title: State requirements and recommendations for school-based screenings for body mass index or body composition, 2010.
abstract: BACKGROUND
  We present a comprehensive picture of state requirements and recommendations for body mass index (BMI) and body composition screening of children and explore the association between pediatric obesity prevalence and state screening policies.
  
  
  METHODS
  Researchers completed telephone interviews with contacts at the departments of education for all 50 states and reviewed state content standards for physical education.
  
  
  RESULTS
  Twenty states (40%) require BMI or body composition screening, and 9 states (18%) recommend BMI screening or a formal fitness assessment that includes a body composition component. The prevalence of adolescent obesity was higher in states that require BMI screening or fitness assessments with body composition than in states without requirements (16.7% vs 13.6%, P = .001).
  
  
  CONCLUSIONS
  Future studies should evaluate the effect and cost-effectiveness of BMI and body composition screening on child obesity.
