPI) was adapted to the Norwegian context. It comprised 45 good practice indicators of government food environment policy and infrastructure support. Systematically compiled evidence of relevant policies was verified by government officials and formed the basis for assessing the level of implementation of these policies compared against international best practice benchmarks. The assessment was done by a national non-government expert panel (n = 35). The experts thereafter proposed and prioritized policy actions for government implementation.

Results

Most indicators were rated at a medium or high degree of implementation in both the policy action (69%) and the infrastructure support (77%) components. No indicators were rated as having 'none or very little implementation'. Among the 14 recommended policy actions, active use of price regulation to increase the price of unhealthy foods and decrease the price of healthy foods was the highest priority. Other top priorities were ensuring healthy food environments in public settings and introducing free school meals. Demonstrating knowledge-based and coherent political leadership in public health nutrition policies was the highest priority among the 11 recommended infrastructure support actions.

Conclusion

The overall policies in Norway to promote a healthy diet show a medium to high level of implementation. This study highlights that there is still room for additional improvements in Norwegian policies and infrastructure support to promote healthy food environments.

The implementation and effectiveness of outlet-level healthy food and beverage accreditation schemes: A systematic review

Healthy food outlet accreditation schemes represent an avenue for incentivizing food retailers to promote healthy eating patterns by improving the healthiness of food environments. This systematic review aimed to (i) assess the impact of food outlet-level accreditation schemes on outlet practices and customer purchases and (ii) identify barriers and enablers to scheme implementation. Peer-reviewed and grey literature were systematically searched. Eligible studies related to outlet-level food and beverage accreditation schemes across any food retail setting. Findings were narratively synthesized by retailer type according to (i) scheme characteristics (governance, targeted products, support, and monitoring); (ii) scheme outcomes (rate of uptake, proportion of certified retailers, impact on purchasing, customer perspectives, and retailer perspectives); and (iii) barriers and enablers to implementation. From 21,943 records screened, 48 were included, covering 26 schemes. Most (18) targeted restaurants or convenience stores. Average uptake was 65% of all outlets approached to participate. Implementation of accreditation schemes was associated with healthier customer purchases in convenience stores, schools, and hospitals, but evidence from restaurants was mixed. Enablers of scheme implementation included support for implementation and maintenance, flexible scheme criteria, and motivated retail staff. Healthy food outlet accreditation schemes represent a promising mechanism for engaging retailers to improve the healthiness of food retail environments.

Nutritional quality of snacks and beverages sold through vending machines in a large Hispanic-serving urban college campus in the United States: A cross-sectional study

Students from nutritionally-vulnerable neighborhoods face dietary challenges through built environment of college vending machines. In this cross-sectional study, snacks and beverages sold in vending machines for a 4-week period in a Bronx-based Hispanic-serving college were recorded. Nutritional information was recorded from nutrition labels. Proportion of low- and high-sodium foods, "smart snacks" with a limit of 200 kcal and 200 mg of sodium, and foods with added sugar were recorded. Snacks had significantly higher calories and sodium per serving (227 kcal, 208 mg) than beverages (132 kcal, 90 mg) (t-test, p < 0.001). Almost a third of the snacks (32%) qualified as "smart snacks" for calories and 62% qualified as "smart snacks" for sodium. Beverages contained less than half the number of ingredients as snacks. About 53% of beverages and almost 60% of snacks listed sugar among the first five ingredients. Results underscore the need for colleges to promote less-processed entities with less added sugar.

The structure of the Canadian packaged food and non-alcoholic beverage manufacturing and grocery retailing sectors through a public health lens

BACKGROUND

Corporate power has been recognized as an important influence on food environments and population health more broadly. Understanding the structure of national food and beverage markets can provide important insight into the power held by leading corporations. This study aimed to descriptively analyze the structure of the Canadian food and beverage manufacturing and grocery retailing sectors as of 2020/21.

