The 1999 Wisconsin Youth Risk Behavior Survey (YRBS) was conducted as part of a national survey effort by the U.S. Centers for Disease Control and Prevention. A stratified random sample of classrooms in all public schools with ninth through twelfth grades was taken. The YRBS was administered to 1,336 students in 46 public schools in Wisconsin in the spring of 1999. The students who participated in the survey are representative of students in Wisconsin. The results of this survey can be used to make important references concerning the health-risk behavior of all Wisconsin public high school students in grades 9 through 12. The following issues were examined in the survey: assets, unintentional injuries, weapons and violence, suicide, tobacco, alcohol and other drugs, sexual behavior, diet and exercise, and relationships between risk factors. A questionnaire is provided. (Contains 2 tables, 50 figures, and 30 references.) (MKA)
