4 1. To explore the wider evidence base for improving the public health and reducing inequalities in health; 2. To collate and synthesise the evidence base (improving public health and reducing inequalities in health); and 3. Engage with policy/practitioner/and academic users.

5 Systematic reviews: Housing and regeneration Housing improvement and health (Thomson et al; BMJ 2001). Are national area-based initiatives a public health investment? A systematic review (Hilary Thomson & Rowland Atkinson; est Jan 2005) Using systematic review methodology, we have examined the national evaluations of UK regeneration programmes (1980- 2004) to assess how the effectiveness of two decades of regeneration investment has been evaluated

6 Transport Health impacts of new road building (Egan et al., Am J Public Health 2003) “Systematic review of reviews” of transport policies (Morrison, J Epidemiol Comm Health 2003) Promoting walking and cycling as an alternative to using cars (“modal shift”) (Ogilvie et al., Br Med J 2004)

7 Employment The health and employment impacts of state- subsidies (Egan et al., submitted) The health impacts of workplace re-organisation: a systematic review (Egan, Bambra et al., Jan 2005) How effective are labour market interventions in helping disabled people gain employment? (Bambra, Whitehead; In press, Soc Sci Med) The epidemiology of sickness absence: a systematic review. (Bambra, Whitehead, In press)

8 Childhood disadvantage: Systematic Reviews Social consequences of poor health in childhood (Milton, Whitehead) Childhood disadvantage & health inequalities (Raine & Graham, In press: Child). Other Young women & contraceptive use: SR of research on uptake, choice, & discontinuation among adolescent girls (Williamson, et al., ongoing) Teenage mothers & smoking: systematic review of qualitative research (McDermott, Graham; Journal of Youth Studies Vol. 8 (1))

9 Increasing utility A systematic review is not the end product (or even the most useful product)...Because research evidence on its own is often not very useful to users

10 Housing systematic review Joint academic/ practitioner report incorporating Scottish Housing Law etc Evaluation by practitioners of its use and utility Report, incorporating wider range of evidence on damp, noise, asthma WHO briefing paper Academic paper (evaluations of interventions)

11 New roads review Academic paper (evaluations of health and social impacts of new roads) Summary report aimed at “Transport community” (experts and users) Input into public inquiry into the M74 extension

12 Problems with public health evidence… Problems with “high concept” notions of evidence preferred by academics “In policy circles a mixed economy of evidence prevails, with different types of scientific and non- scientific evidence used” Research that is explanatory, rather than evaluative Evidence that lacks an equity dimension Little information on costs

13 Evidence with an equity dimension: Systematic reviews assessing “differential effectiveness” of interventions Do the effects vary by social class, gender, education, ethnicity, etc? Pilot study of differential effects of community level smoking cessation/prevention interventions Based on existing Cochrane reviews

14 DH-funded project, collaboration between CRD & MRC SPHSU & University of Liverpool, Glasgow Systematic reviews CDSRDAREetc Primary studies Unpublished analyses New analyses Evidence on smoking & inequalities

15 Methodological “challenges” Post hoc analysis of primary studies Sub group analyses underpowered Within study (direct) comparisons between social groups are probably rare Between study (indirect) comparisons are possible but biased “Primary” versus “secondary” outcomes Cochrane/Campbell Equity Methods group

16 No bricks without straw... Little recent history in the UK of outcome evaluation of social interventions... Need to carry out new primary research

17 Scotland-wide, prospective, controlled study of housing renewal (Intervention=300; Control=300) Two-year follow up (postal, then face to face) Qualitative interviews...To finish 2006 1. SHARP: Scotland’s Housing and Regeneration Project

18 (Cummins S, Higgins C Petticrew, M Sparks L, Findlay A) 2. The Springburn Supermarket study* *Funded through the DH Health Inequalities Initiative S

19 3. Study of the health impacts of Edinburgh’s Congestion Charging scheme
