Creating supportive eating places: a systematic review of food service initiatives

More than the worksite cafeteria: the workplace food environment of small and medium-sized enterprises in the Netherlands

OBJECTIVE

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).

DESIGN

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

SETTING

Dutch SMEs.

PARTICIPANTS

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

RESULTS

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.

CONCLUSIONS

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.

Barriers and facilitators to implementation of healthy food and drink policies in public sector workplaces: a systematic literature review

CONTEXT

Many countries and institutions have adopted policies to promote healthier food and drink availability in various settings, including public sector workplaces.

OBJECTIVE

The objective of this review was to systematically synthesize evidence on barriers and facilitators to implementation of and compliance with healthy food and drink policies aimed at the general adult population in public sector workplaces.

DATA SOURCES

Nine scientific databases, 9 grey literature sources, and government websites in key English-speaking countries along with reference lists.

DATA EXTRACTION

All identified records (N = 8559) were assessed for eligibility. Studies reporting on barriers and facilitators were included irrespective of study design and methods used but were excluded if they were published before 2000 or in a non-English language.

DATA ANALYSIS

Forty-one studies were eligible for inclusion, mainly from Australia, the United States, and Canada. The most common workplace settings were healthcare facilities, sports and recreation centers, and government agencies. Interviews and surveys were the predominant methods of data collection. Methodological aspects were assessed with the Critical Appraisal Skills Program Qualitative Studies Checklist. Generally, there was poor reporting of data collection and analysis methods. Thematic synthesis identified 4 themes: (1) a ratified policy as the foundation of a successful implementation plan; (2) food providers' acceptance of implementation is rooted in positive stakeholder relationships, recognizing opportunities, and taking ownership; (3) creating customer demand for healthier options may relieve tension between policy objectives and business goals; and (4) food supply may limit the ability of food providers to implement the policy.

CONCLUSIONS

Findings suggest that although vendors encounter challenges, there are also factors that support healthy food and drink policy implementation in public sector workplaces. Understanding barriers and facilitators to successful policy implementation will significantly benefit stakeholders interested or engaging in healthy food and drink policy development and implementation.

Evaluation of an Environmental Nutrition Intervention at the 2018 Commonwealth Games

There has been an increasing expectation that the food provided for athletes at major competition events meets the specific dietary and performance needs of athletes. The aim of this study was to map the range of food service nutrition schemes that were implemented prior to and during a major competition event (2018 Commonwealth Games) and evaluate these schemes through staff training satisfaction, athlete feedback, and quality assurance checks. This study followed a case study design with nutrition schemes as follows: informing (nutrition labelling), enabling (staff training, nutrition service), and engineering (modification to menus and recipes). Overall, participants reported that they easily found items on the menu that met their nutritional/dietary needs. When asked how useful the schemes were in helping them to identify items that meet their needs, the majority of participants found the nutrition cards (n = 227, 71%) and serving staff (n = 212, 66%) 'useful/very useful'. 'Good/very good' ratings were received by >90% of respondents for speed of service, staff politeness, and knowledge of the menu. Participants (n = 316) who rated the nutrition staff as 'useful/very useful' gave a higher median rating for the menu. Past events have focused on the impact of a single component in the food environment; however, taking a whole systems approach resulted in more suitable food provision to meet the dietary needs of athletes.

Evaluation of the introduction of a healthy food and drink policy in 13 community recreation centres on the healthiness and nutrient content of customer purchases and business outcomes: An observational study

INTRODUCTION

This observational study assessed the introduction of a comprehensive healthy food and drink policy across 13 community organisation managed aquatic and recreation centres in Victoria, Australia, and the associated changes on business outcomes, and the healthiness of purchases. The policy, based on state government guidelines, mandated that food and drink availability be based on healthiness classification: 'red' (limit) <10%, and 'green' (best choice) >50%, and the remainder 'amber' (choose carefully).

METHODS

Six years of monthly sales data were split into three periods, prior to (1/01/2013-31/12/2014), during (1/01/2015-31/12/2016) and post (1/1/2017-31/12/2018), policy implementation. Using point-of-sale data, food and drink nutrient content, and state guidelines, items were classified as 'red'/'amber'/'green'. Linear models with Newey West standard errors were fitted to compare the mean value of outcomes between post- to pre-policy implementation periods, for each outcome and centre; and were pooled using random effect meta-analyses.

