A whole system approach to childhood obesity: how a supportive environment was created in the city of Brighton and Hove, United Kingdom.

Childhood obesity is a growing global challenge, and no country has yet reversed the upward trend in prevalence. The causes are multifaceted, spanning individual, societal, environmental, and political spheres. This makes finding solutions complex as traditional linear models of treatment and effect have proven only minimally successful or unfeasible at the population level. There is also a paucity of evidence of what works, and few examples of intervention that operate on a 'whole systems' level. The city of Brighton in the United Kingdom has experienced a downward trend in child obesity rates compared to national figures. The aim of this study was to explore what has led to successful change in the city. This was done through a review of local data, policy and programs, and thirteen key informant interviews with key stakeholders involved in the local food and healthy weight agenda. Our findings highlight key mechanisms that have plausibly contributed to a supportive environment for obesity reduction in Brighton according to key local policy and civil society actors. These mechanisms include; a commitment to early years intervention such as breastfeeding promotion; a supportive local political context; the ability to tailor interventions to community needs; governance structures and capacity that enable cross-sectoral collaboration; and a citywide framing of obesity solutions in the context of a 'whole system' approach. However, substantial inequalities persist in the city. Engaging families in areas of high deprivation and operating in an increasingly difficult context of national austerity are persistent challenges. This case study sheds light on some mechanisms of what a whole systems approach to obesity looks like in practice in a local context. This is of relevance to both policymakers and healthy weight practitioners across a spectrum of sectors who need to be engaged to tackle child obesity.

Applying the 'Candidacy' Model to understand access to key nutrition, food & health services in LMIC contexts: a qualitative study in Odisha, India.

In order to make progress towards Sustainable Development Goal 2 - Zero Hunger - we must acquire a better understanding of what continues to hamper achieving food security, particularly in contexts where progress has been achieved, but has then faltered. This article investigates access to nutrition and food services in three of the Indian state of Odisha's traditionally poorer districts, where a large number of the state's most marginalised populations live. Semi-structured interviews were carried out in 11 villages. The Dixon-Woods Candidacy Model was employed to provide greater insight into the experiences of access to health and nutrition services, from both the supply and the demand sides. We found that there are many points along the journey that hamper access. We identified two levels of gatekeepers that can create (or remove) barriers, the first as front-line service providers and the second as high-level officials. The candidacy model shows that marginalisation caused by identity, poverty and education disparities hampers progress throughout this journey. This article aims to provide a view to improve our understanding of access to health, food and nutrition services, to improve food security, and to show the value of the candidacy model applied to an LMIC health setting.

Stories of change in nutrition in Burkina Faso 1992-2018: a macro-level perspective.

Looking back at the development of successful enabling environments for nutrition may inform policymakers on how to accelerate progress to end all forms of malnutrition by 2030. As under-five stunting declined substantially in Burkina Faso, from a peak at 45% in 1998/99 to 25% in 2018, we analyzed through a stories of change approach the actors, ideas, initiatives, policies and capacities which enabled wide-scale nutrition progress. We triangulated findings from policy analysis, stakeholder mapping, and national-level semi-structured interviews (n = 20). We found that since 2002, nutrition has been anchored in the Ministry of Health, where leadership advocated for the creation of coordination bodies, enabling a coherent defining of nutrition and laying groundwork for better integration of nutrition into and prioritization of nutrition by the health and tangential ministries. Under the leadership of the Ministry of Health and its partners, horizontal and vertical coherence in nutrition action increased, through effective cooperation between nutrition actors; increasing intersectoral collaboration, particularly with the influential agriculture sector; and increasing funding to support nutrition-sensitive programming and build the capacity of nutrition staff. Nevertheless, sustainably organizing funding and human resources at the decentralized level remained challenging, in a context of emerging threats such as climate change and insecurity. Burkina Faso's health sector's success in creating an enabling environment for nutrition may have contributed to improvements in child nutrition alongside other sectoral improvements. Enhancing accountability of the Health, Agriculture, WASH, Education and Social Protection sectors and empowering decentralized bodies to take nutrition-relevant decisions may help accelerating progress in nutrition.

Stories of change in nutrition: lessons from a new generation of studies from Africa, Asia and Europe.

