title: A cluster analytic study of osteoprotective behavior in undergraduates.
abstract: OBJECTIVE
  To derive an empirical taxonomy of osteoprotective stages using the Precaution Adoption Process Model (PAPM) and to identify the predisposing factors associated with each stage.
  
  
  METHODS
  An anonymous survey was completed by 504 undergraduates at a Midwestern public university.
  
  
  RESULTS
  Cluster analytic findings indicate that only 2 osteoprotective stages exist in young adults: less engaged and engaged. These two groups were best distinguished by health motivation, sex, a perceived barrier to exercise, and exercise self-efficacy.
  
  
  CONCLUSIONS
  Fine-grained stages of osteoprotective behavior are not apparent in young adults, suggesting that the PAPM may not be useful for explaining the adoption of osteoporosis precautions.
