SEATTLE, Oct 04, 2004 (United Press International via COMTEX) -- New York researchers say more than half of women currently treated for osteoporosis don't have enough vitamin D in their bodies.

The researchers, in a study discussed at meeting Monday of the American Society for Bone and Mineral Research in Seattle, said vitamin D inadequacy is still highly prevalent in this population.

"While women may know that calcium is an important part of bone health, this research shows that some women on treatment for osteoporosis are unaware of the important role vitamin D plays or are simply not getting adequate amounts as part of their treatment regimen," said Ethel Siris of the Columbia University College of Physicians and Surgeons.

More than 10 million people in the United States are estimated to have osteoporosis and 80 percent are women. Vitamin D, an essential component of osteoporosis therapy, helps to ensure the body absorbs and retains calcium and phosphorus, both critical for building bone.

The National Osteoporosis Foundation advises getting recommended daily amounts of vitamin D and calcium as one of the five steps involved in bone health and osteoporosis prevention.
