title: Test of an educational intervention for osteoporosis prevention with U.S. adolescents.
abstract: OBJECTIVE
  To test the effects of an osteoporosis prevention program given to high school students
  
  
  METHODS
  Randomized, multi-site field study.
  
  
  METHODS
  The final sample for analysis was composed of 693 teens from 18 schools.
  
  
  RESULTS
  The average knowledge difference score of the OPTIONS group was 8.4 percentage points higher than that of the control group. Some of the analysis suggested that girls gained more from the intervention than did boys. Students from all types of schools, responded equivalently to the intervention. Health beliefs about barriers to preventive action were not influenced by the intervention.
  
  
  CONCLUSIONS
  This intervention increased students' knowledge about how to build healthy bones; however, the real challenge lies in building on that knowledge gain to influence behaviors. The modest gain in knowledge also suggests that educational interventions of this type should be tested with younger children, who might be more receptive.
