title: Health of adolescents and young adults: trends in achieving the 21 Critical National Health Objectives by 2010.
abstract: OBJECTIVE
  The 21 Critical National Health Objectives (CNHOs) for Adolescents and Young Adults derived from Healthy People 2010 addressed the most significant threats to the health of individuals aged 10-24 years. This study assessed trends in the 21 CNHOs between 1991 and 2009, and from baseline years for which 2010 targets were established to 2009, and the extent to which targets were achieved.
  
  
  METHODS
  For one CNHO (new HIV diagnoses), national data were not available. For CNHOs measured by census systems, the percentage of change in each health outcome was calculated between 1991 and 2009 and between baseline years and 2009. Any change ≥5% was considered as an improvement or deterioration. For CNHOs measured by national probability-based surveillance surveys, multivariate logistic regression was conducted using Stata Version 10.0 (StataCorp, College Station, TX) to calculate odds ratios for each outcome from 1991, and from baseline years to 2009, controlling for gender, race/ethnicity, and age or school grade-level. To calculate the percentage of targets being achieved, the difference between baseline data and 2009 data was divided by that between baseline data and target.
  
  
  RESULTS
  Adolescents and young adults achieved two targets (rode with a driver who had drunk alcohol, physical fighting), improved for 12 CNHOs, made mixed progress by sub-objective for two, showed no progress in four, and regressed in achieving two (Chlamydia infections; overweight). Progress varied by demographic variables.
  
  
  CONCLUSIONS
  Although encouraging trends were seen in young people's health, the United States achieved only two CNHOs. Attention is needed to improve the health and reduce disparities among young people.
