Summary: Increasing the healthiness of food retail environments is an identified mechanism to help halt rising rates of diet‐related non‐communicable diseases. Previous studies on healthy food environment adoption report that retailers' perceptions of loss of profitability and higher food costs are often barriers to change. Despite this, actual changes to profitability and food costs have not been fully explored. This study aimed to systematically scope the evidence relating to changes to food costs or profitability when changes are made to increase the healthiness of food and drinks sold by food service retailers. Nine databases were searched, with studies included from settings that sold ready‐to‐consume items, with interventions to increase the healthiness of menus, and reporting food environment/nutrition outcomes, and cost/profit outcomes. Of the 12 studies included, the majority were conducted in the United States and in school settings. Most studies indicated that increasing the healthiness of food service retail environments resulted in neutral or favorable financial outcomes. Food costs and/or profit changes were most often monitored via simple accounting measures. While further research is needed to strengthen the evidence on financial outcomes of healthier food provision, this review indicates that some perceived barriers to change may not be warranted.

Objective: Prevention programs for eating disorders (EDs) and high body index mass (BMI) have the potential to reduce the onset of these interconnected public health concerns. However, it remains unclear whether routine implementation of such programs would be cost‐effective. This study aims to determine the cost‐effectiveness of an intervention that aims to prevent both ED and high BMI. Method: A Markov model was developed to evaluate the incremental cost‐effectiveness of a targeted school‐based program, Healthy Weight, that aims to prevent both EDs and high BMI among Australian adolescents with body image concerns (aged 15–18 years), versus a "no intervention" comparator. A cost‐utility analysis was conducted from a "healthcare and education" sector perspective with costs (measured in 2019 Australian dollars) and health impacts modeled over the lifetime of the target population. An incremental cost‐effectiveness ratio (ICER), expressed as cost per health‐adjusted life year (HALY) gained, was calculated. Sensitivity analyses were done to test model assumptions. Results: The mean intervention cost and HALYs gained were AUD$2.13 million (95% CI, AUD$1.83–2.43 million) and 146 (95% CI, 90–209), respectively. With healthcare cost‐savings (AUD$3.97 million) included, the intervention was predicted to be cost‐saving (AUD$1.83 million; 95% CI, AUD$0.51–3.21 million). Primary findings were robust to extensive sensitivity analyses. Discussion: The Healthy Weight intervention is likely to represent good value‐for‐money. To ensure the successful implementation of this program at the population level, further research on its feasibility and acceptability among schools and the wider community is required.

Background: Evaluating sugar-sweetened beverage (SSB) taxation often relies on simulation models. We assess how assumptions about the response to SSB taxation affect the projected body weight change and subsequent health and economic impacts related to type 2 diabetes mellitus (T2DM) using Germany as an example. Methods: In the main analysis, we estimated changes in energy intake by age and sex under a 20% value-added tax on SSBs in Germany using marginal price elasticities (PE) and applied an energy equilibrium model to predict body weight changes. We then quantified the impact of several assumption modifications: SSB own-PE adjusted for consumption (M1)/based on alternative meta-analysis (M2); SSB consumption adjusted for underreporting (M3); substitution via marginal (M4a) or adjusted (M4b) cross-PE/as % of calorie change (M4c). We also assessed scenarios with alternative tax rates of 10% (S1) or 30% (S2) and including fruit juice (S3). We calculated overweight and obesity rates per modification and scenario. We simulated the impact on T2DM, associated healthcare costs, and disability-adjusted life years (DALYs) over the lifetime of the 2011 German adult population with a Markov model. Data included official demographics, national surveys, and meta-analyses. Results: A 20% value-added tax in Germany could reduce the number of men and women with obesity by 210,800 [138,800; 294,100] and 80,800 [45,100; 123,300], respectively. Over the population's lifetime, this would lead to modest T2DM-related health and economic impacts (76,700 DALYs [42,500; 120,600] averted; €2.37 billion [1.33; 3.71] costs saved). Policy impacts varied highly across modifications (all in DALYs averted): (M1) 94,800 [51,500; 150,700]; (M2) 164,200 [99,500; 243,500]; (M3) 52,600 [22,500; 91,100]; (M4a) -18,100 [-111,500; 68,300]; (M4b) 25,800 [-31,400; 81,500]; (M4c) 46,700 [25,300; 77,200]. The variability in policy impact related to modifications was similar to the variability between alternative policy scenarios (all in DALYs averted): (S1) 26,400 [9,300; 47,600]; (S2) 126,200 [73,600; 194,500]; (S3) 342,200 [234,200; 430,400]. Conclusions: Predicted body weight reductions under SSB taxation are sensitive to assumptions by researchers often needed due to data limitations. Because this variability propagates to estimates of health and economic impacts, the resulting structural uncertainty should be considered when using results in decision-making.

