In this paper, we examined whether there are inequalities in access to food retail (by type and healthiness) across local government areas (LGA) in Greater Melbourne and by LGA grouped based on their distance from the central business district and Growth Area designation. We also examined whether these inequalities persisted over time.

This is a secondary analysis of a repeated cross-sectional census of food outlets collected at four time points (2008, 2012, 2014 and 2016) across 31 LGA. Using Geographical Information Systems, we present a spatial analysis of food retail environments in Melbourne, Australia, at these four times over eight years.

Greater Melbourne, Australia.

31 LGA in Greater Melbourne.

Findings show significant inequalities in access to healthy food retail persisting over time at the LGA level. Residents in lower density urban growth areas had the least access to healthy food retail. Unhealthy food retail was comparatively more accessible, with a temporal trend indicating increased accessibility over time in urban growth areas only.

Accessibility to food outlets, particularly healthy food outlets and supermarkets, in Greater Melbourne is not equal. To identify and address health inequalities associated with rapid urban growth, further understanding of how people interact with the food environment needs to be explored.

To explore changes in plant-based and meat product sales during and after implementation of a multi-component in-store intervention implemented by a major UK food retailer. Secondary objectives included exploring differences by store format and area affluence.

The intervention increased the visibility, accessibility, affordability and availability of a selection of plant-based products. Unit sales of plant-based and meat products during the intervention (January 2021) were compared with pre- (November 2020) and post-intervention (February and March 2021). Non-meat product sales were assessed as a control. Negative binomial mixed models were used to explore sales changes and differences by store format or affluence.

The intervention was applied in a real-world supermarket setting during Veganuary.

Stores that applied the full intervention (n 154) were included for analysis. Weekly sales data for each store were obtained from the retailer.

Average weekly unit sales of plant-based products increased significantly (57 %) during the intervention period (incidence rate ratio (IRR) 1·52 (95 % CI1·51, 1·55)). Plant-based product sales decreased post-intervention but remained 15 % higher than pre-intervention (IRR 1·13 (95 % CI 1·12, 1·14)). There was no significant change in meat sales according to time period. The increase in plant-based product sales was greatest at superstores (58 %), especially those located in below average affluence areas (64 %).

Results suggest that increasing visibility, accessibility, affordability and availability of plant-based products led to increased sales, with evidence of lasting effects. No significant changes in meat sales were observed. Variation according to store format and area affluence indicates targeted intervention approaches are needed.

To estimate the prevalence of online grocery shopping in a nationally representative sample and describe demographic correlates with online grocery shopping.

The Nielsen COVID-19 Shopper Behavior Survey was administered to a subset of Nielsen National Consumer Panel participants in July 2020. We used survey weighted-multivariable logistic regression to examine demographic correlates of having ever online grocery shopped.

Online survey.

18 598 Nielsen National Consumer Panel participants in the USA.

Thirty-nine percent of respondents had purchased groceries online, and among prior purchasers, 89 % indicated that they would continue to online grocery shop in the next month. Canned/packaged foods were the most shopped for grocery category online, followed by beverages, fresh foods and lastly frozen foods. In adjusted analyses, younger respondents (39 years or less) were more likely (47 %) to have ever shopped for groceries online than older age groups (40–54 years, 55–64 years and 65+ years) (29 %, 22 % and 23 %, respectively, all P < 0·001). Those with greater than a college degree were more likely to have ever grocery shopped online (45 %) than respondents with some college education (39 %) and with a high school education or less (32 %) (both P < 0·001). Having children, having a higher income and experiencing food insecurity, particularly among higher income food-insecure households, were also associated with a higher probability of prior online grocery shopping.

The COVID-19 pandemic accelerated the transition to online grocery shopping. Future research should explore the nutrition implications of online grocery shopping.

To evaluate changes in the retail food environment profile in a Brazilian metropolis over a 10-year period.

An ecological study was conducted in the city of Belo Horizonte, Minas Gerais, Brazil. The addresses of formal food establishments were geocoded and classified according to their sold-food profile. Density changes were analysed according to neighbourhood, population size, income level and geospatial distribution.

Totally, 468 neighbourhoods in the city of Belo Horizonte, Minas Gerais, Brazil.

Totally, 83 752 formal food establishments registered for operation in any one or more of those years: 2008, 2011, 2015 and 2018.

There was an increase in unhealthy establishments (154 %), followed by mixed (51 %) and healthy establishments (32 %), during the period evaluated, in addition to an increase in density according to income categories. There was a higher proportion of unhealthy establishments in relation to healthy establishments, indicating worsening of the community food environment over time.

