Measuring and stimulating progress on implementing widely recommended food environment policies: the New Zealand case study

Evaluating Childhood Overweight- and Obesity-Related Food Marketing Policies in China Using the Food-Environment Policy Index (Food-EPI)

OBJECTIVE

Addressing the increasing global health issue of childhood obesity, exacerbated by pervasive food marketing, this study critically evaluated China's food marketing policies in comparison with international best practices, aiming to uncover policy content and implementation gaps and inform policy enhancement strategies.

METHOD

Three key indicators were utilized from the Healthy Food-Environment Policy Index (Food-EPI)'s food promotion domain. A panel of experts (n = 13) from academic institutions, China Centers for Disease Control and Prevention, and the food industry assessed the Chinese government's policy scores and implementation levels concerning food marketing. Benchmarked against international best practices using the Food-EPI process, this evaluation encompassed context analysis, data collection, evidence-based policy action, government validation, policy rating, scoring, and results translation for government and stakeholders. The three chosen indicators specifically addressed childhood overweight- and obesity-related food marketing in broadcast media (Indicator 1), non-broadcast media (Indicator 2), and child gathering settings (Indicator 3).

RESULTS

Specifically, Indicator 1, the Single Food Marketing Indicator Score was measured at 2.31 ± 0.38, with an accompanying Food Marketing Policy Implementation Percentage of 46.2%, and Low Implementation Level. For non-broadcast mediums (Indicator 2), these metrics were gauged at 1.77 ± 0.27, 35.4%, and Low Implementation Level, respectively. In child gathering settings (Indicator 3), for efforts curbing unhealthy food promotion, a score of 2.77 ± 0.27, an implementation percentage of 55.4%, and Medium Implementation Level was obtained. Cumulatively, the overarching efficacy of food marketing policy enforcement was determined to be suboptimal, with the consolidated figures being Total Food Marketing Score as 2.28 ± 0.97, Total Food Marketing Policy Implementation Percentage as 45.6%, and Total Food Marketing Policy Implementation Level as Low.

CONCLUSION

Like many countries, China's food marketing policies and implementation have room for improvement when compared to international best practices. Recommendations include emphasizing nutritional legislation, fostering stakeholder collaboration, bolstering public health campaigns, and leveraging technology for stringent enforcement.

Neighborhood Availability and Use of Food, Physical Activity, and Social Services Facilities in Relation to Overweight and Obesity in Children and Adolescents

OBJECTIVE

To evaluate the association of a combined measure of availability and use of facilities from the food environment and overweight (including obesity) among schoolchildren, while taking into account the physical activity and social-assistance environments.

METHODS

Cross-sectional study with a probabilistic sample of schoolchildren aged 7 to 14 years living in a southern Brazilian city (n = 2026). Multilevel analyses were performed with overweight as outcome and the food environment as main exposure. Models were adjusted for the physical activity and social-assistance environments, as well as individual and other residential neighborhood characteristics.

RESULTS

Greater availability of restaurants around the home was associated with higher odds of overweight (odds ratio [OR] = 1.40; 95% CI = 1.06-1.85). Stronger associations were found for schoolchildren reporting to use restaurants (OR = 1.48; 95% CI = 1.15-1.90). This association remained significant after adjusting for the presence of other food retailers. Schoolchildren who had social-assistance facilities around their homes, but reported not to use them, showed consistently higher odds of being overweight (OR = 1.34; 95% CI = 1.01-1.78) as compared to schoolchildren who had these facilities near home and used them. The physical activity environment was not associated with the outcome.

CONCLUSIONS

Availability and use of the food and social-assistance environments were significantly associated with overweight (including obesity) among the schoolchildren. Future research should consider the use of environmental facilities in combination to their geographical availability. Our results highlight the need for policies that limit the access to obesogenic food outlets by children and adolescents.

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.

