[Daily practice using guidelines for prevention and treatment of osteoporosis. Risk factors for fracture and guideline for prevention of fracture].

In 2006, a set of guidelines was released in Japan regarding the initiation of medical treatment to prevent fragility fracture with risk factors considered. In February this year, a WHO working group announced the development of the Fracture Risk Assessment Tool (FRAX), which estimates fracture risk based on age, sex, bone density at the femoral neck (body mass index if bone density is not available), previous fragility fracture in adulthood, parental fracture history at the femoral neck, current smoking, steroid use, secondary osteoporosis/rheumatoid arthritis, and alcohol consumption. And then, the NOF released guidelines incorporating FRAX in the US. WHO recommends that the threshold of medical treatment should be set based on each country's medical circumstances and healthcare economic situation.
