Core Outcome Measures in Effectiveness Trials

Defining core outcomes for school-based intervention studies on preventing childhood overweight and obesity

General Information

Summary:
Worldwide the prevalence of childhood overweight and obesity has increased persistently in the last decades. Therefore, prevention of overweight and obesity in children should be an international public health priority. Evidence for the effectiveness of prevention programs for childhood obesity is gradually growing. Schools are an ideal setting for intervention programmes, as they reach many children with whom there is intensive contact. However, the outcomes reported by school-based intervention studies on prevention of childhood obesity, vary greatly, reducing the comparability between studies. Hence, there is need for a set of key outcomes that should be measured in future studies on school-based interventions aimed at prevention of childhood overweight and obesity. This project will establish a core outcome set for school-based interventions aimed at prevention childhood (6-12 years) overweight and obesity by 1) conducting a systematic review into preventive school-based interventions for childhood obesity to identify different outcomes, and 2) by conducting a Delphi study among relevant stakeholders to establish consensus on a core outcome set.

Method(s)

Consensus meeting
Delphi process
Survey
Systematic review

We will create a Core Outcome Set (COS) for school-based interventions aimed at prevention of childhood overweight and obesity. Firstly we will conduct a systematic review into preventive school-based interventions for childhood obesity to identify different outcomes. Secondly we will conduct a two-step Delphi procedure to establish consensus on the previously produced list of outcomes for the evaluation of school-based intervention studies on prevention of childhood overweight and obesity. International stakeholders (researchers, policy makers, health professionals, and children and their parents) will be approached to establish a selection of outcomes using an online Delphi survey and to obtain consensus on outcomes by a consensus meeting.
