Obesity prevention policy interventions: Prevention Strategies & Guidelines

To reverse the obesity epidemic, places and practices need to support healthy eating and active living in many settings. Once a logic model has been created, practitioners can use it as a guide to developing evaluation questions and an evaluation plan.

Environment obesity prevention Planning C: Politics and Space. As explained above B1 and B2the long duration of policy processes reduced the likelihood of policy adoption. The analysis of the policy process for each policy intervention involved a deductive thematic analytical approach underpinned by multiple political science theories. Interviewees indicated that this created a barrier to policy adoption due to the relatively short-term 4 year political cycles in Victoria, especially considering that there were changes in the governing political party over the course of the policy study period. There was strong evidence from interviews for this effect across the HTV policy process investigations, with examples of internal government staff members facilitating network coordination and negotiation processes with stakeholders to reduce resistance to policy options. State-by-State Reach of Child Nutrition Policies Several federal policies aim to make healthy foods accessible and affordable to children and adults nationwide, and states play a big role in how these policies are implemented.

  • Unit interventionss for the included diseases were provided to us by the Australian Institute of Health and Welfare for a previous obesity prevention policy interventions [ 16 ] and were inflated from values to values to estimate the healthcare costs-savings resulting from the intervention. In addition, changes to institutional culture to one that supports innovation regarding preventive health is likely to be beneficial in securing adopting of recommended obesity prevention policies [ 68 ].

I. Background and Objectives for the Systematic Review

Consequently, this study highlighted the need to improve obesity prevention policy interventions skills of policy makers in effective negotiation and consensus building in order to facilitate timely progression of obesity prevention policy solutions. Estimates for indicate approximately AUD3. View Article Google Scholar 9. Preventing Childhood Obesity: Health in the Balance.

We will abstract detailed information about what obesity measures, obesity-related behavioral outcomes, and other non-health related outcomes are reported in integventions papers. We will explore the availability and usefulness of additional sources that have articles on the built environment and transportation.

When Sadeghi et al. The analysis of the processes leading to the adoption of each policy intervention revealed numerous interconnected influences on obesity prevention policy processes [ 484951 ]. Future research investigating intervention characteristics that facilitate the durability of effects is also required. Although policy makers, advocates and previous policy studies agree on the importance of evidence in obesity prevention policy, the focus of such discussion has largely been on evidence of the policy problem and effectiveness of policy solutions [ 1897]. When policy actors employed various strategic skills, a number of virtuous system effects were stimulated, such as the development of viable policy solutions that aligned with decision-maker beliefs and government objectives, as well as improved implementation feasibility and stakeholder support. While systems thinking and CLDs have been utilised extensively to understand the causes and complex interdependencies driving obesity prevalence [ 3435 ], and to inform and evaluate obesity prevention initiatives [ 2936 ], the application to policymaking within the obesity prevention context is scarce [ 37 ].

Background

The meta-CLD contained 12 influential feedback loops that provide insight into the complex obesity prevention policy interventions of policy decision-making interfentions the context of HTV. References 1. The presentation of viable and feasible policy solutions was described by participants as important in increasing support for policy interventions from decision-makers, leading to increased obesity prevention policy adoption.

Policies interact with other existing and emerging policies to affect outcomes; activities and outputs also may be designed to address the requirements of multiple policies. The framework has limitations. For more information about this message, please visit this page: About CDC. The EPC will complete a disposition of all peer review comments. For example, in implementing new state-level farm-to-school policy, the Department of Education may reallocate resources and draft new rules governing how the policy will be implemented across school districts. What population-based data sources have been used in studies of how programs, policies or built environment changes affect or are associated with obesity prevention and control outcomes?

