  1. Social inequalities in physical activity: do environmental and policy interventions help reduce the gap? A pilot systematic review David Humphreys1 & David Ogilvie1,2 1 CEDAR, Institute of Public Health, University of Cambridge 2 MRC Epidemiology Unit, Cambridge CEDAR-ISAG scientific meeting, 24th January 2012

  2. 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. 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. Method Stages: • Review of reviews • Review of primary studies Search strategy: • Active Living Research reference lists 2002-2010 http://activelivingresearch.org/resourcesearch/referencelist

  5. Inclusion Criteria • Types of study: • Stage 1: Systematic reviews or meta-analyses • Stage 2: Primary intervention studies • Type of intervention: Environmental & Policy • Type of outcome: Change in physical activity

  6. Coding Matrix • Social inequalities - “PROGRESS-Plus” framework – Cochrane/ Campbell Equity Methods Group (e.g.)

  7. Stage 1: Review of Reviews Study search: Active Living Research reference lists 2446 primary studies excluded 2586 abstracts scanned 4 reviews not found in ALR included 140 reviews collected for full text screening 125 reviews excluded 19 reviews obtained and coded

  8. Stage 1: Results

  9. Stage 2: Review of Primary Studies Pooled 203 non-duplicated studies from systematic reviews 92 studies currently unavailable 111 studies collected 50 studies coded to date 20 studies excluded 30 studies analysed

  10. Stage 2: Results

  11. 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
