The role of dairy in healthy and sustainable food systems: community voices from India.

BACKGROUND: Managing the role of dairy foods in healthy and sustainable food systems is challenging. Milk production is associated with greenhouse gas emissions and milk-based processed foods can be high in fat, sugar and salt; yet, milk production provides income generating opportunities for farmers and dairy foods provide essential nutrients to young children, with a cultural significance in many communities. This is particularly relevant to India, the world's largest producer of milk. The aim of this study was to use Photovoice, a participatory research method, to explore the experiences and perceptions of communities in India on the role of dairy products in local sustainable and healthy food systems. METHODS: Purposive sampling recruited two women's self-help groups in Visakhapatnam, Andhra Pradesh: one in a rural area and one in an urban area. A total of 31 participants (10-17 urban group and 12-14 rural group), produced photographs with captions to represent their views on how dairy was produced, sold, and consumed in their community. A discussion workshop was held in each area, with prompts to consider health and the environment. Workshop transcripts, photographs and captions were analysed qualitatively using thematic analysis. RESULTS: A range of experiences and perceptions were discussed by the two women's self help groups. Participants had an awareness of their local food system and how stages of dairy food supply chains were non-linear and inherently interconnected. Three main themes were identified: 1) Quality and value matters to producers and consumers; 2) The need to adapt to sustain dairy farmer livelihoods in water scarce areas; 3) It's not only about health. CONCLUSIONS: Moderate milk-producing states such as Andhra Pradesh will continue to develop their dairy industry through policy actions. Including communities in policy discussions through innovative methods like Photovoice can help to maximise the positive and minimise the negative role of dairy in evolving local food systems.

The "Cinderella sector": The challenges of promoting food and nutrition for young children in early years' settings in England.

The quality of food that children eat in early childhood has profound impacts on their future wellbeing. In England, many children eat the majority of meals in early years' settings including nurseries and childminders. We conducted 16 interviews with 18 stakeholders exploring food provision, the use of voluntary nutrition guidelines, and the effects of government support on the early years' sector. Key themes emerging from our thematic analysis included feeling insufficiently consulted, undervalued, support being unequally distributed, needing to fill multiple support roles for families, disagreement about the role and effect of voluntary nutrition standards, and being chronically underfunded.

Identifying the views of adolescents in five European countries on the drivers of obesity using group model building.

BACKGROUND: To make effective progress towards a global reduction in obesity prevalence, there needs to be a focus on broader structural factors, beyond individual-level drivers of diet and physical activity. This article describes the use of a systems framework to develop obesity prevention policies with adolescents. The aim of this research was to use the group model building (GMB) method to identify young people's perceptions of the drivers of adolescent obesity in five European countries, as part of the EU-funded Co-Create project. METHODS: We used GMB with four groups of 16-18-year-olds in schools in each of the five European countries (The Netherlands, Norway, Poland, Portugal and the UK) to create causal loop diagrams (CLDs) representing their perceptions of the drivers of adolescent obesity. The maps were then merged into one, using a new protocol. RESULTS: Two hundred and fifty-seven participants, aged 16-18 years, engaged in 20 separate system mapping groups, each of which generated 1 CLD. The findings were largely congruent between the countries. Three feedback loops in the merged diagram particularly stand out: commercial drivers of unhealthy diets; mental health and unhealthy diets; social media use, body image and motivation to exercise. CONCLUSIONS: GMB provides a novel way of eliciting from young people the system-based drivers of obesity that are relevant to them. Mental health issues, social media use and commercial practices were considered by the young people to be key drivers of adolescent obesity, subjects that have thus far had little or no coverage in research and policy.

A Photovoice Study to Reveal Community Perceptions of Highly Processed Packaged Foods in India.

