Osteoporosis in Men
Osteoporosis is not just a significant health problem for women. It is
also prevalent in aging men, yet the disease often goes undiagnosed or
untreated until a bone fracture occurs, according to a paper published
in the June 2006 issue of the Journal of the American Academy of
Orthopaedic Surgeons. These fractures, which are treated primarily by
orthopaedic surgeons, can play an important role in identifying men with
osteoporosis so the disease also can be treated.
It is estimated that more than two million men in the United States have osteoporosis. According to the paper, which is an extensive review of the current literature on this disease, 30 percent of hip fractures occur in men, and those men have twice the mortality rate of women during the initial hospitalization and first post-fracture year. One third of men who suffer a hip fracture lose independence and must move into a nursing facility or a relative's home. With 77 million baby boomers aging, the prevention, diagnosis and treatment of men with osteoporosis is crucial to preventing these fragility fractures.
"Osteoporosis is not only a women's disease--men also lose bone density as they age," said author Vonda J. Wright, MD, assistant professor in the Department of Orthopaedic Surgery at the University of Pittsburgh, and a Sports Medicine and Shoulder Fellow at the Hospital for Special Surgery in New York. "But because many of us physicians don't realize how common osteoporosis can be in men, we don't always look for it when a male patient has suffered a fracture. The fracture gets treated but the underlying disease does not, so the patient continues to be at risk."
Osteoporosis is often considered a woman's disease because it is linked to a loss of estrogen that occurs during aging. Because women have higher levels of estrogen, most of the research on osteoporosis has been focused on them. However, men also undergo a loss of estrogen and other hormones that affect bone density, albeit more gradually than women.
More than ten million people currently have osteoporosis; another 34 million have low bone mass and therefore are at risk of developing the disease. More than 2 million Americans sustain a fracture related to osteoporosis each year.
Bone is a living tissue composed mainly of calcium and protein which provide strength. Bone is constantly reforming (remodeling) as calcium is added to your bones and absorbed by your body.
Osteoporosis or "porous bone" develops when bone calcium is no longer replaced as quickly as it is removed, making the bone brittle. Half of all women over 50 will sustain an osteoporosis-related fracture sometime in their life. Men account for 20 percent of those affected by osteoporosis.
Factors that contribute to osteoporosis are:
- Aging
- Lack of weightbearing exercise
- Excessive thyroid or cortisone hormone
- Heredity, Caucasians and Asians are at greatest risk
- Smoking and excessive alcohol intake
- Reduced levels of estrogen after menopause
- Low calcium dietary intake, reduced calcium absorption and inadequate Vitamin D levels, which affect skeletal health.
