Over recent decades, the commercial ultra-processed food industry has grown, making snacks high in energy, added sugar, saturated fat and sodium affordable and accessible to consumers. Dietary patterns high in ultra-processed snacks are concerning as this can result in negative health outcomes. This study aims to provide insight on available snack products in South African supermarkets, and the marketing thereof, which can be used to support policy development aimed at improving the healthfulness of the food supply and consumption patterns.

This was an observational cross-sectional, mixed-method study.

Secondary data from six major supermarket chains (eight stores) in three different suburbs in Cape Town, South Africa was analysed to evaluate the nutritional composition of snack products (n=3837). The same eight supermarkets were revisited to obtain information on marketing via an observational checklist. Qualitative interviews were also conducted with store managers.

Majority (89%) of the products assessed either contained non-sugar sweeteners or were high in sugar, saturated fat, or sodium. These snack items that are high in nutrients of concern to limit were available at checkout areas in all stores, were found in high traffic areas and several in-store promotional strategies such as branded displays, special offers and combo-deals were commonly found.

The current South African supermarket environment encourages consumers to purchase unhealthy snacks. Most snacks assessed in this study cannot be recommended for regular consumption due to the nutritional composition being high in nutrients linked to poor health outcomes. There is a need for regulation of the in-store marketing of unhealthy snacks in South Africa. Retail settings are potential intervention points for limiting exposure to these unhealthy products.

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.

This review aimed to (i) synthesise evidence of the impact of publicly procured school meals programmes on nutritional outcomes of children/adolescents (5–18 years) in sub-Saharan Africa and (ii) identify challenges and facilitators to implementing effective school meals programmes.

Mixed-methods systematic review (n 7 databases). Nutritional outcomes assessed were anthropometrics (underweight, stunting, wasting, overweight/obesity), micronutrient deficiencies, food consumed and food environment. Qualitative findings were coded using a nine-step school food system framework: production of food, wholesale and trading, transportation and storage, processing and distribution, food preparation, distribution to students, student stakeholders, community involvement and infrastructure support.

Sub-Saharan Africa.

Children/adolescents (5–18 years), parents, school personnel and government officials.

Thirty-three studies (twenty-six qualitative, seven quantitative) from nine sub-Saharan African countries were included. Six studies found a positive impact of publicly procured school meals programmes on nutritional outcomes (wasting (n 1), stunting (n 3), underweight (n 1), vitamin A intake (n 1) and dietary diversity (n 1)). Fifty-three implementation challenges were identified, particularly during food preparation (e.g. training, payment), distribution to students (e.g. meal quantity/quality/diversity, utensils) and infrastructure support (e.g. funding, monitoring, coordination). Implementation facilitators were identified (n 37) across processing and distribution (e.g. programme coordination), student stakeholders (e.g. food preferences, reduced stigma) and community involvement (e.g. engagement, positive perceptions). Included policy recommendations targeted wholesale and trading, food preparation, student stakeholders and infrastructure support in nine, fifteen and twenty-five studies, respectively.

As many challenges remain, strengthening implementation (and therefore the nutritional impact) of school meals programmes in sub-Saharan Africa requires bold commitment and improved coordination at multiple levels of governance.

Evaluate the 5-year changes in the consumers’ food environment in the area of a health promotion service in Brazilian primary health care. Our hypothesis is that the consumers’ food environment in the areas with primary healthcare services has changes that may favour healthy eating habits over time.

Longitudinal study.

The territory around the primary healthcare services in Belo Horizonte, Minas Gerais, Brazil.

All food stores and open-air food markets that sell fruits and vegetables around the primary healthcare services in 2013 (n 272) and in 2018 (n 265).

Fruit diversity increased by 13·4 % (P < 0·001) and vegetables variety and quality by 16·1 % (P = 0·003) and 12·5 % (P < 0·001), respectively. Corn snacks showed an increase in availability (13·5 %; P = 0·002). The increase in advertising was observed for fruits and vegetables (34·6 %; P < 0·001) and ultra-processed foods (47·6 %; P < 0·001). Supermarkets showed an increase in the Healthy Food Store Index (three points; P < 0·001), while fruits and vegetables stores showed a decrease of one point in the index (P < 0·001).

