Osteoporosis or Low Bone Mass at the Femur Neck or Lumbar Spine in Older Adults: United States, 20052008,April 2012. Key findings – Data from the National Health and Nutrition Examination Survey, 20052008
- “Nine percent of adults aged 50 years and over had osteoporosis, as defined by the World Health Organization, at either the femur neck or lumbar spine. About one-half had low bone mass at either site, while 48% had normal bone mass at both sites.
- Estimates of poor skeletal status at the femur neck or lumbar spine when considered alone were not the same as estimates based on the two skeletal sites together because some individuals had the condition at one site but not the other.
- The prevalence of osteoporosis or low bone mass at either the femur neck or lumbar spine differed by age, sex, and race and ethnicity. The prevalence was higher in women and increased with age. Differences between racial and ethnic groups varied by sex and skeletal status category.”