How does nutrition improve? We need to understand better what drives both positive and negative change in different contexts, and what more can be done to reduce malnutrition. Since 2015, the Stories of Change in Nutrition studies have analysed and documented experiences in many different African and Asian countries, to foster empirically-grounded experiential learning across contexts. This article provides an overview of findings from 14 studies undertaken in nine countries in South Asia, sub-Saharan Africa, and Europe between 2017 and 2021. The studies used a combination of methods, including regression-decomposition analyses of national datasets to assess determinants of nutritional change; policy process and food environment analyses; and community-level research assessing attitudes to change. This article takes a narrative synthesis approach to identify key themes across the studies, paying particular attention to multisectoral determinants, changes in the food environment, the role of structural factors (including longstanding social inequities), and changes in political commitment, cross-sectoral coherence and capacity. Given the inherent multisectoral nature of nutrition, many countries are experimenting with different models of ensuring coherence across sectors that are captured in this body of work. The relative immaturity of the policy sector in dealing with issues such as obesity and overweight, and associated influences in the wider food environment, adds a further challenge. To address these interrelated issues, policy must simultaneously tackle nutrition's upstream (social/economic/equity) and downstream (health and dietary) determinants. Studies synthesised here provide empirically-driven inspiration for action.

Changes in Nigeria's enabling environment for nutrition from 2008 to 2019 and challenges for reducing malnutrition.

Key 2025 global nutrition targets are unlikely to be met at current rates of progress. Although actions necessary to reduce undernutrition are already mostly known, knowledge gaps remain about how to implement these actions in contextually appropriate ways, and at scales commensurate with the magnitude of the problem. This study describes the nutrition enabling environment in Nigeria, a country that contributes significantly to the global undernutrition burden, and identifies potential entry points for improving the enabling environment that could facilitate implementation and scale-up of essential intervention coverage. Study data were obtained from two sources: content analysis of 48 policies/strategies from agriculture, economic, education, environment, health, nutrition, and water/sanitation/hygiene sectors; and interviews at federal level (16) and in two states (Jigawa (10) and Kaduna (9) States). The study finds that aspects of the enabling environment improved between 2008 and 2019 and facilitated improvements in implementation of nutrition-specific and nutrition-sensitive interventions. Enabling environment components that improved included the framing of nutrition as a multisectoral issue, nutrition advocacy, political attention, evidence around intervention coverage, civil society involvement, and activity of nutrition champions. These factors have been especially important in creating and sustaining momentum for addressing malnutrition. While challenges remain in these aspects, greater challenges persist for factors needed to convert momentum into improvements in nutrition outcomes. Research and data that facilitate shared understanding of nutrition; improved multisectoral and vertical coordination; increased and improved delivery and operational capacity; and increased resource mobilization will be especially important for achieving future progress in nutrition in Nigeria.

Understanding drivers of stunting reduction in Nigeria from 2003 to 2018: a regression analysis.

Nigeria is a high burden country for stunting. Stunting reduction has been slow and characterized by unequal progress across the 36 states and federal capital territory of the country. This study aimed to assess the changes in prevalence of stunting and growth determinants from 2003 to 2018, identify factors that predicted the change in stunting, and project future stunting prevalence if these predicted determinants improve. Trend and linear decomposition analyses of growth outcomes and determinants were conducted using 2003, 2008, 2013, and 2018 Nigeria Demographic and Health Survey data. Pooled data included 57,507 children 0 to 59 months old. Findings show that stunting and severe stunting significantly reduced from 43 to 37% and 23% to 17%, respectively (p < 0.001), between 2003 and 2018. Disturbingly, height-for-age z-scores at birth significantly decreased, indicating risks of potential future stunting increase. Improvements in nine stunting determinants (maternal body mass index, maternal height, ≥ 4 antenatal care visits, health facility delivery, reduced child illnesses, asset index, maternal education, paternal education, and preceding birth interval) predicted stunting reductions in children 0-59 months. Few of these nine determinants improved in subpopulations with limited stunting progress. Intra-sectoral and multisectoral coordination were potentially inadequate; 12% of children had received all of three selected health sector interventions along a continuum of care and 6% had received all of six selected multisector interventions. Forward looking projections suggest that increased efforts to improve the nine predictors of stunting change can reduce under-five stunting in Nigeria to ≤ 27% in the short term.

Stories of change in nutrition in Burkina Faso 1992-2018: a micro-level perspective.

