A protocol of a pilot randomised trial (Action-RESPOND) to support rural and regional communities with implementing community-based systems thinking obesity prevention initiatives.

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.

Minding our futures: Understanding climate-related mental wellbeing using systems science.

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.

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.

Understanding weight status and dietary intakes among Australian school children by remoteness: a cross-sectional study.

OBJECTIVE: To determine whether primary school children's weight status and dietary behaviours vary by remoteness as defined by the Australian Modified Monash Model (MMM). DESIGN: A cross-sectional study design was used to conduct secondary analysis of baseline data from primary school students participating in a community-based childhood obesity trial. Logistic mixed models estimated associations between remoteness, measured weight status and self-reported dietary intake. SETTING: Twelve regional and rural Local Government Areas in North-East Victoria, Australia. PARTICIPANTS: Data were collected from 2456 grade 4 (approximately 9-10 years) and grade 6 (approximately 11-12 years) students. RESULTS: The final sample included students living in regional centres (17·4 %), large rural towns (25·6 %), medium rural towns (15·1 %) and small rural towns (41·9 %). Weight status did not vary by remoteness. Compared to children in regional centres, those in small rural towns were more likely to meet fruit consumption guidelines (OR: 1·75, 95 % CI (1·24, 2·47)) and had higher odds of consuming fewer takeaway meals (OR: 1·37, 95 % CI (1·08, 1·74)) and unhealthy snacks (OR = 1·58, 95 % CI (1·15, 2·16)). CONCLUSIONS: Living further from regional centres was associated with some healthier self-reported dietary behaviours. This study improves understanding of how dietary behaviours may differ across remoteness levels and highlights that public health initiatives may need to take into account heterogeneity across communities.

Healthy weight, health behaviours and quality of life among Aboriginal children living in regional Victoria.

OBJECTIVE: To report the prevalence of healthy weight and related behaviours among Victorian Aboriginal and non-Aboriginal children and explore associations between these factors and health-related quality of life (HRQoL). METHODS: Analysis of cross-sectional data from two cluster randomised controlled trials using logistic and linear mixed models. The sample included Aboriginal (n=303) and non-Aboriginal (n=3,026) children aged 8-13 years. RESULTS: More than two-thirds of Aboriginal children met guidelines for fruit (75.9%), sweetened drinks (66.7%), sleep (73.1%), screen time (67.7%) and objectively measured physical activity (83.6%); and 79.1% reported consuming take-away foods less than once per week. Aboriginal children were more likely to meet vegetable consumption guidelines (OR=1.42, 95%CI: 1.05, 1.93), but less likely to have a healthy weight (OR=0.66, 95%CI: 0.52, 0.85) than non-Aboriginal children. Mean HRQoL scores were significantly higher among non-Aboriginal children and both Aboriginal and non-Aboriginal children meeting health guidelines. CONCLUSIONS: Most Aboriginal children in this study met guidelines for fruit, physical activity, screen time and sleep, and those meeting these guidelines had significantly higher HRQoL. IMPLICATIONS FOR PUBLIC HEALTH: Promoting nutrition, physical activity and sleep is likely to benefit all children. Aboriginal community-controlled organisations can use these data to design culturally-specific programs that may improve disparities in healthy weight and HRQoL.

Generating change through collective impact and systems science for childhood obesity prevention: The GenR8 Change case study.

BACKGROUND: Community-based interventions have shown promise in reducing childhood overweight and obesity. However, they have been critiqued for using linear logic models. Participatory community-based systems approaches are posited as addressing the complexity of non-linear relationships in a local context. Community members are empowered to understand and describe obesity causation, identify and prioritise possible solutions. The application of such approaches to childhood obesity is in its infancy. AIM: To describe the first 12 months of a participatory whole-of-community systems approach to creating collective action to tackle childhood obesity, called GenR8 Change, in a local government area of Victoria, Australia. METHODS: Three group model building (GMB) sessions focused on the development of a causal loop diagram (CLD), prioritised evidence-informed actions, and developed implementation strategies. The collective impact framework underpinned the approach, with a local backbone group supporting community members to implement prioritised actions. RESULTS: The first two GMB sessions included 20 key community leaders where a CLD examining the factors contributing to childhood obesity in the community was constructed and refined (22 variables GMB1, 53 variables GMB2). In the third session, 171 members of the wider community further refined the CLD, identified priorities for childhood obesity prevention (72 variables in final CLD). One-hundred and thirteen individuals signed up across 13 working groups to plan and implement 53 prioritised actions. Agreed community actions included creating sugar free zones; developing healthy policies; increasing breastfeeding rates; improving drinking water access; and increasing physical activity options. Twelve months post-GMB3, 115 actions had been implemented. CONCLUSION: GenR8 Change is one of the first communities to apply systems thinking to childhood obesity prevention. Knowledge on how to collectively identify relevant leverage points to tackle childhood obesity can now be shared with other communities.

