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.

What counts? Adding nuance to retail food environment measurement tools in a Canadian context.

OBJECTIVE: Limitations of traditional geospatial measures, like the modified Retail Food Environment Index (mRFEI), are well documented. In response, we aimed to: (1) extend existing food environment measures by inductively developing subcategories to increase the granularity of healthy v. less healthy food retailers; (2) establish replicable coding processes and procedures; and (3) demonstrate how a food retailer codebook and database can be used in healthy public policy advocacy. DESIGN: We expanded the mRFEI measure such that 'healthy' food retailers included grocery stores, supermarkets, hypermarkets, wholesalers, bulk food stores, produce outlets, butchers, delis, fish and seafood shops, juice/smoothie bars, and fresh and healthy quick-service retailers; and 'less healthy' food retailers included fast-food restaurants, convenience stores, coffee shops, dollar stores, pharmacies, bubble tea restaurants, candy stores, frozen dessert restaurants, bakeries, and food trucks. Based on 2021 government food premise licences, we used geographic information systems software to evaluate spatial accessibility of healthy and less healthy food retailers across census tracts and in proximity to schools, calculating differences between the traditional v. expanded mRFEI. SETTING: Calgary and Edmonton, Canada. PARTICIPANTS: N/A. RESULTS: Of the 10 828 food retailers geocoded, 26 % were included using traditional mRFEI measures, while 53 % were included using our expanded categorisation. Changes in mean mRFEI across census tracts were minimal, but the healthfulness of food environments surrounding schools significantly decreased. CONCLUSIONS: Overall, we show how our mRFEI adaptation, and transparent reporting on its use, can promote more nuanced and comprehensive food environment assessments to better support local research, policy and practice innovations.

Experiences and perceived outcomes of a grocery gift card programme for households at risk of food insecurity.

OBJECTIVE: This study explored programme recipients' and deliverers' experiences and perceived outcomes of accessing or facilitating a grocery gift card (GGC) programme from I Can for Kids (iCAN), a community-based programme that provides GGC to low-income families with children. DESIGN: This qualitative descriptive study used Freedman et al's framework of nutritious food access to guide data generation and analysis. Semi-structured interviews were conducted between August and November 2020. Data were analysed using directed content analysis with a deductive-inductive approach. PARTICIPANTS: Fifty-four participants were purposively recruited, including thirty-seven programme recipients who accessed iCAN's GGC programme and seventeen programme deliverers who facilitated it. SETTING: Calgary, Alberta, Canada. RESULTS: Three themes were generated from the data. First, iCAN's GGC programme promoted a sense of autonomy and dignity among programme recipients as they appreciated receiving financial support, the flexibility and convenience of using GGC, and the freedom to select foods they desired. Recipients perceived these benefits improved their social and emotional well-being. Second, recipients reported that the use of GGC improved their households' dietary patterns and food skills. Third, both participant groups identified programmatic strengths and limitations. CONCLUSION: Programme recipients reported that iCAN's GGC programme provided them with dignified access to nutritious food and improved their households' finances, dietary patterns, and social and emotional well-being. Increasing the number of GGC provided to households on each occasion, establishing clear and consistent criteria for distributing GGC to recipients, and increasing potential donors' awareness of iCAN's GGC programme may augment the amount of support iCAN could provide to households.

It takes a community: exploring APPLE Schools' impact within and beyond school walls in Canada.

Childhood is a critical stage to develop healthy behaviours, and the school years are an important developmental period in which children are learning and growing. School-based health promotion interventions are increasingly using the comprehensive school health (CSH) approach that has been found effective at improving health behaviours, while adapting to the school and community context to create and sustain a healthy school culture. The interconnected environments of school, home and community are key to the CSH approach, however, there is minimal research that has been conducted to determine the impact at the community-level. This research used a qualitative multiple case study design to explore the influence of a school-based health promotion intervention, APPLE Schools, on the school and community environments from the perspectives of school staff in Alberta, Canada. Twenty-two participants participated in walking interviews in five schools. The walking interview approach combined interviewing and field observation and empowered participants to share their local expertise and knowledge within the context of school and community environments. Interviews were transcribed and analysed using an inductive thematic approach. Four themes were identified: APPLE schools look different, APPLE Schools build champions, APPLE Schools builds community partnerships and APPLE Schools honours community culture. Health promotion practice in schools was uniquely adapted based on strengths and needs of each school and was broadly influenced by the community outside of school walls. In sum, it was found that school-based health promotion reaches beyond school walls and can influence the broader community environment.