Looking back at what has effectively improved nutrition may inform policy makers on how to accelerate progress to end all forms of malnutrition by 2030. As under-five stunting declined substantially in Burkina Faso, we analyzed its nutrition story at the micro-level. We conducted a regression-decomposition analysis to identify demographic and health drivers associated with change in height-for-age using longitudinal, secondary, nationally-representative data. We triangulated results with findings from semi-structured community interviews (n = 91) in two "model communities" with a history of large stunting reduction. We found that improvement in immunization coverage, assets accumulation and reduction in open defecation were associated with 23%, 10% and 6.1% of the improvement in height-for-age, respectively. Associations were also found with other education, family planning, health and WASH indicators. Model communities acknowledged progress in the coverage and quality of nutrition-specific and nutrition-sensitive sectoral programs co-located at the community level, especially those delivered through the health and food security sectors, though delivery challenges remained in a context of systemic poverty and persistent food insecurity. Burkina Faso's health sector's success in improving coverage of nutrition and healthcare programs may have contributed to improvements in child nutrition alongside other programmatic improvements in the food security, WASH and education sectors. Burkina Faso should continue to operationalize sectoral nutrition-sensitive policies into higher-quality programs at scale, building on its success stories such as vaccination. Community leverage gaps and data gaps need to be filled urgently to pressure for and monitor high coverage, quality delivery, and nutrition impact of agriculture, education, and WASH interventions.

Holding no-one back: The Nutrition Equity Framework in theory and practice.

Equity remains poorly conceptualised in current nutrition frameworks and policy approaches. We draw on existing literatures to present a novel Nutrition Equity Framework (NEF) that can be used to identify priorities for nutrition research and action. The framework illustrates how social and political processes structure the food, health and care environments most important to nutrition. Central to the framework are processes of unfairness, injustice and exclusion as the engine of nutrition inequity across place, time and generations, ultimately influencing both nutritional status and people's space to act. The NEF illustrates conceptually how action on the socio-political determinants of nutrition is the most fundamental and sustainable way of improving nutrition equity for everyone everywhere, through 'equity-sensitive nutrition'. Efforts must ensure, in the words of the Sustainable Development Goals, that not only is "no one left behind" but also that the inequities and injustices we describe do not hold anyone back from realising their right to healthy diets and good nutrition.

Conflict of Interest in Nutrition: Where's the Power? Comment on "Towards Preventing and Managing Conflict of Interest in Nutrition Policy? An Analysis of Submissions to a Consultation on a Draft WHO Tool".

Actual or perceived conflict of interests (COIs) among public and private actors in the field of nutrition must be managed. Ralston et al expose sharply contrasting views on the new World Health Organization (WHO) COI management tool, highlighting the contested nature of global debates. Both the WHO COI tool and the Ralston et al paper are largely quiet on aspects of power among different actors, however, which we argue is integral to these conflicts. We suggest that power needs to be acknowledged as a factor in COI; that it needs to be systematically assessed in COI tools using approaches we outline here; and that it needs to be explicitly addressed through COI mechanisms. We would recommend that all actors in the nutrition space (not only private companies) are held to the same COI standards, and we would welcome further studies such as Ralston et al to further build accountability.

Sustainable food systems and nutrition in the 21st century: a report from the 22nd annual Harvard Nutrition Obesity Symposium.

Food systems are at the center of a brewing storm consisting of a rapidly changing climate, rising hunger and malnutrition, and significant social inequities. At the same time, there are vast opportunities to ensure that food systems produce healthy and safe food in equitable ways that promote environmental sustainability, especially if the world can come together at the UN Food Systems Summit in late 2021 and make strong and binding commitments toward food system transformation. The NIH-funded Nutrition Obesity Research Center at Harvard and the Harvard Medical School Division of Nutrition held their 22nd annual Harvard Nutrition Obesity Symposium entitled "Global Food Systems and Sustainable Nutrition in the 21st Century" in June 2021. This article presents a synthesis of this symposium and highlights the importance of food systems to addressing the burden of malnutrition and noncommunicable diseases, climate change, and the related economic and social inequities. Transformation of food systems is possible, and the nutrition and health communities have a significant role to play in this transformative process.

Historicising global nutrition: critical reflections on contested pasts and reimagined futures.

The COVID-19 pandemic has provoked a range of economic shocks, food systems shocks, public health crises and political upheavals across the globe, prompting a rethink of associated global systems. Prepandemic anticolonial movements that challenged hierarchies of race, space, gender and expert knowledge in global health took on new meaning in the context of the unequal impacts of the SARS-CoV-2 virus as it moved through different kinds of spaces and distinct political contexts. In light of these dynamics, and the desire of many current practitioners in global health to reimagine the future, the need for critical analyses of the recent past have become more urgent. Here we challenge linear understandings of progress in global health-with a focus on the field of nutrition-by returning to consider a previous cycle of dramatic social, political and economic change that prompted serious challenges to the dominance of Western powers and US-based philanthro-capitalists. With a 'global' health and nutrition audience in mind, we put forward considerations on why a better understanding of the continuities and divergences between this past and the present moment are necessary to challenge a status quo that was, and is, highly flawed.

