A portrait of multiple risk-taking among teens. Using recent data from the National Longitudinal Study of Adolescent Health (Add Health) and the 1995 National Survey of Adolescent Males (NSAM), we describe the degree to which teens engage in multiple health risk behaviors and contrast it with the extent to which teens participate in positive behaviors such as spending time with parents and being involved in extra-curricular activities. Describing participation in these behaviors is an important part of understanding teens' exposure to health risks and monitoring efforts to reduce those risks.
