How much is invested in obesity prevention in Australia? An analysis of major research and Federal Government funding, 2013-2022.

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.

Consumer preferences for attributes in sweet beverages and market impacts of beverage innovation.

Consumption of sugar-sweetened beverages (SSB) is considered as an important risk factor for the development of overweight and obesity in populations worldwide, with a particular focus on the risks in the younger parts of the population - children and adolescents. Together with fiscal measures and information tools, innovation-based approaches such as the development of sugar-free or sugar-reduced versions of established beverages and development of new beverage products have been used to reduce this challenge, but the effects of product innovation on sugar intake are not well understood from the literature, as previous studies have largely ignored substitution effects of product innovation in the beverage domain. The objective of the present study was to investigate the potential effectiveness of product innovation as a strategy to affect consumers' intake of energy from sweetened non-alcoholic beverages. Using household panel shopping data from approximately 3000 Danish households over the years 2006-2014, we developed a hedonic pricing approach to estimate the influence of product attributes on consumers' utility, based on observed data for Danish households' purchases of sweet drinks. Overall, the study found that beverages' degree of sweetness positively affected the satiation effect of beverage consumption and in turn made the demand for these beverages less sensitive to e.g. price changes or introduction of competing products, whereas the energy density of the beverages positively affected the demand sensitivity to market changes. Findings like these can be useful for assessing market effects as well as environmental and public health impacts of changes to the market environment.

Evaluation of the population-level impacts of the LiveLighter® obesity prevention campaign from 2012 to 2019 based on serial cross-sectional surveys.

BACKGROUND: Halting and reversing the upward trend in obesity requires sustained implementation of comprehensive, evidence-based strategies at the population-level. The LiveLighter® program targets adults using a range of public education strategies, including mass media campaigns, to support healthy lifestyle changes to attain or maintain a healthy weight and reduce the risk of chronic disease. LiveLighter® has been implemented in Western Australia (WA) since 2012 and, to our knowledge, includes the longest running adult-targeted mass media campaign for healthy weight and lifestyle promotion and education globally. This evaluation assessed the impact of LiveLighter® on WA adults' knowledge, intentions and behaviours as they relate to healthy eating and body weight from 2012 to 2019. METHODS: LiveLighter® mass media campaigns, which are TV-led and aired statewide, depict genuine, graphic imagery of visceral fat around internal organs to raise awareness about the link between excess body weight and chronic diseases; demonstrate how unhealthy food and drink consumption can contribute to unhealthy weight gain; and recommend healthy alternatives. Cross-sectional telephone surveys were conducted at baseline and following each campaign phase with an independent, randomly selected sample of WA adults aged 25 to 49 years (n = 501 to n = 1504 per survey) to assess their knowledge of the link between excess body weight and chronic diseases, and their intentions and behaviours related to healthy eating and weight. Multivariable logistic regression models were undertaken to assess differences in responses between baseline and each post-campaign survey. RESULTS: Compared to baseline, there were significant increases in the proportion of respondents reporting knowledge of excess body weight as a risk factor for certain cancers and type 2 diabetes, intentions to eat more fruit and vegetables and drink less sugar sweetened beverages (SSBs) in the next seven days, and the proportion of respondents who reported meeting guidelines for daily vegetable intake. Reported consumption of SSBs significantly decreased. CONCLUSIONS: LiveLighter® is associated with improvements in knowledge of the health risks associated with excess body mass, increased vegetable intake and reduced SSB consumption in WA adults. These findings support the use of sustained, well-designed healthy lifestyle promotion and education programs as part of a comprehensive obesity prevention strategy.

The Role of Parental Adherence to the Mediterranean Diet and Family Time Together in Children's Weight Status: The BeE-School Project.

The family context has been associated with children's weight status. This study aims to investigate the association of parents' adherence to the Mediterranean diet and family time with the weight status of children. The research is part of BeE-school, a cluster-randomized trial implemented in primary schools located in socially vulnerable contexts. A total of 735 children (380 boys and 355 girls) aged 6 to 10 participated in the study. Anthropometrics were assessed during school time, and weight status was categorized, while parents self-reported sociodemographic variables, adherence to the Mediterranean diet (MEDAS questionnaire), and family time. Children from families with higher education levels whose parents have a high adherence to the Mediterranean diet have lower odds of overweight/obesity (odds ratio (OR) 0.301, 95% CI 0.143-0.634, p = 0.002). Also, children from families with lower education levels who have more time together with their family have lower odds of overweight/obesity (OR 0.731, 95% CI 0.573-0.934, p = 0.012). The family environment, mainly family time together and adherence to the Mediterranean diet, exerts a significant influence on children's weight status. Professionals working in children's health should consider the family when fostering health-promoting behaviors.