India is experiencing a nutrition transition, with sales of packaged and processed foods rapidly increasing in recent years. This study sought to understand the views and experiences of self-help groups about highly processed, packaged food in Visakhapatnam, India, using the Photovoice method. Participants were able to record, reflect on and critique their environments through participatory analysis, identifying key themes, and offering a critical lens on their food environment and experiences. On an average eight and 14 members participated in the Photovoice workshops held in urban and rural Visakhapatnam respectively. The key themes emerging from the photos and text data are that participants experienced highly processed packaged foods as being: 1) democratic (easily available and consumed by all, affordable and accessible; 2) convenient (easy to prepare) and 3) unhealthy (for human consumption and for environmental sustainability). These data demonstrate the challenges facing public health nutritionists in wishing to shift dietary behaviors to healthy habits: on the surface participants acknowledged their unhealthy characteristics, however these products may now be embedded in dietary culture. Traditional methods for changing dietary habits may not be able to capture the complexity and systems approach is required to explore the most effective entry points for affecting change.

Systems Thinking as a Framework for Analyzing Commercial Determinants of Health.

Policy Points: Worldwide, more than 70% of all deaths are attributable to noncommunicable diseases (NCDs), nearly half of which are premature and apply to individuals of working age. Although such deaths are largely preventable, effective solutions continue to elude the public health community. One reason is the considerable influence of the "commercial determinants of health": NCDs are the product of a system that includes powerful corporate actors, who are often involved in public health policymaking. This article shows how a complex systems perspective may be used to analyze the commercial determinants of NCDs, and it explains how this can help with (1) conceptualizing the problem of NCDs and (2) developing effective policy interventions. CONTEXT: The high burden of noncommunicable diseases (NCDs) is politically salient and eminently preventable. However, effective solutions largely continue to elude the public health community. Two pressing issues heighten this challenge: the first is the public health community's narrow approach to addressing NCDs, and the second is the involvement of corporate actors in policymaking. While NCDs are often conceptualized in terms of individual-level risk factors, we argue that they should be reframed as products of a complex system. This article explores the value of a systems approach to understanding NCDs as an emergent property of a complex system, with a focus on commercial actors. METHODS: Drawing on Donella Meadows's systems thinking framework, this article examines how a systems perspective may be used to analyze the commercial determinants of NCDs and, specifically, how unhealthy commodity industries influence public health policy. FINDINGS: Unhealthy commodity industries actively design and shape the NCD policy system, intervene at different levels of the system to gain agency over policy and politics, and legitimize their presence in public health policy decisions. CONCLUSIONS: It should be possible to apply the principles of systems thinking to other complex public health issues, not just NCDs. Such an approach should be tested and refined for other complex public health challenges.

Comparative institutional analysis for public health: governing voluntary collaborative agreements for public health in England and the Netherlands.

Democratic institutions and state-society relations shape governance arrangements and expectations between public and private stakeholders about public health impact. We illustrate this with a comparison between the English Public Health Responsibility Deal (RD) and the Dutch 'All About Health…' (AaH) programme. As manifestations of a Whole-of-Society approach, in which governments, civil society and business take responsibility for the co-production of economic utility and good health, these programmes are two recent collaborative platforms based on voluntary agreements to improve public health. Using a 'most similar cases' design, we conducted a comparative secondary analysis of data from the evaluations of the two programmes. The underlying rationale of both programmes was that voluntary agreements would be better suited than regulation to encourage business and civil society to take more responsibility for improving health. Differences between the two included: expectations of an enforcing versus facilitative role for government; hierarchical versus horizontal coordination; big business versus civil society participants; top-down versus bottom-up formulation of voluntary pledges and progress monitoring for accountability versus for learning and adaptation. Despite the attempt in both programmes to base voluntary commitments on trust, the English 'shadow of hierarchy' and adversarial state-society relationships conditioned non-governmental parties to see the pledges as controlling, quasi-contractual agreements that were only partially lived up to. The Dutch consensual political tradition enabled a civil society-based understanding and gradual acceptance of the pledges as the internalization by partner organizations of public health values within their operations. We conclude that there are institutional limitations to the implementation of generic trust-building and learning-based models of change 'Whole-of-Society' approaches.

