Results: The mean scores of knowledge and health belief were $12.7{pm}3.81$ and $90.9{pm}12.66$, respectively. There was a statistically significant correlation between osteoporosis knowledge and health belief (p<.001). Also, a statistically significant correlation was found between health belief and health behavior (p<.001). According to the regression model, knowledge, perceived benefit, perceived barrier, family history of osteoporosis, and health interest explained 6.7% of total variance in health behavior.
