The author of the study points out that a fracture of the hip cased by osteoporosis should be preventible. Monitoring of changes in height by primary care physicians could indicate the need for bone density testing at a much earlier stage in the the bone loss progression.
The results of the study showed that height loss of between 2 inches and 3 inches increased more than fourfold the chances the women had osteoporosis of the hip (verified by bone density testing). Odds of osteoporosis in the hip were nearly 10 times greater in women with 3 or more inches of height loss compared to women with less than an inch of loss. The average age of the women in the study was 60. All were post-menopausal, when the lack of estrogen production can lead to dramatic bone loss.
Osteoporosis is often called a "silent disease" because most patients feel no symptoms and it is often not diagnosed until a fracture has occurred. An estimated 30 million American women either have or are at risk for osteoporosis, which is responsible for about 300,000 hip fractures annually. Men account for 25 percent of the hip fractures nationally.
Broken hips can be catastrophic for elderly patients nearly 50 percent of sufferers never return to normal function, 25 percent require nursing home care and 20 percent die of infection, blood clots or other complications within six months after the fractures, he said.
In the future, bone density screening may become as routine as mammogram for women who have reached menopause. Until that happens monitoring height should be a part of every checkup after the age of 50.