The Public Health Responsibility Deal: making the workplace healthier?

Background: The Public Health Responsibility Deal (RD) in England is a public-private partnership which aims to improve public health by addressing issues such as health at work. This paper analyses the RD health at work pledges in terms of their likely effectiveness and added value. Methods: A review of evidence on the effectiveness of the RD 'health at work' pledges to improve health in the workplace; analysis of publically available data on signatory organizations' plans and progress towards achieving the pledges; and assessment of the likelihood that workplace activities pledged by signatories were brought about by participating in the RD. Results: The 'health at work' pledges mostly consist of information sharing activities, and could be more effective if made part of integrated environmental change at the workplace. The evaluation of organizations' plans and progress suggests that very few actions (7%) were motivated by participation in the RD, with most organizations likely (57%) or probably (36%) already engaged in the activities they listed before joining the RD. Conclusions: The RD's 'health at work' pledges are likely to contribute little to improving workplace health as they stand but could contribute more if they were incorporated into broader, coherent workplace health strategies.

Television food advertising to children in Malta.

To undertake a cross-sectional survey of the extent and nature of food and beverage advertising to children on Maltese national television stations. Seven national free-to-air channels were recorded for seven consecutive days in March 2014 between 07:00 and 22:00 h. Advertisements were coded according to predefined categories, with a focus on advertisements aired during 'peak' children's viewing times, defined as periods during which more than 25% of children were likely to be watching television on any channel. Food and beverage advertisements were classified as core (healthy), non-core (unhealthy) or miscellaneous foods. Malta. Whole population, with a focus on children. Food and drinks were the most heavily advertised product category (26.9% of all advertisements) across all channels. The proportion of non-core food/drink advertisements was significantly greater during peak compared with non-peak children's viewing times (52 vs 44.6%; p ≤ 0.001). A majority of advertisements aimed at children are for non-core foods, and are typically shown during family-oriented programmes in the late evening rather than being restricted to children's programmes. 'Taste', 'enjoyment' and 'peer status' were the primary persuasive appeals used in adolescent and child-focused advertisements. This first content analysis of television advertising in Malta suggests that there is scope for the implementation of statutory regulation regarding advertising of foods high in fat, sugar and salt (HFSS) during times when children are likely to watch television, rather than during children's programmes only. Ongoing, systematic monitoring is essential for evaluation of the effectiveness of regulations designed to reduce children's exposure to HFSS food advertising on television.

An obesogenic island in the Mediterranean: mapping potential drivers of obesity in Malta.

OBJECTIVE: The prevalence of childhood and adult obesity in Malta is among the highest in the world. Although increasingly recognised as a public health problem with substantial future economic implications for the national health and social care systems, understanding the context underlying the burden of obesity is necessary for the development of appropriate counter-strategies. DESIGN: We conducted a contextual analysis to explore factors that may have potentially contributed to the establishment of an obesogenic environment in Malta. A search of the literature published between 1990 and 2013 was conducted in MEDLINE and EMBASE. Twenty-two full-text articles were retrieved. Additional publications were identified following recommendations by Maltese public health experts; a review of relevant websites; and thorough hand searching of back issues of the Malta Medical Journal since 1990. SETTING: Malta. SUBJECTS: Whole population, with a focus on children. RESULTS: Results are organised and presented using the ANalysis Grid for Elements Linked to Obesity (ANGELO) framework. Physical, economic, policy and socio-cultural dimensions of the Maltese obesogenic environment are explored. CONCLUSIONS: Malta's obesity rates may be the result of an obesogenic environment characterised by limited infrastructure for active living combined with an energy-dense food supply. Further research is required to identify and quantify the strength of interactions between these potential environmental drivers of obesity in order to enable appropriate countermeasures to be developed.

Decision-making criteria among European patients: exploring patient preferences for primary care services.

