The EPPI-Centre carried out a scoping review to provide an overview of the current international research literature that evaluates the effectiveness of incentives to address health behaviours related to smoking, healthy eating, physical activity, obesity and weight management. This systematic review was published by EPPI-Centre in 2010. .Systematic reviews aim to find as much as possible of the research relevant to the particular research questions, and use explicit methods to identify what can reliably be said on the basis of these studies.
