Is BMD testing appropriate for all menopausal women?
The United States Preventive Services Task Force has provided an evidence-based guideline indicating that bone mineral density (BMD) testing is appropriate for all women aged 65 or older. This does not preclude BMD testing in younger postmenopausal women but places the onus on the treating physician to justify the procedure to the patient and often the patient's insurance carrier. There are very few circumstances in which BMD testing is appropriate for healthy premenopausal women, but BMD testing in younger postmenopausal women is often appropriate: when there is a family history of osteoporosis with fracture, a personal history of fracture as an adult, and a medical, surgical or therapeutic history that might be associated with accelerated bone loss or increased risk of fracture. Medical conditions include intestinal diseases associated with malabsorption, such as non-tropical sprue, or primary hyperparathyroidism. Women who have neurologic conditions that increase the risk of falling should also be tested. There are data to suggest that patients with hemoglobinopathy are at increased risk for osteoporosis. Surgical conditions include the increasingly performed surgery for obesity and other surgery resulting in bowel resection (e.g., for inflammatory bowel disease). The major medication-related concern is corticosteroid therapy, but chronic or over-treatment with thyroxine, and chronic heparin therapy, should also be considered risk factors for osteoporosis. When performing a BMD test for the first time, it is essential to remember that 50% of women at menopause will have a negative T-score, but this does not imply that the patient has indeed lost any bone from her peak bone mass.
