A new approach to assessing the health benefit from obesity interventions in children and adolescents: The assessing cost-effectiveness in obesity project

Objective:To report on a new modelling approach developed for the assessing cost-effectiveness in obesity (ACE-Obesity) project and the likely population health benefit and strength of evidence for 13 potential obesity prevention interventions in children and adolescents in Australia.Methods:We used the best available evidence, including evidence from non-traditional epidemiological study designs, to determine the health benefits as body mass index (BMI) units saved and disability-adjusted life years (DALYs) saved. We developed new methods to model the impact of behaviours on BMI post-intervention where this was not measured and the impacts on DALYs over the childs lifetime (on the assumption that changes in BMI were maintained into adulthood). A working group of stakeholders provided input into decisions on the selection of interventions, the assumptions for modelling and the strength of the evidence.Results:The likely health benefit varied considerably, as did the strength of the evidence from which that health benefit was calculated. The greatest health benefit is likely to be achieved by the ‘Reduction of TV advertising of high fat and/or high sugar foods and drinks to children’, ‘Laparoscopic adjustable gastric banding’ and the ‘multi-faceted school-based programme with an active physical education component’ interventions.Conclusions:The use of consistent methods and common health outcome measures enables valid comparison of the potential impact of interventions, but comparisons must take into account the strength of the evidence used. Other considerations, including cost-effectiveness and acceptability to stakeholders, will be presented in future ACE-Obesity papers. Information gaps identified include the need for new and more effective initiatives for the prevention of overweight and obesity and for better evaluations of public health interventions.

Measuring the impact of intimate partner violence on the health of women in Victoria, Australia

OBJECTIVE Using burden of disease methodology, estimate the health risks of intimate partner violence (IPV) among women in Victoria, Australia. METHODS We calculated population attributable fractions (from survey data on the prevalence of IPV and the relative risks of associated health problems in Australia) and determined health outcomes by applying them to disability-adjusted life year estimates for the relevant disease and injury categories for Victoria, Australia for 2001. FINDINGS For women of all ages IPV accounted for 2.9% (95% uncertainty interval 2.4-3.4%) of the total disease and injury burden. Among women 18-44 years of age, IPV was associated with 7.9% (95% uncertainty interval 6.4-9.5%) of the overall disease burden and was a larger risk to health than risk factors traditionally included in burden of disease studies, such as raised blood pressure, tobacco use and increased body weight. Poor mental health contributed 73% and substance abuse 22% to the disease burden attributed to IPV. CONCLUSION Our findings suggest that IPV constitutes a significant risk to womens health. Mental health policy-makers and health workers treating common mental health problems need to be aware that IPV is an important risk factor. Future research should concentrate on evaluating effective interventions to prevent women being exposed to violence, and identifying the most appropriate mental health care for victims to reduce short- and long-term disability.

Priority setting in health: Origins, description and application of the Australian Assessing Cost–Effectiveness initiative

This article reports on the ‘Assessing Cost–Effectiveness’ (ACE) initiative in priority setting from Australia. It commences with why priority setting is topical and notes that a wide variety of approaches are available. In assessing these various approaches, it is argued that a useful first step is to consider what constitutes an ‘ideal’ approach to priority setting. A checklist to guide priority setting is presented based on guidance from economic theory, ethics and social justice, lessons from empirical experience and the needs of decision-makers. The checklist is seen as an important contribution because it is the first time that criteria from such a broad range of considerations have been brought together to develop a framework for priority setting that endeavors to be both realistic and theoretically sound. The checklist will then be applied to a selection of existing approaches in order to illustrate their deficiencies and to provide the platform for explaining the unique features of the ACE approach. A case study (ACE-Cancer) will then be presented and assessed against the checklist, including reaction from stakeholders in the cancer field. The article concludes with an overview of the full body of ACE research completed to date, together with some reflections on the ACE experience.

The cost-effectiveness of removing television advertising of high-fat and/or high-sugar food and beverages to Australian children

Objective:To model the health benefits and cost-effectiveness of banning television (TV) advertisements in Australia for energy-dense, nutrient-poor food and beverages during childrens peak viewing times.Methods:Benefits were modelled as changes in body mass index (BMI) and disability-adjusted life years (DALYs) saved. Intervention costs (AUD

) were compared with future health-care cost offsets from reduced prevalence of obesity-related health conditions. Changes in BMI were assumed to be maintained through to adulthood. The comparator was current practice, the reference year was 2001, and the discount rate for costs and benefits was 3%. The impact of the withdrawal of non-core food and beverage advertisements on childrens actual food consumption was drawn from the best available evidence (a randomized controlled trial of advertisement exposure and food consumption). Supporting evidence was found in ecological relationships between TV advertising and childhood obesity, and from the effects of marketing bans on other products. A Working Group of stakeholders provided input into decisions surrounding the modelling assumptions and second-stage filters of ‘strength of evidence’, ‘equity’, ‘acceptability to stakeholders’, ‘feasibility of implementation’, ‘sustainability’ and ‘side-effects’.Results:The intervention had a gross incremental cost-effectiveness ratio of AUD