Childhood is a critical stage to develop healthy behaviours, and the school years are an important developmental period in which children are learning and growing. School-based health promotion interventions are increasingly using the comprehensive school health (CSH) approach. CSH has been found effective in improving health and educational outcomes, including quality of life, healthy eating, physical activity, mental wellness and academic achievement. The interconnected environments of school, home and community are key to the CSH approach, however, there is minimal research that has been conducted to determine the impact at the community-level. This research used a qualitative multiple case study design to explore the influence of a school-based health promotion intervention, APPLE Schools, on the school and community environments from the perspectives of school staff in Canada. Twenty-two participants from five schools, took part in walking interviews. Interviews were transcribed and analysed for patterns and common themes. Four themes were identified: APPLE schools look different, APPLE Schools build champions, APPLE Schools builds community partnerships and APPLE Schools honours community culture. It was found that school-based health promotion reaches beyond school walls and can influence the broader community environment. This understanding will support stronger school­community relationships in future interventions.

Australians support for policy initiatives addressing unhealthy diet: a population-based study.

To inform public health policy implementation in Australia, our study investigated the level of public support for six policy initiatives addressing unhealthy diet. The policy initiatives included taxing soft drinks and energy drinks, taxing less healthy food and beverage purchases, zoning to restrict the supply of junk foods near schools, prohibiting advertising and promotion of less healthy food and beverages to children under the age of 16 and restricting sugar-sweetened beverages from vending machines in schools, and public places. Data from a cross-sectional population-based study for 4040 Australians aged 15+ years, were analysed. A high overall support across all policy initiatives was observed. Nearly three-quarter of public support was observed for policy initiatives targeting children (zoning to restrict the supply of junk food near schools, prohibiting advertising and promotion of less healthy food and beverages to children under the age of 16 and restricting sugars-sweetened beverages from vending machines in schools), and half of Australians supported policy initiatives of taxing soft drinks and energy drinks and taxing less healthy food and beverage purchases. Australian women and those with tertiary level of education were more likely to support public health initiatives targeting children and all policy initiatives respectively. Interestingly, young adults expressed low level of support for all policy initiatives. The study demonstrated considerable public support for policy initiatives focussed on protecting children from unhealthy diet in Australia. Framing, designing and implementing policies targeting children is potentially a good starting point for policymakers to create a health promoting food environment.

'My coupons are like gold': experiences and perceived outcomes of low-income adults participating in the British Columbia Farmers' Market Nutrition Coupon Program.

OBJECTIVE: The British Columbia Farmers' Market Nutrition Coupon Program (FMNCP) provides low-income households with coupons valued at $21/week for 16 weeks to purchase healthy foods in farmers' markets. Our objective was to explore FMNCP participants' experiences of accessing nutritious foods, and perceived programme outcomes. DESIGN: The current study used qualitative description methodology. Semi-structured interviews were conducted with FMNCP participants during the 2019 farmers' market season. Directed content analysis was used to analyse the data, whereby the five domains of Freedman et al.'s framework of nutritious food access provided the basis for an initial coding scheme. Data that did not fit within the framework's domains were coded inductively. SETTING: One urban and two rural communities in British Columbia, Canada. PARTICIPANTS: Twenty-eight adults who were participating in the FMNCP. RESULTS: Three themes emerged: autonomy and dignity, social connections and community building, and environmental and programmatic constraints. Firstly, the programme promoted a sense of autonomy and dignity through financial support, increased access to high-quality produce, food-related education and skill development and mitigating stigma and shame. Secondly, shopping in farmers' markets increased social connections and fostered a sense of community. Finally, participants experienced limited food variety in rural farmers' markets, lack of transportation and challenges with redeeming coupons. CONCLUSIONS: Participation in the FMNCP facilitated access to nutritious foods and enhanced participants' diet quality, well-being and health. Strategies such as increasing the amount and duration of subsidies and expanding programmes may help improve participants' experiences and outcomes of farmers' market food subsidy programmes.

