Lay summary
Using unique data from the International Alcohol Control (IAC) study this research will develop two new International Alcohol Control Policy Indices, one for youth and one for adults, comparable across high and middle income countries. This will, for the first time, include both policy input (legislation and regulations) and policy impact (measures of the environment impacted by the policies) for a range of key alcohol policies. The relationship between the International Alcohol Control Policy Indices and drinking patterns will be analysed to assess impact of policy in disparate high and middle income countries, among adults and young people. This study will provide new knowledge about the relationships between alcohol policy and alcohol consumption and by deriving quantifiable metrics provide a tool for communicating with public and policy makers.
