Purpose: Osteoporotic fractures are a significant growing problem of public health, so the use of tools that allow a proper risk assessment and establishing preventive policies should be a priority. This paper assesses the risk of different types of fractures as much in men as in menopausal and non menopausal women. Patients and methods: A descriptive crosssectional study in working population from the Spanish health system aged between 40 and 65. The risk of increased osteoporotic hip fracture is calculated using the FRAX tool for the Spanish population. 749 randomly selected workers were included in the study, 251 men, 251 non menopausal women and 247 post-menopausal women. Results: Mean ages were 46.8 years in men, 43.9 years in non-menopausal women and 52.3 years in the menopausal. The average risk of hip fracture and major osteoporotic was 2.1 ± 1.33 and 0.22 ± 0.36 in males, 2.65 ± 2.16 and 0.27 ± 0.94 in non-menopausal women 3.1 ± 2.93 and 0.44 ± 0.88 in menopausal women. No men, 0.8 % of menopausal women and 2 % of menopausal treatment had positive criteria for treatment according to the National Osteoporosis Foundation. Conclusion: The risk of osteoporotic fractures in this group is very low, however the use of the FRAX tool can be very useful to detect the risk in its early stages and establishing prevention policies that allow cost savings and improve the health of our workforce.