Postnatal Consumption of Black Bean Powder Protects against Obesity and Dyslipidemia in Male Adult Rat Offspring from Obese Pregnancies.

The adverse influence of maternal obesity on offspring metabolic health throughout the life-course is a significant public health challenge with few effective interventions. We examined if black bean powder (BBP) supplementation to a high-calorie maternal pregnancy diet or a postnatal offspring diet could offer protection against the metabolic programming of metabolic disease risk in adult offspring. Female Sprague Dawley rats were randomly assigned to one of three diets (n = 10/group) for a 3-week pre-pregnancy period and throughout gestation and lactation: (i) a low-caloric control diet (CON); (ii) a high-caloric obesity-inducing diet (HC); or (iii) the HC diet with 20% black bean powder (HC-BBP). At weaning [postnatal day (PND) 21], one male pup from each dam was weaned onto the CON diet throughout the postnatal period until adulthood (PND120). In addition, a second male from the HC group only was weaned onto the CON diet supplemented with BBP (CON-BBP). Thus, based on the maternal diet exposure and offspring postnatal diet, four experimental adult offspring groups were compared: CON/CON, HC/CON, HC-BPP/CON, and HC/CON-BBP. On PND120, blood was collected for biochemical analysis (e.g., lipids, glycemic control endpoints, etc.), and livers were excised for lipid analysis (triglycerides [TG] and cholesterol) and the mRNA/protein expression of lipid-regulatory targets. Compared with the CON/CON group, adult offspring from the HC/CON group exhibited a higher (p < 0.05) body weight (BW) (682.88 ± 10.67 vs. 628.02 ± 16.61 g) and hepatic TG (29.55 ± 1.31 vs. 22.86 ± 1.85 mmol/g). Although maternal BBP supplementation (HC-BBP/CON) had little influence on metabolic outcomes, the consumption of BBP in the postnatal period (HC/CON-BBP) lowered hepatic TG and cholesterol compared with the other treatment groups. Reduced hepatic TG in the HC/CON-BBP was likely associated with lower postnatal BW gain (vs. HC/CON), lower mRNA and protein expression of hepatic Fasn (vs. HC/CON), and lower serum leptin concentration (vs. CON/CON and HC groups). Our results suggest that the postnatal consumption of a black-bean-powder-supplemented diet may protect male rat offspring against the programming of obesity and dyslipidemia associated with maternal obesity. Future work should investigate the bioactive fraction of BBP responsible for the observed effect.

Dietary intake of whole king oyster mushroom (Pleurotus eryngii) attenuated obesity via ameliorating lipid metabolism and alleviating gut microbiota dysbiosis.

There is a growing interest in employing whole food-based strategies to prevent chronic diseases, owing to the potential synergistic interactions among various bioactive components found within whole foods. The current research aimed to determine inhibitory effects of the whole edible mushroom Pleurotus eryngii (WPE) on high-fat diet (HFD)-induced obesity in mice. Our results showed that dietary intake of WPE significantly inhibited the abnormal gain of body weight and adipose tissue weight, improved glucose tolerance, and ameliorated the serum biochemical parameters in HFD-fed mice. The histological analysis illustrated that the severity of non-alcoholic fatty liver induced by HFD was significantly reduced by WPE. Oral intake of WPE profoundly modulated the mRNA levels of hepatic genes involved in lipid metabolism and also increased the level of short-chain fatty acids in the mouse cecum. Moreover, WPE alleviated the HFD-induced gut microbiota dysbiosis, increasing the abundance of beneficial bacteria (Akkermansia, Lactobacillus, Bifidobacterium, and Sutteralla), and decreasing the harmful ones (rc4-4, Dorea, Coprococcus, Oscillospira, and Ruminococcus). These findings presented new evidence supporting that WPE could be used as a whole food-based strategy to protect against obesity and obesity-driven health problems.

Food deserts exposure, density of fast-food restaurants, and park access: Exploring the association of food and recreation environments with obesity and diabetes using global and local regression models.

