RESUMO
PURPOSE: To describe adherence to sustainable healthy diets among a sample of 958 Chilean pre-schoolers (3-6 years) and explore associations between adherence and child and maternal sociodemographic and anthropometric characteristics. METHODS: Children's adherence to sustainable healthy diets was calculated from single multiple-pass 24-h dietary recalls using the Planetary Health Diet Index for children and adolescents (PHDI-C). Higher PHDI-C scores (max score = 150 points) represent greater adherence. Adjusted linear regression models were fitted to explore associations between PHDI-C scores and child and maternal characteristics. RESULTS: Children obtained low total PHDI-C scores (median 50.0 [IQR 39.5-59.8] points). This resulted from low consumption of nuts & peanuts, legumes, vegetables, whole cereals, and vegetable oils; a lack of balance between dark green and red & orange vegetables, inadequate consumption of tubers & potatoes and eggs & white meats, and excess consumption of dairy products, palm oil, red meats, and added sugars. Mean PHDI-C total score was significantly higher (50.6 [95%CI 49.6, 51.7] vs 47.3 [95%CI 45.0, 49.5]) among children whose mothers were ≥ 25 years compared to those with younger mothers. Positive associations were observed between scores for fruits and maternal education, vegetables and maternal age, added sugars and child weight status, while negative associations were observed between fruits and child age, and vegetable oils and maternal education. Scores for dairy products PHDI-C component were lower among girls. CONCLUSION: Adherence to sustainable healthy diets was low among this sample of Chilean children and was significantly associated with maternal age, being lower among children whose mothers were younger.
RESUMO
Background: The COVID-19 pandemic has amplified the need to understand the health and wellbeing of healthcare workers in hospital settings. Crises like the COVID-19 pandemic create poor health outcomes for healthcare workers, yet little is understood about underlying patterns of modifiable health determinants. Objective: The aim of the study was to examine the health and wellbeing data of healthcare workers before and during the COVID-19 pandemic and inform future healthy intervention activities within the workplace. Design: Repeat cross-sectional study pre-2018 and mid-COVID-19 2020. Settings: Rural health service in Victoria, Australia. Participants: All 800 healthcare workers within the health service were invited; of these, 184 (23%) participated at Time 1 and 87 (11%) at Time 2. Methods: Diet, physical activity, sleep behaviours, and psychological distress were collected via online survey in Qualtrics. Pre-COVID-19 pandemic, anthropometry (height, weight, waist circumference, blood pressure), and type 2 diabetes risk were collected by a trained practitioner. However, to reduce burden on healthcare workers mid-COVID-19 pandemic, only self-reported anthropometry was collected. Results: The majority of participants were Australian-born females (84% at both timepoints) with half over the age of 45 (63% Time 1, 53% Time 2). Around half worked part-time (49% Time 1, 54% Time 2), over a third full-time (39% Time 1, 36% Time 2), and the majority reported working regular day shifts in the past 3 months (70% Time 1, 65% Time 2). Among this sample, there were few smokers (9% Time 1, 7% Time 2), and two thirds of participants were living with overweight or obesity (64% Time 1, 67% Time 2). Across both time points, compliance with health guidelines was low; 41% (Time 1) and 42% (Time 2) met fruit, 17% (Time 1) and 12% (Time 2) met vegetable, and just under 50% met physical activity guidelines at both time points. Those reporting moderate to very high levels of psychological stress increased from 42% (Time 1) to 59% (Time 2) (p< 0.05). At Time 1, >80% were at intermediate (39%) or high (33%) risk of developing type 2 diabetes within the next 5 years; and a third (32%) were hypertensive. Reasons for physical inactivity at work included already exercising out-of-work hours (28%), living too far from work (18%), available time (9%), and inflexible work hours (8%). Conclusions: Several high-risk health areas along with opportunities for supporting improved wellbeing were identified in this group of healthcare workers. Psychological distress of healthcare workers urgently needs to be addressed, and this is reinforced by the need to understand the longitudinal impact of COVID-19 on the health and wellbeing of healthcare workers. Workplace settings, such as a health service, is an ideal setting to invest in healthcare workers with individual, organisational, and broader community benefits.