Proposed methods for evaluating efforts made by governments to prevent and mitigate corporate influence and conflicts of interest in public health policy

Background: There is evidence that corporations try to delay, weaken, and avoid the adoption of measures that would protect and improve population health. This is particularly true and problematic for health harming industries, such as those producing ultra-processed foods, alcohol, and cigarettes. Financial conflicts of interest (COI) are also problematic in policy-making because they may compromise decision-makers' loyalty and independent judgment. Public opinion is in favor of preventing and mitigating that influence from corporations and COI on public health policy. A scoping review recently identified twenty-three mechanisms that could be adopted with that purpose and which principally cover: i) transparency and disclosure; ii) identification, monitoring, and education; iii) management; iv) prohibition of interactions with the industry and/or COI. There is, however, limited knowledge on the adoption of such mechanisms by governments. We therefore propose new methods for evaluating that progress at the country level. Methods and expected results: The proposed evaluation comprises five steps: 1) Gathering information about the national context; 2) Gathering evidence on the implementation of mechanisms by national governments; 3) Verification of step 2 by government officials and policy experts and local public health experts; 4) Identification and prioritization of actions in a workshop; 5) Supporting the translation of findings into policy actions. Conclusions: The evaluation of progress made by governments in their implementation of mechanisms for preventing and mitigating the influence of corporations and COI in public health policy could help countries systematize their efforts, benchmark their progress internationally, and give perspective on particular weaknesses, approaches, and investment gaps needed for change. We will implement and validate our methods in Ireland, as a first case-study.

An assessment of implementation gaps and priority recommendations on food environment policies: the Healthy Food Environment Policy Index in Japan

OBJECTIVE

The current study aimed to evaluate policies and actions for food environments by the Japanese Government using the Healthy Food Environment Policy Index (Food-EPI).

DESIGN

Public health experts rated the extent of implementation of food environment-related Policy and the Infrastructure-support components, compared with international best practices. Subsequently, the experts proposed and prioritised future actions to address implementation gaps in an online workshop.

SETTING

Japan.

PARTICIPANTS

A total of sixty-six experts rated policy implementation by the Japanese Government and twenty-three participated in the workshop on future actions.

RESULTS

The implementations of regulations on unhealthy foods and non-alcoholic beverages were rated low in the domains of Food composition, Food labelling and Food promotion, Food prices and Food retail in the Policy component. The implementations of several domains in the Infrastructure-support component were, overall, rated at a higher level, specifically for monitoring and intelligence systems. Based on the rating, reducing health inequalities by supporting people, both economically and physically, was the highest priority for future actions in both components.

CONCLUSIONS

The current study found that Japan has a robust system for long-term monitoring of population health but lacks regulations on unhealthy foods and non-alcoholic beverages compared with international best practices. The current study confirmed the importance of continuous accumulation of evidence through national monitoring systems. Developing comprehensive regulations to restrict food marketing, sales and accessibility of unhealthy foods and non-alcoholic beverages is needed to improve the health of food environments in Japan.

Implementing healthy food environment policies in New Zealand: nine years of inaction

BACKGROUND

The INFORMAS [International Network for Food and Obesity/Non-communicable Diseases (NCDs) Research, Monitoring and Action Support] Healthy Food Environment Policy Index (Food-EPI) was developed to evaluate the degree of implementation of widely recommended food environment policies by national governments against international best practice, and has been applied in New Zealand in 2014, 2017 and 2020. This paper outlines the 2020 Food-EPI process and compares policy implementation and recommendations with the 2014 and 2017 Food-EPI.

METHODS

In March-April 2020, a national panel of over 50 public health experts participated in Food-EPI. Experts rated the extent of implementation of 47 "good practice" policy and infrastructure support indicators compared to international best practice, using an extensive evidence document verified by government officials. Experts then proposed and prioritized concrete actions needed to address the critical implementation gaps identified. Progress on policy implementation and recommendations made over the three Food-EPIs was compared.

RESULTS

In 2020, 60% of the indicators were rated as having "low" or "very little, if any" implementation compared to international benchmarks: less progress than 2017 (47%) and similar to 2014 (61%). Of the nine priority actions proposed in 2014, there was only noticeable action on one (Health Star Ratings). The majority of actions were therefore proposed again in 2017 and 2020. In 2020 the proposed actions were broader, reflecting the need for multisectoral action to improve the food environment, and the need for a mandatory approach in all policy areas.

CONCLUSIONS

There has been little to no progress in the past three terms of government (9 years) on the implementation of policies and infrastructure support for healthy food environments, with implementation overall regressing between 2017 and 2020. The proposed actions in 2020 have reflected a growing movement to locate nutrition within the wider context of planetary health and with recognition of the social determinants of health and nutrition, resulting in recommendations that will require the involvement of many government entities to overcome the existing policy inertia. The increase in food insecurity due to COVID-19 lockdowns may provide the impetus to stimulate action on food polices.