To prevent obesity and diabetes environmental interventions such as eliminating food deserts, restricting proliferation of food swamps, and improving park access are essential. In the United States, however, studies that examine the food and park access relationship with obesity and diabetes using both global and local regression are lacking. To guide county, state, and federal policy in combating obesity and diabetes, there is a need for cross-scale analyses to identify that relationship at national and local levels. This study applied spatial regression and geographically weighted regression to the 3,108 counties in the contiguous United States. Global regression show food deserts exposure and density of fast-food restaurants have non-significant association with obesity and diabetes while park access has a significant inverse association with both diseases. Geographically weighted regression that takes into account spatial heterogeneity shows that, among southern states that show high prevalence of obesity and diabetes, Alabama and Mississippi stand out as having opportunity to improve park access. Results suggest food deserts exposure are positively associated with obesity and diabetes in counties close to Alabama, Georgia, and Tennessee while density of fast-food restaurants show positive association with two diseases in counties of western New York and northwestern Pennsylvania. These findings will help policymakers and public health agencies in determining which geographic areas need to be prioritized when implementing public interventions such as promoting healthy food access, limiting unhealthy food options, and increasing park access.

Financial constraints and incentives for the prevention and control of obesity in the state of Rio de Janeiro, Brazil. / Constrangimentos e incentivos financeiros para a prevenção e o controle da obesidade no estado do Rio de Janeiro, Brasil.

The present study aimed to analyze how these changes, both at the national and state levels, could affect the conditions of the implementation of obesity prevention and control (OCP) actions in primary health care (PHC) in the Rio de Janeiro State from 2014 to 2021. This study was based on policy analysis methods that emphasize the understanding of the implementation contexts, as well as the induction mechanisms and government incentives for the development of actions and integration of two projects that analyzed the OPC actions in PHC in the 92 municipalities of RJS between 2014 and 2018 (PPSUS-RJS) and between 2019 and 2021 (PEO-RJS). The results indicate that, by 2016, it was possible to observe the positive impacts of the structuring of PHC and the federal induction mechanisms in RJS. However, inflections in the expansion and funding of PHC contributed to the weakening of units, teams, and strategies, and led to retraction of resources for both state and municipal actions. Between 2016-2018, RJS's political and financial scenario deteriorated due to national crises, and the positive counterpoints since then were the induction mechanisms and federal resources that remained, in addition to the technical areas of the RJS-HD and state co-financing resources.

O estudo analisou como as inflexões político-econômicas de financiamento e de estruturação do Sistema Único de Saúde podem ter afetado as condições de implementação de ações de prevenção e controle da obesidade (PCO) na atenção primária à saúde (APS) no estado do Rio de Janeiro (ERJ) entre 2014 e 2021. Fundamentou-se em referenciais de análise de políticas, considerando contexto de implementação, antecedentes históricos, mecanismos de indução e incentivos governamentais para o desenvolvimento das ações de PCO. Baseou-se em dois projetos realizados nos 92 municípios do ERJ entre 2014 e 2018 (PPSUS-ERJ) e 2019-2021 (PEO-ERJ), pautados em análise documental, entrevistas e grupos focais com profissionais e gestores da APS. Até 2016, percebe-se os impactos positivos da estruturação da APS e dos mecanismos de indução federais. No entanto, as inflexões na expansão e no financiamento da APS contribuíram para o enfraquecimento de unidades, equipes e estratégias, além de uma retração de recursos para as ações estaduais e municipais. Entre 2016-2018, a crise política e financeira do ERJ foi potencializada pelas crises nacionais, e os contrapontos positivos desde então foram os mecanismos de indução e recursos federais que permaneceram, além das áreas técnicas da SES-ERJ e do cofinanciamento estadual.

Developing the Feast for the Future Program through a Community Visioning Process.

BACKGROUND: Three tribal communities in the Southwestern United States have a long-standing partnership with the Johns Hopkins Center for Indigenous Health (JHCIH). OBJECTIVES: In response to community concerns about obesity, three tribal communities and Johns Hopkins Center for Indigenous Health partnered to develop culturally relevant plans for a new program. METHODS: Using a "community visioning" process, a community advisory board (CAB) from each community identified opportunities, challenges, goals, and visions for their communities. The CABs consulted with experts in pediatrics, nutrition, food distribution, agricultural restoration, and community and school gardening. RESULTS: The CABs developed seven components for Feast for the Future: 1) Edible School Gardens; 2) Traditional Food-ways Education Program; 3) Community Gardens, Orchards, and Greenhouses; 4) Farmers Markets; 5) Farmers Workshops; 6) Family Gardens; and 7) a Mobile Grocery Store. CONCLUSIONS: A community-based participatory action research (CBPAR) process was critical to developing a culturally appropriate program that built on community strengths.

