  Osteoporosis is a systemic skeletal disorder characterized by reduction of one mass, deterioration of bone structure, increasing bone fragility, and increasing fracture risk. Prevention of osteoporosis during childhood and adolescence is one of the most important issues in World Health Organization.

The standard questionnaire was completed three times (before, immediately, and 2 months after education) and FFQ questionnaire was completed two times (before and 2 months after education) by the students. After pre-test, four educational session classes in the experimental group were performed. Finally, data collected were analyzed by SPSS 18 computer software.
  
  
  RESULTS
  The result of this study showed a significant increase in the mean score of knowledge, perceived susceptibility, seriousness, benefits, barriers, as well as taking health action among girl students in the experimental group.
