Does low vitamin D status contribute to "age-related" morbidity?

Abstract

It is increasingly appreciated that vitamin D plays important physiological roles beyond the musculoskeletal system. As such, it is plausible that endemic vitamin D deficiency contributes to much nonskeletal morbidity that adversely affects quality of life with advancing age among older adults. This overview will explore the evidence for, and potential involvement of, vitamin D deficiency in nonbone conditions that are currently accepted as "age-related" morbidity among older adults.