"We're categorized in these sizes-that's all we are": uncovering the social organization of young women's weight work through media and fashion.

BACKGROUND: For decades, dominant weight discourses have led to physical, mental, and social health consequences for young women in larger bodies. While ample literature has documented why these discourses are problematic, knowledge is lacking regarding how they are socially organized within institutions, like fashion and media, that young women encounter across their lifespan. Such knowledge is critical for those in public health trying to shift societal thinking about body weight. Therefore, we aimed to investigate how young women's weight work is socially organized by discourses enacted in fashion and media, interpreting work generously as any activity requiring thought or intention. METHODS: Using institutional ethnography, we learned from 14 informants, young women aged 15-21, in Edmonton, Canada about the everyday work of growing up in larger bodies. We conducted 14 individual interviews and five repeated group interviews with a subset (n = 5) of our informants. A collaborative investigation of weight-related YouTube videos (n = 45) elicited further conversations with two informant-researchers about the work of navigating media. Data were integrated and analyzed holistically. RESULTS: Noticing the perpetual lack of larger women's bodies in fashion and media, informants learned from an early age that thinness was required for being seen and heard. Informants responded by performing three types of work: hiding their weight, trying to lose weight, and resisting dominant weight discourses. Resistance work was aided by social media, which offered informants a sense of community and opportunities to learn about alternative ways of knowing weight. However, social media alleging body acceptance or positivity content often still focused on weight loss. While informants recognized the potential harm of engagement with commercial weight loss industries like diet and exercise, they felt compelled to do whatever it might take to achieve a "normal woman body". CONCLUSIONS: Despite some positive discursive change regarding body weight acceptance in fashion and media, this progress has had little impact on the weight work socially expected of young women. Findings highlight the need to broaden public health thinking around how weight discourses are (re)produced, calling for intersectoral collaboration to mobilize weight stigma evidence beyond predominantly academic circles into our everyday practices.

Citizen science in monitoring food environments: a qualitative collective case study of stakeholders' experiences during the Local Environment Action on Food project in Alberta, Canada.

BACKGROUND: Citizen science bears potential to build a comprehensive view of global food environments and create a broader discussion about how to improve them. Despite its potential, citizen science has not been fully utilised in food environment research. Thus, we sought to explore stakeholders' experiences of the Local Environment Action on Food (LEAF) project, a community-based intervention that employs a citizen science approach to monitoring food environments. METHODS: We used a qualitative collective case study design to explore citizen science through the LEAF process in seven communities in Alberta, Canada. Data generating strategies included semi-structured interviews with citizen scientists (n = 26), document review of communities' Mini Nutrition Report Cards (n = 7), and researcher observation. Data were analyzed in a multi-phase process, using Charmaz's constant comparison analysis strategy. RESULTS: Analysis revealed two main themes: relationship building and process factors. Communities used three interconnected strategies, engaging the right people, treading lightly, and reaching a consensus, to navigate the vital but challenging relationship building process. Process factors, which were influences on the LEAF process and relationship building, included the local context, flexibility in the LEAF process, and turnover among LEAF community groups. CONCLUSION: Citizen science through the LEAF project supported the creation and application of food environment evidence: it enabled residents to collect and interpret local food environment data, develop realistic recommendations for change, and provided them with an evidence-based advocacy tool to support the implementation of these recommendations. We recommend a web application that enables independent community food environment assessments. Such a tool could stimulate and sustain citizen involvement in food environment efforts, helping to build the necessary evidence base and promote the creation of healthy food environments.

Local Environment Action on Food project: impact of a community-based food environment intervention in Canada.