METHODS

Packaged food manufacturers, non-alcoholic beverage manufacturers and grocery retailers with ≥ 1% market share in 2020/21 in Canada as per Euromonitor International were identified and characterized. Proportion of market share held by public vs private, multinational vs national, and foreign multinational companies was assessed for the 3 sectors. The concentration of 14 packaged food, 8 non-alcoholic beverage and 5 grocery retailing markets was assessed using the Herfindahl-Hirschman Index (HHI) and the four firm concentration ratio (CR4) (HHI > 1800 and CR4 > 60 suggest high market concentration). Company ownership structure was also assessed, including common ownership of public companies by three of the largest global asset managers using data from Refinitiv Eikon, a financial market database.

RESULTS

The Canadian non-alcoholic beverage manufacturing sector, and, to a lesser extent, the packaged food manufacturing sector were dominated by foreign multinational companies, in contrast with the grocery retailing sector which was dominated by national companies. Market concentration varied across sectors and markets but was substantially greater within the retailing (median CR4 = 84; median HHI = 2405) and non-alcoholic beverage sectors (median CR4 = 72; median HHI = 1995) compared to the packaged food sector (median CR4 = 51; median HHI = 932). There was considerable evidence of common ownership across sectors. Overall, the Vanguard Group Inc owned at least 1% of shares in 95% of publicly listed companies, Blackrock Institutional Trust Company 71%, and State Street Global Advisors (US) 43%.

CONCLUSIONS

The Canadian packaged food and non-alcoholic beverage manufacturing and grocery retailing sectors include several consolidated markets, with a high degree of common ownership by major investors. Findings suggest that a small number of large corporations, particularly in the retailing sector, have extensive power to influence Canadian food environments; their policies and practices warrant substantial attention as part of efforts to improve population diets in Canada.

National Public Health Surveillance of Corporations in Key Unhealthy Commodity Industries - A Scoping Review and Framework Synthesis

BACKGROUND

Corporations in unhealthy commodity industries (UCIs) have growing influence on the health of national populations through practices that lead to increased consumption of unhealthy products. The use of government-led public health surveillance is best practice to better understand any emerging public health threat. However, there is minimal systematic evidence, generated and monitored by national governments, regarding the scope of UCI corporate practices and their impacts. This study aims to synthesise current frameworks that exist to identify and monitor UCI influence on health to highlight the range of practices deployed by corporations and inform future surveillance efforts in key UCIs.

METHODS

Seven biomedical, business and scientific databases were searched to identify literature focused on corporate practices that impact human health and frameworks for monitoring or assessment of the way UCIs impact health. Content analysis occurred in three phases, involving (1) the identification of framework documents in the literature and extraction of all corporate practices from the frameworks; (2) initial inductive grouping and synthesis followed by deductive synthesis using Lima and Galea's 'vehicles of power' as a heuristic; and (3) scoping for potential indicators linked to each corporate practice and development of an integrated framework.

RESULTS

Fourteen frameworks were identified with 37 individual corporate practices which were coded into five different themes according the Lima and Galea 'Corporate Practices and Health' framework. We proposed a summary framework to inform the public health surveillance of UCIs which outlines key actors, corporate practices and outcomes that should be considered. The proposed framework draws from the health policy triangle framework and synthesises key features of existing frameworks.

CONCLUSION

Systematic monitoring of the practices of UCIs is likely to enable governments to mitigate the negative health impacts of corporate practices. The proposed synthesised framework highlights the range of practices deployed by corporations for public health surveillance at a national government level. We argue there is significant precedent and great need for monitoring of these practices and the operationalisation of a UCI monitoring system should be the object of future research.