Stories of change in nutrition from Africa and Asia: an introduction to a special series in Food Security.

Malnutrition in all its forms continues to be a massive global challenge, and the past decade has seen a growing political attention to addressing malnutrition in different contexts. What has been largely missing so far, and is in growing demand from countries, is tangible, practical and rigorous insights and lessons (from other countries or contexts) on how to translate this burgeoning political momentum into effective policies and programme implementation strategies - and ultimately impact on the ground. This new climate of learning from experience and evidence led to the launch in 2015 of the Stories of Change initiative. This series presents a second wave of studies from six countries (Tanzania, Rwanda, Vietnam, Ghana, Burkina Faso, Nigeria,) and three Indian states (Chhattisgarh, Gujarat, Tamil Nadu). These provide clear evidence combined with compelling narratives on what drives success in addressing all forms of malnutrition - evidence that is necessary for turning global momentum into actual results on the ground. This introductory Opinion is published with the first set of papers. It will be followed by a thorough synthesis of papers as a conclusion of the Series. We hope that the lessons embedded in these Stories of Change will inform and inspire the deliberations and outcomes of the UN Food Systems Summit and the second Nutrition for Growth Summit to be held this year, and the actions of those in the global food and nutrition system working for positive change.

The Basic Determinants of Malnutrition: Resources, Structures, Ideas and Power.

BACKGROUND: While child undernutrition is improving overall, different population groups are experiencing different outcomes. What sets some groups apart is their experience of the 'basic determinants' of malnutrition, that underpin the 'immediate' and 'underlying' determinants, and that have been much less studied, defined and understood. METHODS: We undertook a qualitative narrative review based in two sets of ideas: nutrition's basic determinants as laid out in the original United Nations Children's Fund (UNICEF) framework, and critical concepts emerging from development studies. These ideas informed searches in Google Scholar, and resulting papers formed the basis for the review. RESULTS: Based on this literature, we expand and clarify the terminology of 'basic determinants' into a new framework, to include (1) resources and (material, human, social and natural) capitals at the basic level; (2) structures including social, market, legal and political systems driven by long-term demographic, economic, and environmental trends; and (3) ideas, beliefs and ideologies prevailing within a given society - crystallising into social norms and institutions - fundamentally shaping how societies are structured around power and marginalisation. We then illustrate with existing literature how these basic factors play out in the food, health and care determinants of malnutrition; and how theories of human rights and collective commons point us towards practical redressal options through improved participation and accountability. CONCLUSION: We show here that the basic determinants are not a black box of 'context,' but can be broken down into comprehensible issues that are amenable to change, and should be considered explicitly in research and action to reduce the global burden of malnutrition.

Factors influencing the performance of community health workers: A qualitative study of Anganwadi Workers from Bihar, India.

Globally, there remain significant knowledge and evidence gaps around how to support Community Health Worker (CHW) programmes to achieve high coverage and quality of interventions. India's Integrated Child Development Services scheme employs the largest CHW cadre in the world-Anganwadi Workers (AWWs). However, factors influencing the performance of these workers remain under researched. Lessons from it have potential to impact on other large scale global CHW programmes. A qualitative study of AWWs in the Indian state of Bihar was conducted to identify key drivers of performance in 2015. In-depth interviews were conducted with 30 AWWs; data was analysed using both inductive and deductive thematic analysis. The study adapted and contextualised existing frameworks on CHW performance, finding that factors affecting performance occur at the individual, community, programme and organisational levels, including factors not previously identified in the literature. Individual factors include initial financial motives and family support; programme factors include beneficiaries' and AWWs' service preferences and work environment; community factors include caste dynamics and community and seasonal migration; and organisational factors include corruption. The initial motives of the worker (the need to retain a job for family financial needs) and community expectations (for product-oriented services) ensure continued efforts even when her motivation is low. The main constraints to performance remain factors outside of her control, including limited availability of programme resources and challenging relationships shaped by caste dynamics, seasonal migration, and corruption. Programme efforts to improve performance (such as incentives, working conditions and supportive management) need to consider these complex, inter-related multiple determinants of performance. Our findings, including new factors, contribute to the global literature on factors affecting the performance of CHWs and have wide application.