RESUMO
BACKGROUND: Over a quarter of children aged 2-17 years living in Australia are overweight or obese, with a higher prevalence reported in regional and remote communities. Systems thinking approaches that seek to support communities to generate and implement locally appropriate solutions targeting intertwined environmental, political, sociocultural, and individual determinants of obesity have the potential to ameliorate this. There have however been reported challenges with implementation of such initiatives, which may be strengthened by incorporating implementation science methods. METHODS: This pilot randomised controlled trial protocol outlines the development and proposed evaluation of a multicomponent implementation strategy (Action-RESPOND). to increase the implementation of community-based systems thinking child obesity prevention initiatives The target of this intervention is ten rural and regional communities (or local government areas as the unit of allocation) within Northeast Victoria who were participants in a whole-of-systems intervention (RESPOND). Action-RESPOND builds on this intervention by assessing the impact of offering additional implementation strategies to five communities relative to usual care. The development of the multicomponent implementation strategy was informed by the Promoting Action on Research Implementation in Health Services (PARIHS) framework and consists of seven implementation strategies primarily delivered via 'facilitation' methods. Implementation strategies aimed to ensure initiatives implemented are i) evidence-based, ii) address community's specific needs and iii) are suitable for local context. Strategies also aimed to increase the community's capacity to implement, through iv) improving the health promotion team's implementation knowledge and skills, fostering v) leadership, vi) physical resources and vii) community culture to drive implementation. The feasibility, acceptability, potential impact, and cost of the strategy will be assessed at baseline and follow up using surveys administered to key representatives within the community and internal records maintained by the research team. DISCUSSION: By leveraging an existing community-based whole-of-systems intervention, Action-RESPOND offers a unique opportunity to collect pilot feasibility and early empirical data on how to apply implementation and systems science approaches to support obesity prevention in rural and regional communities in Victoria.

OBJECTIVE: To determine (i) the prevalence of overweight and obesity among children presenting to all EDs in a large regional Australian city and (ii) whether age, sex, socioeconomic status (SES) or hospital setting (public vs private) were associated with overweight and obesity. METHODS: This prospective observational study included children aged ≥2 and <18 years who presented to any of three EDs over an 18 month period who had their height and weight measured. Age, sex and residential postcode were collected. Weight category was determined by sex and age standardised body mass index (BMI) z-score. Weight category was assessed by sex, age, SES and hospital setting with chi-squared tests, and ordinal logistic regression with cluster sandwich error estimators. Results were reported using odds ratios (OR) with 95% confidence intervals (CI). RESULTS: Data were collected for 3827 children, of which 11.6% were obese and 19.8% overweight. The prevalence of obesity was highest in those aged 8-14 years and in those from lower SES postcodes. The likelihood of obesity was higher in the public than the private hospitals (OR 0.66, 95% CI 0.51-0.86), whereas the likelihood of overweight was similar (OR 1.00, 95% CI 0.83-1.22). CONCLUSIONS: Almost one-third of children who presented to EDs were overweight or obese. Obesity was particularly high in those aged 8-14 years and those from lower SES postcodes. In the evolving obesity crisis, the high proportion of children presenting to EDs above a healthy weight might represent an opportunity for EDs to identify and refer children for body weight and lifestyle management.
RESUMO
Study Objectives: Insufficient sleep is common among children and adolescents, and can contribute to poor health. School-based interventions potentially could improve sleep behavior due to their broad reach, but their effectiveness is unclear. This systematic review focused on the effects of school-based interventions on sleep behavior among children and adolescents aged 5 to 18 years. Methods: Five electronic databases were searched for randomized controlled trials of sleep health interventions initiated or conducted in school settings and in which behavioral sleep outcomes were measured. Cochrane risk of bias tools were used to assess study quality. Results: From the 5303 database records and two papers from other sources, 21 studies (22 papers) met the inclusion criteria for this review. These studies involved 10 867 children and adolescents at baseline from 13 countries. Most studies (nâ =â 15) were conducted in secondary schools. Sleep education was the most common intervention, either alone (nâ =â 13 studies) or combined with other initiatives (stress management training, nâ =â 2; bright light therapy, nâ =â 1; health education, nâ =â 1). Interventions were typically brief in terms of both the intervention period (medianâ =â 4 weeks) and exposure (medianâ =â 200 minutes). Behavioral outcomes included actigraphy-measured and self-reported sleep patterns, and sleep hygiene. All outcomes had high risk of bias or some concerns with bias. Sleep education interventions were typically ineffective. Later school start times promoted longer sleep duration over 1 week (1 study, high risk of bias). Conclusions: Current evidence does not provide school-based solutions for improving sleep health, perhaps highlighting a need for complex, multi-component interventions (e.g. whole-of-school approaches) to be trialed.
