- NEW YORK (Reuters
Health) -- The findings from a new study suggest that older persons may
cut their risk of falls by more than 20 percent by taking vitamin D supplements.
Further studies, however, are needed to determine what type of vitamin
D works best and at what dose, and to clarify the benefits in men.
-
- Although a few studies have shown a reduced risk of falls
with vitamin D use, many others have failed to show a benefit. To better
understand whether vitamin D protects against falls, Dr. Heike A. Bischoff-Ferrari,
from Harvard Medical School in Boston, and colleagues analyzed data from
ten previous studies that looked at the association in elderly populations.
-
- Five of the studies were included in the main analysis,
while the remaining five were used to verify the results, according to
the report published in the Journal of the American Medical Association.
-
- In the main analysis, vitamin D users were 22 percent
less likely to experience a fall than patients who received inactive "placebo"
pills or calcium. The authors estimate that 15 subjects would need to receive
daily vitamin D supplements in order to prevent one person from falling.
-
- In the second analysis, the risk reduction seen with
vitamin D use fell to 13 percent, but was still statistically significant,
the investigators note. Moreover, the protective effects were not dependent
on calcium use, duration of therapy, vitamin D type or gender.
-
- Due to limited numbers of subjects, the protective effect
observed for vitamin D use in men was not statistically significant, the
authors point out.
-
- "The role of calcium and the optimal amount necessary
in combination with vitamin D could not be clearly determined," the
researchers note.
