<b>Objectives:</b> This study was designed to assess the awareness of women of the risk factors and preventive measures of osteoporosis.<br /> <b>Methods:</b> This is a cross-sectional study that was conducted in Jordan. During the study period, a convenience sample of women were invited to participate via a survey link communicated through social media. Linear regression was used to screen independent variables affecting participants’ awareness of osteoporosis, its risk factors, and preventive measures.<br /> <b>Results:</b> 426 women agreed to participate in this study, with a median age of 38.5 years (IQR=16.0). Results showed that women have a median awareness score of 5.0 out of 9.0 (IQR=4.0) about osteoporosis risk factors, whereas women with higher educational levels (diploma or higher) and those with medical-related degrees have a higher awareness about osteoporosis risk factors compared to others (p≤0.05).<br /> Medical websites were the primary source used to obtain information about osteoporosis by the participating women (n=236, 55.4%). Also, results showed that more than 90% of the women believed that osteoporosis is a chronic silent disease that makes your bones less dense and more fragile (n=418, 98.1%), and that bone strength may increase by taking vitamin D and calcium (n=405, 95.0%).<br /> <b>Conclusion:</b> This study showed that women had an intermediate level of awareness of osteoporosis and prevention measures. The importance of medical websites and social media as sources of information was also demonstrated. More public targeted campaigns are needed to promote awareness of osteoporosis, its risk factors, prevention, and treatment.