A systematic review of school health policy measurement tools: implementation determinants and outcomes

BACKGROUND

Governments in some countries or states/provinces mandate school-based policies intended to improve the health and well-being of primary and secondary students and in some cases the health of school staff. Examples include mandating a minimum time spent per week in programmed physical activity, mandating provision of healthy foods and limiting fat content of school meals, and banning tobacco products or use on school campuses. Although school health researchers have studied whether schools, districts, or states/provinces are meeting requirements, it is unclear to what extent implementation processes and determinants are assessed. The purposes of the present systematic review of quantitative measures of school policy implementation were to (1) identify quantitative school health policy measurement tools developed to measure implementation at the school, district, or state/provincial levels; (2) describe the policy implementation outcomes and determinants assessed and identify the trends in measurement; and (3) assess pragmatic and psychometric properties of identified implementation measures to understand their quality and suitability for broader application.

METHODS

Peer-reviewed journal articles published 1995-2020 were included if they (1) had multiple-item quantitative measures of school policy implementation and (2) addressed overall wellness, tobacco, physical activity, nutrition, obesity prevention, or mental health/bullying/social-emotional learning. The final sample comprised 86 measurement tools from 67 peer-review articles. We extracted study characteristics, such as psychometric and pragmatic measure properties, from included articles based on three frameworks: (1) Implementation Outcomes Framework, (2) Consolidated Framework for Implementation Research, and (3) Policy Implementation Determinants Framework.

RESULTS

Most implementation tools were developed to measure overall wellness policies which combined multiple policy topics (n = 35, 40%) and were in survey form (n = 75, 87%). Fidelity was the most frequently prevalent implementation outcome (n = 70, 81%), followed by adoption (n = 32, 81%). The implementation determinants most assessed were readiness for implementation, including resources (n = 43, 50%), leadership (n = 42, 49%), and policy communication (n = 41, 48%). Overall, measures were low-cost and had easy readability. However, lengthy tools and lack of reported validity/reliability data indicate low transferability.

CONCLUSIONS

Implementation science can contribute to more complete and rigorous assessment of school health policy implementation processes, which can improve implementation strategies and ultimately the intended health benefits. Several high-quality measures of implementation determinants and implementation outcomes can be applied to school health policy implementation assessment. Dissemination and implementation science researchers can also benefit from measurement experiences of school health researchers.

A narrative review of regulatory governance factors that shape food and nutrition policies

Food composition, marketing restrictions, nutrition labeling, and taxation policies are recommended for preventing diet-related noncommunicable diseases. In view of the increasing but variable adoption of food policies globally, this narrative review examines the actors, regulatory frameworks, and institutional contexts that shape the development, design, and implementation of these policies. We found a diverse range of actors using various strategies, including advocacy, framing, and evidence generation to influence policy agendas. We identified diverse regulatory designs used in the formulation and implementation of the policies: command and control state regulation for taxes and menu labels, quasi-regulation for sodium reformulation, and co-regulation and industry self-regulation for food marketing policies. Quasi-regulation and industry self-regulation are critiqued for their voluntary nature, lack of independence from the industry, and absence of (or poor) monitoring and enforcement systems. The policy instrument design and implementation best practices highlighted in this review include clear policy goals and rigorous standards that are adequately monitored and enforced. Future research should examine how these combinations of regulatory governance factors influence policy outcomes.

Identifying implementation gaps and priorities for the Singapore government to improve food environment policies: perspectives from a local expert panel

OBJECTIVE

Singapore, an urbanised, developed nation, with a high reliance on food importation and a high prevalence of eating out is facing rising rates of obesity and diabetes. The objective of the current study was to characterise and evaluate the Singapore government's policies to improve the food environment and to identify and prioritise concrete actions.

DESIGN

The Healthy Food Environment Policy Index tool and process were used. An expert panel rated the Singapore government's implementation of forty-seven indicators compared with international best practice in 2018. Indicators were prioritised, and specific recommendations were proposed by panel.

SETTING

Singapore.

PARTICIPANTS

Twenty experts primarily from academia.

