The 10-volume "Health Facts" series is intended to supplement health education curricula and provide a handy reference for individuals who would like additional background information on particular health topics. The emphasis is placed on topics and examples relevant to youth of middle and high school age. The five sections in this book provide teachers with basic facts about the public health approach to injury prevention. The book includes information about those most at risk of injury; the costs of injury; the role alcohol and other drugs play in injuries; unintentional injuries, which have traditionally been called "accidents"; and intentional injuries due to violence and suicide. An easy to read reference format offers clear, concise data intended to familiarize educators with the most important facts about the issues and concerns. A glossary, a list of resources, and 22 references complete the volume. (LL)
