Wanted: Older Women to Bulk Up a Little
UConn Health Center Needs Volunteers for Bone Health and Balance
Study
FARMINGTON, CONN. – Women over the age of 65 are needed for a study
to evaluate the effect of exercise and the supplement DHEA (dehydroepiandrosterone)
on their bone health, strength and balance.
The women will be given DHEA, a natural hormone produced by the body,
and twice weekly exercise sessions of yoga or gentle aerobics for a
six-month period to see if the combination improves their bone strength
and balance.
“Frailty in older women is involved in about 90 percent of hip
fractures, which can sharply curtail activities and even independent
living,” according to Anne Kenny, M.D., UConn Center on Aging, who is
the principal investigator for the study, funded by the National Space
Aeronautical Administration (NASA) which is interested in strength and
bone health for astronauts. “Our goal is to see whether DHEA, a
naturally occurring hormone, and exercise can increase older women’s
strength and balance and help them prevent falls and fractures,” says
Kenny. “We want to see if it will help them bulk up a little. We know
that astronauts lose bone and muscle while they are in space and their
DHEA levels decline. If we can find an association between DHEA and
strength in frail adults, it might be helpful for astronauts as well.”
DHEA is a hormone normally produced by the adrenal gland in humans.
“DHEA may have a slightly unsavory reputation because it was abused by
professional athletes searching for peak performance,” says Kenny. “In
fact, it’s a naturally occurring hormone produced by the adrenal glands
that peaks in humans in the mid-20s and then declines, as much as 80
percent by age 70. Low levels of DHEA have been associated with higher
death rates and higher fracture rates. We want to see if DHEA
supplements in small amounts are beneficial to bone, muscle and balance
in older adults,” says Kenny. “We all lose muscle as we age, whether we
want to or not,” says Kenny. “Perhaps hormones like DHEA are part of the
reason why it’s a little bit easier to stay fit when we’re younger.”
Women who volunteer for the study will participate in a brief
questionnaire and have their DHEA levels tested by a simple blood test.
“While DHEA levels go down generally as we age, the decline can vary
significantly among individuals. We are looking for volunteers with low
levels of the hormone because we will be giving DHEA supplements and we
don’t want their levels to get too high,” says Kenny.