Applicability of the Socioecological Model for Understanding and Reducing Consumption of Ultra-Processed Foods in Canada

Ultra-processed foods (UPFs) have become a major contributor to the diets of Canadians, with a recent report from Statistics Canada suggesting Canadians are consuming almost one-half of their calories from UPFs. Research has linked UPF consumption with increased risk for chronic diseases such as cardiovascular disease and type 2 diabetes, among others. This paper sought to investigate the popularity of UPFs, particularly among children and teens, utilizing the socioecological model as a framework to illustrate how influences at multiple levels (i.e., public policy, organizational, community, interpersonal, and individual) have played a role in the proliferation of UPFs. Evidence from previous studies is used to identify how factors at different levels may influence UPF consumption and discuss potential strategies for reducing UPF consumption. To meaningfully reduce UPF consumption among Canadians, all levels should be considered, with the goal of creating a healthier Canadian population.

Translating results into action: the global impact of the World Breastfeeding Trends Initiative

The World Breastfeeding Trends Initiative (WBTi) provides a participative framework to bridge the gaps in policies and programs on breastfeeding. This concurrent mixed-methods study investigated how and why carrying out WBTi evaluations in countries influences their breastfeeding policies and outcomes. We used data from WBTi's Global Repository to evaluate performance scores in 98 countries and conducted semi-structured in-depth interviews to investigate the impact of WBTi process, using the Managing for Development Results structure and actor-network theory. Countries that conducted WBTi multiple times seem to have better breastfeeding policies and practices than countries that have assessed only once. The central feature of the process and its subsequent impact is the dialectical interaction between the technical and political elements of the WBTi exercise. We believe that WBTi's framework is a promising monitoring and evaluation tool that could be used to engage dialogue in other public health areas.

Pilot test of the NOURISHING policy index-Assessing governmental nutrition policies in five European countries

The NOURISHING database is a repository of more than 1000 verified nutrition and diet-related governmental policy actions currently in effect globally. The database is a unique and rich data source on governmental policy actions with a potential for developing tools that capture the overall policy efforts in a country, identify policy gaps, and enable cross-national comparisons. Policy actions from a sample of five European countries have been benchmarked against aspirational standards using the NOURISHING benchmarking tool. This paper presents the results of the pilot testing from the benchmarking process for the construction of the NOURISHING policy index. The development of the index was guided by existing tools for developing composite indicators. The findings from the pilot test indicate that the NOURISHING policy index can identify both policy gaps and cross-national policy differences. These results demonstrate that the policy index merits testing on a larger sample to identify potential refinements.

Transitioning food environments and diets of African migrants: implications for non-communicable diseases

Non-communicable diseases disproportionately affect African migrants from sub-Saharan Africa living in high-income countries (HICs). Evidence suggests this is largely driven by forces that include migration, globalisation of unhealthy lifestyles (poor diet, physical inactivity and smoking), unhealthy food environments, socio-economic status and population ageing. Changes in lifestyle behaviours that accompany migration are exemplified primarily by shifts in dietary behaviours from more traditional diets to a diet that incorporates that of the host culture, which promotes the development of obesity, diabetes, hypertension and CVD. The current paper presents a critical analysis of dietary change and how this is influenced by the food environment and the socio-economic context following migration. We used a food systems framework to structure the discussion of the interaction of factors across the food system that shape food environments and subsequent dietary changes among African migrant populations living in HICs.

Consumer willingness to pay for healthier food products: A systematic review

Food retail strategies to improve the healthiness of food and beverage options may increase purchasing of healthier options and improve diets. Consumer demand for healthier options is an important determinant of the successful implementation and maintenance of healthy food retail interventions. A systematic review of peer-reviewed literature was undertaken to explore whether consumers are willing to pay more for healthier foods and to determine the key factors that influence willingness to pay. Fifteen studies reported the results of 26 experiments providing willingness to pay estimates for healthier food products across a range of food retail environments. Twenty three out of the 26 experiments included in this review (88.5%) found consumers would pay a 5.6% to 91.5% (mean 30.7%) price premium for healthier foods. Studies consistently found a positive willingness to pay for foods with reduced fat and wholegrains with additional fruit and vegetables, while willingness to pay for foods with reduced salt or a combination of low fat and sugar, or salt showed mixed results. Adults over 60 years, females, those living with obesity, and consumers who aim to maintain a healthy lifestyle were more likely to pay a price premium for healthier food, whereas younger consumers, consumers with healthy weight, and consumers with higher levels of education were less likely to pay higher prices. The results of this review contribute to our understanding of consumer preferences for healthier products and provide information to retailers on consumer surplus (benefits) associated with the provision of healthier food alternatives.