Models for Communities

Policies may also need to be modified. The same process will be used for all data abstraction activities throughout this review project. This approach is difficult to apply to policy interventions because they involve a continual and often cyclical interplay among inputs, activities, and outputs and because the path to successful outcomes is neither linear nor constant 11,13,

Families consignment in low-income or subsidized housing participated in a randomized lottery to receive a voucher that enabled them to move to a higher income neighborhood. Changes can occur in the following types of environments 18 :. The goal of this project is not to analyze or prioritize the gaps identified by the TEP. For each U.

Evaluation of farm-to-school implementation might address whether locally grown foods were delivered to schools and served in cafeterias as intended; cafeteria staff, parent, and student response ie, acceptability ; and the effects on the cost of school lunches ie, affordability. The framework is organized according to the 4 standard sections of a logic model: inputs, activities, outputs, and outcomes Changes will not be incorporated into the protocol. Funding from the Centers for Disease Control and Prevention CDC and others is spurring the emergence of promising obesity prevention initiatives, presenting a distinct opportunity to build the body of practice-based evidence. Findings can, for example, help to distinguish whether disappointing outcomes are due to problems with the policy or with its implementation. Division of Nutrition, Physical Activity, and Obesity.

Dashed lines indicate where there was some data to demonstrate an association between factors, however triangulation across data sources or methods could not be achieved. All of the selected policy interventions were adopted in Victoria over the period —, although some policies, such as Menu Kilojoule Labelling Legislation required multiple formal iterations of policy proposals prior to policy adoption, and some aspects of the Land Use Planning Policies e. Effects of a community-oriented obesity prevention programme on indicators of body fatness in preschool and primary school children.

A third category of community-based interventions targets changes in the places where people live, learn, work, and play. As with education in integventions, the sooner we act, the better. The policy interventions selected for inclusion were derived from the broader suite of policies considered for adoption as part of HTV, with selection based on key characteristics of each intervention to ensure heterogeneity e. Train food service staff in healthy food preparation techniques and food safety 379. Food Policy. Although there is evidence to support the beneficial effects of increased PA and diet as a basic and early strategy at any time and for any age against obesity [ 1415 ], no summarized study is available to critically evaluate the effectiveness of different policies with different interventional approaches in prevention of childhood obesity considering the role of setting, age, geographical distribution, and intervention type or strategy.

To determine the categories of variables related to obesity and co-outcomes in each data system, we will take the following approach:. The final obesity prevention does not necessarily represent the views of individual reviewers. We recognize imterventions defining the behavioral outcomes of physical activity and dietary change will be challenging because many self-reported instruments have been developed and reported in the literature, 18 with varying degrees of comprehensiveness, validity and reliability. Evaluation of farm-to-school implementation might address whether locally grown foods were delivered to schools and served in cafeterias as intended; cafeteria staff, parent, and student response ie, acceptability ; and the effects on the cost of school lunches ie, affordability.

We will describe the data sources by criteria for population-based data systems, whether obesity prevention policy interventions data source is in the NCCOR registry, and what country, state or community it is from. The summary report will include various data system attributes across the entire list of data systems. For each U. Despite the need for policy action to create healthier environments, little is known about policy approaches that are most effective 2,4,7. Evaluation of farm-to-school implementation might address whether locally grown foods were delivered to schools and served in cafeterias as intended; cafeteria staff, parent, and student response ie, acceptability ; and the effects on the cost of school lunches ie, affordability. The list includes sections related to formative, process, and outcomes evaluation.

Introduction The prevalence of overweight and obesity continues to increase internationally with significant obesity prevention policy interventions impacts on morbidity and mortality [ 1 ]. There are many systematic reviews or meta-analysis studies that have been performed in specific settings such as schools only [ 121360 ] or were performed for single-axis interventions such as physical activity only [ 1061 ], diet only [ 13 ] or with limited duration of intervention [ 62 ] or follow-up [ 6364 ] and different age ranges [ 9106064 ]. Canberra: ABS,

For example, incorporating local foods into unhealthy recipes obesity prevention policy interventions a potential unintended consequence of farm-to-school policies. Figure 2. Practitioners cannot anticipate all possible consequences and, therefore, should assess both positive and negative unintended outcomes For example, a state may enact enabling legislation in support of complete streets. We will maintain a list of these excluded articles that used non-validated instruments for diet and physical activity assessments. Email Address.

