An aspect of alcohol harm that is under-researched is that of harm to people other than the drinker. In contrast, research on passive smoking has been of significant importance in developing tobacco control policies. This study will provide new knowledge about harm that is largely invisible or neglected, provide a more complete picture of the burden of alcohol harm in communities to inform decision-making about policy on alcohol control and contribute to international efforts to reduce alcohol consumption. It will take advantage of the Statistics New Zealand Integrated Data Infrastructure, allowing for data linkage across individuals and between datasets, to determine the contribution of alcohol to key areas of alcohol’s harm to others –FASD, traffic crash and assaults (including partner violence) separately for Maori and non-Maori. It will also provide estimates of Years of Life Lost and Disability Adjusted Years of Life.
