Low Levels of Vitamin D Associated
With a 50% Increase in Mortality
BIRMINGHAM, ALABAMA– New research conducted at the Wake Forest School of Medicine and published in The Journal of Clinical Endocrinology and Metabolism has revealed that a vitamin D deficiency can dramatically increase the mortality rates of older adults.
The researchers explained that there have been numerous previous studies that suggested that Vitamin D may play a role in protecting against cardiovascular disease and cancer as well as being able to protect against the risk of bone fracture. But, this study has confirmed the actual risk to mortality in older adults.
In the study there were 2638 subjects between the ages of 70-79. They were given a blood test at the beginning of the study and then every six months after that. The researchers compared blood levels of vitamin D to the deaths of participants.
The researchers concluded that levels of vitamin D that were lower than 30 mg/nl were directly connected to a significant rate of mortality from any cause.
According to lead researcher Stephen B. Kritchevsky, PhD:
"We observed vitamin D insufficiency (defined as blood levels <20 ng/ml), in one third of our study participants. This was associated with nearly a 50 percent increase in the mortality rate in older adults. Our findings suggest that low levels of vitamin D may be a substantial public health concern for our nation's older adults."
The researchers note that the good news is that vitamin D levels are relatively easy to increase through modest sun exposure, diet and supplements.
Based on the incredibly higher rate of mortality for people with low blood levels of vitamin D you might want to make sure that you have adequate levels in your blood.