School environments and obesity: a systematic review of interventions and policies among school-age students in Latin America and the Caribbean

BACKGROUND

The rapid rise in obesity rates among school children in Latin America and the Caribbean (LAC) could have a direct impact on the region's physical and mental health, disability, and mortality. This review presents the available interventions likely to reduce, mitigate and/or prevent obesity among school children in LAC by modifying the food and built environments within and around schools.

METHODS

Two independent reviewers searched five databases: MEDLINE, Web of Science, Cochrane Library, Scopus and Latin American and Caribbean Health Sciences Literature for peer-reviewed literature published from 1 January 2000 to September 2021; searching and screening prospective studies published in English, Spanish and Portuguese. This was followed by data extraction and quality assessment using the Cochrane risk-of-bias tool (RoB 2) and the Risk of Bias in Non-Randomized Studies of Interventions (ROBINS-I), adopting also the PRISMA 2020 guidelines. Due to the heterogeneity of the intervention's characteristics and obesity-related measurements across studies, a narrative synthesis was conducted.

RESULTS

A total of 1342 research papers were screened, and 9 studies were included; 4 in Mexico, and 1 each in Argentina, Brazil, Chile, Colombia, and Ecuador. Four studies reported strategies for modifying food provision; four other targeted the built environment, (modifying school premises and providing materials for physical activity); a final study included both food and built environment intervention components. Overall, two studies reported that the intervention was significantly associated with a lower increase over time in BMI/obesity in the intervention against the control group. The remaining studies were non-significant.

CONCLUSIONS

Data suggest that school environmental interventions, complementing nutritional and physical education can contribute to reduce incremental childhood obesity trends. However, evidence of the extent to which food and built environment components factor into obesogenic environments, within and around school grounds is inconclusive. Insufficient data hindered any urban/rural comparisons. Further school environmental intervention studies to inform policies for preventing/reducing childhood obesity in LAC are needed.

Retail Food Environment around Schools in Barcelona by Neighborhood Socioeconomic Status: Implications for Local Food Policy

Childhood obesity is a relevant public health problem. The school food environment has been identified as an important factor for promoting healthy eating behaviors. This study assessed the availability of and proximity to unhealthy food stores around schools (n = 22) in the city of Barcelona and its association with neighborhood socioeconomic status (NSES). We conducted this cross-sectional study between 2019 and 2020. First, we identified all food retailers (n = 153) within a 400-m buffer around each school and identified those selling unhealthy food products. Then, we used Poison regression models to measure the association between NSES and the healthy food availability index (HFAI), adjusting for population density and distance. A total of 95% of the food establishments studied were classified as unhealthy (n = 146). In all, 90% of schools that had, at least, two unhealthy retailers in their proximity. There were significant differences in the mean distance to unhealthy establishments according to neighborhood SES and population density (p < 0.05). We found a positive association between schools located in higher SES neighborhoods and a higher availability and affordability of healthy food products (IIR = 1.67, 95% CI = 1.45−1.91 p = 0.000). We found strong social inequalities in the supply of healthy foods in Barcelona. Local food policy interventions addressing retail food environment around schools should consider socioeconomic inequalities.

Unhealthy food and beverage marketing to children on digital platforms in Aotearoa, New Zealand

BACKGROUND

Children's exposure to unhealthy food and beverage marketing has a direct impact on their dietary preference for, and consumption of, unhealthy food and drinks. Most children spend time online, yet marketing restrictions for this medium have had slow uptake globally. A voluntary Children's and Young People's Advertising (CYPA) Code was implemented in Aotearoa, New Zealand (NZ) in 2017. This study explores the Code's limitations in protecting children from harmful food and beverage marketing practices on digital platforms accessible to children.

