title: The relationship of alcohol use and physical activity from an ecologic perspective.
abstract: OBJECTIVE
  To determine the predictors of alcohol use (AU) and their relationship to physical activity (PA) among adolescents and to examine differences among groups using an ecologic model.
  
  
  METHODS
  Cross sectional secondary analysis of 11,432 adolescents (51% 8th and 49% 10th graders).
  
  
  RESULTS
  Attitude, perception of risk, and academic performance were the strongest predictors of AU. PA did not moderate, but it had a positive influence on AU in 10th graders. Differences were observed among groups.
  
  
  CONCLUSIONS
  Nurses can address individual and school factors in an effort to decrease AU and guide nurses in creating an individualized plan.