BACKGROUND: Health economics preference-based techniques, such as discrete choice experiments (DCEs), are often used to inform public health policy on patients' priorities when choosing health care. Although there is general evidence about patients' satisfaction with general-practice (GP) care in Europe, to our knowledge no comparisons are available that measure patients' preferences in different European countries, and use patients' priorities to propose policy changes. METHODS: A DCE was designed and used to capture patients' preferences for GP care in Germany, England and Slovenia. In the three countries, 841 eligible patients were identified across nine GP practices. The DCE questions compared multiple health-care practices (including their 'current GP practice'), described by the following attributes: 'information' received from the GP, 'booking time', 'waiting time' in the GP practice, 'listened to', as well as being able to receive the 'best care' available for their condition. Results were compared across countries looking at the attributes' importance and rankings, patients' willingness-to-wait for unit changes to the attributes' levels and changes in policy. RESULTS: A total of 692 respondents (75% response rate) returned questionnaires suitable for analysis. In England and Slovenia, patients were satisfied with their 'current practice', but they valued changes to alternative practices. All attributes influenced decision-making, and 'best care' or 'information' were more valued than others. In Germany, almost all respondents constantly preferred their 'current practice', and other factors did not change their preference. CONCLUSION: European patients have strong preference for their 'status quo', but alternative GP practices could compensate for it and offer more valued care.

Ageing in the European Union.

The ageing of European populations presents health, long-term care, and welfare systems with new challenges. Although reports of ageing as a fundamental threat to the welfare state seem exaggerated, societies have to embrace various policy options to improve the robustness of health, long-term care, and welfare systems in Europe and to help people to stay healthy and active in old age. These policy options include prevention and health promotion, better self-care, increased coordination of care, improved management of hospital admissions and discharges, improved systems of long-term care, and new work and pension arrangements. Ageing of the health workforce is another challenge, and policies will need to be pursued that meet the particular needs of older workers (ie, those aged 50 years or older) while recruiting young practitioners.

The Public Health Responsibility Deal: how should such a complex public health policy be evaluated?

BACKGROUND: The Public Health Responsibility Deal (RD) in England was launched in 2011 as a public-private partnership which aims to 'tap into the potential for businesses and other influential organisations to make a significant contribution to improving public health by helping us to create this environment'. It has come under criticism from public health advocates and others, who have suggested that it will be ineffective or perhaps even harmful. Like many public health policies, there have also been demands to know whether it 'works'. METHODS: We conducted a scoping review and used this, supplemented with interviews with stakeholders, to develop a detailed logic model of the RD (presented here) to help understand its likely outcomes and the pathways by which these may be achieved as a basis for planning an evaluation. CONCLUSIONS: Evaluations of complex interventions require not just assessment of effects (including outcomes), but also a clear conceptualization of the intervention and its processes. The way the RD and the pledges made by participant organizations has been presented makes it difficult at this stage to evaluate whether the RD 'works' in terms of improving health. Instead, any evaluation needs to put together a jigsaw of evidence about processes, mechanisms and potential future health and non-health impacts, in part using the current scientific evidence. This task is ongoing.

Obstacles to the recognition of medical prescriptions issued in one EU country and presented in another.

A study involving the presentation of 192 Belgian or Finnish prescriptions in pharmacies in five other member states was undertaken to assess whether, as envisaged by European Union law, prescriptions issued in one member state are dispensed by pharmacists in another and to identify factors that influence such decisions. Overall, pharmacists were willing to dispense in 108 cases. Detailed results show important differences depending on the country where prescriptions are presented and whether prescriptions were written by International Nonproprietary Name and in English, as opposed to prescriptions written by brand in a national language.

Is Europe putting theory into practice? A qualitative study of the level of self-management support in chronic care management approaches.