METHODS

A cross-sectional content analysis of company websites (n = 64), Facebook pages (n = 32), and YouTube channels (n = 15) of the most popular food and beverage brands was conducted between 2019 and 2021 in NZ. Brands were selected based on market share, web traffic analysis and consumer engagement (Facebook page 'Likes' and YouTube page views). Analysis focused on volume and type of food posts/videos, level of consumer interaction, nutritional quality of foods pictured (based on two different nutrient profile models), and use of specific persuasive marketing techniques.

RESULTS

Eighty-one percent of websites (n = 52) featured marketing of unhealthy food and beverages. Thirty-five percent of websites featuring unhealthy food and beverages used promotional strategies positioning their products as 'for kids'; a further 13% used 'family-oriented' messaging. Several websites featuring unhealthy products also had designated sections for children, 'advergaming,' or direct messaging to children. Eighty-five percent of all food and drink company Facebook posts and YouTube videos were classified as unhealthy. Twenty-eight percent of Facebook posts for unhealthy products featured persuasive promotional strategies, and 39% premium offers. Nearly 30% of YouTube videos for unhealthy food and beverages featured promotional strategies, and 13% premium offers. Ten percent of Facebook posts and 13% of YouTube videos of unhealthy food and beverages used marketing techniques specifically targeting children and young people.

CONCLUSIONS

The voluntary CYPA Code has been in effect since 2017, but the inherent limitations and loopholes in the Code mean companies continue to market unhealthy food and beverages in ways that appeal to children even if they have committed to the Code. Comprehensive and mandatory regulation would help protect children from exposure to harmful marketing.

What Opportunities Exist for Making the Food Supply Nutrition Friendly? A Policy Space Analysis in Mexico

BACKGROUND

As part of a global policy response for addressing malnutrition, food system actions have been proposed. Within food system interventions, policies directed to supply chains have the potential to increase the availability and affordability of a healthy diet. This qualitative study aimed to identify opportunities to integrate nutrition as a priority into the food supply policy space in Mexico.

METHODS

Data were collected through analysis of 19 policy documents and 20 semi-structured stakeholder interviews. As an analytical framework, we used policy space analysis and embedded the Advocacy Coalition Framework (ACF) and the steps of the food chain of the conceptual framework of food systems for diets and nutrition.

RESULTS

Policy issues relevant to nutrition were viewed differently in the economic and agricultural sectors versus the health sector. Overall, the main policy objective related to nutrition within the economic and agricultural sectors was to contribute to food security in terms of food quantity. Nutrition was an objective in itself only in the health sector, with a focus on food quality. Our policy space analysis reveals an opportunity to promote a new integrated vision with the recent creation of an intersectoral group working on the public agenda for a food system transformation. This newer integrative narrative on food systems presents an opportunity to shift the existing food security narrative from quantity towards considerations of diet quality.

CONCLUSION

The political context and public agenda are favorable to pursue a food system transformation to deliver sustainable healthy diets. Mexico can provide a case study for other low- and middle-income countries (LMICs) for putting nutrition at the center of food policy, despite the ongoing constraints on achieving this.

Policy implementation and priorities to create healthy food environments using the Healthy Food Environment Policy Index (Food-EPI): A pooled level analysis across eleven European countries

Background

Food environments have been recognised as highly influential on population diets. Government policies have great potential to create healthy food environments to promote healthy diets. This study aimed to evaluate food environment policy implementation in European countries and identify priority actions for governments to create healthy food environments.

Methods

The Healthy Food Environment Policy Index (Food-EPI) was used to evaluate the level of food environment policy and infrastructure support implementation in Estonia, Finland, Germany, Ireland, Italy, the Netherlands, Norway, Poland, Portugal, Slovenia, and Spain in 2019–2021. Evidence of implementation of food environment policies was compiled in each country and validated by government officials. National experts evaluated the implementation of policies and identified priority recommendations.