Over the course of 10 years, changes in the neighbourhood’s food environment were unfavourable for adequate access to healthy foods in lower-income neighbourhoods. The findings reinforce the need for interventions aimed at increasing the availability of businesses that offer healthy food in the city.

‘Food deserts’ and ‘food swamps’ are food retail environment typologies associated with unhealthy diet and obesity. The current study aimed to identify more complex food retail environment typologies and examine temporal trends.

Measures of food retail environment accessibility and relative healthy food availability were defined for small areas (SA2s) of Melbourne, Australia, from a census of food outlets operating in 2008, 2012, 2014 and 2016. SA2s were classified into typologies using a two-stage approach: (1) SA2s were sorted into twenty clusters according to accessibility and availability and (2) clusters were grouped using evidence-based thresholds.

The current study was set in Melbourne, the capital city of the state of Victoria, Australia.

Food retail environments in 301 small areas (Statistical Area 2) located in Melbourne in 2008, 2012, 2014 and 2016.

Six typologies were identified based on access (low, moderate and high) and healthy food availability including one where zero food outlets were present. Over the study period, SA2s experienced an overall increase in accessibility and healthiness. Distribution of typologies varied by geographic location and area-level socio-economic position.

Multiple typologies with contrasting access and healthiness measures exist within Melbourne and these continue to change over time, and the majority of SA2s were dominated by the presence of unhealthy relative to healthy outlets, with SA2s experiencing growth and disadvantage having the lowest access and to a greater proportion of unhealthy outlets.

To test the feasibility of implementing and evaluating a healthier checkout pilot study in a convenience store chain.

A quasi-experimental study was conducted comparing a 3-month ‘healthier checkouts’ intervention in ten convenience stores which stocked eight healthier items in the checkout space and ten comparison stores assigned to continue stocking their current checkout space product mix. All aspects of the intervention were implemented by the retailer. The research team conducted in-person fidelity checks to assess implementation. Sales data were collected from the retailer in order to compare mean baseline to intervention sales of the eight healthier items in intervention and comparison groups while controlling for overall store sales.

Twenty convenience stores in New Hampshire.

The increases in sales of healthier items between the baseline and intervention periods among the intervention and comparison stores were not statistically significant; however, the overall pattern of the results showed promising changes that should be expanded on in future studies. Intervention fidelity checks indicated that results may have been attenuated by variability in intervention implementation.

This study advances the evidence for effective promotion of healthier food purchases in the convenience store chain setting and adds to the current literature on retail checkout space interventions. Additional research is needed to confirm and expand these results.

To rigorously develop a tool which enables rapid yet comprehensive appraisal of the consumer food retail environment and provision of real-time feedback to store managers and owners, based on the ‘4Ps’ principles of marketing.

Multi-stage iterative approach including (1) Systematic literature review; (2) Stakeholder consultation; (3) Assessment of existing tools against identified needs; (4) Tool development; (5) Pilot testing and (6) Transition of tool to mobile application (the Store Scout app).

Northern Territory, Australia.

Nine remote Aboriginal community food stores; public health nutritionists, retailers, store board directors, Aboriginal community members, government representatives.

Forty-seven existing tools and thirty-four stakeholder interviews informed the development of the current instrument, which comprised: (1) seven product categories (Fruit & Vegetables, Drinks, Snack Foods, Meals & Convenience Foods, Meat & Seafood, Dairy & Eggs, Breads & Cereals) across the ‘4Ps’ (Product, Placement, Price, Promotion); (2) Store manager questions about context and perceived importance of key principles about the store environment and (3) a scoring and feedback component. The tool was considered feasible and acceptable by all testers.

The developed tool addresses an unmet need to measure the consumer food retail environment across all 4Ps whilst also incorporating manager perspectives and immediate feedback. Our objectives of developing a comprehensive, feasible and acceptable instrument were achieved during pilot testing. The tool will support implementation of best practice within stores to encourage healthy food choices and has potential for broad application in retail settings locally and internationally, as well as for research purposes.

Our objectives were to explore attitudes regarding food retail policy and government regulation among managers of small food stores and examine whether manager views changed due to the 2014 Minneapolis Staple Foods Ordinance, a city policy requiring retailers to stock specific healthy products.

Manager interviewer-administered surveys were used to assess views on food retail policy four times from 2014 to 2017. We examined baseline views across manager and store and neighbourhood characteristics using cross-sectional regression analyses and examined changes over time using mixed regression models. In 2017, open-ended survey questions asked about manager insights on the Minneapolis Staple Foods Ordinance.