Integrating nutrition and physical activity promotion: A scoping review.

BACKGROUND: This paper investigates actions that combine nutrition and physical activity which hold potential for 'double duty action' to tackle multiple forms of malnutrition simultaneously. Expanding on previous research on single component actions, we assessed the state of the literature to map integrated interventions across the life course to analyse potential double duty effects, and identify knowledge gaps and needs for future design, implementation, evaluation and research for effective double duty action. METHODS: A scoping review of peer-reviewed and grey literature was conducted to explore the pathways that extend from combined physical activity and nutrition promotion interventions, with potential synergistic effects on outcomes other than obesity. Electronic databases were searched for studies published between 1 January 2010 and 31 January 2020. Out of 359 articles retrieved, 31 peer-reviewed and 5 grey literature sources met inclusion criteria. Findings from 36 papers reporting on 34 interventions/initiatives were organised into 6 categories, based on implementation across multiple stages of the life course. Double-duty potential was assessed through a further stage of analysis. FINDINGS: This review has identified actions that hold potential for tackling not only obesity, but healthy diets, sedentary behaviour and quality of life more generally, as well as actions that explicitly tackle multiple forms of malnutrition. Importantly, it has identified crucial gaps in current methods and praxis that call for further practice-oriented research, in order to better understand and exploit the synergistic effects of integrated interventions on outcomes other than obesity. CONCLUSIONS: Findings from across implementation settings suggest that even in situations where interventions are aimed at, or framed in terms of, obesity prevention and control, there are unexploited pathways for broader outcomes of relevance to nutrition and health and wellbeing more generally. Future design and evaluation of multisectoral approaches will benefit from an explicit framing of interventions as double-duty oriented.

Understanding the nourishment of bodies at the centre of food and health systems - systemic, bodily and new materialist perspectives on nutritional inequity.

That nutritional inequalities continue to proliferate at a global level requires new insight from all disciplines, given their formation at the intersection of broader inequities in food, health and other systems. This paper argues that critical social scientific perspectives are needed to supplement public health and food focused approaches, which, while helpful, tend to reduce research and intervention to remedial action on malnourished bodies or on food production. A number of alternative perspectives draw on work on both bodies and on systems which are reviewed here. Because both the causes and the impacts of poor nutrition are simultaneously embodied and systemic, our understanding is weakened without considering both sets of literature simultaneously. New-materialist, assemblage or posthuman approaches represent an evolution of these literatures which can reflect on dissolving socio-natural boundaries within contemporary (nutritional) science, whilst retaining a critical edge. Together, the various approaches within this paper help consider the conditions of everyday existence for those living with malnutrition and the range of bodily and systemic factors which assemble their condition.

The challenges of institutionalizing community-level social accountability mechanisms for health and nutrition: a qualitative study in Odisha, India.

BACKGROUND: India has been at the forefront of innovations around social accountability mechanisms in improving the delivery of public services, including health and nutrition. Yet little is known about how such initiatives are faring now that they are incorporated formally into government programmes and implemented at scale. This brings greater impetus to understand their effectiveness. This formative qualitative study focuses on how such mechanisms have sought to strengthen community-level nutrition and health services (the Integrated Child Development Services and the National Rural Health Mission) in the state of Odisha. It fills a gap in the literature on considering how such initiatives are running when institutionalised at scale. The primary research questions were 'what kinds of community level mechanisms are functioning in randomly selected villages in 3 districts of state of Odisha' and 'how are they perceived to function by their members and frontline workers'. METHODS: The study is based on focus group discussions with pregnant women and mothers of children below the age of 2 (n = 12) and with women's self-help groups (n = 12); interviews with frontline health workers (n = 24) and with members of community committees (n = 36). Interviews were analysed thematically using a priori coding derived from wider literature on key accountability themes. RESULTS: Four main types of community-based mechanisms were examined - Mothers committees, Jaanch committees, Village Health and Sanitation Committees and Self-Help Groups. The degree of their effectiveness varied depending on their ability to offer meaningful avenues for participation of their members and empower women for autonomous action. Notably, in most of these mechanisms community participation is very weak, with committees largely controlled by the frontline workers who are supposed to be held to account. However, self-help groups showed real levels of autonomy and collective power. Despite not having an explicit accountability role, these groups were nevertheless effective in advocating for better service delivery and the broader needs of their members to a level not seen in institutional committees. CONCLUSIONS: The study points to the need for community-level mechanisms in India to adequately address issues of participation and empowerment of community members to be successful in contributing to service improvements in health and nutrition.
