Abstract
BackgroundChildhood obesity is a major global public health problem, with governments increasingly having to undertake various strategies to reduce excess weight in their populations. Considering the increasing number of well-conducted intervention studies in the field of childhood obesity prevention, there are relatively few published economic evaluations. The proposed systematic review will explore the methods of these economic evaluations, examine the limitations and establish the evidence base for cost-effectiveness analyses.Methods/designSystematic review methodology will be applied to identify, select and extract data from published economic evaluation studies (trial-based, non-trial based, simulation-based, decision model and trial based model economic evaluations) of obesity prevention and/or treatment interventions in children and adolescents. A systematic literature search will be conducted using bibliographic databases (MEDLINE, EMBASE, CINAHL, Web of Science, EconLit, PsycINFO, Cochrane Library, Centre for Reviews and Dissemination (CRD) and Cost-Effectiveness Analysis (CEA) Registry). The review will only include full economic evaluations. There will be no restrictions based on language, perspective, follow-up duration, sample size, country or setting. To minimise selection bias, translation of non-English language articles will be undertaken. The quality of included studies will be assessed. Following data extraction, a narrative synthesis of the results from the included studies will be undertaken. Subgroup analysis will be considered where deemed appropriate.DiscussionThe findings from this review, which will include primary studies, will provide evidence to assist health policy decision makers interpret economic evaluations in this field. In addition, we will identify gaps in the current literature to inform future-related research.Systematic review registrationProspero CRD42017062236
Highlights
Childhood obesity is a major global public health problem, with governments increasingly having to undertake various strategies to reduce excess weight in their populations
Seven recent reviews [5, 19,20,21,22,23,24] have summarised the cost-effectiveness of obesity prevention and/or treatment interventions in young people; none have used or reported rigorous methods for conducting their reviews
The aim of this review is to critique the methods used in economic evaluations of child and adolescent obesity and summarise cost-effectiveness evaluations of prevention and treatment interventions
Summary
Childhood obesity is a major global public health problem, with governments increasingly having to undertake various strategies to reduce excess weight in their populations. Considering the increasing number of well-conducted intervention studies in the field of childhood obesity prevention, there are relatively few published economic evaluations. Childhood obesity is a major global public health problem, which leads to health, social and emotional problems, as well as associated high health care costs [1]. Over the last 3 decades, the percentage of people who are overweight or obese has been increasing globally [3]. Obesity is as much an issue in developing as in developed countries. The prevalence of childhood obesity may be higher in developed countries, the rate of increase over the last decade is steeper in many developing countries [4]