Participatory research with a rural Aboriginal Community Controlled Health Organisation: lessons learned using the CONSIDER statement.

CONTEXT: In Australia, Aboriginal Community Controlled Health Organisations (ACCHOs) are geographically proximal to where Aboriginal and Torres Strait Islander People reside and are valued for providing holistic and culturally safe primary health care. Partnering with ACCHOs in research is appropriate for redressing health inequities experienced by Aboriginal and Torres Strait Islander People, which includes a high burden of chronic disease. Historically, some approaches to Aboriginal and Torres Strait Islander health research have been unethical. Greater accountability in the research process, transparency in reporting, and use of culturally appropriate research methodologies are key recommendations to improving the ethical integrity of research. The need for strengthening the reporting of health research involving Aboriginal and Torres Strait Islander People and Indigenous peoples globally led to the development of the CONSolIDated critERia for strengthening the reporting of health research involving Indigenous peoples (CONSIDER statement), which is a synthesis of international ethical guidelines. This project report uses the CONSIDER statement to critically reflect on participatory research undertaken in partnership with an ACCHO in the rural context and to identify lessons of value for future research. ISSUE: By using the CONSIDER statement as a tool for critical reflection, it was identified that processes used to establish a research partnership with an ACCHO were key to setting the research agenda, including identifying ethical issues, the needs of local Aboriginal and Torres Strait Islander People, and expectations from the research. The participation of Aboriginal community members throughout the entire research process was not only methodologically important but was also ethically appropriate. Research activities in this project included opportunities for Aboriginal community members to directly share their perspectives and experiences and develop local solutions to issues affecting them. Outcomes included evidence to support future funding applications, community-derived priorities that assisted with government reporting, and locally identified methods for addressing chronic disease management. Key to this was building the research capacity and capability of local Aboriginal community members, which also reflected the ethical principles of reciprocity and equity. This also provided opportunities for non-Indigenous researchers to learn from local Aboriginal community members and develop skills in culturally appropriate research. LESSONS LEARNED: Using the CONSIDER statement was beneficial in enabling researchers to critically reflect on a participatory research project undertaken in partnership with a rural ACCHO. Researchers identified that participatory approaches can be used to generate research of relevance to local Aboriginal community members and their ACCHOs, and to support health service reporting, and future funding applications. Research timelines and activities needed to be flexible and adaptable, to allow for staff turnover and unforeseen events of cultural significance. Similarly, it is important for researchers to be receptive to change and open to learning. Although research partnerships are established on trust and mutual respect, it is recommended that greater formal provisions are required to protect the intellectual property of Aboriginal and Torres Strait Islander communities involved in research. These lessons are likely to be transferrable to other settings and are of value to researchers seeking to partner with ACCHOs in research.

Tracking implementation within a community-led whole of system approach to address childhood overweight and obesity in south west Sydney, Australia.

BACKGROUND: Obesity is a chronic disease that contributes to additional comorbidities including diabetes, kidney disease and several cancers. Change4Campbelltown implemented a 'whole of system' approach to address childhood overweight and obesity. We present methods to track implementation and stakeholder engagement in Change4Campbelltown. METHODS: Change4Campbelltown aimed to build capacity among key leaders and the broader community to apply techniques from systems thinking to develop community-led actions that address childhood obesity. Change4Campbelltown comprised development of a stakeholder-informed Causal Loop Diagram (CLD) and locally-tailored action plan, formation of key stakeholder and community working groups to prioritise and implement actions, and continuous monitoring of intervention actions. Implementation data included an action register, stakeholder engagement database and key engagement activities and were collected quarterly by the project management team over 2 years of reporting. RESULTS: Engagement activities increased level of community engagement amongst key leaders, the school-sector and community members. Community-led action increased as engagement increased and this action is mapped directly to the primary point of influence on the CLD. As action spread diversified across the CLD, the geographical spread of action within the community increased. CONCLUSIONS: This paper provides a pragmatic example of the methods used to track implementation of complex interventions that are addressing childhood overweight and obesity.