Findings

Finland had the highest proportion (32%, n = 7/22) of policies shaping food environments with a “high” level of implementation. Slovenia and Poland had the highest proportion of policies rated at very low implementation (42%, n = 10/24 and 36%, n = 9/25 respectively). Policies regarding food provision, promotion, retail, funding, monitoring, and health in all policies were identified as the most important gaps across the European countries. Experts recommended immediate action on setting standards for nutrients of concern in processed foods, improvement of school food environments, fruit and vegetable subsidies, unhealthy food and beverage taxation, and restrictions on unhealthy food marketing to children.

Interpretation

Immediate implementation of policies and infrastructure support that prioritize action towards healthy food environments is urgently required to tackle the burden of obesity and diet-related non-communicable diseases in Europe.

Funding

This project has received funding from the European Union's Horizon 2020 research and innovation programme under grant agreement No 774548 and from the Joint Programming Initiative “A Healthy Diet for a Healthy Life”.

Public health interventions tackling childhood obesity at European level: A literature review

Childhood obesity pandemic, a form of malnutrition including undernutrition, and other food-regime associated risks, has universally been on the rise during the chronic period of the past 4-5 decades and is now acknowledged as one of the most "toxic fuel" accounting for poor health in the majority of countries. In order to find remedies to heal this alarming issue, a corpus of European interventions have been brought to light in the recent years. Since the vague influence and effectiveness of these measures / policies is to be further identified, their evaluation screening is underlined as a pivotal necessity. Within this framework this paper aims to critically report on the development and evaluation of the implementation of the European Union, World Health Organization Regional Office for Europe, and European Union countries' national public health policy interventions and action plans in the fight against childhood obesity. Thus, this is a narrative review synthesizing the results -following a qualitative interpretation and analysis- of recent scientific epidemiological research and review studies evidence concerning European public health interventions tackling childhood obesity, through computer-assisted literature search -via PubMed, Scopus, and Google Scholar- scientific databases. According to the literature data, it is concluded that despite the unprecedented public health challenge of addressing childhood obesity, the extent to which related European policies and programs targeting healthy nutrition, increased physical activity, and healthy lifestyle ethos are truly efficacious is still under inquiry.

Assessing the Cost of Healthy and Unhealthy Diets: A Systematic Review of Methods

PURPOSE OF REVIEW

Poor diets are a leading risk factor for chronic disease globally. Research suggests healthy foods are often harder to access, more expensive, and of a lower quality in rural/remote or low-income/high minority areas. Food pricing studies are frequently undertaken to explore food affordability. We aimed to capture and summarise food environment costing methodologies used in both urban and rural settings.

RECENT FINDINGS

Our systematic review of high-income countries between 2006 and 2021 found 100 relevant food pricing studies. Most were conducted in the USA (n = 47) and Australia (n = 24), predominantly in urban areas (n = 74) and cross-sectional in design (n = 76). All described a data collection methodology, with just over half (n = 57) using a named instrument. The main purpose for studies was to monitor food pricing, predominantly using the 'food basket', followed by the Nutrition Environment Measures Survey for Stores (NEMS-S). Comparatively, the Healthy Diets Australian Standardised Affordability and Price (ASAP) instrument supplied data on relative affordability to household incomes. Future research would benefit from a universal instrument reflecting geographic and socio-cultural context and collecting longitudinal data to inform and evaluate initiatives targeting food affordability, availability, and accessibility.

Benchmarking public policies to create healthy food environments compared to best practice: the Healthy Food Environment Policy Index in Guatemala

Background

Benchmarking the implementation of healthy food environment public policies against international best practices may accelerate the government response to prevent obesity and non-communicable diseases (NCDs) in the countries. The aim of the study was to determine the extent of food environment policy implementation in Guatemala and to identify and prioritize actions for the government to accelerate their implementation.

