Across the world an average of 565 young people aged 10 to 29 die every day through interpersonal violence, with males at greater risk, and for each death there are an estimated 20 to 40 youth that require hospital treatment for a violence-related injury (1). The impact of youth violence reaches all sectors of society, placing huge strains on public services and damaging communities. Reducing harmful alcohol use and violence among young people should thus be considered a priority for policy makers and practitioners across a broad range of agencies, with public health professionals having a key role in leading partnerships and prevention. This fact sheet summarizes the role of alcohol in youth violence, the magnitude of the problem, risk factors for involvement in alcohol-related youth violence, prevention measures and the role of public health.