The unequal changes in the consumers’ food environment according to the food stores types demonstrate the importance of food supply policies that promote a healthy environment and favour the maintenance of traditional healthy food retailers.

Healthy food retail programmes (HFRP) in the USA generally aim to increase healthy foods access to improve diet quality and health, yet the impact is mixed. These programmes primarily target adults, even though adolescents frequently and independently visit stores to purchase snacks. This study’s aims are to explore successes and challenges of implementing HFRP (Aim 1) and examine how HFRP can be tailored to adolescents (Aim 2).

One-time, virtual, semi-structured interviews with individuals who were involved in a HFRP, followed by a socio-demographic characteristics survey. Interviews were designed based on the RE-AIM framework and the Hexagon Tool and analysed using Braun and Clark’s (2006) thematic analysis approach. Descriptive statistics were used to summarise participants’ socio-demographic characteristics.

New York City (NYC).

Adults (18 years or older) who have designed, implemented and/or evaluated an HFRP in NYC and speak/understand English (n 21).

Aim 1: For successes, strategies to build relationships with the community were most discussed. Regarding challenges, securing reliable funding was the hardest to overcome. Suggested solutions included designing profitable HFRP, targeting shortcomings in food distribution systems and increasing consumer demand. Aim 2: Most participants had not considered adolescents in previous HFRP but suggested involving youth in developing HFRP to encourage youth-driven solutions and promote youth advocacy.

Future HFRP should focus on activities that help store owners purchase affordable healthy foods from distributors, which translates to affordability for customers. Federal and local policies can assist by funding complementary programmes. Additionally, adolescents should be considered in these efforts.

We aimed to understand what influences parents’ purchasing behaviours when shopping for groceries online and potential ways to improve the healthiness of online grocery platforms.

We conducted semi-structured interviews, guided by the Marketing Mix framework. Reflexive thematic analysis was used to analyse data.

Online interviews were conducted with primary grocery shoppers.

Parents (n 14) or caregivers (n 2) using online grocery platforms at least every 2 weeks.

Most participants perceived purchasing healthy food when shopping for groceries online to be more challenging compared to in physical stores. They expressed concerns about the prominence of online marketing for unhealthy food. Participants from lower socio-economic backgrounds often depended on online supermarket catalogues to find price promotions, but healthy options at discounted prices were limited. Across socio-economic groups, fresh items like meat and fruit were preferred to be purchased instore due to concerns about online food quality.

Participants believed online grocery platforms should make healthy foods more affordable and supported regulations on supermarket retailers to promote healthy options and limit unhealthy food promotion online.

Participants had varied experiences with online grocery shopping, with both positive and negative aspects. Efforts to improve population diets need to include mechanisms to create health-enabling online grocery retail platforms. Government interventions to restrict marketing of unhealthy foods and promote marketing of healthy options on these platforms warrant investigation.

To characterise the food environment of Dutch small and medium-sized enterprises (SMEs), encompassing physical, sociocultural, economic and policy features and to explore variations within SMEs according to company characteristics (number of employees, location of work and presence of worksite cafeteria).

Online cross-sectional survey study of a representative Dutch SME sample by a panel agency.

Dutch SMEs.

Three hundred and fifteen employees of Dutch SMEs responsible for food and drink in their company.

Most SMEs did not have a worksite cafeteria, no provision of fruits or vegetables, and did not offer discounts on food or drinks. The food environment of these SMEs varied significantly based on company characteristics. For example, SMEs with a worksite cafeteria were significantly more likely to have fruits (OR = 8·76, 95 % CI (4·50, 17·06)), vegetables (OR = 10·29, 95 % CI (5·49, 19·31)) and company food policies (OR = 5·04, 95 % CI (2·08, 12·20)) than SMEs without. Additionally, SMEs with ≥ 50 employees were more likely to have fruits (OR = 2·39, 95 % CI (1·42, 4·03)), vegetables (OR = 1·89, 95 % CI (1·04, 3·46)) and company food policies (OR = 2·82, 95 % CI (1·09, 7·29) than SMEs with < 50 employees. Moreover, having a worksite cafeteria (B = 0·23, 95 % CI (0·08, 0·38)) and employees working mostly on-site (B = 0·14, 95 % CI (0·01, 0·28)) were associated with stronger social norms of healthy and sustainable eating at work compared to SMEs without a worksite cafeteria and working mostly off-site.

