The 1992 National Health Interview Survey-Youth Risk Behavior Survey (NHIS-YRBS) studied 13,789 youth 12-21 years of age. This report presents the data according to sex, age, Hispanic origin, and race for youth of non-Hispanic origin. The 10 data tables cover: cigarette and other tobacco use, alcohol and other drug use, sexual experience, HIV/AIDS education, runaway and homeless experiences, violence, unintentional injury control, weight control, and participation in physical activities. Analysis of the data revealed that a substantial number of U.S. youth are engaging in risk-taking behaviors that can lead to chronic disease, injury, and death. A significant proportion had smoked cigarettes (59.9 percent), drunk alcohol (67.7 percent), and used illegal drugs (31 percent). Over 60 percent of all never-married youth 14-21 years of age had engaged in sexual intercourse at least once in their lifetime; 43.9 percent had had more than one sex partner. Nearly one-half of males (48.1 percent) and 29.4 percent of females had been in a physical fight in the previous year, and nearly 1 in 4 male youth (23.8 percent) had carried a weapon in the previous month. The survey data suggest opportunities to enhance the health of youth through early intervention on the part of parents, schools, and communities. Appendices include technical notes on the survey methodology and definition of terms used in the report. (Contains 51 references.) (ND)
