Day Two – Wednesday 26th June

Strand – Health & Well Being

Session Five: 11.15am – 12.45pm

Excess alcohol consumption has serious adverse effects on health and violence-related harm. The 2009, UK General Lifestyle Survey reported that approximately 37% of men and 29% of women drink to excess and so the potential population health impact from a reduction in consumption is considerable.

Measuring consumption is difficult but is likely to be closely associated with alcohol availability.  This study is a natural experiment of the effect of change in outlet density between 2005-2011, in Wales, UK on the rate of alcohol-related adverse outcomes in the population of 2.4million people aged 16 years and over. Data on outlets are held by the 22 local authorities under The Licensing Act 2003 and we will calculate the density of outlets within the vicinity of each person’s place of residence in each year.

The outcome measures we will use are changes in: alcohol consumption using annual Welsh Health Survey data, alcohol-related hospital admissions, Accident & Emergency department attendances between midnight-6am, and alcohol-related violent crimes against the person. Data have been anonymously record-linked within the Secure Anonymised Information Linkage Databank at individual and 2001 Census Lower Super Output Area levels. We will conduct multilevel statistical and spatial analyses to assess associations between change outlet density and changes in each outcome measure. We will assess the impact on health inequalities from differential changes in outlet density, adjusted for population migration.