RESUMO
Multicomponent and multisectoral community-based interventions (CBIs) have proven potential in preventing overweight and obesity in children. Synthesizing evidence on the outcomes collected and reported in such CBIs is critical for the evidence of effectiveness and cost-effectiveness. This systematic review aimed to identify the range of outcomes and outcome measurement instruments collected and reported in multisectoral and multicomponent CBIs for obesity prevention in children. A systematic search updated an existing review and extended the search to 11 academic databases (2017-2023) and gray literature. Outcomes were classified into outcome domains, and common measurement instruments were summarized. Seventeen outcome domains from 140 unique outcomes were identified from 45 included interventions reported in 120 studies. The most frequently collected outcome domains included anthropometry and body composition (91% of included interventions), physical activity (84%), dietary intake (71%), environmental (71%), and sedentary behavior (62%). The most frequently collected outcomes from each of these domains included body mass index (89%), physical activity (73%), fruit and vegetable intake (58%), school environment (42%), and screen time (58%). Outcome measurement instruments varied, particularly for behavioral outcomes. Standardization of reported outcomes and measurement instruments is recommended to facilitate data harmonization and support quantifying broader benefits of CBIs for obesity prevention.

BACKGROUND: System dynamics approaches, including group model building (GMB) and causal loop diagrams (CLDs), can be used to document complex public health problems from a community perspective. This paper aims to apply Social Network Analysis (SNA) methods to combine multiple CLDs created by local communities into a summary CLD, to identify common drivers of the health and wellbeing of children and young people. METHODS: Thirteen community CLDs regarding children and young people health and wellbeing were merged into one diagram involving three steps: (1) combining variable names; (2) CLD merging, where multiple CLDs were combined into one CLD with a set of unique variables and connections; (3) paring, where the Decision-Making Trial and Evaluation Laboratory (DEMATEL) method was used to generate a cut-point to reduce the number of variables and connections and to rank the overall importance of each variable in the merged CLD. RESULTS: Combining variable names resulted in 290 variables across the 13 CLDS. A total of 1,042 causal links were identified in the merged CLD. The DEMATEL analysis of the merged CLD identified 23 common variables with a net importance between 1.0 and 4.5 R + C values and 57 causal links. The variables with the highest net importance were 'mental health' and 'social connection & support' classified as high net receivers of influence within the system. CONCLUSIONS: Combining large CLDs into a simple diagram represents a generalisable model of the drivers of complex health problems.

BACKGROUND: Vocational school students exhibit significant risk behaviors in terms of poor diet, frequent use of nicotine products, inadequate fruit and vegetable intake, low levels of physical activity, and poor mental health. This makes vocational students vulnerable to the development of noncommunicable diseases. Therefore, effective health promotion programs targeting vocational students are required. OBJECTIVE: The Danish study "Data-driven and Systems Approach to Health Promotion Among Vocational Students" (Data Health) aims to develop, implement, and evaluate a systems approach to support vocational schools, municipalities, and local communities in implementing locally relevant health promotion actions among and for vocational students. This paper describes the Data Health program and how implementation and preliminary effectiveness will be evaluated. METHODS: The Data Health program offers an iterative 5-step process to develop changes in the systems that shape health behavior and well-being among vocational students. The program will be implemented and evaluated in 8 Danish vocational schools in 4 municipalities. The implementation of the process and actions will be explored using a systems-based evaluation design that assesses contextual differences and the mechanisms through which the program leads to changes in the systems. Preliminary effectiveness at the individual level (students' self-reported health behavior and well-being) and organizational level (school organizational readiness reported by school staff) will be assessed using a quasi-experimental design, and cross-sectional data will be collected at all 8 schools simultaneously 4 times during the 2-year study period. RESULTS: This study was launched in 2021, and data collection is expected to be completed in June 2024. The first results are expected to be submitted for publication in January 2024. CONCLUSIONS: We expect that the Data Health study will make significant contributions to complex intervention research by contributing to the paucity of research studies that have used systems approaches in school settings. The study will also provide evidence of successful elements for systems change and effectiveness to determine whether a national scale-up can be recommended. TRIAL REGISTRATION: ClinicalTrials.gov NCT05308459; https://clinicaltrials.gov/study/NCT05308459. INTERNATIONAL REGISTERED REPORT IDENTIFIER (IRRID): DERR1-10.2196/52571.
