July 17, 2013. The results of a study published on July 17, 2013 in the Journal of Clinical Endocrinology & Metabolism reveal a greater risk of difficulty with performing everyday tasks among older men and women who are deficient in vitamin D.
The study included 597 men and women aged 55 to 65 and 762 subjects aged 65 to 88 enrolled in The Longitudinal Aging Study Amsterdam. Questionnaires administered upon enrollment and at three and six years of follow-up provided information on the participants’ ability to perform such activities as climbing or descending stairs, dressing and undressing, sitting down and standing up from a chair, and other tasks.
Among the older group, a serum 25-hydroxyvitamin D level of less than 20 nanograms per milliliter (ng/mL) was associated with a 70% greater risk of having one or more functional limitations in comparison with a level of 30 ng/mL or higher, and for those in the younger group, the risk associated with low vitamin D was twice as high. Older subjects who had the lowest vitamin D levels had double the risk of developing additional limitations at three years of follow-up compared to those in the highest group, and for the younger group, the risk tripled after six years.
"Seniors who have low levels of vitamin D are more likely to have mobility limitations and to see their physical functioning decline over time," commented lead author Evelien Sohl, MSc, of VU University Medical Center. "Older individuals with these limitations are more likely to be admitted to nursing homes and face a higher risk of mortality."
"The findings indicate low vitamin D levels in older individuals may contribute to the declining ability to perform daily activities and live independently," Sohl added. "Vitamin D supplementation could provide a way to prevent physical decline, but the idea needs to be explored further with additional studies."