In SMEs, an overall comprehensive picture of the food environment points to its limited active encouragement of healthy food choices, particularly so in small SMEs without a worksite cafeteria. Company characteristics strongly influence SME food environments and should be considered when developing interventions improving SME workplace food environments.

To assess the selection of foods and beverages in children’s sports arenas in Norway.

A cross-sectional study design with a digital questionnaire was used. Descriptive statistics were used to present the results. Moreover, Pearson’s χ2 tests examined the factors that could aid in distinguishing clubs with healthy or unhealthy consumables.

Children’s sports clubs in Norway.

Representatives from 301 children’s sports clubs in Norway answered the questionnaire between September and November 2021.

In total, 89·4% of the participating sports clubs (n 301) offered soda drinks with sugar. Most of the sports clubs (88 %) reported to offer batter-based cakes such as pancakes and waffles and 63·8 % offered cakes. Furthermore, 47·5% sold hot dishes with processed meat, such as hamburgers and hot dogs. More than 80% of the sports clubs offered sweets and snacks, while 44·5% did not offer fruits, vegetables and/or berries. Notably, the important factors that distinguished sports clubs with healthier food selections from those with unhealthier selections were the presence of guidelines for the food offered and purchase agreements with food suppliers.

Educational, governmental guidelines for the promotion of healthy eating and establishing agreements with suppliers of healthier foods could help to overcome barriers to unhealthy food selection.

It is unknown how well menu labelling schemes that enforce the display of kilojoule (kJ) labelling at point-of-sale have been implemented on online food delivery (OFD) services in Australia. This study aimed to examine the prevalence of kJ labelling on the online menus of large food outlets with more than twenty locations in the state or fifty locations nationally. A secondary aim was to evaluate the nutritional quality of menu items on OFD from mid-sized outlets that have fewer locations than what is specified in the current scheme.

Cross-sectional analysis. Prevalence of kJ labelling by large food outlets on OFD from August to September 2022 was examined. Proportion of discretionary (‘junk food’) items on menus from mid-sized outlets was assessed.

Forty-three unique large food outlets on company (e.g. MyMacca’s) and third party OFD (Uber Eats, Menulog, Deliveroo) within Sydney, Australia. Ninety-two mid-sized food outlets were analysed.

N/A.

On company OFD apps, 35 % (7/23) had complete kJ labelling for each menu item. In comparison, only 4·8 % (2/42), 5·3 % (2/38) and 3·6 % (1/28) of large outlets on Uber Eats, Menulog and Deliveroo had complete kJ labelling at all locations, respectively. Over three-quarters, 76·3 % (345/452) of menu items from mid-sized outlets were classified as discretionary.

Kilojoule labelling was absent or incomplete on a high proportion of online menus. Mid-sized outlets have abundant discretionary choices and yet escape criteria for mandatory menu labelling laws. Our findings show the need to further monitor the implementation of nutrition policies on OFD.

Different forms of public and private regulation have been used to improve the healthiness of food retail environments. The aim of this scoping review was to systematically examine the types of private regulatory measures used to create healthy food retail environments, the reporting of the processes of implementation, monitoring, review and enforcement and the barriers to and enablers of these.

Scoping review using the Johanna Briggs Institute guidelines. Ovid MEDLINE, PsycINFO, Embase, CINAHL Plus, Business Source Complete and Scopus databases were searched in October 2020 and again in September 2023 using terms for ‘food retail’, ‘regulation’ and ‘nutrition’. Regulatory measure type was described by domain and mechanism. Deductive thematic analysis was used to identify reported barriers and enablers to effective regulatory governance processes using a public health law framework.

Food retail.

Food retail settings using private regulatory measures to create healthier food retail environments.

In total, 17 694 articles were screened and thirty-five included for review from six countries, with all articles published since 2011. Articles reporting on twenty-six unique private regulatory measures cited a mix of voluntary (n 16), mandatory (n 6) measures, both (n 2) or did not disclose (n 2). Articles frequently reported on implementation (34/35), with less reporting on the other regulatory governance processes of monitoring (15/35), review (6/35) and enforcement (2/35).

