Rescreening Intervals for Osteopenia
Technical Considerations for Timing
- A minimum 2-year interval is required between scans to reliably detect true bone density changes, according to guidelines from the American College of Physicians, as the precision limitation means that scanning more frequently than 2 years may lead to false conclusions about bone loss or gain 1
- The yield of repeated screening increases in older women, those with lower baseline BMD, and those with additional fracture risk factors, as stated by the American College of Physicians 1
Clinical Context That Modifies Intervals
- Shorten rescreening intervals in the presence of new glucocorticoid therapy or other medications causing bone loss, as recommended by the National Osteoporosis Foundation 2
- Shorten rescreening intervals in the presence of incident fragility fracture, as recommended by the National Osteoporosis Foundation 2
- Shorten rescreening intervals in the presence of development of conditions associated with secondary bone loss, such as hyperparathyroidism, hypogonadism, or chronic inflammatory diseases, as recommended by the National Osteoporosis Foundation 2
- Shorten rescreening intervals in the presence of significant weight loss, particularly if weight drops below 70 kg, as recommended by the National Osteoporosis Foundation 2
- Consider longer intervals for younger postmenopausal women (60-65 years) without additional risk factors, as suggested by the National Osteoporosis Foundation 2
