Preventing Osteoporosis
by: Vikki Franklin

Sticks and stones may break your bones, as the old saying goes, but a far more likely culprit is osteoporosis.
Osteoporosis-or porous bone-is a disease in which bones become fragile and more likely to break, which puts its victims at an increased risk for fractures of the hip, spine, and wrist.

  Current figures show osteoporosis is a threat to 28 million Americans, 80 percent of whom are women. In the United States, 10 million people already have the disease, and 18 million more have low bone mass, placing them at increased risk for osteoporosis.

  "Osteoporosis often is called the 'silent disease' because symptoms might not appear until your bones become so brittle that you suffer a broken bone after a fall or even a bump," says Hartmut Malluche, M.D., chief of nephrology, bone, and mineral metabolism at the University of Kentucky Chandler Medical Center. The disease is responsible for about 1.5 million fractures annually in the United States.

  In Kentucky, the rate of osteoporosis is slightly higher than the national average, probably because of the high smoking rate in the state, Malluche says. It's estimated that by 75 years of age, 90 percent of women in Kentucky have osteoporosis.

  No definitive cure has been found for advanced osteoporosis, and prevention should begin early. "It's important to build up the peak bone mass at the time of the completion of growth," Malluche says. That means prevention begins in the adolescent years when bone is forming, making teen smoking even more harmful.

  Getting enough calcium and vitamin D in your diet, particularly as a child and adolescent, can build strong bone, helping stave off the disease. "The average American diet is relatively low in calcium. It's important to get between 1,000 and 1,500 milligrams of elemental calcium per day, including dietary intake," Malluche explains.

  Weight-bearing exercise such as walking also has been shown to help prevent bone loss.

  The disease is detected through bone density tests, which painlessly measure bone density in various parts of the body. If a problem is found, several new medications are available to prevent and/or treat the disease, although nothing completely restores bone loss.

  "As baby boomers get older, osteoporosis is going to become more common, so we're just beginning to see the tip of the iceberg," Malluche says. "Especially for women, it's important to talk with your doctor about preventing osteoporosis-and to do it early."