Children are exposed to food environments that make nutrient-poor, energy-dense food cheap, readily available and heavily marketed; all conditions with potential negative impacts on diet and health. While the need for programmes and policies that improve the status of food environments is clear, greater public support is needed for governments to act. The purpose of this qualitative collective case study was to examine if community engagement in the Local Environment Action on Food (LEAF) project, a community-based food environment intervention in Alberta, Canada, could build public support and create action to promote healthy food environments. Semi-structured interviews with a purposeful sample of 26 stakeholders from 7 communities explored LEAF's impact and stakeholder experiences creating change. Data collection and analysis were iterative, following Charmaz's constant comparative analysis strategy. Participants reported environmental and community impacts from LEAF. Notably, LEAF created a context-specific tool, a Mini Nutrition Report Card, that communities used to promote and support food environment action. Further, analysis outlined perceived barriers and facilitators to creating community-level food environment action, including level of engagement in LEAF, perceived controllability, community priorities, policy enforcement and resources. Findings from this study suggest that community-based interventions, such as LEAF, can help build community capacity and reduce existing barriers to community-level food environment action. Thus, they can provide an effective method to build public awareness, demand and action for healthier food environments.

Appetite for change? Facilitators and barriers to nutrition guideline implementation in Canadian recreational facilities.

As providers of community-based physical activity programs, recreation and sports facilities serve as an important resource for health promotion. Unfortunately, the food environments within these settings often do not reflect healthy eating guidelines. This study sought to describe facilitators and barriers to implementing provincial nutrition guidelines in recreation and sports facilities in three Canadian provinces with nutrition guidelines. Semi-structured interviews were analysed thematically to identify facilitators and barriers to implementing provincial nutrition guidelines. Facilitators and barriers were then categorised using a modified "inside out" socio-ecological model that places health-related and other social environments at the centre. A total of 32 semi-structured interviews were conducted at two time-points across the three guideline provinces. Interview participants included recreation staff managers, facility committee or board members and recreation volunteers. Eight facilitators and barriers were identified across five levels of the inside out socio-ecological model. Facilitators included provincial or municipal expectations of guideline implementation, clear communication to staff around guideline directives and the presence of a champion within the community or facility who supported guideline implementation. Barriers included unhealthy food culture within community, competition from other food providers and issues within food service contracts that undermined healthy food provision. Findings reinforce the importance of top down (clear expectations regarding guideline implementation at the time of approval) and bottom up (need for buy-in from multiple stakeholders) approaches to ensure successful implementation of nutrition guidelines. The application of a modified socio-ecological model allowed for a more nuanced understanding of leverage points to support successful guideline implementation. Lay summary Healthy eating is an important behaviour for preventing chronic diseases. Supporting people to access healthy foods in places where they live, learn, work or play is a public health priority. Recreation and sports facilities are a setting where people can be physically active. Unfortunately, the food environment in these settings may not reflect nutrition guidelines. In this study, we interviewed key stakeholders from recreation and sports facilities in three Canadian provinces who had put guidelines for healthy eating in place. We used a specific framework to do this called the inside out socio-ecological model. Eight facilitators and barriers were identified using this model. Facilitators included provincial or municipal expectations of guideline implementation, clear communication to staff around guideline directives and the presence of a champion within the community or facility who supported guideline implementation. Barriers included unhealthy food culture within community, competition from other food providers and issues within food service contracts that undermined healthy food provision. Our findings can help people working in recreation and sports facilities to identify issues that may help or hinder healthy food provision in these settings.

A Nutrition Report Card on food environments for children and youth: 5 years of experience from Canada.