RESULTS

Comparing post- to pre-policy implementation periods, total food sales did not change (mean percentage difference: -3.2% (95% confidence interval (CI) -21% to 14%), though total drink sales declined -27% (CI -37% to -17%). The mean percentage of 'red' foods sold declined by -15% (CI -22% to -7.7%), 'amber' food sales increased 11% (CI 5.5% to 16%). 'Green' food sales did not change (3.3%, CI -1.4% to 8.0%). The mean percentage of 'red' drinks sold declined -37% (CI -43% to -31%), 'amber' and 'green' drink sales increased by 8.8% (CI 3.6% to 14%) and 28% (CI 23% to 33%), respectively. The energy density and sugar content (percentage of total weight/volume) of both food and drinks decreased.

CONCLUSIONS

This study has shown that the implementation of a policy to improve the health of retail food environments can result in a shift towards healthier purchases. Sales revenue from foods did not decline, though revenue from drinks did, indicating future research needs to explore mitigation of this.

Healthy Eats-Evaluation of a Social Marketing Program Delivered in Primary School Settings in Queensland

One in four school children in Australia are overweight or obese. In response, the Healthy Eats program was developed, piloted, and delivered using a whole-of-school approach underpinned by the socio-ecological model to increase fruit and vegetable consumption among children aged 8-10 years in regional Queensland, Australia. This research presents an outcome evaluation of the Healthy Eats program using pre-post data collected throughout 2021 (cross-sectional for knowledge and longitudinal for behaviour) from 19 schools to assess whether changes occurred in students' nutritional knowledge (n = 1868 (pre = 933, post = 935)) and fruit and vegetable consumption (n = 1042 (pre = 521, post = 521)). Knowledge data was collected via self-reports two weeks prior and immediately after the Nutrition Module. Behavioural data on daily fruit and vegetable consumption was gathered via student passports (i.e., surveys) one week before and for four consecutive weeks after the Nutrition Module. Chi-Square Difference tests and t-Tests were conducted with a significance level set at p < 0.05. Across all 19 schools, knowledge of the daily recommended serves of fruit and vegetables improved significantly following participation in the program, aligning knowledge closer to the Australian dietary guidelines. Behavioural results for fruit consumption were favourable, with clear improvements reported. Increases in vegetable consumption were demonstrated in two of the eight schools. A discussion on the knowledge-action gap is provided, including recommendations for future iterations of the Healthy Eats program.

Preparing Future Foodservice Managers: Operational and Educational Characteristics of Student-Operated Restaurants

OBJECTIVE

To study operational, management, and educational experiences of student-operated restaurants (SOR) through the perspective of SOR managers across the US.

METHODS

Qualitative semistructured interviews were conducted with 19 SOR managers. Qualitative case study procedures were used for analysis.

RESULTS

Three themes emerged: (1) objectives and processes in SORs, (2) support received by SORs, and (3) individual experiences in SORs. Within these themes, participants described various methods and designs used to operate SORs. However, participants ultimately perceived that SORs were successful in helping students gain foodservice management skills and be better prepared to be future foodservice managers.

CONCLUSIONS AND IMPLICATIONS

Foodservice managers can connect nutrition principles to practice for consumers. Strong foodservice education through SORs can play a role in students being more competent and prepared for foodservice management careers. Findings provide ideas for foodservice educators as they initiate or refine the use of SORs.

Effectiveness of nutrition interventions on improving diet quality and nutrition knowledge in military populations: a systematic review

CONTEXT

Optimizing nutrition in military groups through improved diet quality and nutrition knowledge is key in supporting the high physical and cognitive demands.

OBJECTIVE

The objective of this investigation was to systematically review the effectiveness of nutrition interventions among military personnel in improving diet quality and/or nutrition knowledge.

DATA SOURCES

Medline, Embase, CINAHL, and Scopus were searched from the earliest records to May 2020.

DATA EXTRACTION

Data were extracted by 2 reviewers. The primary outcomes were diet quality and/or nutrition knowledge.

DATA ANALYSIS

Twenty studies were included. The main intervention approaches identified were nutrition education of individuals (i.e., education-based studies; EB) (n = 12), and manipulation of the food service environment (i.e., dining facility studies; DFACs) (n = 8). The most common strategies were face-to-face lectures (n = 8) for EB, and healthier menus (n = 7) and education of catering staff (n = 6) for DFAC interventions. Most studies (18/20) demonstrated favorable within-group effects; however, dietary changes were inconsistent. Five of 10 studies using a comparator group demonstrated positive between-group differences.

CONCLUSION

Although potential exists for improving diet quality and nutrition knowledge in military populations, the heterogeneity of the studies to date limits conclusions on the most efficacious strategies.

Effectiveness of strategies to decrease animal sourced protein and/or increase plant sourced protein in foodservice settings: a systematic literature review

BACKGROUND

Effective population-based strategies are required to move towards healthy sustainable diets which replace a proportion of animal- with plant-based protein. Foodservice can support this using a variety of strategies across the food supply chain.

