25-Hydroxyl Vitamin D Levels and the Risk of Mortality in the General Population (2008)

Conclusion: This study followed and the tested the vitamin D levels of 13,331 adults for a period of 6-12 years. In a controlled analysis, those in the lowest vitamin D level quartile were found to have a 26% increased rate of all-cause mortality compared to those in the highest vitamin D level quartile. In the unadjusted analysis, the mortality risk was 78% higher.


Low Serum Concentrations of 25-Hydroxyvitamin D in Older Persons and the Risk of Nursing Home Admission (2006)

Conclusion: A 6-year study of 1,260 independent elderly people in Amsterdam found that those with lower vitamin D levels were more likely to end up in nursing homes.


Vitamin D Deficiency Is Associated With Low Mood and Worse Cognitive Performance in Older Adults (2006)

Conclusion: 40 elderly people with alzheimer’s disease and 40 non-demented elderly people who were participating in studies at the Alzheimer’s Disease Research Center were evaluated. Their vitamin D levels, physical performance, and cognitive/mental health were measured with a variety of mental health tests. The vitamin D results were not good. The average level of the entire group was only 18.5 ng/ml and 58% had “abnormally low” vitamin D levels. Those who were vitamin D-deficient were found to have a higher prevalence of mood disorders and scored worse on the Short Blessed Test (SBT) and the Clinical Dementia Rating test (CRD).


Serum Vitamin D and Falls in Older Women in Residential Care in Australia (2003)

Conclusion: This study of 1,619 elderly women living in nursing home facilities found that 22% of them women receiving low-level care had a severe vitamin D deficiency of <10 ng/ml and a shocking 45% of the women in high-level care were deficient below 10 ng/ml. The study also found that with each doubling of vitamin D levels, the risk of falling among the women dropped by 20%.


Relation Between Vitamin D, Physical Performance, and Disability in Elderly Persons (2002)

Conclusion: 269 elderly people living in retirement homes were evaluated for their vitamin D levels their physical performance in isometric strength tests and a 6-minute walking test. The rate of vitamin D-deficiency was significantly higher in the women than in the men and vitamin D status was significantly correlated with physical performance in the female subjects. Among the women, those with the lower vitamin D levels demonstrated lower arm and leg muscle strength and reported more disability than those with higher vitamin D levels. The study also found that vitamin D levels were significantly lower in the winter for everyone.
