1. Centre for Diet and Activity Research Social inequalities in physical activity: do environmental and policy interventions help reduce the gap? A pilot systematic review David Humphreys 1 & David Ogilvie 1,2 1 CEDAR, Institute of Public Health, University of Cambridge 2 MRC Epidemiology Unit, Cambridge CEDAR-ISAG scientific meeting, 24 th January 2012

2. Centre for Diet and Activity Research Background Opportunities to physically active may be limited by social position or group membership. There is limited evidence about the social distribution of effectiveness within interventions to improve physical activity. Such information is required as we implement more universal interventions.

3. Centre for Diet and Activity Research Research Aims Aims of this pilot: a)To assess the availability of information on the social distribution of: intervention effects targeting or allocation of interventions baseline information on participants b) To determine whether sufficient information is available for a full evidence synthesis

4. Centre for Diet and Activity Research Method Stages: 1)Review of reviews 2)Review of primary studies Search strategy: Active Living Research reference lists 2002-2010 http://activelivingresearch.org/resourcesearch/referencelist

13. Summary & Future Directions Assessing existing research through an “equity lens” Current systematic reviews lack information There may be information from existing primary studies to synthesise distributional effects Future directions: Finish coding primary studies Pilot synthesis Development of a full systematic review
