Percentage of Adults Aged 65 and Over With Osteoporosis or Low Bone Mass at the Femur Neck or Lumbar Spine: United States, 2005–2010Osteoporosis is an important risk factor for fragility fracture in older adults. According to the World Health Organization, osteoporosis is defined as a bone mineral density (BMD) value that is more than 2.5 standard deviation (SD) units below the mean BMD value for a young non-Hispanic white female reference group. Low bone mass, a milder reduction in BMD, is defined as a BMD value between 1.0 and 2.5 SD units below the mean value for a young non-Hispanic white female reference group. Recent estimates of the prevalence of osteoporosis and low bone mass at the femur neck or lumbar spine in U.S. adults focused on adults aged 50 and over. However, there is also interest in the prevalence of osteoporosis among adults aged 65 and over because most adults in this group are eligible for Medicare coverage.