OBJECTIVE: In 2014, a Nutrition Report Card (NRC) was developed as a sustainable, low-cost framework to assess the healthfulness of children's food environments and highlight action to support healthy eating. We summarise our experiences in producing, disseminating, evaluating and refining an annual NRC in a Canadian province from 2015 to 2019. DESIGN: To produce the NRC, children's food environment indicator data are collected, analyzed and compiled for consensus grading by an Expert Working Group of researchers and practitioners. Knowledge translation activities are tailored annually to the needs of target audiences: researchers, practitioners, policymakers and the public. Evaluation of reach is conducted through diverse strategies, including tracking media coverage and website traffic. Assessment of impact on diets and health outcomes is planned. SETTING: Alberta, Canada. PARTICIPANTS: Not applicable. DISCUSSION: The grading process has facilitated refining the NRC to enhance its relevance and utility as a tool for its target audiences. Its public release consistently captures media interest and policymakers' attention. The importance of partnerships in revealing data sources and in strategising to enhance policy approaches to improve food environments is apparent. The NRC has benchmarked progress and stimulated dialogue regarding healthy food environments for children. CONCLUSIONS: The NRC may help to foster a supportive climate for improving the quality of children's food environments. As an engaging and accessible document, the NRC represents a key mechanism for collating data related to children's food environments and ensuring it reaches the audiences best positioned to use it. Efforts are underway to expand the NRC across Canada.

Eat, play, live: a randomized controlled trial within a natural experiment examining the role of nutrition policy and capacity building in improving food environments in recreation and sport facilities.

BACKGROUND: Recreation and sport facilities often have unhealthy food environments that may promote unhealthy dietary patterns among children. In response, some Canadian provinces have released voluntary nutrition guidelines for recreation and sport facilities, however implementation has been limited. Organizational capacity building may overcome barriers to implementing guidelines. Eat, Play, Live was a randomized controlled trial embedded within a natural experiment that tested the impact of an 18 month capacity building intervention (CBI) in enhancing implementation of provincial nutrition guidelines, and whether nutrition guidelines were associated with positive changes. Primary outcomes were facility capacity, policy development and food environment quality. METHODS: Recreation and sport facilities in three guideline provinces were randomized into a guideline + CBI (GL + CBI; n = 17) or a guideline only comparison condition (GL-ONLY; n = 15). Facilities in a province without guidelines constituted a second comparison condition (NO-GL; n = 17). Facility capacity, policy development, and food environment quality (vending and concession) were measured and compared at baseline and follow-up across conditions using repeated measures ANOVA and Chi-square statistics. Healthfulness of vending and concession items was rated as Do Not Sell (least nutritious), Sell Sometimes or Sell Most (most nutritious). RESULTS: There were significant time by condition effects, with significant increases in facility capacity (mean ± SD: 30.8 ± 15.6% to 62.3 ± 22.0%; p <  0.01), nutrition policy development (17.6% developed new policies; p = 0.049), overall quality of the concession food environment (14.7 ± 8.4 to 17.5 ± 7.2; p <  0.001), and in the proportion of Sell Most (3.7 ± 4.4% to 11.0 ± 9.0%; p = 0.002) and Sell Sometimes vending snacks (22.4 ± 14.4% to 43.8 ± 15.8%; p <  0.001) in GL + CBI facilities, with a significant decline in Do Not Sell vending snacks (74.0 ± 16.6% to 45.2 ± 20.1%; p <  0.001). CONCLUSIONS: Significant improvements in facility capacity, policy development and food environment quality occurred in recreation and sport facilities that were exposed to nutrition guidelines and participated in a CBI. Outcomes did not improve in facilities that were only passively or not at all exposed to guidelines. Ongoing capacity building may enhance implementation of voluntary nutrition guidelines, however food environments remained overwhelmingly unhealthy, suggesting additional scope to enhance implementation.

Assessing general public and policy influencer support for healthy public policies to promote healthy eating at the population level in two Canadian provinces.

OBJECTIVE: To assess and compare the favourability of healthy public policy options to promote healthy eating from the perspective of members of the general public and policy influencers in two Canadian provinces. DESIGN: The Chronic Disease Prevention Survey, administered in 2016, required participants to rank their level of support for different evidence-based policy options to promote healthy eating at the population level. Pearson's χ 2 significance testing was used to compare support between groups for each policy option and results were interpreted using the Nuffield Council on Bioethics' intervention ladder framework. SETTING: Alberta and Québec, Canada.ParticipantsMembers of the general public (n 2400) and policy influencers (n 302) in Alberta and Québec. RESULTS: General public and policy influencer survey respondents were more supportive of healthy eating policies if they were less intrusive on individual autonomy. However, in comparing levels of support between groups, we found policy influencers indicated significantly stronger support overall for healthy eating policy options. We also found that policy influencers in Québec tended to show more support for more restrictive policy options than their counterparts from Alberta. CONCLUSIONS: These results suggest that additional knowledge brokering may be required to increase support for more intrusive yet impactful evidence-based policy interventions; and that the overall lower levels of support among members of the public may impede policy influencers from taking action on policies to promote healthy eating.