BACKGROUND: Self-management support is a key component of effective chronic care management, yet in practice appears to be the least implemented and most challenging. This study explores whether and how self-management support is integrated into chronic care approaches in 13 European countries. In addition, it investigates the level of and barriers to implementation of support strategies in health care practice. METHODS: We conducted a review among the 13 participating countries, based on a common data template informed by the Chronic Care Model. Key informants presented a sample of representative chronic care approaches and related self-management support strategies. The cross-country review was complemented by a Dutch case study of health professionals' views on the implementation of self-management support in practice. RESULTS: Self-management support for chronically ill patients remains relatively underdeveloped in Europe. Similarities between countries exist mostly in involved providers (nurses) and settings (primary care). Differences prevail in mode and format of support, and materials used. Support activities focus primarily on patients' medical and behavioral management, and less on emotional management. According to Dutch providers, self-management support is not (yet) an integral part of daily practice; implementation is hampered by barriers related to, among others, funding, IT and medical culture. CONCLUSIONS: Although collaborative care for chronic conditions is becoming more important in European health systems, adequate self-management support for patients with chronic disease is far from accomplished in most countries. There is a need for better understanding of how we can encourage both patients and health care providers to engage in productive interactions in daily chronic care practice, which can improve health and social outcomes.

Associations between social media, adolescent mental health, and diet: A systematic review.

Social media use is integral to many adolescents' lives. It brings benefits but can also have detrimental effects on both physical and mental health. We conducted a systematic review examining associations between social media use, adolescent mental health (including body image, self-esteem, stress, interpersonal relationships and loneliness, anxiety, and depressive symptoms), and dietary outcomes. Quantitative studies published between 2019 and 2023 investigating both mental health and diet were searched in 11 databases. The risk of bias was appraised using ROBINS-E. Data were narratively synthesized by type of association, PROGRESS-Plus health equity characteristics, and related to social media influencers. Twenty-one studies were included, of which only one focused on influencers. Sex/gender was the only equity characteristic assessed (n = 8), with mixed results. The findings suggest significant positive correlations between social media use and both depressive and disordered eating symptoms, body dissatisfaction, and anxiety. Four studies identified body image, self-esteem, or anxiety as moderators acting between social media exposure and dietary outcomes. Policy interventions mitigating the impact of social media on adolescents-particularly body image and disordered eating-are needed, alongside follow-up studies on causal pathways, the role of influencers, equity impacts, dietary intake, and the best measurement tools to use.

Adolescents' capacity to take action on obesity: A concurrent controlled before-and-after study of the European CO-CREATE project.

This study evaluated the effect on reported readiness for action and attitudes toward obesity prevention among older adolescents (mean age 17) who took part in a youth-led participatory action research European initiative (CO-CREATE Youth Alliances) compared with a comparison group that acted as controls. This was a concurrent before-and-after controlled study across five countries and took place between September 2019 and October 2020. Adolescents (n = 159) recruited from schools and youth organizations came together with researchers and formed 15 Youth Alliances. An online questionnaire measuring their readiness for action and attitudes toward obesity prevention was administered. Alliance members (n = 62) who filled in the questionnaire at both baseline and postinitiative, and adolescents from the comparison group (n = 132) who completed the questionnaire twice were included in the main analysis. Two-level linear mixed models controlling for country-related variance were fitted. Alliance members scored significantly higher than the comparison group on two factors in each of the readiness for action, responsibility, and drivers of behavior concepts. The findings suggest that involving youth in co-creating policies to prevent obesity may increase adolescents' readiness for action and promote a shift in adolescents' conceptualization of obesity from an individual perspective to a societal responsibility and drivers of behavior.

What policies are there and what policies are missing? A Photovoice study of adolescents' perspectives on obesity-prevention policies in their local environment.

