Discussion
This study showed that a key prevention method for osteoporosis is that of community-based intervention strategies using behavior change models such as the health belief model. There were significant differences between mean scores of knowledge before, immediately after and six months later the intervention in the case group. The knowledge scores in this group increased significantly after the intervention. This is consistent with results of Ghaffari et al.13, Winzenberg et al.14 and Wafaa Hassan et al.15. Although the mean score of knowledge significantly increased in the control group as well, there is a significant difference between the mean scores of knowledge of the two groups. The increase in knowledge and other constructs can be the participants' access to information as well as their participation in the training course held by the Fasa health center about diseases and health issues for women and health volunteers. The increase in knowledge score in the intervention group is significant and deserves consideration.