Minneapolis, MN, where the ordinance was enacted, and St. Paul, MN, a control community, USA.

Managers from 147 small food retail stores.

At baseline, 48 % of managers were likely to support a policy requiring stores to stock healthy foods/beverages, 67·5 % of managers were likely to support voluntary programmes to help retailers stock healthy foods and 23·7 % agreed government regulation of business is good/necessary. There was a significant increase in overall support for food retail policies and voluntary programmes from 2014 to 2017 (P < 0·01); however, neither increase differed by city, suggesting no differential impact from the ordinance. Minneapolis store managers reported some challenges with ordinance compliance and offered suggestions for how local government could provide support.

Findings suggest that managers of small food retail stores are becoming increasingly amenable to healthy food policies; yet, challenges need to be addressed to ensure healthy food is available to all customers.

Commercially available business (CAB) datasets for food environments have been investigated for error in large urban contexts and some rural areas, but there is a relative dearth of literature that reports error across regions of variable rurality. The objective of the current study was to assess the validity of a CAB dataset using a government dataset at the provincial scale.

A ground-truthed dataset provided by the government of Newfoundland and Labrador (NL) was used to assess a popular commercial dataset. Concordance, sensitivity, positive-predictive value (PPV) and geocoding errors were calculated. Measures were stratified by store types and rurality to investigate any association between these variables and database accuracy.

NL, Canada.

The current analysis used store-level (ecological) data.

Of 1125 stores, there were 380 stores that existed in both datasets and were considered true-positive stores. The mean positional error between a ground-truthed and test point was 17·72 km. When compared with the provincial dataset of businesses, grocery stores had the greatest agreement, sensitivity = 0·64, PPV = 0·60 and concordance = 0·45. Gas stations had the least agreement, sensitivity = 0·26, PPV = 0·32 and concordance = 0·17. Only 4 % of commercial data points in rural areas matched every criterion examined.

The commercial dataset exhibits a low level of agreement with the ground-truthed provincial data. Particularly retailers in rural areas or belonging to the gas station category suffered from misclassification and/or geocoding errors. Taken together, the commercial dataset is differentially representative of the ground-truthed reality based on store-type and rurality/urbanity.

Food environments may be contributing to the rapid increase in obesity occurring in most Latin American (LA) countries. The present study reviews literature from LA that (i) describes the food environment and policies targeting the food environment (FEP); and (ii) analytic studies that investigate associations between the FEP and dietary behaviours, overweight/obesity and obesity related chronic diseases. We focus on six dimensions of the FEP: food retail, provision, labelling, marketing, price and composition.

Systematic literature review. Three databases (Web of Science, SciELO, LILACS) were searched, from 1 January 1999 up to July 2017. Two authors independently selected the studies. A narrative synthesis was used to summarize, integrate and interpret findings.

Studies conducted in LA countries.

The search yielded 2695 articles of which eighty-four met inclusion criteria.

Most studies were descriptive and came from Brazil (61 %), followed by Mexico (18 %) and Guatemala (6 %). Studies were focused primarily on retail/provision (n 27), marketing (n 16) and labelling (n 15). Consistent associations between availability of fruit and vegetable markets and higher consumption of fruits and vegetables were found in cross-sectional studies. Health claims in food packaging were prevalent and mostly misleading. There was widespread use of marketing strategies for unhealthy foods aimed at children. Food prices were lower for processed relative to fresh foods. Some studies documented high sodium in industrially processed foods.

Gaps in knowledge remain regarding policy evaluations, longitudinal food retail studies, impacts of food price on diet and effects of digital marketing on diet/health.

We examined differences in consumer-level characteristics and structural resources and capabilities of small and non-traditional food retailers (i.e. corner stores, gas-marts, pharmacies, dollar stores) by racial segregation of store neighbourhood and corporate status (corporate/franchise- v. independently owned).

Observational store assessments and manager surveys were used to examine availability-, affordability- and marketing-related characteristics experienced by consumers as well as store resources (e.g. access to distributors) and perceived capabilities for healthful changes (e.g. reduce pricing on healthy foods). Cross-sectional regression analyses of store and manager data based on neighbourhood segregation and store corporate status were conducted.

Small and non-traditional food stores in Minneapolis and St. Paul, MN, USA.

One hundred and thirty-nine stores; seventy-eight managers.