Advancing Strategies for Agenda Setting by Health Policy Coalitions: A Network Analysis of the Canadian Chronic Disease Prevention Survey.

Health in all policies can address chronic disease morbidity and mortality by increasing population-level physical activity and healthy eating, and reducing tobacco and alcohol use. Both governmental and nongovernmental policy influencers are instrumental for health policy that modifies political, economic, and social environments. Policy influencers are informed and persuaded by coalitions that support or oppose changing the status quo. Empirical research examining policy influencers' contact with coalitions, as a social psychological exposure with health policy outcomes, can benefit from application of health communication theories. Accordingly, we analyzed responses to the 2014 Chronic Disease Prevention Survey for 184 Canadian policy influencers employed in provincial governments, municipalities, large workplaces, school boards, and the media. In addition to contact levels with coalitions, respondents' jurisdiction, organization, and ideology were analyzed as potential moderators. Calculating authority score centrality using network analysis, we determined health policy supporters to be more central in policy influencer networks, and theorized their potential to impact health policy public agenda setting via priming and framing processes. We discuss the implications of our results as presenting opportunities to more effectively promote health policy through priming and framing by coordinating coalitions across risk behaviors to advance a societal imperative for chronic disease prevention.

The adoption, implementation and maintenance of a school food policy in the Canadian Arctic: a retrospective case study.

With increasing childhood obesity rates and type 2 diabetes developing in younger age groups, many schools have initiated policies to support healthy eating and active living. Policy interventions can influence not only health behaviours in students but can also impact these behaviours beyond the school walls into the community. We articulate a policy story that emerged during the data collection phase of a study focused on building knowledge and capacity to support healthy eating and active living policy options in a small hamlet located in the Canadian Arctic. The policy processes of a local school food policy to address unhealthy eating are discussed. Through 14 interviews, decision makers, policy influencers and health practitioners described a policy process, retrospectively, including facilitators and barriers to adopting and implementing policy. A number of key activities facilitated the successful policy implementation process and the building of a critical mass to support healthy eating and active living in the community. A key contextual factor in school food policies in the Arctic is the influence of traditional (country) foods. This study is the first to provide an in-depth examination of the implementation of a food policy in a Canadian Arctic school. Recommendations are offered to inform intervention research and guide a food policy implementation process in a school environment facing similar issues.

Exploring Nutrition Labelling of Food and Beverages in Vending Machines in Canadian Recreational Sport Settings.

Purpose: To evaluate whether interpretive "health" labels placed in vending machines in recreation centres represented products' nutrient content when compared with provincial nutrition guidelines. Methods: A cross-sectional audit (November 2015 - April 2016) of 139 vending machines in recreation facilities found 525 foods and beverages in 17 machines labelled by vendors according to healthfulness. Product nutrient content was compared with provincial nutrition guideline criteria. Cross-tabulation and weighted Cohen's kappa evaluated agreement between vendor interpretive labels and guideline ranks. Descriptive statistics evaluated how mislabelled products deviated from recommended nutrient content. Mann-Whitney tests compared nutrient content of "healthy" and "unhealthy" labelled products. Results: Almost one-third of all products were mislabelled by vendors with 72% of those labelled healthier than their actual guideline rank. Energy, total fat, sugar, and sodium contents exceeded recommended levels in one-third to one-half of mislabelled products. Overall, products labelled healthy by vendors were significantly lower in energy, sodium, and fat compared with those labelled unhealthy; however, not for all food types (e.g., bars, fruit snacks, nuts). Conclusions: For certain product categories, vendor interpretive nutrition labels poorly represented products' nutrient content according to provincial nutrition guidelines. Dietitians may be a valuable resource to help implement nutrition guidelines to create credible interpretive product labelling systems.

