Disease may threaten young women.(osteoporosis)
2002 SEP 12 - (NewsRx.com & NewsRx.net) -- A University of Arkansas study shows that 2% of college-age women already have osteoporosis. A further 15% have sustained significant losses in bone density, and may be well on their way to developing the disease.
The study also reveals some surprising risk factors, which may help explain why so many young women have dangerously low bone density - and provide them with the information they need to avoid problems in the future.
"I want women not just to live longer, but to live better," said dietician and health sciences professor Lori Turner. Turner thinks that millions of young women may be putting themselves at risk for developing osteoporosis up to 50 years before symptoms appear. Analyzing the diet and exercise habits of 164 college-age women, she came up with some surprising conclusions about the origins of this complex disease.
Turner collected bone density readings from the hips and spines of women between the ages of 18 and 30, using DEXA (dual energy x-ray absorptiometry) scans to generate complete pictures of her subjects' skeletons. A computer then analyzed these images, measuring the bone densities of the young women and comparing them to a database collected by the National Center for Health Statistics. Turner then correlated her subjects' bone densities with a barrage of possible risk factors: exercise, diet, and other lifestyle habits.
After putting her data through statistical analysis, Turner discovered something shocking: 2% of her young subjects already had bone densities low enough to cause osteoporosis of the spine. A further 15% had osteopenia - their low bone densities put them at increased risk for developing osteoporosis.
Turner found that Depo-Provera, a common method of birth control that consists of hormone injections every 3 months, was associated with significant bone loss, especially with long-term use. Depo-Provera is far more convenient than the Pill and just as effective, but many young women aren't aware of its potential risks. Turner thinks that women who stick with Depo-Provera should be aware of this possible side effect and consider having their bone density levels checked.
Some of Turner's subjects had extremely low body weights, which they maintained almost exclusively through dieting. Wanting to ...