Several consumer- and structural-level differences occurred by corporate status, independent of residential segregation. Compared with independently owned stores, corporate/franchise-owned stores were more likely to: not offer fresh produce; when offered, receive produce via direct delivery and charge higher prices; promote unhealthier consumer purchases; and have managers that perceived greater difficulty in making healthful changes (P≤0·05). Only two significant differences were identified by residential racial segregation. Stores in predominantly people of colour communities (<30 % non-Hispanic White) had less availability of fresh fruit and less promotion of unhealthy impulse buys relative to stores in predominantly White communities (P≤0·05).

Corporate status appears to be a relevant determinant of the consumer-level food environment of small and non-traditional stores. Policies and interventions aimed at making these settings healthier may need to consider multiple social determinants to enable successful implementation.

Little is known about customer purchases of foods and beverages from small and non-traditional food retailers (i.e. corner stores, gas-marts, dollar stores and pharmacies). The present study aimed to: (i) describe customer characteristics, shopping frequency and reasons for shopping at small and non-traditional food retailers; and (ii) describe food/beverage purchases and their nutritional quality, including differences across store type.

Data were collected through customer intercept interviews. Nutritional quality of food/beverage purchases was analysed; a Healthy Eating Index-2010 (HEI-2010) score for purchases was created by aggregating participant purchases at each store.

Small and non-traditional food stores that were not WIC-authorized in Minneapolis and St. Paul, MN, USA.

Customers (n 661) from 105 food retailers.

Among participants, 29 % shopped at the store at least once daily; an additional 44 % shopped there at least once weekly. Most participants (74 %) cited convenient location as the primary draw to the store. Customers purchased a median of 2262 kJ (540 kcal), which varied by store type (P=0·04). The amount of added sugar far surpassed national dietary recommendations. At dollar stores, participants purchased a median of 5302 kJ (1266 kcal) for a median value of $US 2·89. Sugar-sweetened beverages were the most common purchase. The mean HEI-2010 score across all stores was 36·4.

Small and non-traditional food stores contribute to the urban food environment. Given the poor nutritional quality of purchases, findings support the need for interventions that address customer decision making in these stores.

Little is known about the practices for stocking and procuring healthy food in non-traditional food retailers (e.g. gas-marts, pharmacies). The present study aimed to: (i) compare availability of healthy food items across small food store types; and (ii) examine owner/manager perceptions and stocking practices for healthy food across store types.

Descriptive analyses were conducted among corner/small grocery stores, gas-marts, pharmacies and dollar stores. Data from store inventories were used to examine availability of twelve healthy food types and an overall healthy food supply score. Interviews with managers assessed stocking practices and profitability.

Small stores in Minneapolis and St. Paul, MN, USA, not participating in the Special Supplemental Nutrition Program for Women, Infants, and Children.

One hundred and nineteen small food retailers and seventy-one store managers.

Availability of specific items varied across store type. Only corner/small grocery stores commonly sold fresh vegetables (63 % v. 8 % of gas-marts, 0 % of dollar stores and 23 % of pharmacies). More than half of managers stocking produce relied on cash-and-carry practices to stock fresh fruit (53 %) and vegetables (55 %), instead of direct store delivery. Most healthy foods were perceived by managers to have at least average profitability.

Interventions to improve healthy food offerings in small stores should consider the diverse environments, stocking practices and supply mechanisms of small stores, particularly non-traditional food retailers. Improvements may require technical support, customer engagement and innovative distribution practices.

In the context of the nutrition transition and associated changes in the food retail sector, to examine the socio-economic characteristics and motivations of shoppers using different retail formats (large supermarkets (LSM), medium-sized supermarkets (MSM) or traditional outlets) in Tunisia.

Cross-sectional survey (2006). Socio-economic status, type of food retailer and motivations data were collected during house visits. Associations between socio-economic factors and type of retailer were assessed by multinomial regression; correspondence analysis was used to analyse declared motivations.

Peri-urban area around Tunis, Tunisia, North Africa.

Clustered random sample of 724 households.

One-third of the households used LSM, two-thirds used either type of supermarket, but less than 5 % used supermarkets only. Those who shopped for food at supermarkets were of higher socio-economic status; those who used LSM were much wealthier, more often had a steady income or owned a credit card, while MSM users were more urban and had a higher level of education. Most households still frequently used traditional outlets, mostly their neighbourhood grocer. Reasons given for shopping at the different retailers were most markedly leisure for LSM, while for the neighbourhood grocer the reasons were fidelity, proximity and availability of credit (the latter even more for lower-income customers).

The results pertain to the transition in food shopping practices in a south Mediterranean country; they should be considered in the context of growing inequalities in health linked to the nutritional transition, as they differentiate use and motivations for the choice of supermarkets v. traditional food retailers according to socio-economic status.