Offer children physical activity obesity prevention policy interventions before and after school, including competitive sports and noncompetitive activities 123789. Priority-setting decisions are likely to require comparative evidence on the cost-effectiveness of a suite of policy-relevant interventions that have been evaluated using consistent methods [ 13 ]. The list of potential interventions was reviewed annually to ensure all relevant interventions based on emerging evidence and global policy activity were considered for inclusion. This priority-setting study can be used to guide this strategy. Key informant interviews were conducted between December and April

Types of environments: Physical Economic Social Communication. This may result in incomplete coding for a number of data systems. Therefore study questions, design, and methodological approaches do not necessarily represent the views of individual technical and content experts.

The logic pathways were used to model the intervention costs and the impact of the intervention on one or both risk factors. By better understanding stakeholder motives for their disagreement with proposals, policy entrepreneurs are likely to be better equipped to develop strategies that can reduce resistance to change [ 81 ]. American Journal of Public Health. Public Management Review. These balancing loops including an organisational norm of risk aversion, and the complexities resulting from a whole-of-government policy approach and in-depth stakeholder consultation. The duration of intervention effect varied for program-based interventions according to the characteristics of each intervention.

To determine the categories of variables related to obesity and co-outcomes in each data system, we will take the following approach:. Policy : is broadly defined to include both formal public policies at local, state and federal levels of government, and organizational level policies, such as those implemented by large organizations, worksites or school districts. We will describe types of study designs and analytic methods being used, their frequency of use, and whether they are preferred for certain policies, policies or data sources. On This Page. For example, municipalities may have restrictions on foods served in school cafeterias; policies may need to be modified to allow schools to serve foods grown in school gardens. Inputs related to solutions include content experts, evidence-based approaches, existing state policies, and model policies such as exemplar farm-to-school policies enacted in other states.

Government policy makers and external policy actors that were able to frame policy narratives to align policy proposals to decision-maker beliefs R1 played an important role in reinforcing policy change. Schools can also promote health outside of the classroom, by surrounding students with opportunities to eat healthy and stay active. A search of electronic data bases retrieved 30, records.

Obesity prevention: a proposed framework for translating evidence into action. The ACE-Obesity Policy model A proportional, multi-state life table Markov cohort model was developed to quantify the relationship between characteristics of the population, risk factor prevalence and obesity related diseases to estimate the longer-term outcomes of obesity prevention initiatives. Oxford: Westview press; A simplified meta-CLD was generated from synthesis of common elements across each of the six policy interventions. Schools can also promote health outside of the classroom, by surrounding students with opportunities to eat healthy and stay active. Case study research: design and methods.

For example, not all data systems provide enough details about their data specifications and thus may lead to missing information.

Public health practitioners can work for years to raise awareness of a public health problem and potential solutions and, following enactment of new policy, can work still obrsity to assist with its full implementation. Policies also should be cost-effective; in other words, they should use resources in ways that contribute to improvements that are equal to or greater than alternative policies or programs. The U. Well-executed experimental studies provide unbiased estimates of the effect of the intervention on the outcome because the intervention assignment is under the control of the investigator and randomly assigned to some study participants and withheld from others. Solid lines depict components that apply to the current state of policy. See Appendix A for definitions of terms.

Strategies for the prevention policy interventions control of obesity in the school setting: systematic review and meta-analysis. Interventions targeted at children were modelled under the assumption that the BMI change resulting from the intervention was maintained over the lifetime of the affected population. The identification of balancing feedback dynamics that contribute to policy resistance helped to highlight characteristics of organisational and policy systems that can be altered to better support obesity prevention policy change. Regulatory interventions tended to rank higher on their cost-effectiveness results, driven by lower implementation costs. Thinking in systems: a primer. CMAJ Open.
