Women Can Help Develop Better Treatments for Osteoporosis

CINCINNATI—Women between the ages of 18 and 35 can help researchers understand the effects of some medications for postmenopausal osteoporosis and hasten development of more effective treatments for the condition.


Researchers at the University of Cincinnati (UC) and six other sites across the country are studying how bone markers change during a normal menstrual cycle in premenopausal women.


“Bone markers are molecules that can be measured in the blood. These molecules tell us how much change is happening in the bone,” says Margery Gass, MD, professor of obstetrics and gynecology at UC and the national principal investigator for the study.


Bone is a complex living tissue that constantly renews itself. The body builds and stores bone tissue efficiently until age 30–35. With aging, bones begin to break down faster than new bone is formed. This breakdown of bone, osteoporosis, is more prevalent in women than men. Women have smaller bones to start with, and the loss of estrogen during menopause causes them to lose bone more rapidly for a short period of time.


“Most people don’t realize that bone is a dynamic organ that builds and dissolves in response to the stresses placed on it,” says Dr. Gass. “Bone metabolism is also affected by hormones, which fluctuate during a woman’s menstrual cycle.


“Synthetic hormones, such as those in birth control pills, also affect bones—in general, they help protect the bone and increase bone density. That’s why we want to study the bone markers of women who are not taking oral contraceptives,” Dr. Gass says.


According to Dr. Gass, bones have many markers, and researchers are unsure which are the best to measure.


“This study is important, because if we can isolate which bone markers best reflect the quality of bone in premenopausal women, we can develop better therapies to treat postmenopausal women who lose more bone than they build.


“Study participants could be helping us develop better treatments that may help the women they love—mothers, grandmothers, even themselves as they get older,” says Dr. Gass.


Researchers in this study are evaluating bone markers of both white and black women, but more black volunteers are needed.

May is National Osteoporosis Awareness Month.


According to the National Osteoporosis Foundation, osteoporosis is a major public-health threat for an estimated 44 million Americans, or 55 percent of people 50 years of age and older. In the United States, 10 million people are estimated to already have the disease.