RESUMO
BACKGROUND: Healthy Together Victoria (HTV) was a Victorian Government initiative that sought to reduce the prevalence of overweight and obesity through targeting chronic disease risk factors including physical activity, poor diet quality, smoking, and harmful alcohol use. The intervention involved a boosted workforce of > 170 local-level staff in 12 communities; employed to deliver system activation around health and wellbeing for individuals, families and communities. A cluster randomised trial (CRT) of a systems thinking approach to obesity prevention was embedded within HTV. We present the two-year changes in overweight and obesity and associated behaviours among secondary school students across Victoria, Australia. METHODS: Twenty-three geographically bounded areas were randomised to intervention (12 communities) or comparison (11 communities). Randomly selected secondary schools within each community were invited to participate in the trial in 2014 and 2016. Students in Grade 8 (aged approximately 13-15 years) and Grade 10 (aged approximately 15-16 years) at participating schools were recruited using an opt-out approach across July-September 2014 and 2016. Primary outcomes were body mass index (BMI) and waist circumference. Secondary outcomes were physical activity, sedentary behaviour, diet quality, health-related quality of life, and depressive symptoms. Linear mixed models were fit to estimate the intervention effect adjusting for child/school characteristics. RESULTS: There were 4242 intervention children and 2999 control children in the final analysis. For boys, the two-year change showed improvement in intervention versus control for waist circumference (difference in change: - 2.5 cm; 95% confidence interval [CI]: - 4.6, - 0.5) and consumption of sugar-sweetened beverages per day (< 1 serve: 8.5 percentage points; 95% CI: 0.6, 16.5). For girls, there were no statistically significant differences between conditions. CONCLUSIONS: HTV seemed to produce favourable changes in waist circumference and sugar-sweetened beverage consumption for boys, however, no effect on BMI was observed. Although the HTV intervention was cut short, and the period between data collection points was relatively short, the changes observed in HTV contribute to the growing evidence of whole-of-community interventions targeting childhood obesity. TRIAL REGISTRATION: This trial is unregistered. The intervention itself was a policy setting delivered by government and our role was the collection of data to evaluate the effect of this natural experiment. That is, this study was not a trial from the classical point of view and we were not responsible for the intervention.

Bold and comprehensive action is needed to prevent diet-related diseases in rural areas, which includes improving food environments to enable healthier dietary practices. Rural health services are integral to the health of rural populations, yet their role in community disease prevention is not swell understood. This study sought to understand health service, local government, and food outlet stakeholders' perspectives on (1) the drivers of unhealthy retail environments in a rural setting; (2) the role of rural health services in supporting changes in local food environments; and to (3) identify characteristics of potential interventions. Two Group Model Building workshops were held with health service and local government leaders (n = 9), and interviews were conducted with local food outlet participants (n = 13). Key themes included 'enablers to healthier food environments', 'barriers to healthier food environments', 'Rural health services are a leading broker of knowledge for healthy food environments', and 'characteristics of desirable healthy food environment interventions.'. Rural health services can play a key role in addressing the current barriers to healthy food environments in rural areas. Effective promotion of healthier diets in rural populations will require consideration of key stakeholder perspectives and the development of further evidence on the role that rural health services can play in improving the healthiness of food environments.

