title: What gets measured gets done: assessing data availability for adolescent populations.
abstract: OBJECTIVE
  To identify specific adolescent sub-populations; to evaluate the health data available regarding these populations related to 21 key national adolescent health objectives from Healthy People 2010; and to make recommendations for improving data capacity to further efforts to reduce health disparities among adolescents.
  
  
  METHODS
  Adolescent populations were identified through a consensus process. Academic and government literature was extensively reviewed using internet search techniques to identify available national data for each of these populations on each key national health objective.
  
  
  RESULTS
  18 adolescent subpopulations were identified. These populations fit into four overlapping categories defined by demography, legal status, chronic health condition, or other special characteristics. Overall, national, population-based data regarding these sub-populations were located for 36% of the 21 health objectives. Within the sub-populations, most data was available for ethnic/racial groups, with 57-81% of each of the objectives having data. Data regarding rural/urban groups were found for about one-half of the 21 objectives, and data were located on all other groups for one-fourth or fewer of the objectives. Within the objectives, substance abuse objectives were the most widely measured, with data available for 56-78% of the various populations. For some objectives, such as drug-or alcohol-related motor vehicle deaths depression among the developmentally disabled, no national data were found.
  
  
  CONCLUSIONS
  There are still too little data available regarding the specific health status or health objectives for different adolescent populations. A national adolescent data-priority agenda is needed to develop strategies to improve health data regarding adolescent sub-populations. Federal and state health monitoring agencies could create national health profiles of different populations, include more population markers in health studies, and develop tools for population-specific health assessment, particularly for those within the government's care, including incarcerated and foster care youth.
