title: Osteoporosis diagnosis and screening.
abstract: Osteoporosis and osteoporotic fracture are major causes of morbidity and mortality in the United States and worldwide. Nearly half of all women and one quarter of men >50 years of age will experience an osteoporosis-related fracture during their lifetime. The diagnosis of osteoporosis in postmenopausal women and older men can be made definitively by comparing bone mineral density (BMD) measurements from dual-energy x-ray absorptiometry (DXA) to mean peak bone mass in young adults. Efforts to increase access to DXA and improve the sensitivity and specificity of osteoporosis risk assessment instruments may help ensure that individuals with osteoporosis are diagnosed early. The early identification of individuals with low BMD and/or clinical risk factors, accurate diagnosis of osteoporosis and osteopenia, and initiation of appropriate treatment are crucial to reducing the incidence of vertebral and nonvertebral fractures. The World Health Organization is moving toward absolute risk assessment and this may help to better identify patients for screening and treatment in the future.