Impact evaluation of a school-based oral health program: Kuwait National Program.

BACKGROUND: This study evaluated the relationship between enrolment in a school-based oral health prevention program (SOHP) and: 1) children's dental health status and oral health-related quality of life (OHRQoL), and 2) mothers' oral health (OH) knowledge, attitude, practice, and OHRQoL. METHODS: This cross-sectional study, in the Kuwait Capital, included 440 primary school children aged 11 to 12 years and their mothers. Participants were classified into two groups: SOHP and non-SOHP. The SOHP group had been enrolled in the prevention program for at least 3 years: children had twice-a-year applications of fluoride varnish and fissure sealants if needed; mothers had, at least, one oral health education session. The non-SOHP group had negative consents and had not been exposed to the prevention program activities. Dental examinations were performed at schools using portable dental units. Caries experience was determined using the decayed (D/d), missing (M/m), and filled (F/f) teeth (T/t)/surface (S/s) indices. Children's OHRQoL was assessed using a self-administered validated Child Perceptions Questionnaire 11-14 (CPQ11-14). Mothers' OH knowledge, attitude, practice, and OHRQoL were also assessed. After Bonferroni correction, a p-value of less than 0.05 was considered statistically significant for caries experience measures while a p-value of less than 0.013 was considered statistically significant for OHRQoL subscales and mothers' OH knowledge, attitude, practice, and OHRQoL. RESULTS: Mean (SD) DT/dt, DMFT/dmft and DMFS/dmfs were 1.41 (1.66), 2.35 (2.33), and 4.41 (5.86) for SOHP children, respectively. For non-SOHP children, the means were 2.61 (2.63), 3.56 (3.05), and 7.24 (7.78), respectively. The difference between the SOHP and non-SOHP was statistically significant (p <  0.001). Children enrolled in the program had a higher number of sealed and restored teeth. No significant differences were found in CPQ11-14 scores or subscale scores between the two groups. No significant difference in mothers' OH knowledge, attitude, practices or OHRQoL was found between SOHP and non-SOHP groups (P > 0.013). CONCLUSION: Enrolment in the SOHP prevention services was associated with a positive impact on children's caries level with no significant impact on mothers' knowledge, attitude, practice, or OHRQoL.

Reliability and validity of a novel tool to comprehensively assess food and beverage marketing in recreational sport settings.

BACKGROUND: Current methods for evaluating food marketing to children often study a single marketing channel or approach. As the World Health Organization urges the removal of unhealthy food marketing in children's settings, methods that comprehensively explore the exposure and power of food marketing within a setting from multiple marketing channels and approaches are needed. The purpose of this study was to test the inter-rater reliability and the validity of a novel settings-based food marketing audit tool. METHODS: The Food and beverage Marketing Assessment Tool for Settings (FoodMATS) was developed and its psychometric properties evaluated in five public recreation and sport facilities (sites) and subsequently used in 51 sites across Canada for a cross-sectional analysis of food marketing. Raters recorded the count of food marketing occasions, presence of child-targeted and sports-related marketing techniques, and the physical size of marketing occasions. Marketing occasions were classified by healthfulness. Inter-rater reliability was tested using Cohen's kappa (κ) and intra-class correlations (ICC). FoodMATS scores for each site were calculated using an algorithm that represented the theoretical impact of the marketing environment on food preferences, purchases, and consumption. Higher FoodMATS scores represented sites with higher exposure to, and more powerful (unhealthy, child-targeted, sports-related, large) food marketing. Validity of the scoring algorithm was tested through (1) Pearson's correlations between FoodMATS scores and facility sponsorship dollars, and (2) sequential multiple regression for predicting "Least Healthy" food sales from FoodMATS scores. RESULTS: Inter-rater reliability was very good to excellent (κ = 0.88-1.00, p < 0.001; ICC = 0.97, p < 0.001). There was a strong positive correlation between FoodMATS scores and food sponsorship dollars, after controlling for facility size (r = 0.86, p < 0.001). The FoodMATS score explained 14% of the variability in "Least Healthy" concession sales (p = 0.012) and 24% of the variability total concession and vending "Least Healthy" food sales (p = 0.003). CONCLUSIONS: FoodMATS has high inter-rater reliability and good validity. As the first validated tool to evaluate the exposure and power of food marketing in recreation facilities, the FoodMATS provides a novel means to comprehensively track changes in food marketing environments that can assist in developing and monitoring the impact of policies and interventions.