Obesity-Preventive Behaviors and Improvements in Depression among Diverse Utah Women Receiving Coaching from Community Health Workers.

OBJECTIVES: This study evaluated how high versus low-intensity community wellness coaching and health behaviors were associated with changes in depression screen results over one year. METHODS: This was an analysis of secondary data collected in a 12-month obesity-related community health worker (CHW) program for 485 Utah women of color. Depression screen (Patient Health Questionnaire-2 score ³3) and self-reported fruit/vegetable consumption and physical activity (FV/PA) were recorded quarterly. Associations between FV/PA and changes in depression screen over time were evaluated in multivariable models. RESULTS: Positive depression screen prevalence declined over 12 months (21.7% to 9.5%) with no difference between study arms. Overall, FV ³5 times/day (AOR=1.5; 95% CI 1.0-2.2), any PA (AOR=3.1; 95% CI 1.5-6.4), and muscle strengthening activities (AOR=1.13; 95% CI 1.01-1.26) were associated with improved depression screen results over time. CONCLUSION: These results indicate value in addressing and evaluating depression in obesity-related interventions in underserved communities.

Consequences of receiving weight-related advice from a healthcare provider: Understanding the varied experiences of people with higher weight.

Healthcare providers regularly give weight-related advice (e.g., behavioral weight loss counseling) to patients with higher weight (BMI ≥30 kg/m2). The U.S. Preventive Services Task Force recommends this practice on the basis that behavioral weight-related advice can motivate patients to attempt weight loss; however, it is also possible that this advice has adverse consequences (e.g., negative psychological reactions). In this study, we examined people's reported reactions to a recent experience of receiving weight-related advice from a healthcare provider. U.S. adults (N = 189) with higher weight who reported having received weight-related advice completed an online survey via Prolific. They answered questions about their most recent experience of receiving weight-related advice, including the purpose of the visit, characteristics of their provider, and characteristics of the advice itself. They also provided demographic information and indicated their trust in healthcare providers and the healthcare system. 90.5% of participants (n = 171) reported having one of three types of reactions to their provider's weight-related advice. Participants (1) felt motivated to change their behaviors and weight; (2) felt bad or guilty about their behaviors and weight; or (3) felt both motivated to change and bad or guilty. Using chi-square tests of independence and one-way ANOVAs, we examined how various participant characteristics and characteristics of the visit, provider, and advice itself differed across these three groups. We found significant demographic differences across the groups and found that a disproportionate amount of people in the "motivated" group reported having requested the weight-related advice and having had a two-way discussion about weight with their provider. Whereas some people feel motivated after receiving weight-related advice from a healthcare provider, others are left feeling bad about themselves or ambivalent. Understanding these varied reactions may provide insights into how healthcare providers can deliver advice that is motivating without eliciting negative psychological reactions.

Designing healthier and more sustainable ultraprocessed foods.

The food industry has been extremely successful in creating a broad range of delicious, affordable, convenient, and safe food and beverage products. However, many of these products are considered to be ultraprocessed foods (UPFs) that contain ingredients and are processed in a manner that may cause adverse health effects. This review article introduces the concept of UPFs and briefly discusses food products that fall into this category, including beverages, baked goods, snacks, confectionary, prepared meals, dressings, sauces, spreads, and processed meat and meat analogs. It then discusses correlations between consumption levels of UPFs and diet-related chronic diseases, such as obesity and diabetes. The different reasons for the proposed ability of UPFs to increase the risk of these chronic diseases are then critically assessed, including displacement of whole foods, high energy densities, missing phytochemicals, contamination with packaging chemicals, hyperpalatability, harmful additives, rapid ingestion and digestion, and toxic reaction products. Then, potential strategies to overcome the current problems with UPFs are presented, including reducing energy density, balancing nutritional profile, fortification, increasing satiety response, modulating mastication and digestion, reengineering food structure, and precision processing. The central argument is that it may be possible to reformulate and reengineer many UPFs to improve their healthiness and sustainability, although this still needs to be proved using rigorous scientific studies.

Wet-type grinder-treated okara modulates gut microbiota composition and attenuates obesity in high-fat-fed mice.

