Crandall, MD, MS1; Joseph Larson, MS2; Nicole C. Wright, PhD3; et al OBJECTIVETo assess whether a second BMD measurement approximately 3 years after the initial assessment is associated with improved ability to estimate fracture risk beyond the baseline BMD measurement alone.In this prospective observational study 7419 women from The Women’s Health Initiative with a mean (SD) follow-up of 12.1 (3.4) years Incident major osteoporotic fracture (ie, hip, clinical spine, forearm, or shoulder fracture), hip fracture, baseline BMD, and absolute change in BMD were assesseda second bone mineral density (BMD) assessment approximately 3 years after the initial measurement was not associated with improved risk discrimination, beyond the initial BMD assessment, between women who did and did not experience hip fracture or major osteoporotic f