The aim of this study was to investigate adolescents' critical awareness of whether obesity prevention policies targeting physical activity (PA) and nutrition were operating in their local community. Participants were 41 adolescents (aged 16-18, 90% women) recruited from three communities in Poland. Prior to this study, they were involved in obesity-prevention participatory initiatives (conducted within the CO-CREATE project), where obesity-related public policy limitations were analyzed in a youth-led discussion. A Photovoice exercise was designed to capture obesity-related public policies that were either present or absent in young people's local environments. The photographs (N = 213) were coded and mapped according to the policy themes they illustrated, using the MOVING and NOURISHING frameworks. The public policies represented in the photographs are most frequently related to: healthy retail or food service environments; food advertising or promotion; structures and surroundings that promote PA; and infrastructure and opportunities that support public or active transport. Adolescents are critically aware of the presence and lack of specific public policies operating in their local environment, particularly policies affecting structural aspects of food and PA environments. Policy-oriented photovoice exercises may prompt critical awareness among adolescents and empower them to contribute to obesity prevention policy processes.

System mapping with adolescents: Using group model building to map the complexity of obesity.

Public health research and practice is increasingly employing systems thinking to help grapple with complex issues, from obesity to HIV treatment. At the same time, there is growing recognition that to address a given problem it is essential collaborate with those most at risk of or affected by it. Group model building (GMB), a process grounded in system dynamics, combines systems thinking and participatory methods to structure and address complex issues. As part of the CO-CREATE project we conducted GMB sessions with young people in six countries to create causal loop diagrams showing the factors that they believe drive obesity. This paper describes the background to GMB and the process we used to construct causal loop diagrams; it discusses how GMB contributed to generating noteworthy and useful findings, and the strengths and limitations of the method. Using GMB, we identified areas of concern to adolescents in relation to obesity that have so far had little attention in obesity research and policy: mental health and online activity. In using GMB, we also helped answer calls for a more participatory approach to youth involvement in research and policy development.

The Commercial Determinants of Health and Evidence Synthesis (CODES): methodological guidance for systematic reviews and other evidence syntheses.

BACKGROUND: The field of the commercial determinants of health (CDOH) refers to the commercial products, pathways and practices that may affect health. The field is growing rapidly, as evidenced by the WHO programme on the economic and commercial determinants of health and a rise in researcher and funder interest. Systematic reviews (SRs) and evidence synthesis more generally will be crucial tools in the evolution of CDOH as a field. Such reviews can draw on existing methodological guidance, though there are areas where existing methods are likely to differ, and there is no overarching guidance on the conduct of CDOH-focussed systematic reviews, or guidance on the specific methodological and conceptual challenges. METHODS/RESULTS: CODES provides guidance on the conduct of systematic reviews focussed on CDOH, from shaping the review question with input from stakeholders, to disseminating the review. Existing guidance was used to identify key stages and to provide a structure for the guidance. The writing group included experience in systematic reviews and other forms of evidence synthesis, and in equity and CDOH research (both primary research and systematic reviews). CONCLUSIONS: This guidance highlights the special methodological and other considerations for CDOH reviews, including equity considerations, and pointers to areas for future methodological and guideline development. It should contribute to the reliability and utility of CDOH reviews and help stimulate the production of reviews in this growing field.

Learning from the CO-CREATE project: A protocol for systems thinking across research (STAR).

The CO-CREATE project aimed to work with young people to create, inform, and disseminate obesity-preventive evidence-based policies using a complex systems perspective. This paper draws lessons from this experience and proposes a protocol for embedding systems thinking within a research project. We first draw on existing systems thinking frameworks to analyze how systems thinking was translated across CO-CREATE, including the flow and relationship between the work packages and in the methods used. We then take the lessons from CO-CREATE and the principles of existing systems thinking frameworks-which focus on various points of intervention planning and delivery but not on research projects as a whole-to formulate a protocol for embedding systems thinking across a research project. Key lessons for future planning and delivery of systems-oriented research projects include incorporating "boundary critique" by capturing key stakeholder (adolescent) values and concerns; working to avoid social exclusion; ensuring methodological pluralism to allow for reflection and responsiveness (with methods ranging from group model building, Photovoice, and small group engagement); getting policy recipients to shape key questions by understanding their views on the critical drivers of obesity early on in the project; and providing opportunity for intraproject reflection along the way.
