The Youth Risk Behavior Survey (YRBS) is a national survey developed by the Division of Adolescent and School Health, Centers for Disease Control and Prevention (CDC), in collaboration with 71 state and local departments of education and 19 federal agencies. The YRBS specifically investigates behaviors related to the leading causes of mortality, morbidity; and social problems. This YRBS report concentrates on high school and middle school students in Alaska. It examines student responses about six categories of adolescent behavior: (1) behaviors that result in unintentional and intentional injuries; (2) tobacco use; (3) alcohol and other drug use; (4) sexual behaviors that can result in HIV infection, other sexually transmitted diseases (STDs), and unintended pregnancies; (5) dietary behaviors; and (6) physical activity. Numerous tables highlight findings throughout the text. Appendix A contains high school questions and Alaska responses, and Appendix B contains middle school questions and Alaska responses. (DR)
