Osteoporosis, or porous bone, is a disease characterized by low bone mass and structural deterioration of bone tissue, leading to bone fragility and an increased susceptibility to fractures, especially of the hip, spine, and wrist, although any bone can be affected.
Osteoporosis is a major public health threat for an estimated 44 million Americans, or 55 percent of the people 50 years of age or older. In the U.S. today, 10 million individuals are estimated to already have the disease and almost 34 million more are estimated to have low bone mass, placing them at increased risk for osteoporosis.
- Of the 10 million Americans estimated to have osteoporosis, eight million are women and 2 million are men.
- One in two women and one in four men over age 50 will have an osteoporosis-related fracture in her/his remaining lifetime.
- Significant risk has been reported in people of all ethnic backgrounds.
- While osteoporosis is often thought of as an older person's disease, it can strike at any age.
Women
- Eighty percent of those affected by osteoporosis are women.
- Five percent of non-Hispanic black women over age 50 are estimated to have osteoporosis; an estimated additional 35 percent have low bone mass that puts them at risk of developing osteoporosis.
- Ten percent of Hispanic women aged 50 and older are estimated to have osteoporosis, and 49 percent are estimated to have low bone mass.
- Twenty percent of non-Hispanic white and Asian women aged 50 and older are estimated to have osteoporosis, and 52 percent are estimated to have low bone mass.
Men
- Twenty percent of those affected by osteoporosis are men.
- Seven percent of non-Hispanic white and Asian men aged 50 and older are estimated to have osteoporosis, and 35 percent are estimated to have low bone mass.
- Four percent of non-Hispanic black men aged 50 and older are estimated to have osteoporosis, and 19 percent are estimated to have low bone mass.
- Three percent of Hispanic men aged 50 and older are estimated to have osteoporosis, and 23 percent are estimated to have low bone mass.