Wet-type grinder (WG) is a nanofiber technology used to atomize dietary fiber-rich materials. WG-treated okara (WGO) exhibits high dispersion and viscosity similar to those of viscous soluble dietary fibers. Here, we studied the effect of WGO supplementation on obesity and gut microbiota composition in high-fat diet (HFD)-fed mice. WGO intake suppressed body weight gain and fat accumulation, improved glucose tolerance, lowered cholesterol levels, and prevented HFD-induced decrease in muscle mass. WGO supplementation also led to cecum enlargement, lower pH, and higher butyrate production. The bacterial 16S ribosomal RNA genes (16S rDNA) were sequenced to determine the gut microbiota composition of the fecal samples. Sequencing of bacterial 16S rDNA revealed that WGO treatment increased the abundance of butyrate producer Ruminococcus and reduced the abundances of Rikenellaceae, Streptococcaceae, and Prevotellaceae, which are related to metabolic diseases. Metabolomics analysis of the plasma of WGO- and cellulose-treated mice were conducted using ultra-high-performance liquid chromatography-mass spectrometry. Metabolic pathway analysis revealed that the primary bile acid biosynthesis pathway was significantly positively regulated by WGO intake instead of cellulose. These results demonstrate that WG is useful for improving functional properties of okara to prevent metabolic syndromes, including obesity, diabetes, and dyslipidemia.

How has the COVID-19 pandemic affected the delivery of preventive healthcare? An interrupted time series analysis of adults in English primary care from 2018 to 2022.

OBJECTIVE: Offering advice and support for smoking, obesity, excess alcohol, and physical inactivity is an evidence-based component of primary care. The objective was to quantify the impact of the pandemic on the rate of advice or referral for these four risk factors. METHODS: A retrospective cohort study using primary care data from 1847 practices in England and 21,191,389 patients contributing to the Oxford Clinical Informatics Digital Hub. An interrupted time series analysis was undertaken with a single change point (March 2020). Monthly trends were modelled from 1st January 2018 - 30th June 2022 using segmented linear regression. RESULTS: There was an initial step reduction in advice and referrals for smoking, obesity, excess alcohol, and physical inactivity in March 2020. By June 2022, advice on smoking (slope change -0.02 events per hundred patient years/month (EPH/month); 95% confidence interval (CI) -0.17, 0.21), obesity (0.06 EPH/month; 95% CI 0.01, 0.12), alcohol (0.02 EPH/month; 95% CI -0.01, 0.05) and physical inactivity (0.05 EPH/month; 95% CI 0.01, 0.09) had not returned to pre-pandemic levels. Similarly, smoking cessation referral remained lower (0.01 EPH/month; 95% CI -0.01, 0.09), excess alcohol referral returned to similar levels (0.0005 EPH/month; 95% CI 0.0002, 0.0008), while referral for obesity (0.14 EPH/month; 95% CI 0.10, 0.19) and physical inactivity (0.01 EPH/month; 95% CI 0.01, 0.02) increased relative to pre-pandemic rates. CONCLUSION: Advice and support for smoking, and advice for weight, excess alcohol and physical inactivity have not returned to pre-pandemic levels. Clinicians and policy makers should prioritise preventive care in COVID-19 recovery plans.

Effectively communicating with local policymakers: a randomized trial of policy brief dissemination to address obesity.

Introduction: Evidence-based policies are a powerful tool for impacting health and addressing obesity. Effectively communicating evidence to policymakers is critical to ensure evidence is incorporated into policies. While all public health is local, limited knowledge exists regarding effective approaches for improving local policymakers' uptake of evidence-based policies. Methods: Local policymakers were randomized to view one of four versions of a policy brief (usual care, narrative, risk-framing, and narrative/risk-framing combination). They then answered a brief survey including questions about their impressions of the brief, their likelihood of using it, and how they determine legislative priorities. Results: Responses from 331 participants indicated that a majority rated local data (92%), constituent needs/opinions (92%), and cost-effectiveness data (89%) as important or very important in determining what issues they work on. The majority of respondents agreed or strongly agreed that briefs were understandable (87%), believable (77%), and held their attention (74%) with no brief version rated significantly higher than the others. Across the four types of briefs, 42% indicated they were likely to use the brief. Logistic regression models showed that those indicating that local data were important in determining what they work on were over seven times more likely to use the policy brief than those indicating that local data were less important in determining what they work on (aOR = 7.39, 95% CI = 1.86,52.57). Discussion: Among local policymakers in this study there was no dominant format or type of policy brief; all brief types were rated similarly highly. This highlights the importance of carefully crafting clear, succinct, credible, and understandable policy briefs, using different formats depending on communication objectives. Participants indicated a strong preference for receiving materials incorporating local data. To ensure maximum effect, every effort should be made to include data relevant to a policymaker's local area in policy communications.
