Exploring sales data during a healthy corner store intervention in Toronto: the Food Retail Environments Shaping Health (FRESH) project

The Bite of HOPE Small Food Business Development Program: a clinic-based culinary medicine program targeting local business owners

Culinary medicine is a popular approach to health promotion, but most programs focus on patient or provider-facing education. While laudable, these efforts do not represent the full potential for culinary medicine to impact community health. We describe a novel approach to culinary medicine at a federally qualified health center (FQHC), the HOPE Clinic: Bite of HOPE Small Food Business Development (SFBD) program. Describe the design and implementation of the Bite of HOPE SFBD program and examine initial response to the program through interviews and focus groups with past participants. The SFBD program aims to create healthy food outlets by supporting local small businesses with education, resources, and mentorship support. Former participants in the SFBD program were invited to participate in focus groups and interviews exploring their experience and perceived program impact. Three focus groups (n = 10) and nine in-depth interviews were conducted. Most participants were Black or Hispanic and all operated their businesses in the community surrounding HOPE Clinic. Five themes emerged from the data including perceived program purpose, program discovery, motivating factors to participation, perceived program impact, and suggestions for improvement. Participants expressed high satisfaction with the program and positive changes in both business development and personal eating habits. There is an opportunity to leverage the culinary medicine model to support local small food business and improve community health. The Bite of HOPE SFBD program offers an example of how clinic-based resources can expand into the surrounding environment.

Towards healthy food retail: An assessment of public health nutrition workforce capacity to work with stores

OBJECTIVE

This article aims to investigate the capacity of nutrition professionals to engage in food retail practice change to improve population diet.

METHODS

Convergent mixed method design was used that includes pre-interview surveys, in-depth interviews, and retrospective mapping of service provision. The study was conducted in organisations that provide a nutrition professional service to food retail stores in remote Australia. The study participants include 11 nutrition professionals and eight organisation representatives, including managers, organisation directors and policy officers. Systems-mapping and thematic analysis of the in-depth interviews were conducted using a capacity development framework. Descriptive analysis was applied to pre-interview survey and mapping data.

RESULTS

A gap between the aspirational work and current capacity of nutrition professionals to engage effectively with stores was identified. Engagement with stores to improve population health was valued by organisations. Dominance of the medical health model limited organisation strategic support for store work and created barriers. Key barriers included the limited access to training, decision-support tools, information, financial resources and organisational structures that directed store work.

CONCLUSIONS

Provision of adequate store-specific training, resources and organisational support may empower the nutrition professional workforce to be powerful leaders in co-design for healthy food retail.

IMPLICATIONS FOR PUBLIC HEALTH

Building capacity for this critical workforce to engage in food retail practice change must consider the influence of the broader health system and employer organisations and need for access to evidence-based decision-support tools.

Study protocol for CELLAR (COVID-related Eating Limitations and Latent dietary effects in the Atlantic Region): population-based observational study to monitor dietary intakes and purchasing during COVID-19 in four Atlantic Canadian provinces

INTRODUCTION

Poor diet is a leading preventable risk for the global burden of non-communicable disease. Robust measurement is needed to determine the effect of COVID-19 on dietary intakes and consumer purchasing, given the widespread changes to consumer food environments and economic precarity. The research objectives are as follows: (1) describe dietary intakes of foods, beverages and nutrients of concern during the COVID-19 pandemic; (2) quantify change in diet during COVID-19 as compared with prepandemic, previously captured in the provincial samples of the population-representative 2015 Canadian Community Health Survey-Nutrition and (3) examine how household purchasing practices predict dietary intakes during COVID-19.

METHODS AND ANALYSES

Observational study of diet, using a population-based stratified probability sampling strategy allocated via dual-frame (landline and cellphone) calls to random-digit dialled numbers, followed by age-sex group quotas. The base population comprises the four provinces of the Atlantic region of Canada, jurisdictions with an excess burden of pre-existing dietary risk, compared with the rest of Canada. Our aim is n=1000 to obtain reliable estimates at a regional level to describe intakes and compare with prepandemic baseline. Data collection entails 12 weeks participation: (1) enrolment with sociodemographics (key dietary risk predictors such as age, sex, gender, pre-COVID-19 income, employment, household composition, receipt of economic relief, rural residence); (2) two 24hour diet recalls using the online ASA-24 Canada 2018 tool; and (3) online uploads of household food purchase receipts over the 12 weeks enrolled. Participation incentives will be offered.

ETHICS AND DISSEMINATION

This research protocol received funding from the Canadian Institutes of Health Research (FRN VR5 172691) and ethics review approval from the Dalhousie University Research Ethics Board. Study protocol and instruments and a de-identified dataset will be made publicly available. We will submit the findings to peer-reviewed journals, as well as conferences geared towards scientific and decision-maker audiences.

