Vitamin D and Fall Risk in Seniors
Vitamin D and Fall Risk
Along
with the majority of people in the north during the winter months, many seniors
in retirement centers are also vitamin D deficient. Many older individuals
experience a loss of muscle mass and muscle strength that is directly related
to loss of bone. Elderly with low intake of vitamin D may have decreased renal
production of calcitrol and may be more at risk for falls due to resulting
proximal myopathy.
Some
studies have suggested that supplemental vitamin D may decrease seniors’ fall
risk. This may be due to the decreased psychomotor functioning and increased
sway that occurs with vitamin D deficiency that increases fall risk.
Such studies that have proven that vitamin D supplements
are beneficial for improving fall risk include meta-analysis was conducted by
Bischoff-Ferrari, Dawson-Hughes, and Staehelin et al. This study reviewed eight
randomized control trials of supplemental vitamin D. This review found that
vitamin D in a dose of 700-1000 IU per day reduced the risk of falls in older
individuals by 19%. Doses less than 700 IU did not reduce the risk of falls.
However,
a recent meta-analysis has suggested the opposite. This study was a meta-analysis of 20 studies
that looked at the connection between supplemental vitamin D and fall risk.
This review showed that supplemental vitamin D did not improve seniors’ fall
risk more than 15 percent so the effect of vitamin D supplementation was not
seen as significant.
Even
though the effects of vitamin D supplementation on fall risk in the elderly is
still unclear, it is important to look at the importance of vitamin D in the
diet. Supplementation has been shown to improve muscle function, walking
distance, and functional ability. Whether or not these effects directly relate
to improving fall risk may still be debatable, but it is clear that seniors need to
avoid Vitamin D deficiency through diet and supplementation for optimal health.
