Women’s Health Initiative (WHI)
Hip Fracture Risk Calculator:
This calculator gives an approximate prediction of the risk of hip fracture over the next 5 years for postmenopausal women between the ages of 50 and 79. This is not a substitute for advice from a medical professional. Only your doctor can tell you what treatments may be suitable to reduce your risk of fracture. Use at your own risk. disclaimer

This calculator has been developed and tested on participants from the Women’s Health Initiative (http://www.nhlbi.nih.gov/whi/). The calculator has not been tested on an unhealthy population of postmenopausal women and may become unreliable. The construction of the model is described in the manuscript “Factors Associated With 5-Year Risk of Hip Fracture in Postmenopausal Women (John Robbins; Aaron K. Aragaki; Charles Kooperberg; Nelson Watts; Jean Wactawski-Wende; Rebecca D. Jackson; Meryl S. LeBoff; Cora E. Lewis; Zhao Chen; Marcia L. Stefanick; Jane Cauley JAMA. 2007;298(20):2389-2398.).

* Expenditure of physical activity (includes walking, mild, moderate and strenuous activity) in METs per week.
Examples of MET expenditure by physical activity are given below.

Activity MET hours
1 hour of walking (about 2.5 miles) 3.0
30 min. of aerobics/aerobic dance 3.0
30 min. of jogging (2.5 to 3 miles) 4.25
1 hour of tennis 7.0
30 min. of stationary bicycle 2.75
1 hour of dancing 4.5
1 hour of bowling 3.0
A woman walks for 30 minutes on Monday and Wednesday, jogs for 30 minutes on Tuesday and Thursday and
bowls for an hour on Saturday will expend 14.5 MET hours for that week (1/2*3.0 + 1/2*3.0 + 4.25 + 4.25 + 3.0 = 14.5)