Objectives: This study analyses Australian healthy hospital retail policies to identify the similarities and differences in the policies and policy implementation processes across jurisdictions and to examine the potential impact of different policy components on dietary behaviours. Study type: Policy analysis and scoping review. Methods: Healthy retail policy documents and policy implementation guidelines for public healthcare facilities were identified via a grey literature search of health department websites in all Australian jurisdictions. Policy components and policy implementation processes were extracted and analysed for similarities and differences. The potential effectiveness of the different policy components on purchasing and/or dietary behaviours was identified via a scoping review of the academic literature, conducted in March 2023 across seven electronic databases and Google Scholar. The scoping review included studies reporting the impacts of healthy food retail interventions implemented in hospitals. No timeframe restriction was applied for either the grey literature search or the scoping review. Results: All Australian state and territory jurisdictions except the state of Tasmania have implemented jurisdiction-specific healthy retail policies in public hospital settings. There are similarities and differences in the policy components and implementation design across jurisdictions. Similarities include the policy scope, the use of a traffic-light system to classify the nutritional healthiness of food and beverages for sale, and the standards used to determine the mix of healthy and unhealthy food availability. These similarities allowed the sharing of resources across some jurisdictions. There is limited evaluation of policy impacts on purchase and/or consumption behaviours. Twenty of 27 studies identified via the scoping literature review examined interventions similar to the Australian policies and showed that these policies could result in increased purchase of healthier products among hospital staff and visitors. Key implementation success factors include strong support for the policy from all stakeholders, practical implementation support resources, and impacts on retailer profitability. Conclusions: The healthy hospital retail policies implemented across Australian jurisdictions could encourage healthier food and beverage purchases among staff and visitors. Evaluation of the policies could facilitate further refinement to enhance the effectiveness of the policies and translation of learnings to international contexts. [ABSTRACT FROM AUTHOR]

Objective and importance of study: Overweight and obesity are the second leading risk factors for death and non-communicable disease in Australia. This study aimed to examine the Australian Federal Government funding landscape for population-level obesity prevention from 2013 to 2022. Study type: A retrospective analysis and narrative synthesis of publicly available data on obesity prevention funding from the Federal Government and major federally funded Australian research organisations. Methods: Searches were conducted of Australian Federal Government Budget documents and funding announcements from the National Health and Medical Research Council (NHMRC), Australian Research Council (ARC) and Medical Research Future Fund (MRFF). Funding allocations targeting obesity prevention, or the prevention of risk factors associated with obesity, were included. These were determined by the presence of keywords related to obesity, unhealthy diet, physical activity and sedentary behaviour. Data were extracted verbatim, coded and narratively synthesised by funding source. Results: From 2013 to 2022, 186 funding allocations for obesity prevention in Australia were identified, totalling approximately A$778 million. The proportion of funding allocated to obesity prevention compared to the total annual budget of each funding source was relatively low: NHMRC = 1.1%; ARC = 0.2%; MRFF = 0.8%; Federal Government = 0.1% (of health budget). Funding for obesity prevention initiatives fluctuated over time. Conclusions: Findings underscore the need for strategic and ongoing funding allocation to support obesity prevention research, implementation and sustainment of evidence-based obesity prevention initiatives in Australia.

Summary: Background: Childhood obesity prevention initiatives are complex interventions that aim to improve children's obesity‐related behaviors and provide health promoting environments. These interventions often impact individuals, communities, and outcomes not primarily targeted by the intervention or policy. To accurately capture the effectiveness and cost‐effectiveness of childhood obesity prevention interventions, an understanding of the broader impacts (or spillover effects) is required. This systematic review aims to assess the spillover effects of childhood obesity prevention interventions. Methods: Six academic databases and two trial registries were searched (2007–2023) to identify studies reporting quantifiable obesity‐related and other outcomes in individuals or communities not primarily targeted by an obesity prevention intervention. Critical appraisal was undertaken for studies that reported statistically significant findings, and a narrative synthesis of the data was undertaken. Results: Twenty academic studies and 41 trial records were included in the synthesis. The most commonly reported spillovers were diet or nutrition‐related, followed by BMI and physical activity/sedentary behavior. Spillovers were mostly reported in parents/caregivers followed by other family members. Nine of the 20 academic studies reported statistically significant spillover effects. Conclusion: Limited evidence indicates that positive spillover effects of childhood obesity prevention interventions can be observed in parents/caregivers and families of targeted participants.

Dental caries is the most prevalent oral disease across the life course. This study modeled the population health and economic impact of a 20% sugar sweetened beverages tax (SSB) for preventing dental caries compared to no intervention (societal and healthcare perspective). A cost-effectiveness analysis according to quintiles of area-level socioeconomic disadvantage was performed for the 2020 Australian population (0-100 years old) using a closed cohort Markov model. A qualitative assessment of implementation considerations (e.g., acceptability, equity, sustainability) was undertaken. Health outcomes were modeled as decayed teeth prevented and disability-adjusted life years (DALYs) averted. The 10-year and lifetime scenarios were modeled with probabilistic sensitivity analysis (Monte Carlo simulation, 2000 cycles). The 10-year scenario from a societal perspective yielded cost-savings of AUD$63.5M, healthcare cost-savings of AUD$42.2M, 510,977 decayed teeth averted and 98.1 DALYs averted. The lifetime scenario resulted in societal cost savings of AUD$176.6M, healthcare cost-savings of AUD$122.5M, 1,309,211 decayed teeth averted and 254.9 DALYs averted. Modeling indicated 71.5% and 74.5% cost-effectiveness for the 10-year and lifetime scenarios, respectively. A three-fold health benefit for the least advantaged was found compared to the most advantaged. A 20% SSB tax in Australia is cost-effective and promotes health equity. [ABSTRACT FROM AUTHOR]