RESULTS

As compared with international benchmarks, the level of implementation of most indicators (thirty-three indicators, 70 %) by the Singapore government was evaluated as being at least moderate. Highly rated indicators included those related to provision of healthier meals at school, supporting the use of healthier ingredients by food vendors and governmental leadership. More policy indicators (6, 26 %) as compared with infrastructure support indicators (2, 8 %) received a 'very little or no implementation' rating. After rating, the experts prioritised eleven indicators and proposed thirty-one actions informed by several considerations including those of effectiveness, political acceptability, feasibility and unique characteristics of food retail in Singapore.

CONCLUSIONS

Supported by documented evidence, an independent expert panel identified areas of strengths and provided specific recommendations to meaningfully improve the Singapore food environment to facilitate healthier eating. Fundamental recommendations including improving nutrition profiling and strengthening monitoring systems have the potential to positively influence environments across policy domains.

Barriers and facilitators to successful management of type 2 diabetes mellitus in Latin America and the Caribbean: A systematic review

BACKGROUND

Given that most evidence-based recommendations for managing type 2 diabetes mellitus (T2DM) are generated in high-income settings, significant challenges for their implementation exist in Latin America and the Caribbean region (LAC), where the rates of T2DM and related mortality are increasing. The aim of this study is to identify the facilitators and barriers to successful management of T2DM in LAC, from the perspectives of patients, their families or caregivers, healthcare professionals, and/or other stakeholders.

METHODS

We conducted a systematic review in MEDLINE, Web of Science, SciELO, and LILACS. We included studies of disease management, prevention of complications and risk factor management. We qualitatively synthesized the verbatim text referring to barriers and/or facilitators of diabetes management according to the Theoretical Domain Framework and described their relative frequencies.

FINDINGS

We included 60 studies from 1,595 records identified. 54 studies (90%) identified factors related to the environmental context and resources, highlighting the importance of questions related to health care access or lack of resources in the health system, and the environmental context and living conditions of the patients. Issues related to "social influences" (40 studies) and "social/professional role and identity" (37 studies) were also frequently addressed, indicating the negative impact of lack of support from family and friends and clinicians' paternalistic attitude. 25 studies identified patients beliefs as important barriers, identifying issues such as a lack of patients' trust in the effectiveness of the medication and/or the doctor's advice, or preferences for alternative therapies.

CONCLUSIONS

Successful diabetes management in LAC is highly dependent on factors that are beyond the control of the individual patients. Successful disease control will require emphasis on public policies to reinforce health care access and resources, the promotion of a patient-centred care approach, and health promoting infrastructures at environmental level.

Nutrition Policy and Individual Struggle to Eat Healthily: The Question of Public Support

The evidence for the effectiveness of nutrition policy interventions is growing. For the implementation of such interventions, social acceptability is crucial. Therefore, this study provides insight into public support for nutrition policy measures such as labelling and taxation. Further it analyses the level of acceptance in a quantitative segmentation approach. A new element to our approach is the comparison of different policy instruments, focusing on the interaction between policy acceptance and the perceived individual struggle to eat healthily. The survey was conducted in November 2017 and a total of 1035 German consumers are included in the data. The results indicate that the majority of German citizens accept nutrition policy interventions. Based on a cluster analysis, five different target groups according to the general acceptance of policy interventions and their own struggle to eat healthily are derived. The five-cluster solution reveals that both consumers who tend to eat a healthy diet as well as those who have problems with their diet support nutritional interventions. This shows that the perceived own struggle to eat healthily does not predict whether consumers accept nutrition policy interventions.

The first INFORMAS national food environments and policies survey in New Zealand: A blueprint country profile for measuring progress on creating healthy food environments

The International Network for Food and Obesity/NCDs Research, Monitoring and Action Support aims to benchmark national food environments. This study proposes a blueprint country profile to measure progress on creating healthy food environments, based on the results of the first, comprehensive survey in New Zealand (NZ). We assessed the implementation of national food environment policies and food industry commitments to improve population nutrition and the strength and comprehensiveness of public sector settings' nutrition policies. The healthiness of the packaged food supply, including health-related labelling, was evaluated. Food environments were measured in 833 schools, 204 supermarkets, 1500 takeaway outlets, 28 hospitals, 70 sport centres, and around all NZ schools. Food swamps, defined as areas with high relative density of unhealthy food outlets, were identified, and food marketing to children on television, websites, social media and packages, in magazines, and in and around schools was measured. The cost differential between healthy and current household diets was calculated for different population groups. NZ's food environment profile is largely unhealthy, and there are inequalities in access to healthy food environments. It is anticipated that the proposed country profile can help other countries tackle unhealthy food environments through increasing accountability of governments and the industry.