We recommend more attention be paid to reporting on the monitoring, review and enforcement processes used in private regulation to promote further progress in improving the healthiness of food retail environments.

The purpose of this study was to create a typology of longitudinal exposure to food environment based on socio-economic context.

Food environment trajectories were modelled using a sequence analysis method, followed by a logistic regression to describe those trajectories.

The study took place in Quebec, Canada, using food environment data from 2009, 2011 and 2018 merged with participants’ demographic and socio-economic characteristics.

At recruitment, 38 627 participants between the ages of 40 and 69 years from six urban areas in Quebec were included in the CARTaGENE cohort study. The cohort was representative of the Quebec urban population within this age range.

Our study revealed five trajectories of food access over time: (1) limited access to food stores throughout the study period, (2) limited access improving, (3) good access diminishing, (4) good access throughout the period and (5) low access throughout the period. Logistic regression analysis showed that participants who were unable to work (OR = 1·42, CI = 1·08–1·86), lived in households with five or more persons (OR = 1·69, CI = 1·17–2·42) and those living in low-income households (OR = 1·32, CI = 1·03–1·71) had higher odds of experiencing a disadvantaged food environment trajectory. Additionally, the level of education and age of participants were associated with the odds of experiencing a disadvantaged food environment trajectory.

The study demonstrates that people facing socio-economic disadvantage are more likely to experience a disadvantaged food environment trajectory over time.

The objective of this commentary is to provide an overview of the rationale and objectives of the Researching the Obesogenic Food Environment (ROFE) project that was conducted in Ghana and South Africa.

Narration has been used to describe the main objectives, phases as well as the methods used for the conduct of this project.

The project described in this commentary was conducted in Khayelitsha and Mount Frere in South Africa and Ahodwo and Ejuratia for Ghana.

Participants of the study described here include households in South Africa and Ghana, stakeholders and policymakers, and various actors within the food chain in both countries.

The ROFE findings provide a good understanding of the extent of the impact of the food environment on consumption, characteristics of value chains of healthy and unhealthy foods, as well as the potential for improved governance and policy that is relevant to the region. The supplement provides the opportunity to share the extensive findings of the ROFE project. Nine papers that describe the process and findings of the three phases of the ROFE project have been presented. Some of the papers focus on phases of the ROFE, while others cut across different phases and explore the linkages between the phases. Briefly descriptions of key findings of some of the papers in the supplement are provided.

Together, the findings of the ROFE study presented in this supplement have increased understanding of how communities in SA and Ghana interact with their food supplies and have led to identification of specific opportunities to improve food supply policies, in ways that create incentives for the production and consumption of healthy, relative to unhealthy foods.

Sugar-sweetened beverages (SSB) are heavily advertised globally, and SSB consumption is linked to increased health risk. To reduce unhealthy food marketing, Chile implemented a regulation for products classified as high in energies, sugar, saturated fat or sodium, starting with a 2016 ban on child-targeted advertising of these products and adding a 06.00–22.00 daytime advertising ban in 2019. This study assesses changes in television advertising prevalence of ready-to-drink beverages, including and beyond SSB, to analyse how the beverage industry shifted its marketing strategies across Chile’s implementation phases.

Beverage advertisements were recorded during two randomly constructed weeks in April-May of 2016 (pre-implementation) through 2019 (daytime ban). Ad products were classified as ‘high-in’ or ‘non-high-in’ according to regulation nutrient thresholds. Ads were analysed for their programme placement and marketing content.

Chile.

From pre-regulation to daytime ban, child-targeted, daytime and total ads decreased by 51·8 percentage points (p.p.), 51·5 p.p. and 61·8 p.p. for high-in products and increased by 62·9 p.p., 54·9 p.p. and 61·8 p.p. for non-high-in products (Ps < 0·001). Additionally, total ready-to-drink beverage ads increased by 5·4 p.p. and brand-only ads (no product shown) by 7 p.p.

After the regulation implementation, ‘high-in’ ads fell significantly, but ‘non-high-in’ ads rose and continued using strategies targeting children and being aired during daytime. Given research showing that advertising one product can increase preferences for a different product from that same brand and product categories, broader food marketing regulation approaches may be needed to protect children from the harmful effects of food marketing.
