The Womens Health Initiative Hip Fracture Risk Calculator, available online, can help women over 50 gauge their bone health.
The calculator was created from data gathered from 162,000 women who took part in the Womens Health Initiative (WHI), the largest-ever study of womens health done in the US.
This perhaps could even be called an improvement on bone scan. For while scans can detect low bone density and osteoporosis, which puts a person at risk for fracture, most hip fractures occur in women who dont have osteoporosis, reports The New York Times.
In predicting the risk of bone fracture, the calculator takes into account factors like whether the womans parents suffered from a hip fracture at an early age, whether a woman has fractured a bone before the age of 54, if she is a smoker and whether she takes corticosteroids.
Lead author Dr. John Robbins, a professor at the University of California, Davis, School of Medicine, says that many women at risk, including African-American women or those who are overweight or have normal bone density, often arent screened for bone health because doctors assume they arent at risk for a fracture.
Doctors have a hard time looking at multiple factors,' says Dr. Robbins. They have a mindset that its a disease of thin, Caucasian women, and thats not really true.'
The calculator predicts a womans five-year risk of hip fracture. But just because a woman appears to be at high risk doesnt mean she should take bone-building drugs, notes Dr. Robbins. Although bone-building drugs have been shown to improve bone density, theres no evidence that a woman with normal bone density, but still at high fracture risk, would benefit from using the drugs.
