Osteoporosis - A Short Summary

Risk factors for Osteoporotic Fracture

(The four items in boldface type are key factors in determining risk of hip fracture independent of BMD)

Nonmodifiable

  • Personal history of fracture as an adult
  • History of fracture in first-degree relative
  • Caucasian/Asian race
  • Advanced age
  • Female sex
  • Dementia
  • Poor health/frailty

Potentially modifiable

  • Current cigarette smoking
  • Low body weight (<127 lbs)
  • Estrogen deficiency: early menopause (before age 45) or bilateral ovariectomy or prolonged premenopausal amenorrhea (>1 year)
  • Low calcium intake (lifelong)
  • Alcoholism
  • Impaired eyesight despite adequate correction
  • Recurrent falls
  • Inadequate physical activity
  • Poor health/frailty

Who Should Be Tested?

  • All women age 65 and over
  • All postmenopausal women under age 65 with risk factors (besides menopause)
  • Postmenopausal women with fractures
  • Women who are considering therapy for osteoporosis, if BMD testing would facilitate the decision
  • Women who have been on HRT for prolonged periods

Who Should Be Treated?

BMD T-ScoreACTION
Below -2.0 in absence of risk factorsInitiate therapy
Below -1.5 if other risk factors are presentInitiate therapy
Women over age 70 with multiple risk factors
(especially those with previous nonhip, nonspine fractures)
Initiate therapy

As part of any pharmacologic treatment program for osteoporosis, patients should be specifically counseled on the importance of calcium, vitamin D, and exercise.
