Description:Data from the National Health and Nutrition Examination Survey, 2017-2018
• In 2017-2018, the age-adjusted prevalence of osteoporosis at either the femur neck or lumbar spine or both among adults aged 50 and over was 12.6% and was higher among women (19.6%) compared with men (4.4%).
• The prevalence of low bone mass, a precursor of osteoporosis, at either the femur neck or lumbar spine or both among adults aged 50 and over was 43.1% and was higher among women (51.5%) compared with men (33.5%).
• Osteoporosis prevalence increased from 2007-2008 through 2017-2018 among women but not men.
• Low bone mass prevalence did not change between 2007-2008 and 2017-2018 for either men or women.
Osteoporosis is the most common bone disease and is characterized by weakening of bone tissue, bone structure, and strength, and may lead to increased risk of fractures (1). Low bone mass increases the risk of developing osteoporosis (2).
In the United States in 2010, an estimated 10.2 million people aged 50 and over had osteoporosis and about 43.3 million more people had low bone mass (3). This report provides prevalence estimates of osteoporosis and low bone mass among adults aged 50 and over in the United States in 2017-2018.
