CDC: One in Four Older Women Has Osteoporosis
(HealthDay News) — The prevalence of osteoporosis and low bone density has been examined among adults aged ≥65 years. The findings were published online Aug. 13 by the U.S. Centers for Disease Control and Prevention's National Center for Health Statistics (NCHS).
Anne C. Looker, PhD, and Steven M. Frenk, PhD, from the NCHS, used data from the 2005–2010 National Health and Nutrition Examination Surveys to examine the prevalence of osteoporosis and low bone mass at the femur neck or lumbar spine among U.S. adults aged ≥65 years.
The researchers found that 16.2% of adults had osteoporosis, with age-adjusted prevalence being 24.8 and 5.6% among women and men, respectively. The unadjusted prevalence was 25.7 and 12.8% among those aged ≥80 years and those aged 65–79 years, respectively. The unadjusted prevalence of osteoporosis was 24.9, 15.7, and 10.3% among Mexican-Americans, non-Hispanic whites, and non-Hispanic blacks, respectively. Low bone mass was seen in 48.3% of adults aged ≥65 years, with higher prevalence seen among women vs. men (52.3 vs. 44.0%). Prevalence was higher in adults aged≥ 80 years vs. those aged 65–79 years (52.7 vs. 46.7%).
"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," the authors write. "There is also interest in the prevalence of osteoporosis among adults aged ≥65 because most adults in this group are eligible for Medicare coverage."