BACKGROUND: Tools for measuring adherence to sustainable healthy diets among children and adolescents are lacking. OBJECTIVE: To advance methods for measuring adherence to sustainable healthy diets among children and adolescents by adapting an existing index, compare scores obtained using the original and adapted versions of the index in a sample of Chilean children, and describe the adapted index association with diet characteristics. METHODS: The Planetary Health Diet Index (PHDI) was adapted to better reflect children's and adolescents' nutritional requirements. The adapted index (PHDI-C) comprises 16 components with a maximum score of 150 points. PHDI-C was piloted among a sample of 958 Chilean children (3-6 years) using dietary data collected in 2016 through single 24-h recalls. A decision tree and food disaggregation methodology were developed to guide the calculation of scores. Scores obtained using the original and adapted versions of the index were compared. Linear regression models adjusted by child's gender and age were fitted to explore associations between total PHDI-C score, dietary recall characteristics and nutritional composition of children's diets. RESULTS: PHDI accounted for 75.7% of children's total caloric intake, whereas PHDI-C accounted for 99.6%. PHDI & PHCI-C scores were low among this sample of children; however, mean total score was lower when using PHDI compared to PHDI-C [40.7(12.1) vs 50.1(14.6)]. Children's scores were very low for nuts & peanuts, legumes, dark green vegetables, whole cereals, tubers & potatoes, and added sugars components across both indices, but were higher for dairy products and eggs & white meats components when using the PHDI-C due to adjustments made to ensure nutritional adequacy. Mean total PHDI-C score was significantly lower on weekends and special occasions, and significantly higher when children reported having a special diet (e.g., vegetarian). Total PHDI-C score was negatively associated with total sugars, saturated fats, trans fats, and animal-based protein intake, and positively associated with total protein, plant-based protein, total carbohydrates, and total fibre intake. CONCLUSIONS: This study provides a replicable method for measuring adherence to sustainable healthy diets among children and adolescents that can be used to monitor trends and measure the effectiveness of actions targeting improving children's diets.

Objective: To identify and analyse ongoing nutrition-related surveillance programmes led and/or funded by national authorities in countries in South-East Asian and Western Pacific Regions. Methods: We systematically searched for publications in PubMed® and Scopus, manually searched the grey literature and consulted with national health and nutrition officials, with no restrictions on publication type or language. We included low- and middle-income countries in the World Health Organization South-East Asia Region, and the Association of Southeast Asian Nations and China. We analysed the included programmes by adapting the United States Centers for Disease Control and Prevention's public health surveillance evaluation framework. Findings: We identified 82 surveillance programmes in 18 countries that repeatedly collect, analyse and disseminate data on nutrition and/or related indicators. Seventeen countries implemented a national periodic survey that exclusively collects nutrition-outcome indicators, often alongside internationally linked survey programmes. Coverage of different subpopulations and monitoring frequency vary substantially across countries. We found limited integration of food environment and wider food system indicators in these programmes, and no programmes specifically monitor nutrition-sensitive data across the food system. There is also limited nutrition-related surveillance of people living in urban deprived areas. Most surveillance programmes are digitized, use measures to ensure high data quality and report evidence of flexibility; however, many are inconsistently implemented and rely on external agencies' financial support. Conclusion: Efforts to improve the time efficiency, scope and stability of national nutrition surveillance, and integration with other sectoral data, should be encouraged and supported to allow systemic monitoring and evaluation of malnutrition interventions in these countries.

Research into the link between food environments and health is scarce. Research in this field has progressed, and new comprehensive methods (i.e., incorporating all food retail outlets) for classifying food retail environments have been developed and are yet to be examined alongside measures of obesity. In this study, we examine the association and temporal trends between the food environment and BMI of a repeated cross-sectional sample of the adult population between 2008 and 2016. Methods: Food retail data for 264 postal areas of Greater Melbourne was collected for the years 2008, 2012, 2014, and 2016, and a container-based approach was used to estimate accessibility to supermarkets, healthy and unhealthy outlets. Data on BMI for postal areas was obtained from the Victorian Population Health Survey (n = 47,245). We estimated the association between the food environment and BMI using linear mixed models. Results indicated that BMI increased as accessibility to healthy outlets decreased by up to -0.69 kg/m2 (95%CI: -0.95, -0.44). BMI was lower with high and moderate access to supermarkets compared to low access by -0.33 kg/m2 (-0.63, -0.04) and -0.32 kg/m2 (-0.56, -0.07), and with high access to unhealthy outlets compared to low access (-0.38 kg/m2: -0.64, -0.12) and moderate access (-0.54 kg/m2: -0.78, -0.30). Conclusion: Our results show that increasing access and availability to a diverse range of food outlets, particularly healthy food outlets, should be an important consideration for efforts to support good health. This research provides evidence that Australia needs to follow suit with other countries that have adopted policies giving local governments the power to encourage healthier food environments.