OBJECTIVE

This systematic review aimed to evaluate the effectiveness of strategies to decrease animal protein and/or increase plant protein in foodservice settings on uptake, satisfaction, financial, environmental, and dietary intake outcomes.

METHODS

Seven databases were searched in November 2020 with no restriction on study dates to identify peer-reviewed study designs conducted in commercial and institutional foodservices using any strategy to decrease beef, lamb, pork, poultry, eggs, fish or seafood and/or increase legumes/pulses, legume/pulse-based meat substitutes or nuts and reported this review's primary outcome, uptake by consumers either quantitatively or qualitatively. Secondary outcomes were satisfaction and financial, environmental, and dietary intake outcomes. Titles/abstracts then full texts were screened independently by two authors. The Mixed Methods Appraisal Tool was used for quality appraisal. Results were described using a narrative synthesis by strategy type. The protocol is registered with PROSPERO (CRD42021235015).

RESULTS

From 20,002 records identified, 38 studies met eligibility criteria, of which 16% were high quality. Strategies included forced restriction (n=4), menu re-design (n=6), recipe re-design (n=6), service re-design (n=4), menu labelling (n=7), prompt at point of sale (n=7) and multi-pronged strategies (n=4). Menu labelling, prompting at the point of sale and re-designing menus, recipes, and service increased uptake of target foods in most studies with the largest consistent changes in menu re-design. Few studies explored secondary outcomes. Recipe re-design, prompt at the point of sale and menu labelling strategies that measured satisfaction found a positive or neutral effect.

CONCLUSIONS

The most promising strategies are likely in menu re-design, followed by menu labelling and service re-design. Satisfaction appears to not be negatively impacted by recipe re-design, prompting at the point of sale and menu labelling. More studies are needed to evaluate financial, environmental, and dietary outcomes.

Proximal and distal influences on dietary change among a diverse group with prediabetes participating in a pragmatic, primary care nurse-led intervention: a qualitative study

OBJECTIVE

To understand motivators, facilitators and challenges to dietary change amongst a diverse sample of New Zealanders with prediabetes participating in a primary care nurse-led individualised dietary intervention.

DESIGN

A qualitative study involving semi-structured, face-to-face interviews with a stratified sample of adults with prediabetes and BMI ≥ 25 kg/m2, purposefully selected from a larger 2-year primary care-based prediabetes dietary intervention study. Thematic analysis was undertaken. A socio-ecological model guided interpretation.

SETTING

Hawke's Bay, Aotearoa/New Zealand, April 2018-March 2020.

PARTICIPANTS

Fifty-eight people aged 28-69 years, with similar numbers of men and women, indigenous Māori and non-Māori, and those who had and had not regressed to normoglycaemia at 6 months.

RESULTS

Motivators for wanting to make dietary changes were determination not to progress to diabetes; wanting to be healthy and contribute to others and encouragement by others. Facilitators for adopting and maintaining changes were a strong desire to be healthy; personal determination and feeling supported. Challenges were compromised control over life and environmental factors; feeling unsupported by others; social occasions; financial constraints and living with other health conditions. Developing their own strategies to overcome challenges was empowering, enabling a sense of control. These factors were similar across demographic and glycaemic outcome groups.

CONCLUSIONS

Influences on dietary change involved personal, interpersonal, organisational, environmental and policy factors. Although findings appeared similar across groups, dietary interventions need to address the specific ways motivators, facilitators and challenges manifest for individuals and social groups and be tailored accordingly within the context of the wider obesogenic and socio-economic environment.

"Just So You Know, It Has Been Hard": Food Retailers' Perspectives of Implementing a Food and Nutrition Policy in Public Healthcare Settings

Mandated policies to improve food environments in public settings are an important strategy for governments. Most Australian governments have mandated policies or voluntary standards for healthy food procurement in healthcare facilities, however, implementation and compliance are poor. A better understanding of the support required to successfully implement such policies is needed. This research explored food retailers' experiences in implementing a mandated food and nutrition policy (the Policy) in healthcare settings to identify barriers, enablers, and impacts of compliance. Three 90-min workshops facilitated by two public health practitioners were undertaken with 12 food retailers responsible for operating 44 outlets across four hospitals in Perth, Western Australia. Workshop discussions were transcribed non-verbatim and inductive thematic content was analyzed. Three main themes were identified: (1) food retailers had come to accept their role in implementing the Policy; (2) the Policy made it difficult for food retailers to operate successfully, and; (3) food retailers needed help and support to implement the Policy. Findings indicate the cost of implementation is borne by food retailers. Communications campaigns, centralized databases of classified products, reporting frameworks, recognition of achievements, and dedicated technical expertise would support achieving policy compliance. Feasibility assessments prior to policy implementation are recommended for policy success.
