This guide is a starting point for parents, teachers, health professionals, law enforcement personnel, alcohol retailers, policymakers, and others who are concerned with the well-being of children. It describes three basic prevention strategies and ways they can be applied in the home, the school, and the community, and offers effective, practical strategies for communities that have decided to take action to prevent underage drinking, especially among children and young adolescents. These strategies may lead to such changes as revised zoning laws, new policies or legislation, better enforcement of existing laws, and establishment of school policies on alcohol use. To help the reader better understand how to put these strategies into action, the guide also includes real-life examples of efforts by people around the country to prevent drinking by 9- to 15-year-olds. Although the strategies may be adapted in different ways by different communities, their science base ensures that no matter what the location, from rural farming areas, to suburban school districts, to inner-city neighborhoods, these strategies work. Also included are: (1) a list of materials offered by the federal agency funding partners in this initiative, that will be useful to those who are developing prevention campaigns in their communities; and (2) A list of directories of individual State agencies or regional offices that can provide local resources. (Contains 38 endnotes.) [This document was produced by The Leadership to Keep Children Alcohol Free.]