The INFORMAS healthy food environment policy index (Food-EPI) in Mexico: An assessment of implementation gaps and priority recommendations

Mexico is one of the countries with the highest prevalence of obesity and recently declared a national epidemic of diabetes. Healthy food environments have the potential to improve the diet of the population and decrease the burden of disease. The aim of the study was to assess the efforts of the Mexican Government towards creating healthier food environments using the Healthy Food Environment Policy Index (Food-EPI). The tool was developed by the International Network for Food and Obesity/Non-communicable Diseases Research, Monitoring and Action Support (INFORMAS). Then, it was adapted to the Latin-American context and assessed the components of policy and infrastructure support. Actors from academia, civil society, government, and food industry assessed the level of implementation of food policies compared with international best practices. Actors were classified as (1) independents from academia and civil society (n = 36), (2) government (n = 28), and (3) industry (n = 6). The indicators with the highest percentage of implementation were those related to monitoring and intelligence. Those related to food retail were rated lowest. When stratified by type of actor, the government officials rated several indicators at a higher percentage of implementation compared with independent actors. None of the indicators were rated at high implementation. Government officials and independent actors agreed upon nine priority actions to improve the food environment in Mexico. These actions have the potential to improve government commitment and advocacy efforts to create healthier food environments.

An 11-country study to benchmark the implementation of recommended nutrition policies by national governments using the Healthy Food Environment Policy Index, 2015-2018

The Healthy Food Environment Policy Index (Food-EPI) aims to assess the extent of implementation of recommended food environment policies by governments compared with international best practices and prioritize actions to fill implementation gaps. The Food-EPI was applied in 11 countries across six regions (2015-2018). National public health nutrition panels (n = 11-101 experts) rated the extent of implementation of 47 policy and infrastructure support good practice indicators by their government(s) against best practices, using an evidence document verified by government officials. Experts identified and prioritized actions to address implementation gaps. The proportion of indicators at "very low if any," "low," "medium," and "high" implementation, overall Food-EPI scores, and priority action areas were compared across countries. Inter-rater reliability was good (GwetAC2 = 0.6-0.8). Chile had the highest proportion of policies (13%) rated at "high" implementation, while Guatemala had the highest proportion of policies (83%) rated at "very low if any" implementation. The overall Food-EPI score was "medium" for Australia, England, Chile, and Singapore, while "very low if any" for Guatemala. Policy areas most frequently prioritized included taxes on unhealthy foods, restricting unhealthy food promotion and front-of-pack labelling. The Food-EPI was found to be a robust tool and process to benchmark governments' progress to create healthy food environments.

Beverage consumption and energy intake among Canadians: analyses of 2004 and 2015 national dietary intake data

Background

Among adults and children consuming Western diets, beverages are significant sources of free sugars, saturated fats, excess calories, and alcohol, with relevance to chronic disease risk. The impact of recent healthy eating policies and beverage market evolutions on population-level consumption patterns in Canada is unknown. The current study examined trends in intake of a range of beverage types among a nationally-representative sample of Canadians, with stratification by socio-demographic characteristics.

Methods

The 2004 (n = 34,775) and 2015 (n = 20,176) nutrition-focused cycles of the Canadian Community Health Surveys are cross-sectional surveys representative of the population of the 10 Canadian provinces. Based on a single multiple-pass 24-h dietary recall for each participant, fluids consumed as beverages were grouped into seven categories. Using linear regression, reported intake (volume, ml and energy, kcal) of each category was characterized over time and in relation to sex, age, ethnicity, income, body mass index (BMI), and province of residence.