The Impact of COVID-19 on Rural Food Supply and Demand in Australia: Utilising Group Model Building to Identify Retailer and Customer Perspectives.

Prior to the 2020 outbreak of COVID-19, 70% of Australians' food purchases were from supermarkets. Rural communities experience challenges accessing healthy food, which drives health inequalities. This study explores the impact of COVID-19 on food supply and purchasing behaviour in a rural supermarket. Group model building workshops explored food supply experiences during COVID-19 in a rural Australian community with one supermarket. We asked three supermarket retailers "What are the current drivers of food supply into this supermarket environment?" and, separately, 33 customers: "What are the current drivers of purchases in this supermarket environment?" Causal loop diagrams were co-created with participants in real time with themes drawn afterwards from coded transcripts. Retailers' experience of COVID-19 included 'empty shelves' attributed to media and government messaging, product unavailability, and community fear. Customers reported fear of contracting COVID-19, unavailability of food, and government restrictions resulting in cooking more meals at home, as influences on purchasing behaviour. Supermarket management and customers demonstrated adaptability and resilience to normalise demand and combat reduced supply.

Protocol for the measurement of changes in knowledge and engagement in the stepped wedge cluster randomised trial for childhood obesity prevention in Australia: (Reflexive Evidence and Systems interventions to Prevent Obesity and Non-communicable Disease (RESPOND)).

BACKGROUND: Community-based interventions have shown promise in addressing the childhood obesity epidemic. Such efforts rely on the knowledge of key community members and their engagement with the drivers of obesity in their community. This paper presents the protocol for the measurement and evaluation of knowledge and engagement among community leaders within a whole-of-community systems intervention across 10 large intervention communities in Australia. METHODS: We will investigate the role of stakeholder knowledge and engagement in the implementation and effectiveness of the stepped wedge cluster randomised trial in ten communities in Victoria, Australia. Data will be collected using the Stakeholder-driven Community Diffusion Survey (SDCD) to measure levels of knowledge and engagement prior to commencement (2019), across the three separate levels of governance within the intervention at five time points. Primary outcomes will be baseline overall knowledge and engagement scores across the three levels of governance and change in overall knowledge and engagement over time. DISCUSSION: We hypothesise there will be heterogeneity between intervention sites on levels of knowledge and engagement and that these differences will be associated with variability in implementation success.

Composition of objectively measured physical activity and sedentary behaviour participation across the school-day, influence of gender and weight status: cross-sectional analyses among disadvantaged Victorian school children.

BACKGROUND: The after-school period has been described as the 'critical window' for physical activity (PA) participation. However, little is known about the importance of this window compared with the before and during-school period among socioeconomically disadvantaged children, and influence of gender and weight status. METHODS: 39 out of 156 (RR=25%) invited primary schools across 26 local government areas in Victoria, Australia, consented to participate with 856 children (RR=36%) participating in the wider study. The analysis sample included 298 Grade 4 and Grade 6 children (mean age: 11.2±1.1; 44% male) whom met minimum accelerometry wear-time criteria and had complete height, weight and health-behaviours questionnaire data. Accelerometry measured duration in daily light-intensity PA (LPA), moderate-to-vigorous PA (MVPA) and sedentary time (ST) was calculated for before-school=8-8:59, during-school=9:00-15:29 and after-school=15:30-18:00. Bivariate and multivariable linear regression analyses were conducted. RESULTS: During-school represented the greatest accumulation of LPA and MVPA compared with the before and after-school periods. Boys engaged in 102 min/day of LPA (95% CI 98.5 to 104.9) and 62 min/day of MVPA (95% CI 58.9 to 64.7) during-school; girls engaged in 103 min/day of LPA (95% CI 99.7 to 106.5) and 45 min/day of MVPA (95% CI 42.9 to 47.4). Linear regression models indicated that girls with overweight or obesity engaged in significantly less LPA, MVPA and more time in ST during-school. CONCLUSIONS: This study highlights the importance of in-school PA compared with after-school PA among socioeconomically disadvantage children whom may have fewer resources to participate in after-school PA.
