Advocating evidence-based health promotion: reflections and a way forward.

In the past few years, significant advances have been made in health promotion to generate readily accessible systematic reviews of evidence on the effectiveness of interventions and programs. The influence of this evidence on policy and practice has, however, been unpredictable, and proponents of evidence-based practice are identifying ways to increase the use of research in decisions about health promotion interventions. This paper examines the following questions: (i) is the evidence that is available on the effectiveness of interventions actually relevant and useful to current policy and practice contexts?; and (ii) what is the researcher's or reviewer's role in interpreting the available evidence and advocating action based on their interpretations? The paper concludes by proposing an 'evidence-agenda map' to assist advocates of evidence-based policy and practice to identify the health promotion goals they seek to influence against the required and available evidence.