Background: Socioeconomic status is inversely associated with weight status in developed countries. Underlying mechanisms are still to be clarified. Our aim was to determine if weight-related behaviors and health-related quality of life (HRQoL) mediate the relationship between socio-educational advantage and weight status in Australian children 9 to 13 years of age. Methods: Secondary analysis of data collected by two cluster randomized trials (2019 wave). We measured children's (n = 3978) height, weight, diet, physical activity, sedentary behavior, and HRQoL. Socio-.educational advantage was assessed at school level using the Index of Community Socio-Educational Advantage (ICSEA). A counterfactual framework was used to explore potential mediators in the relationship between socio-educational disadvantage and (1) overweight/obesity and (2) BMI z-score (BMIz). Results: Low socio-educational advantage was associated with increased overweight/obesity and BMIz. The overweight/obesity association was mediated by sedentary behavior (natural indirect effect as a proportion of total, 7.5%) sugar-sweetened beverage (SSB) consumption (12.7%), physical functioning (11.9%), psychosocial health (10.9%), school (6.8%) and social functioning (15.6%), and total HRQoL score (13.8%). The ICSEA-BMIz relationship was mediated by sedentary behavior (5.7%), sleep duration (4.1%), SSB (10.6%), physical functioning (9.9%), psychosocial health (9.1%), school (5.5%) and social (13.7%) functioning, and total HRQoL score (11.7%). Conclusion: Victorian Children with low socio-educational advantage were more likely to be living with overweight or obesity. This relationship was mediated by children's sedentary behavior, SSB consumption, and HRQoL. Trial Registration: Australian New Zealand Clinical Trials Registry (ANZCTR): ACTRN12616000980437 (registered July 26, 2016, retrospectively registered) and ACTRN12618001986268 (registered December 11, 2018, prospectively registered). https://www.anzctr.org.au/Trial/Registration.
RESUMO
INTRODUCTION: Climate change impacts mental wellbeing through complex pathways and young people are among the most vulnerable to climate-related anxiety. Minding our Futures used methods from systems science to explore this issue and identify actions to promote mental wellbeing for young Australians (18-24 years). METHODS: This qualitative study used Group Model Building via three online facilitated workshops recruiting health, youth and climate practitioners and researchers engaged with young people around climate change and/or mental wellbeing (N = 14). Analysis created a systems map and rich description of the relationships between causal factors and their impact on young people. RESULTS: Three themes emerged; "Government, Services and Structures" highlighted underlying structural issues including capitalism and political powerlessness; "Social Norms, Communication and Taking Action" reflected social media and misinformation; and "Personal Experience of Environmental Disasters" described the impact of climate-related disasters and importance of nature and place connection. Participants specified connections between the themes and mental health outcomes. CONCLUSION: This novel applied translational research process supported key informants to design structural responses to a complex and critical public health issue. Their vision was a multi-faceted approach, co-led with young people, drawing on Indigenous knowledges and change-focused policy, community empowerment and nature-based interventions.

