In addition to femoral neck (hip) BMD, age, gender, fracture history and steroid use, FRAX also takes into account other clinical risk factors to calculate the absolute 10-year risk of a hip fracture or other major osteoporotic fracture (spine, forearm, upper arm). These factors include:

  • BMI (weight to height ratio calculation)
  • Parental hip fracture
  • Rheumatoid arthritis
  • Other secondary conditions that contribute to bone loss
  • Current smoking
  • Alcohol intake (three or more drinks per day)