Results

In 2015, Canadians reported consuming an average of 1806 ml (275 kcal) fluids as beverages per day, including: plain water 867 ml (0 kcal); other unsweetened beverages, e.g. coffee, 364 ml (6 kcal); sugar-sweetened beverages (SSBs) 204 ml (99 kcal); plain milk 132 ml (64 kcal); alcoholic drinks 120 ml (71 kcal); 100% juice 74 ml (34 kcal); and diet or low calorie beverages 44 ml (2 kcal). Differential consumption was observed across socio-demographic groups, with high consumption of sugary drinks (i.e., SSBs and 100% juice) and alcohol across groups. From 2004 to 2015, the reported volumes of beverages consumed decreased by 10% (energy: − 24%). With adjustment for socio-demographic characteristics, there were significant changes (p < 0.001) over time in intake of: 100% juice − 40% (− 38%); plain milk − 37% (− 35%); SSBs − 26% (− 20%); diet or low calorie beverages (− 46%); and other unsweetened beverages − 11% (− 42%). The volume of plain water consumed increased by 10% (p < 0.0001). Intake of alcoholic (volume and energy) and diet or light beverages did not change significantly.

Conclusions

Lower intake of beverages was reported by Canadians in 2015 versus 2004, with a shift towards plain water. Consumption of sugary drinks decreased, but these beverages continue to contribute substantially to Canadians' overall energy intake. The findings underscore the need for policies to further reduce the consumption of sugary and alcoholic beverages, as well as calories from beverages.

Benchmarking the commitments related to population nutrition and obesity prevention of major food companies in New Zealand

OBJECTIVES

To benchmark comprehensiveness, specificity and transparency of the nutrition-related commitments of major food companies in New Zealand.

METHODS

We applied the Business Impact Assessment on Obesity and Population Level Nutrition (BIA-Obesity). The largest 25 New Zealand companies in each of the packaged food (n = 15), non-alcoholic beverage (n = 2), supermarket (n = 2) and quick-service restaurant (n = 6) sectors were selected. Publicly available information on commitments was collected through an online search. Representatives from each company were asked to review and/or supplement the information collected. Commitments were then assessed, and recommendations made at the company and sector levels.

RESULTS

Overall scores ranged from 0 to 75% across all companies with a median score of 38%. The best-performing domain was 'corporate nutrition strategy' (median score = 55%), and the worst-performing domain was 'product accessibility' (median score = 0%). Twelve out of 25 companies fully engaged with the process.

CONCLUSIONS

The comprehensiveness, specificity and transparency of company commitments varied but were low overall. In the absence of strong industry commitments, government regulations, such as restrictions on unhealthy food marketing, are urgently needed. Future assessments should incorporate performance measures.

A Virtual Reality Food Court to Study Meal Choices in Youth: Design and Assessment of Usability

Background

Regular consumption of take-out and fast foods with sugary drinks is associated with poor quality diets and higher prevalence of obesity. Among the settings where such food is consumed is the food court typically found in shopping malls prominent in many countries.

Objective

The objective of this research was to develop a virtual reality food court that could be used to test food environmental interventions, such as taxation, and ultimately to facilitate the selection of healthier food choices.

Methods

Fourteen food courts in Sydney, Australia were selected to include those in the city center and suburbs of high and low socioeconomic status. Researchers visited the courts to collect information on number and type of food outlets, all menu items for sale, cost of foods and beverages and sales promotions. This information was used to assemble 14 food outlets typically found in food courts, and representative menus were compiled. The UNITY gaming platform was used to design a virtual reality food court that could be used with HTC VIVE goggles. Participants navigated the virtual reality food court using the head-mounted display, keyboard, and mouse and selected a lunch meal, including food and beverage. A validated questionnaire on presence within the virtual reality food court and system usability was completed at the end of the session. The constructs for presence included a sense of control, sensory fidelity, realism, distraction, and involvement. Questions were rated on a scale from 1 (worst) through 7 (best) for each of 28 questions giving a maximum total score of 196. The systems usability scale (SUS) that gives a final score out of 100 was also assessed.

Results

One hundred and sixty-two participants with a mean age of 22.5 (SD 3.1) years completed the survey. The mean score for total presence was 144 (SE 1.4) consisting of control: 62.1 (SE 0.8), realism: 17.5 (SE 0.2), involvement: 9.6 (SE 0.2), sensory fidelity: 34.9 (SE 0.4), and distraction: 24.0 (SE 0.3). The mean SUS was 69 (SE 1.1).

Conclusions

Virtual reality shows promise as a tool to study food choice for test interventions to inform practice and policy.