Food Sales and Adult Weight Status: Results of a Cross-Sectional Study in England

Ecological studies often use supermarket location as a proxy measure of the food environment. In this study, we used data on sales at a leading mainstream supermarket chain to explore how area-level supermarket use is associated with overweight and obesity in English adults. Sales data were aggregated to local authority level and joined to a national dataset describing self-reported height and weight and fruit and vegetable consumption. Regression models showed a modest association between higher levels of unhealthy food sales relative to health food sales and increased odds of being overweight and obese. Although effect sizes were small, they persisted after adjustment for area-level deprivation. Supermarket sales data provide additional understanding in the study of food environments and their impact on increasing weight status. Future health policies should consider using ‘big data’ combined with other research methods to address the increasing consumption of unhealthy and highly processed foods.

Perceived barriers and facilitators to participating in the North Carolina Healthy Food Small Retailer Program: a mixed-methods examination considering investment effectiveness

OBJECTIVE

The North Carolina Legislature appropriated funds in 2016-2019 for the Healthy Food Small Retailer Program (HFSRP), providing small retailers located in food deserts with equipment to stock nutrient-dense foods and beverages. The study aimed to: (1) examine factors facilitating and constraining implementation of, and participation in, the HFSRP from the perspective of storeowners and (2) measure and evaluate the impact and effectiveness of investment in the HFSRP.

DESIGN

The current analysis uses both qualitative and quantitative assessments of storeowner perceptions and store outcomes, as well as two innovative measures of policy investment effectiveness. Qualitative semi-structured interviews and descriptive quantitative approaches, including monthly financial reports and activity forms, and end-of-programme evaluations were collected from participating HFSRP storeowners.

SETTING

Eight corner stores in North Carolina that participated in the two cohorts (2016-2018; 2017-2019) of the HFSRP.

PARTICIPANTS

Owners of corner stores participating in the HFSRP.

RESULTS

All storeowners reported that the HFSRP benefitted their stores. In addition, the HFSRP had a positive impact on sales across each category of healthy food products. Storeowners reported that benefits would be enhanced with adjustments to programme administration and support. Specific suggestions included additional information regarding which healthy foods and beverages to stock; inventory management; handling of perishable produce; product display; modified reporting requirements and a more efficient process of delivering and maintaining equipment.

CONCLUSIONS

All storeowners reported several benefits of the HFSRP and would recommend that other storeowners participate. The barriers and challenges they reported inform potential approaches to ensuring success and sustainability of the HFSRP and similar initiatives underway in other jurisdictions.

Nutrition Interventions in Low-Income Rural and Urban Retail Environments: A Systematic Review

BACKGROUND

Nutrition interventions promoting healthy food choices aim to address health challenges of residents in low-income environments. Research about the effectiveness of nutrition interventions in low-income populations is limited, particularly for those in rural areas. Behavioral economics (BE) strategies demonstrate effectiveness for improving eating behaviors in some settings. However, the efficacy of BE interventions in retail food stores serving low-income populations residing in rural and urban geographies is nascent.

OBJECTIVE

This systematic literature review aims to identify and compare nutrition interventions implemented in rural and urban low-income retail food stores, including BE strategies when applied.

METHODS

This review was conducted according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Reviewers searched five databases for peer-reviewed publications from October 2010 to October 2019. Included studies implemented a nutrition intervention in low-income retail food stores and provided a quantitative outcome evaluation with results separated by rural and urban geography. BE interventions were analyzed based on the MINDSPACE framework for behavior change.

RESULTS

Forty-six separate publications (n = 20 rural, n = 26 urban) in the United States, Canada, Europe, New Zealand, and Australia were included. Researchers independently rated publications as low risk of bias (n = 4), moderate (n = 18), or high risk of bias (n = 24) using the Quality Assessment Tool for Quantitative Studies. Studies (n = 18) demonstrated positive outcomes for customer purchases, store sales, or participant intake of targeted healthy foods. Overall, most effective interventions included point-of-purchase signage (n = 16) and product placement strategies (n = 4 urban). Rural studies included financial incentives combined with participant education (n = 2) and incorporated culturally appropriate messengers and/or symbols (n = 5) to improve healthy food purchases and intake.

CONCLUSIONS

Improved research quality and tailored evidence-based interventions, including BE strategies, are necessary in retail food environments to promote healthy eating behaviors in low-income populations.