Frequent potentially avoidable presentations to Emergency Departments (EDs) represent a complex problem, driven by multiple interdependent and interacting factors that change over time and influence one another. We sought to describe and map the drivers of frequent potentially avoidable presentations to a regional ED, servicing regional and rural areas, and identify possible solutions from the perspectives of key stakeholders. This study used a qualitative, community-based systems dynamics approach utilising Group Model Building (GMB). Data were collected from two 3-h online workshops embedded with small-group discussions and conducted with stakeholder groups operating within a regional health system. Stakeholders were guided through a series of participatory tasks to develop a causal loop diagram (CLD) using Systems Thinking in Community Knowledge Exchange software (n=29, workshop one), identify potential action points and generate a prioritised action list to intervene in the system (n=21, workshop two). Data were collected through note taking, real-time system mapping, and recording the workshops. Each action was considered against the Public Health 12 framework describing twelve leverage points to intervene in a system. A CLD illustrating the complex and interrelated factors that drive frequent potentially avoidable ED presentations was developed and classified into four categories: (1) access to services; (2) coordination; (3) patient needs; and (4) knowledge and skills. Nine action areas were identified, with many relating to care and service coordination. Most actions aligned with lower-level system impact actions. This study provides an in-depth understanding of influencing factors and potential solutions for frequent potentially avoidable ED presentations across a regional health system. The CLD demonstrates frequent potentially avoidable ED presentations are a complex problem and identified that a prevention response should engage with system- and individual-level solutions. Further work is needed to prioritise actions to support the implementation of higher-level system impacts.

Introduction: Food environments are a key determinant of food intake and diet-related health. This paper describes the development of an iterative, adaptive, context-specific framework for health-enabling food environments embedded in cocreation theory. Methods: A 3-stage multimethod framework for the coproduction and prototyping of public health interventions was followed in an iterative manner during the development of the framework. These 3 stages were (1) evidence review, including systematic review, consultation with experts, and observation of current work; (2) codesign of the framework prototype with multiple stakeholders; and (3) coproduction through refinement of the prototype through stakeholder workshops and expert reviews with incorporation of researcher notes and workshop evaluation. We use the term prototype during the development phase and the term framework to report on the final product. Results: COACH (CO-creation and evaluation of food environments to Advance Community Health) is a process framework that describes what best practice application of cocreation in health-enabling food retail environments should involve. COACH consists of 10 interdependent factors within a 4-phase continuous quality improvement cycle. The 4 phases of the cycle are engagement and governance establishment, communication and policy alignment, codesign and implementation, and monitoring and evaluation. Conclusions: Utilizing cocreation theory represents an innovative step in research and practice to improve the healthiness of food retail environments. COACH provides a specific, unique, and comprehensive guide to the utilization of cocreation to improve the healthiness of food environments in practice.
RESUMO
It has increasingly been recognized that developing successful obesity prevention policies and interventions requires understanding of the complex mechanisms driving the obesity pandemic and that models could be useful tools for simulating policies. This paper reviews system dynamics simulation models of mechanisms driving childhood overweight and obesity and/or testing of preventive interventions. A systematic literature search was conducted in six databases from inception to January 2023 using terms related to overweight/obesity, children, and system dynamics. Study descriptives, mechanisms, and where to intervene (the leverage points), as well as quality assessments of the simulation models were extracted by two researchers into a predetermined template and narratively synthesized. Seventeen papers describing 15 models were included. Models describing the mechanisms ranged from only intrapersonal factors to models cutting across multiple levels of the ecological model, but mechanisms across levels were lacking. The majority of interventions tested in the simulation models were changes to existing model parameters with less emphasis on models that alter system structure. In conclusion, existing models included mechanisms driving youth obesity at multiple levels of the ecological model. This is useful for developing an integrated simulation model combining mechanisms at multiple levels and allowing for testing fundamental system changes.

BACKGROUND: World-wide, health service providers are moving towards innovative models of clinical home-based care services as a key strategy to improve equity of access and quality of care. To optimise existing and new clinical home-based care programs, evidence informed approaches are needed that consider the complexity of the health care system across different contexts. METHODS: We present a protocol for working with health services and their partners to perform rapid identification, prioritisation, and co-design of content-appropriate strategies to optimise the delivery of healthcare at home for older people in rural and regional areas. The protocol combines Systems Thinking and Implementation Science using a Consensus Mapping and Co-design (CMC) process delivered over five workshops. DISCUSSION: The protocol will be implemented with rural and regional healthcare providers to identify digital and non-digital solutions that have the potential to inform models of service delivery, improve patient experience, and optimise health outcomes. The combination of system and implementation science is a unique approach for optimising healthcare at home for older populations, especially in the rural context where need is high. This is the first protocol to integrate the use of systems and implementation science into one process and articulating these methods will help with replicating this in future practice.
