This report presents data on the current status of adolescent health. Many of the measures of health status are shown by single year of age or by 2- or 3-year age intervals to highlight the changes that occur in health status as adolescents move through this important developmental period. Summary measures combining 5- or 10-year age groups (the standard for analyses of childhood health events) do not adequately capture the wide variation in health status and the vast developmental differences between younger and older adolescents. This report is divided into sections on population characteristics, health status, violence and victimization, reproductive health, risk behaviors, and health care access and utilization. (Contains 40 figures. Individual sections contains references.)