A 'whole systems' approach to reduce sugar-sweetened beverage consumption: issues for global health promotion through a small island lens

Reducing sugar-sweetened beverage (SSB) consumption is a prominent strategy to reduce sugar intake and non-communicable disease (NCD) risk worldwide. Recommended measures encompass policy, environmental modification, health literacy, reformulation and taxation. This commentary draws from an intervention to reduce SSB consumption in a remote, rural context with high intake and under-developed alternatives and health literacy. The island of St Helena introduced SSB taxation from 2014, yet impact appeared limited. In 2018, supply and demand measures for substitute products were developed, alongside a taxation increase. Preliminary data indicate a shift away from SSB towards non-sugar beverages (artificially sweetened beverages (ASB) and tap water). Issues for global health promotion include the specific manifestation of social and commercial determinants of health in remote and rural contexts, integrated multifaceted strategies to provide supporting conditions for policies such as SSB taxation to deliver impact, and the role of ASB to reduce SSB in high consumption contexts.

Fruit and Vegetable Purchases in Farmer's Market Stands: Analysing Survey and Sales Data

Farmers' market implementation holds promise for increasing access to healthy foods. Although rarely measured, purchase data constitute an intermediate outcome between food environment and actual consumption. In a study conducted with two seasonal Fruits and Vegetables (FV) stands in a disadvantaged area of Montréal (Canada), we analysed how accessibility, perception, and mobility-related factors were associated with FV purchase. This analysis uses a novel measure of FV purchasing practices based on sales data obtained from a mobile application. A 2016 survey collected information on markets' physical access, perceived access to FV in the neighbourhood, usual FV consumption and purchases. Multivariate models were used to analyse three purchasing practice indicators: number of FV portions, FV variety and expenditures. Average shoppers purchased 12 FV portions of three distinct varieties and spent 5$. Shoppers stopping at the market on their usual travel route spent less (p = 0.11), bought fewer portions (p = 0.03) and a lesser FV variety (p < 0.01). FV stands may complement FV dietary intake. Individuals for whom the market is on their usual travel route might make more frequent visits and, therefore, smaller purchases. The novel data collection method allowed analysis of multiple purchase variables, is precise and easy to apply at unconventional points of sales and could be transposed elsewhere.

A Systematic Review of the Effect of Retail Food Environment Interventions on Diet and Health with a Focus on the Enabling Role of Public Policies

PURPOSE OF REVIEW

Update the state of evidence on the effectiveness of retail food environment interventions in influencing diet and explore the underlying role of public policy, through a systematic review of population-level interventions to promote health in the retail food environment, including community and consumer environments. Diet-related outcomes included purchasing, dietary intakes, diet quality, and health including weight. We coded studies for enabling public policy levers underpinning the intervention, using two widely used conceptual frameworks.

RECENT FINDINGS

Of 86 articles (1974-2018), the majority (58 articles, 67%) showed at least one positive effect on diet. Thirteen articles (15%) discussed natural experiments, 27 articles (31%) used a design involving comparison groups including 23 articles (27%) specifically describing randomized controlled trials, and 46 (53%) were quasi-experimental (cross-sectional) evaluations. Across the "4Ps" of marketing (product, promotion, placement, and price), promotion comprised the greatest proportion of intervention strategies, especially in earlier literature (pre-2008). Few studies combined geographic access interventions with 4P strategies, and few used robust dietary intake assessments. Behavior change communication remains an intervention mainstay, but recent work has also incorporated environmental and social planning, and fiscal strategies. More recent interventions were multi-component. The retail food environment intervention literature continues to grow and has become more robust overall, with clearer evidence of the effect of interventions on diet-related outcomes, including consumer purchasing, dietary intakes, and health. There is still much scope for development in the field. Attention to enabling public policy could help to strengthen intervention implementation and evaluation in the retail food environment.

Novel Sales Tracking Method to Evaluate a Healthy Corner Store Intervention

This article describes a Supplemental Nutrition Assistance Program-Education-funded (SNAP-Ed) healthy corner store intervention and novel evaluation method for tracking sales of promoted foods in two corner stores in North Carolina. The healthy corner store intervention was designed to encourage the purchase of healthy foods among SNAP participants. Stickers were placed on eligible foods to highlight healthy options as well as assist with tracking the sales of those products. Store staff removed the sticker and placed it on a tracking sheet that recorded the date, number of healthy foods purchased, whether the purchased item(s) contained a fruit or vegetable, and the type of payment. Storeowners were interested in participating and remained engaged throughout the program; however, there were challenges with fidelity to the intervention and its evaluation using the sticker method to track sales. Additional research on methods for evaluating healthy retail interventions that are simple, low cost, and feasible for retailers that do not have electronic sales data is needed.