Methods

The INFORMAS Healthy Food Environment Policy Index (Food-EPI from the International Network for Food and Obesity/NCDs Research, Monitoring and Action Support) was used. Evidence of implementation for 50 good practice indicators within the seven food policies and six infrastructure support domains was compiled, and subsequently validated by Guatemalan government officials. A national civil society expert panel on public health and nutrition performed an online assessment of the implementation of healthy food environment policies against best international practices. The level of agreement among evaluators was measured using the Gwet second order agreement coefficient (AC2). The expert panel recommended actions for each indicator during on-site workshops and those actions were prioritized by importance and achievability.

Results

The expert panel rated implementation at zero for 26% of the indicators, very low for 28% of indicators, low for 42%, and medium for 4% of indicators (none were rated high). Indicators at medium implementation were related to the use of evidence for developing policies and ingredient list/nutrition information panels on packaged foods. Seventy-seven actions were recommended prioritizing the top 10 for immediate action. The Gwet AC2 was 0.73 (95% CI 0.67–0.80), indicating a good concordance among experts.

Conclusions

In the Food-EPI of Guatemala, almost all indicators of good practice had a low or less level of implementation. The expert panel proposed 12 priority actions to accelerate policy implementation to tackle obesity and NCDs in the country.

How theory can help to understand the potential impact of food environment policies on socioeconomic inequalities in diet: an application of Bourdieu's capital theory and the scarcity theory

Government policies that promote healthy food environments are considered promising to reduce socioeconomic inequalities in diet. Empirical evidence of effects on these inequalities, however, is relatively scarce and, with a few exceptions, tends to be inconclusive. We use two contemporary theories that help to understand socioeconomic inequalities in health and health-related behaviours (Bourdieu's capital theory and Mullainathan and Shafir's scarcity theory) to reason how policies influencing food environments may differentially impact lower and higher socioeconomic groups. In essence, these theories enable us to understand how specific elements of broader daily living conditions (e.g. social practices that lead to habitus formation, material conditions that shape experiences of scarcity) may lead to a greater benefit of certain food environment policies for the healthfulness of diets of lower or higher socioeconomic groups. We conclude that the application of theories on the mechanisms underlying socioeconomic inequalities in health can help to guide future empirical studies in testing theory-based hypotheses on differential effects of policies, and thereby enhance the development of effective policies tackling socioeconomic inequalities in dietary intakes.

Dietary behaviour and physical activity policies in Europe: learnings from the Policy Evaluation Network (PEN)

The European Policy Evaluation Network (PEN), initiated in autumn 2018, aimed at advancing the evidence base for public policies impacting dietary behaviour, physical activity and sedentary behaviours in Europe. This is needed because non-communicable diseases-the leading cause of global mortality-are substantially caused by physical inactivity and unhealthy dietary behaviours, which in turn are driven by upstream factors that have not yet been addressed effectively by prevention approaches. Thus, successful policy interventions are required that target entire populations and tackle the 'causes of the causes'. To advance our knowledge on the effective implementation of policies and their impact in terms of improving health behaviours, PEN focused on five research tasks: (i) Adaptation and implementation of a Food Environment Policy Index (Food-EPI) and development of a Physical Activity Environment Policy Index (PA-EPI); (ii) Mapping of health-related indicators needed for policy evaluation and facilitating a harmonized pan-European approach for surveillance to assess the impact of policy interventions; (iii) Refining quantitative methods to evaluate the impact of public policies; (iv) Identifying key barriers and facilitators of implementation of policies; and (v) Advance understanding the equity impact of the development, implementation and evaluation of policies aimed at promoting physical activity and a healthy diet. Finally, and in order to provide concrete evidence for policymaking, existing exemplary policies, namely sugar-sweetened beverages taxation, active transport policies and school policies on nutrition and physical activity were assessed in consideration of these five tasks. At the end of the PEN project's formal runtime, considerable advancements have been made. Here, we present an overview of the most important learnings and outputs.
