Editor's Note: In this issue of the JBMR, we introduce a new feature called Viewpoints. The intent of Viewpoint articles is to provide rapid, critical commentaries, generally reflecting differing perspectives, on pressing topics arising in the bone field that the editors believe deserve immediate discussion and dissemination. Viewpoints will be concise, focused opinions of new original studies or other issues that are deemed to have immediate impact on understanding bone and mineral biology or clinical practice. The inaugural Viewpoint articles, which appear in this issue, address the recent controversy surrounding the proposed frequency for performing bone mineral density in older postmenopausal women. Bone mineral density (BMD) testing by dual‐energy X‐ray absorptiometry (DXA) is the international standard for the clinical assessment of skeletal health. DXA is used to diagnose osteoporosis, to assess fracture risk, and to monitor changes in BMD over time. These clinical applications are supported by the following:
