According to the National Osteoporosis Foundation, risk factors for osteoporosis include:
- Female gender
- Age
- Family history of osteoporosis
- Caucasian or Asian descent
- Low body mass
- Slender body build
- Early estrogen deficiency
- Smoking
- Excessive use of alcohol
- Low-calcium diet
- Sedentary lifestyle
Postmenopausal women may also be vulnerable to vertebral fracture,1 which is the most common type of osteoporotic fracture.2
- Vertebral fractures lead to an increased risk for subsequent vertebral fractures3
- 20% of women will experience another fracture within the first year after an initial vertebral fracture4
Frequency of selected outcomes in women without previous vertebral fracture
Vertebral fracture is more common than other events in postmenopausal women with osteoporosis.

Data reflect event rates only. They are not a comparison of the severity of events.
Absence of first fracture reduces probability of subsequent fractures6,7
At T-score -3.0, absolute fracture risk was 24% in women with prevalent vertebral fracture(s) compared with 7% in women without prevalent fracture(s), for a threefold difference.†,8

†Data are from pooled placebo groups from the Fracture Prevention Trial and Multiple Outcomes of Raloxifene Evaluation (MORE) trial.