Food marketing in recreational sport settings in Canada: a cross-sectional audit in different policy environments using the Food and beverage Marketing Assessment Tool for Settings (FoodMATS).

BACKGROUND: Children's recreational sport settings typically sell energy dense, low nutrient products; however, it is unknown whether the same types of food and beverages are also marketed in these settings. Understanding food marketing in sports settings is important because the food industry often uses the promotion of physical activity to justify their products. This study aimed to document the 'exposure' and 'power' of food marketing present in public recreation facilities in Canada and assess differences between provinces with and without voluntary provincial nutrition guidelines for recreation facilities. METHODS: Food marketing was measured in 51 sites using the Food and beverage Marketing Assessment Tool for Settings (FoodMATS). The frequency and repetition ('exposure') of food marketing and the presence of select marketing techniques, including child-targeted, sports-related, size, and healthfulness ('power'), were assessed. Differences in 'exposure' and 'power' characteristics between sites in three guideline provinces (n = 34) and a non-guideline province (n = 17) were assessed using Pearson's Chi squared tests of homogeneity and Mann-Whitney U tests. RESULTS: Ninety-eight percent of sites had food marketing present. The frequency of food marketing per site did not differ between guideline and non-guideline provinces (median = 29; p = 0.576). Sites from guideline provinces had a significantly lower proportion of food marketing occasions that were "Least Healthy" (47.9%) than sites from the non-guideline province (73.5%; p < 0.001). Use of child-targeted and sports-related food marketing techniques was significantly higher in sites from guideline provinces (9.5% and 10.9%, respectively), than in the non-guideline province (1.9% and 4.5% respectively; p values < 0.001). It was more common in the non-guideline province to use child-targeted and sports-related techniques to promote "Least Healthy" items (100.0% and 68.4%, respectively), compared to the guideline provinces (59.3% and 52.0%, respectively). CONCLUSIONS: Recreation facilities are a source of children's exposure to unhealthy food marketing. Having voluntary provincial nutrition guidelines that recommend provision of healthier foods was not related to the frequency of food marketing in recreation facilities but was associated with less frequent marketing of unhealthy foods. Policy makers should provide explicit food marketing regulations that complement provincial nutrition guidelines to fulfill their ethical responsibility to protect children and the settings where children spend time.

Nurturing maternal health in the midst of difficult life circumstances: a qualitative study of women and providers connected to a community-based perinatal program.

BACKGROUND: Many socioecological and structural factors affect women's diets, physical activity, and her access and receptivity to perinatal care. We sought to explore women's and providers' perceptions and experiences of health in the pre- and post-natal period while facing difficult life circumstances, and accessing a community-based program partially funded by Canada Prenatal Nutrition Program (CPNP) in Alberta, Canada. METHODS: Following the principles of community-based participatory research, we conducted a focused ethnography that involved five focus groups with women (28 in total), eight one-on-one interviews with program providers, and observations of program activities. Data were analyzed through qualitative content analysis to inductively derive codes and categories. RESULTS: Women perceived eating healthy foods, taking prenatal vitamins, and being physically active as key health behaviours during pregnancy and postpartum. However, they were commonly coping with many difficult life circumstances, and faced health barriers for themselves and their babies. These barriers included pregnancy or birth complications, family and spousal issues, financial difficulties, and living rurally. On the other hand, women and providers identified many aspects of the community-based program that addressed the burden of adversities as enablers to better health during pregnancy and postpartum. CONCLUSION: Community-based programs have an important role in alleviating some of the burden of coping with difficult life circumstances for women. With such potential, community-based programs need to be well supported through policies. Policies supporting these programs, and ensuring adequate funding, can enable more equitable services to rural women and truly promote maternal health during pregnancy and postpartum.
